> take precedence over the requirements contained in this paragraph.

c\. Submittals. ‑ The delivery orders which require submittals shall
specify the material to be submitted. All of the material specified will
be considered a complete set; and where the material required is
specified as separate or distinguishable parts, a complete set shall
include all parts. Only complete sets shall be submitted.

When a delivery order involves submittal of original (non‑copied)
material, all original material, or as much thereof as is necessary to
form a complete set, shall be included in just one complete set. This
\"originals\" set shall be sent to Contracting Officer.

> The Contractor shall submit complete sets of required submittal

Submittals requiring certification by a registered professional shall be
signed and sealed.

d\. Review of submittals furnished for approval. ‑ The time required for
review of each submittal or resubmittal furnished for a delivery order
will not begin until the Government receives complete sets of all the
submittal materials required for that particular delivery order. The
number of calendar days required for review of drawings or data
submitted or resubmitted for approval will include the date the drawings
or data are received by the Government, and will extend through the date
of return mailing to the Contractor.

> Except as otherwise provided in the delivery orders for specific
> submittals, the Government may require and use 14 calendar days for
> review of each submittal or resubmittal furnished by the Contractor
> for approval, and this review time will apply to each separate
> submittal or resubmittal whether the submittals are approved, not
> approved, or returned for revision.
>
> If the Government uses time in excess of the specified number of
> calendar days for review of any submittal or resubmittal, additional
> time, not to exceed the excess time, will be added to the time allowed
> the Contractor for completion of the work affected by such excess
> time, to the extent it is demonstrated that the excess time caused
> delay. If the Government\'s review of two or more separate submittals
> or resubmittals is late and results in concurrent days of excess time,
> such days will be counted only once in computing an extension of the
> completion date. Further, if the Contractor fails to make complete
> approval submittals in the sequence and within the time periods
> specified in this contract, and thus precludes the Government from
> approving or considering for approval such submittals within the
> specified calendar day period, then the Contractor shall not be
> entitled to an extension of time allowed for completion of the work.
>
> Adjustment for Government delay in approving requests for approval of
> shop drawings or other technical data shall be made only to the extent
> that (1) Government approval was required under this contract, and (2)
> the requests for approval were properly and timely submitted and
> approvable. Any such adjustment shall be subject to the terms of
> paragraphs (b) and (c) of the Suspension of Work clause of this
> contract; however, no such delay shall be deemed to be a \"suspension
> order\" as the term is used in that clause.
>
> Unless otherwise specified, one set of the submittals required for
> approval will be returned to the Contractor either approved, not
> approved, or conditionally approved, and will be marked to indicate
> changes, if required. Submittals that are not approved or that require
> changes or revisions shall be revised and resubmitted for approval and
> shall show changes and revisions with revision date. All requirements
> specified for the initial submittal shall apply to any resubmittals
> required. Unless otherwise specified, all submittals which are to be
> resubmitted shall be resubmitted by the Contractor within 14 calendar
> days after the Contractor has received the Government\'s comments.

e\. Addresses. ‑ The Contractor shall send the submittals to the
applicable addresses listed below.

> \(1\) Contracting Officer, Attn: ALB-540, Bureau of Reclamation,
> Albuquerque Area Office, 505 Marquette N.W. Suite 1313, Albuquerque,

a\. Work Schedule: The schedule shall be submitted at the
pre‑construction meeting. When requested, the Contractor shall submit an
updated schedule within 3 working days.

2.7.3 Installation.

> a\. General: For all fence types, follow manufacturer's instructions
> and industry standards for installation of fence materials and
> information provided in each delivery order.

For barbed wire fence:

> Steel \"T\" posts shall not be used for end-panel, corner-panel,
> gate-panel, or stress-panel posts. Steel "T" posts shall be driven.
> The preferred material for end-panel, corner panel, gate panel, or
> stress-panel posts and the horizontal braces will be treated wood. Set
> wood posts in dug or drilled holes unless written authorization is
> obtained for driving wood posts.
>
> Setting Posts: Dig holes for setting wood posts to the depth as
> indicated in the individual delivery orders. Set posts plumb and to
> the spacing, grades and depths as indicated in the individual delivery
> orders, unless staked otherwise. Space within 6 inches of that
> dimension indicated on the individual delivery orders. Holes shall
> provide adequate open space around the post so that backfill can be
> tamped the full depth around the post. Backfill gradually and
> uniformly with soil
>
> around each post; compact backfill firmly from the bottom of the hole
> to the ground surface. Steel pipe or angle iron posts shall be set in
> holes and grouted solidly in position with cement grout or mortar.
> Post grout shall be a rapid setting commercial product manufactured
> for anchoring posts.

b\. Driving Posts:

Wood Posts: Drive only when approved by the Contracting Officer to the

> depth indicated on the individual delivery orders. Wood posts to be
> driven shall be machine-pointed on the end driven into the ground.
> Posts shall be driven plumb. Posts that are split, bent, or broomed,
> will not be accepted.
>
> Steel Posts: Drive steel posts into the ground to the depth indicated
> on individual delivery orders or until the anchor plate is slightly
> below the ground surface. Posts shall be driven plumb. Posts that are
> split, twisted, bent, or have broomed
>
> tops will not be accepted. When rock formations prevent driving remove
> anchor plate and excavate or drill holes a minimum of 18 inches deep
> and slightly larger than the diameter of the post. Place posts in the
> holes and grout the post solidly in position with cement grout or
> mortar.

c\. Corner Post, Gate Post, Stress Panel and End Panel Assemblies:
Construct as indicated in individual delivery orders or as staked in the
field. Construct stress panels on crests of hills, and a maximum of 15
feet center-to-center for barbed wire sections. In addition, stress
panels are required at points between which wire is to be stretched.
Construct end panels at the end of fence runs unless shown otherwise on
the drawings.

d\. Wire: Stretch tightly and staple to wood posts or securely attach to
steel posts with standard wire clips. Wire is properly stretched when it
is springy to the touch. Avoid excessive tension in the wire. Drive
staples into wood until the staple comes in contact with the wire
against the post, but not so tight as to crimp the wire or prevent free
movement of the wire between the post and the staple. Do not drive
staples parallel to the grain of the wood. Terminate wire at each end
post, gate post, corner post, or stress panel by wrapping wire around
the post two times and tie off by wrapping the incoming wire a minimum
of four times.

e\. Gates: Shall be installed according to the individual delivery
orders, and as

recommended by the manufacturer when applicable.

f\. Brace Wire: Shall be twisted tight with a lever arm. Leave one end
of the lever arm long enough to fasten behind the horizontal brace to
prevent wire from unwinding.

g.  Spiking: For spikes larger than 40d, pre-drilled lead holes shall be
    used. The hole

> diameter shall be three-fourths the diameter of the spike and drilled
> to a depth no greater than two times the length of the spike.

h\. Units: Wire fence will be measured and paid for by the foot of each
type of fence as measured along the ground surface next to the completed
fence, including distance across gate openings, end, stress, corner
panels, drainage crossings, and cattle guards.

2.7.4 Measurement and Payment

Wire fence will be measured and paid for by each type of fence as
measured along the ground

surface next to the completed fence, including distance across gate
openings, end, stress, corner panels, drainage crossings, and cattle
guards. Gates will be paid for separately and do not

include adjacent end or corner panels. These are separate items.

> pockets, streaks, voids, laminations, or other imperfections.

b\. Compacting clayey and silty materials. ‑ Where compaction of earth
materials containing appreciable amounts of clay or silt is required,
the materials shall be deposited in horizontal layers. The thickness of
each horizontal layer after compaction shall be not more than 6 inches.
If the surface of any compacted layer of earth fill is too dry or smooth
to bond properly with the layer of material to be placed thereon, it
shall be moistened and/or scarified in an approved manner to provide a
satisfactory bonding surface before the next succeeding layer is placed.

