Petram Resort Savudrija – Foundation Designs
Located at the micro-location Alberi in Savudrija in northwestern Istria, the construction of the Petram Resort is underway. The new resort will offer 252 top-quality properties for holiday or residence. As part of the resort, the construction of an aparthotel and 55 villas with catering, tourism and service facilities is planned.
We have conducted engineering geological and geotechnical investigation and testing and made the geotechnical report and geotechnical projects for construction purposes. Also, we are supervising the execution of works.
The planned foundation of the aparthotel will be carried out in the form of reinforced concrete drilled piles and underpinning to the bedrock. The underpinning of the base plate is executed at the part where the bedrock is at a depth of up to 1.50 m below the level of the bottom of the base plate, and the reinforced concrete piles are at depths greater than 1.50 m.
After the excavation and embankment as part of the formation of working plateaus, the execution of reinforced concrete drilled piles made of concrete with a compressive strength class C30/37 was started. Reinforced concrete piles are made in diameter D = 900.0 mm inside the cover and D = 780.0 mm inside the bedrock with a minimum length within the rock mass of 2.35 m. Concreting of the piles is carried out using the contractor procedure. The piles are reinforced with preformed reinforcement cages.
In addition to the execution of reinforced concrete piles, the excavation for underpinning is carried out. Underpinning is planned with concrete of minimum strength class of C16/20. Rock material is used for filling along with concrete, provided that the volume fraction of rock does not exceed 30%.
To ensure the highest possible reliability and clarity when designing, the foundation of the building is made with BIM.
