The Sectors We Serve

Archaeology & Cultural Resources

Tremaine provides full-spectrum cultural resource management grounded in regulatory expertise and practical field experience. We help clients identify, evaluate, and protect cultural resources efficiently, integrating archaeological insight with modern data tools to reduce risk, delays, and unnecessary ground disturbance.

Subsurface Imaging

We deliver non-invasive subsurface imaging solutions that reveal what lies below the surface before excavation begins. Using advanced subsurface imaging methods, we support informed decision-making for cultural, environmental, agricultural, and infrastructure projects—saving time, cost, and adverse impacts on projects.

Starting a Project? Ensure Cultural Resource Compliance.

Understand how heritage management laws—especially NEPA and the NHPA (Section 106)—apply to your projects, funding sources, and permit pathways. We’ll clarify what triggers review and how those obligations vary by scope, location, and funding.

Then we’ll map the required studies and consultations (SHPO/THPO and tribal engagement), define the documentation standards you must meet, and embed compliance into design and construction. The result: fewer delays, better cost control, and defensible outcomes for your sector.
