SECTION 13122

PRE-ENGINEERED BUILDING FOUNDATION PROCEDURES

[PART 1: GENERAL]{.underline}

1.1 SUMMARY:

A. ab Section Includes: When the pre‑engineered building furnished is
the \[[ ]{.underline}\] building specified and shown on the drawings,
the foundation shall be constructed as shown and no design is required.
When any other building is furnished, the Contractor shall design the
necessary foundations for such building in accordance with this
specification.

1.2 SYSTEM DESCRIPTION:

A. General: All footings and other sub-structure elements shall be
designed using the load and reaction data provided by the building
manufacturer\'s engineering department. Loads and reactions used shall
also reflect the results of analysis to incorporate local snow, wind and
seismic conditions into the design. The following values shall be the
minimum used:

1\. Snow Load - \[\_\_\_\_\_\] lb. per square foot.

2\. Wind Load - As produced by a \"Basic Wind Speed\" of \[\_\_\_\_\_\]
mph

3\. Seismic Load - Zone \[\_\_\_\_\_\].

B. Design Code Requirements:

1\. abBuilding Codes: Uniform Building Code by ICBO, 1988

2\. abAmerican Concrete Institute:

ACI 301‑89 Structural Concrete for Buildings

ACI 302.1R‑80 Guide for Concrete Floor and Slab Construction

ACI 318‑83 Building Code Requirements for Reinforced Concrete

3\. abAmerican Society for Testing and Materials:

ASTM D698-78 Moisture Density Relations for Soils and Soil-Aggregate
Mixtures

ASTM A307-90 Carbon Steel Bolts and Studs

C. Subsurface Conditions:

\[The design shall be in accordance with the subsurface conditions and
design criteria recommended in the geotechnic report entitled
\[\_\_\_\_\_\_\_\_\_\_\] prepared by
\[\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\]
which is available from the Contracting Officer.\] The design shall be
in accordance with the following criteria:

1\. ab Soil Bearing Pressure - \[\_\_\_\_\_\] psf

2\. Backfill (Against Foundation) - \[\_\_\_\_\_\] % maximum, dry
density, ASTM D698

3\. ab Lateral Force on Retaining Walls - \[30\] pcf equivalent fluid
pressure

\[\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\] -
\[\_\_\_\_\_\]\]\].

4\. \[All criteria used in the design shall be cited in the
computations. This citation shall give the source of the criteria and
provide justification for its use in the design.\] \[All assumptions
used shall be clearly represented as such.\]

5\. Design Requirements: Shall be designed utilizing the metal building
manufacturer\'s frame reaction data and shall conform to the area and
the shape as required for forces to be resisted.

6\. Reinforcing: Shall be a two way mat of reinforcing steel bars placed
in all footings allowing 3 inch clearances to footing bottoms and edges.
Properly anchor the vertical pier dowel reinforcement.

7\. Footing Concrete: Shall be placed on an engineered fill, cemented
soils or gravel at or below the depth indicated on the drawings. Provide
temporary drainage of ground water when required.

D. Column Piers:

1\. Column Piers: Shall be the necessary size and shape with necessary
reinforcing as required for forces to be resisted, the size of metal
column or rigid frame base plate.

2\. Vertical Pier Reinforcing: Shall be tied to footing reinforcing and
spandrel wall or grade beam.

E. Pier Footings:

1\. Reinforcing: Shall be a two way mat of reinforcing steel bars placed
in all footings allowing 3 inch clearances to footing bottoms and edges.
Properly anchor the vertical pier reinforcement into the footing.

2\. The top of spread footing shall be at the following minimum depths
below local grade:

Interior Footings - \[1 1/2 foot\]

\[All footings shall at sufficient depth to resist uplift forces.\]

F. Grade Walls or Grade Beams:

1\. Shall be a minimum of 8 inches in thickness.

2\. Shall include reinforcement in two layers.

3\. Shall be designed to participate in resisting building loads
including uplift.

G. Tie Rods:

1\. Reinforcing Bars: The horizontal frame thrust shall be resisted by
reinforcing bars extended from one pier to the opposite pier under the
floor. Size of bar shall be as required for the forces to be resisted
for the building height and span shown on the drawings. Contractor shall
encase all tie rods in concrete. Splices shall be an approved weld.

2\. Threaded Rods and Turnbuckles: May \[not\] be used in lieu of
reinforcing tie rods. \[Size of the rod or turnbuckle shall be the metal

according to the requirements of this specification section. Design
computations shall be prepared by and bear the stamp of a registered
professional engineer.

C. Design Drawings: Submit \[[ ]{.underline}\] copies of design drawings
for structural foundations, footings, piers, slabs, grade beams and
other walls to be used on this project. Drawings shall be prepared by
and bear the stamp of a registered professional engineer. Drawings shall
