(A) Excavation and backfill shall include all excavation, backfilling and compacting; disposal of surplus material; furnishing additional backfill material; restoration of all disturbed surface; and all other work incidental to the construction of trenches, including any additional excavation which may be required for manholes or other structures forming a part of the pipe line.
(B) The contractor shall excavate all materials encountered to the depth indicated or specified. All excavated material suitable for backfill shall be deposited in an orderly manner, a sufficient distance (two foot minimum) back from the edge of the excavation to avoid roll-backs, slides or cave-ins. Material not suitable for backfill shall be removed to a disposal area provided by the contractor.
(C) All work shall be scheduled to keep streets, sidewalks and utilities in usable condition and to avoid owner inconvenience insofar as practicable during construction. All obstructions (i.e., underground and above ground utilities, bollards, signs, mailboxes and the like) removed to accommodate construction equipment or to facilitate excavations shall be restored at no additional cost to the owner. Care shall be exercised in operating equipment beneath or adjacent to trees, plantings and shrubbery to prevent damage.
(D) Unless specifically set forth as a bid item, excavation, bedding and backfilling for trenches and appurtenances shall be incidental to the construction.
(E) Reference to maximum density shall mean a soil density not less than the stated percent of optimum density for soil as determined by the latest revision of ASTM Specifications D-698, “Standard Proctor Density”.
