VE Scan of Western Canada Projects – The Flexibility of VE for Decision Making

VE Scan of Western Canada Projects – The Flexibility of VE for Decision Making | October 2012

Outline - Flexibility of VE for Decision Making• Alternative Delivery P3

– SE Anthony Henday, Edmonton, PCL

• Peer Review– Highway 1 Lewvan Drive, Regina, SHI

• Cost Management– Johnson Street Bridge, Victoria BC

• Planning Process– Pasqua & 9th Ave N/Ring Road, Regina

• Corridor Management– Highway 1 VA Study, Moose Jaw, SHI

• Project Validation– Highway 1 and 16 VE Study, MIT


Alternative Delivery P3SE Anthony Henday, Edmonton – PCL • VE Undertaken During Pursuit

– Materials supply and quality;– Structure span options and abutment configurations;– Retaining wall design, wick drain & maintenance considerations;– Interchange design departures from AT practises.

• Project delivery offered significant innovation thru VE– 91 street interchange layout;– High Level Structure;– High Skew Bridge;– Haunched Rail Structures;– Wetland Development.

Peer ReviewHighway 1 Lewvan Drive, Regina, SHI


• 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.



• The study resulted in confirmation of the basic Interchange Configuration– Provision for access to/from South– Validation of layout– Deferral of some work

• The VE found additional savings of $5.9M on $34.5M, a 17% savings

• Addressed planning and political concerns– Future access to/from south– Allowance for future inland Rail Port



Peer ReviewHighway 1 Lewvan Drive, Regina, SHI• The resulting design served or made provision for

all users, existing and future uses• Existing infrastructure was salvaged to minimize

cost• Additional performance was provided at a lower

cost


Cost ManagementJohnson Street Bridge, Victoria, BC

• The Johnson Street bridge was assessed for consideration as a traditional and a P3 project

• Decision was made to proceed with traditional project delivery• Project cost

estimate identified as $78.9M



• A VE study was undertaken to review project scope and to verify the cost

• VE process, from the Information through the Evaluation Phase, was conducted

• Architectural design constrained VE opportunities



• 116 Ideas were generated of which 82 were carried forward for further consideration

• 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

Pasqua CorridorStudy Limits

Pasqua CorridorStudy Limits



• 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.



• 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



• 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


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