> Prior to and during compaction operations, the materials shall have a
> moisture content of not greater than 2 percentage points wet, or not
> less than 2 percentage points dry of optimum moisture content, and the
> moisture content shall be uniform throughout each layer.
>
> Insofar as practicable, as determined by the Contracting Officer's
> Representative, moistening of the material shall be performed at the
> site of excavation; but, if necessary, such moistening shall be
> supplemented by sprinkling at the site of compaction. If the moisture
> content is less than optimum for compaction by more than 2 percentage
> points, or is greater than optimum for compaction by more than 2
> percentage points, the compaction operations shall not proceed, except
> with the specific approval of the Contracting Officer's
> Representative, until the material has been wetted or allowed to dry
> out, as may be required, to obtain a moisture content within the
> tolerances permitted above, and no adjustment in price will be made on
> account of any operations of the Contractor in wetting or drying the
> materials or on account of any delays occasioned thereby.
>
> When the material has been conditioned as herein before specified, it
> shall be compacted by rollers or by hand or power tampers. Where hand
> or power tampers are used to compact soils in confined areas such as
> under pipe, they shall be equipped with suitably shaped heads to
> obtain the required density.
>
> The dry density of the portion of the soil passing the 3/4 inch sieve
> in the compacted material shall not be less than 95 percent of the
> laboratory maximum dry density as determined in accordance with ASTM D
> 698-98 test method. The compaction tests will be made by the
> Government or its representative. The maximum dry density of the soil
> obtained by ASTM D 698-98 is called the laboratory maximum dry
> density. The optimum moisture content is the moisture content that
> corresponds to the laboratory maximum dry density.
>
> When soils contain more than 50 percent gravel, the required
> percentage of the laboratory maximum dry density can be reduced. The
> required percent of laboratory maximum dry density will be determined
> directly from the appropriate curve in ASTM D 698-98 with no
> additional factors included therein.

excavating and placing operations shall be such that the materials, when
compacted, will be blended sufficiently to secure the highest
practicable density and highest shear strength. Water shall be added to
the materials as may be required to obtain the specified density by the
method of compaction being used.

> The thickness of the horizontal layers after compaction shall not be
> more than 6 inches if compaction is performed by hand or power tampers
> or rollers; not more than 12 inches if compaction is performed by
> treads of crawler‑type tractors, surface vibrators, or similar
> equipment; and not more than the penetrating depth of the vibrator if
> compaction is performed by internal vibrators.
>
> The relative density of the compacted material shall not be less than
> 70 percent as determined by ASTM D 4253-00 and D 4254-00.
>
> Relative density test. ‑ The relative density tests will be made by
> the Contracting Officer's Representative. The relative density of a
> cohesionless, free-draining soil is defined as its state of
> compactness with respect to the loosest and most compact states at
> which it can be placed by laboratory procedures described in ASTM
> D 4253-00 and D 4254-00. The relative density is determined by the
> following formula, wherein the maximum density is the highest density
> of the soil, minimum density is the lowest density of the soil, and
> in‑place density is the density of the minus 3‑inch fraction or
> portion of the soil in place. Tests for moisture content are made on
> the materials and the densities are expressed in terms of ovendry
> weights.

points dry of optimum moisture, the dry density of the soil fraction in
the compacted material shall not be less than 95 percent of the
laboratory maximum soil dry density, as determined by ASTM D 4253-00;
and that for materials being compacted that have a moisture content
between 2 and 4 percentage points dry of optimum moisture, the dry
density of the soil fraction in the compacted material shall not be less
than 98 percent of the laboratory maximum soil dry density, as
determined by ASTM D 4253-00.

\(b\) Dry density using the relative density test as prescribed in
subparagraph c(1)(a) above. ‑ The relative density of the compacted
material shall not be less than 70 percent as determined by ASTM
D 4253-00 and ASTM D 4254-00.

> Except as otherwise provided for moisture content in subparagraph
> c(2)(a) above, the materials shall be moistened, placed, and compacted
> in accordance with subparagraph b. above when density is determined by
> the laboratory compaction test. When density is determined by the
> relative density test, the materials shall be moistened, placed, and
> compacted in accordance with subparagraph c(1) above.

d\. In‑place densities. ‑ The in‑place density of the compacted material
in will be determined by one of the following: (1) the sand-cone method
(ASTM D 1556-00); (2) the sleeve method (ASTM D 4564-02); or (3) other

5.2.5 Batching, Mixing, and Transporting

Concrete shall be manufactured and delivered in accordance with ASTM C
94/C 94M-00e2, \"Standard Specifications for Ready‑Mixed Concrete.\"

When bulk cementitious materials and aggregates are dry batched and
hauled to where mixing is accomplished, each batch shall be protected
during transit to prevent loss and to limit prehydration of the
cementitious materials. Separate compartments with suitable covers shall
be provided to protect the cementitious materials or they shall be
completely enfolded in and covered by the aggregates to prevent wind
loss. If cementitious materials are enfolded in moist aggregates or
otherwise exposed to moisture and delays occur between batching and
mixing, the Contractor shall, at the Contractor\'s expense, add extra
cementitious materials to each batch in accordance with the schedule in
table 5A.

Table 5A. ‑ Additional cementitious materials requirements

+------------------------------------+---------------------------------+
| Hours of contact between           | Additional cementitious         |

+------------------------------------+---------------------------------+

The Government reserves the right to require the addition of
cementitious materials for shorter periods of contact during periods of
hot weather and the Contractor shall be entitled to no additional
compensation by reason of the shortened period of contact.

When delivered at the jobsite, each batch of concrete shall be
accompanied by a batch ticket in accordance with ASTM C 94/C 94M-00e2.
The batch ticket shall be delivered to the Contracting Officer's
Representative at the jobsite as each batch is delivered.

5.2.6 Forms, Preparation for Placing, and Placing

Forms shall be cleaned and oiled using form oil prior to each placement.
Forms shall be sufficiently tight to prevent loss of mortar from the
concrete and shall be maintained rigidly in position until the concrete
has hardened sufficiently to prevent damage by form removal. All
surfaces of foundations upon or against which concrete is to be placed
shall be free from standing water, mud, and debris. Rock surfaces shall
be free from oil, objectionable coatings, and loose, semidetached, and
unsound fragments. Immediately prior to placement of concrete, surfaces
of rock shall be washed with an air‑water jet and shall be brought to a
uniform surface‑dry condition. Earth foundations shall be free from
frost or ice when concrete is placed upon or against them. The surfaces
of absorptive foundations against which concrete is to be placed shall
be moistened thoroughly so that moisture will not be drawn from the
freshly placed concrete. The surfaces of construction joints shall be
clean, rough, and surface dry when covered with fresh concrete. Cleaning
shall consist of the removal of laitance, loose or defective concrete,
coatings, sand, curing compound, and other foreign material. The
surfaces of the construction joints shall be wet sandblasted or
bushhammered and washed thoroughly prior to the placement of adjoining
concrete , provided the sandblasting or bushhammering is preformed at
the latest practical time. Just prior to placement of concrete the
construction joint shall be washed thoroughly and dried to a saturated
surface dry condition. A mortar layer shall not be used on concrete
construction joints.

