Item Reflections on the Impact of Urban Sprawl on the Architecture of the City: Lessons from Benin City, Nigeria(Forum Geografi, 2023) Odeyale, T. O.This paper focuses on Benin City, Nigeria, as a case study to explore urban sprawl and its associated problems resulting from unplanned and uncontrolled spatial expansion. Informal settlements house approximately 45% of Nigeria's urban population, leading to land and environmental challenges. The study aims to investigate how sustainable development goals can be realized through efficient, sustainable planning and urban design concepts, focusing on managing urban sprawl in the city. The methodology comprises a literature review, a field investigation of unplanned or squatter settlements in a selected part of Benin City through the administration of 201 questionnaires, and an analysis of its developments and physical transformations. Understanding the issues of urban sprawl arising from the rapid spatial expansion of Benin City is crucial for achieving a well-organized, planned, orderly, and sustainable environment. This paper provides valuable insights and information to facilitate effective urban planning in the study area. Additionally, it offers guidance to practitioners and developers on adopting sustainability measures in their projects. The findings of this study contribute to expanding the knowledge horizon and serve as a reference for further research on spatial expansion and the incidence of sprawl in urban centers throughout Nigeria.Item Urban decay and traffic load on highway in Nigeria: a study of Ibadan-Oyo road(Springer, 2023) Oladejo, O. J.; Odeyale, T. O.; Ogunleye, O. J.This study investigates traffic load as a cause of urban decay and failure on a highway in Nigeria, using Ibadan-Oyo road as a case study. This study identifies road failure as a major city nightmare that affects the well-being of urban dwellers in the study area. The Ibadan-Oyo road is a segment of the major road intersection that connects the southern part of Nigeria with the north. The methodology for this study involves a well-structured questionnaire administered to road users to elicit primary data on the factors and effects of urban decay due to traffic load. A total of 100 Questionnaires were randomly distributed among the road users (vehicular and pedestrians) of the Ibadan-Oyo road. In all, 92 questionnaires were returned. These were analyzed using the Relative Importance Index (R.I.I) and basic statistical tools, to better understand the trend of responses. The results from the study show the factors that enable traffic load and failure include the road as a major route to various parts of the country, not obeying driving laws, poor driving habits, and poor/absence of road pavements. The stress of heavy vehicles on the Ibadan-Oyo road also proves to be a major factor which leads to incessant failure of the road, even after maintenance or reconstruction has been carried out. The failure of this urban infrastructure and the poor road networks leads to many accidents, acute vehicular fuel consumption, waste of time, breakdown of vehicles and road rage. To drastically reduce the impact of infrastructural decay and failure on highways, this study suggests the following: construction of separate routes for trucks and other heavy vehicles, provision of various parks along travel routes for heavy vehicles, and use of a weighing bridge to regulate the range of axle load, replacement of flexible paving with a more rigid design for increased strength and road life span, proper rehabilitation and reconstruction of the failed segment, provision of an alternate railway system to convey heavy goods and also reduce the stress on road transport, in-depth training of vehicle drivers and traffic personnel and lastly, enlargement of the road width.Item Effect of Air Pollution from Pedestrian Traffic in an Open Market: A Case Study of Bodija Market, Nigeria(International Information and Engineering Technology Association (IIETA), 2020-11) Oladejo, O. J.; Odeyale, T. O.; Adiamo, B. R.Market air quality is very important to the economic lives of the people which is rarely researched, however, market activities particularly pedestrian traffic releases particulates which is detrimental to the health of the users and stakeholders. Thermo scientific MIE pDR1500 particulate was used to monitor the quality of air within the market for eight (8) weeks, air pollutant of concern is PM2.5. Ten (10) sample points were located in the market which covers ten (10) sample points for pedestrian traffic to represent the entire market environment spectrum. The analysis of PM2.5 measured daily during dry and wet season shows a clear seasonal variation of this particular pollutant as elevated concentration was measured during the dry season than the wet season. The assessment of PM2.5 concentration shows exceedances of the standards stated by WHO and NAAQS during the dry season which ranges from 47.9 μg/m3 - 231.88 μg/m3 in the morning and 65.17 μg/m3 - 1806.33 μg/m3 in the afternoon. From the findings, pedestrian traffic contributes immensely to air pollution in an open market, with this elevated concentration, prolonged exposure is highly detrimental to health. This study creates awareness to the pedestrians in an open market about air pollution and informs policy changes.Item Actor-network, conflict and the commodification of planning: Role of traditional food markets in shaping the built environment(ELSEVIER, 2020) Odeyale, T. O.This paper examines the processes of transformation of the architecture and spatial character of a Nigerian city, in (he planning and delivery of a sustainable built environment. It examines the intei dependency ot relationship between the traditional market space and the city which is constantly being challenged, adapted