1.6 SYSTEM DESCRIPTION

A. General

1. Scope includes renovation of the audio, intercom, and distributed TV systems. Existing systems that are not noted on the drawings or in the specifications shall remain operational and fully functional. Alert the consultant and owner if new work is expected to impact or change functionality of existing systems that aren’t addressed in the documents.

2. Demo scope includes removal of legacy sound system and amplifier equipment. All salvageable equipment, including rack mounted equipment and loudspeakers shall be removed, transported to the truck dock, and palletized for the Owner. Salvage equipment will be reused by the owner or disposed of through the university system. The Owner will mark or designate rack mount equipment that shall remain through demolition.

3. The contractor shall subcontract or directly provide all noted electrical work including additional power and installation of pathways. The Owner desires a turnkey system with one vendor holding the entire scope and engaging subcontractors as needed. Conduit or enclosed raceways shall be utilized for cable containment in occupied spaces. Cabling must be suitably protected, rated, and supported when routed through concealed spaces.

4. Loudspeaker array cabling for chain hoist mounted speakers shall route from amplifiers to grid. The current preference is for speaker cabling to be terminated offsite to SC-32 multipins and pulled unbroken from amplifier to a disconnection panel at grid level via new cable tray and pathways from 7th floor amplifier room along the catwalk systems to the AP grid. This would reduce terminations by several 100 and potentially expedite installation. We invite the contractor to propose other solutions.

5. Contractor and subcontractors must comply with University requirements and agreements which may include requirements for employees working on the project to meet minimum criteria with background checks.
