A30 Bridge, London, UK

LSY Engineering Consultants Ltd was appointed by Cadent Gas Ltd to undertake structural engineering services associated with the upgrading of gas infrastructure located within an existing road bridge on the A30, London. The project involved the inspection and assessment of existing gas chambers, valves, and associated pipework located within and beneath the bridge structure. In addition, new gas pipe connections required the construction of access shafts ranging from 3.5m to 4.2m deep, necessitating careful consideration of excavation support and temporary works requirements. Our scope included structural surveys, condition assessments, temporary works evaluations, and recommendations to support the safe delivery of the proposed gas infrastructure improvements.

Balfour Place, London, UK

LSY Engineering Consultants was appointed to provide temporary works design services for the structural refurbishment of a six-storey listed property with basement accommodation in Mayfair, London. The project involved the removal of several loadbearing structural walls at basement level and the formation of new openings through existing vault structures as part of the wider redevelopment works. LSY's commission was to develop temporary works solutions that would safely support the existing structure during the demolition and alteration phases. Our scope included the design of needling and propping systems to facilitate the removal of basement walls, together with roof support and back-propping arrangements to maintain structural stability throughout the top-down demolition sequence. Challenges The project presented several significant engineering challenges. The property was a listed building located within a sensitive Central London environment, where historic bomb damage from the Second World War had the potential to affect existing ground conditions and foundation arrangements. As a result, excavation works required careful planning and execution to minimise risk. In addition, the existing foundation details at basement level were unknown. This uncertainty necessitated a programme of trial hole investigations to establish the form and condition of the foundations before both temporary and permanent works designs could be finalised. The constrained nature of the site, combined with the requirement to maintain structural stability throughout the demolition process, demanded a highly coordinated temporary works strategy.

Charing Cross Station, London, UK

LSY Engineering Consultants Ltd was appointed to provide temporary works design and structural engineering support as part of a £20 million programme of upgrades to the 175-year-old Hungerford Bridge at Charing Cross Station. The project involved the replacement of approximately 2km of country-end platforms with new Glass Reinforced Polymer (GRP) platforms supported on a new framing system incorporating elements of the existing structure. To facilitate the platform replacement works, two self-erecting tower cranes were required to undertake the dismantling and installation operations during a major engineering blockade. LSY's involvement focused on the construction phase, where we developed temporary works solutions to support the contractor's methodology and sequence of works. Our scope included the design of crane base foundations, assessment of structural risks, BIM coordination, and the development of temporary works solutions to protect surrounding infrastructure throughout the construction process.
