DEVELOPMENT OF AN ACTIVITY-BASED LESSONS LEARNED PROCESS MODEL AND A TOOL TO SUPPORT SCHEDULING DECISIONS IN CONSTRUCTION FIRMS

2021-11
Yılmaz, Anıl
The construction industry still suffers from reaching critical objectives of projects like duration and budget. To deal with this situation researchers and practitioners realized the importance of knowledge management in the construction industry and put their increasing attention on it over the years. Especially, knowledge management utilization in planning and scheduling parts of construction management has made significant efforts to improve to meet projects objectives adequately. However, project knowledge capture and reuse in different projects have remained a major challenge for the construction industry. For this purpose, this study aims to introduce an activity-based lessons learned process model to integrate previous projects’ lessons learned into scheduling to enhance consistency and accuracy in forthcoming projects’ schedules. In this respect, the process model has been developed according to the requirements in literature review and needs analysis with construction industry experts. Then, the developed process model was evaluated by construction management professionals. A tool (ConSALL) corresponding to the process model has been implemented. A case project is demonstrated on the tool (ConSALL) and verified by experts from the construction industry. Findings show that the developed process model and the tool (ConSALL) have the potential to integrate lessons learned into the construction schedules to increase efficiency in durations estimation in future projects.

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 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, ...
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...
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 ...
Development of a knowledge-based risk mapping tool for International Construction Projects
Yıldız, Açelya Ecem; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Department of Civil Engineering (2012)
Due to its high-risk nature, international construction projects are more vulnerable to adverse changes in project environment and company objectives. To achieve successful project outcomes, early provision of risks has a vital place in managing construction projects. Within the literature, several risk assessment methodologies have been offered to simulate probable consequences of risks. The majority of the proposed methodologies are limited in reflection of real project conditions as they require probabil...
