The National Park Service (Denver Service Center) wants a contractor to repair Conzelman Road. The work is a new retaining wall on drilled concrete piles, a new grade beam carrying a steel bridge rail, new guardrails, and road replacement to match the existing road. The notice gives only "Conzelman Road" (a GOGA project) as the location. The estimated price is $1M to $5M, and the solicitation text says it is a HUBZone acquisition and currently unfunded.
Watch out for
- Set-aside conflict: SAM.gov says none, solicitation says HUBZone. The SAM.gov record shows no set-aside, but the solicitation says it is run through the HUBZone program, so a non-HUBZone firm may be ineligible.
This acquisition is being conducted via the Small Business Administration's HubZone program.
- Unfunded requirement. The Government may not award until money is available, so you could spend bid effort and bonding costs without an award.
This is currently an unfunded requirement with a high expectation that funds will be available.
- Bid bond and performance/payment bonds. A bid guarantee is due with the offer and bonding clauses are listed; small firms need surety capacity of this size before they bid.
Submit Standard Form 24, Bid Bond duly executed between the Offeror and the bonding
- Pre-proposal site visit. The solicitation points to Section L for a site visit; if it is mandatory, missing it could rule you out, and the details were not in the readable text.
for information regarding a pre-proposal site visit
- Heavy proposal with past performance and key personnel. Four non-price factors outweigh price, and past performance needs reference questionnaires returned by your clients before the deadline, so newer firms may struggle.
- Road closed, limited work hours, possible hazardous materials. The road closes during construction, work is generally Monday to Friday 8 a.m. to 5 p.m., and the specs include a hazardous materials abatement section, which can affect schedule and cost.
The road will be closed to the public during construction.
