The construction of High-Rise Buildings (HRBs) first started in the 19 th century, as a sort of vertical urban sustainable development approach trying to minimize the development environmental footprint impact. Although, the debates regarding the HRBs' pros and cons, this era has witnessed a huge boost in the construction of HRB all over the world. HRBs have transformed into an ego situation where countries not only developed ones but also developing ones have been competing against each other to develop the tallest HRB. HRBs have become a branding for the economic strength and innovative development eras of countries. HBRs have been included within new cities and added to the existing urban context, without any consideration to the ability of these areas to accommodate their social, environmental, economic, and visual impacts, especially on their direst urban context. The study aims, based on several theoretical and analytical studies, to study and record in detail the various impacts of HRBs on the urban context allocating them, based on which a computerized spatial analysis model is to be composed (HRBSAModel) using geographic information systems software (GIS) and remote sensing technology. The achieved model is expected to act as a contingency tool to mitigate the negative impacts of the existing HRB on its urban context, and as a proactive tool within the city urban design process for allocating the most sustainable location for future HRBs.

Sustainable Sand Substitutes in the Construction Industry in the United States and Canada: Assessing Stakeholder Awareness

et al. 2022

View full text Add to dashboard Cite

The United Nations has declared a global sand crisis, called for reduced sand consumption, and proposed solutions to address the crisis, including adopting sustainable substitutes for sand. The construction industry is a major consumer of sand, yet a recent study found a very low level of awareness by stakeholders of the crisis. The purpose of this study is to assess the familiarity of construction industry stakeholders with 27 sand substitute materials, grouped into five components that emerged from a factor analysis. Data were collected using a survey designed by the authors. Respondents consisted of 156 construction industry professionals located in 35 US states and 7 Canadian provinces. Stakeholders were classified according to a framework considering the level of power and interest of each stakeholder in sustainable construction projects. Hypotheses of no differences in awareness for two types of stakeholder groups were generally supported. First, no differences were found for decision makers responsible for ordering sand vs. non-decision makers. Second, for professional roles, academics were more familiar with some substitutes than those in other roles. The article concludes with implications for research and practice, with recommendations on how to increase awareness of sand substitutes among stakeholders in the construction industry.

“…The world's population is growing rapidly and is estimated to increase to about 9.8 billion by 2050 (United Nations Development and Social Affairs [UNDESA], 2017). The result of population growth and rapid urbanisation contributes to the consumption of many natural resources that leads to climate change (Ayarkwa et al., 2022). The world is experiencing the effects of global warming, depletion of resources, energy scarcity and ecological toxicity, among other unfriendly challenges to the environment which is partly attributed to construction activities.…”

PurposeThe need to adopt sustainable construction (SC) practices in project activities will be appreciated when clear benefits are known to the stakeholders in Ghana. The purpose of this study was to evaluate the perceived benefits of using SC practices in building projects.Design/methodology/approachA modified Delphi method (MDM) was used to solicit the views of an expert panel on 33 benefits identified from the literature and validated by a pilot panel to ensure robustness. Statistical tools were used to analyse the data collected. The comparative analysis among the expert panel lends credence to the strong consensus reached on the 26 benefits of SC. The consensus reached by the expert panel after the three rounds were validated using the median and important scale of 70% response rate and above.FindingsThe essential benefits included the ability to enhance efficiency and improve the overall quality of life for all. Factors such as mandatory government policies and regulations are recommended as essential drivers to promote and sustain the implementation of SC in Ghana. The findings will enhance the drive for sustainability practices in construction projects in Ghana.Originality/valueThe study contributes to the body of knowledge regarding the benefits of SC from the perspective of experts in the Ghanaian construction industry. The paper would enhance stakeholders understanding the critical benefits of promoting and adopting SC practices in building projects.
