The Silesian Hospital in Opava was established at the end of the 19th century and consists of independent pavilions. This will become a thing of the past, as these pavilions will be connected by above-ground corridors. These will connect the inpatient pavilions of the hospital at the level of the first floor, namely pavilions S and V, the next connection of the corridors will be at the connecting neck of pavilions L and N.
We are currently processing production and assembly documentation.
We recently visited the construction site of CROY s.r.o. Mercedes-Benz in Bravantice. This is a newly built area that supports the sale and service of trucks in the Moravian-Silesian region. The skeleton of the entire building is formed by a steel structure. Our assignment was to create production-technical documentation, which we create in the professional software Trimble Tekla (VTD). This is documentation that serves for steel construction suppliers. According to the documentation, the supplier is able to make the appropriate parts for subsequent assembly. An integral part is also the assembly assembly according to which the supplier is able to assemble the structure. As is often the case lately, it wouldn't be a proper project if nothing had to be solved. Before starting the creation of the VTD, we had to design all the connections of the structure in such a way that they only "screwed" during assembly and did not weld. Part of our work is also coordination with other subcontractors so that the construction goes as smoothly as possible. That is why we coordinated with the suppliers the construction readiness for cladding, window fillings, door seals, preparation for air handling units, etc.
We have been cooperating with the company IPS stavební a.s. for some time on a project in the Ostrava area of Dolní Vítkovice (DoV). It is an interesting and no less complex object, which consists primarily of two objects - a tipper and a mill. Our tak was to create a production-technical documentation (VTD) for the newly built floor in the tipper and partly also in the mill. Before starting VTD, we ran into certain pitfalls in the design solution. And this primarily in the anchoring of the longitudinal beams, which were carried by the floor beams themselves. In cooperation with the Hilti CZ company, we performed tensile tests of chemically bonded anchors in order to find out the necessary data for the design of a new anchorage. Another difficult part was to modify the proposed structure for the planned elevator, which was not allowed to disturb the structure of the existing building (monuments). Other structural parts (in which we participated) of the entire site include a newly built connecting neck, railings in the underground, reinforcement documentation for monolithic structures in the tipper. It was nerve wracking, but the result is worth it.
One of our frequent projects is the documentation production for train station structures and traffic solutions.
For the project for the train station revitalization we have created a complete documentation for the roofing of train underpasses and stops with a focus on outdoor durability and seismic resistance. We have incorporated a water drainage system, glass fiber windows, customised sandwich cladding. Our focus was to develop a structure able to withstand every day air gust and transport tremor. We also paid great deal of attention to glass surfaces buffer during underground movement for extra longevity. The documentation is very detailed and solves even the last rivet in the soffit.
Industrial de-dusting has an important impact on environmental protection. It limits the release of harmful substances into the air, which contributes to a sustainable and healthy environment.
The final workshop documentation was issued in parts. The structure is manufactured in Europe and shipped to Brazil in containers. For our business partner we have supplied final workshop documentation of the Flare stack and the supporting structure .
