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 continued up Fairway to the Blackwood “T”. The pipe had to be lowered in the intersection to achieve proper clearance with the existing sewer. Two, 45 degree fittings were used to lower the pipe and two more were used to bring back to normal depth. An 8’’ T w/3 8’’ gate valves was placed at station 17+80 Lt Fairway with hydrant valve placed at 17+95 Lt Fairway. Kickers of concrete was placed at the 45s and behind the valves at the vertical offset. 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 as well as 1 from Thursday that was back calculated. 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. The mole was used once again to install long side services at 1098, 1078 Fairway. Lay out was also performed at the south end of Fairway along with Vanda Lee and Osgood on the Bowers project. Austerman was on-site to perform saw cutting in these areas along with service areas in various locations. Departed site 1730 as crew continued clean up.
