For torque wrenches used in the first step of the combined method these requirements are modified to ± 10 % for the accuracy and yearly for the periodicity. Checking shall be carried out after any incident occurring during use (significant impact, fall, overloading etc.) and affecting the wrench. Burrs, loose material and excessive thickness of paint that would prevent solid seating of the connecting parts shall be removed before assembly If a bolt assembly has been tightened to the minimum preload and is later un-tightened, it shall be removed and the whole assembly shall be discarded. Bolt assemblies used for achieving initial fit up should not generally need to be tightened to the minimum preload or un-tightened, and would therefore still be usable in location in the final bolting up process. NOTE: If the tightening process is delayed under uncontrolled exposure conditions the performance of the lubrication may be altered and should be checked The supervisor shall ensure torqueing is properly carryout as per specified sequences at prescribed torque values the project flange management procedure. 9

ERECTION

9.1

General

This clause gives requirements for erection and other work undertaken on site including those relevant to the suitability of the site for safe erection and for accurately prepared supports. Work carried out on site which includes preparation, welding, mechanical fastening and surface treatment shall comply with the Clauses 6, 7, 8 and 10 respectively. Inspection and acceptance of the structure shall be performed in accordance with the requirements specified in Clause 12. 9.2

Site conditions

The project manager is responsible to ensure that all the site for the construction works complies with the technical requirements with respect to the safety of the works the erection.

Access routes to the site and within the site should be given on a site plan showing dimensions and level of access routes, level of the prepared working area for site traffic and plant, and areas available for storage. If the works are inter-linked with other trades, technical requirements with respect to the safety of the works shall be checked for consistency with those for other parts of the construction works. 9.3

Erection method

The project manager is responsible for any kind of lifting/erecting and he shall ensure all the components/structural items are ready and site are is ready for erection. Prior to lifting all the engineering drawings with proper sequence of lifting/erection and necessary design/load, center of gravity calculation are performed. Simple/ uncomplicated lifts/erections which most of them are performed on a regular basis utilizing fixed, dedicated lifting equipment. Essentially this type of lift consists of routine crane or rigging operations within the yard (e.g. loading plate lines and cutting lines, unloading steel from lorry or trailer, moving items in fabrication shops using plate clamps and slings, erection of pipes on the erection area, etc.) or lifts/erections involving the use of basic hoisting equipment but not requiring specialist rigging skills (e.g. use of certified lifting equipment suspended from dedicated lifting points such as pad eyes or runway beams to handle a piece of equipment). The use of generic task risk assessments and toolbox talks is adequate for this level of lifting operation. For complex Lifts/erections call for the lifting operations to be carried out within areas of restricted access or close proximity to unprotected parts of the facility structure. This requires lifting operations of a non-routine nature which call for specialist advice, and planning or other special conditions. These lifts, as listed below, require a separate Method statement/ rigging arrangement prepared by the concerned fabrication yard. Weather conditions and forecasts (wind speed, tide, sea conditions etc.) shall be monitored for such lifts. The areas of Complex Lifts shall be identified as exclusion zones and cordoned off when a lift is carried out. The execution of these operations must not deviate from the rigging arrangements and any associated method statement where applicable. Complex Lifts shall be covered by Task Risk Assessment (TRA) sessions. Prior to making the lift, all personnel involved shall be thoroughly briefed as to their duties and responsibilities, via a documented Tool Box Talk. The superintendent or supervisor / Sub Contractor (if the rigging is done by Sub Contractor’s, then they have to include their TRA) will issue a method statement and lift plan and drawing plan in accordance with the “Lifting Procedure”. A minimum of two (2) days prior to the Complex Lift coordination meeting shall be conducted. The method statement/lifting plan distribution shall include Project Manager, Construction Superintendent, Rigging Superintendent and HSE Manager. Refer to Safe Rigging and Material handling Procedure Prior to the task taking place an inspection will be undertaken on all of the associated activity equipment, rigging and general area by each concerned PIC or his nominee involved in the activity. On verification of compliance to the procedure, drawing and Rigging & Lifting Risk Assessment concerned HSE personnel will sign off Risk Assessment allowing the activity to proceed. Page 18 of 24

GEOMETRICAL TOLERANCES

11.1

Tolerance Types

The following types of geometrical tolerances shall be follow during steel structures fabrication, assembly and erection as applicable. a) Essential tolerances: Dimensions for those applicable for range of criteria that are essential for mechanical resistance and suitability of the completed structure. b) Functional tolerances: Dimensions for those required to fulfill other criteria such as fit-up, pre assembly and appearance. In addition, special tolerances may be specified either for geometrical deviations already defined with quantitative values or for other types of geometrical deviations. If special tolerances are required the following information shall be given as appropriate: a) Amended values for functional tolerances already defined; b) Defined parameters and permitted values for the geometrical deviations to be controlled; c) Whether these special tolerances apply to all relevant components or only to particular components that are specified. In each case, the requirements are for final acceptance testing. If fabricated components are to form parts of a structure that is to be erected on site, the tolerances specified for the final checking of the erected structure shall be met in addition to those for the fabricated components. a)

Essential Tolerances

Essential tolerances shall be in accordance with BS EN 1090-2 Annex D.1. The values specified are permitted deviations. If the actual deviation exceeds the permitted value, the measured value shall be consider as a non-conformity.

FACTORY PRODUCTION CONTROL SYSTEM MANUAL

Rev. 0

In some cases there is a possibility that the uncorrected deviation of an essential tolerance can be justified in accordance with the structural design when the excess deviation is included explicitly in a recalculation. If not, the nonconformity shall be corrected. b)

Functional Tolerances

Functional tolerances in terms of accepted geometrical deviations shall be in accordance with one of the following two options: a) The Tabulated values b) The alternative criteria If no option is specified by designer or purchaser the tabulated values shall apply Tabulated values: Tabulated values for functional tolerances shall be followed as per BS EN 1090-2 Annex D table D.2. Generally values for two classes are shown. The choice of tolerance class may be applied to individual components or selected parts of an erected structure. NOTE How D.2 can be applied would be to invoke tolerance class 2 for part of a structure to which a glazed facade was to be fitted, in order to reduce the amount of clearance and adjustability required at the interface. If tabulated values are used, and the choice of class is not specified by design or purchaser, then tolerance class 1 apply. Alternative values: If specified the following alternative criteria may be applied a)   b)

Welded structures, the following classes according to EN ISO 13920 apply: Class C for length and angular dimensions; Class G for straightness, flatness and parallelism; Non-welded components the same criteria as in (a);

c) In other cases, for a dimension d, a permitted deviation ± Ll equal to the greater of d /500 or 5 mm is allowed. Where full contact bearing is specified, the fit-up between surfaces of erected components shall be in accordance with Table D.1 after alignment. For bolted splices shims may be used where the gap exceeds the specified limits after initial bolting-up, to reduce the gaps to within the permitted deviation, unless otherwise specified in. the execution specification. Shims shall be used at any point. If necessary, the shims may be held in place by means of either fillet welds or a partial penetration butt weld extending over the shims.
