Many factors such as unforeseeable events, managerial or financial problems of Contractor, insufficient technical capacity of Engineer's site team and so on may lead to delays in construction projects. Proper analysis of compensability and quantum of a delay event is very important. Any delay analysis application can be considered as a result of the combination of contract documents, scheduler, record keeping mechanism at site, communication among project participants, delay analyst and delay analysis methodology. The main purpose of this study is to analyze the shortcomings frequently encountered in implementation of delay analysis applications and propose an integrated solution which synthesizes the solution methods for each. For this purpose seventeen (17) shortcomings were identified and solution methods were suggested for each. Moreover, these shortcomings were attributed to the previously identified elements of delay analysis applications such as contract documents, scheduler etc. Furthermore, an integrated approach is developed which synthesizes the suggested solution methods at different stages of delay analysis applications in order to obtain accurate and reliable results. In order to test the validity of the proposed integrated approach on a real project, a resource and cost loaded construction schedule with approximately four thousand (4000) activities is created by using Primavera software which is currently being used to monitor "Construction of One Reception Center and One Removal Center Project in Erzurum". In the case study, the necessary events are created in order to be able to compare the results of the proposed integrated approach and the likely result of erroneous delay analysis applications. It was apparently figured out that the proposed integrated approach has yielded accurate and reliable results and a comparison table was prepared showing the difference between the results of the proposed integrated approach and the likely result of an erroneous application.

Integrated Approach to Overcome Shortcomings in Current Delay Analysis Practices Birgönül, Mustafa Talat; Dikmen Toker, İrem (American Society of Civil Engineers (ASCE), 2015-04-01) Many factors, such as unforeseeable events, managerial and financial problems of contractors, insufficient technical capacity of site teams of contractors or Consultants, and so on, may lead to delays in construction projects. Proper analysis of compensability and quantum of a delay event is of prime importance. Any delay analysis application can be considered as a result of the combination of contract documents, scheduler, record-keeping mechanism at the site, communication among project participants, dela...
A Hybrid genetic algorithm for multi mode resource constrained scheduling problem for large size projects Gürel, Mustafa; Sönmez, Rifat; Department of Civil Engineering (2015) Just like in all industries, some of the available resources, in order to finish a project on time, are constrained in construction industry. To be able to finish the project on time has high importance both for the contractor and for the owner. Project scheduling in which resources are limited for a particular time are called as resource constrained project scheduling problems (RCPSP) and occupies a significant place in construction management. Especially for large scale projects, little success has been a...
Identifying the barriers of implementing lean construction principals in developing countries Markazi Movaghar, Ehsan; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2016) The construction industry is congested with many types of project management systems to control and manage construction projects but none of them really look in-depth to maximize the efficiency of the work flow and minimizing waste. The implementation of the lean construction principles into the local construction scene can improve the problems. However, lean construction is complex and can be risky if not properly managed. Lean construction efforts in some other countries have not been successful due to th...
Identifying the effects of lean construction principles on variability of project duration / Erol, Hacı Hüseyin; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Department of Civil Engineering (2014) Performance of the construction projects have been criticized for many years due to their low productivity rates and cost overruns as well as significant delays. Increasing number of dissatisfied customers compel practitioners to reform conventional practices of construction management. Lean construction emerges as a result of change efforts in the industry. Lean construction promises a much better project performance by eliminating the waste and improving value to customer. Although many practical applicat...
An ontology-based approach for delay analysis Bilgin, Gözde; Birgönül, Mustafa Talat; Dikmen Toker, İrem; Department of Civil Engineering (2011) Delay is a common problem of construction sector. Recent improvements in the sector increased the competition and this led the construction projects to be more complex than before and difficult to be completed in time. This situation not only increased the delay problems, but also made the analysis of delays difficult and that caused further problems as disputes between parties to the contract. Sound knowledge in delay analysis subject is needed to enhance the solution of the delay problem in construction p...
