Building Information Modelling (BIM) is the process of creating digital parametric models for life cycle data management. Use of parametric modelling tools enables in integrating the building data from various stakeholders, on a virtual platform. On large-scale building projects with numerous stakeholders, a well-drafted strategy for BIM adoption becomes essential. This can be attributed to the complexity in the information exchange process between the various stakeholders. This paper focuses on investigating the strategies for BIM adoption in the Indian Architecture, Engineering and Construction (AEC) industry. What are the typical BIM goals on a project? What strategies can lead to effective BIM adoption? These are questions that this paper seeks to address. Case based investigation was carried out in three commercial building projects of comparable scale. A detailed investigation of the cases was carried out through interviews with the various stakeholders and documentation of the BIM adoption process. Case data were analysed to identify the strategies commonly adopted on projects. Further analysis enabled in developing a framework for BIM adoption strategies in the Indian AEC industry.

Stakeholders’ perception on project uncertainty in ppp Projects in India
(Ceylon Institute of Builders, 2018-06) Nair, CP; Mahalingam, A; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
PPP projects are often complex, unique and dynamic due to high sunk-in costs and long concession period making it vulnerable to risks (known-unknowns) and uncertainties (unknown-unknowns). Previous researches focus on risks associated with PPP projects. But these projects are hit by uncertainties which surfaces as turbulences during the execution as well as the operation stage of the project. The extant literature does not focus much on the uncertainties manifested in these projects nor does it convey the stakeholders’ outlook on uncertainties, which has a strong bearing on project management. In order to ensure sustainability of PPP projects, among other factors, it is important to identify uncertainties that affect their performance in various phases or leads to uncertain situations. A superset of uncertainties identified from literature was subsequently expanded and validated by PPP Experts. Stakeholders perceptions on the fifty-four identified uncertainties likely to manifest in various phases was assessed through a survey to identify and evaluate the uncertainties that affect the implementation of transport PPP infrastructure projects as well as explore the perception of stakeholders on project uncertainties for endto- end sustainability. Differences in opinion among stakeholders on uncertainties often are found to act as a hurdle for effective implementation of PPPs. It is comforting to note that stakeholders have arrived at a general understanding on uncertainties since the inception of PPP projects in India, though there is long way to go. The comprehensive list of the uncertainties brought out in this paper validated by the experts in this field through their experience gained in managing PPP projects in India over the past two decades, when given due consideration while developing Concession Agreements in future will help to institutionalise addressing these unknown unknowns as well as keep the project officers prepared to effectively manage them as and when they unfold.

Towards digital delivery of metro-rail projects in India
(Ceylon Institute of Builders, 2018-06) Senthilvel, M; Soman, RK; Mahalingam, A; Whyte, J; Raphael, B; Brilakis, I; Varghese, K; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
There is a large programme of metro-rail construction in India, upgrading public transportation systems to provide rapid transit to millions of people in major Indian cities. The scale of this development makes it important to innovate as improvements in design, construction and operations can have a significant impact on built asset sustainability. As integrated digital delivery approaches are becoming used internationally in infrastructure projects, new questions arise about their application and suitability in these Indian metrorail projects. This paper is based on a research collaboration involving desk-based study, site visits, and a hosted workshop with 40 participants including client representatives of six major Indian metro-rail projects along with technology providers and delivery teams. Findings are that - while Nagpur Metro project is most advanced in implemented Building Information Modelling (BIM) in its planning and design phase, translating practices from Crossrail in London into the Indian context - there are significant challenges in adopting digital practices in the delivery of new transportation schemes in Indian cities. These challenges include stakeholder awareness and education; integration and interoperability; standardization; cost implications and BIM strategy. The paper concludes with some potential directions for future research and discusses the potential for India to ‘leapfrog’ a generation of technology to implement low-cost effective digital solutions.
