London Gateway - BOXBAY Main Works

Tender description

The BOXBAY Works at the existing MT Park area of London Gateway comprise the demolition of existing below-ground services and the construction of the substructure, superstructure and associated infrastructure required to deliver the BOXBAY automated high-bay empty container storage facility. The works will be undertaken within the constraints of an operational port terminal. The proposed structure will have approximate plan dimensions of 323 m in length and 159 m in width and will rise to approximately 55 m above ground level. The substructure works include the removal of existing underground services and the construction of the below-ground structural, civil and services infrastructure required to form the foundation platform for BOXBAY. The works include the installation of in excess of 5,000 precast piles, nominally 28 m in length, to support an approximately 1.2 m deep reinforced concrete raft foundation. The scope also includes the installation of below-ground services infrastructure, including stormwater drainage systems, electrical service infrastructure, earthing systems, potable water supply and firewater networks. External civil works form part of the project and include the construction of heavy-duty pavements, kerbs and the installation of associated road furniture. Minor building works are also included, comprising the construction of a single-storey masonry office/store building and two concrete-framed, double-storey e-house/transformer buildings. The principal superstructure works include the fabrication, supply and erection of in excess of 15,000 tonnes of structural steelwork, together with approximately 50,000 m² of external side cladding and a siphonic roof drainage system for 46,500 m² of roof sheeting. The works also include the construction and installation of two lift cores, six external staircases and 3,0 km of rail for 15 storage retrieval machines (SRM). SRM's supplied by others. The scope further includes internal building services such as fire detection and fire prevention systems, ventilation, thermal insulation, power distribution, IT infrastructure, internal lighting and lightning protection systems.
