Excavation as appropriate; Installation of blinding (concrete); Construction and installation of timber formwork and supports; Installation of steel cages for structural support (rebar); Placement of structural concrete around rebar; and Curing of concrete and finishing.
457. It should be noted that prior to undertaking detailed ground investigations, it is not yet possible to determine whether piling is required in order to support the foundations and limit settlement to acceptable levels.
5.6.10.8 Construction: Buildings 458. The proposed building substructures are typically predominantly composed of steel and cladding materials. The structural steelwork would be fabricated and prepared off site and delivered to site for erection activities. The steelwork would be erected with the use of cranes.
459. Cladding panels (typically composite) would also be delivered to site ready to erect and be fixed to the steelwork. A variety of means would be used to install the cladding, depending on the particular area being accessed. The control building would include the construction of brick or blockwork partitions and would include a number of follow on trades for plumbing, plastering, and low voltage mechanical and electrical installations.
5.6.10.9 Construction: Installation Works 460. For the installation and commissioning phases of the project a variety of specialist activities would be required. The main aspect of installation within the building would be the valves themselves. These are typically installed with the use of specifically designed beams that are part of the structural fabric of the building.
461. Another main part of the installation would be the transformers. These items of plant would be delivered sealed and would be particularly bulky, heavy items. Due to their size and weight they would be delivered via specialist means and offloaded with the use of a mobile gantry crane.
462. The majority of the remaining HVDC equipment, HVAC equipment and cooling towers would be erected with the use of small mobile plant and lifting apparatus.