The methods and equipment used for transporting concrete, and the time
that elapses during transportation shall be such as will not cause
appreciable segregation of concrete ingredients or slump loss in excess
of 2 inches in the concrete as it is delivered to the work. Aluminum
pipes and chutes shall not be used for placing of concrete or for the
delivery of pumped concrete. Retempering of concrete will not be
permitted. Any concrete which has become so stiff that proper placing
cannot be assured shall not be used. Concrete shall be placed in
accordance with these specifications and American Concrete Institute
(ACI) Standard 306R-88, Cold Weather Concreting. The temperature of the
concrete during placement shall be between 50^o^F and 90^o^F and shall
comply with ACI 306 R-88.

Formed concrete shall be placed in continuous, approximately horizontal
layers, the depths of which generally shall not exceed 20 inches.
Concrete shall be vibrated until it has been consolidated to the maximum
practicable density, is free from pockets of coarse aggregate, and
closes snugly against all surfaces of forms and embedded materials.

5.2.7 Structural Deviations and Surface Tolerances for Concrete
Construction

a\. General. ‑ Structural deviations are defined as allowable variations
from specified lines, grades, and dimensions. Allowable variations from
specified lines, grades, and dimensions are listed in table 5B in
subparagraph b. below. Surface tolerances are the maximum allowable
magnitude of the surface irregularities. Allowable magnitudes for
concrete surface irregularities are specified in table 5C in
subparagraph d. below.

> The intent of this paragraph is to establish structural deviations and
> surface tolerances that are consistent with modern construction
> practice, yet are governed by the effect that permissible variations
> may have upon a structure. The Government reserves the right to
> diminish the structural deviations and/or surface tolerances set forth
> herein if such variations impair the structural action, operational
> function, or architectural appearance of a structure or portion
> thereof.
>
> Concrete shall be within all stated variations even though more than
> one may be specified for a particular concrete structure. The
> specified variation for one element of a structure shall not apply
> when it will permit another element of the structure to exceed its
> allowable variation. Where variations are not specified or shown on
> the drawings for a particular structure, variations shall be those
> specified for similar work. Specific tolerances shown on the drawings
> in connection with any dimension shall govern over general tolerances
> specified herein. The Contractor shall be responsible for finishing
> the concrete and for setting and maintaining concrete forms within the
> limits necessary to ensure that the completed work will be within the
> variations specified. Concrete work that does not conform to the
> limits specified shall be remedied in accordance with subparagraphs d.
> and e. below.

b\. Structural deviations. ‑ Variations from specified lines, grades,
and dimensions in hardened concrete structures shall be checked by the
Contractor and will be subject to such inspection and measurement as
needed to determine that the structures are within the tolerances
specified in individual delivery orders.

> Variation is defined as the distance between the actual position of
> the structure or any element of the structure and the specified
> position in plan for the structure or the particular element. Plus or
> minus variations, shown as plus (+) or minus (‑), indicate a permitted
> actual position up or down and in or out from the specified position
> in plan. Variations not designated as (+) or (‑) indicate the maximum
> deviation permitted between designated successive points on the
> completed element of construction.
>
> Specified position in plan is defined as the lines, grades, and
> dimensions described in the individual delivery orders or as otherwise
> prescribed by the Contracting Officer.

c\. Concrete surface irregularities.

\(1\) General. ‑ Bulges, depressions, and offsets are defined as
concrete surface irregularities (or roughness). Concrete surface
irregularities are classified as \"abrupt\" or \"gradual\" and allowable
tolerances are listed in table 5C. A concrete surface tolerance is
designated by a capital \"T\" followed by a number 1 through 5. Concrete
surface tolerance designations are separate from concrete surface
finishes and concrete structural deviations.

\(2\) Abrupt surface irregularities. ‑ Abrupt surface irregularities are
defined herein as offsets such as those caused by misplaced or loose
forms. Abrupt surface irregularities are further defined as isolated
irregularities in which the maximum dimension of the irregularity
perpendicular to the surface is greater than the maximum dimension of
the irregularity in the plane of the surface. Also, abrupt surface
irregularities include all incidences of isolated surface irregularities
which exceed the gradual irregularity specifications set forth herein.
Abrupt surface irregularities are measured as specified in
subparagraph f. below.

\(3\) Gradual surface irregularities. ‑ Gradual surface irregularities
are defined herein as bulges and depressions resulting in gradual
changes on the concrete surface. Gradual surface irregularities are
further defined as isolated undulations on the concrete surface. The
maximum dimension of the undulation perpendicular to the surface is
small relative to the maximum dimension of the undulation in the plane
of the surface. Gradual surface irregularities are measured as specified
in subparagraph f. below.

\(4\) The magnitude of surface irregularities of formwork and finished
concrete surfaces shall be checked by the Contractor to ensure that the
concrete surfaces are within specified tolerances. The Government will
also make such checks of hardened concrete surfaces as determined
necessary to ensure compliance with these specifications.

d\. Concrete surface tolerances.

Table 5B. ‑ Concrete surface tolerances

+------------------------+-----------------+--------------------------+

e\. Repair of hardened concrete not within specified tolerances.
Hardened concrete which is not within specified tolerances shall be
repaired to bring it within those tolerances. Such repair shall be in
accordance with paragraph 5.3.12 and shall be accomplished in a manner
approved by the Contracting Officer. Concrete repair to bring concrete
within tolerances shall be done only after consultation with a
Government inspector regarding the method of repair. The Contractor
shall notify the Government as to the time when repair will be
performed.

> Concrete which will be exposed to public view shall be repaired in a
> manner which will result in a concrete surface with a uniform
> appearance. Grinding of concrete surfaces exposed to view shall be
> limited in depth such that no aggregate particles are exposed more
> than 1/16 inch in cross section at the finished surface. Where
> grinding has caused or will cause exposure of aggregate particles
> greater than 1/16 inch in cross section at the finished surface,
> concrete shall be repaired by excavating and replacing the concrete.

f\. Field verification of concrete surface tolerances. ‑ To determine
compliance of a concrete surface with the surface tolerance
specifications, the following evaluation and measuring techniques shall
be employed:

\(1\) Evaluating surface roughness. ‑ The following steps describe the

evaluation process for concrete surface roughness:

\(a\) Measure the roughness height or depth and check for compliance
with the values given in tables 5B. ‑

> (aa) If the measured height or depth of the roughness is less than the
> value given by the abrupt tolerance specification, and if the height
> or depth of the roughness does not cause the structure to exceed any
> applicable value specified in table 5B, then the surface roughness is
> acceptable and no further evaluation is required.
>
> (bb) If the roughness height or depth exceeds the abrupt tolerance
> specification, the roughness slope must be determined for comparison
> to the gradual tolerance specification.
>
> \(b\) Measure the roughness length and determine the roughness slope
> by dividing the roughness height or depth by the roughness length (see
> figure 1 for details).
>
> (aa) If the roughness slope is greater than the slope specified by the
> gradual tolerance specification, then the roughness does not meet the
> specifications and shall be repaired by and at the expense of the
> Contractor.
>
> (bb) If the roughness slope is less than the gradual slope specified
> and if the gradual roughness does not cause the structure to exceed
> allowable structural deviations, as specified in table 5B, the
> roughness is acceptable.

