AbstractElements that constitute the built environment are vast and so are the independent systems developed to model its various aspects. Many of these systems have been developed under various assumptions and approaches to execute functions that are distinct, complementary or sometimes similar. Furthermore, these systems are ever increasing in number and often assume similar nomenclatures and acronyms, thereby exacerbating the challenges of understanding their peculiar functions, definitions and differences. The current societal demand to improve sustainability performance through collaboration as well as whole-system and through-life thinking is driving the need to integrate independent systems associated with different aspects and scales of the built environment to deliver smart solutions and services that improve the well-being of citizens. The contemporary object-oriented digitization of real-world elements appears to provide a leeway for amalgamating the modelling systems of various domains in the built environment which we termed as built environment information modelling (BeIM). These domains include architecture, engineering, construction as well as urban planning and design. Applications such as building information modelling, geographic information systems and 3D city modelling systems are now being integrated for city modelling purposes. The various works directed at integrating these systems are examined, revealing that current research efforts on integration fall into three categories: (1) data/file conversion systems, (2) semantic mapping systems and (3) the hybrid of both. The review outcome suggests that good knowledge of these domains and how their respective systems operate is vital to pursuing holistic systems integration in the built environment.

Building Information Modelling (BIM) proves to be the most urgent trend in construction for the last years. Still the major part of this issue is dedicated only to the first stages of building lifecycle: design and construction. This article goal is to provide a critical overview on recent achievements in BIM application for the different steps of building lifecycle as well as ongoing digitalization of facility management. The paper explores the importance of applying mathematical modelling and multicriteria analysis such as Analytical Hierarchy Process (AHP) and fuzzy logic in management of built environment and provides recent examples of such applications consequently exploring its potential. Method of analysis in this article is horizontal analysis of publication activity in related research topic. Different levels of digital built environment are considered: from building (BIM) to the whole city (GIS). The result of the research reveal that emergence of scan-to-BIM technology brings benefits not only for the buildings which are designed with BIM models (current situation in the market) but for the buildings which are already built (as-built BIM).

Abstract The construction industry has often been described as stagnant and out-of-date due to the lack of innovation and innovative work methods to improve the industry (WEF, 2016; Ostravik, 2015). The adoption of Building Information Modelling (BIM) within the construction industry has been relatively slow (Cao et al., 2017), particularly in the South African Construction and Built Environment (CBE) (Allen, Smallwood & Emuze, 2012). The purpose of this study was to determine the critical factors influencing the adoption of BIM in the South African CBE, specifically from a quantity surveyor’s perspective, including the practical implications. The study used a qualitative research approach grounded in a theoretical framework. A survey questionnaire was applied to correlate the interpretation of the theory with the data collected (Naoum, 2007). The study was limited to professionals within the South African CBE. The study highlighted that the slow adoption of BIM within the South African CBE was mainly due to a lack of incentives and subsequent lack of investment towards the BIM adoption. The study concluded that the South African CBE operated mainly in silos without centralised coordination. The BIM adoption was only organic. Project teams were mostly project orientated, seeking immediate solutions, and adopted the most appropriate technologies for the team’s composition. The study implies that the South African CBE, particularly the Quantity Surveying profession, still depends heavily on other role-players in producing information-rich 3D models. Without a centralised effort, the South African Quantity Surveying professionals will continue to adopt BIM technology linearly to the demand-risk ratio as BIM maturity is realised in the South African CBE.

Literatures have proven a substantial increase in the awareness of Building Information Modelling (BIM) among built environment professionals in developing countries like Nigeria. However, the shortage of BIM competent professionals remains a significant challenge to the full utilization of this innovative construction process. These competencies deficiencies are in no small measure the catalyst for reduced productivity and the obsoleteness of recent construction graduates upon their emergence in the innovative construction world. This necessitate the need to assess the competencies of built environment professionals in the use of Building information modelling (BIM) with a view of suggesting strategies for improvement. The study mainly adopted an electronic questionnaire survey approach, which was targeted at built environment professionals in Abuja, Nigeria. Percentages, mean item score, relative importance index, and gap analysis were employed for the analysis of data. The study found out that built environment professionals in Abuja have a competency gap of 39% with an average possession of Administrative and Managerial BIM competencies and a high deficiency in Technical, Operational and Implementation competencies which are most required. Vocational training is currently most adopted for bridging these gaps. More so, the most effective strategies to improve the competency level of built environment professionals in the use of BIM are established to be: Attending BIM seminars, workshops, Trade shows, and Event; Enrolling for BIM software training and Incorporation of BIM into the Academic curriculum of higher institutions. This research will be needful in providing construction stakeholders as well as built environment educators with essential knowledge of the core competencies required as they develop and implement various BIM content in their domain.

The Impact

Architectural technology practice in Nigeria is influenced on the one hand by the drive to adopt technologically advanced techniques aimed at providing solutions to the existing challenges within the built environment, and on the other hand by constantly emerging socio-economic variables associated with high population growth, urban migration and resultant housing demands. From the outset of the drawing proposal to the entire lifespan of buildings, innovative developments in building information modelling (BIM) have enabled architectural technologists attain sustainable feats in the building industry. This study examined the curriculum for BIM training in polytechnics domiciled in Southeast Nigeria and the impact on sustainable development practice within the region. Sixtythree (63) architectural firms and three (3) polytechnics were randomly selected for this study. The survey research design was adopted in this study: two sets of structured questionnaires were administered to architectural technology graduates and their employers. 130 copies of questionnaire were administered to graduates of the institutions. The study revealed that 96% of the graduates had acquired some level of BIM proficiency; 56% acquired it from school, while 40% indicated it was acquired in practice after graduation. The result of correlation analysis showed that correlation between practice performance of technologists and proficiency in BIM is significant (p<0.01). The results of regression coefficients showed that proficiency in BIM had significant correlation with practice performance of the graduates. The study showed that course contents for courses in computer application did not extensively provide opportunities for graduates to acquire relevant skills. A robust review of the curriculum is needed to produce technically efficient technologists that can tackle the demands of the built environment for sustainable development to thrive.
