    Assessment of the usage of software packages by quantity surveying firms in southwestern in Nigeria.
    (Department of Quantity Surveying, Faculty of Environmental Design and Management. Obafemi Awolowo University., 2021) OLALEKAN, Yunus Olaitan.
    This study identified and examined the software packages used by Quantity Surveying firms in Southwestern Nigeria; evaluated the trend in the usage of software packages in the study area; assessed the drivers and barriers of usage of the software packages; and examined the impact of their usage on service delivery in the study area. These were with a view to enhancing service delivery. Quantitative survey research design was used to collect primary data for this study via structured closed ended questionnaire. The questionnaire was administered on quantity surveying firms in Lagos, Ondo and Oyo States which constituted the study population. Total enumeration was used for Ondo and Oyo States with six (6) and 15 (fifteen) quantity surveying firms, respectively. Out of the 127 quantity surveying firms in Lagos State, 64 (50%) were sampled using simple random sampling technique. Data were obtained on educational status, professional status, employment position, years of experience, age of firms, firm’s location, type of software used, level of usage of software packages, trend in the usage of software packages, drivers and barriers of the usage of software packages and impact of the usage of software packages on service delivery. The data collected were analysed using descriptive (frequency counts, percentages, and mean score) and inferential (regression analysis and Analysis of Variance) statistics. The results showed that AutoCAD with mean score (MS) of 2.8 in a 5-point Likert-like scale (0-4) was the most used software package by quantity surveying firms in the study area. The others were Microsoft Project (MS = 2.44), MasterBill (MS = 1.58), QSCAD (MS = 1.51) and Revit (MS = 1.37). The trend in the usage of software packages by the firms was most erratic (up and down patterns) in Ondo and Oyo States but relatively regular in Lagos State. It was also found that the five lead drivers of the usage of software packages were: changing trend in technology (MS = 3.56); flexibility of usage (MS = 3.22); corporate technology strategy (MS = 3.10); competition among QSFs (MS = 3.08); and competition among construction professionals (MS = 3.07). Similarly, the top five barriers to the usage of software packages were high cost of software packages (MS = 3.42); inadequate power supply (MS = 3.20); high cost of hardware (MS = 3.17); rate of virus attack (MS = 3.07); and inadequate job order to encourage software investment (MS = 2.92). The study also found that the usage of software packages has mostly impacted the preparation of bills of quantities with a mean score (MS) of 3.53, closely followed by project planning (MS = 3.51), estimating (MS = 3.47), cost planning (MS = 3.36) and cost analysis (MS = 3.24). The study concluded that the usage of software packages by quantity surveying firms in the study area was generally low and that high cost of software packages and inadequate power supply were mostly responsible for the low usage of software packages by quantity surveying firms in Southwestern Nigeria with consequent negative impact on service delivery.

    Impact of project governance on the performance of public private partnership projects in Lagos State, Nigeria.
    (Department of Building, Faculty of Environmental Design and Management. Obafemi Awolowo University., 2022) OLADELE, Tosin Emmanuel
    This study examined the governance structure, and evaluated the critical success factors of Public Private Partnership (PPP) projects in Lagos State, Nigeria. It also examined the challenges of the PPP projects governance and the effect of governance structure on the cost and time profiles of the PPP projects in the study area. These were with a view to enhancing projects delivery. The study made use of both primary and secondary sources of data. For the primary source of data, interviews were conducted with the key stakeholders/role players and questionnaire were administered on the professionals that were involved in the identified case studies. The secondary data were sourced from relevant departments of government, and from the concessionaires of the identified PPP Projects in the study area. Seven (7) completed PPP projects were used as case studies. A total of one hundred and twenty (120) professionals were sampled, which included sixteen (16) professionals from five (5) case study projects and twenty (20) professionals from two (2) case study projects. One hundred and twenty (120) questionnaire were purposively administered on the professionals, while 81 questionnaire were successfully retrieved, indicating a 68% effective return rate. The data obtained were analysed using Relative Importance Index (RII), Thematic Analysis, Importance Index IMPI), Severity Index (SI), and Cost and time Overrun Equations. The results showed that two forms of governance structures namely: departmental structures and new separate authority, were mostly adopted in the case study projects. However, lack of institutional frameworks for PPP during its early adoption in the study area resulted in the use of traditional procurement contracts in some case study projects, which lacked PPP contents. The result also showed that project accountability and responsibility (Mean Index = 0.82) was the most practiced project governance principle for PPP projects. Disclosure and Reporting (Mean Index = 0.70) was least practiced as it had the least mean index value. The major Critical Success Factors (CSFs) of PPP projects were, Knowing the project (IMPI% = 79.61); information and communication (IMPI% = 77.41); the support of principal officers (IMPI% = 76.91); capable project team (IMPI% = 72.33); value for money (IMPI% = 71.08); and strong dedication by public and private actors (IMPI% = 70.84). The Severity Index (SI) of the challenges of the PPP projects governance showed that the major governance challenges were Lack of capacity on the part of the concessionaire (SI% = 85.68); costly transactions (SI% = 85.18); high procurement costs (SI% = 84.45); fraud and bribery (SI% = 83.70); high project budgets and long execution periods (SI% = 83.45); and uncertainty of political environment (SI% = 83.21). The results showed that the adopted governance structures in most of the case studies caused delays on the projects. The study concluded that, the unavailability of institutional frameworks for PPP during the early adoption of PPP in the study area resulted in different forms of governance structures (Policies) for PPP projects and confirmed that the governance structures of most of the PPP projects caused delays, which significantly had adverse effects on PPP project deliverables.