height="7.834722222222222in"}

> \(2\) Measuring surface roughness. ‑ Two examples, illustrating how to
> make the necessary surface measurements for typical roughness, are
> given below:
>
> \(a\) Case 1. ‑ Roughness protruding above the surface. ‑ A roughness
> protruding above the surface should be measured with a straightedge
> that is at least 20 times longer than the roughness height being
> measured. Position the straightedge with one end resting on top of the
> roughness, as shown in figure 2 (case 1). Determine the roughness
> height by measuring the maximum gap that occurs normal to the straight
> edge. Also, note the position on the straightedge from which the
> normal distance is measured. To determine the roughness length,
> measure the distance along the straightedge from the point where the
> height was measured to the point of contact between the straightedge
> and the top of the roughness. The roughness slope is defined as the
> ratio of the roughness height to the roughness length. As roughness is
> seldom symmetric, moving the position of the straightedge about the
> roughness may be necessary to locate the point where the maximum
> height and slope exists.
>
> \(b\) Case 2. ‑ Roughness extending below the surface. ‑ A roughness
> occurring as an indentation to the surface is measured by placing the
> straightedge across the indentation, as shown in figure 2 (case 2).
> Measure the maximum gap between the straightedge and the surface and
> note the location of the measurement on the straightedge. From the
> point of the depth measurement, measure along the straightedge in both
> directions to the point of contact with the surface. The shortest
> length measured is used as the roughness length. Divide the roughness
> depth by the roughness length to determine the roughness slope.
>
> A simple measuring device can be constructed to perform the surface
> tolerance measurements and evaluation process directly and quickly.
> Information concerning concrete tolerance measuring devices can be
> obtained from the Bureau of Reclamation, Attn. D‑8180, PO Box 25007,
> Denver CO 80225, telephone (303) 236‑3730, extension 404.

g\. Prevention of repeated failure to meet tolerances. ‑ When concrete
placements result in hardened concrete that does not meet specified
tolerances, the Contractor shall, upon request, submit to the Government
an outline of all preventive actions, such as modifications to forms,
modified procedure for setting screeds, and different finishing
techniques, to be implemented by the Contractor to avoid repeated
failures. The Government reserves the right to delay concrete placements
until the Contractor implements preventive actions which have been
approved by the Contracting Officer.

5.2.8 Reinforcement

a\. Steel reinforcing bars shall be placed as prescribed by individual
delivery orders. Before being placed, surfaces on reinforcement shall be
cleaned of heavy, flaky rust; loose mill scale; dirt; grease; and other
foreign substances. Reinforcement shall be placed to meet the following
tolerances:

\(1\) The amount of concrete cover protecting reinforcement shall not
deviate from that specified by more than 2 inches if the specified cover
is more than 2‑1/2 inches, nor by more than 3 inches if the cover
specified is 2‑1/2 inches or less.

\(2\) The spacing of reinforcing bars shall not deviate from the
required spacing by more than 1 inch.

> Reinforcement shall be accurately placed and secured in position so
> that it will not be displaced during the placing of the concrete.
> Welding or tack welding of grade 60 reinforcing bars will not be
> permitted except at locations shown on the drawings.
>
> Where portions of the reinforcement supports will be exposed to view
> on concrete surfaces, the exposed portion of the supports shall be
> galvanized or other corrosion‑resistant material, except that
> reinforcement supports made of concrete will not be permitted. Unless
> otherwise shown on the drawings, the reinforcement shall be placed so
> that there will be a clear distance of at least 1 inch between the
> reinforcement and anchor bolts, form ties, or other embedded
> metalwork.
>
> The Government will not furnish supplemental bar‑placing diagrams, bar
> lists, and bar‑bending diagrams. Supplemental diagrams and bar lists
> of this type which the Contractor may require to facilitate the
> fabrication and placement of reinforcement shall be provided by the
> Contractor. The cost of preparing supplemental diagrams and bar lists,
> if provided, shall be included in the unit price per pound offered in
> the schedule for furnishing
>
> and placing the reinforcement or in the items of the schedule which
>
> include the concrete in which the reinforcement is used. Reinforcement
> will be inspected for compliance with requirements as to size, shape,
> length, splicing, position, and amount after it has been placed.
>
> The Contractor shall prepare and submit to the Government, for
> approval, reinforcement detail drawings for all structures, including
> bar‑placing drawings, bar‑bending diagrams, and bar lists.
> Reinforcement detail drawings shall follow the recommendations
> established by the American Concrete Institute\'s \"Manual of
> Engineering and Placing Drawings for Reinforced Concrete Structures\"
> (ACI 315 R‑94) and shall otherwise conform to the requirements shown
> on standard drawing 40‑D‑6263.

b\. Installing dowel bars. - Where shown on the drawings, holes shall be
core drilled into the existing concrete to receive dowel bars for
anchoring new concrete to existing concrete. The dowel bars shall be
grouted in place with epoxy resin grout. The Contractor shall furnish
all materials. The dimensions of the dowel bars and the locations,
diameters, and depths of the reinforcing bar holes shall be as shown on
the drawings or as directed. The diameter of each hole shall not be less
than 1‑1/2 times the diameter of the dowel bar specified for that hole.

\(1\) Materials.

\(a\) Epoxy grout. ‑ The epoxy resin grout shall conform to ASTM C 881/C
881M-02, type I.

\(b\) Dowel bars. ‑ Dowel bars shall be in accordance with paragraph
5.3.3.

> Dowel bars shall be cleaned thoroughly before being placed. Bars shall
> be cut to the lengths shown and bent to the proper shape prior to
> grouting in place. The holes shall be core drilled to proper depth and
> thoroughly blown clean. Placement of grout and bars shall be in
> accordance with the grout manufacturer\'s instructions. The surface of
> the existing concrete to which the new concrete is to be bonded shall
> be prepared as a construction joint in accordance with paragraphs
> 5.3.6 and 5.4.1.

c\. Cost. ‑ All costs of furnishing and installing reinforcement, core
drilling holes for dowel bars, furnishing epoxy grout, and grouting bars
in place shall be included in the negotiated proposal offered in the
schedule for concrete.

5.2.9 Finishes and Finishing

a\. General. ‑ The classes of finish and the requirements for finishing
of concrete surfaces shall be as specified in this paragraph, and tables
5D and 5E of paragraph 5.3.11 or as otherwise required by individual
delivery orders. Where finishes are not specified or shown on the
drawings for a particular structure or surface, the finish shall be as
specified for similar work. The Contractor shall notify the Contracting
Officer before finishing concrete. Unless inspection is waived in each
specific case, finishing of concrete shall be performed only when a
Government inspector is present.

> Concrete surface variations will be measured by the Government in
> accordance with paragraph 5.3.7 where necessary to verify that
> concrete surfaces are within the specified tolerances. Finished
> concrete which is not within the specified tolerances shall be
> repaired in accordance with paragraph 5.3.12.

b\. Formed surfaces. ‑ The classes of finish for formed concrete
surfaces are designated by the symbols F1 and F2. The classes of finish
shall apply as follows:

\(1\) F1. ‑ Finish F1 generally applies to formed surfaces upon or
against which fill material, grout, or concrete is to be placed. Form
tie rod ends on surfaces which will be in contact with fill material
shall be protected from moisture if they will be below the water table
or water line. Protection shall consist of recessing the tie rod ends
and filling the recesses with dry pack or other approved material or by
a waterproofing system approved by the Contracting Officer. Form tie rod
ends on surfaces which will be in contact with concrete or form tie rod
ends on surfaces which will be in contact with fill material but will be
above the maximum water table elevation may be cut off flush with the
formed surfaces or may be recessed without filling.

\(2\) F2. ‑ Finish F2 generally applies to all formed surfaces not
permanently concealed by fill material, grout, or concrete.

c\. Unformed surfaces. ‑ The classes of finish for unformed concrete
surfaces are designated by the symbols U1 and U2. Interior surfaces
shall be sloped for drainage where shown on the drawings or directed.
Surfaces which will be exposed to the weather and which would normally
be level shall be sloped for drainage. Unless the use of other slopes or
level surfaces is indicated on the drawings or directed, narrow
surfaces, such as tops of walls, shall be sloped approximately
three‑eighths inch per foot of width; and broader surfaces, such as
platforms and decks, shall be sloped approximately one‑fourth inch per
foot.

