All on site at 7am. Lovin removed forms from section S8 and finished forming N9 and poured concrete at 2:00pm. Then started tying rebar for section N7. DNHI hauling bad material from N side of creek to staging area, appr. 90’ of N side accessible now. Also drilled drain holes in sheet pile, 77 today. At end of day as I was checking everything to leave, I found that 1 of the 8” bypass pumps was not running properly. I contacted Tom Howe with United and gave him the diagnostic codes that were displayed. He contacted his service man and he stated that it was a malfunctioning DEF system and the pump will need swapped out. They are supposed to be on site in the AM first thing with another unit.
