Abstract
The desire of acquiring rapid profit and turnover resulted in squeezing construction periods, regardless of the degree of complexity and sophistications of modern construction projects.Squeezed construction periods increase the risk of completing construction projects behind schedule and over budget. The number of delay claims has been increased exponentially as a result of tightening project durations.The analysis of delay claims has become an extremely complex, time‐consuming and costlyprocess. This is because the analysis entails extensive exploring of factual data and a thorough study of the effects of actual events on the progress of works. where delay events are unplanned events that may affect the progress of the work in a manner that actual progress is deviated from planned progress.Despite the existence of a wide range of delay analysis methods such methods suffered from several drawbacks and need to be improved. Most of the existing delay analysis methods are incapable of analyzing concurrent delays, lost productivity and acceleration claims.Meanwhile, they are not in line with the development of advanced planning and scheduling software packages. The lack of uniformity among delay analysis methods can provide widely varying results that complicate the process of settling delay claims.Delay claim analysis employs two basic parts: the first is the entitlement and determination of extension of time and the second is the computation of the financial damages. Most of delay analysis techniques focus on the first part which is the entitlement and determination of the time extension. This is while the second part of the damages calculations is not integrated in most of the analysis. Both parts are equally important. Without entitlement, damages cannot be recovered. Without obtaining damages the mere establishment of entitlement and time extension means that equitable adjustment is not achieved.Extensive research has been conducted on the impact of delays on construction projects.Great efforts were directed to compare between existing methods of delay analysis looking for superiority. Other efforts were directed to improve and automate the existing methods.vi While others tend to develop new models that expedite the delay analysis processes.However, the new proposed models are limited to finish to start relationships and for small and medium size projects.The objective of this thesis is to propose a new automated model for analyzing delay claims using spreadsheets and database. The analysis includes both extensions of time and delay damages calculation based on as‐planned and updated schedules available.The proposed
model will greatly reduce the analysis time as compared to the conventional delay analysis methods and techniques. The proposed model is suitable for small, medium and large size projects.The proposed model validation is performed using two real life projects as a case study. The final results of the proposed model are compared with the actual results of these two real life projects and are identical.These two case studies demonstrate that the proposed model is easy to use, accurate, systematic, speedy and applicable for any type of construction projects that utilizes Critical Path Method (CPM) for developing time schedules. Moreover, this proposed model presents a road map for claimants to settle their delay claims.In addition, a computer model called “Generic Delay Analysis Module – GDAM” was developed to automate the proposed model in a user friendly manner with different interfaces compatible with project planning and scheduling programs. This computer model presents a step forward for further improvement of the model in order to be integrated into commercial planning software packages.