Unless otherwise specified or indicated on the drawings, these classes
of finish

shall apply as follows:

\(1\) U1. ‑ Finish U1 (screeded finish) generally applies to unformed
surfaces that will be covered by fill material, grout, or concrete.
Finish U1 is also used as the first stage of finishes U2 and U3.
Finishing operations shall consist of sufficient leveling and screeding
to produce even uniform surfaces.

\(2\) U2. ‑ Finish U2 (floated finish) generally applies to unformed
surfaces not permanently concealed by fill material, grout, or concrete.

> Floating may be performed by use of hand‑ or power‑driven equipment.
> Floating shall be started as soon as the screeded surface has
> stiffened sufficiently, but before bleed water forms, and shall be the
> minimum necessary to produce a surface that is free of screed marks
> and is uniform in texture.
>
> After surfaces have been finished by wood floating, the surfaces shall
> be given a broom finish. The finish shall be applied when the water
> sheen has practically disappeared. The broom shall be drawn
> transversely across the pavement with adjacent strokes slightly
> overlapping. The brooming shall be completed before the concrete is in
> such condition that the surface will be torn or unduly roughened by
> the operation. Brooms shall be of a quality, size, and construction,
> and be so operated, as to produce a surface finish satisfactory to the
> Contracting Officers Representative.

5.2.10 Protection and Curing

The Contractor shall protect all concrete against injury until final
acceptance by the Government. Concrete shall be protected against
freezing temperatures by being kept at a temperature not lower than
50^o^F for at least 72 hours after it is placed. In addition, concrete
which is water cured shall be protected against freezing temperatures
for the duration of the curing period. Then after discontinuance of the
water curing, this concrete shall be maintained above freezing for the
next 72 hours. Where artificial heat is employed, special care shall be
taken to vent the heater and to prevent the concrete from drying.

Minor surface repair, if needed, shall be completed within 2 hours after
form removal and shall be immediately followed by the initiation of
curing. As soon as unformed concrete surfaces have been finished, as
specified and have attained a dull appearance free from bleed water and
moist sheen, they shall be cured as specified herein. Where curing
compound is to be applied, formed concrete surfaces shall be kept
continuously moist by repeated light spraying with water until
immediately prior to application of curing compound. Curing compound
shall be applied as soon as the surface film of moisture has
disappeared, but while the concrete still as a damp

appearance.

Concrete and concrete‑curing compound shall be protected against heavy
foot traffic and other construction activities by covering with plywood,
sand, or other suitable material. After the danger of damage has
diminished, the Contractor shall remove and dispose of such covering and
all other foreign materials as directed by the Contracting Officers
Representative.

Concrete shall be cured with water, polyethylene film, or white
pigmented wax‑base or white pigmented water‑emulsified, resin‑base
curing compound. Surfaces of construction joints, surfaces on which
mortar is to be placed, and surfaces of concrete upon which equipment or
metalwork will be grouted in place shall be cleaned thoroughly of all
curing compound by wet sandblasting or bushhammering prior to placing
concrete, mortar, or grout against these surfaces.

Concrete cured with water shall be kept wet for at least 14 days from
the time the concrete has attained sufficient set to prevent detrimental
effects to the concrete surfaces. The concrete surfaces to be cured
shall be kept wet by covering them with water‑saturated material; by
using a system of perforated pipes, mechanical sprinklers, or porous
hose; or by other methods which will keep all surfaces continuously (not
periodically) wet. All curing methods are subject to approval by the
Contracting Officers Representative.

Curing with wax‑base or water‑emulsified, resin‑base compound shall be
by application to designated concrete surfaces to provide a
water‑retaining film. The curing compound shall be reapplied as
necessary to maintain a continuous, water‑retaining film on the surfaces
for 28 days. The curing compound shall be mixed thoroughly and applied
in accordance with the manufactor's recommendations to the concrete
surfaces in one coat to provide a continuous, uniform film over the
concrete. The coverage rate shall not exceed 150 square feet per gallon
(3.7 square meters per liter) for wax-base or water‑emulsified,
resin‑base curing compound and 200 square feet per gallon (4.9 square
meters per liter) for clear resin‑base compound. On rough surfaces, the
coverage rate shall be decreased as necessary to obtain the required
continuous film. Special care shall be taken to ensure ample coverage
with the compound at edges, corners, and rough surfaces; and to keep
curing compound off waterstops and reinforcing bars.

In applying clear resin‑base curing compound, care shall be taken to
produce a uniform, continuous film, and to avoid sagging and puddling of
liquid compound and excessive, unsightly thickness. To prevent sagging
of compound on surfaces which are not horizontal, application shall
consist of two or more passes over each point on the surface using a
cross‑spraying technique, and with a time interval between passes not
exceeding 30 minutes.

Spray equipment and its performance will be subject to approval; and
when so directed, the Contractor shall repair or replace equipment as
required to make it acceptable to the Contracting Officer. The
application shall be performed by personnel qualified, as determined by
the Contracting Officers Representative, in using the specified spray
techniques.

Curing with polyethylene film shall be by completely covering the
designated concrete surfaces with polyethylene film to provide an
airtight, water‑retaining film over the entire concrete surface for at
least 14 days. As soon as the concrete has hardened sufficiently to
prevent damage, all surfaces shall be thoroughly moistened by spraying
them lightly with water and then covering them completely with the
polyethylene film. Edges of the polyethylene strips shall be lapped to
effect a seal to adjacent strips and, at the extreme edge of the curing
area, held tightly against the concrete surface. The polyethylene film
shall be secured adequately to withstand wind and to prevent circulation
of air inside the curing film.

5.2.11 Finish, Surface Tolerances, and Curing Schedule

The type of concrete finish, surface tolerance, and curing method shall
be as specified in tables 5D and 5E below. Allowable tolerances are
specified in table 5C of paragraph 5.3.7. Structural variations shall be
in accordance with paragraph 5.3.7.

SECTION 5.3. - SPECIAL CONCRETE REQUIREMENTS

5.3.1 Joints and Edges in Concrete

a\. Construction joints. ‑ Construction joints are joints which are
purposely placed in concrete to facilitate construction; to reduce
initial shrinkage stresses and cracks; to allow time for the
installation of embedded metalwork; or to allow for the subsequent
placing of other concrete. Bond is required at construction joints
regardless of whether or not reinforcement is continuous across the
joint.

