New materials, developments in technology, increasing need for new buildings and changing requirements has dictated a large variety of new construction techniques. According to specific conditions of each project, global new industrialized construction techniques or local traditional construction techniques or combinations of them all are used in erecting "the building". The use of different kinds of construction techniques in combination on a single project creates a complex and sometimes irrational situation. For improving or rationalizing construction techniques the current situation needs to be determined. In the study construction techniques used in projects under local environmental conditions of Istanbul Turkey are investigated. In the study 55 different construction phases of architectural components, in 16 different construction sites, were observed. Analyses were done in the context of operations in the construction process, location of construction and the construction inputs, namely; materials, tools and labour force. Results of the analyses are presented.
