“…Information Communication Technologies (ICT) are achieving their core objective which is to deliver a ubiquitous environment within which everyone could conveniently retrieve and send information at any time and from any location (cloud computing). Hence, further research could be grounded on how cloud computing can e ectively and e ciently manage the huge volumes of data, such as by using Augmented Reality (AR) [8], Virtual Prototyping (VP) techniques [13], context-aware mobile computing [12,57], the Building Information Model (BIM) [20], hybrid integrated location tracking [68], simulations [67], real time simulators [69], BIM RFID model [70], the model view of the precast national BIM standard [71], BIM Augmented Reality [50], IFC for precast construction [72], and virtual prototyping tools [73]. However, several researchers are addressing this domain as the \CloudBIM" implementation will deliver the unconnected fragmented applications to more shared and dynamic networks which could have the features of automated task allocation [8,47,50].…”

Precast construction projects are associated with many activities, numerous parties, enormous e ort, and di erent processes. For e ective communication, this requires delivering appropriate and up-to-date information to enhance collaboration and improve integration. The purpose of this paper is to develop the system architecture and prototype of Context-Aware Cloud Computing Building Information Modelling (CACCBIM) for precast supply chain management. The ndings of this research are grounded on the literature of cloud computing, context-awareness, building information modelling, and, ultimately, the analysis of interviews with stakeholders in precast construction. Findings determine that lack of integration, improper planning and scheduling, poor production timing, poor coordination, lack of good communication among parties, wrong deliveries, and poor control and supervision are the major issues within the precast supply chain. These issues could result in adverse consequences for the objectives and success of the precast project. Eventually, to reduce and eliminate these issues, the proposed prototype will support appropriate deliveries, e cient monitoring, facilitation of coordination, and collaboration with improved communication. It is anticipated that this research will establish a unique perception in the precast construction industry, which will nally enhance its productivity, improve its e ciency, and maximise its e ectiveness.

“…Furthermore integrating such knowledge in a BIM system which enabling a knowledge-based approach to professional services. It is interesting to notice that some researchers are tagging IFC model as a semantic rich model [40][41][42], but others are claiming that IFC has insufficient semantic contained in the entity and relationships [43][44][45]. This conflict has been addressed by our framework.…”

Part 2: Organisational Semiotics and ApplicationsInternational audienceCost estimation is a dynamic and knowledge intensive process. Current practice of construction cost estimation is a process with fragmented knowledge. In order to have an integrated process, semantic should be modelled in respect to pragmatic. The investigation of BIM-based cost estimation confirmed that IFC can provide construction project semantics but incapable of relating domain semantics and pragmatics. In order to overcome this gap, we adopt organizational semiotics to fully reveal semantic units of cost estimation from a process perspective. Pilot study confirms feasibility of this approach. Future research will be a case study to collect all the instances for semantic units. Then semantic consistency and pragmatic implementation should be realized by the applications. This research highlights the importance of alignment between semantic (domain ontology) and pragmatic (meaning in use), it contributes also to identify a new approach of knowledge engineering for construction professional services under BIM environment

“…The lower three layers are to be studied initially-in order to illustrate the IT functionsafter which the upper three layers will be studied. It is interesting to note that some researchers have started to consider the IFC model as a semantically 'rich' model [45][46][47], however, others claim that the IFC is, in fact, insufficiently semantic [48][49][50]. This conflict will be addressed and considered as part of the framework of this study.…”

Producing a bill of quantity is a knowledge-based, dynamic and collaborative process, and evolves with variances and current evidence. However, within the context of information system practice in BIM, knowledge of cost estimation has not been represented, nor has it been integrated into the processes based on BIM. This paper intends to establish an innovative means of taking data from the BIM linked to a project, and using it to create the necessary items for a bill of quantity that will enable cost estimation to be undertaken for the project. Our framework is founded upon the belief that three components are necessary to gain a full awareness of the domain which is being computerised; the information type which is to be assessed for compatibility (syntax), the definition for the pricing domain (semantics), and the precise implementation environment for the standards being taken into account (pragmatics). In order to achieve this, a prototype is created that allows a cost item for the bill of quantity to be spontaneously generated, by means of the semantic web ontology and a forward chain algorithm. Within this paper, 'cost items' signify the elements included in a bill of quantity, including details of their description, quantity and price. As a means of authenticating the process being developed, the authors of this work effectively implemented it in the production of cost items. In addition, the items created were contrasted with those produced by specialists. For this reason, this innovative framework introduces the possibility of a new means of applying semantic web ontology and forward chain algorithm to construction professional practice resulting in automatic cost estimation. These key outcomes demonstrate that, decoupling the professional practice into three key components of syntax, semantics and pragmatics can provide tangible benefits to domain user.
