Prequalification (PQ) is a significant process in the selection of private sector for the delivery of civil infrastructure projects.  But, the extant literature, for the most part, focused on PQ of construction projects.  The need for setting proper PQ, i.e., criteria and corresponding limits in public-private partnership (PPP) infrastructure projects, especially municipal solid waste (MSW) projects is still a lacuna in the body of knowledge of Indian PPPs.  To this end, this paper identified PQ criteria using content analysis of the sample of MSW projects. These identified criteria were subjected to regression modeling. These results were compared with the results of well-matured highway sector to draw comparison with MSW projects.  The practical implications are that urban local bodies (ULBs) are but less competent and less uniform in the rationale of setting the PQ criteria and limits.  This paper suggests that lowering the technical and financial PQ limits considering the market orientation will help in bringing more competitive bidders into the bidding.   Since MSW is in a very nascent stage of application of PPP, the study results could lay directions for future project procurement to discern right limits for right project sizes.

BIM is defined and used in several ways. As standardisation is now increasing on BIM, it is time to optimise the use of BIM, especially for civil infrastructure projects. The level of detail of the information produced and exchanged is not defined enough to allow production optimisation. It concerns a lot of processes and documents in the project, not only the BIM Execution Plan. It is proposed here to use system engineering principles to complete the BIM principle, helping to optimise the use of BIM. Some of these principles are similar but they have to be merged, regarding both System Engineering and BIM paradigms. Finally, integration of systems composing the civil infrastructure is the final aim. Using BIM and System Engineering principles in an efficient way is crucial to make BIM not a constraint but a need for the project.

There is a growing need for co-ordination of design, sustainability, economic and environmental aspects of infrastructure projects. The provision of civil infrastructure has a major impact on the natural environment and on the quality of life. A literature review conducted highlighted that infrastructure development was focused mainly on the financial and engineering aspects of projects. There is an urgent need to apply technologies and methods that deliver better and more sustainable performance of civil infrastructure as well as a need to establish a standard of measurement for greener infrastructure. The literature review revealed that the existing tools do not adequately rate and monitor civil engineering infrastructure design decisions from concept stage, through to detailed design and implementation. The objectives of the research were to identify green design technologies that can be used in township infrastructure and to encourage sustainable design on infrastructure township services, at various stages of the project. This would require the development of a green reporting system that incorporates environmentally friendly infrastructure design solutions. This study identified alternative eco-efficient civil infrastructure design solutions and developed sustainability criteria to analyse the eco-efficiency of infrastructure projects. The study proposed a Green Township Infrastructure Design Toolkit aimed at ensuring high-performance, eco-efficient, economical and environmentally friendly design decisions on stormwater, roads, water and sanitation related to township infrastructure projects. Various case studies were undertaken on a range of infrastructure projects to ensure consistency and reliability of the toolkit. Through a series of green reports, developed for each stage of a project, the toolkit measured the environmental efficiency of the design solutions. Recommendations suggest that engineering practitioners should endeavour to integrate greener engineering solutions into the traditional method of designing of infrastructure projects. The Green Township Infrastructure Design Toolkit with the use of its green reporting tools ensures the design of sustainable township infrastructure services, by progressively ensuring efficient, affordable, economical and sustainable provision of infrastructure services.
