Research Value Management Workshops
Value Management Workshops:
Development of the R&D Programme:
• New proposals received (Oct 04)
• Bids collated and evaluated
• Proposed projects prioritised
• Programme matched to available resources
• Draft programme to HA Board (Jan 05)
• Submission to the Minister (Feb 04)
• Approval by the Minister (April 05)
Value Management Workshops:
HA Research Themes:
• Accessibility
• Asset Use
• Driver information
• Improved safety
• Integration
• Reducing congestion
• Sustainability
Value Management Workshops:
The Essential Criteria:
• Benefits must be clearly identified
• Proposals must be feasible/achievable
• Proposals in line with HA objectives
Value Management Workshops:
Criteria used for 2005/06:• Improving safety
• Reducing congestion
• Reducing environmental impact
• Enhancing driver information
• Optimising WLC
• More effective technical governance
• Speeding up delivery
• Developing Traffic Operator role
• Wider benefits
Value Management Workshops:
Scoring:
• Benefits
Score of 0 – None benefits
Score of 10 – Exceptional benefits
• Likelihood – Score (0 - 10)
Research Value Management Workshops
Proposed Research Projects for 2005/06
Proposed New Projects 2005/06
• Early application of waterproofing systems to bridge decks
• Impact of revised HSE Standards on tunnels
• Assessment rule s for web stiffeners in steel bridges
• Half- joint bridge testing
• Temperature effects on integral bridges
• Design and strengthening of bridges for vehicle impact (desk study)
• Assessing defect acceptance in FRP materials
• Steel fibre-reinforced concrete – Concrete Society Report
