An ontology-based approach for delay analysis

Bilgin, Gözde
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 projects. So, this study aims to share knowledge in delay analysis issue by construction of a delay analysis ontology that provides direct and comprehensive knowledge. The constructed ontology may ease the information sharing process and provide a base for the usage of information in computers for different purposes especially in risk and claim management processes. It may enable companies to create their own knowledge bases and decision support systems that may achieve improvement in the knowledge and its usability. To meet this objective, detailed literature review on delay subject is carried out and an ontology on delay analysis issue is created. The created ontology is validated through its comparison with three different case studies.


Development of an IT-based tool for portfolio assessment and management for construction companies
Bilgin, Gözde; Dikmen Toker, İrem; Özorhon Orakçal, Beliz; Department of Civil Engineering (2019)
Development in the construction industry has leaded most of the construction companies to undertake more complex projects than before, which are generally executed concurrently. Therefore, project management routines of the companies may not support effective management of multi-projects. Project portfolio management approach has been suggested to meet requirements for coordinating multi-projects to meet strategic objectives under limited resources. Since project portfolio management requires a comprehensiv...
A Construction Delay Analysis Approach Based on Lean Principles
EROL, HACI HÜSEYİN; Dikmen Toker, İrem; Birgönül, Mustafa Talat (2017-07-12)
Delay is a quite common problem for construction projects. The existing practice of construction management is usually based on assessment of delays, liabilities and claims. However, this approach does not serve to remove the underlying causes of delay problems. In addition to estimation of delays, there is a need for a systematic method that will prevent delays in projects. Lean construction has tools and techniques that can serve for this purpose. However, a formal delay analysis procedure does not exist ...
An ontology-based approach for delay analysis in construction
Bilgin, Gozde; Dikmen Toker, İrem; Birgönül, Mustafa Talat (2018-02-01)
Delay is a common problem of the construction sector and it is one of the major reasons of claims between project participants. Systematic and reliable delay analysis is critical for successful management of claims. In this study, a delay analysis ontology is proposed that may facilitate development of databases, information sharing as well as retrieval for delay analysis within construction companies. A detailed literature review on construction delays has been carried out during the development of the ont...
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...
A Comparative study on direct analysis method and effective length method in one-story semi-rigid frames
Bektaş, Şinasi; Birgönül, Mustafa Talat; Department of Civil Engineering (2012)
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 metho...
