DESIGN CRITERIA

260000 - 1

SECTION 260000

PART 1 – GENERAL

1.1 DESCRIPTION

A. This project consists of complete replacement of the existing Leviton centralized lighting control system and associated light fixtures.

B. The lighting controls replacement portion of this project consists of a complete replacement of the existing Leviton central lighting control system with a new networked lighting control system that meets the requirements of these Division 26 specifications and the related drawings.

The new Dali compliant lighting control system shall match the function and user interfaces of the existing system, and shall be fully furnished, installed, and tested to demonstrate proper functionality of all system components.

Central control panels or processors shall fit in the same location as the existing control panels or in other areas designated by the Resident Engineer as acceptable to receive panels. Maintain required access and clearances.

Signal rooms can be utilized if there are no available wall space in the electrical room. Both Electrical and Signal rooms to use are identified in the plans. A new, remote Lighting Control System server (complete with all required hardware and software) shall be provided and located in adjacent building B100, and shall be integrated via BACnet to the existing campus BMS. Provide under this contract for the work required to connect the remote server to B500 and the work required integration work within the BMS to provide a completely integrated system, with all the functions specified in Division 26.

C. All existing lighting controls that are standalone (i.e.

not connected to the existing central Leviton control

260000 - 2 system) shall be left in place, and shall remain operational after completion of this project.

D. The light fixture replacement portion of this project consists of replacing all existing interior light fixtures connected to the existing Leviton central lighting control system with similar fixtures that use LED lamps. New fixtures shall meet all the requirements of these Division 26 specifications, and shall match existing luminaires, to the maximum extent possible, in style, size, lumen output, color temperature, etc. as described further in theses Division 26 specifications (except where specifically noted otherwise). Light fixtures connected to the existing Leviton system that are not being replaced are limited to interior courtyard fixtures and fixtures exterior to the building. Some light fixtures are being replaced with higher lumen output fixtures: these fixtures are specifically noted on the drawings.

E. Since there are numerous fixtures that are only locally controlled (i.e. not connected to the central Leviton system and thus not replaced), the contractor shall provide with their bids the quantities of fixtures that are being replaced, organized by fixture type (using the same Fixture Type Tags as used in the Record Drawing’s Light Fixture Schedule/Submittals/O&M Manuals).

F. Where existing lighting control relay panels are removed, reconnect all power circuiting feeding the existing light fixtures. Maintain the existing circuiting: ensure that existing relays fed from each circuit are reconnected to the same existing circuit. Provide the Commissioning Agent with a list of all rooms/areas/fixtures associated with each circuit.

G. The VA Resident Engineer shall provide bidders with full access to the facility prior to receiving bids, and shall provide bidders with all relevant As-built and/or Record Documents in order to allow bidders to assemble complete pricing proposals.

260000 - 3

B. Provide labor, materials, and accessories required to provide complete, operating lighting, lighting controls, and electrical systems. Labor, materials or accessories not specifically called for in the Contract Documents, but required to provide complete, operating electrical systems shall be provided without additional cost to the Government.

1.3 QUALITY ASSURANCE

A. Comply with the current applicable codes, ordinances, and regulations of the authority or authorities having jurisdiction.

B. Specifications, Codes and Standards establish the minimum requirements. Where requirements differ, the most stringent shall apply.

C. Should any change in specifications be required to comply with governing regulations, notify the VA Resident Engineer prior to submitting bid.

D. All electrical equipment, materials, devices and installations shall meet or exceed minimum requirements of

ADA, ANSI, ASTM, IEEE, IES, NEC, NEMA, NETA, NFPA, OSHA,

UL, and the Local Fire Marshal.

E. Execute work in strict accordance with the best practices of the trades in a thorough, substantial, and workmanlike manner by competent workers. Provide a competent, experienced, full-time Superintendent who is authorized to make decisions on behalf of the Contractor.

F. Equipment shall be certified for use in Federal projects.

260000 - 4

1.4 EXAMINATION OF SITE

A. Prior to the submitting of bids:

1. Visit the project site and become familiar with all conditions affecting the proposed installation and make provisions as to the cost thereof.

2. Evaluate existing conditions which may affect methods or cost of performing the work, based on examination of the site and other information available prior to bid. These Contract Documents and other documents provided by the VA Resident Engineer do not make representations regarding the character or extent of the actual existing architectural, structural, mechanical and electrical installations which may be encountered during the work.

3. Review the installation in sufficient detail to determine if the as-built conditions are accurately reflected in the material provided by the VA. Bring any discrepancies to the attention of the VA Resident Engineer a minimum of five (5) working days prior to submission of the bid. Take measurements and such other information as to locations, depths, capacities, details, anchorage, integration with adjacent construction and sizes of existing systems to which connections may be made or which may be abandoned or which require rerouting. If any of the above requires work, the Contractor should include this work in their bid or request clarification from the VA Resident Engineer a minimum of five (5) working days prior to submission of the bid. If additional work is required after the contract for the work is signed, and if such work could have been anticipated by examination of the site before bidding, as solely determined by the VA Resident Engineer, then the corrective additional work shall be performed at no additional cost to the Government.

4. Failure to examine the site, the record documentation, and other information provided prior to bid does not

260000 - 5 relieve the Contractor of responsibility for the satisfactory completion of the work.
