STANUARUJZE:D SPECIFICATION
for
CIVIL ENGINILEHlNG CONSTRUCTION

HE : STRUCTIJML ALUMINlUMWORK

1. SCOPE
1.1 This specification covers the manufacture, fabrication, assembly, and erection of structures using
structural aluminjum elements that have been designed in accordance with SABS 0160, Section HE of Part 3
of SAAS 0120, and CP 118.
NOTE: The standards referred to in the specificat.ionare listed in Appendix A.

2. INTERPRETATJON
2.1 SUPPORTING SPECIFICATIONS. Where this specificat.ionis required for a project, the following
specificatioris shall, inter alia, form part of the contract document:
a) Project specification;
b) S A W 1200 AH, SAAS 1200 A , or SABS 1200 AA, as applicable.

2.2 APPLICATION. This specification contains clauses that are generally applicable to Structural
aluminiumwork. Interpretations and variations of the specification are set out in Portion 2 of the
project specification which precedes this specification in a contract document.

2.3 DEFINITIONS AND ABBREVIATIONS. For the purposes of this specification, the definitions and abbreviations
given i.n SABS 1200 AB, SABS 1200 A , or SARS 1200 AA, as applicable, and the following definitions shall
apply:
Anodized. Descriptive of an aluminium surface that has been converted by electrochemical means to a film
that consists mainly of aluminium oxide.
Condition (Temper condition). An alphabetical cl.assification of the thermal and mechanical treatment to
which an alloy is subjected during manufacture and processing (see BS 1470 or BS 1473 or BS 1474).
Defect. Any irregularity that results from a design, material, fabrication, erection, or other fault and
that may have a detrimental. effect on the stability or function of a structure.
Designation (of an alloy). An international 4-digit classification for alloy compositions (see BS 1470
or BS 1473 or BS 1474 or SAHS 712).
*ection authora. An institution or'its representative appointed by the Employer or the Engineer or,
If so ordered, by the Contractor.
Mill finish. The surface finish that exists after completion of the process of extruding a section or
rolling a plate.
Non-strength member. A secondary part of a structure that does not carry the most important loads and is
not fully stressed, e.g. a ladder, a pipe support, a handrail.
Normal temperature. A temperature that is higher than IS OC but not higher than 32 O.
Service condition. A condition descriptive of the severity of corrosion expected in service.
Significant surface. The part of a surface to which the specified properties apply.
Strength menher. A primary structural member designed to carry important and calculated loads.

3. MATERIALS
3.1 GENERAL. A l l aluminium sections, sheet, plate, and fasteners shall. be manufactured from the applicable
alloy specified on the drawings that detail the sizes of members.
The Contractor shall not depart from the specified requirements because of the non-availability of any
item or for any other reason without the prior approval of the Engineer.
Special care shall be taken of each element of the structure during handling, transportation, and storage
to prevent undue scratching or other damage. Structural elements or their protective coatings which, in
the ophion of the Engineer, are excessivcl.yscratched may be rejected by the Engineer and, if rejected,
shall be replaced at the Contractor's own expense.

3.2 MATERIAL FOR EXTRUDED AND WROUGHT STRUCTURAL MEMBERS. In addition to Complying with the applicable
requirements of 3.1, extruded and wrought structural members shall comply with the requirements of
BS 1474 for material of the designation and the condition given i.n the project specification.

3.3 PLATE, SHEET, AND STRIP. Plate, sheet, and strip shall comply with the requirements of BS 1470 for
material of the designation and the condition given in the project specification.

3.4 CORRUGATED SHEETS. Corrugated and troughed sheets shall comply with the relevant requirements of
SABS 903.

3.5 RIVETS AND BOLTS. Rivets shall he manufactured from stock complying with the requirements of BS 1473
for material of the designation and, when relevant, the condition given in the project specification.
Where practicable, aluminium bolts, washers, and nuts shall be of the same alloy as the members to be
joined but where bolts, washers, and nuts of the said alloy are not available, they shall be of
a) alloy designation 62610 or 6082 or 5083, as applicable, or such other alloy designation as is given in
the project specification, and shall comply with the applicable requirements of SABS 712 or RS 1473; or
b) electroplated steel.
Electroplated steel bolts, nuts, and washers shall have an electroplated coating of nickel plus chromium
that complies with the requirements of SABS 728 for the service conditions stated in the project
specification and threads shall he coated to the thickness required in terms of BS 3382.
Fasteners of other materials shall be used only where shown on the drawings or required in terms of the
project specification or where their use is specifically approved by the Engineer.

3.6 WELDING CONSUMABLES. Welding filler wires shall comply with the relevant requirements of BS 2901.

4. PIANT
4.1 PLANT. Plant and equipment used for site fabricatj.on and for site erection of structures shall comply
with the requirements of the Factories, Machinery and Building Work Act, 1941 (Act 22 of 1941) and the
Mines and works Act, 1956 (Act 27 of 1956), and shall have enough capacity to ensure that the structure
is placed in its final position without distortion or undue stressing of members.
Pneumatic equipment shall be provided by the Contractor for riveting operations.

7. TESTING
7.1 TEST CERTIFICATES. Where so ordered or required in terms of the project specification, test certificates
or cast analysis certificates, or both, pertaining to the aluminium alloy to be used shall be supplied
to the Engineer by the Contractor.

7.2 TEST PRKEDIJRES ANI) ACCEPTANCE. Test procedures and the acceptance tests on the structure shall comply
with the relevant recommendations of CP 118.

8. MEASUREMENT AND PAYMENT

8.1 GENERAL
8.1.1 Basis of Measurement. Work involvjng structural aluminium members and plate work will be measured by the
mass of aluminium. Claddinq will he measured by the area covered and sundry items will be measured by
the number, mass, or area, dependinq on the nature of the item. (See also 8.1.3.)
Unless otherwise stated, gussets will be measured on the basis of the minimum enclosing rectangle.

Structural aluminiumwork

8.1.2 Repetitive work. Where there is considerable repetition of articles of the same description and mass
(e.g. towers, masts, ladders, frames, etc.) that are measured by mass, the number of such articles and
the mass or length, as applicable, of each will be stated in the schedule.
8.1.3 Basis of Mass Calculation. The mass of structural aluminium work will be calculated on the basis of the
nominal mass/unit length as stated in the manufacturer's handbook or, where not so stated, the mass will
be calculated from an aluminium density of 2 700 kg/m3. The mass of fittings such as cleats, gussets,
battens, and stiffeners will be added to the mass of the members.
Tolerances for rolling margins and other permissible deviations will be neglected for the purposes of
mass calculation.
No deductions will be made for holes for fasteners o r for milling or planing and no additions will be
made for rolling margin, waste weld metal, or shop fasteners.
