Attached is Change Order No. 4 for the Titus Lift Station and Force Main project submitted by WRH, Inc.
This change order is to compensate WRH, Inc for dewatering work and equipment over and above what was anticipated at
the time of the bid. The months of May and June received considerably more than normal precipitation. That excess
precipitation required more dewatering pumps and more labor hours to drawdown the groundwater at the lift station site to
install the wet well than was anticipated in December 2023 at the time of the bid.
AECOM and City Staff recommends the City approves Change Order No. 4 for the addition of $16,250.00 and a revised total
contract cost of $6,279,720.88. The increase is 1.55% of the original contract including all change orders.
