Visual observation techniques were employed to assure compliance with project drawings/specifications, applicable codes, and materials submittals. The following observations were made on site today

Upon arrival at the jobsite, work was already in progress with the contractor placing and compacting a two (2)-foot lift. A Bulldozer Komatsu 61px was used for spread & a Sakai Sheepsfoot was utilized for compaction.

A proof-roll on the deceleration lane was performed on 04-28-22 . Ram Mogulla P.E. of ASEC was present for this proof-roll to evaluate the existing subgrade soils.  Several zones of failure were observed on the west side of the decel lane closest to McEver Rd.  Ram Mogulla recommended removal and replacement of two (2) feet of material on the north side starting at northwest of the decel lane heading south to the existing manhole, along side Gainesville St. The material will be replaced with suitable structural fill and recompacted. In addition the entire decel lane will require removal and replacement with structural fill in the top 6 in .
