Sealed bids were received for the US 52 Traffic Flow Enhancement Project. City
Engineer Gus Psihoyos recommends award of the contract to the low bidder, Portzen
Construction, Inc., in the amount of $970,792.42, which is 14.3% over the estimate of
probable cost. Much of this project is located in the downtown area where there are
many underground obstacles and unknowns which could lead to additional costs versus
similar work at other locations. City Engineer Gus Psihoyos has identified additional
funding sources.
I concur with the recommendation and respectfully request Mayor and City Council
approval.
