Introduction

The continued growth of inhabitants and industrialization in developing countries necessitates more housing and offices (Ishola, Ojo & . Olaoluwa, 2015). As a result, waste generation has increased in developing countries due to a wide range of construction projects to provide additional infrastructure. Waste generation has serious negative environmental impacts, making its management necessary to have a healthy environment (Kofoworola, 2006; . Chandrakanthi, Hettiaratchi, Prado & Ruwanpura, 2002 cited in Oladiran, 2008; Kareem et al., 2014; Musa, Ashiru & Jibrin , 2015).

Environmental Waste Management Practices in Construction Projects

Waste Management Plans (WMPs): Waste Management Plans (SWMPs) are legal and mandatory requirements in some parts of Great Britain for projects valued at £300,000 and over (NetRegs, n.d.; Waste and Resource Action Program (WRAP), n.d. (Papargyropoulou et al ., 2011).In Lagos, waste, including construction waste, is dumped around street lamp posts and roadside verges (Ajayi et al., 2008).Kofoworola's (2006) reports were on landfills, while Kareem et al. 2014) were on construction sites; this indicates that fewer materials are being recovered or recycled on construction sites.

Research Method

The facility is the first of its kind in Nigeria; in the first phase, the facility will require approximately 130 trucks of waste daily to process various types of waste into raw materials for the plastic and rubber industries (“Fashola commissions N1bn recycling plant in Igando”, 2015). Governor Babatunde Fashola said the facility is a conservation strategy to tackle the threats of climate change and demonstrate the state government’s commitment to improving the environment and creating economic benefits (“Fashola commissions N1 billion recycling plant in Igando ”, 2015). Dubanowitz (2000) examined the design and operation of a 150 ton/day (876,000 t/yr) recyclable waste plant in New York; the study states that the facility would save $46 million annually in the city's waste management.

Findings and Discussion 1 Demographic information

Zero waste: respondents are aware of strategies in this category, except for the use of recyclable materials (2.91). It can be implied that government legislation has helped raise awareness of two practices in this category. Further questions revealed that most respondents are not sure about the destination of their waste.

Table 2: Awareness of Environmental Waste Management Practices

Conclusions

Air quality strategy: Construction site contractors use measures to reduce dust during construction (3.86), while the maximum emission level considered for development application is not used (2.86). Further questioning revealed that the state government regulates the use of equipment on construction sites. This result shows that the “exchange of building materials” among professionals is not trending, which supports Kofoworolo (2006) that scavengers collect items.

Recommendations

The purpose of this paper is to investigate the causes of quackery in construction accounting practices to address the threat to improved service delivery. The respondents were asked to rate the identified 34 causes of quackery in construction accounting practice on a 5-point Likert scale. The identified causes of quackery in construction accounting practices will be useful in the formulation of policy and serve as a future research agenda to eradicate the menace and achieve an improved service delivery.

An Overview of Quackery in Built Environment Professions in Nigeria

These competencies are aimed at executing projects that meet clients' value expectations (Olanrewaju and Anahve, 2015). However, quackery has caused much damage to the practice of the profession, with attendant consequences for the protection of quantity surveying services and construction project delivery in general. This paper therefore reports the results of an exploratory survey aimed at investigating the causes of quackery in the profession and factoring them into key components.

Causes of Quackery in Quantity Surveying Practice

Olanrewaju and Anifowose (2014) determined that rivalry among the professionals in the industry causes professional quackery. Ede (2011) opined that when trained professionals operate illegally (without license) within the various construction fields, quacks tend to infiltrate the profession. From the review carried out, it appears that quackery in quantity surveying practice is widespread and cannot be underestimated.

Research Method

Nnadi and Alintah-Abel (2016) added the problem of unwillingness to pay for professional services, especially among private construction clients. 2016) considered the difficulty of clients in identifying the right professionals and the opinion that the same results will be achieved when non-professionals have to carry out construction projects as instrumental to the prevalence of quackery. Dahiru, Salau and Usman (2014); and Babalola and Anifowose (2015) have also alluded to the naivety of clients, due to the restriction to advertising of professional services in accordance with the Code of Professional Conduct, as contributing to the menace of quackery. Njoroge (2013) stated that the absence of an effective regulatory framework (i.e. poor implementation of existing policies and programs or lack of harmonization and coordination) creates quackery in a profession.

Data Analysis

Jimoh (2012) also supported the fact that the role of a particular profession, if not properly appreciated by the public, can lead to quackery. There are many factors responsible for the actions that need to be critically examined to improve quantity surveying services.

