TELECOMMUNICATIONS

telecommunications systems design:  Private facility projects generally have the owner's personnel negotiate with the various telecommunications companies to determine the scope of the telecommunications services and to contract for these installations.  Spencer Engineers, Inc. (SEI) normally provides an empty conduit system for these owner furnished facilities that will be installed by a separate contract between the facility owner and a telecommunications company. 

On Federal and military projects, the rotation of personnel will usually mean that the personnel occupying the facility during the design will be different that the personnel occupying and operating the facility after it is constructed.  DoD facility AE design contracts often requires that the AE determine the telecommunications requirements for the facility.  In these cases, SEI has specified the telecommunications systems and equipment for construction and installation into these facilities.  When this is required, SEI utilizes Corps of Engineers and Navy guidelines to specify telephone systems for these facilities.  These system selection decisions are very subjective, subject to personal opinions, and not easily justified technically or economically.   Some base commands have individuals or units that are in charge of telecommunications design, and SEI utilizes their design decisions and incorporates this design into the Construction Contract Documents.  Where large, extensive new or replacement telecommunications infrastructure systems are needed, we recommend a telecommunications consulting firm or the telecommunications engineering staff of the local telephone company be consulted.  Experience forecasting future telephone service requirements and capital investment requirements must be documented and agreed before construction is started.  Telecommunications engineering includes switch specifications, bid evaluations, delivery and installation scheduling, periodic inspections during installation, progress reporting, commissioning and final acceptance tests.  Our consultants have advised on or engineered the following systems:

TELECOMMUNICATION FACILITIES DESIGN:  SEI has 20 years’ experience in the design of the HVAC and electrical systems for electronic telephone communications facilities.  We also have extensive experience with the installation of all types of computers including the CRAY I super computer.  SEI is veterans in the field of 400 Hz power generation and distribution for super computers and avionics, trouble shooting electronic telecommunication and computer installations for the sources of transients, and designing UPS systems.  SEI has worked closely with Southwestern Bell Telephone Company (SBC) in the design of new and remodeled buildings for their equipment.  This included air conditioning and heating, fire detection, fire alarm, electrical power, emergency electrical power, lighting, and in special cases under floor air conditioning and Halon fire suppression for computer equipment.  Temperature and humidity control with redundant back-up is a standard requirement for these facilities.  SEI provided the mechanical and electrical design for the construction of more than 15 SBC (Southwestern Bell Telephone - Houston) electronic switching buildings or building modifications:
