Platteville awards Pine Street water-main repair contract after April break; project to include detours and temporary water service
Summary
The council awarded Contract 16-25 to Temporally Excavating for Pine Street water-main replacement (Oak to Chestnut) after emergency quotes; contractor low-bid amounts plus contingency yield an estimated total project cost of $854,129.45 with traffic detours and temporary aboveground water service for affected homes and businesses.
The Platteville Common Council voted June 10 to award Contract 16-25 for Pine Street water-main repairs to Temporally Excavating after staff described emergency quotes taken following an April 8 water-main break.
Public-works staff said four contractors were invited to quote and that Temporally Excavating submitted the low bids for both the base and alternate segments. Staff reported the contractor line items as approximately $255,026 for the Oak-to-4th segment and $426,103.45 for the 4th-to-Chestnut alternate; adding traffic control (about $15,000), engineering (about $33,500–$42,000) and contingencies yields an estimated total project cost of $854,129.45.
Staff recommended setting a $25,000 allowance to address potential undermined pavement or curb and advised that the Pine Street repairs would replace the water main in the existing alignment close to the existing pipe. Because about 10 service connections are tied to the existing main near 4th Street, staff said a temporary aboveground water system will be installed to keep homes and businesses supplied while crews work in the same trench location.
Councilors discussed whether to limit the work to Oak–4th or proceed through Chestnut, noting prior repeated breaks in the upper section and the risk of additional repair work if the second segment were deferred. Staff explained the water-and-sewer commission controls the utility budget and that the council must authorize borrowing; completing the Chestnut segment would require adding the amount to the utilities' borrow and processing a budget amendment.
Council moved and approved the recommendation to award the contract to Temporally Excavating. Staff said the contractors provided varied completion schedules: some bidders offered expedited timing at higher cost while Temporally and other low bidders had schedules into July and August with contingency for weather; staff presented detour plans that would temporarily convert Furnace Street to one-way to route westbound traffic.
