Summary
Council awarded a low‑bid construction contract to TF Contracting Services LLC not to exceed $6,776,999 for a 16‑ and 36‑inch Zone 4 pipeline (about 4,200 linear feet), funded from the water enterprise fund (ratepayer‑funded). Engineers had estimated $8.6 million.
Scottsdale City Council on Dec. 1 approved a construction contract to build the city’s Zone 4 16‑ and 36‑inch water pipeline, awarding the work to TF Contracting Services LLC for a contract amount not to exceed $6,776,999.
City engineer and project staff described the work as roughly 4,200 linear feet connecting existing mains north of Loop 101 on the east side of Hayden to the city’s water campus, moving water from west to east to serve higher‑density development in the State Land parcels in that area. Staff said the project went to a low‑bid solicitation; the city’s engineers had estimated the work at about $8.6 million and received other bids ranging up to $9 million.
Councilmember Barry Graham questioned the choice of a low‑bid delivery method versus construction management at risk (CMAR); staff explained CMAR suits more complex, multi‑phase projects while a straightforward pipeline is commonly awarded on a low‑bid basis. The project is funded through the water enterprise fund (ratepayer water distribution improvements account), and staff said no debt issuance is planned for this contract.
Council moved and passed resolution number 3,13551 to authorize contract number 26 IFB 018 and proceed with the construction contract.
