Gibson
City
Middle
School
Eta designed the mechanical systems for a new 23,000
square-foot middle school, which included classroom, gym, cafeteria
with full service kitchen, and band practice areas. Eta combined
chilled/hot water central air handling units with fan coil units to
create HVAC systems that fit the available space while affording the
teachers individual control of classroom temperature. Chilled water
is supplied by an air-cooled chiller with a piping shunt arrangement
that allowed the school to provide cooling to the gym area without
having to bear the cost of a dedicated chiller. Heating is provided
by a bank of eight (8) modular boilers controlled to stage and
closely match heating load, thereby saving energy and preventing
overheating in the ‘shoulder’ season.
Wesley
United Methodist
Eta designed the mechanical, electrical, and plumbing
systems for the addition of 5500 square feet of new classroom spaces
and acoustically sensitive choir practice area. The design also
encompassed retrofitting air conditioning systems to cool existing
classrooms and two kitchen areas. Mechanical ductwork was sized and
designed to fit between and run through the structural trusses. Eta
cut numerous sections to assure that the ductwork was coordinated
with the trusses, and all ducts were subsequently installed without
any change orders.
Triad
Fire Alarm Upgrade
Eta designed the upgrade of existing fire alarm
systems in three student dormitories (the “Triad” complex) at
the
University
of
Illinois
. Eta’s work included
tracing out existing fire alarm system, replacing photoelectric
smoke detectors with ionization detectors, and specifying new
alarming strategy to be programmed into Fire Alarm Control Panel.
In addition, Eta designed the lighting modifications
necessary to accommodate various architectural changes made to
improve the common areas of the dorms.
Housing
Fire Alarm Replacement
Eta designed the upgrade of the existing fire
alarm system in 10 dormitories on the
University
of
Illinois
at
Urbana
campus. The design work
included replacing magnetic with electronic fire alarm horns, adding
strobes where required by the ADA, adding ionization detectors where
required, and analyzing all areas of the buildings to ensure that
fire alarm horns were loud enough.
Outdated “as-built” drawings necessitated that Eta Engineers
perform extensive fieldwork to verify existing conditions. As prime
consultant on the job, Eta performed all construction phase
services: chairing all site meetings, issuance of meeting minutes,
issuance of change orders, review of pay requests, final punch
lists, and final close out documentation.
Lecture Room 218 Remodeling
A well-used lecture room in the historic
Ceramics
Building
at the
University
of
Illinois
, Room 218 underwent a complete renovation to bring it up to the
quality of other University lecture halls.
Eta’s design included retrofitting ductwork for central
air, upgrading the existing lighting with energy-efficient lighting,
and routing voice telephone lines and CAT5 data cabling for the
modern audio/visual systems required in new lecture halls.
All this mechanical and electrical work was designed in close
concert with the Architect on the job to ensure that the historic
nature of the room was not compromised.
All new conduits were routed behind walls, all new ductwork
was hidden inside existing chases, and all new data/telecomm cable
was routed inside wiremold that was integrated with architectural
details. |
