Geotechnical and mineralogical, characteristics of blue-green clays of the Harbour District existing inside the boundaries of Antalya Konyaalti Municipality were investigated with comprehensive field and laboratory tests. Today, building construction in this district is being carried out without any prior qualified geotechnical investigations taking place. Undisturbed and disturbed soil specimens were taken from 12 drilled boreholes at 1.5 in intervals and down 30 in deep. Shelby tubes samples were retrieved and SPT were carried out in order to determine soil profile and geotechnical properties. After comparing the laboratory and field test results, it was observed that they were in agreement. Strength and compressibility characteristics of the soil were defined with the correlations using laboratory and field test results. Since the region has been formed of lagoon-sedimented clays, Rock analyses were done on the two specimens achieved from various depths along the soil profile. XRD analyses on eleven specimens were also conducted. Unconfined compressive strenght (q(u)), undrained cohesion (C(u)) and compression index (C(c)) varies between 40 kN/m(2) and 144.2 kN/m(2), 7.0 kN/m(2) and 90 kN/m(2), 0.095, and 0.38, respectively.
