INTRODUCTION Fabrication division fabricates structures for various clients. Fit up and assembly is an important activity for fabrication of structure. In order to ensure that effective functioning of a quality system requirements are fulfilled, there is a need to establish a quality system involving the functions of fit up and assembly and to ensure the activities are in controlled condition.
2.
PURPOSE The purpose of this procedure is to establish a documented procedure for fit-up and assembly of structural steel to ensure that the specified quality requirements are fulfilled with international quality system and to ensure continuos process stability and to achieve the customer need in time.
3.
SCOPE This procedure is applicable to all the activities related to fit-up and assembly of structural steel at structural fabrication shop
On receipt of the drawings, priority schedules from planning ( through e-mail/ transmittal ) through DCC .
8.2 8.3
Contractor to withdraw material from stores as per MIN received. a) Physical verification of raw material shall be carried out before issuing the raw material to Engineer (CNC). If any discrepancy was found PE shall raise MDR (Material Discrepancy Report) / FOR (Field Observation Report ) / SER (Site Engineering Request) b) Preparing material cutting requisition format No. 2SF FMT ME041 and same shall be hand over to Engineer (CNC) for pre-fabrication i.e., cutting and drilling operations to be
performed by Lead Engineer (CNC). 8.4
Preparing additional requirement of material if any required and same shall be forwarded to Material Controller through e-mail.
8.5
PE (Fit & Assembly) shall co-ordinate with Engineer (CNC) for availability of semifinished material after cutting and drilling.
8.6
Normally PE (Fit & Assembly) shall receive pre fabricated material / steel from machine shop and verify the mark number and material specification (Identification of material specification for plates other than IS 2062 and ASTM A36 shall be done ) with drawing number and ensure the compliance before proceeding for further work. But in
drawings or applicable project specifications to ensure full penetration. If fit-up is found acceptable, PE (Fit & Assembly) shall release the fit-up for welding by signing the inspection report format no. 2 QA FMT ME 003.One copy inspection report is handed over to QMD engineer , one copy inspection report with sub-contractor and one copy sent to planning for updating. After updating the copy shall be retained back from planning. 8.11
In case the fit-up is not found to be acceptable, it shall be rectified and re-inspected
8.12
PE (Fit & Assembly) shall co-ordinate with contractor
equipment/machine
and welding consumable
for getting
welding
if it is not under the scope of sub
contractor. Arranging Qualified welder as per the applicable qualified WPS is under sub contractors scope. 8.13
Control of welding process activities shall be taken by Welding engineer as per
procedure No. 2 SF QSP GE01 1. Weld visual inspection, NDT examination shall be conducted by QMD Engineer as per the requirements of Inspection and test plan and shall release the structural members, if there is no final assembly of the members involved. 8.14
In case of final assembly of the parts is required to be done as per the production
plan/drawings, PE (Fit-up & Assembly) shall review the Assembly drawing and list out all member required for assembly and check-up the Inspection and test status of the members with QMD. Only accepted structural steel members shall be taken-up for assembly.
