Managing Project Community in Infrastructure Megaprojects
Developing countries, such as India, look towards massive investments in infrastructure
megaprojects to achieve their development goals quickly. However, megaprojects are plagued with
failures and inefficiencies often due to the project’s inability to handle external stakeholders such
as project community. Project communities are the end users of the project, are most
inconvenienced by the project, and they hold significant potential to stop the project by asking a
democratically elected government to do so. In this context, we seek to understand how a metro
rail megaproject in India manages their project community through visible and invisible strategies
using an in-depth case study. The organizational power theories of the dimensions of power theory
and the circuit of power theory are used to explain these strategies. The research draws on data
from 30 semi-structured interviews with the project team and five years of social media data
comprising 640 Tweets. A Grounded theory method is used to find the visible, invisible strategies
and their relation between each other. The results show that invisible strategies depend on visible
strategies by relying on the adaptations made for the community and the visible strategies depend
on the invisible strategies by relying on the changed preferences of the project community. The
findings have contributions to theory and practice of managing project community in infrastructure

Systems Thinking Using SSM and TRIZ for Stakeholder Engagement in Infrastructure Megaprojects
Infrastructure megaprojects straddle multiple stakeholder boundaries who have an interest in the project and are affected by the project. Multiple papers in the literature stress the need for holistic approaches to stakeholder engagement, as existing approaches only address the concerns of the noisy stakeholders. This research proposes an innovative approach in which Soft Systems Methodology (SSM) is used for understanding stakeholder concerns, complemented by the use of Theory of Inventive Problem Solving (TRIZ) for identifying innovative solutions to address conflicting stakeholder goals. The researchers simulated the stakeholder engagement of the Coimbatore metro rail project, in India, through a workshop setting in a classroom to check the feasibility of this approach for stakeholder engagement. The 15 participants of the workshop were divided into four groups representing different stakeholders of the project. Data was collected through participant observations by the authors and oral feedback from the participants. The results show that while SSM helped to capture the concerns and goals of each stakeholder, TRIZ helped to identify and dissolve conflicts among these goals through innovative solutions. The theoretical, practical and pedagogical contributions are highlighted
Microgrid cost optimization: a case study on Abu Dhabi
This paper presents a microgrid cost optimization study specifically focused on the United Arab Emirates (UAE) based on the Genetic and Ant-Bee Colony algorithms. The main objective of the paper is to identify size and amount of power supply sources in Microgrids that result in minimum cost. Specific parameters pertaining to the UAE were employed within the new objective function and constraints. Two different scenarios were tested, and their results have been discussed. During this study, it was evident that solar-PV systems were the second most cost-effective way to reduce cost of microgrids preceded by micro-turbines
4D visualization to bridge the knowing-doing gap in megaprojects: an Australian case study
The literature on megaprojects are oriented towards ‘knowing’ the problems and ‘knowing’ the solutions, and there is a dearth in literature aimed at explaining strategies adopted in ‘doing’ or implementing that knowledge. Particularly, the literature highlights communication as important as part of the ‘knowing,’ while there is a gap in ‘doing,’ as performance improvements are still not evident. This research aims to explore how this knowing-doing gap in the communication of risk information was addressed by using 4D visualization. This article discusses the vent facility of a megaproject in Australia as a case study to illustrate the innovation. The 4D model developed for the facility helped the project team to visualize the construction of a critical part of the project, discuss the construction methodology, identify the risks in the construction process and persuade the non-technical decision-makers of the project to take appropriate action. The risks identified through the visualization covered safety, program, and interface risks. This study offers insights into the role of visualization in bridging the knowing-doing gap in the construction industry in the context of a megaproject.</jats:p
TIRSPEC : TIFR Near Infrared Spectrometer and Imager
We describe the TIFR Near Infrared Spectrometer and Imager (TIRSPEC) designed
and built in collaboration with M/s. Mauna Kea Infrared LLC, Hawaii, USA, now
in operation on the side port of the 2-m Himalayan Chandra Telescope (HCT),
Hanle (Ladakh), India at an altitude of 4500 meters above mean sea level. The
TIRSPEC provides for various modes of operation which include photometry with
broad and narrow band filters, spectrometry in single order mode with long
slits of 300" length and different widths, with order sorter filters in the Y,
J, H and K bands and a grism as the dispersing element as well as a cross
dispersed mode to give a coverage of 1.0 to 2.5 microns at a resolving power R
of ~1200. The TIRSPEC uses a Teledyne 1024 x 1024 pixel Hawaii-1 PACE array
detector with a cutoff wavelength of 2.5 microns and on HCT, provides a field
of view of 307" x 307" with a plate scale of 0.3"/pixel. The TIRSPEC was
successfully commissioned in June 2013 and the subsequent characterization and
astronomical observations are presented here. The TIRSPEC has been made
available to the worldwide astronomical community for science observations from
May 2014.Comment: 20 pages, 21 figures, 2 tables. Accepted for publication in Journal
