The earthwork requirements must not conflict with the recommendations in the Contractor-provided Geotechnical Report.

Remove and save topsoil (approximately first 20 centimeters of excavation). When restoring the site to finish grade, place topsoil back in excavated areas that do not include proposed paving or structures. Excavated material (below topsoil), if satisfactory for reuse per the Geotechnical Report, may be used on the project site where fill is required. Unsatisfactory material may be disposed of on-site in a location approved by the COR. Borrow material may be required for construction from sources off site. Borrow materials are to be free of hazardous materials and contaminants. Any soil brought in from off-site sources must be certified clean.

In the absence of Host Nation requirements and geotechnical recommendations, fill and backfill must be placed in layers of 20 centimeters loose thickness and compacted to a minimum 95% of the maximum dry density as determined by Host Nation test method equivalent to ASTM D-1557 (Modified Proctor test). Provide density tests on all lifts at a frequency of 1 test per 40 square meters for foundations and parking, and 1 test per 30 meters of road and utility trench.

b. Finished grades of paved surfaces adjacent to buildings and structures must slope away from all exterior edges with a minimum slope of 2% for the first 2 meters.

c. Finished grades must not create stagnating water or ponding anywhere on the project site, nor create ponding on adjacent properties. Provide storm improvements if ponding is unavoidable.

d. Set finished floor elevations a minimum of 15 centimeters above finished grade at the perimeter of the building, with the exception of finished grade at entry points.

e. Set building finish floor elevations at a minimum of 30 centimeters above the local 100 year flood level.

This includes coordination of any work to be performed by the utility owner. Choice of materials and products for utility installation must be coordinated with the utility owner (customer or third party) to ensure proper integration and compliance with existing systems and allow for easy maintenance and repair of the utilities in the future.

Provide corrosion protection for utilities that provides the minimum life expectancy specified in GENERAL Section 1.0. Any piping or equipment exposed to sunlight must be coated with protective coatings suitable for UV exposure with a minimum expected coating life of 10 years before recoating.

2.10.1 STORM SYSTEM

The proposed storm system may discharge offsite to an approved location, or to an on-site infiltration system if the Geotechnical Report supports infiltration. Locate infiltration facility a minimum of 3 meters

3-Jun-19 Page 14 of 47 from buildings and the dripline of trees. A pump system is not allowed. In the absence of host nation standards, design the storm drainage system per UFC 3-201- 01, Chapter 3-Storm Drainage Systems.
