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 />02302 = 5 <br />02302 — Excavation and Fill <br />
