C. Topsoil (Borrow): Existing topsoil is located at the north end of the existing well pad and graded to match the existing slopes of the pad as shown on the drawings. Actual quantity of materials is unknown but estimated at less than 100 cubic yards.

3.1 PREPARATION

A. Clearing and Grubbing: The work area to be excavated, and the surface area to be covered by fill material, shall be thoroughly cleared and stripped of vegetative matter, brush, trees, stumps, roots, loose rocks, and other objectionable materials. Dispose of debris offsite in a legal manner.

B. Borrow Area: The area north of the proposed well location, outside of the proposed chain-link fence as shown on the drawings may be used as a borrow area as directed by the Contracting Officer. Borrow material(s), if approved, shall be excavated in a uniform manner so when complete the excavation will match existing adjacent grades and slopes.

C. Prewatering: Excavation areas and borrow pits may be prewatered before excavating the material.

Repair to damaged utilities shall be started immediately unless otherwise authorized by the Contracting Officer.

B. Protection of Excavation: Construct and maintain shoring, bracing, underpinning, and sheet piling necessary to protect the excavation and adjacent structures. Remove protective devices when safe to do so.

L15PC00089 / L14PS01277 Park Center Well 54/250

02322 - 2

C. Dewatering: If water is encountered, keep the excavation dewatered so that installation of forming and concrete work can be carried on under dewatered conditions. Dispose of excess water by using natural drainageways near the site to the extent of their natural capacity, when no erosion or other damage will occur.

A. Excavation:

1. General: Perform excavation to the lines, grades, and elevations as shown on the drawings and to allow for safety, placing and removal of forms and inspection. Provide proper depth with allowance made for gravel fill and concrete slabs. When frost action occurs, remove frozen soil and replace with approved soil, compacted according to the requirements for bedding.

2. Footings and Foundations: Excavation for footings and foundation walls shall be level, clean, true-to-size, and free of loose material.

a. When excavations for foundations are carried below the specified levels, refill the excavation to the required levels with bedding material specified for footings, and compact as specified.

B. Bedding

1. Concrete Slabs: Excavate and dispose of unstable or undesirable materials encountered, and those materials designated by the Contracting Officer. This material shall be replaced by bedding material placed in 6-inch maximum loose lifts. Compact to 95 percent maximum dry density as determined by AASHTO T 99, Method C.

C. Backfilling

1. Footings and Foundations: Remove forms and clean the excavation of trash and debris prior to backfilling. Place and compact fill and backfill adjacent to structures in such a manner as to prevent wedging action or eccentric loading upon or against the structures. Rocks over 2 inches maximum diameter shall not be placed within 12-inches of foundations. Backfill shall not be placed against concrete footings until the 75% of the desired final design strength of the concrete has been achieved and verified by the independent test lab. Place backfill in horizontal layers not more than 8-inches thick loose. Flooding or puddling will not be allowed. The minimum distance to be maintained by heavy equipment for spreading and compacting backfill from a wall is a horizontal distance equal to the backfill height above the footing top. Compact each layer to 95 percent of maximum dry density as determined by AASHTO T 99, Method C.

A. Testing

1. Arrange for a certified, independent testing laboratory, according to the requirements of Section 01458 - Testing Laboratory Services, to perform the required testing, recording, and distributing of the results. Soils and aggregates not meeting compaction as stated above shall be re-worked until compaction requirements are met.
