Carstensen Contracting Inc. specializes in civil infrastructure construction, with core capabilities centered on heavy and civil engineering projects under NAICS 237110. The firm delivers site preparation, earthwork, grading, drainage systems, and roadway construction services, leveraging precision earthmoving equipment and project management methodologies tailored to public works requirements. Their technical expertise includes compliance with DOT standards, stormwater management systems, erosion control protocols, and utility coordination during large-scale earthwork operations. Key differentiators include field-proven proficiency in rural and remote site execution, adaptive scheduling under variable weather conditions, and a focus on safety-first operational discipline. While no specific award history is available to detail project scope, the company’s primary NAICS classification indicates sustained engagement in public infrastructure development requiring robust field engineering and regulatory adherence. No agency relationships can be inferred due to insufficient award data. The absence of recent contract records prevents identification of federal, state, or local agency partnerships or recurring project types. The company’s industry focus is narrowly aligned with heavy and civil engineering construction, which encompasses the building of highways, bridges, dams, water and wastewater systems, and other public works infrastructure. Their market positioning is rooted in execution of physically demanding, logistically complex projects requiring heavy machinery, surveying precision, and coordination with public works departments. Carstensen Contracting Inc. is a small, locally based entity structured as a 2L (small business), headquartered in Dell Rapids, South Dakota. The company holds no federal certifications and operates primarily within the regional construction market, serving infrastructure needs across the Upper Midwest with a hands-on, field-oriented operational model.

Harbel, Inc. is seeking MBE, DBE, and WBE subcontractors and suppliers for a targeted green-street retrofit project in downtown Romney, West Virginia. The project involves the construction of approximately 343.59 linear feet of South Marsham Street between Gravel Lane and US Route 50. The scope of work includes the installation of 1,450 square feet of permeable pavement, eight vegetated stormwater management cells, and necessary drainage, underdrain, inlet, pipe, tie-in, and downspout work. Additionally, the project requires limited curb, sidewalk, ADA, apron, crossing, and traffic-calming improvements to integrate the BMP corridor, as well as the planting of six native trees and approximately 345 native plants. The goal is to treat approximately 1.7 acres of impervious surface within a 3.3-acre drainage area, concluding with final stabilization, cleanup, and restoration. This solicitation is open to various small business concerns, including veteran-owned, service-disabled veteran-owned, HUBZone, disadvantaged, woman-owned, and minority-owned businesses. To accommodate the project scale, these entities are encouraged to form consortiums if individual bid items are too large for a single firm to handle.

Interested parties should contact Jonah Leith or Jennifer Wilson for further details and must provide a response indicating their intent to bid.
