Abstract

The construction delay is a main problem in large construction industry of Pakistan. Large construction industry is very important for the development, economy and progress of Pakistan. In research methodology, we conducted a questionnaire survey to get data about the causes of delay and effects of delay. We asked the clients, contractors and constructions by questionnaire and we took interviews of labor to fill questionnaire about causes and effects of delay. To analyze the data, we applied a statistical formula to calculate the RIR value for importance of causes and effects. We used RIR values to rank the causes and effects. Then we discussed the sixteen important causes, five main effects of delay and related the effects with the main relating causes. Later, we described some main large construction projects in Pakistan and the delay affecting these projects. At the end, we suggested some solutions to counter delays by solving or lessening the causes and effects of delays. By these solutions, the delays in Pakistan’s large onstruction industry can be alleviated.
