TYPICAL PERFORMANCE SPECIFICATIONS
DESIGN REQUIREMENTS
1. As scope and performance documents, the drawings and specifications
do not necessarily indicate or describe all the work required for the performance and completion of the work. Contractor
shall furnish and install the items required for proper completion of the work without adjustment to the price.
Work shall be structurally sound, quality construction and the Contractor shall be solely responsible for the inclusion
of adequate labor and materials to cover the proper and timely installation of the items indicated, described or
implied. This is a performance specification and criteria for the solution of structurally sound work as indicated
on the drawings and herein specified for the sole purpose of defining the design intent and performance requirements.
The details shown are intended to emphasize the acceptable profiles and general performance requirements for this
project, and the general orientation, arrangement and dimensional coordination necessary for the Contractor to
fulfill its obligations. The contractor is required to meet the intent, purpose, criteria, parameters and functional
requirements of the work described in this section. |

2. The curtain wall
system shall be AUSTVISION Spider System.
3. The glass entrance
area shall include:
- 3.1 Structural suspended tempered heatsoak tested glass, with intermediate
vertical mullions on interior and Austvision Spider fittings. The Austvision fittings are to be designed to be
flush on the exterior surface. The design of the system is the sole responsibility of the Glazing Subcontractor
and the Supplier. The system shall be designed to prevent high stress concentration at the hole positions and must
comply with all requirements of this section.
3.2 Glass thickness of façade elements and (separately) of mullion elements shall be determined as required
to meet the specified criteria and shall be uniform throughout each visually separated area except where, in the
opinion of the Architect, a thickness change will not affect either the performance or the appearance of the final
installation. Minimum glass thickness shall be 12mm for face glass and 19mm for fins, the contractor shall determine
glass thickness based on requirements of this section.
3.3 Glass systems shall be complete with all supporting steel, stainless steel cappings and framing, clamping or
fixing devices, resilient pads and separators, as well as closures, gaskets and sealants as required for a complete
installation in strict accordance with the manufacturers' instructions.
3.4 Assembled façade glass shall float within peripheral metal glazing channels. Adequate clearance shall
be provided within these channels to prevent metal to glass contact under any combination of loads and movements
including, but not limited to design wind loads, floor deflections, gravity and gravity loads of system, thermal
expansion and contraction.
3.5 Exposed metal fittings shall be manufactured from type 316 stainless steel supplied by Australian Glass Assemblies,
finished to match approved samples, and shall be designed with capability to adjust and align façade and
accommodate building movements and applied forces.
3.6 Mullion restraint boxes shall be recessed flush with the surrounding finish work. Coordinate with surrounding
finish work as required for accessibility for glazing or reglazing. Furthermore, the mullion restraint box shall
be concealed and flush with the floor level or top of concrete curb as required. Coordination with concrete work
is required.
3.7 Fasteners shall be of type 300 stainless steel, of strength and type appropriate to their use, and shall be
tightened (where necessary) to specific torques with calibrated wrenches.
3.8 All exposed metal framing, cappings, trim, closures, etc., for the glass mullion wall systems shall be clad
with or manufactured from AISI type 316 stainless steel.
3.8.1 All exposed stainless steel surfaces shall have a #4 finish or as approved by the Architect.
3.8.2 To the extent possible, cladding elements shall be shop assembled. Field measurements shall be taken where
required to assure proper fit and to minimize field joints and splices.
3.8.3 Assembly fasteners shall be concealed.
3.8.4 Components shall be designed to allow for building movements as well as thermal movements without causing
buckling, loss of flatness or finished surfaces, excessive opening of joint or over stressing of welds and fasteners.
3.8.5 Exposed-top-view surfaces which exhibit pitting, seam marks, roller marks, lack of visual flatness or "oil
canning", stains, discolorations or other imperfections on the finished units will not be acceptable.
4. Unless otherwise
defined by Contract Documents, appearance of exposed elements, including width and depth, shall be consistent throughout
project.
5. Unless otherwise
defined by Contract Documents, overall thickness of each glass type, and component thickness of multiple layer
glass types, shall be consistent throughout project.
