Our Latest Temporary Works Projects

Dunkeld, Scotland, UK

LSY Engineering Consultants Ltd was appointed as Temporary Works Engineer and Contractor's Engineering Manager (CEM) Coordinator for the upgrade and installation of an Intermediate Pressure (IP) Gas Pipeline adjacent to an operational Network Rail tunnel in Scotland. The works formed part of a critical infrastructure upgrade located along one of Scotland's principal rail corridors between Edinburgh and Inverness. Due to the operational requirements of the railway network, construction activities could only be undertaken during restricted overnight possession periods between 23:00 and 05:00. Our role included the design of temporary protective barrier systems to safeguard the railway infrastructure during the works, coordination of engineering approvals, and management of the temporary works process in accordance with Network Rail requirements.

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.

Vine Street, London, UK

LSY Engineering Consultants Ltd was appointed by Cadent Gas Ltd to undertake structural surveys and structural appraisal checks for an existing road bridge near Farringdon Station, London. The project formed part of a gas network upgrade programme and involved the installation of two new medium-pressure cast iron (CI MP) pipes beneath the existing bridge structure. The works included abandoning an existing 48-inch cast iron main and replacing it with a 36-inch pipe incorporating a 630mm polyethylene (PE) medium-pressure gas main. Our role included assessing the existing bridge structures, evaluating the impact of the proposed additional loads, and undertaking post-construction inspections to verify that the completed works had not adversely affected the structural integrity of the bridges.