and simultaneously undermined by the city’s rapid growth and modernisation. Therefore, the meanings attached to the market and its built environment has not only changed on several levels front tire symbolic, sacred, religious use to commercial and mundane one but also has taken on new spatial forms in sustaining the life of the city due to the activities of tire various actors which is predicated on their worldview. Tire paper provides a detailed examination of the geographical location of the old mar ket built environment, in r elation to the expansion of the city over tittte. It traces historical changes hr the surrounding urban scape of the market, in particular, the location of developments, marry originating front tire colonial period, and their httpact on tire life of tire marker over time. It relates, how these historical relationships are registered both topographically and spatially providing supporting visual material such as maps and developmental plans. This paper fur ther expatiates on the understanding of negotiation and conflict that ensued during the inter action within the material environment of the city through the pr ism of the role of actors (government officials, users, planners, politicians) involved with the built marketplace in the snrdy area. Analyses provided through interpretive anthropology which is synchronic in nature (focus at events in a slice of rime) and those provided by Actor Network Theory (ANT) that is diachronic (focus on dynamic events through tune), i.e. anthropology focuses more ort the “static" past whereas ANT focuses on the activities of the actants in “dynamic" or "real-time". The paper concludes that theoretical and cultural interpretation impacts the physical mar ketplace, its form, character, and spatiality; this must itself be understood as an agent or actant in the struggle, in as much as it both enables and constrains human activities.Item Design toolkits for campus open spaces from post-occupancy evaluations of federal universities in South-west Nigeria(Emerald Publishing Limited, 2018) Adedeji, J. A.; Fadamiro, J. A.; Odeyale, T. O.Purpose - Participatory design strategy through post-occupancy evaluation of built assets is a feedback mechanism into the design process. This paper draws upon a wider empirical study that aims at evaluating the University Campus Open Spaces (UCOS) of six federal universities in South-west Nigeria. The purpose of this paper is to generate evidence-based design toolkits for UCOS towards spanning of disconnects between designers and users thereby revisiting and revitalizing their design criteria. Design/methodology/approach - A sample (n = 3,016) of users was drawn in a cross-sectional survey through stratified random method. The research instrument was a structured questionnaire in multiple choice and Likert-type scales. The data obtained were subjected to statistical techniques. Findings - Results show that males use the UCOS for active and passive recreation than females. The UCOS are male dominated because the females have higher concerns for lack of safety and inclement weather. Both genders have equal preference for sitting. “Group academic” activities are at peak in the “afternoon”, while “being alone” takes place in the “evening” and “personal academic” in the “morning”. Safety is primary to zoological and botanical gardens. Social interaction spaces enhance successful recreation parks. Coherence and legibility are the highest cognitive satisfaction factors for pedestrian sidewalks. Practical im plications - The research generated design requirements for UCOS, and it is important for informing better design solutions in the future. Originality/value - The results are synthesized into three-in-two new frameworks to guide future design actions for innovative strategies between design and use/operational phasesItem Evidence-Based Design of University Zoological Gardens: A Perception Study in South-west Nigeria(2018) Adedeji, J. A.; Fadamiro, J. A.; Odeyale, T. O.Evidence-based design (EBD) has become an acceptable paradigm in environmentbehaviour endeavours in recent years with documented benefits especially in healthcare facilities. However, little is known of its application to University Campus Open Spaces (UCOS) like University Zoological Gardens (UZGs) which accounts for the repetition of design mistakes. This study aims to assess the UZGs as a major component of UCOS in South-west Nigeria with a view to formulating EBD frameworks. It adopts a comparative post-occupancy evaluation (POE) approach through a Stratified Random Sampling protocol of users (n=3,016) of the gardens in Federal Universities in South-west Nigeria. Results of the quantitative data analyses suggest that while walk-ability is a primary satisfaction factor among thirty design considerations in the formulated model, legibility is the most primary cognitive factor for designing perceptible high quality UZGs. The study argues in favour of the developed framework as design tool-kit and recommends its application as a feedback input into the design process of UZGsItem Exploring New Directions for the Transformation of the Built Environment in Nigeria: The Role of Building Information Modeling(IISTE, 2016) Odeyale, T. O.; Olalekan, K.; Fagbemi, K.; Abraham, S.Building Information Modelling (BIM) offers an alternative and better method of handling information for integrated project delivery approach to that of the traditional fragmented method of collaboration in the built environment. This paper is aimed at assessing the awareness and the prospects of adopting BIM in the professional Architectural practices in Nigeria using Akure as a case study. The rate of urbanisation and transformation of the built environment in the face of globalisation, calls for a new direction in the processing and