2. PROJECT DESCRIPTION

2.1 Scope: The contractor shall provide all labor and materials to install the following, as outlined in the specifications and drawings:

A. Provide joints as detailed in the drawings and supported by the UFC for full depth concrete repairs. Spacing of transverse and longitudinal joints shall match existing adjacent slabs.

B. Submit technical data, cut sheets, samples, test reports, or other items listed below using an AF Form 3000 filled out and signed in appropriate areas.

i. Concrete Mix Design.

ii. Project Schedule with percentages.

iii. Joint Detail Plan based on the Concrete Repair Plan

iv. Paint product data

v. Quality control & test reports for concrete including slump, air content, temperature and compressive strength.

vi. Fill out the 180th FW Solid Waste Disposal and Tracking Form.

C. The contractor shall mark all areas per the drawing for each step. The government reserves the right to take square footage and re-prioritize to another area within the contract area.

D. Provide lighted low profile barricades around free zone work area until the new concrete is properly cured and ready for normal aircraft traffic.

E. Remove existing concrete sections as indicated on the drawings by means of a saw and no overcut will be allowed on the corners. Existing concrete is 11-14” thick. Remove slabs so adjacent existing slabs which are to remain are not damaged. The contractor shall evaluate the affected concrete area and possibly increase the size up to 15% for final saw cut dimensions.

F. Slabs and slab joints are joined with dowels or reinforced as shown on the

Details Drawings. The contractor shall provide materials and install required joints and reinforcements to prepare for new concrete.

G. Place, consolidate and finish new concrete at the areas where concrete was removed. Concrete mix shall be a minimum of 4500 psi concrete. Concrete shall have a slump between 1” and 4” maximum with an air content of 5% +/- 1%. Water to cement ratio of mixed concrete shall not exceed 0.45.

H. Provide a finished surface at the specified grades free of defects, bumps and depressions. Concrete placed that has low or high spots (exceeds 1/4” in 12’ measured in any direction) will be replaced with no additional cost to the government. Match existing elevations at perimeter of repairs. Finish shall be a medium broom finish.

I. Saw cut contraction joints the same day that the concrete is placed. Initial saw cut shall be 1/8” wide and 3” deep (+/- 1/2”).

J. Curing: Apply 1 coat of spray applied white curing compound to new concrete as recommended by the manufacturer. Apply uniformly at a rate of 1 gallon per 200 square feet or per manufacturer recommendations.

K. Protection of concrete: Protect concrete from loss of moisture and rapid temperature change for at least 7 days.

L. Joints and Joint Sealants: ASTM 05893, DOW sill 888 or approved equal.

Provide joints as described on the drawings and in this statement of work.

Widen joints by saw cutting cured concrete so as not to damage the surface.

Joints shall be ½” wide by 1” deep. Sealant shall fill joint to within 1/16” of the top of the joint. Provide backer rod as needed. Install joint sealants according to the manufacturer’s written requirements AND dimensions for the specified joint size. Compression type preformed sealants may also be used if approved by submittal.

M. Provide concrete testing services, samples and test results for each day’s work. Test concrete for air content and for slump. Make test cylinders for testing compressive strength of the new concrete.
