Annex F(Clause 23.16)

General Recommendations for Steelwork Tenders and Contracts

F-1 General

F-1.1 The recommendations given in this annex are in line with those generally adopted for steelwork construction and are meant for general information.

F-1.2 These recommendations do not form part of the requirements of the Section and compliance with these is not necessary for the purpose of complying with this Section.

F-1.3 The recommendations are unsuitable for inclusion as a block requirement in a contract, but in drawing up a contract the points mentioned should be given consideration.

F-2 Exchange of Information

Before the steelwork design is commenced, the building designer should be satisfied that the planning of the building, its dimensions and other principal factors meet the requirements of the building owner and comply with regulations of all authorities concerned. Collaboration of building designer and steelwork designer should begin at the outset of the project by joint consideration of the planning and of such questions as the stanchion spacing, materials to be used for the construction, and depth of basement.

F-3 Information Required by the Steelwork Designer

a) Site plans showing in plan and elevation of the proposed location and main dimensions of the building or structure;

b) Ground levels, existing and proposed;

c) Particulars of buildings or other constructions which may have to remain on the actual site of the new building or structure during the erection of the steelwork;

d) Particulars of adjacent buildings affecting, or affected by, the new work;

e) Stipulation regarding the erection sequence or time schedule;

f) Conditions affecting the position or continuity of members;

g) Limits of length and weight of steel members in transit and erection;

h) Drawings of the substructure, proposed or existing, showing:

1. levels of stanchion foundations, if already determined;

2. any details affecting the stanchion bases or anchor bolts;

3. permissible bearing pressure on the foundation; and

4. provisions for grouting.

NOTE— In the case of new work, the substructure should be designed in accordance with the relevant standards dealing with foundations and substructure.

j) The maximum wind velocity appropriate to the site (see Section 1 of Part 7 ‘Construction Management, Practices and Safety, of the Code); and

k) Environmental factors, such as proximity to sea coast, and corrosive atmosphere. Reference to bye-laws and regulations affecting the steelwork design and construction.
