BB Design Forum Discussion James Bourne Stephen Workman
Symptoms The critical symptoms of failure and poor performance have been identified in this review as:
• Low Productivity
• Low Predictability
• Structural Fragmentation
• Leadership Fragmentation
• Low Margins, Adversarial Pricing Models & Financial Fragility
• A Dysfunctional Training Funding & Delivery Model
• Workforce Size & Demographics
• Lack of Collaboration & Improvement Culture
• Lack of R&D & Investment in Innovation
• Poor Industry Image

‘Standardised design’
3. Kit of Parts and Complex Assemblies
1. Template
2. Volumetric and Hybrid
Why Standardise?
Historic Stigma - Modular
Quality – Increased through familiarity
Time – Reduced Site Delivery
Cost – Repetition and Volume reduce cost
Design - Efficiency & Flexibility
Technology – BIM Integration
Safety – Off Site greater control

Volumetric
Hybrid Volumetric
Kit of Parts & Complex Assemblies
Complex Assemblies
PSBP Yorkshire Schools Brief: Develop a ‘smart’ school design solution which will be based on a
predefined kit of parts which make up a fixed % of any school scheme and is
of a known fixed cost (capex, energy, lifecycle & FM) and programme.

Lessons Learnt
• Detailed Facilities Output Specification
• Well-integrated and simple buildings
that benefit from daylight and
natural/hybrid ventilation
• A fabric first approach, where the
building fabric is the primary means of
controlling the internal environment
that perform better than ones with
complex M&E systems and bolt-on
technological features
• Multi-disciplinary integrated approach
essential from day 1, particularly
environmental engineer and architect
working together but also early advice
on ICT and Acoustics
• It is important to get the design right
at an early stage
• Providing daylight into circulation
areas and rear of classrooms
• Achieving GIFA - matching the
Schedule of Accommodation is a
challenge
• Efficiency of circulation is a big
challenge as are limitations on
space for servers and plant
• Is the indoor environment, daylight,
lighting, heating and ventilation
easily controllable locally by the
building users
• FM and environmental design
• Very few derogations, or better No
derogations
Lessons Learnt
• Standardised approaches to plant and
services, eg strategy for routing services,
risers, service cores, etc
• Standardised solutions for façade, ventilation
and lighting solutions
• However too much standardisation can
severely compromise quality so a portfolio of
solutions may work best. Flexibility of material
and forms.
• Can offsite manufacturing speed up delivery
and improve quality?
• Windows and louvers
• Plant and services
• Metering and monitoring
• Local control strategy
• FM and asset renewal strategies
• Shading devices
• Opening mechanisms
• Floor to ceiling heights
• Door panels and glazing to corridor
• Servicing of teachers wall
