“…Past research has identified difficulties in applying tools associated with first-generation design methods, i.e., tools that aim to make all requirements explicit upfront (Sahadevan & Varghese, 2018) or to decompose problems into well-defined pieces (Lima et al, 2008). However, their theoretical underpinnings are rarely discussed.…”

Responsible for delivering major healthcare projects, the University of California in San Francisco (UCSF) has devised creative ways of reducing waste and increasing value through project delivery. In a previous paper, we described UCSF Health's journey to rethink project delivery practices. The adoption of Target Value Delivery (TVD) is a core enabler of their success. The University has consistently adopted TVD to deliver complex healthcare projects within or below their allowable costs. Previous papers have provided evidence and insights into why and how such success has been achieved. However, the focus so far has been on collaboration and cost management. This paper describes the strategies utilized to focus on and manage value generation. The term human-centered innovation was chosen to emphasize stakeholder engagement and empathy building as input to idea generation. This approach shaped how TVD is implemented in these case studies. Its analysis provided insights into complementary design and decision-making strategies traditionally used in TVD. In particular, the design strategies observed in this research expand the documentation of TVD best practices to include not only solution development strategies but also participatory and empathic ways of understanding, framing, and reframing design problems.

“…The use of CBA to address construction management problems has gained attention within the community studying and applying Lean Construction practices, including decision-making in the design phase [27,28], project team selection [29], public procurement process [30], analysis of protection devices in bridges [31], and contractor selection [32]. The literature reviewed on CBA builds on previous work to gather and organize data about a problem, which are then used to select the alternative with the best overall advantages during the CBA process.…”

CBA-Based Evaluation Method of the Impact of Defects in Residential Buildings: Assessing Risks towards Making Sustainable Decisions on Continuous Improvement Activities

et al. 2021

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.

“…The application of MCDM necessitates a systematic identification of criteria for decision making. The set of design values from a previous study on university campus design (Sahadevan and Varghese 2018) were used as criteria for applying the two techniques. The criteria of constructability and schedule were not considered in this study as the influence of these criteria on the classroom layout decision was assumed to be insignificant.…”

“…Therefore, the study of the effectiveness of the application of the two MCDM techniques for evaluating spatial design needs further exploration. A study on stakeholder values in the design of university campus buildings (Sahadevan and Varghese 2018), led to a framework for evaluating design alternatives. The framework proposes the use of MCDM technique by using stakeholder values as criteria for design decision making.…”

Arriving at a consensus in design decisions is challenging owing to the presence of diverse and multidisciplinary stakeholders with multiple design objectives. The literature on AEC design decision making have reported Analytic Hierarchy Process and Choosing by Advantages as two commonly used multi-criteria decision-making techniques for evaluation of design alternatives. However, the existing literature has mainly focused on choosing between material or technology and the comparison of the two techniques to assess the suitability for their application to non-spatial aspects of AEC design problem. The current work seeks to investigate the suitability of CBA and AHP to a layout design problem. A decision-making exercise involving a hypothetical case of evaluation of three classroom layouts was conducted. A set of criteria for design evaluation which was derived based on a previous study on stakeholder design values was used in the exercise. Conclusions were drawn based on the operationalization of the two techniques rather than a direct comparison of the results obtained from the two techniques. The findings from the study indicate that CBA aids in defining a robust set of design criteria, sub-criteria and attributes and facilitates a collaborative decision-making process. On the other hand, AHP provides a structured approach for eliciting individual participant judgments. The benefits and limitations with respect to the operationalization of the two techniques are discussed in detail.