Results and Discussion 1 Respondents’ information

Weaknesses in the investigative structures of the professional association and the regulatory body Lack of political will in regulating the activities of quantity surveyors. The results were subjected to further analysis to extract the eigenvalues ​​of the factors that cause quackery in the practice of quantity measurement. The activities of the professional association and regulatory bodies are very important for the growth of the profession.

Literature review 1 The POB models

The ability to manage stress related to work conditions is influenced by the cognitive and behavioral effort an individual exerts on it (Chinyio et al., 2018). The scale consists of 48 items, and this was later reduced to 5 items using factor analysis (Diener et al., 1985). Over the years, research has linked EI to positive life outcomes and improved mental and physical health (Martins et al., 2010).

Conceptual Framework/ Hypothesis Development As previously mentioned, the integration of POB

The Life Satisfaction Scale was developed by one of the world's leading SWB researchers, Professor Ed Diener, in 1985. It is important to note that the experience of stress is conditioned by an individual's perception of control over the stressor; this can determine the behavioral, physical and psychological outcomes of such an individual. Probability sampling allows for multi-source information on the entire population due to the random selection procedure (Hamed, 2016).

Data analysis/Interpretation

2 shows the final model and its correlation coefficient, and Table 5 presents the parameter estimate of the final structural equation model. The measure "I am confident that I could cope effectively with unexpected events" is used to test the effect of self-efficacy on eustress. Optimism involves the mindset of expecting good things in the future; this has a significant, negative impact on eustress.

Conclusions

Management of Theft and Vandalism at Construction Sites in the Southern Region of Malawi. The phenomenon of theft and vandalism at construction sites in Sub-Saharan Africa (SSA) has not been fully explored to warrant the implementation of evidence-based safety management practices (SMPs) to minimize losses and improve profit margins. profitability of projects. However, their effectiveness has been questioned as more incidents of theft and vandalism continue to occur in workplaces.

An overview of construction theft and vandalism The People’s Law Dictionary (1981) defines theft as

Therefore, crime prevention has become a major concern for players in the construction industry, as losses due to theft and vandalism can greatly affect the profitability of contractors. Furthermore, theft and vandalism remain insufficiently researched phenomena within the construction management discipline in Africa, specifically Sub-Saharan Africa (SSA). The next section defines the terms theft and vandalism and the types of crime incidents and criminals.

Factors contributing to theft and vandalism Understanding the factors that predominantly cause

Unfortunately, these SMPs are still neglected, as recently observed by Ablondeppey et al. 2020) and large contractors, according to Farinloye et al. 2012), continue to experience large losses due to theft and vandalism. Various causes of theft and vandalism, including the location of work sites, are discussed in section 3, while sections 4 and 5 highlight the costs of theft and vandalism and symmetrical measures for their prevention at work sites. Several thefts and vandalism incidents have occurred on work sites, with some of the SMPs, such as fencing and storage areas, properly in place (Berg and Hinze, 2005).

Cost of construction theft and vandalism

Material shortages are attributed to manufacturing and supply chain logistics challenges for import-dependent products and the inability to meet local demand from local suppliers for locally produced materials (Rahman et al., 2017). High demand for construction materials in local markets may create an appetite for theft of materials with monetary value, which according to Ablordeppey et al. 2020), can be sold to readily available buyers in the steal-to-order business. The authors suggest strengthening safety on construction sites, especially in the moments before and after a hard failure or failure.

Construction job sites security measures 1 Perimeter fencing

Unfair dismissal of employees is the cause of many cases of workplace crime (Berg and Hinze 2005; Farinloye et al., 2012). It was a highly rated safety measure for the protection of construction assets (Ablordeppey et al., 2020) and a frequently used measure in workplaces (Sharma and Bausman, 2009). Administrative processes have proven effective in mitigating crime on construction sites (Sharma and Bausman, 2009).

Research Methodology

The collected data were coded to obtain numerical values ​​and then exported to IBM Statistical Package for Social Sciences (SPSS) version 20.0. Descriptive statistical methods of mean score and standard deviation were used to determine the SMPs used by contractors on construction sites. The prevalence of SMPs in the "always used" category can be attributed to the location of construction jobs. Commonly, theft and vandalism in construction sites have been attributed to the implementation of minimally inferior measures (Sakurai et al., 2008), most of which are SMPs in the 'always used' category.
