Target Costing

October 28, 2008

Presentation OutlinePresentation Outline

• 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)

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)
