Arrived on Fairway at 8:00am as crew moved back to Fairway to continue excavation. They started today on the north side of the Deer and Fairway intersection where they stopped yesterday. The Vinciguerra crew (1 operator, Jim and 9 Underground Utility Pipe Fitters, 1 Truck Driver) arrived and went east on Deer. A Cat 314C was used to dig the trench for the new 8” C 900 water pipe. The crew placed 6” of aggregate base to be used as bedding under the C900 DR 18 or DR14, with pipe placed on top of it. The DR 14 is used in conjunction with bell restraints where we center it under the sewer or where we are within 10’ of sewer mainline. They then placed base up to spring line and water jet 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. 340’ of C900 DR 18 and 20’ of C900 DR 14 was placed along Deer and backfilled along with 3 short and 4 long side services. The short services were located at 1135 Fairway, 3510, 3514 both on Deer, with the long sides being located at 3507, 3515, 3517, and 3523, all on Deer. Sand was placed around the poly pipe prior to backfill to help protect the pipe. Pipe placement ended across from 3523 Deer. A sewer lateral was hit at 3514 Deer, it was 4’ off the mark and repaired by the contractor. Saw cutting and lay out took place on Pinecrest, Vanda Lee, Osgood, Bowers, Larch and Forest. Departed site 1800 as crew continued clean up.