> The location of all construction joints in concrete work shall be
> subject to approval of the Contracting Officer's Representative, and
> the joints shall be constructed in accordance with paragraph 5.2.6.

b\. Expansion joints. ‑ Expansion joints shall be constructed at the
locations indicated by individual delivery orders. Joint filler shall be
placed in all expansion joints of the type and size indicated by
individual delivery orders. The joint filler shall cover the entire
surface of the concrete at each joint, and shall be laid against the
concrete and held rigidly in place while the concrete is placed on the
other side of each joint. All joints in the joint filler shall be
tightfitting butt joints.

c\. Materials for joints shall be as follows:

> Sealant shall be mixed and applied in strict accordance with the
> manufacturer\'s instructions, a copy of which will be provided to the
> on site Government inspector. Sealant may be placed in the joint
> grooves as soon as the concrete has cured sufficiently to allow
> necessary foot traffic without damage to the concrete. Immediately
> before placing sealant in the joint grooves or over random cracks, the
> surface to receive the sealant shall be thoroughly cleaned by approved
> methods to remove all mortar, laitance, scale, dirt, oil, curing
> compound, and other foreign materials. Where curing compound has been
> applied to the surfaces to receive the sealant, the surfaces upon and
> against which the sealant is to be placed shall be sandblasted. The
> surfaces that have been sandblasted, and other surfaces where
> directed, shall be cleaned with high-pressure compressed air to
>
> remove all residue. The Contractor shall be responsible for providing
> oil-free compressed air. Elastomeric sealant shall not be placed while
> rain or snow is falling.
>
> At the time of placing the joint sealant, the surface shall be clean
> and dry and the temperature of the concrete and the ambient
> temperature shall be not less than 50^o^F.
>
> Sealant will be unacceptable if gassing, foaming, bubbling, or
> blistering occurs in the sealant as a result of high ambient
> temperatures, high concrete surface temperatures, or from other
> causes. Use of unacceptable sealant shall be immediately discontinued
> until otherwise directed by the Contracting Officer, and all
> unacceptable sealant shall be removed and replaced. The cost of
> delays, removal, and replacement of unacceptable sealant shall be the
> responsibility of the Contractor.
>
> When placed in grooves, the sealant shall be extruded at the bottom of
> the joint groove. Nonsag sealant shall be tooled as necessary to work
> the sealant into intimate contact with the bonding surfaces without
> entrapping air bubbles. The top surface of the sealant shall be tooled
> to the shape in individual delivery orders. When placed as a cap seal,
> the center of the cap shall follow closely over the random crack to
> provide maximum thickness of sealant directly over the crack.
> Application equipment configuration and tooling shall be capable of
> providing and maintaining the sealant in the shape shown on the
> drawings until the sealant has cured.
>
> Elastomeric sealant which does not cure to a homogeneous, rubberlike
> compound or which does not bond to the joint groove or other required
> surfaces or which does not comply with an other requirements of this
> paragraph shall be removed. The joint groove or surface to be capped
> shall then be recleaned by an approved method and new sealant placed
> therein by the Contractor at no additional cost to the Government.
>
> Sealant pulled out of joints or damaged by the Contractor's
> operations, or otherwise damaged during the contract period, shall be
> replaced in accordance with the applicable provisions of these
> specifications at no cost to the Government.

e\. Edges. ‑ The Contractor shall tool or chamfer edges of concrete
where shown on the drawings and elsewhere as required.

f\. Cost. ‑ The cost of furnishing all materials and performing all work
for constructing construction joints, contraction joints, and expansion
joints and for tooling or chamfering concrete edges shall be included in
the unit price offered in the negotiated schedule for the concrete for
which the joints or edges are required.

> The Contractor shall submit the manufacturer\'s certification for the
> PVC compound used for fabrication of the waterstop to be provided. The
> manufacturer\'s certification shall cover all material requirements of
> subparagraph b., and shall include all physical property test data on
> the compound used to fabricate the waterstop. These tests shall be
> performed by the manufacturer or other laboratory. The tests shall be
> conducted no more than 18 months prior to the submittal. The
> Contractor shall be responsible for the accuracy of the
> manufacturer\'s certification and the sampling certification.

5.3.2 Grouting Mortar for Equipment and Metalwork

a\. General. ‑ Nonsettling grouting mortar and grouting mortar shall be
furnished and placed as required by individual delivery orders and shall
be in accordance with this paragraph. Except where nonsettling grouting
mortar is indicated by individual delivery orders, the mortar used for
grouting shall be grouting mortar.

b\. Nonsettling grouting mortar. ‑ Unless inspection is waived in each
specific case, the weighing and preblending of the aluminum powder and
cement for the nonsettling grouting mortar and the mixing and placing of
the nonsettling grouting mortar shall be performed only in the presence
of the Government inspector.

> Nonsettling grouting mortar shall be composed of cement, water, sand,
> and aluminum powder. Cement shall be as specified in paragraph 5.2.3.
> Water and sand shall be in accordance with paragraph 5.2.3, except
> that sand passing a No. 16 screen shall be used when clearances are
> such that the specified grading for sand is not suitable. Aluminum
> powder for use in the mortar shall be ground; shall contain no
> polishing agents, such as stearates, palmitates, and fatty acids; and
> shall effectively produce the desired expansion.
>
> Mix proportions of the nonsettling grouting mortar shall be 1 part
> cement to 1‑1/2 parts sand, by weight, for a fluid mortar; and 1 part
> cement to 2 parts sand, by weight, for a plastic mortar; each
> containing a small amount of aluminum powder as specified below. The
> water‑cement ratio of the mortar shall not exceed 0.50, by weight, and
> the slump of the mortar shall be the lowest practicable for the space
> to be filled. The exact mix proportions and water‑cement ratio for the
> mortar will be determined by the Contracting Officer.
>
> The quantity of aluminum powder to be used in the mortar will be
> governed by the quantity and characteristics of the cement used, and
> will vary as the placing temperature varies, from about 2 grams of
> aluminum powder per bag of cement for 90 °F placing temperature to
> about 5 grams at 40 °F placing temperature. After weighing, the
> aluminum powder shall be thoroughly preblended with a small amount of
> 28ortland cement before adding to the grouting mortar. This preblended
> material shall be a uniform blend of 1 part aluminum powder to 50
> parts cement, by weight.

c\. Grouting mortar. -- Grouting mortar shall be composed of cement,
water, and sand. Cement shall be as specified in paragraph 5.2.3. Water
and sand shall be in accordance with paragraph 5.2.3, except that sand
passing a No. 16 screen shall be used when clearances are such that the
specified grading for sand is not suitable. Grouting mortar shall be
mixed in the proportion of 1 part of portland cement to 2‑1/2 parts of
sand, by weight, and to the consistency prescribed by the Contracting
Officer.

d\. Preparation of surfaces and placing mortar. ‑ Before placing mortar,
the surfaces of base concrete to which the mortar will be bonded shall
be roughened and shall be cleaned of all laitance, loose or defective
concrete, curing compound and other coatings, and other foreign material
by effective means, followed by thorough washing with water. If any
delay occurs between the washing of the concrete and placing of the
mortar, the surfaces of the concrete shall be lubricated by washing with
water immediately before placing of the mortar. Forms shall be used,
where required, to confine the nonsettling grouting mortar. The mortar
shall be placed, completely filling spaces adjacent to equipment and
metalwork as indicated by individual delivery orders.

Temperature requirements of placing grout shall be performed in
accordance with Paragraph 5.2.6.

e\. Curing. ‑ The exposed surfaces of mortar shall be cured for 72 hours
by keeping them covered with moist burlap, damp sand, or by other
effective means approved by the Contracting Officer. Temperatures while
curing grout shall be in accordance with paragraph. 5.2.10.

> Loads shall not be applied to the mortar sooner than 72 hours after
> placement and shall be applied only after the mortar has attained a
> compressive strength of at least 3,000 pounds per square inch. The
> time required for the mortars used to attain this strength will be
> determined by the Government. Care shall be taken when applying loads
> on the hardened mortar, and the Contractor shall be responsible for
> any damage thereto resulting from impact loads when positioning
> equipment or metalwork.

f\. Payment. -- Payment for all work in connection with placing mortar,
and the cost of the cement, aluminum powder, water, and sand for mortar
shall be included in the negotiated negotiated schedule offered in the
individual delivery orders for which the mortar is required.

5.3.3 [Shotcrete]{.underline}

a\. General. ‑ Shotcrete may be required to be placed by the Contractor,
which complies with paragraph 5.2.2 and this paragraph. Shotcrete is
defined as any pneumatically applied concrete or mortar placed directly
onto a surface. The shotcrete shall be composed of water, cementitious
materials, sand, coarse aggregate, and admixtures as specified by
individual delivery orders and shall be placed by the wet‑mix process as
specified herein.

