What is Witness Point & Hold Point?

There are two important inspection action codes in Inspection Test Plan. Few or

many had been a little confused about these inspection action codes.

The Hold point and Witness point are always found and indicated in theInspection and Test Plan.They are the construction stages which may need supplementary inspection or verification.

The purpose is to make sure specification requirements are

complied accordingly and to proceed for the following activities. So Verification

process are outlined and documented in the Inspection and Test Plan as Hold

Point and Witness Point.

Here is the best definition ofHold Point & Witness Point:

Hold Point is a mandatory verification point beyond which a work cannot

 proceed without approval by the Engineer or Consultant or Municipality Inspector.The work cannot proceed until the Engineer or Consultant is able to verify the

quality of the completed work and releases the Hold by means

of Inspection Request approval.

Witness Point is an identified point in the process where the Engineer or

Consultant may review, witness, inspect method or process of work. The

activities however may proceed.

Here are sample of Hold Point & Witness Point:

Hold Point: The first floor of our project is to be casted but it must be inspected by

the Municipality Inspector before it will be poured with concrete. The Hold Points

there is the inspection or verification of the Municipality Inspector; once

the Inspection is approved it will release the Hold.

So in short statement “The activity of pouring concrete cannot start without the

approval of the Engineer or Municipality Inspector.”

Witness Point: We were on painting activities for second coat, the Inspector just

witnessed the applications of coatings.

 “There is chance to attend an activity but does not involve obligation, the activity

can proceed without approval.”
