New Bauer rig in use to case piles in unstable ground near surface.
Piling work for a new car park at the Scottish Exhibition and Conference Centre (SECC) in Glasgow is progressing well despite challenging weather and difficult ground conditions, reports piling specialist Bachy Soletanche.
Bachy is working for design and build contractor SCC on the £750,000 project and the seven-week programme of work is well underway.
The new multi-storey car park is located over a former dock that was backfilled in the 1950s, so there is high potential for obstructions. Bachy used a CM120 piling rig to probe the area to determine the suitability for carrying out continuous flight auger piling.
Unstable surface layer
The survey showed that the top few metres were too unstable for CFA so Bachy is using a Bauer BG28/36 rig to case the piles through the first 10m.
The CFA piles within the dock were installed with 880mm of Bauer casing along with a 750mm diameter CFA auger, to a maximum depth of 23m to socket into the underlying sandstone. The piles outside the dock are 600mm and 750mm diameter CFA piles.
Extreme wet weather has also been a challenge on the project but Bachy Soletanche contract manager Chris Wallbank is confident the work will be completed on time.
The next stage of work on the Glasgow site will involve piling for a link bridge between the car park and the arena.
