Ongoing Works
Steel Propping:- Large steel props are largely installed to the north and south of the site. These brace at ground level along the capping beam in order to restrain the ground pressure from the surrounding sides of the building while digging continues.
The Big Dig:- Excavation of the soil within the footprint of the building started ahead of programme and is expected to continue until Christmas 2011. There will be over 47,000m3 of soil to be removed. The gravel will be recycled and the clay used locally as fill material. As the excavation proceeds the props and capping beam will be closely monitored to ensure there is no movement.
Cleaning of Piles:- As piles continue to be exposed piles (concrete “wall” below ground level) they are being cleaned and inspected.
Future works for December
The Big Dig:- The excavation overall is now just over two thirds complete. The north is down to the correct level, the south will have another week for main dig excavation, and the central section will continue into the new year. The removal of soil will change from loading the lorries at the base of the ramps to loading from ground level as the excavation diminishes.
GSHP:- The pipes that were sunk at the start of the project will now be cropped and joined to header connection pipes that will terminate in access ducts in the plant rooms. The 1st section of the north is complete and the 2nd section of the north is due on Tuesday 6/12/2011. The south will then be progressed from Wednesday 7/12/2011.
Drainage & Slab:- By mid December the drainage will be ongoing and the 1st basement slab will be formed in the north of the site.
Hoarding:- Hoarding works adjacent to the main access road is continuing towards Gate 7 and is expected to be complete by 5/12/2011.
Tower Cranes:- Crane bases are concreted. The 1st tower crane is planned to be erected by use of a mobile crane on the weekend of 7th and 8th January 2012.
