SECTION 02227

EXCAVATION AND BACKFILL

A. Excavation and backfill shall include the excavation and backfilling for demolition and or removal of existing below grade structures or utilities as indicated in the specifications for all materials of whatsoever nature encountered.

A. The Contractor shall, at his expense, make such test pits and borings along the line and site of the work to satisfy himself regarding the character of the various strata of sub-surface materials and the amount of ground water that may be encountered in the course of construction and shall bid accordingly and the unit lump sum prices bid for the various pipes or structures requiring excavation shall include the difficulties to be encountered in excavation. Excavation shall include all materials excavated, encountered, including but not limited to rock, earth, shale, quicksand, gravel, sand, cinders, broken stone, concrete, paving, filled material, etc., and all miscellaneous excavation not herein specified and classified.

B. Backfill material: All on-site backfill materials shall be subject to the approval of the Engineer, and to the following requirements.

1. Shall it be as indicated on the plans.

2. Free from deleterious substances, stumps, brush, weeds, roots, sod, rubbish, garbage and matter that may decay.

3. Backfill to a height of two (2) feet above the top of the pipes, culverts and other structures with material free from stones or rock fragments larger than two inches (2") in greatest dimension, or as directed by Engineer.

4. Free of large rocks or lumps that, in the opinion of the Engineer, may create voids or prevent proper compaction.

C. Additional backfill material shall conform to Section 205 of the Pennsylvania Department of Transportation Publication 408 for Borrow Excavation.

3.01 Method of Construction

A. General Excavation - Excavation of all materials of whatsoever nature encountered shall be made to the lines and grades shown on the drawings, or as may be necessary

Section 02227 - Excavation and Backfill Page 2 of 5 to fully carry out the intent of the drawings, and of these specifications, where no grades are indicated or described. Surfaces of excavations in earth, exposed in the finished work, both level and sloped, shall be excavated in planes four inches lower than the finished surfaces, measured perpendicularly to the plans, and shall be brought up to the finished surfaces with 4" topsoil as specified elsewhere. Finished surfaces shall be true to line and grade and shall be dressed to even planes. Unless otherwise shown or stated in the drawings, all exposed slopes excavated in earth shall be one vertical to two horizontals. Slopes shall be kept true to line and grade during the progress of the work, and should any slope be scoured by storm water, or otherwise disturbed, or should any excavation be scoured or disturbed before final payment is made, the Contractor shall promptly restore the slope or excavation so scoured, gullied or otherwise disturbed to line and grade before final payment is made. No additional compensation will be paid the Contractor by reason of the encountering of any unusual or unexpected subsoil conditions.

B. Unauthorized Excavation - Special care shall be taken to prevent the movement of disturbances of earth under the foundation of the pipelines, manholes and other structures by providing adequate sheathing and bracing. Where the excavation is carried beyond or below the lines and grades given by the Engineer, or wherever the Engineer shall determine that any material has been loosened or disturbed sufficiently to reduce its supporting power, remove all such loosened material and refill all such excavated space to grade with sand or loam thoroughly rammed, in such manner as may be directed by the Engineer in order to ensure the adequate support and stability of the pipeline and other structures. All excavation and any other operation shall be confined to the width of the rights-of-way available.

C. Materials Excavated - The materials excavated shall be laid compactly on the side of the trench or excavated and kept trimmed so as to be of as little inconvenience as possible to the travelling public and to adjoining tenants. Where the streets are paved, the paving materials shall be kept separate from the other materials excavated. All streets shall be kept open for travel unless otherwise directed by the Engineer.

D. Removal of Excavated Materials - The Contractor shall not, without permission from the Engineer, remove from the line of the work any excavated materials which may be suitable for filling the trench or excavation until the same has been refilled. All excess excavation shall remain the property of the Owner and shall be disposed of at the location designated by the Owner within the limits of the Municipality at the Contractor's expense. However, if the Owner has no real need for this excess excavation, it shall be the Contractor's responsibility to dispose of said material at no expense to the Owner. Excess excavation shall be immediately removed.

Section 02227 - Excavation and Backfill Page 3 of 5

E. Removal of Water - Maintain and provide at all times during construction ample means and device which shall promptly remove and properly dispose of all water or sewage entering the excavation and structures, until all work to be built therein is completed.

F. Dispose of the water from the trenches and excavation in a suitable manner, without damage to adjacent property and in no case unless by special permission of the Engineer, shall water be allowed to run through the new pipes. Furnish all necessary machinery, power and labor to pump, bail or otherwise remove any water which may be found or shall accumulate in the trenches or other excavation and shall perform all work necessary to keep them clear of water while the work is under construction.

G. If the ground water and subsoil conditions along the line of the work are such that the

Contractor cannot successfully handle the ditch water and provide a stable, hard trench bottom by ordinary trench pumping and bailing, the Contractor shall provide and provide the necessary equipment, power and labor to employ the well point method of trench dewatering without additional compensation. All pipe, joints and concrete must be installed under absolutely dry conditions.

H. Backfilling - The backfilling of the trench will be filled by using properly compacted, common earth material. If sufficient earth cannot be obtained to completely fill the trenches, small pieces of rock may be used under the condition that the space between the walls of the trench and the outside of the pipe to a height one foot above the top of the pipe, be filled with loose, fine earth, free from stone and hand-tamped, and placed in separate layers of not more than six inches in depth and each layer covered with from six to ten inches of earth.

1. Should excavated material be clay that will not consolidate by ordinary methods of backfilling, it shall be removed from site…
