Value management has evolved out of the concept of value and function, pioneered
by Lawrence D. Miles in the 1940’s and 50’s who developed the
technique of value analysis (VA) as a method to improve value of existing
product. The institute of value management.
The definition of value is, “something well worth the money; ability
of a thing to serve a purpose or cause an effect” (oxford dictionary).
Value engineering or VE should consider a) is it worth the money and b)does
it serve the required purpose.
To value Engineer it should include three parties working closely together,
the user, designer and builder. The user who is not necessarily the client
in contractual terms needs to convey the way they will use the project, the
designer can ensure the product meets the criteria and the builder can ensure
the product is worth the money.
Typically VE falls into two streams;
Finding a lower price
Re-Engineering
To ensure value, the three parties need to collaborate.
The process is often paid lip service, with a contractor putting forward
a cheaper product and the consultant rejecting the product because its not
the same. Often suppliers assist in the design process which can involve writing
specification which make finding the same product impossible.
With PFI and PPP there is a real awaking by the construction industry to
consider the Facility management cost (FM) or wholelife cost. The capital
cost of a product is often dwarfed by the maintenance and energy cost of the
product, but these costs are often not fully appreciated. How can a designer
know the maintenance cost, this is where the clients benefit from the contractors
early input, particularly where they can offer maintenance.
The designer can prepare energy cost models, but only if they have input
from the facility user. Therefore collaboration has the greatest chance of
ensuring value is met. Value for the user might be different to value seen
by the designers, builders or FM. For example energy efficient products carry
tax incentive breaks in the form of enhanced capital allowance ECA, where
they are selected from the energy technology list, but are of little use if
the client is not the user or is a charity or public body.
A client and user should begin the collaboration process early to avoid
good ideas being left on the drawing board.
