East Midlands Modular Project Final Peer Review for Constructing Excellence James Rix Construction Team Manager – South PfP Developments Ltd
Why this route? • 4 Sites in the Midlands • Tender Prices • NBH owned the sites • Using NBH standard house types • Needed to progress quickly • Pilot scheme needed
PROPOSED BENEFITS Construction Time • On-site period – 50% No increase in period for design development • Utilities connections on critical path
PROPOSED BENEFITS Predictability • Significantly Increased + 50% • Reduction in trade interfaces • Factory culture
PROPOSED BENEFITS Defects - Aims • Significantly reduced – 50% • Quality built in, not inspected out • Increased Automation • Minimal Tolerances
PROPOSED BENEFITS Productivity • Significantly increased • Less reliance on weather • Increased Automation • Deskilling of Process
PROPOSED BENEFITS Turnover and Profits • Opportunity to double output using the same level of resource • Opportunity to increase profit due to limitation of risk
BENEFITS Capital Cost • Need not be more expensive • Varies from Region to Region • Dependent upon Volume • Superstructure more expensive + 30% • Savings in: Substructure - 25% Preliminaries - 50% Design Fees - 50% Overheads - 30%
Fact Sheet • 4 separate sites • Total Contract Sum £905,000 • Cost per m2 £947 • Cost per dwelling £56,500 • Construction period 34 weeks • Form of contract JCT ’98 WCD
Key Performance Indicator's • Time – 55% saving • Cost – Accurate predictability • Quality – Defects 5% higher at handover • Man hours – 36% fewer / £100k
East Midlands Modular Project – Lessons Learned • Time of year influential / weather protection • Early involvement of Regulatory Bodies/ Funders • Coordination of Public Utilities • Access and logistics requirements fully appraised • Completion within factory • Valuations/Communications
Lesson’s Learned • All design development must be 100% complete before the units go into production in the factory.
BENEFITS Defects • Quality built in, not inspected out • Increased Automation • Minimal Tolerances
