Sisk A19/A1058 Coast Road junction improvement

Highways England appointed the contracting joint venture companies Sisk and Lagan to construct the highly complex A19 and A1058 Coast Road junction improvement in North Tyneside, in the North East of England.

The project, which started in August 2016 and completed in April 2019, was extremely complex due to its size and scale. It involved working in a busy, constricted and live environment within a major infrastructure route through the region.

The construction methodology posed significant challenges to ensure the project could be delivered on time, on budget, safely and efficiently, while maintaining high levels of network availability and improving road user satisfaction with minimal disruption to transport routes.

The project team sought an innovative solution with the support of BIM Academy that would enable them to meet the project requirements while delivering a high-quality structure in a safe environment for all involved.

BIM Academy became part of the project team and collaborated to introduce innovative BIM processes. We focused specifically on the benefits offered by 4D tools to aid planning coordination, buildability and temporary works design, to significantly reduce the risk on the project and optimise the proposed solution.

We reviewed and assessed the potential construction sequences in a virtual environment prior to starting on site. We used 4D BIM to make it possible to visualise how construction sequencing would work at any point in time, by creating a visual dynamic sequence derived from linking 3D design models to planning software.

This enabled the planners to visually communicate and plan activities in the context of time and space, taking account of resources, procurement, spatial constraints and other concerns. This allowed the assessment of alternative approaches to site layout, scheduling and logistics during the construction phase.

This optioneering process allowed the contractor to assess all risks and opportunities and give valuable feedback regarding constructability, estimated construction cost and sequencing.

The A19 and A1058 Coast Road junction project is one of the first major highways infrastructure projects in the UK to utilise 4D BIM. This approach led to the project being completed 31 weeks ahead of schedule.
