| Popis: | 102 In Road and Bridge construction projects, delay could be defined as the time overrun either beyond completion date specified in a contract, or beyond the date that the parties agreed upon for delivery of a project. It is a project slipping over its planned schedule and is considered as common problem in construction projects. To the owner, delay means loss of revenue through lack of production facilities and rent-able space or a dependence on present facilities. In some cases, to the contractor, delay means higher overhead costs because of longer work period, higher material costs through inflation, and due to labor cost increases. Completing projects on time is an indicator of efficiency, but the construction process is subject to many variables and unpredictable factors, which result from many sources. These sources include the performance of parties, resources availability, environmental conditions, involvement of other parties, and contractual relations. However, it rarely happen that a project is completed within the specified time. The main purpose of this study is to identify the delay factors on road and bridge projects completion. A questionaire survey was conducted to solicit the causes of delay from clients, consultants, and contractors. This study indentified 5 most important causes of delay from a list of 39 different causes of delay. Five most important causes were: Slow land acquisition, Price fluctuation, Delay in progress payment by Owner, Poor site management &; supervision by Contractor, Financial difficulties of Contractor. Finally, some solutions dealing with project delay problems in construction executing stages are proposed |
