Other key achievements include:

Grange management were heavily involved in supporting the Delta site team and in producing a meticulously planned and integrated works programme – designed to successfully complete all works on time, on budget and without incident, involving a series of unique civil construction. Construction of a containment cell in 300mm layers – down to 4m – to achieve the required compaction for pile mat and slabs. Due to contaminated soil, the containment cell was built up and covered in orange geofrabric. This process was repeated with clean fill to ensure compaction over the entire surface area. Sequence changes to accommodate the archaeological study allowed the installation of piles to commence as per the agreed works programme. This also led to the management of up to five multiple workfronts. Bulk excavation of 88,000 cubic metres -48,000 cubic metres of contaminated spoil plus 40,000 cubic metres of cleanfill. 25,000 sqm of pile mat – comprising 300mm sandstone and 100mm crushed concrete. 9,000 cubic metres of crane mat – comprising 500mm sandstone and 500mm crushed concrete. 700 trimmed piles. Detailed excavation of 9,000 cubic metres. FRP of 130 footings and 4 lift core bases.
