after placing pipe crew placed base around pipe and compacted it. I performed a density test on base in center of
roadway at 5’ BFG. 1st test of base compaction was low, after additional compaction the base was acceptable.
The crew continued to backfill with base and I performed another density test at 3’6” BFG and compaction was
acceptable.
I performed a final density test at 3” BFG and compaction was acceptable.

I arrived onsite and met with George and Les.
Crew began cutting asphalt into smaller pieces to begin excavation on Sherman way for new water tank lines.
Crew also placed asphalt at 1315 wild wood dr and compacted with a power roller.
Jake and Trey assemble T-Valve and placed in trench.
Shores were placed in trench and rain water was diverted away from the trench.
Crew placed 8” DR-18 into the trench and connected it to T-Valve.
I notified German of potential rain early afternoon and he gathered necessary plastic and wattles for stock piles.
after placing pipe crew placed base around pipe and compacted it. I performed a density test on base in center of
roadway at 5’ BFG. 1st test of base compaction was low, after additional compaction the base was acceptable.
The crew continued to backfill with base and I performed another density test at 3’6” BFG and compaction was
acceptable.
I performed a final density test at 3” BFG and compaction was acceptable.
