    A study of Mentoring in Real Estate Practice in Northwestern Nigeria
    (Department of Estate Managment, Falculty of Environment Design and Management, Obafemi Awolowo University Ile-Ife Nigeria, 2023) ISHAYA, David Ayock
    This study examined the profiles of estate surveying and valuation (ESV) firms in Northwestern Nigeria as well as the skills and competencies lacking of employees in ESV firms in the study area; assessed the mentoring strategies employed by ESV firms in the study area; analysed the effectiveness of the mentoring strategies; and determined the factors influencing the effectiveness of the mentoring strategies employed by the ESV firms in the study area. These were with a view to providing information that could enhance real estate practice. Primary data was employed for the study. The data was obtained from ESV firms practicing in Kano and Kaduna states using a mixed research method involving the use of questionnaires and interviews. A total enumeration survey was carried out on all the 40 and 80 ESV firms in Kano and Kaduna states respectively. Interviews were conducted with three senior surveyors in Kano and seven in Kaduna states. Data collected from the ESV firms included their profiles, mentoring strategies, employee skills and competencies and factors influencing mentoring effectiveness. The information obtained were analysed using frequency and percentage, mean rating, standard deviation, Analysis of Variance (ANOVA), independent t-test, and Principal Component Analysis. The findings showed that the employees were mostly HND holders (47.01%), while 98% of the respondents were male. More so, majority of the respondents held senior managerial positions with 21% and 84% being Head of Departments Kaduna and Kano states respectively. The results further showed that based on a 5-point Likert scale, risk-taking propensity (MS = 3.64) is the most ranked skills and competencies lacking among employees in ESV firms. Traditional mentoring with response frequency of 88.6% and 92.0 % in Kaduna and Kano states respectively was found as the predominant form of mentoring adopted by ESV firms in the study area. The mentoring strategies adopted by ESV firms xi, xii differed. In Kaduna State, the most commonly employed strategies were encouragement, feedback and participation with mean scores of 2.96, 1.64 and 3.25 respectively; whereas in Kano State, the most used mentoring strategy was conversation (MS = 4.78). With mean scores of 4.74, 4.70, 4.48, 4.30, and 4.17, building trust, emotional support, orientation, experience sharing, and encouragement respectively were the most effective forms of mentoring strategies employed by ESV firms in the study area. Using principal component analysis, the major determinants of the effectiveness of mentoring by the ESV firms are cultural beliefs, individual traits, and the gender of both mentors and mentees with mean scores of 3.26, 3.69 and 2.78 respectively. The study concluded that mentoring in real estate practice in the study areas is not formalized and that its effectiveness is greatly influenced by cultural beliefs, individual traits, and gender factors.

    BUILDING INFORMATION MODELING USAGE AND PROJECT STAGES INTERFACE AMONG CONSTRUCTION PROFESSIONALS IN LAGOS STATE, NIGERIA
    (DEPARTMENT OF BUILDING, FACULTY OF ENVIRONMENTAL DESIGN AND MANAGEMENT, OBAFEMI AWOLOWO UNIVERSITY, 2022) ADEBOWALE OLUWAYINKA ADEFEMI
    This study examined the extent of building information modelling (BIM) usage among construction professionals, determined the interface problems in construction project stages among professionals and investigated the impact of BIM usage on professional’s interface at stages of construction projects in Lagos State, Nigeria. These were with a view to providing information that could enhance project delivery. Primary data were used for this study and obtained through structured questionnaire. The target population was construction professionals who had substantial knowledge of BIM usage and who had experienced interface problems at the design and construction stages of projects in Lagos State. A total of two hundred and sixty (260) copies of completed questionnaire were retrieved through online and physical administration using snowball sampling technique for selection of respondents. Data were analysed using frequency, percentages, exploratory factor analysis, confirmatory factor analysis and structural equation modelling. Findings revealed that more than 70% of the respondents had less than six years’ experience with BIM usage, 36.5% of the respondents had employed BIM for private projects, 48.5% for public-private projects and majority of the construction professionals use BIM mostly for building projects (90%) and design-build procurement method (57.2%). Over 60% of construction professionals had either very low, low or fair level of competency in respect of BIM usage. On the proficiency level of BIM usage, about 86.5% among the professional members were either skilled or semi-skilled. The overall satisfaction level in using BIM for project work was 74.2% among the project members which shows that a majority of them were satisfied with BIM usage. The major interface problems at the design stage in the study are badly written contract (C15); excessive amendments when changes occur in designs (C16) (DIP5=0.794); lack of stipulated data (C4) (DIP1=0.744); and design complexity (C9) (DIP4=0.743). However, the major interface problems at the construction stage are change order (C29) (CIP4=0.814); inadequate specialised quality-control team (C31) (CIP1=0.798); and poor quality of construction (C21) (CIP2=0.797). The impact of BIM on professionals’ interface at the design stage are producing tools for reporting task completion, quality value and mistakes of the design team (ID5) (IDS1=0.836); automatic low-level of amendments whenever modification occurs in design (ID14) (IDS2=0.794); and improve design quality (ID8) (IDS3=0.771). The impact at the construction stage includes enhanced site utilisation, space coordination and production data (IC4) (ICS3=0.788); enhanced quality control process on site (IC9) (ICS1=0.787); and minimised interface conflict through integration of construction simulation (IC18) (ICS2=0.774).

    Recreational Potentials of forest reserves in Nigerian a case study of eleyele forest reserve in Ibadan Oyo state, Nigeria.
    (Department of Urban and Regional Planning, Faculty of Achictecture, Obafemi Awolowo University., 1989) Ibitoye Temitope Olufemi
    Most Nigeria towns are short of recreational open space despite express demand and rising leisure pursuits by urban dwellers. In view of this, it is necessary to make a realistic assessment of how potential recreation resources can be developed for optional use. The use of forest reserves for recreation pursuits is one of the ways of relieving urban area in Nigeria which are grossly deficient in recreational forest reserves. There is evidence that urban dwellers informally use existing forest reserves for recreational purpose, especially those within reach of urban populace. To this end, this study examines the rationale and potentials of developing forest reserves to provide for recreational needs of urban dwellers in Nigeria with a case study of Eleyele forest reserve in Ibadan, Oyo Stste

    Assessment of Polyethylene Terephthalate Waste Carbon and Periwinkle Shells-Based Chitosan as Adsorbent for Trichloroacetic Acid removal from Water.
    (Institute of Environmental Control Management, Obafemi Awolowo University., 2022) ABIOYE Babasanmi Oluwole
    The study determined the physicochemical parameters and trichloroacetic acid concentrations of the water samples before and after conventional treatment at the Obafemi Awolowo University, Ile-Ife water treatment plant. It also investigated the adsorption efficiencies of chitosan modified and unmodified adsorbent prepared from polyethylene teraphthalate waste and periwinkle shells for the removal of trichloroacetic acids in the water samples.
