As the construction sector is becoming more competitive in recent years, it has become more important to estimate the duration and cost of the construction projects and to calculate the risks’ effects correctly. The aim of this thesis is to estimate the duration and cost of construction projects accurately using an activity based risk assessment method which is based on the integrated duration – cost influence network diagram model proposed by Tah and Poh (2006). Within the context of this thesis, a web based risk assessment tool using the integrated duration – cost influence network at an activity level is developed to estimate the possible cost overrun and delay in construction projects. Risk breakdown structure for construction projects is created which enables the evaluation of risk effects at an activity level. The developed tool uses Monte Carlo Simulation Technique and Risk Rating Method. The results of the developed tool are compared with those of traditional methods and the reliability of the developed tool is validated.

Developing a strategic information system for construction companies Güneş, Tanyeli; Dikmen Toker, İrem; Department of Civil Engineering (2008) Problems and issues at project level have been the main concern of the construction management studies and construction professionals. Consequently, the long-term strategic issues at corporate level remained uncovered in construction companies. The complex and unique characteristics of the industrial context of construction also limited the adoption of strategic management concepts by the companies. Recently, however, changing business environment, increasing competition in construction arena and higher cli...
A Web based multi user framework for the design and detailing of reinforced concrete frames - beams Anıl, Engin Burak; Kılıç, Özgür; Department of Civil Engineering (2009) Structural design of reinforced concrete structures requires involvement of many engineers who contribute to a single project. During the design process engineers have to exchange wide variety of information. Unmanaged data exchange may result in loss of resources. Developing a data model and setting up protocols for the management of data related to various structural design tasks can help to improve the quality of the structural design. In this study, an object oriented data model was developed for reinfo...
A web based multi-user framework for the design and detailing of reinforced concrete frames-columns Ünal, Gökhan; Kurç, Özgür; Department of Civil Engineering (2009) In design and detailing of a reinforced concrete frame project, there are many engineers who contribute a single project. Wide variety of information is exchanged between these engineers in design and detailing stages. If the coordination between engineers is not performed sufficiently, data exchange may result in loss of important information that may cause inadequate design and detailing of a structure. Thus, a data model developed for different stages of design and detailing of reinforced concrete struct...
A probabilistic schedule delay analysis in construction projects by using fuzzy logic incorporated with relative importance index (RII) method Özdemir, Mustafa; Gündüz, Murat; Department of Civil Engineering (2010) The aim of this thesis is to propose a decision support tool for contractors before the bidding stage to quantify the probability of schedule delay in construction projects by using fuzzy logic incorporated with relative importance index (RII) method. Eighty three (83) different schedule delay factors were identified through detailed literature review and interview with experts from a leading Turkish construction company, then categorized into nine (9) groups and visualized by utilizing Ishikawa (Fish Bone)...
An improved finite grid solution for plates on generalized foundations Karaşin, Abdulhalim; Gülkan, Polat; Department of Civil Engineering (2004) In many engineering structures transmission of vertical or horizontal forces to the foundation is a major challenge. As a first approach to model it may be assumed that the foundation behaves elastically. For generalized foundations the model assumes that at the point of contact between plate and foundation there is not only pressure but also moments caused by interaction between the springs. In this study, the exact stiffness, geometric stiffness and consistent mass matrices of the beam element on two-para...
