#.1.1. The sie of !angers and supports shall be in compliance with the contract specification, documents, and appro&ed shop drawings. #.1.2 !angers and supports of mechanical system shall be fabricated at factory from the appro&ed and gal&anied steel sheet roll. #.1." To ensure that all !angers and supports material are fabricated form the appro&ed, worker  Shall take photo picture on the appro&ed material for record, before starting any fabrication process. /hen the finished parts deli&ery to site, the *ngineer0s shall check the quality and material used, by the 3 labels together with the e&idence of the photo picture or refer to shop drawing , on the material been used in the fabrication. #.1.# 4nly the site engineer0s final appro&ed !angers and supports shall be used for the site installation works. #.1.5. 6arious hanger systems and components for system shall be used and shall be 3oordinated with the ceiling work at the 3ontractor option with the appro&al by the Mechanical engineer. #.1.7 %ll flanged 8oints shall be pro&ided with suitable gasket as appro&ed type by the *ngineer. #.1.9 Supports shall be attached to e&ery system using screws or bolt to pre&ent slippage and noise. #.1.:./all or o&erhead supports shall be anchored to structure using bolts of suitable type and adequate sie or other methods suitable for conditions or materials encountered, only as appro&ed by the *ngineer. #.1.;. Supports insulation work will be mentioned on method statement for mechanical system insulation work.
