Abatement oversight & clearance
Somebody independent has to say the work is finished. Cadence monitors abatement while it happens and performs the visual inspection and clearance sampling that closes it out — with no financial interest in the removal contractor's schedule.
Why it can't be the abatement contractor
The contractor doing the removal has an interest in the answer. That isn't an accusation — it's structural, and it's why clearance is conventionally performed by someone who isn't them. A clearance signed by the firm that did the work carries less weight with an owner, an insurer, or a regulator than one that didn't.
Cadence performs no abatement. Whatever the air samples say, my invoice is the same.
During the work
- Pre-abatement walkthrough and containment review before work begins
- Area air monitoring outside containment while removal is underway
- Personal air sampling where exposure documentation is required
- Daily observation logs and photographs
- Notification of conditions that need addressing before they become a stop-work
Clearance
Clearance is two things, and both have to pass. First a thorough visual inspection of each functional space, confirming the work is genuinely complete and there is no residual dust or debris. Then aggressive air sampling per the procedures in Appendix A to 40 CFR 763 Subpart E.
Which analytical method applies depends on the project. Small-scale work can clear by phase contrast microscopy below 0.01 fibers per cubic centimeter under 763.90(i)(5); larger projects clear by transmission electron microscopy against the statistical comparison in 763.90(i)(3). I'll tell you which one your project needs before it starts, not after.
What you receive
A clearance report documenting the visual inspection, sample locations, volumes, analytical results, and a clear statement of whether the area passed. Written to satisfy the owner, the permitting authority, and whoever inherits the building file in ten years.
Independent by design
No abatement, no remediation, no referral fees. The only thing Cadence sells is the finding.
How it's priced
Oversight is billed by the day or half day rather than as a fixed fee, because the duration is set by the abatement contractor's schedule, not mine. Air sample analysis is passed through. You'll have the rates in writing before the first day.
Also relevant
If the survey hasn't been done yet, that comes first — it's what the abatement scope is built from.

Abatement scheduled?
Tell me the scope, the contractor, and the dates. Oversight books up around demolition season, so earlier is better.
