7.0 Specifications

7.1 Foundation Specifications – The following are minimum specifications. If cases where specific grain storage bin manufacturer foundation requirements exceed these minimum specifications, the more rigorous specification shall apply.

a. Contractor will adhere to the American Concrete Institute guidelines and standards for concrete placement, vibration, testing, finishing, curing, hot weather, cold weather, etc. Contractor will provide the Design Mix for minimum 3500 psi. with approval from USDA EPM.

b. Concrete shall be tested per each 20 CY of concrete by a certified concrete testing laboratory provided by the contractor. Tests shall include slump, air, temperature, and compressive strength.

2 sets of cylinders shall be made per each 20 C.Y. concrete. 1 set for 7 day strength and 1 for 28 day strength. Certified reports shall be sent to the EPM and COR.

c. 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.

d. 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.

e. 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.

f. All demolished materials, removed soil, and other debris generated shall be removed by the

Contractor.

g. Strip vegetative material and excavate as necessary to provide a stable base for the concrete slab to include grading, soil removal, soil addition, compaction, subbase installation, and any other work necessary for slab construction.

h. 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.

i. Finished dimensions, elevation, and surrounding earth shall allow for farm vehicles/machinery to access the grain storage bin loading and unloading areas on smoothed, flat or gently sloped terrain.
