Project lifecycle
How the projects in this portfolio were delivered
Each case study below moved through the same lifecycle — scoping, field investigation, data, deliverable, and regulatory closure.
Step 1: Site reconnaissance
Days 2-5
Field staff walk the site, log conditions, and interview operators so the scope reflects what is actually there.
Step 2: Sampling & analysis
Week 2
Soil, groundwater, vapor, or air data is collected and run through accredited laboratories with documented chain of custody.
Step 3: Sealed deliverable
72-hr priority option
You receive a signed, ASTM- or agency-compliant report with findings, costs, and clear next steps.
Step 4: Filing & closure
We submit to the reviewing agency, answer comments, and carry the file through approval or no-further-action.
Our portfolio
Every project type, from screening to closure
Due diligence, remediation, geotechnical, and civil site work across industrial, commercial, and municipal properties — each engagement documented end to end.
How we finish
Remediation carried through to regulatory closure
We design the cleanup, manage the field work, and drive the file to a No Further Action or closure letter so your transaction or build can move forward.
