Abstract: The structure of the diploma project consist of five sections: architectural and constructional, calculational and constructional, technological and organizational, construction economics and science section. According to the assignment for the diploma designing it is necessary to make a project: The project of a 14-story residential building "Four Sides" in Lviv city". The harmful effects of the projected building on the environment are absent. The building is designed from traditional materials, with the partial introduction of new, safe for the inhabitants and nature materials. The construction will not pollute the environment. The level of groundwater goes deeply, so water will not be polluted neither. Flat surface and greenery are maximally preserved, the minimum volume of land works, soil reclamation are provided. Improvement of the territory provides areas for planting deciduous trees, shrubs and lawns by sowing perennial grasses. Structural scheme of the building - with load-bearing reinforced concrete columns. The rigidity is provided by a joint work of columns and a monolithic overlap (horizontal diaphragms of rigidity), the presence of a staircase that forms a geometrically invariable system. Before the foundation, a crushed stone pillow are arranged. The foundation of the building is a reinforced concrete slab with a thickness of 1 m. For the foundation, concrete of class C20 / 25 is used. The reinforcement of the foundations contains reinforcement grids of the reinforcement class A500C. The walls, acting as an enclosing structure, are made of D600 foam blocks - 600x300x200 mm, the wall thickness is 300 mm, and to ensure standard heat losses, the insulation - polystyrene foam with a thickness of 50 mm - is attached with dowels, and the insulation is covered with external plaster 20 mm thick with subsequent painting. Internal walls with a thickness of 300 mm are made of foam concrete. Internal design partitions - 150 mm, material - plasterboard. Ruberoid is used as a vapor barrier (for the waterproofing of the foundations –vertical and horizontal, and for the installation of the roof). For outdoor flooring of living rooms and bedrooms we use laminate. For floors of corridors, kitchens and bathrooms we accept ceramic tile on a cement-sand solution. The overlapings are made of monolithic ferroconcrete with the thickness of 200 mm. The armature A500S, concrete of a class C20 / 25 are used. The overlaping rests on the load-bearing columns. The coating is made of wooden frame, on which the metal skull plates are attached. Drainage of water from the roof is made with drainage gutters, passing outside the house.The windows are made with reinforced plastic by the "VEKA" company, the doors – also of reinforced plastic. Above the windows and doors unified prefabricated ferroconcrete bearing bridges are designed. Stairs - monolithic reinforced concrete consist of marches and platforms. The stair surface must be sheathed with laminate. In calculational and constructional section such constructions has been calculated: - the foundation; - the first floor overlap; - the roof construction. -the reinforced concrete column The calculations of the building are executed in 2 ways: automatically - program "Lira", and manually. The technological map is designed for the installation of an overlap plate of first floor. The technological map reflects the amount of work on the various stages of the overlap the corresponding technological schemes of armature grids layout on the object, schedules of work, guidance on the slab installation, slab quality requirements, calculations of the need of machines and workers, specification of equipment, main means, fixtures and tools, solutions that provide security processes and organization of work, technical and economic performance. The effectiveness of concrete and ferroconcrete works depends on the technological level of each individual process, and on the degree of coherence of their implementation. The erection of monolithic ferroconcrete structures is a labor-intensive process. A calendar schedule for the construction of this building, a schedule for the movement of machines and mechanisms, a schedule for the needs of workers, and technical and economic indicators were also developed. A construction master plan was also developed - it shows the state of the construction site during construction, placement of temporary buildings, temporary roads and communications. In the fourth section a local and summary estimate costs for my building was made. Local estimate cost is the table which specify how much it cost to do particular building or installing process including the paychecks for workers and the cost of materials. So basically, we have got an amount of money that cost to build such building object. In the scientific section, I investigated the use of composite reinforcement for column reinforcement, compared it with conventional reinforcement, and drew conclusions.
