The project in five facts.
Challenge, approach and results.
Initially, he addressed the history of concrete in the diploma thesis, specifically how it began to be used, why it is most suitable, and actually began to determine what the future brings us and why the future lies with prefabricated elements. He researched which are the most common prefabricated concrete elements on the market at present, namely: prestressed roof elements, prestressed hollow floors, floor elements, T-T floor elements, hollow wall elements, solid concrete wall elements and sandwich wall elements. The emphasis of the research was based primarily on the comparison of costs, construction time and carbon footprint of sandwich concrete walls and floor slabs. He found that according to the basic calculation of bare costs, prefabricated concrete walls are approximately.
Problem
Initially, he addressed the history of concrete in the diploma thesis, specifically how it began to be used, why it is most suitable, and actually began to determine what the future brings us and why the future lies with prefabricated elements. He researched which are the most common prefabricated concrete elements on the market at present, namely: prestressed roof elements, prestressed hollow floors, floor elements, T-T floor elements, hollow wall elements, solid concrete wall elements and sandwich wall elements.
In the continuation of the diploma thesis, he focused on a concrete case from practice, namely a multi-residential building constructed by Gradnje Lenart d. o. o. in Lenart on Jurovski cesti 14.
Solution and Method
The emphasis of the research was based primarily on the comparison of costs, construction time and carbon footprint of sandwich concrete walls and floor slabs.
Results
He found that according to the basic calculation of bare costs, prefabricated concrete walls are approximately 20% more expensive, whilst concrete floor elements are approximately 15–20% cheaper, naturally without considering the time aspect of building construction and the reduction in labour force, which are significantly in favour of prefabricated elements, which additionally reduces construction costs. The carbon footprint of prefabricated elements is lower than that of conventionally constructed concrete structures due to less manipulation of formwork elements, labour force and transport of materials to the construction site.
Based on these data, we can conclude that the cost of prefabricated construction compared to conventional construction is approximately the same, and in some cases even cheaper. Naturally, certain mechanisation is required for this construction (mobile crane, crane, etc.), as well as additional staff qualifications, which in practice does not present a major problem, as we can actually save on labour force (which is known to be in short supply on the market anyway), and additional construction mechanisation is also required for larger projects with conventional construction, such as a specific lift.
The future, in his opinion, therefore belongs to prefabricated elements, which are increasingly coming to the fore and are being used more and more by construction contractors. However, the exception is not only concrete elements, as we see more and more CLT – cross-laminated timber, frames and similar products on the market, which additionally simplify or accelerate the construction process compared to the conventional method.
