LITERATURE REVIEW
Conceptual Framework
Construction Safety
Given the increased danger of accidents and injuries related to construction sites, construction safety is a major concern in the business. Compared to other industries, construction work is more likely to involve heavy machinery, heights, and unstable conditions, which increases the risk of workplace hazards (Hinze, 2013). In addition to worker safety, ensuring safety in construction encompasses ethical, legal, and financial concerns.
Construction hazards are broad and can vary from falls, electrocution, and being struck by things, to health concerns due to exposure to dangerous materials like asbestos (Sawacha, 1999). The management of these dangers becomes more challenging due to the dynamic and transient nature of construction sites. Construction sites, in contrast to stationary industrial settings, are dynamic environments that call for flexible and watchful safety management procedures (Lingard and Rowlinson, 2005).
Training, safety rules, and the use of protective gear are all necessary for effective safety management in the construction industry. Reducing accidents requires workers to get basic safety awareness and practice training (Goetsch, 2019). Furthermore, maintaining a safe workplace depends heavily on following safety laws and guidelines, such as those established by the US Occupational Safety and Health Administration (OSHA) (Manuele, 2013). Modern technological developments have created new avenues for enhancing building site safety. The usage of wearable technology, drones for site surveillance, and AI for risk assessment are examples of how technology can contribute to early hazard detection and prevention (Li, 2019). Along with increasing safety, these technologies help increase construction projects’ productivity and efficiency.
Even though strict safety procedures are acknowledged to provide advantages, the construction sector frequently encounters difficulties putting them into effect. According to Hughes (Ferrett 2016), these difficulties include financial limitations, opposition to change, and a lack of safety culture among employees and management. A combined effort from legislators, building companies, and labourers is needed to overcome these obstacles in the construction sector. Because construction safety is a complex problem, it necessitates a diverse strategy that includes advanced technology integration, regulatory compliance, and training. To lower the high accident rates and guarantee the well-being of construction workers, it is imperative to address the difficulties associated with putting safety measures into practice.
Safety Challenges in the Construction Industry
The construction sector is well known for being dangerous, with high accident and injury rates. Compared to workers in other industries, construction workers have a noticeably higher risk of occupational injuries, according to Hallowell and Gambatese (2009). This is explained by the special characteristics of building sites, which are frequently dynamic, and intricate, and entail a range of high-risk activities. Construction sites present a wide range of complex risks. For example, falls from a height continue to be one of the industry’s top causes of fatalities (Dong, 2012). Electrocution, being struck by things, and getting trapped in or between pieces of equipment are other frequent dangers. These dangers are made worse by the temporary character of construction sites, which have shifting settings and multiple teams working at once (Sawacha, 1999). Safety results are greatly impacted by the safety culture that exists in construction companies. According to a study by Zohar (2010), accident rates can be considerably lowered by having a strong safety culture that is defined by common safety ideals and practices. Conversely, a lack of such a culture typically leads to risky worker behaviours and practices, contributing to increased accident rates (Mohamed, 2002).
Numerous variables make effective safety management in the construction industry difficult. Budget constraints often limit the ability to spend on safety training and equipment (Loosemore, 2003). Complicating safety management efforts further is the multiplicity of subcontractors and personnel on a building site, which can result in inconsistent safety standards and communication problems (Lingard and Rowlinson, 2005).

RESEARCH METHODOLOGY
Research Design
The research design selected for this study is the survey research design. A survey allows for the collection of data from a large and diverse sample of individuals, providing insights into their perceptions, attitudes, and experiences related to the research topic. In this case, the survey focused on gathering data on assessment of green technologies in managing construction safety.
Study Area
Anambra State is a Nigerian state located in the South-eastern region of the country. The state was created on 27 August 1991, Anambra state is bounded by Delta State to the west, Imo State and Rivers State to the south, Enugu State to the east and Kogi State to the north. The state’s capital is Awka, while the state’s largest city is Onitsha which is regarded as one of the largest metropolis in Africa. Nnewi is the second largest commercial and industrial city in Anambra State and also a known automobile hub within Nigeria and Africa.
The state name was formed in 1976 from the former East Central State. The state is named after Omambala River, a river that runs through the state. Anambra is the anglicized name of the Omambala. The city of Onitsha, a historic port city from the pre-colonial era, remains an important centre of commerce within the state, while Nnewi is the second largest commercial and industrial city in the state. Nicknamed the “Light of the Nation, Anambra State is the fourteenth most populous state in the nation, although that has seriously been argued against as Onitsha, the state’s biggest and most populous urban area was discovered to be over 8.5 million in population in 2022 by Africapolis which makes Onitsha one of the largest urban areas in Nigeria by population. The area currently known as Anambra State has been the site of numerous civilizations since at least the 9th century AD, including the ancient Kingdom of Nri, whose capital was the historic town of Igbo-Ukwu within the state. Residents of Anambra State are primarily Igbo, with the Igbo language serving as a lingua franca throughout the state. Awka is the capital city of Anambra state, Nigeria. The city was declared capital August 21 1991, after the creation of Anambra and Enugu state, which moved the capital from Enugu to Awka.

SUMMARY, CONCLUSION AND RECOMMENDATIONS
Summary of Findings
The study investigated the application, benefits, challenges, and adoption levels of green technologies in construction safety within Anambra State. Through both quantitative and qualitative methods, the findings provided a comprehensive understanding of how green technologies are integrated into safety practices, their perceived effectiveness, and the barriers to their implementation.
The demographic analysis revealed that most participants were actively engaged in the construction industry in Anambra State, with a significant proportion working in major construction hubs such as Awka, Onitsha, and Nnewi. A majority of respondents had over two years of experience in managing construction safety and were involved in safety or site management roles. Additionally, a high percentage of participants had received formal training in construction safety management, reinforcing the validity and relevance of their perspectives in the context of the study.
The level of awareness and adoption of green technologies was measured using descriptive statistics and one-sample t-tests. Findings showed that awareness of green technologies was relatively high, with respondents expressing familiarity with sustainable practices such as energy-efficient buildings and renewable energy sources. However, the actual adoption of these technologies in construction safety remained limited. Many participants acknowledged the potential of green technologies to improve site safety and efficiency, but access to green technology resources and noticeable increases in adoption rates were relatively low. The mean scores across questions about access and adoption suggested that while the knowledge of green technologies existed, the practical implementation faced significant barriers.
The perceived benefits of green technologies in construction safety were strongly supported by the findings. Respondents believed that green technologies significantly improved worker safety, reduced accidents and injuries, and led to long-term cost savings. The data also suggested that implementing green technologies enhanced the overall efficiency of safety management on construction sites. Qualitative insights from interviews supported these quantitative findings, with participants sharing specific examples of projects where green technologies, such as sensor-based monitoring systems and sustainable materials, contributed to reduced risks and better safety outcomes. The overall sentiment was that green technologies had a positive impact on fostering a safety-conscious culture among workers, with some evidence of improved attitudes toward safety practices after their introduction.
Challenges to adopting green technologies were identified as significant barriers to their widespread use. Quantitative data indicated that initial costs, technical challenges, and a lack of sufficient training opportunities were among the most pressing issues. High mean scores for questions about cost and technical barriers highlighted the financial and logistical difficulties that construction professionals faced when attempting to integrate green technologies. Qualitative findings from interviews further revealed that limited support from regulatory bodies and institutional resistance compounded these challenges. Several participants pointed out that the lack of compatibility between some green technologies and local construction practices created additional difficulties, especially in projects involving traditional building materials.
Respondents also noted that while training opportunities existed, they were not sufficient to prepare professionals for the technical complexities of green technology implementation. This was particularly evident in observations from interviews, where participants described gaps in practical knowledge and hands-on experience with these technologies. Some respondents suggested that existing training programs needed to be tailored to address the specific needs of construction professionals in Anambra State.
Legal and regulatory challenges emerged as another key theme. Quantitative findings showed that participants perceived significant legal and policy-related hurdles in adopting green technologies. Interviews corroborated this, with respondents citing a lack of clear government policies and incentives to encourage the use of green technologies. Participants expressed frustration over inconsistent enforcement of safety regulations and limited government support in addressing the financial burden associated with adopting sustainable practices. This lack of regulatory clarity was seen as a major disincentive for companies that might otherwise invest in green technologies.
Despite these challenges, there was a consensus on the need for greater adoption of green technologies in construction safety. Respondents provided recommendations for improving adoption rates, including increasing government incentives, offering subsidized access to green technology resources, and enhancing training programs. Participants emphasized the importance of collaboration between industry stakeholders and policymakers to create a more conducive environment for green technology adoption.
Observational data collected from construction sites provided additional context to these findings. The presence of green technologies, such as solar panels, energy-efficient lighting, and water conservation systems, was observed on some sites, but their integration into safety measures was inconsistent. Basic safety practices, such as the use of personal protective equipment and proper scaffolding, were widely implemented, but the use of green technologies to augment these measures was less evident. Training materials on green technologies and their role in safety management were found to be insufficient, further underscoring the need for targeted educational initiatives.
