Factors Affecting the Productivity of the Construction Industry in Thailand: The Foremen's Perception

Abstract

Factors affecting construction productivity in Thailand were disclosed in previous studies carried out by the authors, which confirmed that the construction industry in Thailand has experienced problems like many other countries. The objectives of this paper are to ascertain foremen's perception of factors affecting construction productivity in Thailand and to confirm the results obtained from earlier research on the same aspects. To do so, 57 foremen working in the construction industry in Thailand completed a structured questionnaire survey. The factors were ranked by the use of a relative important index (RII) and results indicate that the six factors that were rated to have more than a moderate effect on productivity in Thailand are lack of material, incomplete drawings, lack of tools and equipment, rework, change order and tools and equipment breakdown.
