Subject: EMERGENCY APPROVAL Change order 2 for Water Booster Station project
Attachments: P-1D Relocate Valve.pdf
Importance: High
Hi John,
As we discussed the Wastewater Department is requesting emergency approval of a Change Order for the Water Booster Statin project. Below is detail
information from Bill Keating, Wastewater Engineer on the change order needed and why emergency approval is required. Though this Change Order is
under $25,000, a previous Change Order #1 in the amount of $5,961.83 has already been processed bringing total Change Orders over $25,000.
Below is a summary of the correspondences with the Contractor regarding the proposed change order along with backup costs for the Water Booster Station
project:
9/12 -The Contractor’s subcontractor doing he earthwork, NE Earth Mechanics, was digging on west side of water booster station to determine location to
install new water valve that will connect to new water pipe and water booster station. After digging and exposing existing water pipe, contractor determined
they could not install taping machine with fitting at that location.
9/19 — contractor resumed work to locate a connection point to existing water pipe. They located an electrical duct bank and 2 other water lines crossing the one
they need to tap into. The water lines and duct bank were not shown on the design drawing due to lack of record drawings showing these utilities. There was no
way of knowing what buried utilizes existed without accurate record drawings. The contractor determine a tap location where there is 9-feet of pipe {clearance
needed) with no interference approximately 25 feet west of original tap location. New tap location Is in service road.
9/20 — contractor provided a proposed change order for anticipated extra work. Estimate was for $33,410.91. Subsequent correspondences between Wastewater
and Contractor lowered costs to $24,764.69 by having City do the pavement repair of service roadway.
Contractor stated in email that he wanted approval on cost proposal on 9/20 otherwise the subcontractor doing the earthwork will leave site for a few weeks.
Contractor also stated he has another job starting in mid October and needed to keep this job moving forward. Woodard Curran (consultant) recommended
issuing a work directive informing the Contractor to keep work moving forward while the Change Order is reviewed and costs substantiated. A work order for
contractor to continue working was issued on 9/20 pending authorization of City to allow for emergency change order approval.
