In excess of £600,000 benefits identified at Contract Formation – Gateway 3.
13% saving on construction programme (7 weeks) achieved through design review.
£233/sqm savings through standardisation and alternative specification.
Transfer of knowledge from Tranche 1(a previous phase of the programme), significantly assisted the collaborative 2 stage open book procurement to improve on the procedures and processes.
Collaborative Engagement prior to Planning Application.
Early Engagement with Designers, Sub Contractors and Product supply Chain.
How these were delivered
Having created a Cluster Delivery Team (CDT) with the other contractors on Tranche 1, we were able to utilise the knowledge gained from taking the lead. Design management strategy was to integrate with the client design teams at the earliest opportunity, to identify key stakeholder requirements and maximise opportunity for standardisation and value engineering through our supply chain engagement.
Meetings with Miller consultants, client and Planning Authority led to alternative positioning and design of building, to secure a timely planning consent whilst also achieving significant cost savings.
Value engineering sessions with designers and subcontractor led to alternative substructure and ground floor solution to address nature of ground conditions, and simplification of roof levels and Parapet design.
“Total score of 43 out of 50 – An exceptional example of best practice with regard to the Considerate Constructors Scheme code of practice.”
Supply Chain Benefits – Early engagement of the supply chain has positively influenced outcomes, maximising overall efficiencies for cost, time and quality delivery. Miller Construction has utilised the early activities of the CDT to improve supply chain and cashable efficiencies.
Collaborative Engagement prior to Planning Application – A collaborative process takes time, but through engagement prior to RIBA Stage D, we secured a time saving in the planning application decision making process by approx 4 weeks (there is a statutory period of 8 weeks for the planning application). Miller Construction worked with our design team, Capita, to take the scheme back an RIBA workstage to Stage B in order to address buildability issues and produce a more cost effective building
Our Employment and Skill plan enabled employment training, apprentices and community engagement across a programme of works, providing continuity of employment across several projects.
A collaborative team with long term relationships across a programme of works also helps with many other wider objectives.
