    A47 Roundabout Widening


    A47 Roundabout Project Overview

    The scheme comprised the realignment of the existing A47 roundabout on an arterial route through Cambridgeshire. This included the construction of an embankment on very soft ground. The scheme was part of a wider regional improvement to the road network.

    Scope of Works

    Our original scope was to undertake a ground investigation at the A47 roundabout. This comprised cable percussive boreholes with rotary coring follow-on and a series of dynamic cone penetrometer testing. However, using our experience in the area we worked collaboratively with the Client’s Designer to optimise the scope of works. We adopted cone penetration testing to characterise the very soft ground. We were also able to omit the need for rotary coring.

    Value Added

    We were able to utilise our past experience of working within the Fens to advise the Client on appropriate investigation techniques and ultimately deliver a saving of over £30k on the GI costs.
