Inspection and test plan

What an inspection and test plan is

An inspection and test plan, often called an ITP, is a structured quality document for a work package. It lists the required checks, test methods, acceptance criteria, responsibility, hold points and records.

Why it is useful

A checklist says what to check. An ITP also says when, by whom, against what criteria and what evidence must be kept. That makes it stronger for high-risk work such as concrete, waterproofing, MEP rough-in, roof drainage and commissioning.

Practical ITP fields

• Work step or activity.
• Inspection or test required.
• Acceptance criteria or reference.
• Responsible party and witness requirement.
• Hold point or witness point.
• Record, photo or certificate required.
