MARK E JOHNSTON CONSTRUCTION LLC

MARK E JOHNSTON CONSTRUCTION LLC specializes in civil infrastructure construction services, with a primary focus on heavy and civil engineering projects under NAICS 237110. The firm delivers site preparation, earthwork, grading, drainage systems, and utility coordination for public works and government-funded infrastructure. Their technical expertise includes compliance with federal construction standards, erosion and sediment control measures, and adherence to DOT and Army Corps of Engineers specifications. The company’s operational approach emphasizes precision in earthmoving, material testing, and project sequencing to ensure structural integrity and regulatory alignment on public projects. Award history does not provide sufficient detail to identify specific agencies or project types, so no definitive agency relationships can be confirmed. The absence of recent award data limits the ability to characterize recurring client engagements or project patterns. The contractor’s primary industry focus is heavy and civil engineering construction, encompassing the design-build execution of transportation-related earthworks, stormwater management systems, and public facility site development. This places them in the infrastructure support segment of the federal and state capital improvement market, where experience with geotechnical constraints and environmental permitting is critical. The business operates as a small, privately held entity structured as ZZ, with no active government certifications on record. Located in Campton, New Hampshire, the firm maintains a regional presence in the Northeast, positioning itself to support state and municipal infrastructure initiatives. While lacking formal socio-economic certifications, the company leverages local expertise and hands-on field experience to deliver durable, code-compliant construction outcomes in challenging terrain and climate conditions.
