Exploring Causes of Delay in Payment from Parties involved in Road and Highway Projects in Thailand.

Delay in payment is considered to be one of the most periodically arisen problems in the construction industry. It harms time, cost, and quality. This paper presented a result of a survey which investigated causes of delay in payment of road and highway construction projects in Thailand. Parties involved in construction-borne failure identified the causes of delay in payment and their severity through a questionnaire survey. The delay in payment causes were categorized into 4 main groups (owner, contractor, consultant and architect) which was based on parties-borne failure. The questionnaire listed of 41 factors and sought to identify the significance of major delay in payment factors and determine their impact on road and highway construction projects. The total of 120 responders was asked to weight the degree on seriousness via a questionnaire survey. The survey concluded that top five severity indexes in causing a delay in payment were delays in progress payment, the financial status of owners, poor qualification of the contractors' technical staff, delays in issue approval documents and failure in applying for claims.
