An assessment model: The efficiency of consultants when dealing with delays in construction projects in Libya

The consultant plays an important role in monitoring and checking project time schedules and protecting the owner from any claims -which are the most problematic tasks. There is no existing scale with which to determine the consultant's efficiency, therefore developing an assessment technique is crucial. This research has been conducted by obtaining opinions from a field survey of Libyan experts in construction project supervision during the execution phase. The main objective is to develop a model to assess consultant's efficiency relating to construction projects delays. By applying this model to Libyan consultants, their level of efficiency can be measured. This model will also help the owner in selecting a consultant organization, and will help the consultant to improve their human resource management and professional development.
