2. Engineer The person, firm, or corporation named as such in the contract and/or authorized by the County to act as the County’s project manager or the County construction engineer authorized to practice engineering services pursuant to Section 471.03(2)(i)(2006), Florida Statures, and who may serve as the County’s engineers of construction, engineering and inspection. The term engineer shall be synonymous with design architect/engineer or architect/engineer or consultant.

3. Contractor Project Manager or Project Manager The individual responsible for the day-to-day administration of the project for the Contractor.

4. County The County of Volusia, Florida, a political subdivision of the State of Florida for whom the work or services is to be performed by the Contractor.

5. Service Providers is an organization who provides access to the internet (ISP), telephone (TSP), television (TVSP) or other services for accessing, using, or participating in voice, data and television services. Service providers may be organized in various forms, such as commercial or privately owned.

B. Type of Sites

1. Owned Site A location owned, operated, maintained and designed by the County.

2. Leased Site A location defined by a formal agreement between the County and the location owner in which the location is designed, operated and maintained by the County for a specific length of time.

3. Temporary Site A location that is normally short term for a specific event or emergency situation and can be on County property or on leased space.

C. Types of Technology Systems Rooms

1. Telecommunication Services Entrance Room, TSER This is the point of presence (POP) for the local services provider. Service personnel shall troubleshoot their systems up to this point. This is normally considered a “wet” room and design consideration shall be taken.

2. Main Distribution Facility, MDF Sometimes referred to as the Equipment Room (ER) or Telecomm Room (TR). This is the first point of

Release 12.04.15 Page 2 of 9 27 00 00

The County of Volusia 27 00 00 Division 27 Technology Guidelines COMMUNICATIONS

technology systems management for any building. This room is sometimes combined with the TSER to save space. This is the location where underground backbone cabling meets building riser cabling and can also distribute horizontal UTP (unshielded twisted pair) cabling. Rack mounted application servers reside here and wall space is used for individual system termination cabinets. This room can use as much as fifty (50) watts per sq ft (square feet) and five (5) KW (kilowatt) per cabinet or rack. This room shall be on emergency power.

3. Intermediate Distribution Facility, IDF The IDF is the Horizontal Cabling distribution point for a building or a floor. It provides a coverage area with a radius of two hundred ninety (295) feet in all directions. This room is an extension of the campus or building network infrastructure to the MDF. In multiple floor buildings the MDF and IDF’s should be stacked and located near the core of the building. This room can use as much as twenty (20) watts per sq ft and five (5) KW per cabinet or rack. This room shall be on emergency power.

4. Data Center, DC This facility is used to house computer systems and associated components, such as technology and electronic data storage systems, application servers, redundant back-ups, contingency equipment and special security systems. They generally include redundant or back-up power, communications connections and environment controls. Data Centers can use as much as one hundred (100) watts per sq ft and ten (10) KW per cabinet. This room shall be on emergency power.

5. Network Operations Center, NOC The NOC is designed not only for network monitoring and control but also for all of the support systems: environmental conditions, electrical consumption, security, life safety or any system that touches the infrastructure. This space usually contains user work stations and a video presentation wall.

1.3 DESIGN PLANNING AND SCHEDULING REQUIREMENTS

A. Project design process approach is determined by the architect and is dependent on time schedule available. Most projects use a four (4) tier process.

1. 30% Schematic Design, SD General concepts, building layouts, locations and size of MDF/IDF (120 sq ft minimum) can be in a “Narrative” form.

2. 50% Design Development, DD System specifics, all technology system end user devices should be located on floor plans. MDF/IDF enlarged floor plans should include rack layouts and elevations and room wall elevations. Issue technology T-series drawing index.

1.2 SYSTEM DESCRIPTIONS

A. The Contractor shall provide sound systems complete with all accessories as a turnkey solution. Include all parts and pieces for a complete and functional system, including training.

B. A public address (PA) system is usually defined as electronic sound amplification in common public accessible areas. Announcements can be live or recorded and even from a remote location. These systems are often found in auditoriums, sport parks, commercial buildings, and outdoor venues, just to name a few. PA systems are usually used for speech applications. Many PA systems interface with telephone systems for paging access.

C. A sound reinforcement (SR) system is very similar in components as the PA system, but usually found in smaller venues like training rooms, outdoor areas and larger conference rooms.

D. An intercom system is an intercommunication device which allows for monitoring and talkback. It is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public address and telephone systems. Intercom systems can be zones for access.

E. Sound masking is the addition of natural or artificial sound (such as white noise or pink noise into an environment to cover up unwanted sound by using auditory masking. Sound masking reduces or eliminates awareness of pre-existing sounds in a given area and can make a work environment more comfortable, while creating speech privacy so workers can better concentrate and be more productive.

F. An assistive listening device (ALD) is used to improve hearing ability for people in a variety of situations. A common usage is to aid people who are hard of hearing (HOH). The ALD may be used to help HOH people hear televisions and other audio devices and also to help people hear speech through public address systems such as in auditorium or at a lecture. These systems should be included in the design of any County large public venue.

G. The nurse call communication system ties into the local PA and is used to communicate between the patient and the duty stations and the individual attendants.

H. Code blue systems are usually found in public areas like parks and parking lots. The system includes freestanding pedestals with voice connections to a monitoring service or 911 and an alert light. Newer devices can include CCTV cameras.

I. A master clock system is a precision clock that provides timing signals to synchronies slave clocks as part of a clock network. The master clock system

Release 12.04.15 Page 2 of 4 27 50 00


includes the devices, cabling, software and licenses. Many times the clock system also provides program signals. Many of the newer system are now wireless.
