Contractor shall install new #5 rebar reinforcing 16” on center (2” from bottom of pour) in each direction in all areas receiving new concrete and dowel rebar into any existing adjacent concrete of area receiving new concrete a minimum of 8” into existing paving. All new concrete in this area shall be sloped to match existing slope towards existing area drains to remain. Contractor shall remove debris and seal at joints and cracks in existing and new concrete located within this area. Coordinate all downtime with the USDA for this area of work. All existing storm intakes/utility holes/utilities shall be maintained and protected during construction as they are. Approximate area of work associated with Area 1 is 14,000 Square Feet. Contractor shall verify actual dimensions.

Contractor shall paint parking lot to match the pre-existing layout, design, and dimensioning. All lines shall be painted yellow with Alkyd or Latex paint, using commercial painting products recommended and warranted for parking lot painting. Work shall include all stall, row end cap hatching, and handicap markings within noted parking lots. Contractor shall provide and place cones and/or barriers to block off work area form vehicle parking and traffic during cleaning/preparation, painting, and curing times. Paint to be used shall comply with Master Paint Institute (MPI) 97 approved products list for Traffic Marking Paint. A certificate shall accompany batch of paint stating compliance with the applicable publication and be turned over to Owner. Paint shall be yellow for all parking lines and parking row end caps. Paint shall be blue and white for all Handicap space markings. All paint shall be mixed with reflective glass beads. Glass beads shall conform to Federal specification TT-B-1325C, Type I, gradation A. Beads shall be coated with silicone or other suitable waterproofing materials. Paint applicator shall be approved for paint and glass bead selection. The application of paint shall conform to Federal Specification TT-P-1952D. The contractor is responsible for establishing control points for marking and providing templates to control paint application by type and color at necessary intervals and is responsible to apply marking in conformance with established control points. Paint is to be applied per manufacturer’s installation requirements including but not limited to temperature and humidity restrictions. Apply paint and reflective beads uniformly with true straight lines with sharp edges and end onto properly cured, prepared, and dried surfaces in conformance with details and plans shown and established control points. Apply one coat of paint at a wet film thickness of 0.4 mm (0.015 inch). The length of lines is to be the same lengths as previous lines on lots. The width of lines is to be 4”. Disperse reflective glass beads evenly on the wet paint at a rate of 6 lbs. per gallon of paint. At the direction of the CO/COR/resident engineer, markings showing light spots may receive additional coats. The maximum drying time requirements of the paint specifications will be enforced.
