“…Moreover, the CoQ aligns areas requiring further improvement and justifies quality strategies financially. Several studies have used the CoQ to evaluate construction projects with the Prevention-Appraisal-Failure (PAF) model [23][24][25]. The PAF model operates on the premise that investments in prevention and appraisal activities have a cascading effect on the failure costs.…”

The quality performance of a green building will have an overarching effect on its objectives because of the high compliance needed to achieve superior performance expectations. Achieving sustainability objectives is challenging and requires the collaboration of diverse professionals that resume unique responsibilities. In this study, the different managerial practitioners involved in green-building projects were investigated in terms of their awareness levels regarding the quality performance measures, their perceived abilities to influence quality failure consequences, the degree to which the cost-of-quality (CoQ) of components can be evaluated, and the effect the sustainability traits have on the quality performance. Accordingly, a survey approach was adopted, and the results were analyzed using Pearson’s chi-squared (χ2) test, the relative importance index (RII), Mann–Whitney U-Test, and Student’s T-test. According to the results, the priorities of the different managerial types and their overall impressions of cost computability were different, which needs to be considered when CoQ evaluations are done based on practitioners’ views. In addition, the sustainability traits of green buildings impact achieving quality metrics with the consequences of design rework occurring in the construction stage may lead to denouncing sustainability traits. The results of this research study reveal the need to consider the differences between managerial types when evaluating CoQ for projects and the increased sensitivity for such evaluation in a green building context. The paper contributes to underscoring the important connection between quality performance and sustainability traits of a green building project and calls for researchers to formulate methods with more rigor to reach a set structure for quality cost accounting as an industry standard. Intricate evaluation methods will enable strategic decision making on quality performance budgets to be more substantiated.

Construction companies execute many projects simultaneously. In such situations, the performance of one project may influence the others positively or negatively. Construction professionals face difficulties in managing multiple projects in limited resource situations. e purpose of this study is to identify the problems in multiproject scheduling from the practitioner's perspective and to discover current practices under resource unconstrained and constrained settings. e specific objectives are (1) determining the most challenging issues being faced in handling multiproject environment, (2) enumerating the practices adopted in the industry, and finally (3) identifying the practitioners' perceptions on the multiproject scheduling aspects such as network modeling approaches; activity execution modes; concept of sharing, dedicating, and substituting resources; centralized and decentralized decision-making models; solution approaches; and tools and techniques. An online questionnaire survey was conducted to address the objectives above. e top challenging issues in managing multiproject environment are identified. Factor analysis identified the factors by grouping the variables (a) decision-related, (b) project environment-related, (c) project management-related, and (d) organization-related factors. Resource-unconstrained situation mainly faces the issue of underutilization and wastage of resources leading to lower profit realization. e following findings were identified to overcome the unconstrained resource situation such as identifying the work front, adopting pull planning approach, creating a common resource pool, and allotting it on a rental basis. On the contrary, resource-constrained situation faces the issues of prioritization of resources, coordination, communication, collaboration, quality issues, and rework. e findings suggest the strategies such as topup via subcontracting, proactive pull planning, introducing buffers, training the culture of the organization towards better communication, coordination, and collaboration, to improve the reliability of achieving baseline project performances. Various multiproject aspects suggested for effective management. e identified problems, practices, and various multiproject aspects are expected to contribute better management of multiproject resource unconstrained and constrained project scheduling.

For construction companies and other stakeholders, quality failures cause rework, repair, and other losses, and even impact on poor construction performance and energy-saving inefficiency [12,31]. At the project level, time, money, and other resources are wasted because of reworks and poor construction performance caused by quality failures [31][32][33].…”

At the project level, time, money, and other resources are wasted because of reworks and poor construction performance caused by quality failures [31][32][33]. The quality of both energy performance and the cost optimality is necessary to promote and analyze in construction projects, as stated in several [34][35][36][37].…”

Building energy renovations contribute significantly to energy sustainability and environmental protection. These advantages have increased the importance of renovating existing residential buildings in many countries. In China, the government has supported the energy-saving renovation of existing urban residential buildings since 2007. However, quality failures, which do not meet the technical requirements, occur during construction processes in building energy renovation projects. Although quality failures are regarded as a crucial problem in building energy renovation projects, the identification of quality failures and their sources, likelihood, impacts, and causes remain mostly unknown. This paper investigates the nature of quality failures in building energy renovation projects. A total of 25 quality failures were first identified through five cases, and interviews with six experienced construction professionals in China. A questionnaire survey was further conducted to evaluate the frequency of quality failures. The results show the nature of quality failures that arise during construction and their sources, occurrence frequency, causes, and impacts. The research reveals that quality failures are caused by defaults by workers; inadequate checking procedures; incomplete construction site surveys; inaccurate design work; fraud of construction companies; and inefficient cooperation between different departments. Above all, the behaviors of the main actors are responsible for poor construction quality. Additionally, emphasis on quality control during the renovation preparation stage is critical to ensure that quality failures are reduced in numbers and severity.
