Arrived on Fairway at 8:00am as crew moved back to Fairway to continue excavation. They started today on the south side of the Blackwood and Fairway intersection at the hydrant valve that had been previously placed. The Vinciguerra crew (1 operator, Jim and 9 Underground Utility Pipe Fitters, 1 Truck Driver) arrived and went south on Fairway where a Cat 314C was used to dig the trench for the new 8” C 900 water pipe. The first piece of pipe used today was the DR 14 as it was centered under the existing sewer. With the sewer lines nearer finish grade it appeared that the contractor would have to switch between the 14 and the 18 depending on the situation. There was a 5’ gap between the first 2 pipes today so the contractor can split the pressure testing and flushing in half instead of trying to do it all in one shot. This had been agreed upon by Austin with Vinciguerra and Adrian with STPUD. The crew placed 6” of aggregate base to be used as bedding under the C900 DR 18 or DR14, pipe placed on top of it. The DR 14 is used in conjunction with bell restraints where we go under the sewer or where we are within 10’ of sewer mainline. They then placed base up to spring line and water jetted it to make sure there were no voids under the pipe. 1’ of aggregate base was then placed over the pipe and compacted by jumping jack whackers. 95% of the maximum dry density is required on base and testing was performed. The maximum dry density of the base is a 132.6 at 7.2% moisture as provided by CME on 5-18-22. The results of the testing can be found in this report. The native material that was placed was also tested using a 119.6 maximum dry density and 11.5% moisture. These numbers were also provided by the CME laboratory. Results for this testing can also be found in this report. Although the the specifications call for 95% had been informed by Adrian with STPUD that 90% would be satisfactory on the intermediate backfill. A compaction wheel attached to an excavator was used for compaction efforts. 160’ of C900 DR 18 and 60’ of C900 DR 14 was placed along Fairway and backfilled along with 3 short and 3 long side services. The short services were located at 1111, 1117,and 1121 with the long side being located at 1108, 1112 and 1114 all on Fairway. Sand was placed around the poly pipe prior to backfill to help protect the pipe. Pipe placement ended at the Fairway and Deer intersection. Departed site 1730 as crew continued clean up.
