3.1.4.1 Drainage

So that construction operations progress successfully, completely drain

SECTION 31 23 00.00 20 Page 10 construction site during periods of construction to keep soil materials sufficiently dry. Throughout construction grade the construction area to provide positive surface water runoff away from the construction activity and/or provide temporary ditches, swales, and other drainage features and equipment as required to maintain dry soils, prevent erosion and undermining of foundations and pavement. When unsuitable working platforms for equipment operation and unsuitable soil support for subsequent construction features develop, remove unsuitable material and provide new soil material as specified herein. It is the responsibility of the Contractor to assess the soil and ground water conditions presented by the plans, specifications and government furnished information (GFI) and to employ necessary measures to permit construction to proceed.

Excavated slopes and backfill surfaces shall be protected to prevent erosion and sloughing. Excavation shall be performed so that the site, the area immediately surrounding the site, and the area affecting operations at the site shall be continually and effectively drained.

3.1.4.2 Dewatering

Groundwater flowing toward or into excavations shall be controlled to prevent sloughing of excavation slopes and walls, boils, uplift and heave in the excavation and to eliminate interference with orderly progress of construction. French drains, sumps, ditches or trenches will not be permitted within 3 feet of the foundation of any structure, except with specific written approval, and after specific contractual provisions for restoration of the foundation area have been made. Control measures shall be taken by the time the excavation reaches the water level in order to maintain the integrity of the in situ material. While the excavation is open, the water level shall be maintained continuously, at least 2 feet below the working level. It is the responsibility of the Contractor to assess the soil, ground water, and river conditions presented by the plans, specifications, GFI, publically available information and to employ necessary measures to permit construction to proceed. Any pumped water must be free of soil particles. Pump intakes are required to be filtered.
