CONTEXT
Principally due to demographic factors, there is currently an acute national shortage of primary school places.
However, following recent Capital Spending Reviews, the availability of appropriate government funding to meet this demand is limited.
A solution to address this issue partly lies in improving the processes through which new schools are delivered in order to ensure that well designed, environmentally friendly facilities are delivered as efficiently as possible – with particular regards to Capital Cost.
This project focussed on bringing about such improvements by developing a novel approach to project delivery – one which harnesses the power of BIM as a vehicle for collaboration.

The project has tested the proposal that such an approach would support:
stakeholders, designers and supply chain partners in a creative free-thinking environment (i.e. Design Review Meetings); and
the project delivery team during the construction phase; and continuous improvement of the design by using operational data.
Our results show that this BIM-enabled approach provides additional support for collaborative evaluation of existing approaches, envisioning and agreeing radical approaches and innovations for adoption.
The Scape National Major Works Framework through which Sunesis projects can be delivered and the long-term relationship between design partners have proven equally important factors for collaboration.

250,000 primary school places needed by 2020
Schools budget protected but pot size the same
Cost of creating places £12bn, government's commitment £7.35bn
C2025 - 33% cost reduction, 50% reductions in time and GHG emissions
Need to build more school places at reduced
cost & faster

• A collaborative team willing to improve the product through sharing and by making suggestions
• Limited use of federated BIM & construction simulation from the model
• Time-lapse video of the construction phase preferred for visualisation
• Digital 2D drawings were used

Design Review Meeting Findings
4D Made sharing ideas easier
visualisation Encouraged participants to share ideas
Made communication more effective but did NOT facilitate collaboration in the first place
Did NOT make it easier to co-ordinate designs during the meeting Neutral on identifying programme reduction opportunities or potential conflicts
Facilitated a more effective sharing of ideas but did NOT help with real-time evaluation of the implications of suggested changes

“..when you bring the model up there, you are not trying to interpret it from a
2D drawing. It is the same as standing on site and looking at the detail and saying
‘can we do that better…”
“You do not have to explain something to somebody. You can point to it. You can say: ‘look this is what I am talking about’. It is much easier than saying:
‘you know the little bit under the eaves …’”

To date Sunesis has delivered: Over 8,500 new school places 100% on time 100% within budget 100% client satisfaction
The use of BIM has helped Sunesis projects be delivered faster for Plymouth City Council – without any compromise in quality:
• Knowle Primary - Keynes2 2FEN – 30 weeks in lieu of 36 weeks (-6 weeks)
• St Matthews - Dewey 3FE – 39 weeks in lieu of 45 weeks (-6 weeks)

• Development of EFA FOS-compliant Sunesis Keynes3, again using BIM as a design enabler
• Further development of BIM-led design review tools (Oculus Rift, etc.) – particularly in a cloud environment
• Use of the same for improved Client engagement/interaction, including BIM-enabled website.
• Closer integration with Sunesis supply chain members as part of a move towards BIM Level 3
• Strategic aim to deliver 10 Sunesis projects in 2016, and 16 in 2017 – all to BIM Level 2.
NEXT STEPS
COMIT Conference 2016
#Comit2016
www.comit.org.uk
• Robust evaluations of ‘real-life’ BIM implementation are
emerging.
• BIM and other means of nD visualisation as enablers rather
than collaboration tools in themselves
• Need to scope BIM implementation to determine projects that
would benefit from implementation
• A BIM implementation matrix: project type, scale, complexity,
procurement method, and the ease with which internal
processes can be incorporated
