CARROLLTON WATER FACILITY SEWAGE AND WATER BOARD OF NEW ORLEANS

ENGINEERING AND CONSTRUCTION ESTIMATING

Citrine provided conceptual design and project estimating services for various electrical project upgrades at the Carrollton Water Facility. Projects included new and retrofitted pump stations, medium voltage substations, and 20 MW of AC-DC power conversion. For each proposed project, our team provided a technical overview, cost estimates, associated advantages and disadvantages, approximate required time to implement, and an estimated return on investment.

CHEYENNE MOUNTAIN AIR FORCE STATION COLORADO SPRINGS, CO

ENGINEERING STUDIES

Citrine performed reliability and

availability studies to various

power systems within the

Cheyenne Mountain Air Force

Station. Our analysis included a

review of existing equipment,

interconnection configurations,

and IEEE design standards. The final project report supported the

expansion of the station’s electrical systems by improving efficiency,

reliability, and safety in operation.

GSA REGION 10 - OREGON, WASHINGTON, ALASKA

ARC FLASH STUDIES

Citrine performed building surveys

and electrical studies for the General

Services Administration (GSA) in

Oregon, Washington, and

Alaska. Our team of licensed

electricians and professional

engineers documented the

equipment condition and rating

details needed to update electrical one-line diagrams and create a

detailed electrical model of each building’s electrical system. The model

was used to perform electrical engineering analysis including short circuit

studies, protective device coordination, and arc flash studies. The formal

report included equipment and safety recommendations along with high

quality arc flash labels that complied with NFPA 70E safety requirements.

JOINT ELMENDORF-RICHARDSON, ALASKA

BACKFLOW PREVENTION/CROSS CONNECTION CONTROL SURVEY

Citrine performed backflow

prevention/cross connection control

surveys for buildings across the

JBER base – spanning over 400

square miles. We identified all

potential cross-connections and

recommended corrective actions for

any identified cross-connections

found. We inventoried all installed backflow prevention devices,

determined their suitability to the hazard present, and identified any

corrective actions. The goal of providing recommended corrective

requirements actions and ensuring the base’s compliance with Safe

Drinking Water Act (SDWA) requirements was achieved.

MALMSTROM AIR FORCE BASE, MONTANA

ELECTRICAL SURVEY Citrine performed an electrical survey of two buildings on Malmstrom Air

Force Base. Citrine identified the status of the electrical service loads in

the buildings to determine

additional power requirements

in order to prevent overloaded

circuits. We surveyed the power

from each panel, verified the

panel breakers, determined

maximum loading of each panel,

and updated the panel

schedules. We generated a one-

line of each panel with current power loads and the Main Distribution

Panel (MDP).

WESTERN AREA POWER ADMINISTRATION - VARIOUS LOCATIONS

NATIONAL INSTITUTE OF STANDARDS & TECHNOLOGY WASHINGTON, D.C.

ARC FLASH TRAINING

Citrine provided several NFPA 70E

electrical safety trainings for WAPA

and NIST; in-person, and virtually.

The training was based on the 2018

NFPA 70E standard and OSHA

regulations and included low voltage,

high voltage, and arc flash safety

topics. The training was presented by

an NPFA Certified Electrical Safety

Compliance Professional (CESCP). The training included presentation

materials, the NFPA 70E standard reference book, and completion

certificates for all attendees.
