Geotechnical investigation and testing – Albatros 2 Hotel, Cavtat
The construction of a new Albatros 2 Hotel building is planned on a plot of about 50 thousand square meters near the town of Cavtat. The future building for catering and tourism purposes will cover 16.400,88 square meters and have a total of 3 above-ground and 1 underground floor with a total of 252 accommodation units.
For the construction purpose geotechnical and engineering geological investigation and testing were carried out. The works included geological and geotechnical prospection of the wider area, excavation of probing pits, concrete strength tests, exploratory drilling, standard penetration tests, engineering geological mapping of the terrain and determination of drilling cores and boreholes, geophysical surveys and laboratory testing of samples from boreholes.
In the scope of the geotechnical investigation and testing, four rotary boreholes (individual lengths of 12.0 to 15.5 m and total length of 55.0 m) were drilled. Also, geophysical tests of shallow seismic refraction of P-waves (Delta-t-V-method) with a total length of 993 m were also conducted.
After the geotechnical investigation and testing, recommendations for the foundation soil arrangement and foundations were established. A shallow foundation with a combination of AB slab foundations and strip foundations on a rock embankment in geotechnical unit 1 – Alluvium was selected.
