The compatibility of estimated schedules with real conditions is crucial for the planning and management of construction projects. Several research studies confirm that inaccurate schedules impose a considerable amount of cost and delay to the projects. One of the key reasons is the assumption of constant productivity of crews regardless of the projects’ unique physical conditions. Therefore, there is a need of calculating project-based and preferably dynamic productivity values for construction activities. In recent years, 4D BIM has been increasingly utilized to improve construction productivity by providing a clearer view of the construction methods to managers. However, in general, the visual aspects of 4D BIM have been more in attention. In this work, a new concept is proposed by using 4D BIM and a visual programming language to revise the assumed productivity of the activities. The method exploits the elements’ geometric information including their positions, adjacent elements, and quantities from a BIM model and assigns them to the elements as parameters to be used in the schedule. The concept is implemented on a case project to appraise the capability of being able to revise productivity values based on simulated job conditions. It is predicted that the revised productivity can improve the initial estimations’ reliability and accuracy.

A Fuzzy delay assessment tool for construction projects Ghaziani, Aydin; Dikmen Toker, İrem; Birgönül, M Talat; Department of Civil Engineering (2012) It is a known fact that construction projects do not often complete on time due to several reasons related with the unexpected changes in the project conditions, external factors or performance of project participants. Since construction projects are unique and limited information is available at the beginning of the projects, prediction of delays is a difficult task. However, if the delays can be assessed at the early stages, their impacts might be minimized, some of the delays can even be eliminated. This...
A Mixed integer programming method for integrated discrete time-cost trade-off and manpower resource leveling problem Tatar, Ali Can; Sönmez, Rifat; Atan, S. Tankut; Department of Civil Engineering (2016) Construction projects have to meet all of the objectives of scope, quality, schedule, budget simultaneously. These objectives, however, cannot be considered as independent of each other. For example, an increase in direct resources will usually lead to shorter activity durations. A shorter project duration results in lower indirect costs, whereas the additional resources cause an increase the project’s direct costs, in general. This phenomenon is defined as time-cost trade-off problem (TCTP). Nevertheless, ...
An Integrated regression-bootstrap sampling scheduling method for probabilistic duration range estimation of construction projects Barış, Özgür; Sönmez, Rifat; Department of Civil Engineering (2019) The estimation of project duration is important in construction projects, since it directly affects the costs and the success of the projects. Schedule risks can be determined along with the duration estimations in order to assess the possibility of delay penalties and additional costs. Therefore, the accuracy of the estimation of project duration range is very crucial in construction industry to assess the schedule risks. This thesis presents an integrated approach of non-parametric bootstrap sampling meth...
BIM EXECUTION PROCESS OF CONSTRUCTION COMPANIES FOR BUILDING PROJECTS GERÇEK, Bilge; Tokdemir, Onur Behzat; İLAL, MUSTAFA EMRE; GÜNAYDIN, HÜSNÜ MURAT (2017-07-29) Building Information Modeling (BIM) has been an emerging concept in architecture, engineering and construction (AEC) industry with a vast amount of promising benefits to construction projects. Implementation of BIM, however, requires comprehensive research and strategic planning. Industry-wide and organizational implementation guidelines and standards have been published around the world either to encourage organizations to adopt BIM or to present the minimum requirements to be followed where BIM implementa...
MEASURING THE IMPACT OF LEAN CONSTRUCTION PRACTICES ON PROJECT DURATION AND VARIABILITY: A SIMULATION-BASED STUDY ON RESIDENTIAL BUILDINGS Erol, Huseyin; Dikmen Toker, İrem; Birgönül, Mustafa Talat (2017-01-01) 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 has emerged as a result of these efforts in the industry. However, there are limited number of studies that demonstrate the practical benefits of lean construction applications. The aim of this paper is to ...
