Fontenelle Building Floor Slab

January 2009

# Prepared by: US Bureau of Reclamation

# Fontenelle Building Concrete Floor

## THE LOCATION

The construction work will be at Fontanelle Dam government housing area,
Fontenelle, Wyoming.

## GOVERNMENT CONTACT

The Government contact at the site is Chuck Green, phone number
307-877-3561.

## THE REQUIREMENT

Furnish concrete, form, place and cure a concrete floor in a newly
constructed building. The concrete floor covers an area of 100-feet by
120-feet. The floor will be reinforced concrete, a minimum of 6-inches
in thickness.

The buildings footings, bond beams and walls are already in place. The
walls have insulation installed, not interior steel wall panels. The
steel wall panels will be installed after the floor slab has been
placed.

The subgrade for placement of the floor will be graded and compacted by
the Government prior to arrival by the Contractor.

The Contractor shall set all grades of the forms, to set the slope of
the floor to drain to the center trench drain. Acceptable deviation from
grade is +/- 3/8-inch over a 20-foot length and +/- ¾-inch over more
than 40-feet length.

Place all expansion joint material around perimeter of building prior to
concrete placement. Protect roofing felt placed over bond beams from
movement and damage.

The concrete shall not be delivered until areas are ready for placement.

Provide concrete pumping, if truck placement is not possible.

Construction work will be performed during the spring months, with
access experiencing possible snow and freezing temperatures. The
building will be heated for placement of the floor. Concrete temperature
at placement shall be between 50 degrees F and 90 degrees F.

Finishing shall be done with power trowels to provide a smooth finish.
There shall not be any abrupt high or low spots within the finished
area.

Apply curing compound over the area. The curing compound shall meet ASTM
C309. Reapply as necessary to maintain a continuous, water-retaining
film on surface for 28 days.

Protect concrete against damage until final acceptance.

Protect concrete from damage by freezing. Maintain concrete above 50
degrees for at least 72 hours after placement. If artificial heat is
used, vent the heater and keep concrete from drying.

Within 12 hours of placement of concrete cut expansion joint to a depth
of 1/3 the concrete thickness with a concrete saw.

If concrete becomes damaged, repair using USBR M-47.

## CONCRETE REQUIREMENTS

Concrete -- 4,000 psi at 28 days, minimum compressive strength. See
Attachment A.

## GOVERNMENT ITEMS

The government will provide the following:

Grading, leveling and compaction of the subgrade.

Expansion board and roofing felt.

Trench drain material and installation.

Reinforcement will be furnished and installed by Government crews. The
Contractor shall coordinate with the Government on reinforcement
installation to correspond with the concrete placement. Government will
install roofing felt over the bond beams prior to placement of rebar.

Lighting of the building.

Heating of the building.

Water for cleanup of concrete equipment.

Wash down area for cleanup of concrete equipment.

## CLEANUP

The Contractor shall cleanup any splashed concrete from building doors
and columns surfaces to obtain a clean condition with not visible
material showing.

## GENERAL REQUIREMENTS

### Safety

Personnel shall adhere to Reclamation's Safety and Health Standards
during the performance of the work.

A job hazard safety analysis shall be written for the specific work and
reviewed with all personnel working on the job.

### Water Pollution Control

Prevention of water pollution shall be performed.

### Utilities

There are no known utilities near the site that will cause interference
with the work.

### Existing Structures

There are no additional existing structures along the alignment that
will need to be removed other than the ones previously mentioned.

### Use of Land 

Care shall be taken to limit impact to adjacent land. Care shall be
taken to limit noise and air pollution on the property. Pollution of the
land and water from oils, fuel and other hazardous materials shall be
avoided at all costs.

## PROJECT CLOSEOUT

All debris and unusable materials shall be removed from the site.

Prior to removal of equipment from the project, conduct walk through
with agencies involved in the project.

D.  The CO will test concrete for compliance with specifications and
    reserves the right to design and adjust concrete mix proportions.

E.  Air-entraining admixture: Use an amount that results in entrainment
    of 4 to 6 percent air, by volume, of concrete as discharged at
    placement.

F.  Slump: Not exceeding 3 inches plus or minus 1 inch when placed, nor
    5 inches when first mixed, unless a type 1 or 2 plasticizing
    chemical admixture is used to provide flowing concrete for an
    unusual placing condition, in which case provide concrete having a
    slump appropriate for placing conditions.

3.  EXECUTION

    1.  CONCRETE PLACEMENT, CURING, AND PROTECTION

        A.  Use forms to shape concrete to required lines. Design,
            engineer and construct formwork, shoring and bracing to meet
            design and code requirements.

        B.  Bring exposed unformed surface to uniform surfaces and
            produce a reasonably smooth, wood-float or steel-trowel
            finish.

        C.  Concrete temperature at placement: Between 50 degrees F and
            90 degrees F.

        D.  Cure concrete with water, curing compound, or polyethylene
            film.

            1.  Water cured: Keep concrete continuously moist for at
                least 14 days after being placed by sprinkling or
                spraying, or by other methods approved by the CO.

            2.  Curing compound application: USBR CM.

            3.  Polyethylene film: Keep concrete continuously moist for
                at least 14 days after placement.

        E.  Protect concrete against damage until final acceptance by
            the CO.

        F.  Protect concrete from damage by freezing:

            1.  Maintain concrete temperature not lower than 50 degrees
                F for at least 72 hours after placement and, if water
                cured, protect concrete against freezing temperatures
                for the duration of curing period.

            2.  After discontinuance of water curing, maintain concrete
                above freezing for the next 72 hours.

            3.  Where artificial heat is employed, vent the heater and
                keep concrete from drying.

    2.  CONCRETE REPAIR

        A.  Concrete repair: USBR M‑47.

        B.  Use the method of repair or replacement as directed by the
            CO in accordance with USBR M-47.

WAGE DETERMINATION APPEALS PROCESS

1.) Has there been an initial decision in the matter? This can

be:

\* an existing published wage determination

\* a survey underlying a wage determination

\* a Wage and Hour Division letter setting forth a position on

a wage determination matter

\* a conformance (additional classification and rate) ruling

On survey related matters, initial contact, including requests

for summaries of surveys, should be with the Wage and Hour

Regional Office for the area in which the survey was conducted

because those Regional Offices have responsibility for the

Davis-Bacon survey program. If the response from this initial

contact is not satisfactory, then the process described in 2.)

and 3.) should be followed.

With regard to any other matter not yet ripe for the formal

process described here, initial contact should be with the

Branch of Construction Wage Determinations. Write to:

Branch of Construction Wage Determinations

Wage and Hour Division

U.S. Department of Labor

200 Constitution Avenue, N.W.

Washington, DC 20210

2.) If the answer to the question in 1.) is yes, then an

interested party (those affected by the action) can request

review and reconsideration from the Wage and Hour Administrator

(See 29 CFR Part 1.8 and 29 CFR Part 7). Write to:

Wage and Hour Administrator

U.S. Department of Labor

200 Constitution Avenue, N.W.

Washington, DC 20210

The request should be accompanied by a full statement of the

interested party\'s position and by any information (wage

payment data, project description, area practice material,

etc.) that the requestor considers relevant to the issue.

3.) If the decision of the Administrator is not favorable, an

interested party may appeal directly to the Administrative

Review Board (formerly the Wage Appeals Board). Write to:

Administrative Review Board

U.S. Department of Labor

200 Constitution Avenue, N.W.

Washington, DC 20210

4.) All decisions by the Administrative Review Board are final.
