Scheme History

• Award of ECI Contract in March 2004 to Alfred MacAlpine/AMEC

• Bullen Consultants as Lead Designers with sub-consultants Carl Bro and RPS

• Public Consultation in June 2005

• Publication of draft Orders in March 2006

• Public Inquiry Oct 2006

• Secretary of State Decision Letter 31 March 2008

• Dishforth to Leeming commences construction March 2009

• Two schemes developed in early 1990’s

• Public Inquiry held on Leeming Bar to Scotch Corner in 1995

• Orders published but not made on Dishforth to Leeming Bar

• Both schemes withdrawn from Roads Programme in 1996

• Upgrade added to TPI 2002 after a Safety Study

• Preferred route announced in July 2002

Dishforth to Leeming Leeming to Barton

• Award of ECI Contract in March 2004 to Carillion/Morgan Sindall

• AECOM as Lead Designers with sub-consultants Grontmij and RPS

• Public Consultation in June 2005

• Publication of draft Orders in March 2006

• Public Inquiry Oct 2006

• Secretary of State Decision Letter 31 March 2008

• Dishforth to Leeming commences construction March 2009

Promotion of Ideas • How

- working collaboratively

- value management reviews involving:

ECI Team

+ HA Specialists

+ Key Stakeholders

- Ethos developed within team

- Knowledge Transfer from previous M6 ECI team

Case Study 1: Risk Analysis

• Collaborative approach

• Risk Manager

• Output

Collaborative Approach

Team evaluation

Monthly review by key team (HA, Employers Agent, Contractor and Designer

Periodic involvement of Key Stakeholders

Risk Manager Same Person

Was able to bring forward issues currently being experienced

Provided a reality check on the issues being recorded

Output

Greater understanding of the risks leading to better management

Better understanding of stakeholder issues

Increased confidence in the valuation

Case Study 2: Interim Road Safety Review

• Collaborative approach

• Output

Collaborative Approach

Promoted by the design team as a method of raising confidence in the finished product

Facilitated a confidence level with the Client

Essential early involvement of Key Stakeholders

Output Right first time product allowing early opening for traffic – WS1 was 6 months early

Used in review process by Client through Employers Agent to provide confidence in the product

Submitted as part of design package to Local Highway Authority

Case Study 3: Use of gINT

• Identification of the issue

• Resolution of the Issue

• Output

Identification of the Issue

Over 50 years of data available from numerous sources (10 GI’s in the period)

How do you bring them all together and make the information available?

Resolution of the Issue Collate the information within gINT (an Excel based software package)

Software created a colour coded model for the strata layers

Output

Production of geotechnical sections

Output

Earthworks example

Output

Balancing Pond example

Output Structures example

Output - Summary Having over 50 years of ground investigation data in one place and readily accessible has proved invaluable. Visualization and analysis of legacy data at an early stage in the project aided and optimized the scheme specific ground investigation – enabled cost savings. Ability of gINT to produce geological sections in seconds has provided time and therefore cost benefits throughout the project from feasibility through to detailed design.

Case Study 4: IDC Process

• Collaborative approach

• Output

Case Study 4: IDC Process

• Collaborative approach

ECI team involved in IDC processes

IDC Manager + Construction Manager + Discipline Team Leaders

• Output

IDC identified conflicts early in design – reducing abortive costs

IDC adopted collaborative planning to assist sequencing detail design

IDC reduced conflicts during construction
