Method statements and ITPs explained
Both are submitted to the consultant and approved before the work starts. The method statement is for the crew. The ITP is for the inspectors.

Method statement review
Choose a method statement. Read it as the consultant's reviewer and click every paragraph that contains an error or a dangerous gap. Then submit your review to see what you found, what you missed and what you flagged wrongly.

ITP builder
Load a template for a system, then set the intervention for each party. Click a cell to cycle H → W → R → S → -. The checker flags critical steps without a consultant hold or witness, and ITPs with so many hold points that the job will crawl.

4D hold point simulator
Your ITP drives a simple programme. Each activity takes the days shown. At a hold point the crew waits for the notice period and the next inspection day. At a witness point they give notice but keep working. Change the settings and compare with "every step a hold point".

A drywall partition from framing to finish. Move through the stages. The hold point is before the boards go on. Turn on x-ray to see what an inspector would have caught, and what is hidden forever if the wall is closed without one.
