ITM – The go-to company for DLR monitoring

ITM Monitoring are pleased to be working with Telford Homes and Docklands Light Railway (DLR) during the build of the recently announced Calders Wharf mixed-use housing scheme in the London Borough of Tower Hamlets. The site is overlooking the River Thames and the Greenwich World Heritage site.

The development of 25 homes and a new community centre includes the demolition of the previous community centre from the 1970s. The new housing is designed by architecture practice Stockwool.

The DLR tunnels located directly beneath site, which pass under the Thames to Greenwich, had to be taken into account when considering construction techniques for this four-storey scheme.

DLR were concerned that no material load was to be imposed on the tunnel and that the developer, Telford Homes, assures the security of the underground structures throughout the works. It all became possible with the experienced consultation and assistance of ITM Monitoring, who will provide the design and installation of the rigorous monitoring of the north and southbound tunnels.

Working to DLR’s tight specifications the monitoring scheme has been installed between the Cutty Sark and Island Gardens DLR Stations, totaling approximately 90meters.

All ITM site personnel have DLR Track Certification and are familiar with working in tunnels from previous projects including several Crossrail projects, the Victoria Station Upgrade and now the K1 development in Knightsbridge on the London Underground.

Project Manager Simon Hough comments

Staff have been on site since spring and we are working from a control room at platform level to monitor the information from our four Robotic Total Stations (RTS) which work with the twenty 3D prisms installed in the tunnels. Two data loggers will be transferring information on an hourly basis back to ITM’s head office.

Dave Farnham, ITM’s Technical manager adds

The data will be analysed our proprietary software Calyx OMS™, on a twenty-four hourly basis, giving monitoring reassurance to the DLR.

ITM are proud to be working on this project designed by one of the top 50 architectural practices in the country and winner of the Architectural Journal’s Fastest Growing Practice 2017 award, Stockwool, and Telford Homes, the fastest growing build to-rent developer in the UK.
