GENERAL CONDITIONS & SPECIFICATIONS

The Barrow County School System seeks competitive bids for upgrading audio systems in gyms and cafeterias at various middle and high schools as per the general conditions here and specific task criteria to follow. General goal is to augment (where existing system is deemed to be worth keeping) or to replace audio systems to meet general and specific conditions below.

GENERAL CONDITIONS

1. Proposed audio systems must integrate directly with the school’s existing Audio Enhancements intercom and emergency alert infrastructure.

2. The systems shall be capable of being used as a completely independent audio system for various applications as well as an integrated system with the building’s intercom / alert system.

3. Proposed audio systems must be configured for emergency alert infrastructure to have priority, muting any other inputs and presenting announced alert at a guaranteed minimum volume to ensure that emergency messages and announcements are clearly heard above all other audio sources and are heard over the sound of activity in the gym/cafeteria, while not exceeding safe decibel levels.

4. Cafeteria AV systems shall be designed to support a multi-use, multi-audience environment, providing clear, intelligible audio reinforcement for daily dining periods, school assemblies, after-school functions, community events, and large-group instructional activities. The system must ensure that all announcements—local, building-wide, and emergency—are delivered with uncompromised clarity and high speech intelligibility throughout the space. The system shall be capable of being used as a completely independent audio system for various applications as well as an integrated system with the building’s intercom / alert system. Cafeteria systems must provide audio in kitchen/back-of-house areas suitable to ensure intercom and alerts can be heard over kitchen noises during food preparation and cleanup.

5. Gymnasium AV systems shall be designed to be a multi-purpose sound reinforcement and paging/alert system capable of supporting a wide range of school and community activities. These uses include physical education classes, athletic competitions, assemblies, after-school functions, community events, and large-group instructional activities. The system must ensure that all announcements—local, building-wide, and emergency—are delivered with uncompromised clarity and high speech intelligibility throughout the space. The system shall be capable of being used as a completely independent audio system for various applications as well as an integrated system with the building’s intercom / alert system. Specific consideration for intercom/emergency alerts must be given to locker room areas and they must be considered part of the gym audio space.

6. Proposed audio systems must allow for integration of external AV components, including interactive flat panels, existing projector systems, and other sources that presenters may bring to the facility. Audio from these devices should be routed through the proposed audio system to ensure consistent volume levels, proper equalization, and clear intelligibility throughout the room space, while not exceeding safe decibel levels.

7. The overall system architecture should be future-proofed to allow for additional zones, inputs, and technology upgrades as district needs evolve, without requiring wholesale replacement

8. Barrow Board County of Education is exempt from all state sales tax, federal excise tax, property tax, etc.

These taxes shall not be included in the quote.

9. Include digital copies of the manufacture catalog and/or brochure showing a picture of each proposed item along with details such as mfg model, item description and specifications, and site requirements.

10. All equipment proposed must be brand new and not include any remanufactured or refurbished components, frames, or parts.

11. The quoted price must include any assembly, programming, training, and/or other installation fees and charges.

12. The vendor is responsible for removal of debris from Barrow County Board of Education schools and offices the same day installation takes place.

13. Describe warranty/maintenance/support procedures and contact information, and guaranteed response times for service calls. Describe post-installation non-warranty support services available.

14. All vendors must provide three (3) business references having the proposed or similar equipment in operation in similarly sized installations. The listing shall include contact name, email address, and phone number.

15. Equipment specified in specific tasks below is representative of one design option. Alternatives in equipment specifications or overall design are acceptable. Vendors proposing alternatives must thoroughly describe the capabilities and functionality and how the alternatives are equal to or exceed the specified equipment.

16. For each room location, vendor must provide a detailed list of all components, a narrative describing how the system will function at the location, and a cost total for the specific room location. Depending on total costs, district may elect to accept proposal for some, all, or none of the room locations, so individual location cost breakdowns are required.
