Stop disturbance first
Pause work around suspect material. Do not collect a sample, sweep debris or use a photo or building age to identify material.
Safety-first project routing
Do Not Disturb Suspect Material—Plan the Next Document
Start with a stop-work boundary, define the project, separate assessment, laboratory and abatement roles, and build the document path before work.
Stop-work chain
Every safe project starts with the next document
Move forward only when the preceding role and record supports the proposed disturbance.
Planned disturbance
Define exactly which areas and materials the project may affect.
Assessment + laboratory
Connect competent assessment, controlled sampling, custody and laboratory results.
Scope + closeout
Crosswalk the inventory to work areas, controls, waste and required closeout evidence.

One property. Six distinct questions.
Start with the page that matches the uncertainty you need to resolve—not a preset solution.
01
Before renovation
Prepare project scope, records, assessment questions, laboratory dependencies and report outputs before renovation or demolition disturbance.
Open guide →02Roles & documents
Separate assessor or surveyor competence, sampling, chain of custody, laboratory analysis, result interpretation and inventory outputs.
Open guide →03Abatement scope
Normalize inventory basis, work areas, controls, occupancy, waste, monitoring roles, changes and closeout records.
Open guide →04Strata & occupancy
Organize records, authority, occupants, access, work-area separation, schedule changes and document control in occupied properties.
Open guide →05Verify licensing
Record current contractor licensing evidence, legal names, scope, checked date, expiry and regulator questions without copying a static roster.
Open guide →06Quote checklist
Compare prerequisite reports, quantities, roles, controls, occupancy, changes, waste, clearance boundaries and records.
Open guide →Decision file
Build a clearer project record
Define the planned work
Write down exactly what may be cut, removed, penetrated or demolished and where. Assessment scope depends on planned disturbance.
Separate roles and outputs
Map who assesses, who samples, which laboratory analyzes, who prepares the report, who performs abatement and who provides any monitoring or clearance evidence.
Build the document sequence
Connect the assessment or survey, sample record, laboratory result, inventory, abatement scope, work records, waste documents and closeout evidence without skipping prerequisites.
