Sockets with the required degree of safety will be used, depending on the area and location of installation. 4. Water supply and sewerage systems: 4.1. Water supply system – The water supply scheme includes water supply systems for cold, hot and circulation water for daily use and drinking, as well as water supply system for industrial purposes for the garages within the building. Polypropylene pipes with the required cross section and water-supply fixtures will be used, based on the applicable calculations – CK and OK, with additional metal layer for the hot and circulation water polypropylene pipes. The water supply installations in the garage area will be mounted in an open configuration on the walls and ceilings, using brackets and thermal insulation. Thermal insulation material will be used for all pipes mounted on exterior walls. The fire hydrant pipes will be made of 2-inch zinc-coated pipes with standing Fire Hydrant-2 units on each floor. The fire hydrant will be equipped with 20 m hoses with 13 mm nozzles. 4.2. Sewerage system – Gravitational sewerage system will be installed in the building. Household and storm sewage (from the roof, terraces and the yard) will be discharged out of the building via the already constructed sewerage branch (SSB) made of robust PVC pipes with diameter of 200 mm. The sewage from the building will be discharged into the urban mixed sewer (along the Rakovski Street). The household sewage will be discharged through vertical 110 mm PVC pipes down to elevation +0,30 situated within the communications shafts. Revision sections (110 mm) will provide access to the sewerage system. Ventilation flaps (110 mm) mounted to all vertical pipes will ensure the ventilation of the sewerage system. The fixtures and equipment in the sanitary units will comply with the Bulgarian State Standard (BDS). In the sanitary units there will be 50 mm bell traps with lateral drainage opening. Two 110 mm collector funnels on the roof of the office building will be used to convey the storm water to the downtake pipes (110 mm down to elevation +0,30). Lateral drainage traps (100 mm and 110 mm) on the terraces will convey the storm water to elevation +3,40. Revisions units (110 mm) for access to the drainage systems will be constructed where necessary. The condensate from the ventilation convectors mounted on each floor will be drained through 25 mm drainage pipes and siphon connections linked, where practical, to the vertical sewerage pipes or dedicated vertical pipes down to elevation +0,30. 5. COMMUNICATION AND SECURITY SYSTEMS 5.1 Structural cabling system: A complete structural cabling system complying with the TIA/ EIA standard has been constructed in the building.

The whole building (from level +3.45 to level +24.00) will accommodate 328 workplaces. The Layer 2 and Layer 3 devices are of the highest Cisco class. The MDF will accommodate the Cisco Catalyst 2811 router, the optical switch Cisco 3750, and 3 Cisco Catalyst 2960 (24-port) commutators. Each of the other IDFs will accommodate one Catalyst 2960. Thus, having set up a complete backbone and designated V-LANs, the communication means of the other systems – video surveillance, BMS - will be fully operational as soon as the first phase of the construction of the building is completed. 5.2 Video surveillance system The video surveillance system is based on IP technology and has megapixel quality. It covers the perimeter of the building and the common areas. The system includes 36 cameras and can be further expanded. The control and recording server is situated in MDF and, depending on the level of authorization, it can transmit video signals and information to each node of the network. This system allows further integration in accordance with the specific needs of the user. 5.3 Fire alarm system The Fire alarm system covers the entire building and is based on addressable fire alarm network. In case of fire, it communicates with the other systems (HVAC and access control) to allow safe evacuation from the building, if necessary. The system uses graphic display and allows further integration in accordance with the user’s needs. 5.4 Access control system The access control system is based on noncontact cards and tags, and covers the technical areas, offices, emergency exits, and the load elevator – ramp. The elevator can be operated from a distance of up to 15 m. In addition to the controlled access to certain zones, the system can also be used for other purposes as well – working time and attendance control, easy export of data to ERP systems. 5.5 Security alarm system The security alarm system is based on modular configuration and covers all office floors. Each office floor can be divided into groups, and, using the LCD keyboard, each group can be individually included or excluded from the area currently covered by the security alarm system. 5.6 BMS The main purpose of BMS is to manage and control the operating expenses in the building. The current consumption of electric power, heat and water on each floor can be monitored online. The system displays information about the actual consumption for the time being or for any specified period of time. 5.7 Measurement – individual measuring devices with consumption optimisation functions – heat/cold measuring unit, water meter; electric meter. 6. SHOPS Most of the finishing works and installations will be similar to those in the office areas. The differences in the installations were described above, while the specific finishing works will be as follows: 1. Glass partition walls – window displays – The plasterboard partition walls will be combined with 10 mm single-layer glass walls and aluminum frames. 2.
