Many of the more comprehensive proposals of a value engineering (VE)
study are declined because they are proposed too late in the design
process (i.e., 20%-30% completion). This is because implementation of
these proposals would require modification of the DEIS (Draft
Environmental Impact Statement), EIS (Environmental Impact Statement), or
EA (Environmental Analysis). Modification of these documents would
obviously create considerable project delay and/or cost overruns.
Therefore, the earlier a value engineering study can be conducted during
the environmental planning process, the earlier the larger-scope proposals
(i.e., those proposals that can save more money) can be implemented
without obviating potential savings and creating project schedule
disruptions.
The obvious earliest stage to conduct a VE Study is during the
Environmental Assessment (EA) or Environmental Impact Study (EIS).
However, only a few VE Studies (CALTRANS and the Utah DOT have done one
each) have been done at these stages. The most likely reason for not
doing studies at this stage is that a traditional VE Study has to have a
base case against which to measure value improvement most commonly
measured in life-cycle cost savings. With a little incrementing of the VE
Job Plan it is possible to do formal VE Study during an EA or EIS and
achieve the best of both worlds.
