GIS CONCRETE PLANT
GIS International Group has its own plant and production facilities. Currently GIS Concrete works with reinforced concrete products and metal Structures deals primarily in the production and sale of building materials and structures. The company’s success is assured through a comprehensive level of expertise at all stages of production: from developing new product types based on market requirements, right up to delivery of products to the end user.
The factory is prepared to consider any request to manufacture and supply products on the basis of mutually beneficial terms. Further more, it guarantees completion deadlines and the high quality and reliability of its products.
GIS has developed and introduced a factory-ready, rapid-assembly construction system known as BSS.GIS, which facilitates construction in short timescales and with minimal effort. To date, we’ve built 69 buildings via this method. The structures in the BSS.GIS series are designed for the construction of social/cultural/leisure and residential sites in different climatic zones, including the Far North and regions with high seismicity (up to 9 points on the Richter scale). These structures have a number of advantages over traditional designs, including:
- Flexible layout.
- Accelerated building assembly.
- Non-labor intensive.
- No “wet” processes to affect the structural rigidity of the building during assembly.
- Low specific weight of the design.
The assembled elements of the building are made of reinforced concrete. Building assembly is undertaken in sections, with each section comprised of two external bi-modular wall panels that join together with rigid frame joints at the floor or ceiling panels. Buildings are from 6.0m-to-15m wide, with a 3.0m step, and are 4 stories high. Designs are currently under development for 6-, 8- and 10-story buildings. Single-story buildings can be 3.3m, 4.8m and 6.55m high. The BSS.GIS designs have no standardized length, and the maximum width of a single-bay industrial construction is 12m, with possible blocking of additional bays.
The industrial buildings’ own support structures enable the installation of hoist mechanisms of up to 5 tons. Where it is necessary to equip these buildings with mechanisms of a higher carrying capacity, additional supporting devices can be mounted.
The external wall panel fascias are detailed with patterned border-relief elements, giving the facades an original architectural appearance. Where necessary, the facade elements of the panels can be painted, faced with traditional surfaces (facing bricks), or faced with different modern finishing materials.
BSS.GIS designs correspond with new heat engineering requirements. They also meet level II fire resistance, and are certified by Gosstroy of Russia (? ???? RU. ??48.?00094, ? 0169405). Fire resistance could easily be raised to level I, when glassfoam heat insulation is applied.
BSS.GIS designs have proven themselves, especially in the building of camp settlements for construction workers and operatives in the oil and gas sector. Many sites have now been built under GIS projects.

In accordance with the decision of All-Russian Research Institute for Fire Protection of the Ministry of Internal Affairs (VNIIPO), support structures must have a 2-hour fire resistance, corresponding with level II under State Standard (SNIP) 21-01-97.
The main component of the buildings is a reinforced concrete three-layer panel (see Fig.1). This panel is 3m wide and 6.55m high for two-story buildings, and 3.3m wide and 4.8m high for single-story buildings, with bearing edges. Polystyrene (1) is used as heat insulation, with thermal conductivity of l = 0.04W/m °? and with a thickness of 150-to-200mm, dependent upon the climatic region. The external 30-mm thick coating layer is made of reinforced high-density concrete (2).
At the edges of the panel, the polystyrene is protected from inflaming by a mineral wool cord (3), and cement-sand mix or cement-shaving slabs (4). The packing of vertical joints between panels has a high quality hermetic seal, due to the installation of packing bundles made from Vilatherm (5), foamed polyurethane (7) and the bolted coupling (6) of panels during assembly.
Panels are made of reinforced concrete ribbed plates. The design of their hydro-thermal insulation and reinforcement depends on the load and the intended use. Floor slabs (8) are inserted from one side into the wedge-like grooves of the wall panels (9) using two skew corbels. In the base of these skew corbels is a metal “knife” part (10). A design of this kind ensures a high degree of reliability of the connections (Fig.2).
