CLAIMS IN CONSTRUCTION PROJECTS “DESIGN ERRORS AND CHANGE ORDERS”ER

In the implementation of a construction project, there are many difficulties and unexpected problems in the design phase. In some cases these problems are caused by design and sometimes consulting engineer or supervisor depends on diligence in solving these problems by changing the orders issued to the Contractor simple limited or large comprehensive. In both cases, these problems date back to the engineer or related with him and usually it leads to the claims of contractor's, material or time, or both , in turn, leads to an increase in the cost of the project and its duration for the owner of the project. This study aims to know the types of claims that occur in construction projects because of mis-design that goes back to the General Engineer. This study is based on a sample statistic, random, for projects implemented in Libya during the last ten years and it has been the monitoring of claims and their impact on the project, which resulted mainly from design errors and change orders that were later during implementation, define this search the causes of claims and types which are generally related to engineer, through a sample of these projects, and then concludes that a number the results can be taken to avoid occurrence of such claims in the future.
