The well-being of any nation is based on its readily available and functional infrastructure. The abandonment of urban infrastructure does become a threat and causes an environmental nuisance, slowing down development. The study assesses the impact of abandoned urban infrastructure on the environmental development of Ogun State. It examines the effects of abandonment on the environment and identifies the various causes and types of abandoned urban infrastructure in the state. Questionnaires and interviews were used to gather data from estate surveyors, valuers, and end users of urban infrastructure. The data was analyzed using a descriptive analysis and the Relative Importance Index (RII). The effects of abandoned urban infrastructure on environmental development were determined to be environmental degradation, a decrease in business activities, and an increase in health issues. The study recommends that infrastructural projects should be done in bits to avoid abandonment, ongoing construction should always be kept clean to avoid negatives uses, good health care and environmental cleaning up should be done for the people, and the use of turnkey projects as well as the globally established PPP model of infrastructure delivery.

The study examined the community-based approach to finance basic public infrastructures in residential neighborhoods. The primary objectives of the study were to determine the condition of public infrastructures, the level of community engagement, the modalities of financing and the prominent influencing factors. The study adopted convenience sampling and questionnaire survey techniques. A total of 120 questionnaires were administered to residents of selected high-income communities (HICs) and low/medium-income communities (L/MICs), out of which 48 (80%) and 52 (86.67%) were retrieved, respectively, and analyzed. The study deployed descriptive statistics of mean and standard deviation models and mean weighted score to analyze the data. The study found that the residents were satisfied with the security of the neighborhoods but deplored the state of the public potable water infrastructure in both communities. However, the residents in the HICs enjoy a better condition of road infrastructure compared with L/MICs. The residents in both communities indicated a high level of involvement in the financing of public infrastructures, with major engagement in security and waste disposal/management infrastructures. However, the HICs engaged more in road grading/maintenance, while the provision of community potable water was given as a priority by the L/MICs. The major mode of financing basic communal infrastructures is through membership levy/contribution, and prominent influencing factors are cooperation among members, fundraising and income status. Therefore, while private-sector support funds, such as from the CDAs, help in cushioning the effects of basic infrastructure decay, governments at all levels should provide an enabling environment that will motivate mutual communal relationships through integrated infrastructure policies.

The development of facility management (FM) in Nigeria is relatively new and limited in scope although it has been introduced for more than four decades. This study attempts to assess the operation and maintenance practices in the FM of office buildings from the Nigeria context, aimed to address issues concerning activities of operation and maintenance. It also intends to reveal the adoption of FM techniques and associated challenges in the office buildings in Lagos., Nigeria. A total of 216 members of the Nigerian Institution of Estate Surveyors and Valuers (NIESV) were sampled using purposive sampling techniques and their responses were analysed by descriptive statistics such as weighted mean score (WMS), severity index (S.I), and Kruskal-Wallis H test (KWT). The study found that the major FM activities that are mostly engaged include space management, power plant/electricity maintenance, waste management, lift maintenance, general cleaning services, routine maintenance, and water management. While the preferred FM technique is a blended approach (both the preventive and the corrective methods). The prominent challenges in their respective categories were design flaws and poor installation of equipment (technical); inconsistency in financing maintenance, and high cost of maintenance components (finance); weak standards and poor enforcement (administrative), indifferent attitude towards maintenance issues, wrong perception and lack of foresight (top management). The study concluded that the operations of the FM practice are still in their infancy stage and characterised by prominent challenges of technical, administrative, and finance. However, being a multi-disciplinary profession, the study suggests efficient collaborative effort can be strengthened by an institutional framework that encourages human capacity development and enhanced technology to foster sustainable facilities management practice in the country.

The study analyze waterfront regeneration in Niger Delta and the problems bedeviling regeneration of the waterfront settlements in Port Harcourt, with an objective of ascertaining the socio economic, land use and physical development characteristics of the waterfronts. It also identifies constraints militating against effective regeneration of the waterfront settlements and examines how effective were past efforts in addressing the problems of waterfront has been. Data were gathered from owners of buildings and heads of households in the various selected waterfront settlements using Cluster sampling to group the settlements based on their location while simple random sampling technique was used to select seven waterfront settlements with the use of questionnaire and personal interview. Data were analyzed using simple frequency counts and percentages for the research questions. Findings reveals that the major constraint to waterfront regeneration was the fear of losing their houses, and failure of successive Governments to fulfill their promises, the preferred approaches for regeneration were transformation, complete clearance and revitalisation respectively. The study therefore suggest that Government should create a special purpose entity that will be responsible for the regeneration of the various waterfront settlements, the community should fully be involved in any regeneration project from the inception to the completion of the project and the government should draw up development plans with timelines for regenerating each settlement.

Contrary to the perception that estate surveyors and valuers are only concerned with the valuation of lands and buildings, their scope of work included art and artifact valuation. The valuation of art and artifacts can pose serious difficulties to a young valuer, as experienced valuers can establish expertise in the arts area. This study examines the possible challenges in the valuation of art and artifacts. Structured questionnaires were administered on 17 estate surveying and valuation firms in Abeokuta, Ogun State. The data was analyzed using the Relative Important Index. The results revealed that the valuation of art and artifacts requires more specialized knowledge and practical skills than what is required for valuing lands and buildings. The results further show that valuers are confronted with the challenges of a lack of information and inadequate access to past transaction records. This study recommends that, beyond the valuation of lands and buildings taught in schools, training on art and artifacts should also be incorporated in a curriculum and as well as professional training from time to time.
