welded joints in completed weldments. The extent of testing shall be at the discretion of the Engineer but it is anticipated that 25% of all butt welds and 10% of all fillet welded joints shall be tested by non-destructive means. If any sample fails a specified test the consignment which it represents may be rejected in part or whole at the discretion of the Engineer. Major welds, where catastrophic collapse would follow weld failure, shall be tested 100%. The Main Contractor and Steelwork Sub-Contractor shall pay all fees involved in testing unsatisfactory welds and repaired, previously failed welds. The Employer shall pay all fees for all first time tests that are accepted as satisfactory by the Engineer. All areas of defective welding shall be cut out and made good to the entire satisfaction of the Engineer and all costs for these remedial measures shall be borne by the Main Contractor and Steelwork Sub-Contractor. The remedial work shall be deemed to include radiographical or other suitable examination to verify the acceptability of the repair. All slag shall be removed from welds to facilitate inspection. The Steelwork Sub-Contractor shall give at least three days notice of his intention to despatch any major welded component to site. This stipulation is made in order that inspection can be carried out on the weldment and analysis of test results completed prior to despatch. Non-destructive testing of welds shall be in accordance with the following British Standard Specifications:- Visual Inspection .. .. BS EN 970:1997 Radiographic Examination.. .. BS EN 1435:1997 Ultrasonic Examination.. .. BS EN 1714:1998 BS 3923 : Part 2:1974 Penetrant Test.. .. .. BS EN 571-1:1997 Magnetic Particle Test.. .. BS EN ISO 9934- 1:2001 17 WEIGHTS 76
All weights and variations or otherwise will be based on the listed weights of members and no allowance made for rolling margins. All steel sections shall be of "full profile" with no appreciable loss of material through corrosion or deficient rolling. If it is found that any steel weights less than 2% less than the listed weights, the Steelwork Sub-Contractor shall replace it with a satisfactory section. 18 CLEANING & SURFACE PREPARATION All steelwork, except where metal coatings or anti-corrosive paint treatments are to be applied, shall be thoroughly scraped and wire brushed free from dirt, loose rust, scale and grease immediately before despatch to site. Steel which has weathered to some degree may be used but heavily pitted steel, as depicted for Grade D surfaces in the Swedish Standards SIS 05 5900 shall not be used except with the consent of the Engineer. Irrespective of the steel protection system specified elsewhere the interfaces of connections where High Strength Friction Grip Bolts are to be employed shall be thoroughly cleaned as specified and the steel surfaces shall be left unpainted. Steelwork which is to be galvanised shall be flash cleaned by pickling immediately prior to galvanising. This operation shall be carried out by immersing the fabrication in a bath of warm diluted sulphuric acid or hydrochloric acid to remove all residues of millscale, rust and foreign matter. Care should be taken to ensure complete drainage of the acid from the steel on completion of the process. All steelwork to receive metal spray, or anti-corrosive paint treatment shall be prepared by grit blasting or shot blasting of the steel surface to a "Second Quality" surface cleanliness as defined in BS 7079 Part 0:1990. "Preparation of steel substrates before application of paints and related products". The surface roughness of the blast cleaned steel should not be greater than the recommended maximum amplitude of 75 microns (0.003 inch). The steel surface profile may be further limited by the paint manufacturer's requirements and these shall be accepted as forming part of this specification.
