• Client Budget Constraints• VE Job Plan for Target Costing • Sample Projects
•Building•Roadway•Sewage Treatment Plant
•Questions
Client Budget ConstraintsClient Budget Constraints
VE a tool for:– Innovation– Cost control– Cost effective/budget control ( maximize every
dollar available to clients)Pre-workshop phase defines the magnitude of the constraint.Is there a fixed budget for the project and an estimate that significantly exceeds it? If yes – consider target costing
VE Job Plan VE Job Plan
VE job plan can led to:– Innovative proposals that can improve value
(better performance at little or no change to project cost)
– Proposals to reduce scope (unnecessary or unwanted functions) with no change to performance
– -Cost savings related to greater reduction in cost than reduction in performance
Target Costing leads to greater ideas in all three categories
Target CostingTarget Costing
Forces organized definition of resources to match budgetWhat is the best project that can be delivered for the budget ….not what is the best project that can be deliveredForces value judgement on worth to the customer (consensus building on difficult decisions)
Target Costing StepsTarget Costing Steps
VE Job Plan uses functional analysisModern analyses use FAST diagrammingConventional Functional Analysis –Focuses on components/functions/costs and worth (best Suited for Target Costing)

Key IssuesKey Issues
Meeting the objectives of SOHP i.e. resurfacing, passing lanes and bridge replacementTraffic volumes generally 20% lower than existing conditions in 1992Crosby Creek Bridge immediate need for replacement
Project FunctionsProject Functions
Highest Order Goals– Satisfy Users– Satisfy Stakeholders
Basic Function– Improve Mobility– Improve Safety
Supporting Functions:– Protect Environment– Limit Property Impacts– Maintain Access– Accommodate Other Users

Ideas developed based on functional analysis and prioritizationTeam included design and independent TeamIndependent Team had expertise to support size reduction of tankSacred Cow was the roof- Landmark Design of design teamSub-team reported back to team. Did not reach target cost. Advised to return until target cost reached. In doing so roof was identified as secondary function that had to be eliminated to reach target cost
SBRSBR--03/1303/13Description– Optimize SBR size
Reduce size by 1/3Reduce blowers from 6 to 4
Advantages– Lower capital cost– Provides adequate treatment
Disadvantages– Needs to be confirmed through modelling (additional
cost $20,000) Cost Implications– Cost Savings up to $885,000 (includes roof removal)
