• The previous planning process prompted a review due to the planning mandate of earlier work;
• SHI wanted an independent review of the previous study recommendations;
• The project had competing needs for access to Regina and to adjacent the Rural Municipality;
• MMM offered SHI a VE process in lieu of the Peer Review process
• Process also engaged the firm responsible for the planning to provide input at the Information Phase.

• Implementation is the responsibility of the design team• Project costs were validated and up to $5m in possible
savings was identified (for a project contingency cushion)• The VE challenged some of the project Design Criteria

Planning ProcessPasqua St & 9th Ave N/Ring Road, Regina
• Evaluate Options for an interchange for improved Traffic Operations, Safety, Construction Phasing
• Base Case was the interchange design from the previous study
• Evaluated at-grade options for an improved intersection at Pasqua and Ring Road to defer the construction of the interchange.
• Study also addressed the traffic delays at the intersections in the Pasqua Corridor from Sherwood to Rochdale
• Review opportunities to improve the safety and traffic operations.

Planning ProcessPasqua St & 9th Ave N/Ring Road, Regina
• 121 Ideas were generated with 31 Proposals– Diverging diamond interchange– XDL Intersection– Rotary interchange
• Addressed Value Target considerations– Corridor and cross section options– Interchange layouts versus intersections– Up to a $19.2M savings on $23.7M
• The preferred solution best accommodates the traffic flow patterns
• Regina is considering pursuit of first XDL intersection in Canada

• Primary goal:Develop an ultimate functional plan for the Hwy 1
corridor in the City of Moose Jaw, SK
• Objectives:Validate interchange locations and medium to long-
term plans for the Hwy 1 corridor
Review existing infrastructure and develop ultimate Hwy 1 corridor short and long-term solutions to meet safety and traffic operation requirements
Determine value-base staged implementation of site-specific and corridor improvements

Corridor ManagementHighway 1 VA Study, Moose Jaw, SHI
• 187 Ideas, 35 Proposals, 50 Design Suggestions• Addressed two new interchanges
– Simple cost effective IC access solutions provided– Significantly reduced cost of proposals
• Improvements to existing interchanges– Upgrade to main IC into Moose Jaw– Geometric improvements to Manitoba Ave IC
• 4 Scenarios developed• Entire corridor improved and access managed for
initial proposed cost of the two interchanges• No savings but entire corridor addressed in terms of
corridor management: 2 for 1 deal

Project ValidationHighway 1 and 16 VE Study, MIT
• MIT did a year long preliminary design and cost review to reassess scope and manage cost
• The review cut project costs from $125M to $85.2M, which became the VE study Base Case
• The VE Study addressed the two interchanges• 3 Scenarios were developed• The VE session found $5.3M savings, a 6% savings, even after
the scope management exercise• The Province was impressed with process/results• VE showed potential to replace the planning effort with a VE
process to cut cost/save time in making a decision

Summary• VE is a flexible tool that serves many needs• Effective in Alternative Delivery to deliver innovation• Offers an alternative means of Peer Review• Can provide a second review to assist with Cost
Management• Offers opportunity for creativity and idea generation
in the Planning Process• Serves a role to provide analysis and test options in
corridor management studies• Can validate project costs and serves to confirm cost
savings• VE/VA has a role in almost any project
