Description of execution
Another industrial project we had the pleasure of realising at the end of last year was the construction of a distribution centre in the Dolnośląskie province. The building had a surface area of 70,000 m².
Production process of prestressed roof girders
For the project, we produced and delivered:
- 363 columns,
- 232 prestressed girders, up to a height of 2 m,
- 1143 prestressed purlins,
- 168 beams, up to 1.5 m high,
- 403 walls, with an area of: 2.85×6.5 m,
- 210 single-layer base walls,
- 182 docks
- 56 retaining walls,
- 24 stair flights,
- over 3 m² of prestressed hollow core units.
The ordering party set ambitious requirements for us regarding the comprehensive delivery of the structure, including assembly and detailed design.
The design part consisted of the execution of detailed designs for the investment and workshop drawings of individual elements – that is almost 1,000 drawings. The design provided for the optimisation of the building's structure, among others by reducing the structural height of the roof, which resulted in an increase in the usable height for storage.
The prefabricated elements for this project were produced in our 4 plants – around 800 elements per month. The prefabricated elements varied in terms of geometry and cross-sections, which required the preparation of a large number of moulds in a short period of time.
The bar elements, including columns, beams and roof girders, were really large prefabricated elements: over 20 metres long and weighing up to 50 tonnes. Specialised vehicles with low-loaders and extensions were used to transport them to the construction site. Unusual transport was also used to transport the prefabricated walls of the refrigerated part of the building. They were transported in special inloader self-loading semi-trailers, in which the floor is only a few centimetres above the ground. Thanks to this solution, we were able to manufacture 2.85 m high fire walls, which resulted in a reduction in the number of wall joints on the construction site.
At the peak of the project, we had 5 assembly teams working on the construction site, installing 350-400 prefabricated elements of various types per week. The experience of our management staff and the exemplary partnership with the General Contractor allowed us to complete the order on time.
