Setting the standardFor engineering excellence

Services

PSA offers extensive experience in the design of mechanical, electrical and plumbing systems for all types of buildings and building construction. Our design approach to every project is to incorporate the client's needs through innovation and positive design. We prefer to think it "can be done" and "never say never". Our mission is to set the standard for engineering excellence through innovative and creative design with a responsibility to the projects' budget demand.

Mechanical Engineering Services

PSA has extensive experience in the design of mechanical and plumbing systems for auditoriums, hospitals, laboratories, low- and high-rise office buildings, medical office buildings, museums, performing arts centers, sports facilities and arenas, and a myriad of other building types that it has been involved with over the past 40 years.

Capabilities:

HVAC Systems

PSA has utilized computerized design tools for its system designs since 1971 when the company was first created. This use has expanded from relatively simple HVAC Heating/Cooling Load calculations using time-shared computers in the early years to use of the TRANE TRACE 700® energy analysis/load calculation program, the TRANE Pipe Designer program, the TRANE TOPSS® Equipment Selection Program, the LINDAB/TLIne CADVENT® three dimensional duct design program, and many others provided by other equipment manufacturers. These programs are all resident on PSA's computers and allow PSA's staff to efficiently generate accurate HVAC systems designs that utilize the most efficient systems for their function.

Energy Analysis

PSA accomplished its first energy analysis in 1972 using the TRANE TRACE® program which was introduced that year. This analysis was the first use of the TRACE program for this purpose in the State of Oklahoma. PSA has standardized on the TRACE® program for its energy analyses and has continued to use the program over the past thirty years for many different facilities. The latest analyses made were for the Oklahoma City Art Museum and both the base and optional Gateway Dormitory designs at Tinker Air Force Base for the Corps of Engineers.

Acoustics/Noise Control

PSA's initial exposure to Acoustics/Noise Control was a great learning experience. The project was a small television studio in Amarillo, Texas done for the NBC Affiliate there. This project was the springboard which PSA used to become a successful Acoustics/Noise Control engineering firm in the years to come. PSA has worked with nationally known Acousticians on many successful projects since that very early Texas project including the NBC Television Studios in Chicago, Illinois, the Quartz Mountain Performing Arts Center in far southwestern Oklahoma, and the Civic Center Music Hall Renovation in Oklahoma City. All of these facilities were designed to noise levels at or below 20 NC and met that design. Other acoustically sensitive projects done solely by PSA staff include the National Cowboy and Western Heritage Museum, the Oklahoma City Museum of Art, and Midwest City High School Auditorium.

Specifications

PSA uses MASTERSPEC® master specifications for all of its projects. These specifications are updated quarterly in order to reflect changes in the industry and changes in the manufacturers of products.

CAD (Computer Aided Drafting)

PSA has utilized CAD for producing construction documents for over 17 years. The first project accomplished using CAD systems was begun in 1985. PSA was fully converted to the use of CAD by 1989 and currently utilizes AutoCAD 2000i® for all projects. Reproduction of our plans is accomplished by a high-speed laser plotter that is backed up by ink-jet plotting systems.

Electrical Engineering

Capabilities:

Interior Lighting Design

At PSA we are especially attentive and sensitive to providing designs that are aesthetically pleasing to the architect/owner and that at the same time provide illumination levels compliant with IES Standards. PSA has utilized computerized design tools for its system designs since 1971 when the company was first created. This use has expanded from relatively simple in-house zonal cavity method lighting calculation programs to incorporation of various vendor programs for specialized applications. These programs are all resident on PSA's computers and allow PSA's staff to efficiently generate accurate interior lighting systems designs that utilize the most efficient fixture/lamp combinations for the intended function.

Exterior Lighting Design

PSA has extensive experience in the design of exterior lighting systems; the most common of which are the designs of outdoor sports facilities including college level football stadium lighting and professional baseball field lighting. Our most recent projects of note include the AT&T Bricktown Ballpark in the "Bricktown" area of Oklahoma City and the Boone Pickens Stadium Renovation for Oklahoma State University in Stillwater, Oklahoma.

Power Distribution Design

PSA's experience in power distribution design is varied and vast. Variation extends from the simplistic involving typical building project distribution with 208Y/120v and 480Y/277v power distribution systems to studies and design of 15KV rated distribution system extensions for industrial facilities or municipalities. Designs generated by the firm range from the design of electrical systems for municipal water or sewage treatment facilities to the design of specialized system for healthcare, broadcast, worldwide reservation facilities with large emergency generator/UPS systems, and cold storage/freezer facilities where designs must accommodate equipment installed and later serviced in a minus 20 degree environment.

Specifications

PSA uses MASTERSPEC®® master specifications for all of its projects. These specifications are updated quarterly in order to reflect changes in the industry and changes in the manufacturers of products.

CAD (Computer Aided Drafting)

PSA has utilized CAD for producing construction documents for over 25 years. The first project accomplished using CAD systems was begun in 1985. PSA was fully converted to the use of CAD by 1989 and currently utilizes AutoCAD 2000i® for all projects.