The qualitative interviews offered deeper insights into the lived experiences of construction professionals and their interactions with green technologies. Participants highlighted the potential for these technologies to revolutionize construction safety practices, but they also acknowledged the systemic barriers that hindered progress. While many expressed optimism about the future of green technologies in the industry, they stressed the importance of addressing cost, training, and regulatory challenges to ensure sustainable adoption.
In summary, the findings demonstrated a clear awareness of the benefits of green technologies among construction professionals in Anambra State, coupled with an acknowledgment of the substantial barriers to their adoption. Although respondents recognized the potential of these technologies to enhance safety and efficiency, challenges related to cost, training, and regulatory support limited their practical application. The results underscored the need for concerted efforts from industry stakeholders, policymakers, and educational institutions to overcome these barriers and promote the adoption of green technologies in construction safety management.
Conclusion
The results of the one-sample t-test provided valuable insights into the awareness, adoption, perceived benefits, and challenges associated with green technologies in construction safety within Anambra State. The findings demonstrated a high level of awareness among construction professionals regarding green technologies and their potential applications in safety management. Respondents were familiar with sustainable practices and acknowledged the role of green technologies in improving safety outcomes. However, despite this awareness, the adoption of green technologies in actual construction projects remained limited.
The perceived benefits of green technologies were strongly supported by the data. Respondents believed that green technologies improved worker safety, reduced accidents and injuries, and enhanced the overall efficiency of safety management. The mean difference scores and significant t-values highlighted the consensus on these positive impacts. However, the findings also revealed that while professionals recognized the long-term cost savings associated with green technologies, the initial costs and technical complexities posed significant barriers to their implementation.
The study further identified challenges such as insufficient training opportunities, limited access to green technology resources, and regulatory hurdles as critical obstacles to adoption. Respondents emphasized that these barriers, along with the perceived lack of government and institutional support, undermined efforts to integrate green technologies into construction safety practices.
In conclusion, the findings underscored the need for strategic interventions to bridge the gap between awareness and adoption of green technologies. Addressing cost concerns, enhancing training programs, and fostering regulatory support are essential to overcoming these barriers. Promoting collaboration between stakeholders and policymakers will be critical to enabling the widespread adoption of green technologies and leveraging their full potential to improve safety outcomes in the construction industry.
Recommendations
Based on the findings, the following recommendations can be made to enhance the adoption and effective application of green technologies in construction safety:
- Government Support and Incentives: The study highlighted the lack of sufficient government support for the adoption of green technologies. It is recommended that the government implement policies and provide financial incentives or subsidies to encourage the use of green technologies in construction safety. This could include tax breaks or funding programs for construction firms that adopt eco-friendly technologies and sustainable practices. Such measures would help offset the high initial costs associated with green technology implementation, making them more accessible to construction companies.
- Training and Capacity Building: The findings revealed a significant gap in training opportunities for construction professionals regarding green technologies. It is crucial to establish comprehensive training programs that focus on the integration of green technologies into safety management practices. Workshops, seminars, and certifications should be offered regularly to educate workers, safety managers, and other stakeholders on the benefits, proper use, and maintenance of green technologies. This will not only improve safety but also increase confidence in using these technologies on construction sites.
- Increase Accessibility to Green Technologies: Limited access to green technology resources was identified as a barrier to adoption. To address this, it is recommended that efforts be made to improve the availability and affordability of eco-friendly construction materials, safety sensors, and other green technologies. Partnerships between manufacturers and construction firms could facilitate the development of locally available green products tailored to the needs of the industry. Additionally, promoting the use of sustainable materials and energy-efficient equipment could lead to cost savings in the long term, benefiting both construction companies and the environment.
- Collaboration and Knowledge Sharing: Given the positive perception of green technologies in improving construction site safety, collaboration among stakeholders is essential. Construction firms, safety consultants, regulatory bodies, and educational institutions should work together to share knowledge, best practices, and case studies related to the successful implementation of green technologies. This collaboration could include joint research initiatives and industry forums to facilitate the exchange of ideas and solutions for overcoming implementation challenges.
- Regulatory Framework and Policy Enforcement: The findings suggest that legal and regulatory challenges hinder the widespread adoption of green technologies. It is recommended that regulatory bodies revise and strengthen existing construction safety standards to incorporate green technologies as mandatory safety measures. Moreover, clear guidelines and standards for the implementation of green technologies should be established to help construction firms comply with safety requirements. Strict enforcement of these policies would ensure that green technologies are not only adopted but also effectively integrated into safety management systems across the construction industry.
