Do not cover or enclose work of this Section before obtaining required inspections, tests, approvals, and location recording EXISTING UTILITIES Before starting grading and excavation, establish the location and extent of underground utilities in the work area. Exercise care to protect existing utilities during earthwork operations. Perform excavation work near utilities by hand and provide necessary shoring, sheeting, and supports as the work progresses. Maintain, protect, relocate, or extend, as required, existing utility lines to remain which pass through the work area. Earthwork

21 Protect active utility services uncovered by excavation. Notify respective utility companies and City representative of damage caused to active utilities immediately. Remove abandoned utility service lines from areas of excavation. Cap, plug, or seal abandoned lines at source of connection and identify termination points at grade level with markers, after notification is provided to the City representative. Accurately locate and record abandoned and active utility lines rerouted or extended on project record documents SITE GRADING B GENERAL Perform grading within contract limits, including adjacent transition areas, to new elevations, levels, profiles, and contours indicated. Provide uniform levels and slopes between new elevations and existing grades. Obtain approval of scarified subgrade surfaces by City's representative prior to filling operations. Scarify, dry, and compact soft and wet areas; remove and replace unsuitable subgrade materials with an approved fill material. Take corrective measures before placing fill materials. Thoroughly scarify existing soil surface to a depth of 10" and as shown on the Soils Report and verify scarification with City's representative prior to placing fill material in mounded areas. Spread approved fill material uniformly in layers not greater than 12" of loose thickness over entire fill zones of planting areas. 1. Lift thickness requirements may be modified by City s representative to suit equipment and materials or other conditions when required to assure satisfactory compaction. 2. Place and compact each layer of fill before placing additional fill material. Repeat filling until proposed grade, profile or contour is attained. 3. Suspend fill operations when satisfactory results cannot be obtained because of environmental or other unsatisfactory site conditions. Do not use over-saturated fill materials. Do not place fill material on over-saturated subgrade surface. 4. Grade surfaces to assure positive drainage and to prevent ponding and pockets of surface drainage. 5. Protect finish graded areas from traffic and erosion. Keep free of trash and debris. Repair and reestablish grades in settled, eroded and damaged areas. If, in the opinion of the City, the completed site grading does not reflect the intent of the Contract Documents, an independent surveyor may be hired to verify the grades. If the grades are correct, the City will pay for the survey. If the grades are incorrect, the cost of the survey will be deducted from the Contract price. Earthwork
