I. Project Name: Minhai Biotechnology New‑Type Vaccine International Industrial Base Construction Project II. Project Overview: The Minhai Biotechnology New‑Type Vaccine International Industrial Base Construction Project, invested and developed by Beijing Minhai Biotechnology Co., Ltd., is located on parcels 0503‑039, 040, 043, and 044 within the Daxing District Biopharmaceutical Industry Base. The project’s boundaries are as follows: to the north, Simiao Road; to the south, the planned land‑use boundary (municipal green space); to the west, Xiangrui Avenue; and to the east, Tianfu Avenue. This project is primarily intended for the research, development, and production of human vaccines. The total site area is 90,013.218 m², designated as M1 Class I industrial land. The total floor area amounts to 189,820.11 m², with a building height of 33.3 meters, comprising one underground level and eight aboveground floors. The construction includes the following facilities: No. 1 R&D Pilot Workshop, No. 2 R&D Technology Workshop, No. 3 Comprehensive Service Building, No. 4 Laboratory Animal Facility, No. 5 Hazardous Waste and Dangerous Goods Storage, No. 6 Wastewater Treatment Station, No. 7 Boiler Room, No. 8 Vaccine Production Building, No. 9 Packaging and Warehousing Building, No. 10 Bacterial Vaccine Production Building, No. 12 Basement, No. 13 Gatehouse and Carport, No. 14 Gatehouse, and No. 15 Gatehouse. The main substation for the entire facility—whose cable distribution room is located inside the No. 9 Packaging and Warehousing Building—is equipped to handle a total plant‑wide load exceeding 12,000 kW. Seven distribution rooms are distributed across the aboveground buildings and underground spaces. III. Scope of Tender: This tender covers the electrical design for both the external power supply and the internal distribution system of the new base project, constituting a primary power‑supply system design tender. The external power‑supply works extend from the connection point specified in the power company‑approved installation plan to the high‑voltage switchgear section of the cable distribution room within the new base. The internal distribution system design encompasses the portion from the high‑voltage outgoing terminals at the distribution room to the low‑voltage outgoing terminals at the substation. Key design drawings include, but are not limited to: External Power Supply Works: cable trench construction drawings, cable routing diagrams, grounding system construction drawings, substation equipment foundation plans, substation layout plans, primary electrical system diagrams, secondary wiring diagrams, cable tray layouts, high‑voltage terminal diagrams, cable schedules, back‑end monitoring systems, and electrical fire‑alarm monitoring systems. Internal Distribution System Works: cable conduit burial plans, cable routing diagrams, grounding system construction drawings, substation equipment foundation plans, substation layout plans, primary electrical system diagrams, cable tray layouts, cable schedules, back‑end monitoring systems, and electrical fire‑alarm monitoring systems. IV. Design Requirements: All designs must comply with the following national and local regulations and standards: - GB 50217‑2018 “Code for Design of Power Cables” - GB 50169‑2018 “Code for Construction and Acceptance of Grounding Systems in Electrical Installations” - GB 50053‑2013 “Design Code for Substations up to 20 kV” - GB 50052‑2009 “Design Code for Power Supply and Distribution Systems” - GB 50054‑2009 “Design Code for Low‑Voltage Distribution Systems” - GB 50057‑2010 “Design Code for Lightning Protection of Buildings” - GB 50229‑2019 “Fire‑Protection Design Code for Thermal Power Plants and Substations” - GB 50116‑2013 “Design Code for Automatic Fire Alarm Systems” - DL/T 5221‑2016 “Technical Specifications for Urban Power Cable Line Design” - DLGJ 154‑2000 “Design and Construction/Acceptance Standards for Cable Fire‑Protection Measures” - Typical Design for Distribution Rooms issued by State Grid Beijing Electric Power Company. V. Relevant Requirements: 1. Timeframe: Complete the power company’s review procedures for the design drawings by December 31, 2020. 2. Contractor Responsibilities: Handle all installation and power‑supply scheme procedures—including those involving the Municipal Power Bureau, the Daxing District Power Bureau, and relevant authorities—and bear all associated costs. 3. All design content must conform to current national standards and meet all requirements for product grid‑connection certification set by the Beijing Power Department, ensuring smooth acceptance by the power bureau and successful commissioning. VI. Registration Guidelines: 1. Participating entities must submit electronic copies of their business license, qualification certificates, safety production permits, legal representative identification or corporate authorization letter, and personal ID cards. Please also indicate the registered capital of your company; supporting documentation of similar project experience may be provided concurrently. 2. Applicants must possess appropriate professional design qualifications. 3. Provide contact information for a designated representative, who should serve as the project manager or authorized liaison, along with proof of social insurance coverage for the past 12 months. 4. The tenderer will review submitted qualification documents, giving priority to applicants with comparable project experience, and will conduct further discussions and site inspections with shortlisted candidates. 5. Beijing Minhai Biotechnology Co., Ltd. was established in 2004 and is a wholly owned subsidiary of Shenzhen Kangtai Biological Products Co., Ltd. (a publicly listed company).
