Change Order Nos. 6 and 7 in
No. 549, were reviewed.
Getty that the Agenda, as proposed, be approved. Ayes: Three.
conjunction with the Waterloo Easton Avenue WPFC, Contract
Change Order No. 6 is for a net increase of $15,500.00. The change order includes: design
changes to the Final Effluent Junction Manhole, which is the connection point for Easton Plant
effluent to the river discharge line. It also revises handrail and air pipe support details on the
Aeration Basin walkway. It provides for a different sump pump for the Easton Bypass Structure.
The unit originally specified is not suitable for the explosion proof rating at this location and will
be turned over to plant staff for use elsewhere. The change order provides for upgrading the
grounding configuration at three new padmount switches and two new transformers. It also
includes removal of 30 cubic yards of soft, unstable soils found beneath the west end of the
Septage Receiving Station and replacement with compacted structural fill at the contract unit
price.
Change Order No. 7 is for a net increase of $90,393.00. The first and second items on this
Change Order are linked by a negotiated settlement whereby the city agrees to accept defective
work on two sections of concrete wall at the north end of the Aeration Basin. The two wall
segments dimensionally vary from the design cross-section to an extent that exceeds specified
tolerances, but not to an extent that constitute an unacceptable sacrifice in strength or reduces
service life, providing that waterproofing material is applied on the inside face. In exchange, the
contactor has agreed to furnish two polymer feed units at the vendor's base cost, with no
markups. The change order also provides for installation of two sections of buried 24" Satellite
RWW bypass system piping, comprising the portions of the system that must be installed now to
minimize conflicts and delays on work in progress, and avoid rework later.
Jim Hagley of Earth Tech stated that they are recommending that the city accept the bid from
Story Construction Company in the amount of $9,973,000.00 for the Anaerobic Disgesters
Project for the Water Pollution Control Facility, Contract No. 550. John T. Jones Construction
Company of Fargo, North Dakota, was the low bidder at the bid opening at the council meeting
of April 3, 2000. The company telephoned the next day that they had made a computation error,
and after reviewing the bids it is apparent that John T. Jones did make a mistake. Story
Construction's bid is approximately 5 percent over the engineer's estimate. Mr. Hagley reported
that six companies bid on the project and all the bids were close except for John T. Jones
Construction's bid.
These items are on tonight's council agenda for approval.
With no further business before the council, it was moved by Getty, seconded by Berry that the
meeting be adjourned at 5:04 p.m. Ayes: Seven. Motion carried.
