The project in five facts.
Challenge, approach and results.
Based on his work placement experience throughout his entire period, which includes considerable expertise, he focused in his diploma thesis on researching geological composition and determining the foundation of structures and foundation soil remediation. He thoroughly researched and compared two structures of similar or almost identical shopping centres. In his calculations of costs and quantities, he found that complete replacement of foundation soil terrain is senseless, as deep foundation construction is approximately 43% cheaper and also faster in terms of time. In the second part, he compared the construction of deep foundations at the CP Ravne shopping centre and the construction of minimal foundation soil remediation at Slovenj Gradec shopping centre.
Problem
Based on his work placement experience throughout his entire period, which includes considerable expertise, he focused in his diploma thesis on researching geological composition and determining the foundation of structures and foundation soil remediation.
Solution and Method
He thoroughly researched and compared two structures of similar or almost identical shopping centres. They differed only in that the CP Ravne shopping centre had only a partial basement with shop storage spaces on the ground floor, whilst Slovenj Gradec shopping centre has partial shop storage spaces in the basement and has two stairwells and a lift, which the CP Ravne shopping centre does not have. The structures stand on completely different foundation soils; at the CP Ravne shopping centre structure, deep foundations with bored reinforced concrete piles of 100 cm diameter were required, whilst at the Slovenj Gradec shopping centre, the terrain with minimal remediation beneath the foundations and with the garage basement traffic slab was sufficiently load-bearing for shallow foundation construction.
As a possibility of replacing different construction methods, he researched and studied in individual chapters the possibilities of replacing the entire foundation soil terrain at the CP Ravne shopping centre structure, the possibility of replacing reinforced concrete bored piles with driven micro ductile piles at the CP Ravne shopping centre structure. During his research, he also compared different construction methods in terms of cost, economy and time in individual chapters. He studied and compared the cost and economic justification of replacing the entire foundation soil terrain with constructed reinforced concrete bored piles at the CP Ravne shopping centre structure.
For his research, he used data on actually constructed works (reinforced concrete bored piles) and a geological-geotechnical report for calculations of quantities for complete replacement of foundation soil terrain.
Results
In his calculations of costs and quantities, he found that complete replacement of foundation soil terrain is senseless, as deep foundation construction is approximately 43% cheaper and also faster in terms of time. In the second part, he compared the construction of deep foundations at the CP Ravne shopping centre structure and the construction of minimal foundation soil remediation at Slovenj Gradec shopping centre. Through calculations, he researched and proved that the geological composition of foundation soils is more favourable and that the structure is built at a more rational location in terms of cost justification.
He proved that for a structure on such favourable foundation soils, preparation of foundation soils can be up to five times cheaper if deep foundations are not required. In the third part, he compared and described the possibility of replacing reinforced concrete bored piles with driven micro ductile piles at the CP Ravne shopping centre structure. Based on data obtained from static load-bearing capacity calculations and the geological-geotechnical report and construction, he determined the required number of piles of equal lengths as the constructed reinforced concrete bored piles.
The load-bearing capacity of the pile was distributed to an equal value of 7543 kN. Based on the calculation, they found that 5.89 pieces are needed for one reinforced concrete bored pile and that construction would be made more expensive by 38%, but in terms of time of construction it would be accelerated by approximately 40% compared to the construction of bored piles.
