NAICS 237110 – Water and Sewer Line and Related Structures Construction encompasses the design, installation, rehabilitation, and maintenance of potable water distribution systems, sanitary and stormwater sewer networks, pumping stations, manholes, catch basins, and associated conveyance infrastructure. This sector supports critical public health and environmental compliance objectives through the construction of buried pipelines, trenchless technologies, and hydraulic structures that integrate with municipal, federal, and tribal water resource systems. In the federal contracting landscape, this NAICS code serves as a foundational component of infrastructure resilience initiatives, often tied to environmental remediation, facility modernization, and disaster recovery programs under the jurisdiction of multiple federal agencies. Top contractors in this space include AAECON GENERAL CONTRACTING LLC, DAP CONSTRUCTION MANAGEMENT LLC, ASPEN CONSTRUCTION COMPANY, MAVERICK CONSTRUCTORS, LLC, PHOENIX GENERAL CONTRACTORS, LLC, SEPTECH ATL LLC, VSGI LLC, ELBOW GREASE ENTERPRISES, LLC, and KLEINFELDER, INC. These firms range from specialized small businesses with niche expertise in trenchless rehabilitation to larger primes with multi-disciplinary civil engineering capabilities, reflecting a competitive landscape that values technical proficiency in pipe lining, directional drilling, and corrosion-resistant material applications. The Department of Veterans Affairs, Department of Defense, Department of Agriculture, Department of the Interior, Department of Labor, Department of Justice, and Department of Homeland Security are the primary federal buyers. Demand is driven by the need to upgrade aging infrastructure on military installations, VA medical campuses, national parks, rural water systems, and federal detention or correctional facilities, often under mandates for sustainability and regulatory compliance. The market presents consistent opportunity density due to the aging national water and sewer infrastructure and ongoing federal investment in climate-resilient utilities. Contractors with proven experience in ANSI/AWWA standards, ASTM material specifications, and federal construction regulations such as the Davis-Bacon Act are well-positioned to compete effectively in this technical and compliance-heavy sector.

ACC002 Utilities and InfrastructureThe U.S. Army Corps of Engineers, Alaska District, is seeking market intelligence through a voluntary Request for Information to gauge industry interest and capability for the Phase I of the Utilities and Infrastructure Fighter Town Recapitalization at Joint Base Elmendorf Richardson, Alaska. This multi-hundred-million-dollar project involves massive civil earthworks totaling approximately 10 million cubic yards, installation of a new 20 MVA electrical substation, comprehensive utility networks for over 25 future buildings, and construction of heavy-duty airfield pavements, a dedicated airfield lighting vault, and a new POL tank farm with truck fill stand. The acquisition will be executed under Other Transaction Authority (10 U.S.C. § 2808a) using a Construction Manager at Risk (CM@R) delivery model, distinct from traditional contracting, to enable flexibility in adopting innovative construction technologies and fast-track execution. The estimated total project value ranges between $400 million and $600 million, with a phased approach beginning with preconstruction services and transitioning to construction upon agreement on a Guaranteed Maximum Price. Respondents are expected to provide detailed insights into their technical capabilities, particularly regarding innovative materials and methods that could enhance resilience, reduce cost, or accelerate delivery, as well as their prior experience with OTAs and CM@R processes. The government is specifically interested in understanding how collaborative preconstruction engagement, open-book pricing, phased bonding, and flexible payment milestones can improve outcomes on large-scale infrastructure in challenging environments like Alaska. Key questions address risk allocation, compensation structures if the project “off-ramps” before construction, data rights ownership, long-lead item procurement strategies, supply chain constraints in the region, and subcontractor integration models. The Alaska District is evaluating whether the CM@R-OTA combination offers advantages over traditional procurement and seeks feedback on bonding timelines, funding gap mitigations, and market conditions that may affect responsiveness. All responses must be submitted by July 24, 2026, to the designated points of contact, with no obligation or reimbursement provided to participants, and participation does not guarantee future eligibility for a solicitation.

A critical component involves routing a reducer from 2.5-inch to 2.0-inch Schedule 80 PVC beneath the tramway for an 88-foot run, followed by two tee connections branching off to 1.5-inch Schedule 80 PVC lines serving potable water access points next to the tramway’s highest pins, spaced about 87 feet apart. Each access point must include an upward-facing bleed valve, a cut-off valve, and a downward-facing 1.5-inch NPT thread adapter. Contractors must coordinate with the local city water utility to ensure water shutoffs do not exceed a single workday and are responsible for verifying all existing site conditions, clearances, and dimensions prior to quoting. This is a total small business set-aside under NAICS code 237110, and all offerors must be actively registered in SAM.gov.

The award will be based on the lowest priced technically acceptable response, with past performance evaluated for relevance, quality, and timeliness—those without relevant experience will receive a neutral rating. Site visits are strongly encouraged, and potential bidders should contact Chief Anthony DeLorenzo to arrange access to the facility. The solicitation, issued as a Request for Quotation under FAR Part 36, includes applicable Department of Labor wage rates and excludes payment and performance bonds. All responses must be sent to Joel Ivy by the specified deadline, and visual references provided in the scope of work must be thoroughly reviewed as they govern the understanding of required work.
