Site Operations


August 2022 – March 2023

Project Summary

Causeway Geotech were appointed by McLaughlin & Harvey to carry out a marine ground investigation for the provision of geotechnical information to characterise ground conditions at the proposed quayside extension at the existing London Gateway development.

The construction of the new Berth 4 facilities required investigation of the superficial soils to progress the design parameters of the proposed sheet pile wall.

Siteworks were carried out under the supervision of Site Engineers from Causeway Geotech who liaised with the Client’s Representatives to ensure all aspects of the works were completed safely and as per the project requirements.

The overwater works were carried out on a 24 hour day basis; two dedicated site crews worked around the clock to ensure the tight project deadlines were met as the marine GI spread worked ahead of the piling operation.

The project management team worked closely with the Client to achieve the required HSQE standards set by the licencing authorities, the Port of London Authority (PLA) and the Marine Maritime Organisation (MMO) who issued the work permits.

This contract also required careful planning from inception through to delivery due to the high volume of river traffic along the Thames in the vicinity of the works areas. Through open, honest, and constructive communications between the project team and the PLA, a project navigation plan was developed to ensure safe passage for all river users was maintained throughout the works programme.

The project was completed within the Client’s required timeline and most importantly without any complaints from the other river users.
