•The target cost (construction budget) was set 3.6% below market, the actual cost was 14.6% below target, and 17.6% below the benchmark. Most of the released funds were used to provide value-adding scope, especially for imaging capability, with the remainder returned to the client.
•Completed 3.5 months ahead of schedule –70 additional days of clinic revenue translating into nearly $1 mil. in the expanded imaging service line functions and additional revenue in the 2006 year.

Purpose Finance Action Example Comments
Developer
Producer
Shopper
Art
Collector
Create something to
sell to others
Maximum available funds or minimum
acceptable ROI
Target cost
Property developer
Create means for producing
products or services
Maximum available funds or minimum
acceptable ROI
Target cost
Oil refiner, healthcare
company, university
Acquire commodities
Ability to afford Buy at lowest
price
Law firm, insurance
company
But note: If facilities are not commodities and
can impact use benefits through different
designs, then Shoppers are actually Producers, and buying at lowest
price is not likely to deliver greatest value.
Create something
without predefinable
properties
Within initially indeterminate limits,
funds can be acquired based on
the attractiveness of the design
Design, then
estimate cost, then
acquire funds
Municipal library,
performing arts theater
At some point, maximum available
funds will constrain the design. That point may
occur earlier or later in the design process.
