Tenders are invited for Electrical System Upgrades and Repairs. Closing Date: Sunday, 26. Jan 2025 Intervention Sector(s): Infrastructure & Services Rehabilitation Michel Daher Social Foundation (MDSF), established in 2014, is a Lebanese NGO dedicated to addressing the unique challenges faced by communities in Central Bekaa. Committed to creating an environment where individuals can achieve their highest potential, the foundation focuses on community health care, economic and human capacity building, sustainable community development, and livelihood. MDSFs mission is rooted in providing support to help people overcome life challenges and make a positive impact on the Bekaa community. Project Overview: The project aims to increase access to safe and reliable water services among communities in Zahle Caza, Lebanon, with a focus on improving the capacities of the Bekaa Water Establishment (BWE) and enhancing water services for upstream and downstream communities of Jdita. The project includes technical and material capacity strengthening, community engagement, facilitation of allocation agreements, and activation of the regional water network. Scope of Work Electrical System Upgrades and Repairs Repair all loose and damaged connections in electrical panel boards and components, including MCCBs, MTS, and pump panel boards. (BoQ will be identified after site inspection) - Replace existing cable lugs, cable glands, shrink tubes, nuts, bolts, washers, cable ties, and all relevant accessories with new ones as required, determined during inspection. Add high-standard 4x240mm² power cables (approximately 13.5 meters) in parallel to: -The main power cable (feeder) between the transformer and the Mains MCCB. - The power cable between the Mains MCCB and the MTS. - Include 16 x 240mm² cable lugs for the installation. Load Balancing and Cable Upgrades Redistribute the loads of the station to ensure similar loads across all phases. Replace torsade cables connecting the 6mm² PV cables (approximately 5,400 meters) from the mountainside PV array to the DC panel board. - Install fuse/fuse holders at the mountainside to connect the existing 6mm² PV cables to the new ones. - Ensure proper and safe installation of fuse/fuse holders while maintaining system integrity. Upgrade the output wiring of the DC panel board to the VFD with a 10mm² PV cable (30 meters estimated). Replace the old DC system with a new, high-grade standard that includes: - 42 DC fuse/fuse holders (20A). - 21 SPD 1KV. - A large DC panel board for the facility. - A waterproof, high-quality, durable panel board for fuse/fuse holders. System Protection and Safety Measures Install a proper NC disconnect emergency switch (e.g., Schneider) for the electrical equipment of the station. - Use a 2x2.5mm² control cable, with the location to be decided during work. Close all electrical enclosures to mitigate hazards. Fix the loose MTS panel board and its junctions to the wall to prevent hazards. Enclose all exposed electrical cables: - Inside the facility using cable covers/boxes. - Outside the facility using a concrete channel. Panel Board and Circuit Enhancements Replace the existing DC panel board circuit breakers with industrial-grade switches: - 21 DC disconnect switches (32A). Install high-grade components for the DC system, including: - Fuse/fuse holders. - SPDs. - New, durable panel boards. Solar System Maintenance Inspect and clean all solar panels across the facility, including: - The mountainside PV array. - The roof of the main building. - The roof of the small building. Relocate the two solar panels connected to the SOROTEC inverter from the mountainside to the main building roof. - Properly reconnect the solar panels to the SOROTEC inverter.
