INSPECTION TEST PLAN

Inspection Test Plan (ITP) adalah document quality yang harus disiapkan oleh fabricator sebelum proses fabarikasi, construksi, dijalankan.

Berikut ini adalah step step bagaimana membuat dan menyiapkan sebuah ITP dalam pekerjaan consturction fabrication :

Step 1
Read the contract documents (including the technical specifications) and prepare a list of any discrepancies, ambiguities, missing information and standards of materials and/or workmanship that it is considered are inappropriate.

Step 2
Contact the customer and resolve the issues listed as a result of Step 1.

Step 3
Examine the scope of work and divide it into separate areas requiring an Inspection and Test Plan (where not already prescribed in the contract documents). As a general guide it is normally most convenient to document a separate Inspection and Test Plan for each trade or work area/section.

Step 4
Note the Hold and Witness Points required by the customer (including as listed in the contract documents).

Step 5
Review the contract documents again and note the requirements that have the most impact on the quality of the finished work. For each ask the question “What will be the consequences if it is not made sure this is right?” Be certain to include any references to tests, submitting information to the customer, obtaining approvals and Hold and Witness Points.

Step 6
Determine from Step 5 which items or aspects of each inspection will need to be recorded on checklists and prepare these.

Step 7
Discuss the checklists with those directly involved with the work and obtain their input. This input should particularly be directed at identifying those issues that have caused problems (and involved extra costs) in the past, and therefore warrant checking at the earliest opportunity to avoid unnecessary and costly rectification.

Step 8
Prepare each Inspection and Test Plan to reflect the requirements of the contract documents. Reference the ITP in the Quality Management Plan and cross-reference to the other related ITPs.

Step 9
Issue each Inspection and Test Plan and/or associated certification to the customer for consideration within a reasonable period prior to commencing the work described in the Plan and adjust them to suit any comment received (or act as otherwise required in the contract documents).

Step 10
Decide how best to divide the whole of the work into work areas for control purposes and indicate these locations either on a schedule (with reference to grids and levels) or by marking up drawings.

Step 11
Prepare and issue checklists for each work area and identify them according to location.

Step 12
Train those directly involved with each of the ITP in their use. Formalise a procedure for the notification of Witness and Hold Points to the appropriate person(s).

Step 13
Carry out inspections and tests in accordance with the Inspection and Test Plans, provide notices to the customer and/or regulatory authorities for Hold or Witness Points, as designated or applicable, and record the results on checklists.

An Inspection and Test Plan identifies the items of materials and work to be inspected or tested, by whom and at what stage or frequency, as well as Hold and Witness Points, references to relevant standards, acceptance criteria and the records to be maintained. Inspection and Test Plans, when properly implemented, help ensure that, and verify whether, work has been undertaken to the required standard and requirements, and that records are kept.
