6.0 HSE All work shall be carried out in accordance to AGIP KCO and Renco-KAT safety regulations & policies. Team coordination shall be implemented by the work supervisor. Crane should be transported across cleared construction site with dropped boom. While lifting a structural steel element, swing and rotation must be prevented with tag line. In the case of adverse weather conditions (snowfall, fog or rain), and in poor visibility as conditions lifting operation will be stopped. Lifting operation shall not be carried on during electric storms. Lifting operation shall stop when wind velocity exceeds 10 m/s or as per risk assessment. All personnel related to work shall wear PPE. Stop signs will be provided to warn vehicles, when required. Valid certification of all lifting equipment will be verified prior to operation. Certified and color coded rigging gear shall be used. When working at height (height more that 1,5 m. from ground level), safety belt shall be fixed to a safety life line, fixed on beams or a rigid steel element. All heavy transport and plant to be fitted with audible reverse alarm. Wind speed meter to be provided. Work area to be barricaded. Rigging study/lifting plan to be approved for non-routine and critical lifts.

When manlifts are used, no person will be allowed to exit the manlift to get onto the structure.

All manlifts, and other plant and equipment shall not be allowed to moved unless assisted by a landsman.7.0 MATERIALIt should be ensured that the material is approved for use and the certificates are available. The fabricated structure should be stored on wooden logs above flat and solid surface free of water deposition. All other materials shall be transported and stored before execution of work in the manner to prevent any defect to the physical or chemical quality of them and according the safety procedures.The area of operation where erection is ongoing will be barricaded as per safety rules.

All materials (steel components, bolts, nuts, washers) shall be in accordance with the requirements of the applicable specifications and drawing requirements with regard to type, grade and required certification. Fasteners and small fittings shall be stored in dry conditions. 8.0 WORK SEQUENCE8.1 Welding:

The steel structure is free issue from Company and The welding shall be limited to piping supports and/or modifications as required by the construction drawings or COMPANY direction. If welding is required in such manner, it shall be performed only after the thorough removal of the paint.

Welding in the field shall conform to the related codes and standards as well as to the corresponding drawings. All parts to be welded shall be clean of paint, rust and other materials that may affect the welding.

After the completion of the welding, all slag and spatter shall be removed from the welded area. Visual inspection shall be carried out to ensure that weld is visually acceptable and weld profile is adequate in accordance with approved welding procedure and specification. NDT to be performed in accordance with WPS.

The welding shall be performed in line with the approved & applicable welding procedures and the welders shall be qualified to the ASME IX code and/or local regulations. 8.2 Pre-Erection:

Before erection works start, the concrete surfaces of the foundations shall be scabbled, cleaned and checked by the Renco-KAT QC Inspector. Surveyors shall also check the coordinates and levels of these foundations and paint the marks on the foundations denoting these axis and levels. These target marks shall be colored red/white to facilitate their visibility. Structural steel may be erected in individual pieces or in pre-assembled in transversal as rigid sections, which have been assembled on the ground. The dimensional (KE01-A0-000-KD-C-SP-0008-000) checks shall be carried out on beams, columns, base plates, cross members, etc. of these pre-assembled sections by foremen and spot checks shall be made by the Renco-KAT QC Inspectors. Preliminary tightening of all bolts used for the pre-assembly shall be carried out using appropriate hand tools. The work permit shall be taken before starting of the erection work.8.3 Erection:

All structural steel shall be erected in accordance with the AFC (Approved for Construction) of the erection drawings.

By means that no activity shall be done before AFC issued drawings received to site.

Anchor bolts and connection points shall be inspected for damage.

The erection of the steelwork shall not start until the concrete foundations and slabs have cured as specified by the relevant specifications and obtained minimum requirement of concrete strength at 28 days.

The methods of lifting and fixing shall be determined so that the members are not damaged during the handling process. The structural components shall be lifted by means of mechanical lifting equipments. During erection, all work shall be securely bolted, however no permanent bolting and welding shall be done unless the correct positioning and alignment of the member has been obtained. All completed work shall be within the required dimensional tolerances and all materials shall be free of twists or distortions that are likely to affect the structural integrity.

All the members shall be checked about damaged paint and if required, touch-up paint shall be done as per specifications.

It shall be checked to ensure that the correct bolt type as indicated by the manufacturers stamp is used and the bolt length is correct.

Friction surfaces shall not be painted and adequate protection shall be provided during the painting of the structural element at the workshop or at the site before the erection.

Columns shall be positioned on the concrete foundations, with the nuts on the fixing bolts left loose. These nuts shall be tightened using electric operated or manual wrenches and special care shall be taken to provide surfaces that are free from loose mill scale, dirt, oil, burrs or any other defect which would prevent tight sealing.

Nuts and bolts shall also be left loose for beams that are assembled between two structural steel columns. After this fit- up, the positioning shall be checked, and if required, adjustments shall be made in order to obtain the required tolerances and the nuts and bolts shall be permanently tightened.

Each part of the structure shall be aligned as soon as possible after it has been erected. Permanent connections shall not be made between members until sufficient sections of the structure have been aligned, leveled, plumbed. After ensuring that members will not be displaced during subsequent erection or alignment of the remainder of the structure, permanent fixing will be done. Fixed elements shall be braced to each other safely.

Tolerances for out of plumb and levels shall be as specified in the specifications and drawings. After the alignment and bolting of the steel structure, but before grouting, all anchor bolts and nuts shall be tightened while the shims are checked with regard to their tight fit. After the hardening of the grouting compound, the anchorage shall again be checked and, if required, the nuts shall be tightened once again. 8.4 Tightening of the bolts:

Bolts shall be tightened to bring the surfaces together using a normal effort with a podger spanner or power wrench.

After bringing the bolt and nut to the right position by normal hand power, Bolts and Nuts positions shall be marked with identification marks visible showing the reference to the steel structure. Marking will be done by non-erasable type marker.

The bolt shall be turned 2 quarters of one full rotation against the tightened nut by a long moment arm wrench.

9.0 QUALITY ASSURANCE AND CONTROL PROCEDURE

Request for Inspection (RFI) shall be submitted to QA/QC section prior to commencing the erection work. The Engineer in-charge in collaboration with the QC Section shall inspect all the necessary requirements prior to erection work, thus ensuring the readiness of the work. Check all Applicable Documents & Specifications if available & approved. Inspection of Tools and Equipment. Check all materials required for the work. Check application as the work progresses.
