Shop drawings
The contractor will be required to prepare shop details for the work which must be submitted to the Engineer for approval before fabrication is started. Approval of shop details by the Engineer will include the following
a) Examination of member sizes for consistency with design requirements.
b) Examination of all connections designed and/or detailed by the fabricator, for adequacy of load transference.
c) Approval of leading dimensions which are taken to include such dimensions as may influence the design (eg, depth of trusses and girders) or which may grossly affect site programme (eg, truss spans and stanchion heights).

DESCRIPTION UNIT QUANTITY RATE AMOUNT
Notwithstanding any approval of these details, the contractor shall remain responsible for ensuring that the dimensions, details and workmanship result in the correct assembly of the work
Material and workmanship
The steelwork is to be fabricated from mild steel to SABS1200H Grade 300W. The whole of the fabrication and workmanship generally is to be in strict accordance with SABS 0162‐1984 as amended. The material shall be of best quality throughout, free from loose rust or millscale, true to thickness and profile throughout and of the section and mass specified subject to a 2% tolerance for rolling margin. Consideration will be given to any detail variation which the contractor may wish to make with the view to the simplification of either fabrication, delivery or erection. Substitutions must be made at the contractor's own expense
The contractor shall provide Works Test Certificates where so required by the Architect.
Testing
The Engineer shall be at liberty to select test pieces from steelwork in the workshop or on the site and to have them tested. The expense of such tests are to be borne by the contractor if the steelwork does not comply with the standards laid down above.
Hold down bolts
Holding down bolts and other fixing devices which are to be embedded in concrete must be supplied to the principal contractor on request together with the necessary information, identification and templates.

Welding
Welding shall be in accordance with SABS 044 "Welding: Parts I, II and III" and shall be 6mm continuous fillet welds all round.
Welding shall be carried out in a manner which will prevent any distortion of the weld or the parent section.
All welds shall have adequate root fusion and shall be free from cracks, porosity or other irregularities and any undercutting shall be made good by the deposition of additional runs of weld metal.
Any completed welds showing cracks, cavities or other efects shall be cut out and made good at the contractor's own expense.
Mild steel electrodes shall comply with SABS 455 "Covered Electrodes for Manual Arc Welding of Mild Steel and Medium High Tensile Steel".
Bolts
All structural bolts shall be grade 8.8. Bolts shall have well‐formed heads forged from the solid. Nuts shall closely fit the bolts so that they can only just be turned by hand and at least one clear thread shall project beyond the nut when fully tightened. All bolts shall have one asher under the nuts and shall be so tightened that the threaded portion does not bear on the members connected. Where bolt heads or nuts bear upon bevelled surfaces they shall be provided with tapered washers of 2,3 mm mean thickness to provide a seating square with the axis of the bolt.
Friction grip bolts
Connections specifying high strength friction grip bolts are to be in strict accordance with SABS 094 "Bolted Friction Grip Joints in Structural Steelwork" and the bolts used are to be in accordance with BS 3139 Part 1 : 1959 "General Grade Bolts, High Strength Friction Grip Bolts for Structural Engineering".
Notwithstanding the above, the following must be rigidly adhered to :

b) Contact surfaces shall not be painted and shall be thoroughly cleaned free of dirt, oil, loose scale, burrs and other defects which are liable to reduce friction resistnace between surfaces.
c) At all times the correct torques shall be applied to the different sizes of bolts.
Erection
The proposed method and sequence of erection of the shall be submitted to the Engineer for written approval. Such submission is to take place at the time of shop drawing submittal. The contractor shall indicate the proposed method of propping to ensure stability of the structure during erection. Such stability during erection remains the contractors responsibility. Where temporary bracing or propping is necessary, the contractor shall be responsible for the design, erection, maintenance and removal (where necessary) of such support. Proposal of such bracing or propping shall be submitted to the Engineer at an early stage for written approval. The steelwork generally is to be fabricated in the contractor's works having due regard to transport and erection facilities. He must supply all erection tackle, temporary erection bracing, erect and plumb all steelwork and supply all steel wedges and tacks as required. Items may be detailed for delivery "piece small" or the contractor may prefabricate if he is satisfied that suitable arrangements for transport can be made.
Connections are to be designed for the forces indicated on the drawings or to the maximum capacity of the members.
Cleaning and painting
All structural steel is to be thoroughly degreased to remove all grease or oil and then wire‐brushed, scraped or sand‐papered to remove all rust, mill‐scale or surface contaminations and is to be immediately given one coat zinc chromate, allowed to dry overnight and given one coat of universal undercoat prior to delivery to site. All damaged paintwork is to be made good on site after erection is complete.
