“…The company is ISO 9001-certified since 2009, which requires the use of standardized routines to manage the quality as part of its processes, including but not limited to the quality of the products and services it provides. Design Science Research (DSR) [33] was the approach used to develop the study, in which the gained knowledge is used to develop valid and reliable solutions to solve problems, create, change, or improve existing solutions; and to generate new knowledge, insights, and theoretical explanations. Therefore, this work developed and adapted instruments to collect and organize data and proposed a method (artifact) to address the problem of assessing and ranking the impact of construction defects [34].…”

Evaluating the impact of defects in buildings and ranking the most impactful ones enables construction companies to better choose which paths to take in light of continuous improvement activities to support more sustainable decisions regarding the design and operation of buildings. As a result, the risks of the different choices are more clearly identified while assessing all tangible and intangible aspects of residential building defects in a structured way. Although recent studies on managing construction defects in residential buildings have focused on monetary losses associated with maintenance activities based on the defect’s frequency and severity, these studies do not take into account the levels of customer satisfaction. To address this gap, this paper proposes a novel evaluation method of the impact of defects to support decision-making in managing defect occurrences in residential buildings. The goal is to rank the defects’ impact based on a combination of some critical aspects: frequency of occurrence, financial considerations on repairing such defects, the impact that these defects have on customer satisfaction, and the cost and complexity of preventing and minimizing these defect occurrences through continuous improvement activities. The method consists of a structured set of steps that use data from technical assistance departments and customer satisfaction surveys, where information about the users’ level of satisfaction and the occurrence of defects is available. In this paper, data obtained from a construction company were used to test and validate the proposed method. The method also examines the challenges and barriers associated with the technique and points out that difficulties in acquiring reliable data are a bottleneck for making conscious and sustainable decisions to address construciton defects. Moreover, the case study results highlight essential capabilities needed by companies to correctly assess the impact of defects, such as correctly logging data in a structured database and having skilled personnel to verify defects users might have complained about. The paper ends by proposing a set of guidelines to use the method and stressing that structured methods for decision-making are crucial to analyze construction defects in a structured way while also incorporating the user’s perspective. The proposed method is expected to improve sustainable managerial decisions where economic, environmental, social, and technical risks can be accounted for to enhance the quality of projects from the customer’s perspective. Such analysis can help optimize and prioritize the use of resources and minimize the economic impact of activities on the construction company.

“…In the lean world, the LPS for planning and control (Javanmardi et al, 2018, Salazar et al, 2018, Torp et al, 2018, Kim and Ballard, 2010, choosing by advantages (CBA) - (Nguyen et al, 2009), Virtual First-Run Study (Nguyen et al, 2009), Language Action Perspective (Salazar et al, 2018) and BIM (Aslesen et al, 2018) have been widely applied to support planning, control and decision making. The works by Cortes et al (2018) present some interesting perspectives in Multi Criteria Decision Making (MCDM) using CBA in delivering project benefits. However, there doesn't appear any evidence of accounting for uncertainty in the application of the tools.…”

Many projects continue to fail to deliver intended benefits amid uncertainty in benefits realisation (BR) programs. This is more so in Front End Design (FED) where processes remain not only understudied but also informal yet reliant on knowledge sharing. As a result, there is an emergent need for new decision support tools to support benefits delivery processes. The paper addresses uncertainty with FED processes as a way of facilitating decision making as an enabler to benefits delivery of construction projects using uncertainty modelling. The paper adopts a Dempster-Shafer approach using probability theory. This is combined with Quality Function Deployment for user and design requirements capture and management. A conceptual model is suggested that forms a basis for future validation and evaluations in action research in various contexts. The Paper introduces a novel approach to uncertainty modelling in FED to support decision making. The Dempster-Shafer Bayesian based approach also contributes to new ways for capturing contextual influences to benefits realisation.

The primary goal of this paper is to present the application potential of MCDM/MCDA (multi-criteria decision-making/multi-criteria decision analysis) methods in the field of architecture and urban planning and in energy efficient construction, especially in the context of sustainable development paradigm. The first part of this paper is devoted to literature studies pertaining to multi-criteria decision-making support in the selected fields. On the basis of the delivered review, it was demonstrated that the most popular methods belonging to the MCDM/MCDA group that have been used so far for the purpose of resolving selected decision-making challenges, is the AHP (analytic hierarchy process) method with modifications, TOPSIS (technique for order of preference by similarity to ideal solution) method, as well the up-and-coming COPRAS (complex proportional assessment) method. In addition, by reviewing the literature, it was found that MCDM/MCDA methods constitute an effective support tool at the stage of evaluating and selecting project solutions, and are especially helpful in framing various social, economic, environmental criteria that are permanently linked to the rule of sustainable development. The empirical section of this paper, through a case study, presents a comparative analysis of the classical AHP method with its extension onto fuzzy sets. The case study pertained to the criteria for the location of single-family residential buildings with solar installations.
