1-1 Contractor Scope of Work - The contractor shall provide all labor, materials (unless otherwise specified), equipment, transportation, and services, required to perform the following as specified below and shown on the following drawings:

AEX-ARSR-G09 Drawing Index AEX-ARSR-C02 Elevation Views of ARSR & E/G Building AEX-ARSR-C03 ARSR First Floor Plan AEX-ARSR-C04 ARSR Second Floor Plan AEX-ARSR-C05 ARSR Second Floor Plan Electrical & Floor Repair AEX-ARSR-C06 ARSR Third Floor Plan AEX-ARSR-C07 ARSR Fourth Floor Plan AEX-ARSR-E019 ARSR Electrical Panel Schedules

NOTE 1: The AEX ARSR is an operational National Airspace (NAS) facility, and as such, all work that is accomplished at the ARSR must be done in accordance with procedures outlined in this specification; so as to minimize the impact on the facilities customers. Some of the contractor’s work activities within this facility will require a RADAR equipment outage. In an effort to minimize the number and duration of FAA equipment outages; the contractor will be required to perform all electrical breaker panel replacement work during the same time period. Any scheduled outage of greater than 8 hours must be coordinated with our NAS customers a minimum of 30 days prior to the requested outage. This scheduling requirement shall be taken into account when planning the project schedule.

Currently some of the existing light units are not controlled by room switches (they remain on all the time). It shall be the contractor’s responsibility to ensure that all light fixtures (new and existing) are controlled by operational room light switches. In some instances this will require that the contractor identify and correct switch problems.
