Services
Environmental Consulting
Our environmental consulting services assess and mitigate ecological impacts throughout project lifecycles. We specialize in regulatory compliance, air permitting, and environmental planning for transportation and infrastructure projects. Leveraging decades of data and proprietary intelligence, we identify risks early and develop sustainable solutions that align with client goals while ensuring adherence to federal and state requirements.
Geotechnical Engineering
Geotechnical engineering services evaluate subsurface conditions to inform foundation design and construction planning. Our experts conduct site investigations, laboratory testing, and slope stability analyses to address challenges in diverse terrains. This critical data helps clients avoid costly delays and ensures structural integrity for infrastructure, commercial developments, and energy projects across varied geological landscapes.
Construction Materials Testing
Construction materials testing verifies quality and compliance of building components during project execution. We perform field and laboratory testing on concrete, asphalt, soils, and aggregates to meet specification requirements. This service ensures structural performance, identifies potential issues early, and maintains quality control throughout construction phases for transportation, industrial, and commercial applications.
Facility Engineering
Facility engineering optimizes building performance through mechanical, electrical, and plumbing (MEP) system design. We address energy efficiency, code compliance, and operational improvements for healthcare, federal, and commercial facilities. Our solutions extend asset lifecycles while reducing environmental footprints through innovative design and retrofitting strategies tailored to client-specific needs.
Site Selection
Site selection services identify optimal locations for development projects through comprehensive feasibility studies. We evaluate environmental constraints, zoning regulations, infrastructure capacity, and geotechnical factors to minimize risks. This data-driven approach helps clients make informed decisions about land acquisition and project viability while streamlining permitting processes.
