    Brief

    This contract involves a framework agreement for construction and installation works aimed at enhancing energy efficiency in 12 buildings owned by the Bulgarian Academy of Sciences (BAS) located in Sofia. The project is divided into two lots: Lot 1 focuses on energy efficiency improvements for 11 buildings, while Lot 2 includes similar improvements and conservation-restoration works for the National Museum of Natural History. The contract is categorized as construction work, and the framework agreement will be established with up to six potential contractors for Lot 1 and three for Lot 2. If there are not enough qualified bidders, the agreement may still be signed with fewer contractors. Each specific contract will be awarded through an internal competitive selection process, detailing the scope and timeline of the work. The construction activities will include energy efficiency measures such as replacing windows, insulating walls and roofs, upgrading heating systems, and ensuring fire safety and accessibility for people with disabilities. All buildings involved are classified as third-category constructions under Bulgarian law.
