The Australian Steel Institute is pleased to announce the winners of the 2018 Steel Excellence Awards for NSW and the ACT.

In the Buildings (Large Projects) category, Art Storage Facility was the winner. Working in conjunction with renowned Sydney-based architects Tzannes, and builder Infinity Constructions, structural and façade engineers Taylor Thomson Whitting created a dramatic and beautiful structure to house the private art collection of a prominent Sydney-based philanthropist.

Located in Alexandria, the warehouse provides 10,000m2 of storage space, split over two levels. Around the perimeter of the Great Hall and throughout the building, steel features heavily, chosen for its aesthetics and beauty. The building delivers a state-of-the-art facility with a 100-year design life, providing exceptional opportunities for both staff and visitors to view and interact with the artwork.

CSU Student Accommodation was awarded a High Commendation in the Buildings (Large Projects) category.

In the Buildings (Small Projects) category, Manly Aquatic Centre took out the top prize. Michael Davies Architecture won the design competition—beating out 27 other proposals—set by the Manley City Council for the redevelopment of its Aquatic Centre.

The Pool Hall is split into two levels, with the lower level in the north contiguous with the outdoor pools and the upper level 1,200mm above. The upper level was also designed so that upon entering the facility, it is possible to see the lower level, as well as the entire Centre. The use of simple planning and architectural devices to modify and control the internal environment for comfort and energy saving were provided throughout.

The St Pius X High School took home a High Commendation in the Buildings (Small Projects) category.

In the Steel Clad Structures category, Willinga Park - Camp Draft Grandstand (entered by Bay & Coast Metal Roofing) was the winner. Willinga Park is an Equestrian centre on an undulating, 40 hectare coastal property. Its 483 seat Camp Draft Grandstand was constructed for the World Championship Gold Buckle in May 2018.

The Grandstand's design is focused on minimalism in detail, as well as practicality and function, connection to landscape with ingenuity, and a focus on art. It consists of three distinct components working harmoniously - the breathable base, the ribbon and the floating roof. The base is a breathable wall envelope to house services made of steel z purlins. The mid-structure is the seating wrapped with a COR-TEN ribbon that floats over the breathable wall, and the bold steel floating Aramex roof provides protection from the weather.

Entered by AEH, the Westconnex Concord Rd to M4 West On-Ramp received the top award in the Engineering Projects category. The bridge is a continuous, 5-span, 213m long twin steel composite girder bridge supported on mechanical steel pot bearings with a maximum span of 60m. It had to be designed for both vertical and horizontal curves, with a tight horizontal radius of approximately 80m. In addition, the steel girders sit on a constant 5% crossfall, while the road surface transitions from 5% to 3% superelevation. The constant cross fall means that through the horizontal curve, the bottom flange was fabricated in a conical shape.

The bridge design includes open steel troughs on straight spans, top lateral bracing on curved spans for torsional stiffness, bottom flange stiffeners with low gauge plate and use of concrete stitch pours allowed the use of steel construction without the disadvantages of welding or bolting on site. Every element was modelled in 3D, allowing coordination between steelwork, precast panels, deck reinforcement and shear studs.

The Narellan Rd Upgrade (Bridge No 2) was awarded a High Commendation in the Engineering Projects category.

These winners will go on to vie for national honours in their respective categories, to be announced at the Steel Excellence Awards ceremony in December.
