Who can bid
This is a Total Small Business Set-Aside, meaning only small business concerns as defined by the Small Business Administration may submit bids and be awarded this contract. For NAICS 237110, the size standard is typically based on average annual receipts over the past three years; see the current SBA table of size standards to confirm your eligibility.
You must be registered in SAM.gov (System for Award Management) with active status, have a valid Unique Entity Identifier (UEI), and be registered in the Dynamic Small Business Search (DSBS) if you want to be considered. If you are a Veteran-Owned Small Business (VOSB), Service-Disabled Veteran-Owned Small Business (SDVOSB), HUBZone small business, Women-Owned Small Business (WOSB), or 8(a)-certified firm, you may have additional advantages in future Corps opportunities, but for this total set-aside, any qualifying small business may compete.
How to put together a competitive bid
Verify your bonding capacity. Sewer construction projects typically require bid bonds (usually 5-20% of bid price) and performance and payment bonds once awarded. Contact your surety early, as Corps projects often have specific bonding forms and requirements.
Review Davis-Bacon Act requirements. Federal construction contracts require payment of prevailing wages; obtain the applicable wage determination from the solicitation and factor these rates into your labor estimates.
Account for Corps-specific specifications. Army Corps projects use Engineer Technical Letters (ETLs), Unified Facilities Guide Specifications (UFGS), and often EM 385-1-1 safety requirements. Your safety plan and accident prevention plan will likely be evaluated.
Evaluate site conditions. Atchison, Kansas, sits along the Missouri River with varied topography. Plan for mobilization, dewatering, traffic control, and coordination with local utilities—common challenges in urban storm sewer separation.
Price carefully. Lump-sum or unit-price bids for this type of work carry significant risk for underground conditions. See the solicitation for the pricing structure and geotechnical data availability.
Past performance matters. The Corps evaluates recent, relevant experience. Highlight comparable municipal or federal sewer/stormwater projects, especially those of similar scale and complexity.
