Due to the need for organizing the production line in a way that allows for its modification at any time during the plant’s operation, without the need for significant construction work, the production hall along with the office part (expansion) is planned as a unified, double-nave structure consisting of prefabricated elements. The supporting columns are designed as reinforced concrete, prefabricated, anchored to foundation footings. Prefabricated reinforced concrete beams (prestressed concrete) will be placed on the columns to provide the required span (without intermediate supports). The floor is planned as a reinforced concrete slab, allowing for the flexible arrangement of equipment.
The office part is designed (depending on the variant) as an additional floor located above the production area (variants 1 and 3) or as part of the production in the second nave of the expansion (western part, variant 2). In two variants (1 and 3), a second floor is designed, analogous to the existing building. Individually constructed will be the part in the immediate vicinity of the overhead power line, due to the irregular plan of the proposed expansion (imposed by the aforementioned line). However, the construction of this part will also be based on prefabricated elements, predominantly reinforced concrete.
The double-nave hall in the production part allows for the organization of space and the placement of equipment in a way that ensures their potential mobility or the possibility of adjusting their positioning. Skylights will complement the production part of the hall, improving workplace lighting and ensuring proper distribution and penetration of natural light. The entire building will be finished with layered aluminum or steel sheets coated with paints. The glazing is designed as column-and-beam, aluminum façades, reminiscent of the existing building.
The maximum scope of expansion, limited on the western side by the plot boundary, on the northern and northeastern sides by the overhead power line, on the eastern side by a public road and existing internal communication, and on the southern side by the existing production-office building, forced non-standard communication solutions. An additional challenge is the low clearance of the overhead power line crossing the plot, preventing the use of the internal road by heavy vehicles in the current situation. The project envisions the distribution of functions at different levels (height levels) to utilize the natural slope of the terrain, limiting expenses related to leveling the floor height of the expanded and existing parts and enabling the location of an extensive maneuvering area with parking spaces directly under the power line. Lowering the floor of the warehouse section allows for a safe distance for trucks from the installation overhang. Variant 1 assumes the location of production with a medium clear height of h=8m on the maximum possible built-up area. Additionally, above production, an extra floor with mixed functions, production-office-facility (height h=5m in the clear) is planned, and the warehouse is located beneath the production area (with a height of h=4.5m). Variant 2 assumes production with the maximum possible clear height of h=12m, similarly, a warehouse with a clear height of h=10.5m. The entire complex is complemented by a lower part with mixed functions (clear height h=8m). The entire plan is designed on one level, as a single-story building with varying heights and a warehouse floor set below the production floor and the floor of the existing building. Variant 3 assumes a warehouse as in the variant above, production with a clear height of h=8m, and an additional floor located above production (with a clear height of h=5m).
