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
