Construction sites are among the most hazardous workplaces, exposing workers to various risks such as falls from heights, electrocution, exposure to hazardous materials, equipment malfunctions, structural collapses, and site-related accidents. In Benin City, where urban development and infrastructure expansion are accelerating, construction safety has become a critical concern for stakeholders, including construction firms, workers, regulatory bodies, and policymakers. Despite existing safety regulations, the high rate of workplace accidents continues to raise concerns about the adequacy and enforcement of site safety measures. This study critically evaluates the impact of site safety measures on construction activities in Benin City, with a focus on their effectiveness in reducing accidents, improving worker well-being, enhancing productivity, and ensuring overall project efficiency. This research adopts a mixed-methods approach, integrating both qualitative and quantitative methodologies to provide a comprehensive analysis of the subject matter. Primary data is obtained through structured questionnaires and in-depth interviews conducted with key stakeholders, including construction workers, site supervisors, project managers, safety officers, and government regulatory agencies responsible for occupational health and safety (OHS) compliance. The study also incorporates secondary data from construction incident reports, safety audits, and regulatory compliance records from agencies such as the National Occupational Safety and Health Administration (NOSHA) and the Federal Ministry of Labour and Employment. Key safety measures examined in this research include the use of personal protective equipment (PPE), the implementation of hazard identification and risk mitigation strategies, the presence and effectiveness of safety training programs, the enforcement of standard operating procedures (SOPs), emergency preparedness and response plans, adherence to xi occupational health and safety (OHS) guidelines, and the overall safety culture within construction firms. Using statistical analysis, the study establishes a correlation between safety compliance and key performance indicators such as accident frequency rates, worker efficiency levels, project timelines, and financial implications of safety violations, including compensation claims, legal liabilities, and project delays. Furthermore, qualitative insights from stakeholders provide a deeper understanding of challenges affecting safety enforcement. These include inadequate funding for safety programs, lack of worker awareness and training, resistance to compliance due to cost implications, ineffective supervision, and weak government enforcement mechanisms. The study also explores the role of emerging technologies, such as wearable safety devices, automated monitoring systems, and Building Information Modeling (BIM), in enhancing safety measures and reducing risks in construction sites. Findings from this research are expected to reveal critical gaps in existing safety practices while identifying areas for improvement. The study aims to provide evidence-based recommendations for enhancing safety policies, strengthening compliance with regulatory frameworks, fostering a proactive safety culture, and integrating innovative safety technologies into construction site management. The research underscores the importance of prioritizing worker safety not only as a moral obligation but also as a strategic approach to boosting productivity, reducing project costs, and improving overall construction efficiency. Ultimately, this study contributes to the broader discourse on construction safety in Nigeria, serving as a valuable resource for construction companies, policymakers, safety practitioners, and regulatory bodies seeking to implement sustainable safety interventions. By reinforcing site safety measures, the construction industry in Benin City can achieve a xii safer, more efficient, and more productive working environment, aligning with global best practices in occupational health and safety

This study examines urban regeneration and slum upgrading in Ogida District, Benin City, with the aim of developing a sustainable framework that can guide the improvement of living conditions in the area. Ogida is one of the older residential districts in Benin City and over time has experienced significant physical deterioration, inadequate infrastructure, and growing socio- economic challenges that have contributed to its classification as a blighted inner-city neighbourhood. The study was motivated by the absence of a coordinated, community-driven regeneration strategy for the district, despite its well-documented challenges including chronic flooding linked to clay-heavy soils and blocked drainage, deteriorating housing stock, insecure land tenure, and the progressive degradation of the ancient Benin Moat, a UNESCO-listed heritage site that passes through the area. Previous urban renewal attempts in Nigeria, particularly in Lagos and Abuja, have largely relied on demolition and forced relocation, producing displacement without sustainable improvement. This study takes a different position, arguing for in-situ upgrading as the more appropriate and humane approach. A mixed-method research design was adopted. Structured questionnaires were administered to one hundred residents of Ogida District, with a 100% response rate. Direct physical observation of the study area was also carried out alongside a review of relevant documents, policies, and empirical literature. Data were analysed using descriptive statistical methods including frequency tables, percentages, and pie charts. The findings reveal that Ogida has a predominantly young, low-income population, the majority of whom rely on informal economic activities for their livelihood. Housing conditions across the district are poor, with most buildings showing visible signs of deterioration and overcrowding. Basic infrastructure is inadequate, particularly drainage systems, roads, and waste management facilities. Flooding during the rainy season was identified as one of the most serious environmental problems affecting residents. Community participation in development planning is extremely limited, with over 74% of respondents reporting that they have never been consulted about development projects in their area, even though the overwhelming majority expressed willingness to be involved. Based on these findings, the study proposes a sustainable urban regeneration framework for Ogida District built around five pillars: infrastructure and basic services improvement, community participation and indigenous governance, environmental resilience, anti- displacement and social equity safeguards, and phased implementation with community ownership. The framework is designed as a replicable model that can be adapted for similar inner-city settlements across Benin City and Edo State. The study concludes that meaningful regeneration of Ogida requires a coordinated effort involving government agencies, urban planners, traditional community leaders, and residents themselves. Without genuine community involvement and government support, physical improvements alone will not be sustainable.

