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, delay analyst, and delay analysis methodology. The main purposes of this study are to identify the shortcomings frequently encountered in the implementation of delay analysis applications in all stages of a construction project, to address the responsible element, and to propose a set of rules to overcome these shortcomings and obtain accurate and reliable results. For this purpose, 17 shortcomings were identified. Moreover, an integrated approach is developed which is composed of a set of rules solving all of the identified shortcomings, and a flowchart guiding the parties from scratch until the end of the project. This study is unique in its nature as it encompasses all stages of a construction project that contribute to a delay analysis application. (C) 2014 American Society of Civil Engineers.

Exploring the Relationship between Complexity and Risk in Megaconstruction Projects Erol, Huseyin; Dikmen, Irem; Atasoy Özcan, Güzide; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2020-12-01) © 2020 American Society of Civil Engineers.Although complexity and risk are inherent characteristics of megaconstruction projects, existing project management approaches fail to incorporate complexity-based thinking into risk management. Complexity is usually considered as the source of risk events, along with uncertainty. However, prevailing risk management practices are oriented toward only handling the uncertainty. The lack of integration between the complexity and other risk-related concepts leads to un...
Contextual Information Requirements of Cost Estimators from Past Construction Projects Kiziltas, Semiha; Akinci, Burcu (American Society of Civil Engineers (ASCE), 2009-09-01) Past project data sources provide key information for construction cost estimators. Previous research studies show that relying only on one's own experience during estimation results in estimators' bias. Having and referring to historical databases, containing objective information on what happened in past projects, are essential for reducing estimators' biases. The first step toward development of useful project history databases is to understand what information estimators require from past projects. The ...
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...
Neural Network Model to Support International Market Entry Decisions Dikmen Toker, İrem; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2004-02-01) Bidding for international construction projects is a critical decision for companies that aim to position themselves in the global construction market. Determination of attractive projects and markets where the competitive advantage of a company is high requires extensive environmental scanning, forecasting, and learning from the experience of competitors in international markets. In this paper, a neuronet model has been developed as a decision support tool that can classify international projects with resp...
Delay Risk Assessment of Repetitive Construction Projects Using Line-of-Balance Scheduling and Monte Carlo Simulation Tokdemir, Onur Behzat; Dikmen Toker, İrem (American Society of Civil Engineers (ASCE), 2019-02-01) Although the line-of-balance (LOB) method is widely used for the scheduling of repetitive construction projects, there are only a limited number of studies that deal with the issue of how to incorporate uncertainty in repetitive schedules. In this paper, a delay risk assessment method is proposed for projects scheduled by LOB. In the proposed method, a LOB schedule is prepared considering the target rate of delivery, and then risk scenarios are defined considering the sources of uncertainty and vulnerabilit...
