The construction industry relies on the successful execution of what is planned. Project cost, schedule, and other performance criteria are set and written on a contract, by which all parties are obligated to abide. Similarly, corporate processes are defined by the procedures of companies. However, projects and corporate processes suffer from various obstacles in practice, some of which arise from certain events that might seem insignificant, causing significant deviations from the plan. These obstacles are quality issues that should be handled by preventing them and correcting the existing ones. The thesis addresses this need by providing a quality management (QM) strategy based on knowledge management (KM). Two research questions search for a systemic approach to prevent inadequate quality and correct nonconformities with KM. After showing the relationship between QM and KM, the research builds an information retrieval mechanism based on the cosine similarity metric and a natural language processing (NLP) model called FastText. The development process is divided into two. The first part enables the effective use of what was previously learned, and the second module deals with correction recommendations in the case of nonconformity. Overall, the study enables the recording, storing, and reusing of tacit information to build a continuous learning and continuous improvement cycle. Processing the information in internal audit findings and lessons learned documents with an NLP model, it is argued that nonconformities can be both fixed and prevented. Ultimately, the thesis aims at a state of zero mistakes in construction through continuous learning and continuous improvement.

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...
DEVELOPMENT OF AN ACTIVITY-BASED LESSONS LEARNED PROCESS MODEL AND A TOOL TO SUPPORT SCHEDULING DECISIONS IN CONSTRUCTION FIRMS Yılmaz, Anıl; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Department of Civil Engineering (2021-11) 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 knowle...
Integrated Approach to Overcome Shortcomings in Current Delay Analysis Practices Birgönül, Mustafa Talat; Dikmen Toker, İrem (American Society of Civil Engineers (ASCE), 2015-04-01) 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, dela...
Improving sub-contractor selection process in construction projects: Web-based sub-contractor evaluation system (WEBSES) Arslan, Gokhan; Kivrak, Serkan; Birgönül, Mustafa Talat; Dikmen Toker, İrem (Elsevier BV, 2008-05-01) One of the most important phases in the construction industry (CI) is the bidding process. During the bidding process, selecting the most appropriate sub-contractors (SCs) for the relevant sub-works is highly critical for the overall project performance. In order to select the most appropriate SCs for the project and prepare the most realistic and accurate bid proposal, general contractors (GCs) have to know all financial, technical and general information about these SCs. Within this context, GCs should co...
Cash flow analysis of construction projects using fuzzy set theory Melik, Serhat; Sönmez, Rifat; Department of Civil Engineering (2010) Construction industry is a one of the most risky sectors due to high level of uncertainties included in the nature of the construction projects. Although there are many reasons, the deficiency of cash is one of the main factors threatening the success of the construction projects and causing business failures. Therefore, an appropriate cash planning technique is necessary for adequate cost control and efficient cash management while considering the risks and uncertainties of the construction projects. The m...
