## 4 Analysis of Results
### Analysis of Interview Feedback
#### 4.3.2 Interviewees' Feedback
However, no actual figures were given to substantiate the claims. * C/M BIM-I (2): For Question 4, only qualitative benefits were stated by the interviewee in that it saved time because it eliminated clashes and reworks. The informant added that it helped to facilitate collaboration amongst stakeholders. That was through easy access of project information and the virtual sharing of data. No quantifiable benefits were given, as the respondent cited difficulty in obtaining such data off hand. * C/M BIM-I (3): For Question 4, the informant cited qualitative benefits such as mobile/cloud BIM facilitates collaboration of the supply chain. Furthermore, the informant said that it creates an environment for understanding the project better. More importantly to them was that it makes collaborative planning of project work easier for its success. No quantifiable benefits were given. * C/M BIM-I (4): For Question 4, the interviewee stated that the qualitative benefits for mobile/cloud BIM technology in their organization are that it made it easier to monitor each panel's fabrication for the project. The informant added that it also helped them with inspections and planning project tasks easily. However, quantitative benefits were not stated even though the interviewee seemed to be of the view that the benefits were significant. * C/M BIM-I (5): In Question 4, the interviewee highlighted many benefits for using mobile/cloud BIM in their organization. The interviewee stated that the organisation has total control of all that happens in the project onsite without necessarily being onsite. All the communication done virtually gives them the ability to monitor and follow all project activities. The interviewee also highlighted a number of benefits such as: reduction in the number of site visits given the ability to view the project virtually; timing savings as queries and clashes were identified early and rectified before actual project construction. Quantitatively, the interviewee claimed that in one research project, 95% waste management was achieved due to reduced rework and minimised over ordering. While 80% was achieved post contract change, and because of the adoption of Navisworks, clash detection and visualisation were attainable. The interviewee stated that the models are shown to the client who instructs about variations before actual project construction, which saved time and cost, as well. Furthermore, it was noted that because of the design detail due to design thoroughness, therefore, there were less variations and unnecessary changes. Exact quantities are generated from the model in their organization using Bitcon software hosted by Elecosoft. Federated models are converted into Industry Foundation Class (IFC) files that were uploaded into the estimating software. The interviewee stated that the estimating software has a cost library, their historical cost data, Spons cost information and templates. The interviewee argued that ensured exact quantities were easily generated by a user-friendly system. Furthermore, the informant commented that project data were presented and displayed in a manner which made it easier for clients to read and understand. Although the quantitative benefits stated could not be corroborated by the literature, the interviewee seemed so confident so as to give the figures and was quite happy about being at the forefront of the new technology. Response to Question 5: Challenges and barriers you are aware of about mobile/cloud BIM use in construction site activities; in short, explain how these problems could be overcome? * C/M BIM-I (1): For Question 5, the interviewee stated a number of barriers and challenges of mobile/cloud BIM technology adoption. The interviewee was concerned about the temperamental mobile devices used, which are prone to damage given the harsh site conditions. The interviewee stated that the lack of security confidence for cloud-based systems was an issue. For example, a client like the Ministry of Justice has a protocol to use only their own verifiable systems.
