Implementation of construction and installation works for the implementation of energy efficiency measures in an administrative building (Former District People’s Council) in the town of Kardzhali, Financing Contract for the provision of funds to final recipients of the Recovery and Resilience Facility (RRF/MECHANISMA), Investment (SRI) No BG-RRP-4.020 ‘Support for sustainable energy renovation of public buildings for administrative services, culture and sport’, No in the IS of the RRF BG-RRP-4.020-0264-C01. The full and detailed description of the specific types of works relevant to the site in this award are reflected in the technical documentation prepared – investment project (phase – technical design), with explanatory notes and drawings attached, annex to the documentation for participation in the procedure. The implementation of the main types of works envisaged shall be carried out in compliance with the requirements for construction works under Article 169(1) of the Spatial Planning Act, on the basis of a technical design. Wherever the notice or this documentation refers to a make, source, process, trade mark, patent, type, origin or production, it shall read ‘or equivalent’. All construction materials must meet the requirements of the current Bulgarian state standards, the requirements of the investment project, BDS, EN or, if imported, be approved for use on the territory of the Republic of Bulgaria and have a quality meeting the warranty conditions. Execution with non-standard materials is not allowed. TECHNICAL INDICATORS Built-up area – 1 515.72 m2 Total built-up area under the Spatial Development Act – 4 512.47 m2 projects envisage the following renovation measures: • Thermal insulation of external walls On all facade walls, thermal insulation from EPS with a thickness of 12 cm and a coefficient of thermal conductivity λ≤0,035 W/(m.K) will be performed. The reversal of the windows will be performed with thermal insulation of extruded polystyrene (XPS) with a thickness of 2 cm and a coefficient of thermal conductivity λ≤0,033W/(m.K). On the thermal insulation is laid putty with glass textile mesh. Corner profiles and water-dropping profiles are laid at the corners. The final coating is silicate plaster. • Balcony and terrace railings • Roof insulation • Roof repair • Floor insulation • Replacement of windows and doors • Accessibility solutions - According to Article 2(1) of Ordinance No RD-02-20-2 of 26 January 2021 laying down the requirements for accessibility and universal design of the elements of the accessible environment in the urbanized territory and of buildings and facilities, the existing elements of the accessible environment are brought into line with the requirements of the Ordinance, in their reconstructions and major renovations. In this regard, the draft treats the requirements of the ordinance only to the elements in which there will be intervention. At the entrances of the building are available landings with dimensions larger than 150/80 cm / Art. 46, para.2, item 3 /. The eastern entrance of the building is located on the ground level. This is the accessible entrance to the building. The front door is replaced with a new, two-leafed one, with a light width of the active wing 90 cm (Article 49(3)). To overcome the differential steps at the accessible entrance, it is planned to install a staircase hoist with a moving platform with a size of 70/120 cm. To overcome the different levels of the building, it is envisaged to install stair lifts with a moving platform of 70/120 cm at the two main staircases in the building . The construction of the building is reinforced concrete, monolithic, skeleton-beam. It is built of reinforced concrete beams and slabs, bearing brick walls and a wooden roof. According to the norms in force during construction, the walls are located in 3-4 m in plan, mutually perpendicular. The walls are framed with reinforced concrete belts and beams. An orthogonal network of beams and belts covering the whole building in both directions has been developed. The walls in the basement are 65 cm thick and in the upper part are as follows: External - 45 cm; Internal load-bearers - 45 cm, 30 cm; Internal non-bearing -15 cm. The walls are made of dense bricks of lime-cement solution. THE USE OF CONCRETE CLASS C20/25 WITH WATER CONSTRUCTION CW 0.6 (equivalent to B25 CW 0.6) - AIR CONCRETE SUITABLE FOR EXTERNAL CONSTRUCTIONS EXPOSED ON AIR IMPACTS IS REQUIRED. IMPLEMENTATION OF PHOTOVOLTAIC ELECTROCENTRAL - On the roof structure are located: - 144 photovoltaic panels with a total weight of 3 916.80 kg; - Mounting and fastening profiles, with a total weight of 360 kg; - Cables, cable trays, etc., with a total weight of 223.20 kg. The total additional weight on the roof structure is 4,500 kg. The cargo is spread over an area of 375 m2. Installation of photovoltaic panels is carried out by means of metal clamps and profiles mounted on mineral wool pads. The clamps, profiles and pads of mineral wool have a reaction to fire class A1, in order to ensure high fire resistance of the system. The solution aims to prevent direct contact between the metal elements and the wooden structure, while limiting the formation of thermal bridges and increasing the durability of the installation. The obligation of the builder is the elaboration, updating and placement of accessible and prominent places in the respective work area of safety and health instructions. The main parameters of the construction, dimensions, materials, design scheme are indicated in the explanatory notes and these should be considered together with the graphic part. The contractor must carry out the envisaged types of activities in strict compliance with the investment project - graphical and textual part. Detailed information on the scope and content of the types of works can be found in the Technical Specification, the investment project, incl. the explanatory notes prepared by the authors of the project. An inseparable annex to the specification is the QUANTITY ACCOUNT and the INVESTMENT PROJECT.
