“…Considerable information and knowledge sharing will be expected to occur in such circumstances but is often found lacking (Salas et al, 2017 ). Ekström et al, ( 2019 ) have advocated for a change in construction project culture to embrace more collaboration and social interactions amongst project delivery teams, so that they are able to solve mutual issues.…”

The land development process in New Zealand is criticised for causing delays in the delivery of adequate housing. These delays upset the demand and supply equilibrium, leading to housing shortages, expensive builds and rentals. This study investigates the challenges in land development, to ascertain the factors that are limiting its efficiency as a major catalyst to housing provision. An understanding of the complexities of the development process could enable the suggestion of feasible solutions for achieving housing goals. A two-stage process was adopted to achieve this study objective. In stage one, a critical review of relevant literature helped to identify 48 measurement items. Those items were included in a questionnaire survey in the second stage, to gather data from stakeholders involved in land development process in New Zealand. Using relative importance index (RII) method, nine significant challenges were identified, which were then categorised and discussed in accordance with the construction stakeholder groups that are responsible for creating those challenges. The nine major challenges are: delay in reviews and approval of documents; scope change; lengthy consent application processes; late response to queries by regulatory authorities; poor interaction between regulatory authorities; poor coordination within regulatory authorities; poor planning and scheduling; design errors and slow progress during design development. Findings of this study highlight the need for the development of proper workplan for consent processing, reasonable factoring of the risks associated with scope changes in the land development process, and the enhancement of project management skills of land development contractors.

“…To implement sustainable development fully in an organization or project group, it is highly important that both the decision making and content of structural performance, economy and environment are broken down to different levels. Such levels can be at organization, project or individual level [11,14]. Also, a fourth level can be added representing technology development, such as a seamless information flow and design methodologies that investigate thousands of design alternatives.…”

Estimates indicate that the total climate impact, from a lifecycle perspective, generated by Swedish construction processes reaches the same magnitude as emissions from all passenger cars in Sweden. A large part of the emissions from construction of roads and railways arise from production of steel and concrete used in bridges and other infrastructure structures. In this research, several cases of existing concrete bridges have been investigated. The case studies are in a very firm way analyzed, and then opportunities for reducing climate gas emissions are described and elaborated upon. Accordingly, design and dimensioning through the use of today's technology and material selection are discussed. Without developing new ways to construct bridges, or comparing concrete with other materials, a useful guide on how to use technology and opportunities that are available for constructing climate smarter versions of standard bridges today is developed and described.

“…It is a common approach to employ a quantitative approach in previous studies related to Importance-Performance Analysis. One of most common approaches is to employ a five-point Likert scale to measure importance and performance [25][26][27]. Therefore, a five-point Likert scale was employed in this study to measure the importance and performance levels of the management of each individual risk perceived by industry practitioners.…”

Risks in Prefabricated Buildings in China: Importance-Performance Analysis Approach

2019

View full text Add to dashboard Cite

Prefabrication has drawn wide attention in China during the last decade. However, the market share of prefabricated buildings in China remains comparatively low. The Importance-Performance Analysis approach is employed in this study to investigate the crucial risk factors associated with prefabricated buildings in China. A preliminary list of risks associated with prefabricated buildings in China was developed based on a critical literature review, which was consequently refined by the interview with related experts. A questionnaire survey was then conducted with selected industry professionals to solicit their expert opinions of critical risks associated with prefabricated buildings in China. Findings show that attention should be paid to the following risks: improper decomposition system, low level of factory management, incompetent quality assurance system, deviation in specification of prefabricated components, defects of component system, missing catalogue of building parts and components, poor adaptability of prefabricated building during the operational stage, and lack of actual cases to prove the environmental benefits of prefabricated buildings. This study also revealed the discrepancy between perceived critical risks and those risks with comparatively lower management performance. These findings offer useful inputs for the future development of prefabricated buildings in China and beyond.
