THE BARRICADES came down last Friday on the new 2,500 sq.m covered car park situated between Emu Street and Crow Lane, after 24 weeks of construction. When it does rain in Longreach in the future, the roofline will harvest a vast amount of rainwater.

Bearing a striking design of huge wheels carrying the central roofline, the new 40 m x 60 m area has 73 car parks, four motor cycle areas, plus access for two mothers/prams and two disabled parks. The area is fully sealed in asphalt and cost $1.76 million to build.

Erected by Spantech, a family company based on the Gold Coast, this is the fourth project using this particular design.

Director Rick Lucas said each section of roof was 55.4 metres long, and roll-formed on site from five tonne coils of 1 mm sheet metal. Holes are punched into the metal where necessary as part of the process.

The company has three roofing profiles: the 300 series can have a 30-metre span as an arch or seven metre flat roof in 1 mm flat steel. The larger 370 series uses 1.2 mm metal and can have a 40-metre arch or 9-metre flat roof.

Referring to the Longreach design, Mr Lucas said this is a straight panel that can span 20 metres. “This one is 18 metres, and can also be in a curved design.

Across the entire length the roof has a one degree slope and a 900 mm fall.

Mr Lucas said the car park is floodlit and operates on an automatic trip. It can be used for markets.

“We are presently considering whether we market this design as ‘The Longreach’,” he said.
