L <br /> L <br /> 1 . Drainage <br /> So that construction operations progress successfully, completely drain construction <br /> site during periods of construction to keep soil materials sufficiently dry. The <br /> Contractor shall establish/construct storm drainage features (ponds/basins) at the <br /> earliest stages of site development, and throughout construction grade the construction <br /> area to provide positive surface water runoff away from the construction activity and/or <br /> provide temporary ditches, swales, and other drainage features and equipment as <br /> required to maintain dry soils. When unsuitable working platforms for equipment <br /> operation and unsuitable soil support for subsequent construction features develop, <br /> remove unsuitable material and provide new soil material as specified herein. It is the <br /> responsibility of the Contractor to assess the soil and ground water conditions <br /> presented by the plans and specifications and to employ necessary measures to permit <br /> construction to proceed. <br /> 2 . Dewatering <br /> All water encountered during excavation shall be promptly and completely removed to <br /> a depth below the exposed excavation surface sufficient to provide a dry working <br /> surface. The excavation shall be kept dry until the work to be built or placed therein <br /> has been completed as specified. Dewatering shall be done in a manner that will not <br /> cause sloughing or caving of the excavation walls. Water from said dewatering shall <br /> be disposed of in a manner as will not result in violations of State water quality <br /> standards in receiving waters, nor cause injury to public health nor to public or private <br /> property, nor to the work completed or in progress. Any and all damage caused by <br /> dewatering shall be promptly repaired by the Contractor at no cost to the Owner. The <br /> receiving point for water from said operation shall be approved by the applicable <br /> regulatory agency and the Engineer. The Contractor is responsible for obtaining all <br /> required permits and any other approval necessary. <br /> C. Underground Utilities <br /> Location of the existing utilities indicated on the Drawings are approximate only. The <br /> Contractor shall physically verify the location and elevation of the existing utilities <br /> indicated prior to starting construction. The Contractor shall contact Sunshine One Call at <br /> 1 -800-432-4770, 48 hours prior to commencement of excavation for assistance in locating <br /> existing utilities. <br /> D. Machinery and Equipment <br /> Movement of construction machinery and equipment over pipes during construction shall <br /> be at the Contractor's risk. Repair, or remove and provide new pipe for existing or newly <br /> installed pipe that has been displaced or damaged. <br /> 3 . 03 EXCAVATION <br /> Excavate to contours, elevation, and dimensions indicated. Reuse excavated materials that meet the <br /> specified requirements for the material type required at the intended location. Keep excavations free <br /> from water. Excavate soil disturbed or weakened by Contractor's operations, soils softened or made <br /> unsuitable for subsequent construction due to exposure to weather. Refill with common fill and <br /> compact to 95 percent of ASTM D 1557 maximum density. Unless specified otherwise, refill <br /> excavations cut below indicated depth with common fill and compact to 95 percent of ASTM D <br /> 1557 maximum density. <br /> it 02302 — Excavation and Fill <br /> 02302 - 5 <br />
