Our electrical engineers have
extensive experience in projects involving replacement of
obsolete electrical equipment in existing buildings. These
projects are always challenging because of limited
mechanical room space and the need to keep the building
occupied with a minimum of interruption.
Many projects involve remodel
and expansion of existing facilities. Working with owners,
facility managers, and other design team professionals, we
provide electrical engineering of power, lighting, and
communication systems for critical facilities.
Many consulting engineering
firms provide power and lighting design, but are not
experienced in instrumentation and control systems. J. W.
Sims provides added value engineering for our civil
engineering clients; electrical engineering for the
instrumentation and control systems for water and wastewater
facilities, in addition to the traditional power, lighting
and motor controls.

Complex electrical power distribution systems
incorporate adjustable electronic circuit breakers and electrical
equipment specified for the available short circuit fault duty, arc
flash considerations are becoming necessary for improving worker
safety.
Short circuit and protective device coordination studies are used to
determine the fault duty ratings of electrical equipment, the needed
set points of adjustable devices, and the arc-flash energy present
at various points of the electrical power system.
Emergency power systems are required for most healthcare and utility
facilities, and typically consist of a standby rated diesel
generator, one or more automatic transfer switches, and one or more
electrical distribution branches. Generator systems can be quite
complex for larger facilities.
Our experience includes a large 4MW generator installation for a large hospital facility. The system consists of two paralleled generators each rated
2000KW, 4160V, with roof mounted radiators and exhaust silencers,
and 4160V switchgear. The generators provide standby emergency power
and peak shaving power for a large urban hospital.
