Arrived onsite at 8:00am and was informed that they were continuing on Shirley with todays excavation 3620 Shirley and ending on Bowers across from 3600 Forest. The Vinciguerra crew (1 operator, Jim and 9 Underground Utility Pipe Fitters, 1 Truck Driver) arrived and continued the excavation on the south side of Shirley, the contractor also began excavation on Bowers leading to Bill. 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 with pipe placed on top of it. 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. 40’ of DR14 was placed on Shirley and was backfilled along with 85’ of DR 18 (Bowers footage added) and 1 service. The service was located at 3620 Shirley. Hydrants and services were also worked on at the Bijou project with 4 services being placed, they were located at 3532, 3506 Cloverdale, 1076 Glenwood and 1079 Fairway. The STPUD locators were called out again as confirmation was requested on the area of Bowers between Shirley and Bill. Bill came out and remarked the services and explained that it was a service with a T leading to another service on the west side of Bowers. STPUD was again called when a cluster of unknown water pipes were found in the trench as the contractor crossed Shirley. Bill once again arrived along with Cuz and Adrian from STPUD along with Wayne Vinciguerra. It was determined that the majority of the pipes were abandoned but had been left and it was confirmed that no mainline runs on the west side of Bowers. Then walked south down Bowers with Wayne Cuz and Adrian to review marks and set up more locates.
