A decision to use LYSAGHT W-DEK® structural steel decking has solved design and site challenges at a new logistics and distribution centre in Sydney's west. Walker Corporation has just completed the new 3,000 square metre office and warehouse complex at Greystanes for diversified technology group 3M Australia Pty Ltd.
Grant Roe, Director of Costin Roe Consulting Pty Ltd, said the challenges posed by the Greystanes site and the layout of the building complex prompted his company's suggestion of the decking solution.
"Truck access from the road to the sloping warehouse site and the need to provide six metres of clearance on the building's lower level would have given rise to a lot of additional cost and complexity if coventional formwork had been used to create the slab," he said. "We suggested to Walker Corporation that LYSAGHT W-DEK® could provide a cost effective solution for the steel framed building."
Developed specifically for Australian conditions by BlueScope Lysaght's world class research and development team, Lysaght Technology, LYSAGHT W-DEK® is a steel formwork system that has been designed to provide optimal efficiency, speed of construction, and economy.
. Steel formwork acts not only as formwork, but additional bottom reinforcement as well, so less reinforcement needs to be used in the concrete. It also requires less propping than traditional ply formwork, and there is no stripping, which reduces material handling on site, leading to faster installation and reduced cycle times.
"On the 3M Pty Ltd site the use of traditional plywood formwork for the slab would have been a major undertaking," Grant Roe said. "The time and cost involved in providing propping above the six metre clearance represented a significant impact on the whole project."
"We were aware of LYSAGHT W-DEK® and its spanning abilities, so we recommended it to Walker Corporation for this application. It provided a very straightforward construction solution for what would otherwise have been a costly and time consuming task with traditional technology. We were able to use clear spans of four metres."
Walker Corporation and Costin Roe Consulting Pty Ltd co-ordinated the supply and installation of the complete suspended flooring solution through Lysaght Design and Construction, a subsidiary of BlueScope Steel.
On the 3M Pty Ltd project, Lysaght Design and Construction supplied and installed the LYSAGHT W-DEK®, all reinforcing and accessories, including the two-stage pouring of a concrete slab necessary to achieve effective drainage in a carpark area. Intimate knowledge of the project, from it's inception prior to design, right through to construction project management, was a significant benefit to all parties on this project.
Constructed of high-tensile Australian steel, LYSAGHT W-DEK® spans distances up to 40 per cent more than traditional re-entrant systems. Its unique "w" shaped profile has been designed specifically for its spanning capability.
LYSAGHT W-DEK® is also a slightly wider cover than other steel formwork systems, at 700 mm wide. With less sheets to lay and fewer props to handle it creates labour time and money savings.
The design of LYSAGHT W-DEK® optimises the way in which it bonds with concrete, giving it composite strength tested to be nearly four times the capacity of similar products tested overseas.
