Earthwork 02310-5

PART 3 - EXECUTION 3.01 PREPARATION

Establish extent of grading and excavation by area and elevation. Designate and identify datum elevation and project engineering reference points. Set required lines, levels and elevations.

Do not cover or enclose work of this Section before obtaining required inspections, tests, approvals, and location recording.

3.02 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. Protect active utility services uncovered by excavation. Notify respective utility companies 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.

Accurately locate and record abandoned and active utility lines rerouted or extended on project record documents.

3.03 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.

Earthwork 02310-6

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. Install drainage swales as indicated on the Drawings. 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 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.

3.04 BACKFILLING / FILLING FOR PAVING & WALLS

Before filling, remove debris, large rocks, formwork and loose material.

Proof-roll areas to receive fill with rubber tired roller of sufficient weight. Weak areas or areas where excessive pumping is noted shall be removed, and if required by the City, replaced with select fill. Prior to placing fill, scarify surface to a depth of 6 inches. Moisture content of loosened material shall be such that first layer of fill will readily bond to surface.

Top 6 inches shall be free from rocks larger than 3 inches diameter.

Place in maximum 8-inch lifts and compact per ASTM D 1557 at optimum moisture content (-1% to +3%). This lift and compaction requirement does not apply to planting areas. Moisten fill to allow drying to correct moisture content before compaction. Do not place fill on subgrade that is over-saturated. Paving subgrade per plan and soils report.

Allowing for total thickness of finish paving and base material, fill under paving to bring subgrade to proper elevation.

Soft areas that develop under construction operations shall be scarified, aerated or moistened. Compact to full depth required to obtain specified density for each layer.

3.05 EXCAVATING

It is the Contractor's responsibility to investigate the likelihood of caliches or hard rock excavation. The City will not provide any additional compensation to the Contractor for hard rock or caliches excavation.

Earthwork 02310-7

3.06 FINISH GRADING

Grade uniformly with rounded surfaces at tops and bottoms of abrupt changes in plane. Hand grade steep slopes, areas that are inaccessible for machine work and areas around existing plants.

Slope graded surfaces to drain water away from structures, walls, etc.; minimum slope is 1/4 inch per foot. Grade areas to elevation and slopes indicated without depressions causing pocketing of surface water or humps, producing localized runoff and erosion. Ponding of water on site is not allowed. Finish surfaces to be not more than 0.10 foot above or below established grade elevation.

See Subsection 3.03 Soil Preparation under Section 02480 Planting for additional fine grading requirements.
