The Symphony Residential Complex in Varna promises tranquility, exclusivity and a sense of wellbeing among nature. Located within walking distance from the city centre, the beach and the Sea Garden park, the site is located in a popular residential area and offers a panoramic view of the sea. Great emphasis has been placed on living comfort and quality with the floor plan, spacious, sun-lit rooms with a ceiling height of 2.70 m and the construction materials. The main building will be constructed between 2018 and 2021 and will contain 180 apartments over 40,000 m² and a height of 46 m. The ground floor will also contain grocery stores and a cafe. 

“More than 40 different products by our company are being used in various multi-trade applications during the project", says Christian Greicha, Managing Director of the Austrian subsidiary of the fischer Group of Companies. “Our high-quality products and services tailored to the building type as well as the trust in our partnership were decisive for being awarded the contract”. Angel Bratanov, Regional Head of Sales for East Bulgaria at fischer Austria, added: “We supported our client as early on as during the planning and technical implementation stage through drawings, calculations and pull-out tests. We will continue to provide support until the project’s successful completion”. 

System and fixing solutions for various applications 
UltraCut FBS II concrete screws and FIS SB 585 S injection mortars with system components for temporary and permanent fastening tasks were used to erect the supporting structure made of C30/C37 concrete. The modern building envelope made of glass as well as ceramic and aluminum compound cladding has already been completed and provides a distinguished look. The substructure system for the ceramic panels of the rear-ventilated facade was anchored using SXRL frame fixings and UltraCut FBS II concrete screws in the anchor base made of concrete and Poroton bricks. DHM insulation supports together with FTM 80 insulation discs were used to fasten the insulation panels behind the facade cladding and the rear-ventilated zone. The drill holes were created in concrete and hollow bricks using the Quattric II hammer drill. UltraCut FBS II concrete screws were also used to secure the wall brackets for the glass facade’s carrier profiles. Additional steel and chemical fischer heavy-duty fixings secure sun protection and air conditioning facilities to the facade. 

Products of fischer also cover electrical fittings and building services. The FLS channel systems and SXRL frame fixings fasten the supporting structure to lay the cables and electrical wires. Building service applications were also carried out with fischer installation and fixing systems. The FLS and FUS channel systems fasten the media lines. Channels and ALK cantilever arms are the corresponding base elements that were installed together with system components such as FRS and FGRS pipe clamps and threaded rods. 
fischer FireStop solutions seal duct openings of MEP applications (mechanical, electrical and plumbing) as well as construction joints. Products used also included our FiAM fire wall. When this 1-component water-based acrylic emulsion is exposed to fire it forms a highly insulating barrier through which the product guarantees a physical barrier for up to 5 hours. The intumescent 1-K FiGM mass was also among the products used and is based on a graphite material that expands up to 20 times its own volume under high pressure. The product subsequently hardens into an elastic and flexible fire sealant. The elastomeric fire-resistant coating FFB-ES and a foam gun were also used to seal the construction joints.
