Structural Steelwork The design of all structural steelwork shall be such as to provide a robust and rigid structure requiring the minimum of maintenance and providing a long service life. In the design of steel structures, due cognizance shall be taken of environmental and wind load conditions as specified in the main, specification. The design of mobile structures shall be such that the induced von Mises stress (effective stress in triaxial loading) will rot exceed 90% of the elastic limit strength of the steel when the equipment is travelling at maximum speed and colliding with either other stationary equipment or fixed stop blocks. In calculating von Mises stresses, due cognizance must be taker of stress concentrations, If the elastic limit strength of the steel is not known, it will be determined by using a 0.5% strain offset on the stress- strain curve of the material. Where applicable, the design may be in bolted, riveted or welded box construction except that no site welding will be permitted in the final erection at the port except with the approval of TNPA Alternatively, a welded hollow section lattice type structure will be acceptable, subject to the following requirements:

The members must be structural sections made from BS 4360/SANS 50025 grade S355JR / 430 weldable structural steel - Welded for sizes up to and including 110mm outside diameter (BS 1775 HFW) - seamless for sizes over 110mm outside diameter (BS 1775 HFS).

Tube wall thickness must not be less than 4mm.

All Joints must be completely seal welded In accordance with BS 5135. Special care must be taken to prevent the ingress of moisture into hollow section members by ensuring that each member is airtight.

Alternatively, the Noxyde paint system can be used, consisting of two to three coats of water based Noxyde paint to achieve a DFT of 350 to 400 microns. Where the Noxyde system is used on areas other than slightly corroded structural areas, the following additional requirements must be observed:

Very smooth surfaces (e.g. 3CRI2, stainless steel or hot-dip galvanized components, bolts, nuts and fittings, and HT bolts): Parts must be thoroughly degreased using OptiDegreaser, washed down with potable water, and immediately when dry, a single costar OptiprimeAqua applied. Paintable flexible sealant/mastic: Only sealant approved by the paint manufacturer may be used, and an initial coat of OptiPrimeAqua applied over it before the further coats of Noxyde are applied. Bolted / riveted connections: After blasting or and/or cleaning as required, apply a coat of OptlPrimeAqua and an additional stripe coat of Noxyde, in contrasting colour, to all bolt/nut and plate edges and crevices.

The adhesion of old coatings must be verified by doing a cross cut adhesion test on selected areas.

The compatibility of the new paint system on the old coating must be tested and guaranteed in writing by the paint supplier.

The work and coating system must be guaranteed for a minimum of 12 months.

All heavily corroded areas must be shot blasted to minimum SA2 and the three coat system indicated in the table above ―Maintenance Painting of Structures‖ applied.

Areas where the old coating is still sound need only be high pressure cleaned with a suitable solvent and coated with one of the primers suggested in table above (as tie coat) and then with one of the top coats suggested to get the appropriate color and finish. The minimum dry film thickness of this tie coat must be 75 microns and top coat must be 50 microns, but the previous coating color shall be completely obliterated to present a uniform color.



Note: Inorganic zinc primers shall not be re-covered with an Inorganic primer, but only with an organic zinc primer.

Repairs to the insides of all the enclosed sections of the booms as well as the Insides of the crane legs, sill beams, cross beams, p4on cross bracing members etc. shall be done as above but the top coat need not be applied.

Contract Program.



5.6.2 INITIAL PROGRAM, CONTRACT PROGRAM AND SUBSEQUENT REVISIONS

The Contractor shall submit a program within 2 weeks of the date on which he was notified of

having been awarded the contract / order.

Any program submitted which does not supply all the documentations set out in clause 31.2

is deemed to be rejected, whether or not the Project manager does so in writing.

This Initial Contract Program, hereinafter referred to as the "Initial Program", shall be drawn

up at the level of detail necessary in the opinion of the Project Manager to ensure effective

control over the work, usually to Level 4 detail.

A "Summary" or "ham-mocked" program shall be submitted with the Initial Program. The

summarized activities shall be inserted in such a way that the Milestone Dates as well as

major interfaces of services and/or other contracts logically required for the completion of the

contract shall be clearly shown. The start and finish of the summarized or ham-mocked

activities shall be clearly indicated on the detailed network.

Unless stated to the contrary, the Project Manager will examine and comment on the Initial

Program within 2 weeks of submission and the Contractor shall amend and submit this

program, hereinafter referred to as the "Contract Programme" for approval within a further

period of 5 days.

The Project Manager may not in every instance be able to provide all information or working

drawings, where applicable, of every aspect of the works but such non-availability will not be

deemed to be an excuse for non-presentation of programs. In such instances the relevant

part of the program should be based on the Contractor's best estimate with a statement on

which assumptions or drawings it is based.

Should the Project Manager so require, or should problems occur during the execution of the

contract, the Project Manager might request that portions of the program be expanded to

enable closer control to be exercised e.g. site construction and commissioning programs. In

such cases the more detailed networks shall fit exactly into the logic and time span of the

Contract Program, but may be presented as separate programs.

Minor revisions to the Contract Program may be introduced from time to time by mutual

agreement. Should the Project Manager require a major revision to the Contract Program,

such revision will be specified to the Contractor in writing.



The Project Manager shall specify the date by which the Contractor shall be required to

submit the revision in question. This date shall not, unless otherwise agreed, be less than 2

weeks from the date of notice.

Revised Incidence of Payment schedules shall be required based on the revised Contract

Program. These revisions shall be made when changes occur in this program and must be

updated every month to include actual payments.

Should the Contractor require a major revision affecting the logic or dates of the program,

such revision will be specified to the Project Manager in writing for approval before the

revision is performed.

A revision to the program does not invalidate the "Date of Completion" in terms of the

General Conditions of Contract and as given in the appropriate schedules. Changes to these

dates can only be effected through a contract amendment.

Progress shall be monitored against the latest revised program and payments controlled by

the latest revised Incidence of Payment Schedule accepted by the Project Manager.
