Refer to the General Requirements section, clause 1. In either of the above cases, make available to the ITA the following: a. All requested documentation and a detailed programme to allow the ITA to discharge its duties and to witness significant stages in the fabrication and erection process. Any instruments or other equipment required checking the accuracy and quality of the works.
Design Drawings Drawings showing the dimensioned layout of the steel structure with the size and material grades of all members, the forces to be developed in their connections and any cambers etc, from which shop drawings are made. Drawings showing all necessary information to fabricate the structural steelwork, including the piece markings with the b.
Shop 6 Version 1. Reaming Faying Surfaces location in the structure.
Forming, shaping, tapering, or enlarging a hole with a reamer. Surfaces which are tightly or closely fitted. Design the connections based on forces given in the design drawings.
For hot rolled hollow sections, rectify the surface imperfections and defects revealed during surface preparation in accordance to BS EN Clause 6. Ensure compatibility between welding consumables and parent materials used for the steelwork. Ordinary nuts are to comply with BS grade 4 for grade 4.
For galvanised or sherardised bolts use class 10 nuts for 8. Black steel washers are to comply with BS Section 2. Comply with BS grade 8 for grade 8. BS for general grade bolts b. BS for higher grade bolts 10 Version 1. Comply with BS Grade 4 for grade 4. Grade 8 for grade 8. Class 10 for galvanised or sherardised grade 8.
Diameter and nominal length as noted on the drawings 3. Comply with BS RE3 for cast steel grit. Proprietary grouts are not to contain high alumina cement.
Mark completed components in locations that will not be covered up by other material after erection to avoid confusion. Hard stamping may be used other than where specified in the PSD. Keep areas of steelwork free of all markings where so required on the Drawings. Keep clean and do not allow water to accumulate on components. Protect steel against corrosion. Ensure individual piece markings are visible when members are stacked. Cut and shape steel by sawing, shearing, cropping, nibbling, plasma or laser cutting and thermal or flame cutting.
Thermal cutting are not permitted at the areas indicated in the PSD. Flame-cut edges that are free from significant irregularities require no further treatment other than dressing as specified in 4.
Drill, punch, plasma or laser cut and thermal or flame cut round holes for fasteners. Thermal holing or full size hole punching are not permitted at the areas indicated in the PSD. Drifting to align holes may be used provided it neither enlarges nor distorts the holes.
The tolerance on distortion of the punched hole does not exceed that specified; b. The holes are free of burrs which would prevent solid seating of the parts when tightened; c.
The thickness of the material is not greater than 30mm, nor greater than the diameter of the hole being punched; d.
In spliced connections when the holes in mating surfaces are punched in the same direction and the splice plates marked to show the assembly faces, if packed separately. If holes are drilled through components that are clamped together not intended to be separated after drilling, removal of burrs is not required. After the process is complete, visually inspect all welds within the area of curving or straightening. Carry out non-destructive testing of welds, where directed.
Use a plate or heavy duty washer under the head and nut where the members being connected have oversize or slotted holes. Re-tap nuts, if necessary, to ensure satisfactory tightening. Secure nuts used in connections subject to vibration or reversal of stresses to prevent loosening.
If not specified on the drawings, include the proposed method in the erection details. If there is a remaining gap more than 2mm, which may affect the integrity of the joint, take the joint apart and insert a pack of the same steel material. Place the hardened washer under the nut or head being turned.
If there is a remaining gap, take the joint apart and insert a pack of the same steel material before continuing tightening. Demonstrate by calculation that the connection is adequate for the specified forces.
Ensure the faying surfaces of friction grip joints are free of distortion, deformities or contaminants, which may reduce the slip factor below the design value. If not specified on the design drawings, show the proposed method on the shop drawings.
Temporary Welds and Tack Welds 4.
Remove the temporary welds unless otherwise agreed by the SO. Make flush the surface with the original surface after the removal. Tack welds are subject to the same quality requirements as the final welds, with the following exceptions: a.
Preheat is not mandatory for single-pass tack welds which are re-melted and incorporated into continuous submerged arc welds. Discontinuities, such as undercut, unfilled craters and porosity need not be removed before the final submerged arc welding.
Tack welds, which are incorporated into the final weld, are to be made with electrodes meeting the requirements of the final welds and are to be cleaned thoroughly.
Multiple-pass tack welds are to have cascaded ends. Remove tack welds, which are not incorporated into the final weld, unless otherwise agreed by the SO.
Remove after use where required by flame cutting or gouging at a point not less than 3mm from the surface of the parent metal. Grind flush and inspect the area visually. Where the parent metal is more than 20mm thick, check by magnetic particle testing method inspection using the acceptance criteria stipulated in Clause 5.
Do not remove temporary attachments by hammering. The trial is to use the materials and procedures proposed for the works.
Test a minimum of ten studs in the trial.
During the work, at the commencement of each shift, each welder is to undertake a minimum of two trial welds. Under this test the weld is to show no visible signs of cracking or lack of fusion. Do not straighten any studs so tested. Where defective studs are removed check the surface as specified in 4. Do not make permanent connections between members until the structure has been sufficiently aligned, levelled, plumbed and temporarily connected so that members will not be displaced during subsequent erection or alignment of the remainder of the structure.
Carry out all site welding in accordance with clause 4.
