Teeside debut for new Groundforce system

Groundforce Shorco’s latest brace support system has been put through its paces on the construction of a concrete fuel bunker for an energy from waste facility being built by Clugston Construction in Redcar, Teeside.

The new Super Mega Brace support system being used features integral hydraulic rams that have proved vital for the Redcar project to provide strong and rigid temporary support for the 13m deep, 50m long and 20m bunker.

The bracing provided support as Clugston excavated the bunker to expose the contiguous bored piles installed by PJ Edwards to a design by Byrne Looby. “Until you’ve cast the reinforced concrete base slab, there’s a risk of the bottom of the piles ‘kicking in’ under the pressure of the ground behind them,” said Clugston chief engineer Ray Postolowsky.

To prevent this Groundforce provided temporary propping at the base of the excavation and another level of support higher up to satisfy the high deflection and stiffness requirements calculated by Clugston’s consulting engineer Tata Steel Projects.

The MP500 and MP250 props were fitted with Groundforce’s real-time load monitoring system to constantly record the lateral forces.

“With this system, we know if there are any changes in pressure which would give us warning of any likelihood of movement,” said Postolowsky. “It takes all the guesswork out of it”.
