BACKGROUND
Base contract No. 06 -049 with Anchor Environmental, LLC (now known as Anchor QEA, LLC)

Waterline construction contract with Gary Merlino Construction Company, Inc. For additional
CM and inspection support, Supplemental Agreement No. 6 in the amount of $53,978.00 was
approved with Anchor QEA, LLC.
DISCUSSION
During the course of construction, the discoveries of existing system conditions that were not
known at the time of design were encountered. Included was the discovery of a previously
unknown 8" waterline, a waterline thought to be 8" was actually 12 additional efforts needed to
connect existing water services and the encounter of a previously unknown connection
requirement found at the north end of the project. Anchor QEA, LLC supplied additional support
services to complete the construction project, as well as assisted staff to analyze and negotiate
the construction change orders for a substantial savings to the City estimated at $70,000.00.
Anchor QEA LLC's fee of $21,206.00 under Supplement No. 7 for additional construction
management services has been determined to be reasonable.
