Local delivery
What working with a regional crew looks like
Short mobilization distances mean faster site visits, quicker sampling turnarounds, and engineers who already know the local reviewers.

Step 1: Scoping call
Day 1
A licensed engineer reviews the property, your deadline, and who needs the report — lender, agency, or counsel.

Step 2: Local mobilization
Crews dispatch from the nearest office, usually on site within days rather than weeks.

Step 3: Site reconnaissance
Days 2-5
Field staff walk the site, log conditions, and interview operators so the scope reflects what is actually there.

Step 4: Sampling & analysis
Week 2
Soil, groundwater, vapor, or air data is collected and run through accredited laboratories with documented chain of custody.

Step 5: Filing & closure
We submit to the reviewing agency, answer comments, and carry the file through approval or no-further-action.
