Brief
This contract involves the modernization and expansion of the heating system in Piaseczno to make it energy-efficient and cost-effective. The project follows a 'turnkey' approach, encompassing all necessary construction works, supplies, and services to ensure that Heating Plant I and Heating Plant II meet required operational characteristics, guaranteed technical parameters, operational capacity, and safety standards, even if certain elements are not explicitly mentioned in the contract. Key components of the project include: 1. Thermal modernization of Heating Plant I. 2. Supply and installation of a cascade system of air-water heat pumps with a capacity of at least 3.5 MW at Heating Plant I, serving as the lower heat source for water-water absorption heat pumps with a capacity of at least 8.5 MW. 3. Construction of Heating Plant II with technical and office facilities. 4. Relocation of two existing gas boilers from Heating Plant I to the new Heating Plant II. 5. Supply and installation of a cogeneration unit with an electrical capacity of 0.999 MW. 6. Installation of a daily heat storage tank with a capacity of 200 GJ. 7. Equipping Heating Plants I and II with photovoltaic systems with a capacity of at least 5 kWp. 8. Gas supply system for Heating Plant II, adapting the existing natural gas management at the Piaseczno facility. 9. Heat output system from Heating Plant II, adapting the existing network water system at Piaseczno. 10. Electrical output system from Heating Plant II to a new 15 kV station, built in coordination with the distribution system operator. 11. Modernization of the control system for Heating Plant I and installation of the control system for Heating Plant II, allowing local and remote control of heat sources (boilers, auxiliary devices, etc.). 12. Measurement and settlement systems compliant with requirements for electricity and heat production from high-efficiency cogeneration and renewable energy sources. 13. Ensuring noise conditions are not worsened in the office part of Heating Plant I and at the property boundaries. Heating Plants I and II will produce heat for the municipal heating network in Piaseczno. Heating Plant I, particularly the existing cogeneration unit along with new heat pumps, will serve as the primary heat source. The contract boundaries are defined as follows: 1. The contract boundaries include external construction objects, technological installations, electrical systems, and AKPiA related to the facility, which are not the contractor's responsibility but must be connected to the heat pump system, thermal modernization, and construction of Heating Plant II. 2. Elements of objects, installations, etc., referred to as contract boundaries, include these elements and their connection to cooperating systems, falling under the scope of supplies, services, and construction works. 3. If any element necessary for the proper operation of the heat pump system or Heating Plant II is omitted in the technical specification, it falls under the contractor's responsibilities. The specified boundaries of construction works, supplies, and services are the contractor's basic obligations. If it becomes necessary to exceed these boundaries during construction to ensure proper operation, the additional works will also be the contractor's responsibility. 4. The scope of the contract includes: Services: a. Conducting ground investigations. b. Design, agreements, obtaining decisions. c. Author supervision. d. Execution of complete devices and equipment. e. Transport of devices and equipment to the construction site. f. Prefabrication, assembly, acceptance tests, commissioning, regulatory operation, trial operation, verification of guaranteed parameters, and handover of the cogeneration unit for operation. g. Training of the client's personnel. h. Providing guarantees regarding the completion time, reliability, and operational parameters of the installation. i. Preparing required documentation and submitting applications on behalf of the client to obtain final usage permits and notify the completion of construction. j. Full geodetic service of the works, including post-construction inventory and submission of an application to the city office for updating building records (if required). k. Appointing a construction manager as per the Construction Law. l. Employing specialists in various fields with necessary gas, electrical, and welding qualifications for specific work fronts. m. Ensuring factory supervision of supplied equipment. n. Obtaining usage permits. o. Obtaining permits for emissions of gases or dust into the air. p. Obtaining a license for electricity generation in high-efficiency cogeneration and changes to the heat generation license. Construction Works: q. Understood as the execution of designs and construction works. Supplies: r. All necessary supplies enabling the realization of the heat pump system, Heating Plant II, and thermal modernization within the specified boundaries. s. Supplies include the initial filling of systems with working fluids. A detailed description of the contract subject is included in Annex 1 – Technical Specification.
