Newington College – Sesquicentenary Building Project

The new curtain wall at Newington College

G.James has recently finished work on the Sesquicentenary Building Project at Newington College in Bankstown, Sydney. The bulk of this project comprises two new combined buildings – The Lawrence Pyke Science Centre and The Tony Rae Resources Centre Library. The project was designed by Budden Nangle Michael & Hudson Architects, and builder A W Edwards was contracted to construct it.

Foyer to the building.G.James’ work on the project comprised the design, supply and installation of windows, doors, curtain walls, glass walls, glass canopies, a glass greenhouse, aluminium cappings and soffits– utilising our 850-500, 651, 451, 475 and 476 Series frames. Jockey sashes from our 150 Series were required for most windows, and some windows also featured curved heads. G.James’ Sydney Commercial Façades division carried out the work on this project.

Noise Reduction

Acoustic laminate was used extensively throughout the project to minimise disruption to classes from external noise. Typically 12.76mm acoustic laminated glass was used externally and 10.76mm clear Low E coated ccoustic laminated glass was used internally in jockey sashes and internal skins. This was an important consideration as Newington College sits directly below the approach flight path into Sydney Airport with approaching aircraft flying very low directly above the school.

Curtain Wall Glazing

Curtain wall glazing.Four “curtain wall” sections were defined by the Architect and included in G.James’ scope of work. Two of these were fabricated as 850-500 Series structural glazed curtain walls. The Stair glazing used the 850-500 Series structural glazed frame as a window wall fitted between steel horizontal supports. Coloured back glass was used to infill between the frames and hide the steel. Jockey sashes and secondary frames were used behind these frames to create large cavities for acoustics. On one curtain wall an additional 850 Series frame was used as an internal frame to provide the nominated 400mm airspace.

Dual skinned Curtain Wall

The most prominent feature of the building is the final curtain wall  – pictured at the top of this post. This is a dual skinned arrangement with the outer skin built out from the building by a metre with three horizontal steel trusses. The glazed height of this wall is approximately 9.4m and is glazed with pieces of glass each approximately 4.7 m high by 2m wide – weighing a hefty 300Kg. This glass is supported by glazing channels top and bottom, and also by 15mm annealed glass fins vertically. The internal glazing skin comprises G.James’ 450 Series frame fitted with the flush face to the inside and incorporating jockey sashes fitted in-line with the fixed glass for access and maintenance. The metre wide cavity between the glass is ventilated and includes 600 mm wide horizontal and vertical automated tracking sun shades installed into this space by another contractor.

G.James has also supplied and installed soffit linings below this glazing, metre wide cappings over the cavity, and also to the other curtain walls. Several glazed awnings and a glazed greenhouse were also completed.

Official Opening

The buildings will be officially opened in July as part of the 150th anniversary celebrations at Newington College.

We are proud to announce that G.James will be manufacturing the futuristic glass and aluminium façade for the University of Technology (UTS), Sydney Faculty of Engineering and Information Technology building.

This challenging assignment will add to the growing list of landmark Australian buildings which G.James has contributed to. G.James will manufacture the curtain wall, window wall and distinctive aluminium sun shades for the project.

Manufacturing of the façade will commence in October 2012.

The Project

The UTS Broadway is a part of the UTS master plan to redefine the Ultimo campus and will house the Faculty of Engineering and Information Technology.

The design of the structure will add twelve levels of teaching & research laboratories, extra lecture theatres, seminar rooms and academic offices, while leaving ample pedestrian access through the ground level.

The striking design is described best by architects Denton Corker Marshall Pty Ltd:

The surface of each plate is creased to form a series of ‘gills’, visually reinforcing the sense of plate as skin and creating a semi-transparent screen. Further permeability is established by perforating the skin of each plate. Using the ‘1’s and ‘0s’ of binary code, the alphabetical character string for ‘University of Technology Sydney Faculty of Engineering and information Technology’ is translated and re-worked to create a perforated pattern on the skins.

The 14 level construction will be the first 5 star green rated building on campus, and has a focus on environmentally sustainable practises.

The design is intended to reduce energy requirements by 30–45% with features such as night purge ventilation, an under-floor air distribution system, and the iconic binary sunshade. Daylight and fresh air are utilised to reduce dependence on air conditioning and artificial lighting.

Current Progress

Demolition, which included the removal of three existing buildings to make room for the structure, was completed in October 2010.

Excavation for the building has now finished (over 60,000 cubic metres were removed from the site), and the first footings have been poured, as well as concrete for the car parks.

The project, expected to cost $170 million, is scheduled for completion at the end of 2013.

About the Architects

In July 2009, UTS announced the winning design, submitted by Australian architectural firm Denton Corker Marshall, from over 60 international entries.

Selected by UTS representatives, the City of Sydney, and the New South Wales Department of Planning, the design for the Information Technology and Engineering building was chosen for its aesthetic appeal, as well as its functionality and sustainable qualities.

Aluminium conveyor rollers

High Tensile Tubes

Among our extensive range of aluminium extrusions, G.James produce a range of high-tensile strength aluminium extrusions for use as roller shells. Whilst not a new product for G.James, these have been subject to increased interest due to the growing mining industry – aluminium rollers can be an excellent choice for conveyor idlers in mining applications. They are available in a range of diameters –  4″, 5″, 6″ & 7″ (101.6mm, 127mm, 152mm, 178mm), and can be cut to short or long lengths as required.

Why Aluminium?

Aluminium roller shells result in significantly lighter rollers than those using steel shells. Their relative lightness means they require less power to run, and their reduced weight decreases the likelihood of strain injuries when being manually handled.  Aluminium is also corrosion resistant – a distinct advantage when dealing with corrosive materials such as coal or salts. Although steel is a harder material, aluminium still offers great wear resistance. All good things do however come to an end – even at their end of service life, aluminium rollers have the advantage of increased scrap value compared to alternative materials.

Manufactured to fine tolerances

Given the intended application, our roller shell extrusions are manufactured to extra stringent tolerances. Our roller shell extrusions are straight to within 1mm/3000mm, and typically offer a better TIR (total indicated runout – degree of roundness)  than steel rollers. This roundness helps to reduce noise – which is an advantage in already noisy environments where OH&S places an onus on noise reduction. Manufacturing tolerances for our range of roller shells are tabled below.

External Diameter (mm) Weight (kg.m)
101.60±0.40 2.681
127.00±0.40 4.492
152.00±0.40 5.894
152.40±0.40 6.275
152.40±0.40 7.478
178.00±0.40 8.876

  • External Diameter: Distance across the tube. (measurement 1 in the diagram above).
  • Max Ovality: Maximum distortion from round – ie. the variation between the tube at its thinnest and thickest measurements.
  • Wall Thickness: Distance from the exterior surface to the interior surface (measurement 2 in the diagram above).
  • Wall Thickness Eccentricity: Difference between the thickness of the tube at a given point & the thickness at the point opposite (ie. measurements A & B in the diagram).
  • Weight: Weight per metre of roller length.
