Asda Sunderland, was an existing store build in the 90’s with a sales area of approx 38,000 sqft. The works required to introduce a further 20,000 sqft of sales without change to the planning constrained building footprint.
Numerous designs were developed with the conclusion that the introduction of a mezzanine sales floor was the only available option, accessed by stairs / lift / travelaters.
Not only did the cost of removing the existing 2m deep steel roof trusses whilst the store still traded challenge the project, but also the construction of a mezzanine floor without affecting shopping figures created a real focus for the team.
Project BIM model
An effective way of working within an existing store had to be exercised to ensure minimal errors occurred once on site. It was essential that the proposal fitted within the shell plan and height wise beneath the existing roof structure.
The scheme was developed in the BIM way of working, the existing building fully surveyed and modelled in 3d, proposals developed in the BIM world and all produced from the model data.
This provided value engineering, full co-ordination of all elements, clash detection, virtual build of the scheme, communicating to stakeholders for sign off, all leading to a build once with minimal errors when the project hit site.
The elements of the project produced in 3d data included architectural, structural, M&E – all working in a single co-ordinated model.
Working initially with our client Asda we developed the concept to a workable scheme, submitting and gaining planning approval.
On receipt of planning the project moved forward under a traditional contract between our client, Asda and their chosen contractor, ISG.
We developed the design from planning stage through to tender and construction all as lead consultant, utilising the benefits of BIM to collaborate between the team.
Our works continued in monitoring works on site and attending both design team meetings and client meetings. A continued update of the BIM data continued throughout the build with a handover of data at completion.
