Cadnet was appointed by Warings Contractors to provide an MEP modelling resource and MEP coordination role for the £45 million redevelopment and upgrade of Bournemouth International airport in 2008. This included the redevelopment of the existing arrivals terminal and up grading the check-in and departure lounges.
Starting with single discipline architectural and structural models, Cadnet federated the detail using Navisworks, converting the structural models from Tekla to a Revit compatible format. Cadnet then modelled the MEP services from design drawings and hand drawn sketches provided by the MEP consultants.
In just three months, Cadnet produced a fully coordinated MEP model together with a full set of 2D installation drawings produced directly from the 3D data.
The 3D model and clash detection process reduced the number of clashes requiring resolution on site and abortive works to just 1% of the scope, despite variations exceeding 30% during the duration of the programme. When scope creep occurs, abortive works are known to rise significantly. The exceptionally low level of abortive works on this project was as a direct result of the ability to test the impact of change within a 3D virtual environment and communicate the solution in a clear and concise manner.
Using the 3D model improved collaboration and communication between the design team and stakeholders and the availability of accurate project records has led to improved efficiency on all future design projects at the airport.
What the client said...
“Cadnet was responsible for developing the scheme design into fully coordinated installation drawings. Their role commenced with the onset of the M&E works packages working within a 12 week period to procure and install the multi-million pound scope.
The overall scope of the M&E works was varied by over 30% within the 12 weeks. The project team in most instances were able to visually see both the impact and aesthetic affect before the works were installed. The result was that the clashes and abortive works were limited to less than 1% of the scope of works. Even so we used less than 30% of BIM’s functionality.”
