EXHIBIT A – SCOPE OF SERVICES

PS139177 – AS-NEEDED BATTERY SUPPLY AND INSTALL

PART 1 - GENERAL

1.01 DESCRIPTION

A. The Los Angeles County Metropolitan Transportation Authority (Metro or LACMTA) is seeking a qualified Contractor to provide comprehensive, on-call battery system replacement, testing, and support services under an Indefinite Delivery/Indefinite Quantity (IDIQ) Contract. This Contract is a standalone IDIQ and is not dependent upon any other Metro IDIQ contracts.

1. Battery system includes batteries and battery chargers.

2. UPS equipment is handled under a separate contract, however, if a UPS system is deemed defective and in critical need of replacement at the time of battery replacement, this IDIQ could serve as a mechanism for its replacement.

3. Battery racks are to be reused where feasible. If a battery rack is deficient and is required to be replaced with the new batteries, this IDIQ shall serve as a mechanism for its replacement.

B. The Work includes removal, replacement, installation, testing, commissioning, and disposal of battery systems supporting Metro Rail Signals, Traction Power, Facilities Maintenance, and Rail Communications across the LACMTA system, including underground light rail locations. Work will be authorized on an as-needed basis through individual Task Orders issued by Metro.

C. The Contractor shall furnish all labor, materials, tools, equipment, transportation, supervision, and incidentals required to perform the Work in accordance with Metro requirements, industry standards, applicable codes, and this Scope of Work.

1. This IDIQ project is looking to pre-qualify battery system suppliers/vendors for a period of performance of 24 months from notice to proceed (NTP), with three, one-year options.

D. This is an IDIQ Contract. Metro will issue Task Orders defining the specific scope, locations, quantities, schedules, and performance requirements. No Work shall proceed without an executed Task Order.

1.02 PROJECT LOCATION

A. Battery systems covered under this Contract are installed at various Metro Rail facilities, including but not limited to, traction power substations, signal houses, communication rooms, stations, yards, underground light rail locations and maintenance facilities throughout the LACMTA service area.
