    6.0 PROCEDURE / METHOD TO BE EMPLOYED:

    6.1 OFF-LOADING AND PHYSICAL INSPECTION OF STEEL STRUCTURE MEMBERS

    · The Engineer shall ensure that, before off-loading the supplied structural steel material, the lay-down area is as reflected on the approved site layout drawing. The lay-down area should be level and clear from any obstruction.
    · Plane, level and compacted timber pieces of 50mm x 50mm in size shall be placed under the structural steel members.
    · All supplied structural steel members shall be off-loaded 5m away from the building limits.
    · Purchase Order documentation provided by the structural steel supplier shall be verified and off-loading safety precautions should be observed.
    · Material Packing List shall be verified against items being off-loaded.
    · Physical Inspection of the steel members shall be carried out to verify Quantity and Quality.
    · Cases of Non-Conformance of the supplied structural steel members and accessories shall be reported to Project Engineer.
    · A mobile crane and/or a forklift shall be used to off-load the supplied materials.

    6.2 STAGGING AND GROUND ASSEMBLY

    · Main frame columns shall be marked and moved to their respective locations.
    · Main frame rafter pieces shall be laid on the ground along their respective grid line.
    · Roof purlins related to each bay shall be laid along their respective rafters.

    6.3 PAINTING SEQUENCE

    · We propose SIGMA painting system subject to approval. However, we can submit any other Supplier (Jotun, Hempel, National) to the satisfaction of the Consultant.
    · Surface Preparation: All primary steel members will be shot blasted to Swedish SA 21/2 cleaned and painted with one coat - 50 microns DFT of Epoxy primer (Sigma 7412) at Steel Factory.

    Ø Secondary Surface Preparation at Site

    o Degrease the structural member surface with suitable alkali degreaser if necessary.
    o Clean the surface by the use of fresh water jet.
    o Roughen the surface with emery paper for better adhesion.


    Ø Painting System at Site

    o Apply one under coat of 7682 Sigma Cap Coating EP – Off-white (as per the approval) at 100 microns thickness.

    Ø DFT by Airless spray
    o Roughen the surface with emery paper.
    o Apply one intermediate coat of 7682 Sigma Cap Coating EP at 75 microns DFT by Airless spray.
    o Roughen the surface once more with emery paper.
    o Apply one Finish coat of 7688 Sigma Cap Finish EP at 75 microns DFT by Airless spray.
    o NOTE: All corners, sharp edges, nuts, bolts and weld seams should be stripe coated by brush application with the same material as the consecutive coat of the system to achieve the specified dry film thickness. Giving more attention to these areas will extend the life of the maintenance system.

    6.4 THE ERECTION SEQUENCE

    · Before any erection starts, the Engineer shall review erection drawings to determine which bays require permanent bracing.
    · Start erection of columns from the braced bay using guy wires and ratchet pullers for stability of frames during erection.

    · Raise rafter into position at top of columns.
    · Hold rafters in place with hoisting equipment while the required bolts are installed through the column connected splice place, and tightened properly.
    · Using above procedure assemble second rafter and place it on top of second set of columns.
    · Bolt-up to columns and continue to hold second rafter until both rafters are braced by roof purlins.
    · Install permanent bracings between rafters.
    · Before proceeding further, a Theodolite shall be used to check if the structure is plumb and square.
    · Temporary braces shall be used to align and plumb the columns if further alignment is required.
    · Resume erection of columns, rafters and purlins in succeeding bays in the same manner as above.

    · Use a string line projected away (by 65mm) from the eave strut to establish the correct distance and line.
    · Start at the eave and work up the roof towards the ridge from both sides of the building and both slopes finishing with the ridge panel.
    · Provide bead mastic over the panel corrugations along panel end laps.
    · Make sure that the panel ribs are kept in a straight line from eave to ridge.
