For each activity on a construction site, there would be a corresponding Method Statement as well as Inspection and Test Plan including Checklist shall be developed.

Here is a definition of ITP:

Inspection & Test Plan (ITP) 

An Inspection & Test Plan is the program of inspection, testing of materials, and survey shall be prepared and submitted by the contractor to the Engineer for approval before usage and application to the site.

Here is a definition of Checklist

Checklist or QVD (Quality Verifying Documents) 

A list of items shall be noted or checked in a completed activity. It is always attached to the Inspection Request. To be signed by concerns parties once the inspection is approved.

Preparation, Review and Approval

Inspection and Test Plan is made and issued by the Quality Engineer, it should then be reviewed by the Quality Manager, Construction Manager and approved by Project Manager before it shall submit to the Engineer.

As it is always required by the contract or specification, Method Statement  and Inspection and Test Plan including Checklist shall be submitted to the Engineer for approval.

The QA/QC Engineer shall maintain a register of all Inspection and Test Plan (ITP) including Checklists.

The QA/QC Engineer shall maintain a complete master set of approved Inspection and Test Plan

The inspection process shall have the inspection criteria for every Inspection and Test Plan item. Here are the following:

Inspection Responsibilities or Inspection Levels:

Surveillance ( S ) = random attendance at site, no signature  required on the Inspection 

Request ( IR ) or its accompanying documentation.

Execution ( E ) = attendance at the site is a must, the signature is always on Inspection Request and Checklist.

Witness (W)  = attendance at the site is expected, the signature is required on check sheet of    Inspection Request ( IR ) and Checklist, but if the signatory is not present to sign at the time, follow on work may proceed and the document(s)  to be singed later.

Hold Point (H) = attendance at the site is mandatory and signature is required on the check sheet of Inspection Request at the time of  the inspection to release the following work.

Review ( R ) = documents to be reviewed, no signature required on the Inspection Request or its accompanying documentation.

Records (RE) = documentation to be recorded, no signature required on the Inspection Request or its accompanying documentation.

Test ( T ) = attendance is required,  signature required on check sheet of Inspection request and checklist.

The main items that need to be specified in an Inspection and Test Plan are :

·         the item that will be checked/inspected/tested (e.g. concrete strength)

·         the document that requires this item to be checked (usually it is the contract or similar document-specification)

·         the document that according to, this item will be inspected/tested (usually a standard or a statutory requirement)

·         the kind of inspection that needs to be performed (visual inspection, document approval etc)

·         the frequency that this inspection needs to be performed (e.g. for concrete slump test = once for every track)

·         the objective criteria/tolerance parameters that will determine if the inspection/test for that item has passed or not

·         the kind of document that will be prepared and saved as a record of pass or failure (usually a signed-off form, a testing machine print-out, a photo etc)

·         if this record needs to be a deliverable, meaning that it needs to be kept and handed over to the Client at the end of the Project as part of the As-Built Folders

·         the responsibilities of every party involved (Contractor, QC Engineer, Client’s Representative etc)
