The A1 Leeming to Barton is an exemplar project thats driving a culture change through BIM at it's best. The raft of clever techniques on the A1L2B are a result of the team's truly collaborative, open & a blame free culture.
This Carillion & Morgan Sindall joint venture, supported by designers Aecom and Sweco, has pioneered a culture change in the highways sector through an early engagement approach and by embracing digital innovation and collaboration in many ways. Here are just a couple of the highlights:
The use of BIM increased programme surety and measurable savings in excess of £3m, enabling programme to be optimised and shaving four weeks off the contract’s critical path. The team decided at an early stage to construct the project without the use of setting-out pins and to use digital machine control.
Additionally, the design team developed parametric milling templates allowing detailed planning and programming of the online road-widening works. This maximised the use of the existing asset by profile planning the existing carriageway, allowing the pavement layers to be milled to a level consistent with the adjacent widened carriageway.
