Allen Watson Limited have completed a multipipe installation at the A340 Thornycroft Roundabout, Basingstoke.

In total AWL completed the installation of 240 metres in diameters DN225, DN300 and DN450.

The project required temporary off-peak traffic management, Monday to Friday between 9:30am to 4pm to reduce traffic flow to single file to facilitate these works with capacity being increased to two lanes in each direction at peak times with no road closures.

The ground was found to structured chalk with light brown marling, slightly gravelly slightly sandy silt. Gravels were subrounded to subangular fine to coarse of low-density chalk and flint above the water table with the s.p.t exceeding N=45. For this reason, AWL decide to deploy 2 No machines which reduced all unexpected changes in ground conditions.
