Before the visit: establish the objective
We confirm the address, property type, reason for testing, areas involved, planned disturbance and deadline. Photos and construction documents can reveal important scope questions before arrival.
On site: identify materials and homogeneous areas
The inspector evaluates accessible suspect materials and groups materials that appear uniform in texture, color, installation and application. Different layers, repairs or installation periods may require separate consideration.
Representative bulk samples
Samples are collected from locations selected to represent the material or homogeneous area. Sampling is documented, and minor sample points are sealed when practical.
Chain-of-custody and laboratory analysis
Sample identifiers must match the inspection record and chain-of-custody. The independent laboratory analyzes the submitted bulk materials using the selected method and issues analytical results.
The final report
A useful report identifies the client and property, purpose and limits of inspection, material descriptions, sample locations, analytical findings, inspector credentials and applicable limitations. Laboratory results should be attached or clearly incorporated.
Understand what the inspection does not cover
Inspection conclusions apply to the scope and materials evaluated. Concealed, inaccessible or excluded areas should not be treated as cleared. If the construction plan expands, the inspection scope may need to expand too.
