Struttura temporanea di stoccaggio e officine di fabbricazione (EPC) - Progetto AP1000 in Polonia

1. Experienced and qualified Companies are invited to provide engineering and construction services, including supply, installation, testing and commissioning of Temporary Warehousing Structure and Fabrication Shops (commodity code UA11) at the project location for the Poland Nuclear Power Plant. The facilities are industrial standard, temporary, non-safety related, non-seismic, commercial-grade steel buildings, intended solely to support construction activities and not plant operations. All works must comply with Polish law, EU standards, and Authority Having Jurisdiction (AHJ) requirements, with the Pomeranian Voivode acting as AHJ. General Building Characteristics: - Structures are steel-framed, modular or pre-engineered metal buildings (PEMB). - Buildings are single-story, rectangular, low-rise, with pitched roofs. - Facilities must remain fully operational year-round in a Baltic coastal environment for a design life of 15 years. - All buildings are electric-only; no gas installations are permitted. - Uniform construction technology, finishes, and systems must be applied across all buildings for each of two types of buildings: warehouses and fabrication shops. - All furnish and production lines are excluded from the scope, the subject of the bid is limited to the solely buildings only. Temporary Warehousing Buildings - Quantity and Size 3 temporary warehouse buildings, total area 22,170 m²: - Warehouse 182: 8,400 m² (120 × 70 × 10 m) - Warehouse 183: 7,650 m² (150 × 51 × 10 m) - Warehouse 184: 6,120 m² (120 × 51 × 10 m) Structural and Architectural Requirements - Reinforced concrete slab foundations designed for heavy material handling. - Steel superstructure enclosed with insulated metal wall and roof panels. - Fire-resistant construction materials. - Concrete floor finish throughout. - Light-colored exterior siding and roofing. Functional Requirements - Areas for receiving, unpacking, sorting, staging, and “on-hold” materials. - Segregated storage for tools, instruments, piping, electrical materials, and hazardous goods. - Pallet racking, shelving, bins, and forklift-compatible aisle spacing. - Rapid roll-up material doors (minimum 6 m clearance). - Minimum four personnel/emergency exits per building. - Climate control (heating, ventilation, and cooling where required). - Access control via card, mobile app, or biometric systems. - Adequate drainage, lighting, and proximity to work fronts. - Overhead crane in the warehouse No. 184 Temporary Fabrication Shops - Quantity and Size 11 fabrication buildings, total area 20,735 m². Each building: 1,885 m² (65 × 29 × 10 m). Structural and Architectural Requirements - Reinforced concrete slab foundations. - Commercial-grade steel superstructure. - Insulated metal siding and roofing. - Fully enclosed, climate-controlled environments. - Ventilated. Functional Requirements - Fabrication lines and material handling areas. - Tool and equipment storage with secure access. - Rapid roll-up material doors and personnel exits. - Fire-resistant materials and systems. - HVAC systems. - Adequate site drainage and lighting. - Layout flexibility subject to Buyer approval. Building Systems and Installations (Applicable to All Buildings) Structural - Designed for dead, live, wind, snow loads. - Anchored steel structures on reinforced concrete slabs. Mechanical (HVAC) - Air handling units with heating, cooling, filtration, and heat recovery. - Dedicated ventilation systems for warehouses and workshops. - Electric-powered systems only. - No permanent water or sewage systems; portable handwash stations only. Fire Protection - Fire classification per Polish regulations (ZL I or as determined). - Fire alarm system. - Emergency lighting. - Internal hydrants (25 mm), fire extinguishers, fire dampers. - External hydrants with 20 dm³/s water flow. - Fire access roads and rescue provisions. Electrical - 400/230 V, 50 Hz TN-S earthing system. - Main distribution panels and sub-panels. - LED lighting (normal and emergency). - Emergency lighting minimum 90 minutes autonomy. - IP54-rated electrical enclosures. - Lightning protection per PN-EN 62305. Design, Permits, and Compliance - Seller responsible for full design, engineering, and coordination. - Final Design must be sealed by licensed Polish engineers/architects. - Compliance with Polish law, EU directives, and project specifications is mandatory. The detailed scope of work will be outlined in the specifications, scope documents, and other contractual materials provided to the Companies within the Request of Quotation.
