For asbestos surveyors

The asbestos survey app
that pins every sample
to the floor plan.

MasterPlan is a mobile asbestos survey tool. Sketch the floor plan, drop a pin at each sample location, log material type, friability, and condition, attach photos and audio, then generate a PDF report — without leaving the site.

Asbestos surveyors, on site, on the phone

Whether the job is a pre-purchase survey, a pre-renovation check, a pre-demolition survey, or a re-inspection of known asbestos-containing materials, the field workflow is the same: walk the building, find suspect materials, sample, photograph, and document. MasterPlan handles every piece on your phone.

Pre-purchase & due diligence

Identify and document suspect materials before a sale. Generate a clean PDF for the buyer or solicitor.

Pre-renovation surveys

Identify ACMs in the work area before contractors disturb them. Pin every sample to the affected zones on the floor plan.

Pre-demolition surveys

Comprehensive identification across the whole building. Multi-floor plans and offline-first capture for inaccessible areas.

Re-inspections

Open a previous plan, update condition fields and risk ratings, generate a fresh report. Pins stay anchored to their original locations.


Every sample, every field, every photo

The asbestos survey template captures the data fields any survey methodology relies on. You bring the protocol. MasterPlan holds the floor plan, the samples, and the documentation, and produces a clean PDF.

Sample on the floor plan

Drop a pin at the exact location of each sample. Pins stay anchored to walls and rooms — move a wall, the pins move with it. Status colours reflect Presumed ACM, Confirmed ACM, or No ACM Detected at a glance.

Material identification

Capture material type from a curated list — insulating board, sprayed coating, pipe insulation, cement, floor tiles, textured coatings, gaskets, and more. Asbestos type: chrysotile, amosite, crocidolite, or pending lab confirmation.

Condition assessment

Record friability (friable / non-friable), overall condition (good / fair / poor / damaged), extent of damage, and surface treatment (encapsulated, painted, unsealed). All structured data, all on the pin.

Risk and action

Tag each sample with a risk rating (low / medium / high / critical) and a recommended action — manage in place, encapsulate, monitor with re-inspection, or remediate. Your call, captured on the pin, included in the report.

Lab tracking

Log the lab sample reference that matches your chain-of-custody form. When the lab returns results, update the lab-result field per pin — chrysotile detected, amosite detected, mixed ACM, or no asbestos detected. The PDF reflects the current state.

Photos & voice notes

Photograph each sample location and mark up the photo with arrows, rectangles, or text labels. Dictate notes hands-free — Whisper-quality speech-to-text runs entirely on your phone, no server upload.
