ABSTRACT
The High Rise Building Construction projects have a complexity of the work and a complex structural design that cause the large possibility of technical risk. It is crucial to do a technical risk assessment analysis for the classification of technical risk and how to handle it. The purpose of this research was to identify technical risks and risk responses to high category technical risk in the Grand Sungkono Lagoon project, Surabaya. The identifications were done by conducting a validated literature study with a preliminary survey. This research used a fuzzy logic method to assess the process of technical risk and it was assisted with MATLAB 2015a application by distributing the main questionnaire to selected respondents. From the result of the analysis, there were 7 high-level technical risk variables which consist of the effect of weather on the implementation, the difficulty mounting formwork and scaffolding at altitude, the existence of design changes, re-work, unsuitable system planning, poor equipment maintenance and wrong implementation methods.
