Crossrail Bond Street Station
LBA supports Costain/Skanska in key positions of Engineering Manager, Design Manager, LU Interface Manager and Instrumentation and Monitoring Manager within the project team. During the preconstruction ‘Optimised Contractor Involvement’ (OCI) phase, LBA advised on constructability and construction sequence and associated temporary works as well as the establishment of the required monitoring regime.

Project Description: The Bond Street Station project involved the design and build of a Crossrail station in the heart of Mayfair, London. The project consisted of the construction of two 35 metre deep station boxes (250 metres apart), using diaphragm walling and secant piling. This was followed by top-down methodology for the excavation and floor construction. The project also included the complete design and installation of all M&E equipment, architectural finishings, lifts and escalators, and integration with the existing London Underground station and Crossrail’s Systemwide contracts through the connecting tunnels.
Within the project team, LBA supported Costain/Skanska in key positions of Engineering Manager, Design Manager, LU Interface Manager and Instrumentation and Monitoring Manager. During the preconstruction ‘Optimised Contractor Involvement’ (OCI) phase, LBA advised on constructability and construction sequence and associated temporary works as well as the establishment of the required monitoring regime. During the design development and construction of the heavy civil works LBA provided:
Engineering and Design Management
• Temporary Works Coordinator for the project
• Leading design management team delivering the MEP, Architectural, Structural and Urban Realm Stage F design for the station including assurance thereof.
• Responsibility for the works being installed in accordance with the design information and to quality requirements
• Engineering expertise and knowledge to deliver the design and installation works with efficient solutions to engineering problems and to quality requirements
• Working with the construction team, supply chain, Client and Designer to deliver value engineering solutions
• Engineering leadership for the project team with regard to permanent and temporary works design, settlement monitoring, quality regimes and assurance
• Establishment and Management of the Monitoring regime.
• Expert advice on the interpretation of raw instrument data from the complex geotechnical instruments providing assurance of the design.
• Value Engineering Proposals for the Monitoring regime during the top down construction of the two ticket halls.
LU Interface Management
• Interface Management with London Underground for design interface to ensure the new station is fully coordinated and integrated with the existing LU Station.
• Interface Management with London Underground for construction interface.
• Interface Management with London Underground for assurance and acceptance of the Contractor’s design.
• Implementation of Value Engineering proposals to construct the Masterplan Shaft “bottom-up” as opposed to “top-down”. This resulted in programme benefit, reduction of temporary works requirements and safer construction methodology
• Extensive knowledge of instrumentation and monitoring provided clarity in the interpretation of results, offering confidence to the project team and Client
• Knowledge of Design Assurance process provided the project with a new process to manage design change more efficiently and release design information for construction in line with programme requirements.
