Jarrell's successful bids to Sverdrup Corporation resulted in a cool place for hot performers at the Riverport Amphitheatre. In addition, Jarrell reduced installation costs to four new buildings with improved energy and cost-efficient HVAC systems.
Jarrell bases its national reputation on successes like its computer-aided spiral duct distribution systems, designed for and installed in office buildings throughout the country. The spiral duct needs less reinforcement and handles greater air velocity than a more typical rectangular duct.
Less reinforcement means lower initial costs and less noise. Greater air velocity and designing for static regain mean a more efficient air supply. This all adds up to savings for the building owners.
Jarrell is proud to contribute to the long-term success of the Riverport complex with value engineering suggestions that resulted in increased energy savings and lowered construction costs.

How can you cool an open-air stage?
Jarrell engineered a system that encapsulates
air delivered downward from a roof top air
conditioning unit then draws it back in to be
cooled down again. The result, instead of
cooling the hot, humid outside air, the system
cools the unit-produced air and works more
efficiently. The final effect is a wall of cool,
dry air on the outdoor stage. Jarrell’s design
changes to this project saved a third on
installation costs plus provided additional
system efficiency.

Jarrell handled the plan and spec contract
for Riverport’s first building, the
110,000-square-foot Exec I, the hotel and restaurant.
Jarrell incorporated its computer-aided duct
distribution system and engineering expertise,
which increased value to the Sverdrup/Jacobs
design. Jarrell’s enhancements called for
a quiet, efficient spiral duct system that
operates on the basis of static regain to
provide greater energy efficiencies.

After completing the tightly scheduled tenant
finish work on Exec I, Jarrell won the design/
build contract for the 110,000-square-foot Exec
II. Recognizing the benefits of Exec I’s spiral
duct distribution system, Jarrell incorporated it
into Exec II. This project included Jarrell selecting
the equipment, performing a computerized load
analysis, specifying the tonnage on the units,
completing the drawings and system installation.

Next came the Tower, a massive, 11-story,
330,000-square-foot building. Again, Sverdrup/Jacobs
specified the spiral duct design. To handle the
demands of this huge office tower, Sverdrup/Jacobs
and Jarrell reviewed the conceptual central
chiller design and opted instead to utilize
individually packaged units on each floor.
This approach offers the office tower excellent
flexibility, efficiency and reliability.

After successfully completing these large-scale
projects, Jarrell continued working with Sverdrup/Jacobs
on the next important project, the Express Scripts
building. Jarrell is proud to also mention this
building, a 40,000-square-foot prescription order
house with systems engineered, designed, fabricated
and installed by Jarrell.
