Gate Complex, DP London Gateway Port

Construction of the main entrance to the London Gateway project - the UK's newest deep-sea container port

Project outline 

The Gate Complex project is on the site of the London Gateway project – a new deep-sea container port, also incorporating Europe’s largest logistics park.  The port is being constructed progressively over approximately ten years, and the Gate Complex forms the main route through the new port to the completed Berths 1 and 2, which are already operational.

The brief included the design and build of the main entrance canopy into the site and associated operational buildings, plus development of the surrounding area including:  provision of over 300,00m of ducting networks on site, construction of 130,000m sq of heavy duty port pavement dressed with machine laid interlocking block paving; extensive deep drainage, and a segmental shaft pumping station capable of dealing with 3,000 litres of water per second. 

Key challenges

During this fast track programme over 200 resources had to be managed on site over multiple activities.  High quality standards were set by the Port and Heavy Duty Pavement Design Manual and bulk volumes of materials were needed, including the importation of over 300,000 tonnes of materials to site. 

Project delivery and innovation

Working with the Client’s team we developed a number of innovative solutions to improve efficiency and minimise the environmental impact:

Excavation of 300,000m3 of earthworks was retained on site.  Contaminated material was treated on site at a ‘soil hospital’ to allow for use in the works and avoid the need for waste disposal. 

Over 1,800m of 12m long precast box drain units were prefabricated and installed on site using a bespoke method of stitching we developed with our partners.

An extruded, slip-form method of construction was used to form vertical 1m deep concrete walls – this allowed over 200m to be installed within a single day, using a specially designed concrete mix.

The design specified 150,0000 tonnes of sub base type 1.  To reduce the environmental impact of quarrying such a large volume, Murphy developed a 50/50 blend of granite and recycled incinerated bottom ash with Sterna Shipping.  This product was approved by the Environment Agency, which cited it as an example of best practice. 

Throughout the project, a number of additional works were added by the client and our team worked closely with the fitting-out contractors, operational team, DP World and the engineers Cullen Grummitt and Roe (UK) Ltd.
