Who can bid (4)
- Open to all firms: the notice is full and open competition with no set-aside program. SAM.gov does not list a set-aside.
- Hold a current, active System for Award Management (SAM.gov) registration when the proposal is submitted.
- Submit a bid bond (Standard Form 24) or other suitable bid guarantee with the proposal.
Show all 4Show fewer
- Not have helped design or write the specifications for this project, as a prime or consultant. Such firms and teams that include them will not be considered.
How to submit: Email only, to Contracting Officer Tim Burger (timothy_burger@ios.doi.gov), Contract Specialist Kristin Tauber (Kristin_tauber@ios.doi.gov) and CS_DSC_Proposal_Submission@nps.gov. What to include is under Full summary below. Check the solicitation's instructions on SAM.gov.
Things to watch (9)
- Serious: Bid bond with the proposal, then performance and payment bonds. A project over $10 million needs a surety (bonding company) that will issue a bid bond now and performance and payment bonds after award.
- Worth checking: Wastewater plant experience bar for you and your subcontractors. Factor 1 asks for comparable plant projects, a prime role self-performing at least 40% of cost, and separate narratives for the key process and civil subcontractors.
- Worth checking: Currently unfunded requirement. The Government expects funds but will award only if and when they become available, so an award may be delayed or may not happen.
Show all 9Show fewer
- Worth checking: Liquidated damages of $5,856.43 per calendar day. Finishing late costs this amount for each day of delay, on a remote site with winter weather, access limits and long-lead equipment.
- Worth checking: Key trade firms are locked in at proposal. You must name the firms for process, mechanical/plumbing, electrical and civil work, and changing them later needs the Contracting Officer's approval.
- Minor: Taxes must be in your price. Federal, state and local taxes must be included in the proposal because the project is not tax exempt.
- Minor: Notice to proceed date differs between documents. Section H assumes a notice to proceed by February 1, 2027, while Amendment 0002 changes the assumed date for the Factor 2 schedule to April 1, 2027. Ask the Contracting Officer which date governs completion.
- Minor: The site visit was Sep 16, 2026. Check the notice and its amendments for whether attendance was required, and whether another visit is offered.
- Minor: Email-only submission with size caps. A proposal sent any other way is not accepted, so large files must be split across several emails.
