The development of the Brent Cross Site in North London, with scope of work developing from Construction Logistics and GRIP Stage 3 approval to Network Rail.

The MML Link Bridge comprises a £45m, 100m span dual carriageway road bridge, above the critical Midland Main Line rail tracks in North West London. The services provided by Design ID included reviewing wider site context to enable the feasibility design, before considering the structural design options of an arch bridge, a balanced cantilevered bridge or a truss span. Network Rail liaison and approvals were undertaken following this work, working closely with the design team.

Design ID were commissioned in March 2016 to undertake a construction feasibility and design study, discussing possible options for construction and ensuring their design feasibility within budget. The options presented ensured the feasibility of construction of the bridge above the rails during a 3 day track possession.

Challenges also included transport to site logistics, cost and programme issues, fabrication of thick weathering steel plate structural members, site tolerances for connecting components, procurement of materials, site access generally around constraints, and working within the space available on site. Design ID developed a site model and detailed construction sequence to show the challenges clearly. The study also identified opportunities for structural design changes at an early stage which would reduce construction risk.

The commission also included producing architectural images of the scheme to help demonstrate the architectural context of the bridge proposal in the wider site, to allow Client Approval of concept design.
