“…The research results show that the existing relationship is a moderate correlation with a substantial relationship based on the value r = 0.5260, which means that organizational paradigm changes regarding BIM are very important for maximum implementation of BIM in construction projects. The same thing was conveyed by [31] that BIM adoption and implementation at an organizational level can result in enhanced efficiency and reduction of errors and de-duplication of tasks because of the ability to foster greater collaboration between project stakeholders and departments, to integrate building systemsresolve conflicts and software interoperability. Further, BIM adoption at the organizational level can result in a positive return on the investment mostly generated through savings reduced project costs [6].…”

The future of BIM is exciting and full of challenges, but there are several obstacles to implementing BIM effectively in the construction sector in Indonesia. Thus, the aim of this research is to examine the challenges of implementing BIM on construction projects, especially in Indonesia. Data was obtained from 45 respondents who answered questionnaire questions, including owners, consultants, contractors/subcontractors, private companies and state-owned enterprises representing construction parties in Indonesia. Empirical analysis using the Correlation Coefficient-A Measure of Linier method states that there are seven variables which are challenging variables in implementing BIM in construction projects. The seven challenge variables are BIM technical readiness, organizational paradigm changes regarding BIM, work environment awareness of BIM, compliance on BIM rules, increased competency and skills, consistent application of effective leadership, maturity of BIM utilization. These seven challenge variables have a linear relationship with the application of BIM in Indonesian construction projects. In conclusion, construction project parties in Indonesia must responses positively to these seven challenges to ensure that the implementation of BIM in construction projects in Indonesia is in accordance with the regulations released by the government.

“…The use of 3D digital sketching is so far limited to the recording of purely graphical design intentions, which diminishes its benefits in the context of a semantically rich profession of architecture. The issue is reinforced by an increasing need to communicate and perform multiple project functions simultaneously, even in early stages of design (Glick and Guggemos, 2009). The feasibility achieved through the application of the IFC schema motivated this research to base the proposed workflow on a small scope of graphical and nongraphical IFC definitions for the description of conceptual BIM models.…”

The preliminary development of highly detailed BIM models lacks eligible design methods in the conceptual design stage. Initial design solutions cannot be shared among collaborative and consecutive design parties without relying on error-prone briefings and data exchanges. As advances in Artificial Intelligence are increasingly being used for BIM's big data challenges, this paper presents a workflow based on a small scope of IFC definitions for the generation of conceptual BIM models from 4D semantic sketches, using a machine learning based pipeline. The workflow offers a user-friendly architectural design perspective, while preserving information more reliably throughout the entire life cycle of a BIM model.

“…This could have significant implications for new and existing UK building stock (much of which is older than 20 years) where non-potable demands can account for approximately 30% of domestic water use, reaching over 60% for commercial users (Karpiscak et al, 1990). Accounting for the operational and embodied energy of any conventional GW system is relatively unexplored, except for a few notable publications (Environment Agency, 2008Glick et al, 2009;Harnett et al, 2009;Memon et al, 2007). Moreover, for the shared GW system suggested by Zadeh et al (2010), this is completely unexplored.…”

Urbanisation in the twenty-first century is accompanied by higher water demands per unit area of available space.The ability of water providers to meet these demands long term will require sustainable innovations in terms of water supply. Previous research by the authors has shown that urban mixed-use systems that share greywater (GW) between high-rise domestic dwellings (where GW production exceeds non-potable demands) and high-rise offices (where non-potable demands exceed GW production) could overcome these difficulties. This paper explores the carbon costs (embodied and operational) of such an urban arrangement by investigating the influence of membrane bioreactors (MBRs), constructed wetlands (CWs), building heights, floor plate areas and cross-connection distances.Five water supply scenarios are considered: scenario 1 (conventional mains treated offsite); scenarios 2a and 2b (individual GW treatment via CW/MBR); scenarios 3a and 3b (shared GW treatment via CW/MBR). Over a 15-year period it is shown that shared CW treatment had the lowest carbon dioxide emissions, saving up to 11% compared with conventional mains, whereas a shared MBR increased carbon dioxide emissions by up to 27%. Furthermore, most carbon dioxide savings occur when the ratio (height or floor area) of office building to residential building is 2:3.
