Refurbishment of Main Train Shed Roof for Network Rail

Robinson Kenning & Gallagher produced a Listed Building Application with WYG on behalf of Network Rail for works relating to the refurbishment of the main train shed at Kings Cross Station, London. The Client brief required a detailed survey of the main train shed roof (primarily two large barrel vaults separated by a brick central spine wall) including, detailed structural assessments and inspection, and a condition survey of both the interior and exterior fabric to the roof coverings.

Over a ten-month timescale, regular meetings were held with Camden Conservation Planners and English Heritage representatives, in order to relate the results of the structural investigations and to develop an acceptable proposed design for the refurbishment of the main train shed. A presentation was made to Camden Conservation Planners and English Heritage identifying alternative design options for addressing structural concerns. Amongst other criteria, the presentation was based on wind tunnel test results, impact of snow (and snow drifts) calculations and recommendations for improving performance of the bow string purlins.