handling of building information. This is particularly necessary as the current business model is inadequate for maximum productivity. The field investigation focused on determining the current business model of selected Architectural practice as well as assessing their awareness of Building Information Modelling and whether or not professionals are going to adopt it soon. The findings showed that the method of collaboration among professionals remain fragmented, the use of 3D software and even BIM software is limited to just 3D visualization and plan details. The study revealed that despite a good number of respondents already conscious of the benefit of using a BIM tool; their overall approach to project delivery remains fragmented. Awareness of the concept of BIM was a little above average among respondents but BIM implementation in professional practice is very low. It was discovered that challenges faced by respondents in the adoption of BIM is predicated on the attitudinal disposition of other professionals with whom they work and exchange building information with. These professionals do not work with BIM and coupled with inadequate knowledge of staff in the adoption of BIM workflow. The paper concluded that Building Information Modelling (BIM) has greater advantage than the existing traditional practice involving 2D drafting. BIM also has the inherent ability to foster integrated project delivery by creating a common platform for all professionals to work simultaneously on a project thereby minimising costly design and construction errorsItem Threat to sustainable environments: reappraisal of cases and causes of building failures in nigeria(Cambridge Publications and Research International, 2015) Olalekan, K.; Odeyale, T. O.; Fagbemi, K.It is a common sight recently in the developing countries especially in Nigeria to find buildings collapsing in cities and towns. Such buildings cut across several use and function (private, corporate, religious and public), exposing innocent lives to harm and unwarranted death. This paper considers the various reasons, causes and factors at the root of this menace affecting building and sustainable environment. Some of the causes were traced back to the planning and conceptual design stages before the actual construction of the building takes place. The paper argues that the problem of building collapse and disaster is not due to lack of knowledge of its causes but in ensuring that such probable factors were programmed not to happen. This with involve putting in place, appropriate precautions from the design stage to ensure the durability, sustainability and functionality of the building through careful construction process and good maintenance.Item Social and cultural construction of healthy city in subsaharan africa: a case study of urban conflicts and modernisation agenda in ondo state, Nigeria(Cambridge Publications and Research International, 2015) Odeyale, T. O; Olalekan, K.This paper examines the processes of transformation of the architecture and spatial character of a Nigerian city, in the achievement of a healthy and sustainable built environment. Objectives: It investigates the conflicts, tensions and negotiations that take place between those city dwellers embedded in the context of traditions and those pursuing a modernization agenda at a time when new infrastructures (hospitals, food markets and Automobile Markets) are being introduced in Akure. The study demonstrates that in order to understand how the built marketplace is made, unmade and reassembled, it is necessary to know how the worldviews of market users, sellers and policymakers are both culturally and socially constructed. Method Used: Interpretive anthropology and Actor Network Theory are used to explore the unwritten ritual practices, persistent traditional values, conflicts and socio-cultural transformations that underlie the physical built environment in which the health and social facilities are located. Findings: The research shows that the character of the built environment and social infrastructures within the city is not simply an outcome of national decision making, but is driven by the cultural preferences and diverging social interests of ‘actants ’ as they negotiate the process of change between tradition and modernity and make choices.Item Millennium development goals: impact of sustainability discourses, conflict and inter-governmental actions on the built environment(Cambridge Research and Publications International, 2015) Odeyale, T. O; Olalekan, K.As part of the Millennium Cities initiative, organized by Earth Institute of Columbia University USA, Akure, Nigeria was selected as one of the cities in Sub-Saharan Africa to be assisted in achieving the millennium development goals (MDGs). Other cities selected in Sub-Saharan Africa include Kisumu. (Kenya); Blantvre. (Malawi); Kumasi, (Ghana); Bamako. (Mali); Sezou, (Mali); Kaduna, (Nigeria) and Mekelle. (Ethiopia). It is necessary to point out that this initiative focuses more on inter-governmental actions than tackling the source of the developmental problem of the cities involved in the initiative. Using a mixed methodological approach, which included participant observation and structured interviews by means of convenience and snowball sampling methods administered in the study area. According to the aim of the project it is to promote investment from overseas (capitalist) companies, create employment and help in the domestic affairs of the cities involved. This paper examine the impact of the MDGs on the built environment and critique these ‘lofty ideas' which has failed to address the local, regional and cultural specificity of the location; and which has not been productive in Sub-Saharan Africa. The paper concludes that the desire for an integrated city cannot be