    A documentation of styles in yoruba headites.
    (Department of Fine and Applied Arts, Faculty of Enivironmental Design and Management, Obafemi Awolowo University., 2021) FAJOBI, Janet Adeola
    This project document a visual representation of styles in Yoruba headties. This project is focused on the use of coloured wools stitches as embroidery techniques with gluing and sewing of fabrics on canvas to make a visual representation of gele styles in the 1980’s, 1990’s and the contemporary time. Data for this project was collected from both primary and secondary sources. Primary data was oral interviews with the Yorùbá elders about how headties were been tied in the 80’s, 19’s and now. The secondary source include project works of other people, internet publications, magazines, pictorial images online and journals. The process of executing this project includes: source for references, generating canvas size, sketching, stitching on the sketches image with different colour of thread, cutting of aso-oke to form the gele styles for each works, re-stretching and framing. The findings revealed that the Yorùbá indigenous hairstyles vary based on their importance and usefulness. These headties sometimes shows the importance of the wearer and it shows that has time evolves people explore different ways in which gele can be tied. Findings also showed that the headties are gradually taking new form day by day as western influence have been included to the styling of these headties. In conclusion, this project has been executed to form a visual reminder for the present generation and a historical record for generation to come. It also serves as a visual record of how gele has been presented in the past and how it has evolved till date. In a nutshell, this project, revives and retains the quality of Yoruba dress culture.

    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 project 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).153p

    Estate surveyors and valuers' perception of intellectual property valuation in Lagos state , Nigeria.
    (Department of Estate Management, Faculty of Enivronmental Design and Management , Obafemi Awolowo University., 2023) Ekpo, Immacuata Anthony.
    This study examined the levels of awareness and preparedness of Estate Surveyors and Valuers (ESVs) to carry out Intellectual Property (IP) Valuation in Lagos State, Nigeria; assessed the perception of ESVs on IP Valuation and determined factors affecting their perception on IP Valuation. These were with the view to ascertaining the prospect for the adoption of IP valuation in the study area. Primary data was used for this study. The data was sourced with the use of questionnaire from Estate Surveyors and Valuers in Lagos State. Lagos State was stratified into Lagos Mainland and Island to ensure proportional representation in the sample. From the 412 registered estate surveying and valuation (ESV) firms in the study area, 50% in each stratum was selected using the raffle draw approach to arrive at a sample size of 206 firms. In each ESV firm, questionnaire was administered at random to one Estate Surveyor and Valuer only. Also, in-depth interview was conducted with 3 members of the Business Asset and Intellectual Property Valuation Professional Group, and 4 members of the Estate Surveyors and Valuers Registration Board of Nigeria (ESVARBON). Data collected included profiles of ESVs, awareness of basic concepts relating to IP valuation, number of training and materials obtained to prepare for IP valuation, ESVs’ perception and factors influencing perception of IP valuation. The data was analysed using frequencies, percentages, mean ranking, relative importance index (RII), thematic and factor analyses, and Chi Square. The result of the study indicated that 87.6% of ESVs in Lagos State were aware of IP valuation. The level of awareness was average for majority (49.5%) of the ESVs and 23.9% actually had IP valuation experience. Also, it was found that 57.2% of respondents have attended at least a seminar/workshop in preparation for IP valuation. However, respondents agreed, on a five point Likert scale, that: “more seminar/workshop is needed” (mean=4.46); “more sensitisation is needed” (mean=4.41); “a dedicated MCPD on IP valuation is needed”(mean=4.39); and “a dedicated conference on IP valuation is needed” (mean=4.39). By implication, preparedness is still at sensitisation/awareness stage which is insufficient for the task ahead. Moreover, the result of factor analysis indicated that the respondents perceived IP valuation as: full of challenges with 37.65% variation explained; full of benefits to valuers (19.029%) and to SMEs (10.288%). Lastly, the results established that factors in the perceiver (ESVs), such as experience, benefits, interest, mood and familiarity with the target, contributed 61.241% variance and factors in the target (IP valuation), such as scarcity of data, complexity and assumptions (11.165%) affected ESVs’ perception of IP valuation. The study concluded that ESVs had positive perception of IP valuation but their preparedness was insufficient due to factors inherent in the valuation and in ESVs themselves; hence, more training is needed to hasten the adoption of IP valuation.
