Abstract

The building comprised three 70-storey towers constructed over a mat foundation supported on 399 piles in Bangkok. Design incorporated 11 boreholes, 5 CPTu tests, an instrumented static load test on a trial pile, 5 dynamic load tests, and numerous iterations between the structural engineer and the geotechnical engineer. 15 vibrating wire strain gauges were incorporated into the tops of piles when they were connected to the mat. These strain gauges were monitored and settlements of the mat foundation were surveyed until about 12 months after the towers were topped out. The paper presents the design and the monitoring results, together with a numerical analysis for comparison.
