    Challenges of transcending BIM information from design phase to real time on-site construction phase
    (Ceylon Institute of Builders, 2017-06) Wijewickrama, MKCS; Jayasena, HS; Ariyachandra, MRMF; Sandanayake, YG; Ramachandra, T; Gunatilake, S
    Building Information Modelling (BIM) is a revolutionary paradigm which espouses modernization and innovativeness to the conventional Architecture, Engineering, Construction and Operations (AECO) industry. Successful BIM model is enriched with information which was congregated during design phase and such information should be circulated throughout the project life cycle without disturbing its originality. Nevertheless, when the complete BIM information is transferred to the site office, the on-site personnel are not absorbing the real essence of effective BIM information for on-site construction activities. Improvements in Mobile Computing Technology (MCT) have succeeded in linking this communication gap through forms of electronic pocketbooks, personnel laptops and Personal Digital Assistants (PDA). Even though, there is a greater push from technology, site personnel are not willing to accept it and they still prefer the traditional procedure. This discloses that site personnel are not prepared to practice such technologies due to their nature of Resistance to Change (RTC). Subsequently, the aim of the research is to identify the challenges of transcending BIM information from design phase to real time on-site construction phase. To accomplish the aim, a qualitative research approach was followed, steering semi-structured interviews. The gathered information was analysed rigorously through computer based content analysis. This topical study manifest that, all the recognized resisting factors extensively challenge the transcending of BIM information to the on-site construction phase. Hence, the research has successfully identified the challenges which barricade the transcending of BIM information to real time on-site construction phase.

    Procurement system selection model for the Sri Lankan construction industry
    (Ceylon Institute of Builders, 2017-06) Chanudha, RAC; Disaratna, PAPVDS; Anuruddika, SMN; Ariyachandra, MRMF; Sandanayake, YG; Ramachandra, T; Gunatilake, S
    Construction procurement system involves processes of acquiring services and products for the project activities starting from investigation up to the completion. With the development of new concepts and technologies, construction procurement arrangements have also advanced. Erroneous selection of a procurement system usually leads project to failure. Although, several procurement selection tools have been developed to minimize the adverse effect of overwhelmed wrong selections, those tools are not widely used in Sri Lanka (SL). Hence, it is vital to propose a new Procurement System Selection Model (PSSM) which can overcome barriers of existing PSSM. A qualitative approach was used to identify prevailing practices and barriers to practice existing selection methods. Decision charts were developed by assigning average utility values for functional grouping, payment method and pricing mechanism. Accordingly, the preliminary procurement system selection framework was arranged which includes seven steps namely; appoint an independent advisor, identification of project brief, identification and prioritizing factors affecting selection of procurement selection, choose functional grouping and payment modality, presentation of options found in step four in ascending order, selection of procurement strategy by the client and selection of parties involved in the project. Ultimately, proposed PSSM in this study merge the existing selection procedure in SL in a manner that leads selection into its best position. The study further recommends timely modernization of decision charts with Average Utility Value (AUV) and procurement systems, since suitability of each procurement system to selection criteria may change with development of construction industry.

    Software capabilities of Sri Lankan architectural professionals for BIM adoption
    (Ceylon Institute of Builders, 2017-06) Kumara, EKAS; Jayasena, HS; Ariyachandra, MRMF; Sandanayake, YG; Ramachandra, T; Gunatilake, S
    Building Information Modelling (BIM) is a technological and attainable concept, which has upgraded the construction industry into a more diligent industry. It has globalized in a way, which make innovative, cost effective, energy efficient, sustainable and practicable products as well as faster and more effective processes. By the aid of various BIM software packages connected with different disciplines for various stages, this realisation could achieve more accomplishments. However, majority of practitioners of the construction industry only have competencies over the traditional software and this is also one of the major constraints for not applying BIM to the construction organizations. Therefore, construction practitioners must have proficiency over the competencies required for effective BIM products. Interestingly, there seems that many BIM tools have similarities to conventional tools. Software developers over the world have developed several BIM software tools for each of the disciplines which are currently involved in the projects. Majority of the recently completed BIM assignments have typically used software suites belonging to Autodesk software developers, as such there is high potential of using such suits in early BIM projects in Sri Lanka. Hence, this study aims to identify extent to which BIM like activities in conventional tools are practiced in the Sri Lankan industry. It synthesizes the findings of a literature review on software disciplines which are used in the BIM implementation by various professionals in each of the stages of project sequence. Through the desk study and the expert interviews a qualitative study conducted to identify the gap between 3D BIM modelling competencies with the current competency level of the Sri Lankan Architect. It was found that, working in Revit is more like building a building than drawing one. Further, the great thing about Revit is that all the objects work not the same as in AutoCAD. So if designer know how to place a wall in CAD, but designer can’t place a wall in Revit. Because it use object oriented method. Fundamentals are just about the same, there are of course a few differences but can work through those fairly easily. According to the summary, can be concluded that Sri Lankan Architects much familiar about few of the task. But, the handling/performing such activities much differ than what they follow.
