Item BIM Awareness and Adoption by Construction Organizations in Nigerian(Faculty of Engineering, University of Ilorin, 2018) Amuda Yusuf, Ganiyu; Adebiyi, R.T; Isa, Bala MuhammadBuilding Information Modeling (BIM) processes is gaining ground in the construction industry especially in the developed countries. Similarly, the professionals in developing economies such as Nigeria are expected to braise themselves with the current trend knowledge acquisition such as BIM. To ensure adequate planning for the construction industry adoption of BIM by professionals in Nigeria, it is important to determine the current level of awareness and adoption of BIM in the industry. Questionnaire survey was administered to construction industry practitioners to elicit information about their level of awareness and application of BIM. Descriptive analysis was used to analyze data collected from the survey. It has been established that the size of organization has effect on the transmission of information and knowledge from one level to another. As such the variables used in the analysis are the size of organizations‟, organizations turnover and industry professionals. Results of data analysis shows that the traditional Design-Bid-Build approach is still the most common approach and significant differences exist in the level of BIM utilization for projects among the professional group. Similarly, the design information exchange format utilized by various organizations varied based on the size and turnover of organizations. On the level of awareness and understanding of BIM, the results shows that the size of organisations influences level of awareness and understanding of BIM among respondents.Item Organizational performance measurement of Nigerian indigenous contractors using key performance indicators(Faculty of Environmental Design, Ahmadu Bello University, Zaria-Nigeria, 2019-11) Rasheed, A.S.; Adebiyi, R.T; Olowa, T.O; Musa, N.AMeasuring organizational performance of construction firms with project level Key Performance indicators (KPIs) is the norm in Nigerian construction industry like in many other countries. This has been found inadequate to measure overall performance of construction firms hence KPls measured at organizational level are necessary rind already relevant to contracting firms in several countries. Nigerian Indigenous Contractors (NICs) are largely assessed through project level KPIs and this has contributed to below average organizational performance resulting in close down of many firms and difficulties in delivering large construction projects. Current studies into KPIs on competitive advantage, but the NICs lack KPI¢ that address the peculiarities of the industry in the global front have helped construction firms shape performance strategies and enhanced their Nigeria. This study critically examines KPIs at organizational level of NICs. Through literature review, 75 KPIs were synthesized and used. Factor analysis was used to reduce the KPIs to 53 separated into ó measurable factors. Structured questionnaire was administered to a sample of 486 construction firms obtained from a population of 1669 firms in Abuja, Lagos and Rivers, 256 were returned representing 53% response rate. Factors were ranked using mean and standard followed by business procedure and financial which equally ranked high at 5.94 and 5.79 deviations. Results revealed Procurement factors ranking highest with an average mean of 5.98, respectively. Other factors identified include organizational knowledge and project management factors with means of 5.72 and 5.43 respectively, while environmental factors ranked lowest at 4.41. The study identified latent KPIs relevant jor measurement of organizational performance in NICs. The study concluded that the KPIs identified are organizational performance of NICs considering the high mean scores (above 4.41) of derived significant indices for measuring factors. It is recommended that NICs include these measurable indices for adequate assessment of their organizational performance.Item Quantity Surveying Practice and Evolution of SD Building Information Modelling(College of Engineering and Environmental Studies, 2016) Adebiyi, R.T; Babalola, M.O.; Amuda Yusuf, GaniyuManual quantification by Quantity Surveyors (QS) from two dimensional drawings is complex and prone to human error because of technological and organizational problems. Building Information Modelling (BIM) is an emerging technology with potentials for automation of quantity take-off and estimating process. This study examines barriers to five dimensional (5D) BIM adoption by Nigerian QS. Purposive sampling approach was used to administer questionnaire to practitioners in construction, consulting and clients' organizations in Nigeria. A total of 53 validly completed questionnaire were returned and analyzed using Statistical Package for Social Sciences. The five most important barrier factors to 5D BIM adoption by QS are: lack of collaborative initiatives from industry stakeholders; problems of communication and data sharing among firms; lack of government support and clear roadmap for BIM implementation; BIM model is not compatible with traditional take-over estimating software tools; and non-alignment of current rules of Building and Engineering Standard Method of Measurement. The 5-dimensiona/ BIM have tremendous potentials to increase the communication efficiency and interpretation ability of quantity surveyors. However, there is need for construction industry stakeholders to formulate strategies to develop and implement information exchange system that can support collaboration.
