This project will require on-site testing of the concrete to include, air content, slump, and temperature. White curing http://www.sam.gov/ https://www.biopreferred.gov/ compound shall be sprayed on all exposed concrete after pour to prevent moisture loss. This project will require four (4) concrete cylinders taken for compressive strength from on-site concrete, per each 20 CY of pour, and broken two (2) by 7th day and two (2) on the 28th day. All testing shall be performed by a Certified Concrete Testing Lab and all Test Results shall be submitted to USDA. Contractor will clean up washout or remaining concrete from each pour from the worksite and from USDA Property at each pour.

Steel Canopy: Contractor will furnish design, materials, personnel, and equipment to install a new free-standing Steel Canopy extension on the east side of the existing cotton gin shed. The roof and skirt sheeting shall match existing Bldg. #21 sheeting, pictures shown below. The nominal Canopy dimensions are to be 18’W x 61’L x 23’-0” H.

The approved design must provide 15’-6” of clear width under the canopy to accommodate future machinery. The canopy shall have 3’-0” vertical skirts on (3) sides of the canopy. Roof shall be 2:12 pitch. The new roof sheeting shall flash under existing roof sheeting to match existing corrugations. Steel Canopy shall meet the recommendations of American Institute of Steel Construction, Specification for the Design, Fabrication and Erection and American Iron and Steel Institute for the Design of Cold Formed Steel Structural Members. The canopy will be free standing and to provide for a minimum of 120 mph wind loading rating. Columns will be securely mounted to new concrete column foundations. The Columns shall be painted as listed below. Conceptual Drawing shown below. Contractor is responsible for submitting Detailed Engineer Stamped Shop Drawings for the Canopy for approval by USDA EPM.

The provided Design is requested to have the new columns located as close as possible to the existing adjacent columns per the Conceptual Drawings below.

Painting Steel Columns: The contractor shall be responsible for preparing all metal for primer application and providing all paint and primer. All metal shall be pressure washed to remove loose paint, mil scale, rust, etc. Some hand removal of loose mil scale, rust, etc. may be required. All metal will be primed with (1) coat of “Sherwin- Williams” Kem Kromic Universal Metal Primer or approved equal. All metal will then be painted with (2) coats of “Sherwin-Williams” Pro Industrial DTM Acrylic Semi-Gloss or approved equal. The paint color will match existing color and color must be approved by USDA prior to paint application.

Items for Re-location: Contractor will protect and re-locate ½” diameter existing lightening protection ground cable, Cad weld. Contractor will protect and relocate approx. 65’ of 5”x5” gutters, to include (3) existing 5”x4” downspouts with existing concrete splash pads, Contractor will protect and re-locate (1) 220-volt security light, using existing circuit, to East Side of new canopy. All electrical work shall comply will National Electric Code for splicing, final location, and grounding.

Contractor Responsibility:

1. The project has a base bid to be performed per the following Specifications and Base Bid: The Contractor's approved laboratory shall collect samples of fresh concrete in accordance with ASTM C172/C172M during each concrete pour as required to perform tests specified herein. Make test specimens in accordance with

ASTM C31/C31.

2. The Contractor's approved laboratory shall perform concrete slump tests in accordance with ASTM C143/C143M. Take samples for slump determination from concrete during placement. Perform tests at the beginning of a concrete placement operation to ensure that specification requirements are met.

3. Make four test specimens for each set of tests. Test two specimens at [7] days, and the other two at [28] days. Concrete strength will be considered satisfactory when the minimum of the [28]-day test results equal or exceeds the specified [28]-day strength. Concrete which is determined to be defective shall be removed and replaced with acceptable concrete.

4. Hot Weather: Maintain required concrete temperature in accordance with Figure NRMCA NOMOGRAPH FOR ESTIMATING EVAPORATION RATE ON THE BASIS OF MENZEL FORMULA in ACI 305.1 to prevent evaporation rate from exceeding 0.2 pound of water per square foot of exposed concrete per hour. Cool ingredients before mixing or use other suitable means to control concrete temperature and prevent rapid drying of newly placed concrete. After placement, use fog spray, apply monomolecular film, or use other suitable means to reduce the evaporation rate. Start curing when surface of fresh concrete is sufficiently hard to permit curing without damage. Cool underlying material by sprinkling lightly with water before placing concrete. Follow practices found in ACI 305.1.
