Description Energy from waste plant, Suffolk
Challenge Design and supply suitable solution to build a concrete bunker

Safety, speed and flexibility are among the key reasons why a lightweight aluminium shoring system from Hünnebeck (Formerly Harsco Infrastructure) has been chosen for a new energy from waste plan in Suffolk.

The Hünnebeck GASS shoring system will be used to construct the waste bunker that will lie at the centre of the new facility, in Great Blakenham, near Ipswich. An 8m high lift will be created to support an intermediate slab, on top of which a 10m lift will be used to support the top slab. Each slab is 300m² in area and 300mm thick, supported on 1,200mm deep beams. In all the GASS system will be required to support 186m³ of concrete, weighing over 450 tonnes.

"The Gass provided us a safe and quick solution for forming the Reinforced Concrete Bunker Slabs because we were able to build the Gass tower’s laying horizontally on the ground and then lift into position. By removing the lower frame allowed us to run scissor lifts between the legs for placing of the decking eliminating the need to form working platform below the primary beams."

 Rob Smith, Cidon Technical Director

This speed of construction and its inherent flexibility also allows the GASS system to be easily adapted to suit different requirements as the work progresses.

Safety is always a key requirement for designs developed by Hünnebeck, and the company was able to use its considerable industry expertise to propose a bespoke solution which met all the project’s requirements, while also providing a safe, on site working environment.

Hünnebeck’s GASS system can be used for shoring and back-propping on a wide variety of different project types, including industrial structures, residential and commercial concrete frames, and civil engineering projects such as reservoirs or power plants. It offers an impressive 140 kN per leg high loading capacity and requires only three main component parts outer legs, inner legs and ledger frames. The GASS system enables large quantities of falsework to be assembled quickly and easily for large scale projects.

When it opens in late 2014, the new facility’s 269,000 tonnes per year of waste handling capacity will allow it to handle all of Suffolk’s residual household waste.
