Strategies to Reduce the Impact of Resource Consumption in the Ghanaian Construction Industry

Abstract

With a growing priority on resolving environmental issues and managing resources more effectively in line with Sustainable Development Goal 12, this research aims to assess solutions to minimize resource consumption in the Ghanaian construction sector. In the Ghanaian cities of Accra and Kumasi, questionnaires were utilized to solicit responses from construction stakeholders. Mean score ranking was used to rank these techniques. A reliability analysis using Cronbach's alpha coefficient found a high level of internal consistency. A high level of agreement was found after testing using Kendall's concordance. A one-sample t-test was also employed to examine the relative importance of the variables. Properties should be built to be disassembled; sections of existing building structures should be reused; prefabricated components should be utilized for on-site assembly; demolition components should be re-used or recycled, and existing buildings should be renovated to prevent destruction. This research is valuable because it adds to a checklist of measures for minimizing the effect of resource consumption in the Ghanaian construction sector, as well as to the achievement of the SDG goal. Project managers, architects, engineers, subcontractors, and other key stakeholders are encouraged to use innovative approaches to decrease resource consumption.

Fuzzy quantitative risk allocation model (FQRAM) to guide decision-making on risk allocation in Ghanaian public-private partnership (PPP) power projects

“…Land for siting power plants can either be public land or private land. For power plants that are large, there is the need to invest in structures that support generation loads (Kukah et al , 2022c). This can be done by having sites with grid connecting points having appropriate load bearing capacity.…”

“…To begin with, electricity makes use of high technological components that are custom-built (Kemausuor and Ackom, 2017). Once deployed in a remote location, there are specific connectivity and logistical difficulties encountered (Kukah et al , 2022c; Kukah et al , 2022d). The power sector includes technically demanding projects that typically include many subprojects and necessitate the incorporation of many technical fields (Carbonara and Pellegrino, 2018).…”

“…On the other hand, constructing and maintaining roads, railways and highways are the responsibility of the Ministry of Roads and Highways (Agyekum et al , 2022b; Blay Jnr et al , 2022). Contractors in the housing subsector are grouped into four classifications, 1 to 4, depending on the value of the project to be implemented (Kukah et al , 2022c). Class 1 contractors (D1K1) are contractors with the capacity to execute projects that are above US$500,000 in value, class 2 contractors (D2K2) have the capacity to execute projects that are up to a value of $500,000, class 3 (D3K3) contractors have the resources to implement projects with a maximum value of $200,000, while class 4 (D4K4) contractors have the means to carry out projects with a maximum value of $75,000 (Kukah et al , 2022c).…”

“…Program (BBB). It is globally known that the construction industry regularly consumes more raw materials, resulting in scarcity with our natural resources and produced environmental implications (Kukah et al, 2022). About 40% of the total materials reserve is intended for construction industry resource usage (Kulatunga et al, 2006).…”
