Our Structural Design Projects

Temporary Works

Brighton Theatre, Brighton, UK

LSY Engineering Consultants Ltd was appointed as lead Temporary Works Engineer for the restoration of Brighton Theatre, a historic venue located in the centre of Brighton. The project involved the replacement of an existing balcony structure and the formation of new structural openings within the building. Our scope included temporary works design, site supervision, structural engineering support, and BIM modelling to facilitate the safe delivery of the refurbishment works whilst preserving the theatre's historic fabric. The project required a carefully coordinated temporary works solution capable of supporting both the existing balcony and a 450mm thick masonry wall during construction, whilst maintaining access to the theatre and minimising disruption to the surrounding public realm.

Temporary Works

Weedon Street Bridge, Sheffield, UK

LSY Engineering Consultants Ltd was appointed by Cadent Gas Ltd, to provide structural engineering services for works associated with Weedon Street Bridge in Sheffield. The project involved the removal of two 24-inch gas mains attached to the east and west elevations of the existing bridge structure. Each pipeline extended approximately 70 metres across the River Don and required careful planning and execution due to the age of the bridge, the scale of the pipework, and the operational constraints of the site. Our appointment included: An initial structural condition survey and reporting. Structural assessment of the proposed temporary works and scaffold arrangements. A post-completion structural inspection to verify that the removal works had not adversely affected the bridge.
