PHILIPPINE BIDDING DOCUMENTS (As Harmonized with Development Partners) Procurement of Infrastructure Project MRT3 Capacity Expansion Project Lot 2: Upgrade of Ancillary Systems (Rebid) Government of the Republic of the Philippines VOLUME II : SPECIFICATIONS Fourth Edition December 2010 TERMS OF REFERENCE MRT3 CAPEX Lot 2: Upgrade of the Ancillary Systems 1. INTRODUCTION DOT-MRT3 is planning to increase the line capacity and train capacity of MRT3 by increasing the train configuration from 3-car train configuration to 4-car train configuration running at improved headway not more than 150 seconds during peak hours. With this objective, DOT-MRT3 created CAPEX projects for MRT3, LOT1 which is the procurement of 48 additional LRVs; LOT2 which is the upgrade of the ancillary systems; and LOT3 which is the Signaling System Upgrade. All modifications to improve the capacity of the existing MRT 3 System is purposely to serve more riding public with safe and reliable transport system. These projects are the support capacity improvement of LOT1; LOT2 covers the Power Supply System, Overhead Catenary System, Civil works and Track works and LOT3 covers the upgrade of the Signaling System. 2. MRT-3 SYSTEM DESCRIPTION A. General The MRT-3 System is the cornerstone of the Department of Transportation’s (DOT) integrated strategy to alleviate the traffic congestion along the EDSA corridor. Completed in July 2000, the MRT-3 is carrying a maximum of around 600, 000 passengers daily. The system is built by a private consortium, Metro Rail Transit, Corp. (MRTC), under the Build, Lease and Transfer Agreement with the for a period of 25 years. B. Alignment The line is a 16.9km rail system occupying the median of EDSA with 40% at- grade, 52% elevated and 8% underground or depressed. Running from North Avenue, Quezon City to Taft Avenue in Pasay City, the MRT-3 has a total of 9 elevated, 2 at-grade and 2 depressed stations with side platforms for elevated and center platforms for depressed or at-grade stations. C. Guideway The total length of the MRT-3 guideway is about 16.9km consisting of the Kalayaan Tunnel (515m), At-grade level (7000m), elevated structures (9000m) and steel structure (135 m). It traverses along EDSA from North Avenue in Quezon City to Taft Avenue in Pasay City, designed to fit the existing infrastructures like the Magallanes and Ortigas Flyovers. The elevated guideway structure was constructed using reinforced concrete except for the Guadalupe Bridge, which is made of structural steel. The guideway supports spaces for the Signaling, communication, high and low voltage power distribution systems of the MRT-3. It is made of AASHTO pre-stressed girders with reinforced concrete slab overlay of about 210mm thickness and supported by either column piers or portal frame supports. All guideway foundations are generally bored piles. All design and construction of the elevated guideway are in accordance with the existing Philippines Standards and Code of Practice and/or international applicable standards. D. Tracks The MRT-3 system uses a standard gauge track of 1435mm utilizing UIC 54 rail profile welded together to form continuous rail using flash-butt and alumino- thermic welding process for the mainline. Crossovers are located in North, Cubao, Shaw, Buendia and Taft with an access track to and from the depot located between North Avenue and Quezon Avenue Station. The Mainline has a minimum horizontal radius of 370 m and applies an absolute maximum gradient of 4.0%. For the Depot Access Track, an absolute gradient of 5% is present with zero cant all throughout the depot area and a minimum radius of 25m in the depot curved sections. The mainline track consists of both ballasted and concrete plinth sections. Ballasted tracks are about 7.6km in distance, supported by concrete sleepers, with 750mm spacing. Rail fastening is made through the use of Rail Fastening System laid on the ballast with at least 250 mm depth. Concrete plinth tracks are about 9.15 km long utilizing direct fixation fasteners with 750 mm spacing and supported by a concrete plinth of 220 mm thickness. Remote operation of point switches for crossovers at North, Taft, Shaw, Depot Access Track and at the pocket track at Taft can be carried out from the Control Center. Manual point switches are installed in Buendia and Cubao for maintenance and emergency operation. Automatic point switches are fitted with position detectors that can be monitored from the Control Center while manual point switches are fitted with levers and locks only. Current maximum train speed is at 40 kph and shall be increased to 65 kph after track replacement/rehabilitation. E. Stations There are 13 stations along the 16.9-km stretch of the MRT-3 system. Station platforms are designed to accommodate 4-car train operation with standard platform length of at least 130m. It has two main areas: The Paid Concourse Area that accommodates paid riding passengers; and Unpaid Concourse Area for queuing passengers with commercial spaces, retail shops and other public services. The two areas are divided by the fare collection gates structured to accommodate future expansion. Each station is also equipped with facilities that cater to the elderly and handicapped. All stations are equipped with elevators (lifts) capable for serving handicapped and elderly passengers. Internal escalators are installed inside the paid areas while external escalators are provided in some elevated stations to access concourse areas from street level. F. Depot Facilities A Depot that houses the Light Rail Vehicles is located adjacent to the North Avenue station where the maintenance of LRV(s) is performed and trains are stabled. It has a total area of 84,444m2 which houses the workshop and maintenance facilities and has stabling capacity for 81 LRVs, with provisional space available for additional 40 LRVs. It has facilities capable for light and heavy maintenance works with office spaces for the operation and maintenance management. G. Rolling Stock The MRT-3 system has a total fleet of seventy three (73) Light Rail Vehicles (LRV’s), but four (4) LRVs are currently not in service. These are Cars 70, 73, 03, and 08. The LRV is built by CKD Doprovni Systemy of Prague. It is articulated in three- sections with four bogies (eight axles), designed for single-ended operation. Each has ten double-leaf, electronically-operated, plug-sliding doors (5 on each side), with three center doors having an open width of 1,255mm and two end doors at 861 mm. Each LRV can seat a total of 74 passengers and can accommodate 320 standing passengers for a total of 394 passengers per LRV. The cars are equipped with Automatic Train Protection System (ATP), which collects information from wayside system through balises for the speed monitoring and control. Each car has a Digital Diagnostic System that monitors the defects and assists Train Drivers during failure intervention. Each LRV has four motorized bogies with two traction motors each, controlled by choppers with IGBT thyristors that activates the traction system. Traction and braking can be controlled using the Hand Controller located at each Driver’s Cab. The braking system is composed of Electrical, Mechanical Disc and ElectroMagnetic Track Brakes, operating in synchronous action depending on the brake application.

Power Supply System There are eight (8) Traction Power Substations (TPSS) along the MRT-3 system comprising seven TPSS dispatched along the line, strategically installed in selected stations and one in the Depot, each receiving high voltage supply rating of 34.5KV AC from MERALCO. Each TPSS has two incoming feeders connected to two independent power substations of MERALCO to ensure power distribution in the event of failure of one supply line. The Power Supply Network consists of two sub-networks: The “traction” sub-network, dedicated to supply power for the movement and maintenance of trains.
