Forget about fast track. Construction
schedules today have accelerated so quickly that the old distinction
between traditional and fast-track scheduling has all but
disappeared. Today, fast track is the norm, and what is some-
times called "hypertrack" is growing. And our industry
is suffering.
Without speed limits, the road grows perilous. Having worked
on some hypertrack jobs, we can see the perils pretty clearly.
We can suggest some ways of fending off danger but some of
these solutions carry drawbacks of their own.

Usually there is a compelling reason for putting a job on
hypertrack: A business is renting space until its new facility
is completed and must vacate that space by a certain date;
A college must open a new academic building by the start of
the term; A casinos investors are hemorrhaging money
every day roulette wheels arent spinning.
But there are equally compelling reasons for approaching
hypertrack with extreme care. With hypertrack, construction
begins before design is completed. Once construction starts,
the program cant be changed and design cant be
significantly altered without causing huge change orders or
seriously impeding the schedule.
Success depends on just-in-time delivery of materials and
equipment and on the meticulous sequencing of trades. Even
a slight delivery delay or sequencing snafu can spell disaster.
Hypertrack renovations are especially risky. A skin-of-your-teeth
schedule may leave no time for an adequate survey of existing
conditions and there is no telling what problems you will
run into once you look behind walls, above ceilings and under
floors.
Granted, there are strategies for controlling risks, such
as prepurchasing long-lead equipment and materials and sticking
wherever possible to standard, locally available materials.
Limiting design statements to a buildings public areaseverything
else should be plain vanillaalso helps, as does choosing
a construction manager who already has a good working relationship
with the architect and insisting that the job be run by top-level
personnel with previous hypertrack experience.
Make sure the onsite materials-staging area is adequate so
that early or late deliveries wont wreak havoc. And
never undertake a hypertrack renovation without a comprehensive
exploration of existing conditions.
But even if every precaution is taken, there is still reason
for worry about the outcome of a project and the long-term
effect of the hypertrack approach on the construction design
professions. For instance, putting an owners rep- resentative
on site every day might speed up a project, but only if the
owners rep actually has the power to call the shots
for the owner. If not, you are uselessly adding another bureaucratic
layer and the schedule will suffer.
Hypertracks overreliance on top-level, experienced
personnel also has its downside. It gives junior architects
and engineers too little chance to "get their hands dirty."
Sure, you wouldnt put a student driver in a NASCAR race,
but because hypertrack projects dont allow for a learning
curve they interrupt traditional apprentice processes needed
to train the next generation of designers. The simplified,
cookie-cutter approach to design that hypertrack projects
require also handcuffs architects creativity and can
stifle younger designers ambition for excellence.
Hypertracks greatest perils emerge when owners are
unaware of all the risks. It is incumbent on designers and
CMs to tell owners about all of the hurdles a hypertrack project
faces. If an architect or CM agrees to a hypertrack job too
readily without raising any red flags, an owner ought to be
suspicious. Such eagerness might signal inexperience, or simple
desperation.
Still, hypertrack scheduling might be the only option for
some projects. But owners should proceed with caution. And
we believe the design and construction management professions
should put the brakes on the trend toward making hypertrack
the industry standard. Sometimes there is such a thing as
going too fast.
