Mass Transit - 27

THE EXTERIOR
of CTDOT's
Waterbury
facility.

"... you discover that the footprint of the building
you had in mind would not leave enough space
for the required retention basin. It isn't time
to start looking for a new site; it's time to start
rethinking the design of your facility."

rounding it. Site access is mostly
restricted to one access point and
there is not any available space
to introduce new access roads.
PVTA's facility in Massachusetts
had similar landlocked restrictions, with several industrial
neighbors and a railroad locking
it into having two access points
from the same road. When dealing with this type of constraint,
a thorough knowledge of factors
such as bus circulation, fire department access, code compliance and parking requirements
allows the design and stakeholder group to make critical decisions to make the most of each
site challenge. In these cases, the
entities' willingness to take advantage of vertical space allowed
them to better accommodate all
of these factors within their chosen sites.
Finally, the most important
reason to consider building up
instead of out - looking to the
future. It is essential not to use
every available inch of the site in
your initial design, which will be
especially tempting on a site with
space constraints. By spreading

out over the site, all hope of future
growth and expansion may vanish if adjacent property is unavailable. Both PVTA and CTDOT's
facilities, although working
with similarly constrained sites,
managed to leave ample room for
growth on the south and north
ends of their sites, respectively.

Debunking myths about
construction expenses

By now the logistical benefits
of building vertically should be
plain and obvious, however, many
owners believe that choosing a
multiple level facility greatly increases cost. The truth is, when all
site factors have been evaluated,
going to a multi-level facility may
be the most cost-effective option.
For instance, the foundation
and mechanical systems of single
and multi-level facilities are not
fundamentally different. In fact,
the necessary building height required for lifting buses lends itself
to a second level that effectively
makes use of the rest of that unused vertical space. Additionally,
roof access convenience through
the second floor can provide

walkout access for ease of maintenance. In the cases of CTDOT
and PVTA, the implementation of
elevated administrative offices on
a second level allows for a smaller building footprint on the site,
the benefits of which have already
been detailed.
Sustainable strategies that create workspaces people want to be
in, such as daylighting, are another point in favor of multi-level facilities. Daylighting and exterior
views are not possible from every
workspace on a more spread out,
single-level facility. However, the
smaller footprint of a multi-level
facility gives more opportunity
for exterior views throughout the
building. This benefits worker efficiency, employee retention and
overall workplace satisfaction. For
example, CTDOT's Waterbury facility is designed to Connecticut's
High Performance Building Standard. The second floor allows for
additional window frontage and
views that give the offices a view
of the outdoors. The maintenance
bays similarly boast natural light
and ventilation through an elevated clerestory.
Ultimately, the cost of building vertically is dependent on
the size and scale of the facility
and operation, and each case is
unique. However, successes such
as CTDOT and PVTA's facilities
show that going vertical can be
not only viable but also preferable on sites with space, access or
regulatory constraints.
