Our Latest Temporary Works Projects

Sirinham Point, London, UK

LSY Engineering Consultants Ltd was appointed as lead Structural Engineer for a complex remediation project within an occupied eighteen-storey residential building. The project involved assessing the feasibility of removing an existing reinforced concrete shear wall at basement level to create access for the removal of contaminated water and oil storage tanks. Our involvement spanned the project lifecycle from initial feasibility and site investigations through to concept development, detailed design, and tender-stage support.

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.