> The compressive strength of the shotcrete shall be 600 pounds per
> square inch at 8 hours age, and 3,000 pounds per square inch at 28
> days age based on 3‑ by 3‑inch cores.
>
> Adjustments shall be made as directed by the Government to obtain
> shotcrete having suitable impermeability, density, strength, and
> durability. Suitable strength is that which will assure that 80
> percent of all test specimens exceed the design strength as specified
> above.
>
> The wet‑mix process shall consist of thoroughly mixing all the
> ingredients except the accelerator if used, feeding the mixture into
> the delivery equipment, delivering the mixture by positive
> displacement or compressed air to the nozzle, and then jetting the
> mixture from the nozzle at high velocity onto the surface to receive
> the shotcrete. The accelerator shall be added to the mixture at the
> nozzle.
>
> The equipment used by the Contractor for mixing and applying shotcrete
> shall be capable of handling and applying shotcrete containing the
> specified maximum size coarse aggregate and accelerating admixture, if
> used. All equipment, including mixers, hoses, nozzles, nozzle liners,
> air‑ and water‑pressure gauges, and gaskets, shall be maintained in
> clean and proper operating condition satisfactory to the Contracting
> Officer.

b\. Mix proportions. ‑ The proportions of water, cementitious materials,
sand, coarse aggregate, and admixture will be determined by the
Contractor subject to approval by the Contracting Officer to obtain the
specified compressive strength and placeability. The shotcrete will have
a minimum cementitious materials content of 658 pounds per cubic yard as
discharged from the nozzle. Furthermore, the amount of cementitious
materials will be increased by the Contracting Officer as necessary to
obtain the specified compressive strengths and bond.

c\. Consistency. ‑ The consistency of the wet‑mix process shotcrete, at
the delivery point, shall not exceed 3‑inch slump

d\. Tests. ‑ The Contractor shall obtain specimens for testing from
locations specified by the Government. The compressive strength of the
shotcrete will be determined by the Government through the medium of
tests of 3‑ by 3‑inch cores and 3‑inch cubes.

e\. The cementitious materials in shotcrete shall comply with paragraph
5.2.3.

f\. Admixtures. - The admixtures in shotcrete shall comply with
paragraph 5.2.3 with the following exceptions: accelerating admixtures
for shotcrete need not conform to the ASTM designations specified for
concrete but shall produce shotcrete meeting the specified strength and
bonding requirements of these specifications.

> The accelerating admixture shall not introduce more than 1/10 of 1
> percent chloride, by weight, of cementitious materials in shotcrete in
> which aluminum, galvanized metalwork, or prestressing steel is to be
> embedded. Moreover, the accelerating admixture shall not introduce
> more than 1 percent chloride, by weight, of cementitious materials in
> all other shotcrete.
>
> Liquid accelerator shall be protected from contamination and freezing
> until it is used in shotcrete. The liquid admixture shall be
> thoroughly remixed before use if there is any settlement or
> nonuniformity of the liquid.

Water‑reducing, set‑controlling admixtures may be used.

> The amount of air‑entraining admixture used for the wet‑mix process
> shall be that amount necessary to effect a total air content in the
> shotcrete, prior to application, of 7 percent plus or minus 1 percent
> by volume of shotcrete.

g\. Water. - Water used in making and curing shotcrete shall be in
accordance with the requirements of the individual delivery orders.

h\. Sand and coarse aggregate. - Except as hereinafter provided for
coarse aggregate, the sand and coarse aggregate shall be in accordance
with the requirements of the individual delivery orders.

> The nominal size coarse aggregate shall be three‑eighths inch. No
> significant oversize aggregate shall be permitted; that is, no
> material shall be retained on the 7/16‑inch test screen or sieve.
> There shall be no more than 3 percent significant undersize aggregate;
> that is, material which will pass a No. 5 United States Standard
> sieve.

i\. Prequalification of shotcrete and nozzlemen. - No shotcrete shall be
applied to the work until preconstruction testing indicates that the
nozzleman is qualified and the proposed shotcrete mixture meets the
specified compressive strength. The Contractor shall allow adequate lead
time for testing of shotcrete specimens. Furthermore, the Contractor is
encouraged to test several mixes since failure of a single mix to meet
specified strength requirements could delay accomplishment of other

> followed when applying all coatings and removing existing damaged
> coatings.

\(4\) Suspending of painting operations due to weather. ‑ If weather
conditions become unfavorable for coating application according to
manufacturer\'s recommendations or will become unfavorable for proper
cure of the applied paint, painting shall be suspended until conditions
are again favorable. If rust forms or the surfaces become otherwise
contaminated in the interval between cleaning and coating, or between
coats, recleaning shall be performed by the Contractor.

b\. Paint and coating materials approval.

\(1\) General. ‑ Prior to use or application of materials, the
Contractor shall submit to the Government, for approval, copies of
purchase orders, certifications, and/or samples of all coatings and
related materials, as specified herein. However, acceptance of the

d\. Preparation of surfaces.

\(1\) Metalwork and equipment. ‑ Surface preparation shall be in
accordance with the methods herein and as indicated in the coating
tabulation. Any coatings not required by and not shown in the coating
tabulation shall be removed from the surfaces by suitable and effective
means, unless otherwise directed. All surfaces not specifically covered
herein shall be prepared by methods common to good practice for the
particular surface. If rust forms or the surfaces become otherwise
contaminated in the interval between cleaning and coating, or between
coats, recleaning shall be performed by the Contractor.

\(a\) Initial surface preparation. ‑ Weld spatter, slag burrs, or other
objectionable surface irregularities shall be removed or repaired before
cleaning. Any contaminants to the coating, from cleaning operations or
other sources, shall be removed before the surfaces are coated.

> All oil and grease shall be removed from surfaces to be painted or
> coated by the use of clean solvent and clean, lint‑free wiping
> material. Cleaning solvent shall be a material which does not leave a
> residue, such as xylene. Cleaning cloths and solvents shall be
> discarded before they become contaminated to the extent that a greasy
> film would remain on the surface being cleaned.
>
> All applicable environmental and safety regulations shall be observed
> in handling the solvents and disposing of the cleaning
>
> cloths and excess solvents.

\(b\) Specific surface preparation. ‑ Following initial surface
preparation, specific surface preparation shall be by one of the
following methods, as specified for each item in the coating tabulation:

> Method C. ‑ Following the initial solvent cleaning, the surfaces shall
> be blast-cleaned to base metal, using dry, hard, sharp, blasting
> media, to produce a near‑white, abrasive-blasted surface free of all
> foreign substances to achieve the specified or recommended surface
> profile. The surface shall be cleaned to equal or exceed NACE No. 2 or
> SSPC‑SP10.

\(2\) Existing metalwork and equipment. ‑ Surface preparation of
existing metalwork and equipment shall be in accordance with this
subparagraph. Surfaces include those with sound but weathered coatings;
deteriorated and disbonded coatings; rusted galvanized and ferrous
metal; and deposits of grease, oil, and other foreign materials.
Cleaning methods employed shall create suitable surfaces for subsequent
coating and shall consist of methods specified in subparagraph d(1)
above, with modifications as follows:

> Prior to other cleaning, the surfaces shall be cleaned by pressure
> washing with clean, treated water (no detergent) or, where
> appropriate, by steam cleaning conforming to SSPC‑SP1, which shall
> include a detergent additive. The steam cleaning shall be followed by
> a hot‑water rinse or a second steam cleaning without the additive.
> Solvent cleaning shall also be used as necessary where pressure
> washing with clean, treated water (no detergent) has been used, or
> where inspection of the surface reveals a necessity for solvent
> cleaning.

e\. Application.

