STRUCTURAL STEEL WORKS – ITP & CHECKLIST

This post explains the necessary Inspections and testing required during the fabrication and installation of structural steel works. This is only a summary and a full customizable ITP with the required checklist in word format can be downloaded from the link given at the bottom

WHAT IS STRUCTURAL STEELWORK

Structural steel is one of the most important materials in the construction industry. It is used in many structures, in fact, heavy structures like buildings, factories, bridges, etc. Structural steelwork is a combination of reshaping and fabrication of structural steel through cutting, bending, and assembling into the required structural shape.

WHAT IS AN INSPECTION AND TEST PLAN OR ITP

Inspection and Test plans and checklists are integral parts of quality management systems not only in construction but in almost every industry where Quality Management systems are in place. It is considered to be master documents through which different parameters and actions of a process or activity would be monitored and recorded which play a vital part during the verification later or in simple terms during auditing.

In the construction industry, where there are a lot of activities, for a variety of trades such as structural, Finishes, Façade, Electrical, Mechanical, Plumbing, etc. are to be completed spanning across excavation for the foundation to handing over the stage, thereby Preparation and implementation of different inspection test plans form the most crucial part of the project management system.

Inspection and Test Plan For Structural Steel Works

SECTION 1 – DOCUMENTATION REVIEW

This part deals with the review and approval requirements of necessary documents needed to be completed before the structural steel works on-site is to be started. The important part is drawings including the typical details common to all the work in different areas and sections, materials as required by the project elements.

SECTION 3 – INSPECTION OF INCOMING MATERIALS

This part deals with the inspection of materials that are required for the structural steel elements. These are mainly different types of sections like beams, columns, girders etc.

The storage of materials also shall be checked whether it is followed the guidelines or standards applicable.

SECTION 4 – PRE ERECTION INSPECTION

Pre-erection inspection is important for any activity. Availability of the materials in the exact numbers as per the no and size of the structural elements are to be checked. The storage of the materials shall be checked to ensure that it is satisfactory to all parties. This stage is also divided into three stages which are inspection for materials, foundation, and other section

The important inspection points are

Check on the pre-fabricated members
Check on benchmarks
Check on foundations
Check on levels and distance of foundations.
SECTION 5 – ERECTION IN PROGRESS INSPECTION

This part deals with the points to be taken care of while the installation of structural steelwork is in progress. Some inspection points may not be on “HOLD’ during this stage and hence keen attention is required during routine site visits (SURVEILLANCE). When discrepancies/changes against the acceptance criteria are observed instruction is to be given to rectify them immediately.

The major points are

Check on column erection
Check for alignment of columns
Check on the erection of horizontal beams, girders, and vertical bracings
Check on bolting
Check on locking of packer plates
Check erection of the second piece of columns
Check for the erection of interconnecting members
Check on welders
Check on the welding machine
Check on preheating
Check on fit-up of joints
Check for assembly of welding parts
Check on post-weld treatment
SECTION 6 – POST ERECTION INSPECTION
