DSS-6 EXISTING CONDITIONS The Contractor is advised that the Engineer will furnish to the Contractor, where available, plans of the existing collapsed or otherwise defective Storm, Sanitary or Combined Sewers. The Contractor is further advised that since the reconstructed sewer is to be within the same trench where the existing collapsed or otherwise defective pipe sewer was constructed, it is assumed that the original trench was backfilled with acceptable materials and that no exceptionally large boulders, or other obstructions would hinder or delay the excavation work. If boulders, rip-rap and other large objects as herein before specified in excess of one-half (1/2) cubic yard in volume are encountered during the excavation down to the top of the existing collapsed or otherwise defective pipe sewer, payment for the removal of same will be paid for at the unit price bid for Item No. 70.51EO - EXCAVATION OF BOULDERS IN OPEN CUT. The entire boulder must be measured where practicable. The resultant void must be backfilled and paid for under Item No. 73.41AG - ADDITIONAL SELECT GRANULAR BACKFILL. The average depth to be excavated to subgrade for the reconstructed sewer is eight (8) to nine (9) feet, varying from a minimum depth of four (4) feet to a maximum depth of thirty (30) feet. Deeper sewer excavations to a maximum depth of thirty (30) feet, must be paid for under Item No.73.31AE2 - ADDITIONAL EARTH EXCAVATION INCLUDING TEST PITS (OVER 12’ TO 16’ DEPTH), Item No. 73.31AE3 - ADDITIONAL EARTH EXCAVATION INCLUDING TEST PITS (OVER 16’ TO 20’ DEPTH), Item No. 73.31AE4 – ADDITIONAL EARTH EXCAVATION INCLUDING TEST PITS (OVER 20’ TO 24’ DEPTH), Item No. 73.31AE5 – ADDITIONAL EARTH EXCAVATION INCLUDING TEST PITS (OVER 24’ DEPTH)
