Arrived on Fairway at 8:00am and as crew prepared to head south on Fairway. The Vinciguerra crew (1 operator, Jim and 9 Underground Utility Pipe Fitters, 1 Truck Driver) arrived and began to head east on Blackwood. 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, 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. 250’ of C900 DR 18 ending at 3518 Blackwood was placed and backfilled along with 3 short side services. The services were located at 3510, 3514 and 3518 all on Blackwood. Sand was placed around the poly pipe prior to backfill, there was a question about that yesterday but there was no question today. A thrust block was also poured at the “T” in the intersection of Fairway and Ferndale. Departed site 1730 as crew continued clean up.
