COLUMN ENGINEER'S NOTEBOOK
replaced but was not reliable enough to
use. They learned to watch the weather
forecast and start the system manually
if snow or ice is predicted.
We also found it important to be vigilant
for field changes. Design of the
stair treads and underside insulation
had been carefully coordinated during
the design phase. During construction,
the thickness of the granite stair treads
was increased. We were not aware of
the change, and it resulted in lessthan-optimal
snowmelt performance
on the stairs. Due to the thicker granite,
the system took longer to heat the
treads to a temperature warm enough
to prevent snow and ice accumulation.
Conclusions
Overall, the City has been very happy
with the system. It has improved the
north entry's overall function, especially
for mobility concerns. Because
it uses recovered heat, the cost to
operate is minimal. It also eliminated
the need for snowmelt chemicals that
damage the concrete and granite surfaces
and pollute runoff water.
A key point to keep in mind when
implementing creative " outside the
box " ideas is to always have a backup
strategy in case your idea does not
work exactly as you planned. Many
one-off designs end up having results
we do not anticipate, and we cannot
predict all consequences. In this case,
the steam bundle in the tank was our
backup strategy.
It is also important to understand
your client's operating and maintenance
capabilities. If they have talented
staff that embrace new ideas, a
creative and innovative design might
be the right solution. On the other
hand, if the operating staff is stretched
thin, a simpler solution with modest
energy savings may be better.

PHOTO 4 Snowmelt system.
PHOTO 5 The snowmelt system covers the north sidewalk, new stairs and ramp and the entry plaza. The accessible
ramp is on the far left and is partially hidden by the concrete wall of the new plaza.
PHOTO 6 Signs are placed on top of the sidewalk, rather than embedded in it, which would have damaged the
snowmelt system. Signs also are posted to alert crews of the systems' existence.
