SECTION 01010 SUMMARY OF WORK PART 1 - GENERAL 1.01 DESCRIPTION OF WORK A. This specification covers the rehabilitation of the Wayne Junction Static Frequency Converter (SFC) Station. The work will be executed through multiple prime contracts representing significant elements of work for each Contractor. B. The Work shall be performed concurrently and in close coordination with the respective Prime Contractors listed in these construction documents, and possibly other trades working at the site. The Contractors for this project include: 1. Contractor for General Construction Work (to be known as “General Contractor” - GC). 2. Contractor for Mechanical Construction Work (to be known as “Mechanical Contractor” - MC). 3. Contractor for Electrical Construction Work (to be known as “Electrical Contractor” - EC). 4. The EC Contractor shall be designated the Coordinating Contractor. C. A separate Contract will be awarded for the design, supply, installation supervision, testing, and commissioning of the separate SFC equipment system contract (to be known as “Static Frequency Converter Contractor” - SFCC). D. Brief Description of SEPTA’s Traction Electrification System 1. SEPTA operates a comprehensive transportation system in the Philadelphia metropolitan area and suburbs. The Regional Rail network of commuter lines is an important part of SEPTA’s service. The Regional Rail operates on tracks and systems formerly owned by the Pennsylvania Railroad (PRR) and the Reading Railroad (RRR). 2. The former Reading Railroad system is electrified at 36/24/12 kV, 25 Hz, single- phase, by an autotransformer system. Traction power is supplied from SEPTA’s three existing static frequency converters (SFCs) located in Wayne Junction, PA. This project program includes the addition of a fourth SFC at Wayne Junction SFC Station and the sequential replacement of the three existing Wayne Junction SFCs with three new SFCs. 3. The Wayne Junction converter output transformer has three bushings on its secondary side: 12 kV trolley, 24 kV feeder, and a solidly-grounded rail connection tapped at 1/3 of the secondary winding. Voltage measured from trolley-to-feeder is 36 kV, trolley-to-rail is 12 kV, and feeder-to-rail is 24 kV. E. The Work generally consists of, but is not limited to, the following: 1. The design, supply, construction, testing, and commissioning into full service of four new SFC systems, with an input of 13.2 kV, 60 Hz, 3-phase and an output of 36/24/12 kV, 25 Hz, single phase. The continuous full-load power capacity of the new SFCs shall be not less than 15 MVA. The total station capacity shall be 60 MVA with all four SFCs in operation. Wayne Junction SFC 01010-1 60% Design Submittal Rehabilitation Project November 29, 2016 Table 1 - New SFC Requirements Parameter Value Total capacity of station 60 MVA Number of converters 4 Rating (each unit) - continuous 15 MVA Rating (each unit) - overload 18 MVA for 1 hour 24 MVA for 6 minutes 30 MVA for 30 seconds 4000 A for 2 seconds at 12 kV followed by 15 MVA for 1 hour before next overload cycle 2. Each new and replaced SFC shall be fully interoperable and compatible with the existing SFCs so that it can perform its function either alone or with any combination of the existing SFCs on line. 3. The new SFC equipment will be supplied as part of a separate Contract and shall have an expected lifetime of no less than forty years. The equipment supplied with the SFC system includes the following: a) SFC power block equipment b) SFC input and output transformers c) SFC harmonic and power factor correction filters d) SFC precharging circuit breakers and auxiliary transformers e) SFC control system f) SFC cooling system, including pumps, piping, and heat exchangers g) SFC power distribution system and UPS equipment h) SFC protection system equipment i) Sequence of events recorder j) Transient disturbance recorder k) Remote terminal units (RTUs) l) SFC interconnecting cabling, conduits, and accessories 4. The construction of a new building for the fourth SFC, attached to the existing SFC #3 building. 5. Modifications to the existing SFC Control Room for SFC control and protection equipment for the new SFC system. 6. A new isolation switch and protective relays to be supplied and installed in the existing Wayne Junction 25 Hz Traction Power Substation. 7. The existing 25 Hz Traction Power Substation 12 kV and 24 kV protection schemes shall be recalibrated in order to incorporate SFC #4.

The replacement of the existing Pyrotronic suppression/fire alarm control panels with a new updated addressable fire alarm system and a Halon suppression activation panel in the Wayne Junction 230 kV substation and SFC building. 9. Renovations to the existing SFC building, including architectural, structural, mechanical, electrical, and plumbing work. 10. Electrical duct bank installation between the 230 kV Control Building, the SFC Building, and the existing 25 Hz Wayne Junction Traction Power Substation to support the new SFC #4. All existing power and control duct banks supporting SFC #1, #2 and #3 will remain. 11. All existing filter equipment in the 60 Hz and 25 Hz Filter Yards will be removed, but the existing foundations and associated equipment with the open-air bus system will remain. A new open-air bus system will be constructed to support the new SFC #4 on the 60 Hz and 25 Hz sides of the SFC Building. 1.02 RELATED WORK A. Agreement B. Section 01011 – Summary of Project C. Section 01025 – Measurement and Payment D. Section 01041 – Project Coordination E. Section 01060 – Regulatory Requirements and Safety F. Section 01400 – Quality Requirements 1.03 QUALITY CONTROL AND QUALITY ASSURANCE A. Each prime Contractor will assume responsibility for executing a quality control and quality assurance program. This program’s basic form will be specified in their Quality Control Plan as submitted under Section 01400 and will include the tests & inspections called for in the technical sections of the specifications. Each prime Contractor shall be responsible for requiring all subcontractors and suppliers to adhere to their Quality Assurance Program and participate in quality assurance activities. B. Where governed by “Buy America” requirements, SEPTA will require documentation to confirm the country of origin of all applicable products and materials. Each prime Contractor is responsible for communicating Buy America requirements to their subcontractors and suppliers. The lack of sufficient documentation will be grounds for rejecting a product or material. C. Quality activities will be documented by the Contractor. SEPTA may audit the Contractor’s quality assurance and quality control activities. Each prime Contractor will make their and their subcontractor’s, applicable documentation available to SEPTA. D. Each prime Contractor, and their subcontractors, is required to cooperate fully with testing and inspection activities carried out by SEPTA and its agents. The Contractor will provide the SEPTA PM with adequate (as determined by the SEPTA PM) notification for all activities which require testing and/or inspection.