Urban markets in Benin City function as vital economic spaces and cultural landmarks that reflect community identity, traditional practices and social interaction. Recent modernization efforts across Nigerian cities have focused heavily on physical redevelopment, often neglecting the cultural significance and spatial dynamics that shape these markets. This study examines the relationship between urban market revitalization and cultural sustainability in selected markets in Benin City—Oba Market, Uselu Market, Ekosodin Market, Orgie-Ode Market. Using a mixed methods approach, data were collected from 100 respondents through questionnaires, interviews, field observations and photographs. Findings indicate major infrastructural and organizational challenges, including inadequate drainage, sanitation, security and spatial planning, which affect market efficiency and user experience. Despite these issues, traders and users maintain strong cultural attachment to the markets, underscoring their historical and symbolic importance. The study concludes that revitalization strategies must integrate cultural preservation with infrastructural improvement to ensure sustainable and socially inclusive market renewal. Recommendations emphasize participatory planning, heritage-sensitive design and improved governance frameworks.

The construction industry is one of the largest consumers of natural resources and a major contributor to environmental degradation due to excessive material consumption, energy use, and waste generation. Conventional construction practices typically operate under a linear economic model, which follows the process of “take, make, use, and dispose.” This model has been widely criticized for promoting unsustainable resource use and increasing environmental pressure. In response to these challenges, the circular economy (CE) has emerged as an alternative framework that promotes sustainability through resource efficiency, waste reduction, material reuse, and lifecycle optimization in building construction and design. This research examines the circular economy as a sustainable approach to building construction and architectural design, with particular focus on its relevance and potential application within the Nigerian construction industry. The study investigates the principles of circular economy, evaluates global practices in circular construction, and assesses the level of awareness and implementation of circular economy strategies among individuals within the construction-related field.A mixed research approach was adopted, combining an extensive review of relevant literature with empirical data obtained through a structured questionnaire survey. The questionnaire was distributed through Google Forms to students, student architects, architects, engineers, and other participants familiar with construction activities, particularly within Benin City and the University of Benin community. A total of 52 valid responses were collected and analyzed using descriptive statistical methods such as frequency distribution and percentage analysis. Charts and graphical illustrations were also used to present the findings clearly. The results indicate that although awareness of circular economy concepts is gradually increasing, the actual implementation of circular construction practices within the Nigerian construction sector remains relatively low. Major challenges identified include limited awareness and technical knowledge, high cost of sustainable materials, lack of supportive policies and regulations, and resistance to change within traditional construction practices. Despite these barriers, the findings suggest that the adoption of circular economy principles has significant potential to improve sustainability in the built environment by reducing construction waste, conserving resources, and encouraging innovative design solutions. The study concludes that integrating circular economy strategies into building construction and architectural design can contribute significantly to sustainable development in Nigeria. It therefore recommends increased awareness, policy support, professional training, and the incorporation of circular economy principles into architectural education and construction practices

The rising demand for sustainable and affordable housing in Nigeria has drawn attention to the use of environmentally friendly and cost-effective building materials. This study explores the potential of timber as a construction material for sustainable and affordable housing and building development in Benin City, Edo State. Timber, being a renewable and locally available resource, offers significant advantages in terms of energy efficiency, reduced environmental impact, and economic viability. The research assesses the level of timber adoption in the local construction industry, evaluates its suitability in terms of structural performance, cost, and sustainability, and examines the challenges hindering its widespread use. Findings indicate that while timber is perceived positively for its aesthetic and thermal qualities, concerns regarding durability, fire resistance, and regulatory gaps remain key obstacles. The study concludes that with proper treatment, policy support, and awareness campaigns, timber can play a critical role in addressing Nigeria's housing deficit sustainably and affordably. Recommendations are made for policymakers, architects, and developers on strategies to promote timber adoption in future building projects.

