Arrived on Forest at 8:00am and was informed that they were continuing on Vanda Lee. Excavation began at 3593 and ended at the intersection with Betty Rae. The crew also began work on Shirley at the intersection with Herbert and ended at The Vinciguerra crew (1 operator, Jim and 9 Underground Utility Pipe Fitters, 1 Truck Driver) arrived and began the excavation on the north side of Vanda Lee. 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. 86’ of DR14 was placed on Vanda Lee and was backfilled along with 2 services, 1 long and 1 short. They were located at 3593, long and 3601, short. 48’ of DR 14 was also placed on Shirley along with 53’ of DR 18. There was also a marking error on Shirley for the service at 3572. The main is on the north side of the street and the service was marked as though it came off the main. The contractor searched for it but had no luck. Larry with STPUD was called and when he arrived he marked the service line on the south side of the road. The contractor was not happy as they had spent hours looking for it. 2 services were also run on Shirley, both short. They were located at 3572 Shirley and 1063 Herbert. The resident at 3601 Vanda Lee (where the service was leaking) did arrive on the weekend and STPUD came out to turn on the water. The service was run from the new main to his meter and backfilled.
