Riverton approves $427,644 street‑sweeper purchase after bidding dispute

RIVERTON, Wyo. — Riverton City Council voted Aug. 5 to award a contract to Floyd's Truck Center for a new dual‑engine regenerative air street sweeper, a purchase city staff said is needed to restore regular street sweeping after the fleet vehicle went out of service.

Council members approved the purchase after staff said two other bids had been received and evaluated; the lowest bid was rejected as nonresponsive because it omitted or crossed out required specifications. The city budgeted $397,000 for the unit; staff recommended accepting Floyd's bid of $427,644 and using unobligated sanitation fund cash to cover the difference.

City staff said the regenerative air machine was specified to protect the sweeper from premature failure on Riverton’s chip‑seal and gravel‑affected streets. Public works staff highlighted features they considered essential — including a multi‑pass centrifugal dust separator and a maximum inlet opening size of one quarter inch — that the nonresponsive low bid did not meet.

Council debated short‑term alternatives before finalizing the award. Vendor Intermountain Sweeper Company, which also attended the meeting, told council members the city could rent a comparable machine at about $12,000–$14,000 per month (plus mobilization) if the city wanted a temporary option while the new sweeper is built. Staff said renting for intermittent months could cost roughly $80,000 a year for six months of service; the council discussed renting for a short period this year while a purchased unit is delivered (estimated lead time: 8–9 months).

Council members also discussed useful life and long‑term cost: staff and vendors said modern sweepers typically have a useful service life of seven to 10 years. Council members weighing budget pressures noted that renting repeatedly could exceed the purchase cost over multiple years, while others urged fiscal caution about drawing from reserves.

The motion to award the contract to Floyd’s Truck Center was made on the council floor and seconded; the council approved the award. The formal purchase will proceed through procurement and the sanitation fund. Staff said the city will consider rental options to cover this season if needed.

The purchase came under the city procurement rules requiring evaluation of responsiveness to specifications; staff explicitly recommended the lowest responsive bidder rather than the numerically lowest bid because the low bid failed to meet bid specifications.

The city did not publish a full roll‑call vote in the transcript; the council recorded the motion as passing on voice votes during the meeting.

Clarifying details: the city budgeted $397,000 for the sweeper, Floyd’s Truck Center bid $427,644, and a competing bid from Target Equipment was $368,265 but was judged nonresponsive. Intermountain Sweeper Company quoted monthly rental rates in the $12,000–$14,000 range for temporary service, excluding mobilization and operator costs.

What’s next: staff will complete procurement paperwork and coordinate payment from the sanitation fund; the council discussed the possibility of short‑term rental while the new unit is in production.