This study examines the economic potential of household organic waste management and its architectural implications for sustainable environmental design in Ekosodin Community, Benin City. Household organic waste, including food leftovers, vegetable and fruit peels, and garden waste, constitutes a significant portion of municipal solid waste, yet its economic and environmental value remains largely untapped. The research adopted a mixed-method approach, employing structured questionnaires administered to 100 households, key informant interviews with architects and waste management officials, and field observations. Data were analyzed using descriptive statistics, including frequency distributions and percentages, and interpreted in relation to sustainable design principles. Findings reveal that open dumping and burning are the predominant disposal methods, while composting and waste segregation are minimally practiced. Most households lack designated spaces for organic waste storage and management, indicating a critical gap in residential architectural design that could facilitate sustainable waste handling. Awareness of the economic potential of organic waste was generally low, limiting participation in composting, urban agriculture, and biogas production initiatives. The study concludes that integrating waste-responsive design features into residential architecture, coupled with public awareness campaigns, infrastructural support, and policy enforcement, can transform household organic waste into valuable resources while promoting environmental sustainability. Recommendations include incorporating designated waste management spaces in building designs, establishing community composting centers, and implementing economic incentives for organic waste valorization. This research contributes to the understanding of the intersection between household waste management, architecture, and sustainable environmental design in Nigerian urban.

Architectural facades play a vital role in shaping the identity, functionality, and aesthetic appeal of buildings, particularly in urban environments. This research investigates the incorporation of architectural facades in buildings within Benin City, Edo State, focusing on their social, cultural, and environmental impacts. The study explores how façade design contributes to the character of the built environment, enhances user experience, promotes climate responsiveness, and reflects local identity. Despite their significance, many buildings in Benin City lack thoughtful façade integration due to limited awareness, economic constraints, and insufficient design regulation. Through field observations, case studies, and stakeholder interviews, this research examines existing façade applications and identifies best practices for context-appropriate designs. The findings reveal that well-designed facades improve urban aesthetics, increase building efficiency, and foster a stronger sense of place. The study concludes that a deliberate approach to façade integration considering climate, culture, and functionality are essential for sustainable urban development. Key recommendations include promoting design education, enforcing architectural standards, and encouraging innovation to support meaningful façade design in Benin City. This research offers practical insights for architects, developers, and policymakers committed to enhancing the urban fabric through facade-conscious architecture.

The construction industry in Nigeria faces significant challenges in balancing economic growth with environmental sustainability. This study compares traditional and modern building materials in Nigeria, focusing on their sustainability and environmental impact. Traditional material (mud, thatch, bamboo). Are evaluated alongside modern materials (e.g., concrete, steel, glass) using Life cycle Assessment (LCA) and case studies. The research investigates the environmental implication of material extraction, processing, construction, and disposal. Factors such as energy consumption, greenhouse gas emission, and indoor air quality are assessed. The study reveal that traditional materials exhibits superior sustainability characteristics, including lower carbon footprints, reduced waste generation, and enhanced thermal performance. However modern materials offer improved durability and structural integrity. Policy and regulatory frameworks analyzed to identify barriers to sustainable building practices.

This study investigated the behavioural and psychological effects of hostel accommodation on students of the University of Benin (UNIBEN). The study adopted a descriptive survey research design to examine how hostel living conditions influence students’ behaviour, mental well-being, and academic experiences. Data were collected from 101 hostel residents through a structured questionnaire administered electronically, consisting of both quantitative and qualitative items. Quantitative data were analyzed using descriptive statistics such as frequencies and percentages, while qualitative responses were analyzed through content analysis. The findings revealed that hostel accommodation contributes to positive behavioural outcomes such as increased independence, social interaction, and adaptability among students. However, challenges including noise, peer pressure, overcrowding, and poor facilities were found to negatively affect concentration and behaviour. Psychologically, many students reported experiencing stress, anxiety, and homesickness, largely due to inadequate maintenance, inconsistent water and electricity supply, limited privacy, and overcrowding. The study also found that improved facilities, regular maintenance, counselling services, and recreational spaces were widely perceived as effective strategies for enhancing students’ well- being and academic performance. The study concludes that hostel accommodation has a significant influence on both the behavioural and psychological well-being of UNIBEN students. It recommends improved hostel management, reduced overcrowding, enhanced facility maintenance, and the provision of student support services to create a more conducive and supportive living environment.