\(1\) Qualified applicators. - Coatings shall be applied only by
applicators whose qualifications have been submitted and approved in
accordance with subparagraph 8.1.1 b(2)(d).

(2) Materials shall be thoroughly mixed at the time of application, and
    shall be clean and free from moisture. The application of individual
    coating systems shall be applied within the specificized minimum
    curing temperatures and maximum application temperatures, and
    minimum and maximum relative humidities applicable to that coating
    system. The temperature and humidity limits shall be as defined on
    the coating category sheets or the product data sheets, whichever is
    more restrictive. Except as otherwise specified, coatings shall not
    be applied when the temperature of the item to be coated or of the
    surrounding air is under 45 EF. Application of approved, low
    temperature cure, coatings systems to surfaces, whose temperatures
    are at or below 40 EF, shall require that special precautions be
    taken against the deposition of coating over \"black ice.\"

> For metalwork items that are not being coated by single-component,
> moisture urethanes, and are not thoroughly dry at the time of coating
> application, shall be heated to a sufficient temperature (20- to
> 30-degrees above the dewpoint or 80 EF) to drive off any moisture
> present before the protective coating is applied. The surfaces to be
> coated shall be a minimum of 5 EF above the dewpoint at the time of
> coating application and during the full curing period. Coating shall
> proceed only when the humidity and the temperatures of atmosphere and
> of surfaces to be coated are such that evaporation rather than
> condensation will result. For some coating categories, condensation is
> not allowed at any time during the curing process. Application of
> these coatings shall not proceed until the proper curing environment
> can be maintained for the entire curing period between initial
> application and the next coat is applied or full cure has been
> obtained, whichever is shorter.
>
> For metalwork items that are being coated by single-component,
> moisture urethanes, the surfaces shall be free of \"black ice\"
> frozen, nor have any free moisture on the surface. Ideally, the
> coating shall proceed only when the humidity and the temperatures of
> atmosphere and of surfaces to be coated are such that evaporation
> rather than condensation will result. However, the coating may be
> applied when the surface is saturated, surface dry. In special cases
> the coating may be immersed within one hour of application, and
> between the addition of additional coats.
>
> As determined by the Contracting Officer, if necessary to improve
> application properties, cold‑applied coatings shall be heated by means
> of a hot‑water bath, or other OSHA‑approved method, to temperatures
> not exceeding 100 EF.
>
> Unless otherwise specified, priming (first) coats shall be applied
> using the following method:
>
> All boltheads, welds, edges, corners, and similar items shall be
> primed by brushing to thoroughly and effectively coat these difficult
> areas. The coating material may be delivered to the surface by
> spraying and then \"scrubbed in\" by brushing. If a thorough blowdown,
> vacuuming, or other dry means of cleaning the blasted surface has
> adequately removed remaining blasting debris, flat areas (without
> difficult areas) may be coated by spraying.
>
> Care shall be exercised during spray application to hold the nozzle
> sufficiently close to the surfaces being painted to produce a
> continuous wet coat, and to avoid excessive evaporation of the
> volatile constituents and loss of material into the air, or bridging
> over crevices and corners. Effective means shall be provided for
> removing free oil and moisture from the air‑supply lines of all
> spraying equipment. Spray equipment shall be equipped with pressure
> gauges, and pressure regulators. Spray equipment shall also be
> equipped with mechanical agitators, except when specific coating
> systems, i.e. single component, moisture cure, urethanes, require that
> mechanical agitators not be used. Nozzle pressure consistent with
> acceptable finish results shall be employed when spray coating.
>
> Each coat shall be applied in such a manner as to produce an even film
> of uniform thickness which will completely cover irregularities, fill
> crevices, and be tightly bonded to the substrate or previous coat.
> When registers and grilles are being coated, care shall be taken not
> to clog openings or otherwise excessively coat the surfaces. Each coat
> shall be free from runs, pinholes, sags, laps, brush marks, voids, and
> other defects. Each coat shall be allowed to dry or to harden before
> the succeeding coat is applied.
>
> Brush coats may be applied by the conventional brushing procedure, or
> the coating may be delivered to the surface in a fluid stream by means
> of spray equipment and the coating then spread immediately by brushing
> to a smooth, uniform coating.
>
> The thickness on steel surfaces shall be measured by approved gauges
> and shall be not less than the minimum specified thickness at any
> point on the coating. Acceptance will be based on specified coverages,
> or on the specified total dry‑film thickness (DFT) as measured by an
> Elcometer, Mikrotest, or other suitable DFT gauge after the complete
> coating system has hardened but before the recoating interval has been
> exceeded. Unless otherwise specified, the DFT is measured above any
> created profile on the surface, i.e., above the peaks, not the
> valleys, of the profile.
>
> Nonconductive coating applied to conductive base metals which will be
> buried or completely or partially submerged in water shall be tested
> for
>
> pinholes and holidays, using the following types of holiday detectors:
>
> \(a\) For coatings with a DFT of less than 16 mils, a low-voltage wet
> sponge holiday detector shall be used. No detergent shall be used when
> making the pinhole and holiday determination with a low-voltage wet
> sponge holiday detector.
>
> Minimum and maximum times for holiday detection and repair of pinholes
> and holidays shall be in accordance with the coating manufacturer\'s
> recommendations and these specifications. The Contractor shall notify
> the Contracting Officer's Representative 72 hours in advance of
> holiday testing so that the Contracting Officer's Representative may
> witness the pinhole and holiday testing.
>
> Thinning of coatings to facilitate satisfactory application shall be
> kept to a minimum, but in no event shall it exceed 1 pint per gallon
> of coating, except as otherwise specified; only thinner approved for
> the type of coating shall be used. The addition of thinner shall not
> cause the coating to exceed the VOC limits at the point of
> application.
>
> All Contractor‑applied coatings exposed to public view shall present a
> uniform texture and color‑matched appearance.
>
> Methods of preparing and applying paints and coatings not included in
> these specifications shall be in accordance with the manufacturer\'s
> instructions and the general requirements of these specifications.

\(3\) Application of specific materials shall be as follows:

> \(a\) Single-Component, moisture curing, urethane. - Application shall
> be in accordance with the manufacturer\'s recommendations. During
> coating application, do not exceed the maximum DFT or wet film
> thickness per coat listed in either the coating categories or coating
> tabulation. When applying the zinc‑rich urethane primers, it is better
> to have the applied coating thickness be closer to the minimum DFT,
> rather than toward the maximum DFT when applying the coating at
> elevated temperatures, greater than 90^o^ F, and or higher humidities,
> greater than 90 percent.
>
> \(b\) These urethanes react with atmospheric moisture. The applicator
> shall limit the time partially filled containers are open to the
> atmosphere before being resealed. Only open the new containers when
> ready to apply the coating. Do not open and then agitate or box mix
> the coating when the atmospheric or material temperatures are less
> than 5^o^ F above the dewpoint temperature. If the remaining coating
> in an open or resealed, partially full container will not be applied
> within two hours \"
>
> one hour, a four ounce per five gallon container, \"float\" of
> manufacture approved thinner shall be \"floated\" on the surface of
> the remaining
>
> coating in the container. Only use manufacture approved thinners.
> Other thinners may contain small quantities of moisture, alcohol, or
> other hydroxyl bearing solvents, which can destroy the moisture‑cure
> reaction either partially or completely without any outward change in
> appearance, color, viscosity, or gelling.
>
> \(c\) When using spray application equipment, do not continue to
> mechanically agitate the coating after the initial mixing.
