E. Trees shall be felled into the area being cleared when ground conditions, tree lean, and shape of clearing permit. Controlled felling shall be used that will ensure the direction of fall when necessary to prevent damage to property, structures, trees DESIGNATED to remain, or traffic.

F. Fire-dangerous dead trees or unstable live trees, DESIGNATED by the Engineer within 200 feet slope distance of the centerline of roads shall be cut off not more than 12 inches above the uphill ground line and treated in accordance with construction slash.

G. Branches on remaining trees or shrubs shall be trimmed to give a clear height of 14 feet above the roadbed. Tree limbs shall be trimmed as near flush with the trunk as practicable.

SLASH TREATMENT

A. Treatment of construction slash larger than 3 inches in diameter and 3 feet in length shall be accomplished by Method A – Scatter on site as designated by the Engineer. Pieces of wood less than 3 inches in diameter and 3 feet in length will be scattered in designated areas. No construction slash shall be deposited in lakes, meadows, streams, or streambeds. Construction slash that interferes with drainage structures shall be removed immediately. Trees adjacent to the clearing limits damaged beyond recovery shall be felled and disposed of in accordance with treated as construction slash.

END OF SECTION 02102

02224 – EXCAVATION, EMBANKMENT AND BACKFILL

02224 - 38

PART 1 - GENERAL

02224 -

This section specifies excavation, embankment and backfill, furnishing, hauling and placing of backfill and embankment material; watering; compaction; disposal of excess or unsuitable excavated material. Final grading for decommissioned cisterns. Borrow material and haul will be considered incidental in the contract and a direct separate item payment will not be made.

1.2 - Material Classification

02224 -

02224 - Material to be excavated is unclassified. Contractor is advised to classify the material to their satisfaction.

PART 2 - PRODUCTS

2.1 - Backfill Material

Backfill material shall be readily compactable excavated material free of frozen or organic material, highly plastic clay or other objectionable material and shall contain no rocks larger than 6 inches in diameter.

2.2 - Water

Water shall be reasonably clean and free of injurious substances.

2.3 – Borrow Material

Borrow material shall conform to Sections 02224 – Excavation, Embankment and Backfill.

PART 3 - EXECUTION

3.1 - Excavation

02224 - 40

All suitable excavated materials shall be used in construction of embankments, slopes, and backfill.

No excavated material shall be placed in lakes or live streams.

Rocks too large to be incorporated into embankments shall be broken for incorporation into the embankment or relocated to locations approved by the COR for use as barrier rocks.

3.2 - Backfill

General backfill shall be placed in horizontal layers not exceeding 12 inches (loose measure) and compacted. Each embankment layer shall be leveled and smoothed before compaction and placement of subsequent layers. Compaction shall be as shown in Section 3.6.

Finished surfaces shall be reasonably smooth, compacted, and shall drain without ponding.

02224 - 35

Backfilling Adjacent to Concrete Remove all forms and clean the excavated area of all debris. Remove any standing water from excavation. Obtain approval from Engineer prior to placement of backfill. Do not backfill until concrete has been in place for a minimum of 7 days and has attained sufficient strength to withstand imposed loads.

3.3 - Embankment

Embankment shall be placed in horizontal layers not exceeding 12 inches (loose measure) and compacted.

Bring all embankments to suitable elevations above grade to provide for anticipated settlement, shrinkage, and required compaction.

Embankment material shall not be dropped on any structure.

02224 - 28

3.4 - Grading

02224 - 28

02224 - 59 All areas covered by the project including excavation and embankment areas and adjacent transition areas, shall be uniformly graded so that finished surfaces are at elevations indicated and approved by the COR. Slope grade away from structures a minimum of ¼-inch per foot unless otherwise indicated to provide drainage away from structures.

All areas covered by the project including excavation and embankment areas shall be final graded so that all ruts and berms are removed.

02224 - 41

3.5 - Excess Excavated Material

All suitable excavated materials shall be used as backfill.

02220-70

All excavated materials not required or unsuitable for backfill shall be utilized on the site or removed to waste areas as directed by the COR.

3.6 - Compaction

Place suitable material in layers no more than 12 inches thick.

Placing individual rocks or boulders greater than 24 inches in diameter will be permitted, provided that the embankment will accommodate them and that they are at least 6 inches below sub grade. Carefully distribute rocks and fill the voids with finer material to form a dense and compacted mass.

02224 - 71

02224 - 3 Where material containing large amounts of rocks is used to construct embankments, make layers of sufficient thickness to accommodate the material involved. Construct a solid embankment with adequate compaction by working smaller rock and fines in with the larger rocks to fill the voids, and by operating hauling and spreading equipment uniformly over the full width of each layer as the embankment is constructed.
