The effects of construction delays are not confined to the construction industry only but also influence the state of the overall economy of a country. This is particularly so in Thailand where delays seem to be a common problem faced by most construction projects started in the 1987-91 economic boom period. Through a survey of twelve building projects in Bangkok, Thailand, this study identifies the causes of delays experienced by the I concerns. The sources of delays were grouped into two categories: external and internal. On the external sources side, the results indicate that causes of delays are shortages of some resources, government authority and site limitations. On the internal side, it was pointed out that design-originated problems, owner's influences, coordination deficiencies and contractor's management deficiencies are the most important causes of delays. Along with the causes of delays, recommendations are suggested. This study also outlines the ideal conditions for a building construction project. The idea is intended to assist the project participants to identify the possible problem areas which have to be detected and alleviated beforehand to reduce possibility of delays in their project.
