SHN can assist in construction projects of any size, from residential pavement testing, to unique and complex nuclear plant decommissioning.  We work with construction firms ranging in size from small family-owned businesses to multinational corporations ranked in the Top 100 by Engineering News Record.  We provide site civil design, special inspections, materials testing, surveying, geologic investigations, drainage and stormwater runoff design and compliance, and environmental assessment and remediation.  

Our safety program and record meet the very stringent requirements needed when working in construction zones.  Construction firms and contractors know that SHN regards safety as an extremely important component of the job.  Our staff knows that health and safety is critical to SHN’s sustainability, values, and mission.

Our special certification inspectors carry multiple certifications, and when on the job site, they recognize when additional testing may be needed.  They consult the construction engineer, carry the equipment necessary to perform additional inspections or on-site materials testing, and thus can eliminate delays in waiting for soils and material testing technicians to arrive.
