Sisk Lagan JV win RICS BIM Award

The A19-A1058 Coast Road scheme won the award for ‘Best Use of BIM for Construction Sequencing’ at the RICS BIM awards, hosted on HMS Belfast in London.

Project Background

Highways England appointed the contracting joint venture Sisk Lagan JV to construct the A19 / A1058 Coast Road junction improvement at North Tyneside. The junction, used by thousands of people every day, is on the main route to and from the Tyne Tunnel and will mean that drivers travelling along the A19 will no longer have to queue at the roundabout to go straight on. The project started in August 2016 and is due to be completed in March 2019.

The proposed works include:

• Realigning the A19 under the existing A19 roundabout;

• Constructing slip roads to allow the A19 / A1058 Coast Road junction to provide access to the junction to and from the lowered A19;

• Constructing 3 No. new single span structures to allow the A1058 Coast Road and A19 roundabout to cross over the realigned A19;

• Widening of the Middle Engine Lane railway bridge to accommodate the A19 north-facing slip roads and

• The installation of new infrastructure and street furniture associated with the scheme works and retaining and enhancing facilities for cyclists, horse riders and pedestrians.


Critical to the success of the project; the existing A19 and A1058 must continue to operate 24/7 in an efficient and safe manner. To enable a continuous safe environment, traffic management is currently in place on both the A19 and A1058 (lanes have been narrowed with 30mph speed limits) and there will be a 30mph limit on the A1058 for the duration of the work. There will be some overnight carriageway closures.


Due to the complexity and scale of the project and working within a busy and live environment, the construction methodology posed significant challenges to ensure the project could be delivered on time, on budget, safely and efficiently, while maintain high levels of network availability and ultimately improving road user satisfaction.

The Project Team sought an innovative solution that would enable them to meet the project requirements while delivering a high-quality product in a safe environment for all involved.


One of the most exciting developments within the AEC industry in recent years is Building Information Modelling (BIM). BIM is the creation of 3D data rich virtual models to support the design, construction and operation of assets. In addition, to the 3D model, other dimensions can be included to assist the Project Team;

• 4D BIM is the time dimension, which can be added to the BIM to assist with scheduling, planning and logistics of the construction and

• 5D BIM is the cost dimension, which integrates cost with the BIM to forecast and track the project costs throughout the design and construction.

The Project Team collaborated to innovate and utilise BIM focusing specifically on the benefits offered by 4D BIM to aide with Planning Coordination, Buildability and Temporary Works planning to significantly reduce the risk on the scheme and optimise the proposed solution.
