“…There are many delay analysis methods found in the literature [1,[17][18][19][20]. The famous methods include: Global Impact Technique, Net Impact Technique, Adjusted As-built CPM Technique, As-planned Expanded Technique (What-if Technique, As-planned Plus Delay Technique), But-for Technique (As-built Collapsing Technique, Collapsed As-built Technique, But-for Analysis Using As-planned CPM), Snapshot Technique, Time Impact Technique (Modified As-built Method), Windows Technique (Contemporaneous Period Analysis), Modified Windows Approach and Isolated Delay Type Technique.…”

“…The program generated the as-planned, as-built, projected, adjusted, owner-accountable and contractor-accountable schedules based on general project appraisal information. [5] used one delay analysis methodology, the isolated delay type technique, and integrated some commercial software packages of project management system, database, spreadsheets, word processors, and expert system to develop a well functioning system for delay claim analysis. Based on the knowledge-based techniques, Aoude (1996) [6] developed a computer program to assist in identifying and quantifying delays encountered in construction projects.…”

When the completion of a project is delayed, how to accurately analyze the impact of a delayed activity on the project is a main problem for construction project managers. Available professional scheduling tools have been widely employed to plan and control construction schedules. They are not designated for delay analysis that requires numerous computation scenarios by different views. Therefore, a comprehensive management information system (MIS) for schedule delay analysis is needed for schedule delay management. The first step of developing an MIS is to carry out the task of system requirement analysis. This study used the method of IDEFØ, a structured analysis and design technique, to portray the contents of an MIS for schedule delay analysis. Based on the results of this study, further system implementation will be easy to do. Furthermore, the research results can also be used to necessary examination for delay claim preparations.

A decision support framework for extension of time claims for the JBCC Principal Building Agreement

Delays to contractors' progress, often resulting in time and cost overruns, are a major source of claims and disputes in the construction industry. The assessment of extension of time (EOT) claims as part of a construction project can have far-reaching consequences for the financial success of the project. The proper and transparent assessment of EOT claims is, therefore, an essential component in the success of any project. In this article, an actionresearch approach, a very specific qualitative approach, was followed to develop a userfriendly guideline to help practitioners navigate this potential minefield of complexities in the process of the assessment of EOT claims. Focus groups, consisting of industry practitioners, with specialist knowledge in construction contracts, contributed to the development of the decisionsupport frameworks, and ultimately to the findings. The iterative process followed assisted in producing a tool that can be used in practice as a guideline for the analysis of EOT claims when using the Principal Building Agreement of the Joint Building Contracts Committee (JBCC).

“…The question of causation concerns the need for a claimant to prove not only that a risk allocated to the other party occurred but also that it caused the delay complained of. The third category has been aimed at development of Information and Communication Technology (ICT) support tools such as knowledge-based systems (Raid et al 1991;Diekmann and Kim 1992) and other decision support systems (Bubbers and Christian 1992;Mazerolle and Alkass 1993;Yates 1993;Battikha and Alkass 1994;Alkass et al 1995;Lucas 2002;Oliveros and Fayek 2005). Finally, there have been surveys into aspects of some of the existing methodologies (Bordoli and Baldwin 1998;Harris and Scott 2001;Kumaraswamy and Yogeswaran 2003).…”

Delayed completion of a construction project is often caused by a complex interaction of a combination of events some of which are the contractor's risks while others are the project owner's. The apportionment of the liability to give effect to the risk allocation has therefore been a matter of great controversy. Many delay analysis methodologies have been developed over the years for performing this task. This paper reports on an empirical study into the current practice in the use of these methodologies in the United Kingdom, as part of a wider study aimed at developing a framework for improving delay claims analysis. The part of the study reported here was based on a questionnaire survey of key informants. The issues investigated include the categories of staff within contracting organizations who contribute to delay claims analyses, the awareness, use and reliability of existing delay analysis methods and the obstacles to their use in practice. The main findings of the study are that: (i) the preparation of delay claims often requires input from commercial managers (quantity surveyors), schedulers, site managers, external claim consultants and estimators; (ii) commercial managers have the greatest involvement; (iii) claims analyzed using the As-Built vs. As-Planned and the Impacted As-Planned techniques are often successful although there is considerable literature on the shortcomings of these techniques; (iv) The main obstacles to the use of the methods relates to deficiencies in project records and scheduling practice.
