The Word we Live By
We are what we repeatedly do. Excellence, then, is not an act, but a habit.
Electricity is really just organized lightning.
The world we have created is a product of our thinking; it cannot be changed without changing our thinking.
At its heart, engineering is about using science to find creative, practical solutions. It is a noble Profession.

Weather Observation systems
This system includes installations of towers with wind monitoring instruments at three mountaintop sites (Sheep Mountain, Mount Roberts and Eaglecrest), a low mountaintop (Pederson Hill), and a station mid-field on the airport runway.
It also includes three Doppler Effect Radar Transmitter-type wind profilers located at the base of Eaglecrest Road, Douglas Harbor and the new CBJ Police Station. The data collected from all sites is transmitted to a laboratory at the airport for manipulation and re-transmission to the Automated Flight Service Station (AFSS), National Weather Service (NWS), Alaska Airlines (ASA), and the National Corporation for Atmospheric Research (NCAR). This system controls use of special arrival and departure routes for the large air carriers with inclement wind conditions. For Haight & Associates, this project involved the design, contract document development, and construction management as well as construction administration. At request, H&A Staff monitor the sites remotely on a day-to-day inspection basis and visit the sites as needed.
Power, Lighting and Signal Systems
These systems include those for fire alarms, fire protection, access control, surveillance cameras, and security. The firm has worked with many varieties of fire alarm and fire protection systems. Originally, the systems involved stringing several initiating devices in a single loop, connected as zones. Now the technology allows the use of addressable devices such that many devices can be connected to a loop, yet each device is identifiable at the control panel. Haight & Associates is quite familiar with both types of fire alarm system, as well as dry chemical, CO2, halon, and water sprinkler fire protection systems. With the restrictive use of halon, and with the technical improvement of the fire alarm systems, many areas are now being configured with pre-action fire sprinkler systems requiring the action of both fire alarm devices and sprinkler heads for water to flow. Their recent work with these systems includes a Halon system upgrade for the Sheldon Museum in Haines and the alarm system replacement at the Capitol in Juneau.
Communications and Data Systems
The configurations of data and communication systems are continuing to evolve very rapidly with the demand for faster communications with larger bundles of data. Haight & Associates is maintaining pace with the industry understanding requirements for the system infrastructure. The staff is currently involved with the installation of networks with fiber optic cable backbones, copper wire terminal wiring for use with personal computers and telephone communications, and wireless routers. Additionally, work continues utilizing radio and satellite communication from remote sites for both data images and voice.
Controls and Instrumentation Systems
Controls and Instrumentation are a part of every project with elements varying from simple to complex. Haight & Associates are routinely involved in assisting with controls and instrumentation for Lighting, Motor Controls, Power System Protective Relaying & Monitoring, HVAC, Power Plant Controls, Process Controls including relay technology and PLC’s.
Lighting Systems and Control
Many of the Haight & Associate, Inc. projects involve lighting Systems. The staff is well-versed in the application of lighting for office buildings, schools, industrial plants, warehouses, waterfront facilities, exterior areas, roadways, and walkways. The staff utilizes computer modeling to assist with the evaluation of optional lighting systems. Control systems vary from simple application of manual switching, occupancy controls, programmable low voltage controls, to architectural dimming control, to use of daylight control with photoelectric switches & dimming, to sophisticated software controls schemes. They understand the advantages and disadvantages of different types of light sources and fixtures for various applications.
Grounding systems properly is crucial to operations as well as the safety of personnel. Haight & Associates, Inc. has extensive experience involving normal conditions as well as special conditions. The most sensitive areas of grounding include the systems for waterfront power loads, power plants, computer facilities, health care facilities, and tower lightning protection systems.
Uninterruptible Power Supplies and Transient Surge Suppression
Over the past twenty years, computer facilities have transitioned from ones with large mainframe computers to systems involving distributed servers outside the main computer facility, and now back to many distributed servers located in a complex network inside larger computer facilities. The facilities are being upgraded with new uninterruptible power supplies, power distribution, and security control.
