Factors affecting public-private partnership preference in Indian municipal waste sector

The use of public–private partnership (PPP) approaches for developing infrastructure has been well recognized. The allocation of risk between public authority and private sector differs among the different types of PPP projects. The objective of the paper is to analyze the factors that influence the type of PPP and the performance of different types of PPP contracts.,A unique data set of 202 national highway PPP projects from India, comprising 154 toll and 48 annuity projects formed the basis of the study.,There are significant differences between toll and annuity PPP projects. The former are longer, are implemented in better developed states but are also characterized by higher cost over-runs. The latter are characterized by higher debt–equity ratio.,Mitigating revenue risk can significantly enhance the debt capacity of the projects, thereby reducing the overall cost of capital. To make toll roads attractive for bidders, they have to be developed as longer stretches. Toll projects that are immediately ready for development at the time of award would reduce cost overruns of toll projects and sustain the interest of private developers.,Comparison of toll and annuity PPP road projects has never been done previously. The unique data set used in this study highlights the differences in characterization and performance for both the project types. The study provides evidence support to “intuition” and enables policymakers to choose the right form of PPP to realize their objectives.

Comparison of toll and annuity PPPs: a case study of highway projects in India

PurposeThe purpose of this paper is to select a suitable procurement method for steel building construction in Sri Lanka following a systematic method which weigh, both procurement selection factors and existing procurement systems.Design/methodology/approachAn abductive research stance is followed in this empirical study. Procurement selection factors were selected through a critical literature review which was followed by a quantitative questionnaire survey. The collected data were analysed using descriptive statistical analysis and relative important index.FindingsThe critical literature review outlined 46 procurement selection factors, out of which 26 factors were very important in steel building procurement selection. Short construction period and higher constructability of design are ranked at the top with the highest priority rating factors. Management-oriented procurement system was selected as the most appropriate procurement system for steel building constructions within the Sri Lankan context.Research limitations/implicationsThe study is limited to widely use three procurement systems in Sri Lankan construction industry. Yet, the process followed in selecting the most appropriate procurement system could be applied for other contexts. The implications of the study are mainly identifying management-oriented procurement as the most suitable procurement method for steel building construction in Sri Lanka.Practical implicationsThe systematic procedure of procurement method selection for steel building construction may use in the Sri Lankan construction industry to limit the resource loss due to wrong selection of procurement.Originality/valueA study which critically and comprehensively presenting a procurement selection process for steel building construction is not recorded in Sri Lanka prior to this study.

Selecting suitable procurement system for steel building construction

The public–private partnership (PPP) based model for the execution of infrastructure projects originated from Anglo-Saxon countries and was initially used in 1977 by the United Kingdom (U.K). Since then, its popularity has increased worldwide. Earlier studies by researchers and many other professional sectors and departments have introduced PPP contracts into different execution modes like Build, Operate, and Transfer (BOT); Build, Own, Operate, and Transfer (BOOT); and Build, Lease, and Transfer (BLT), etc. All definitions of PPP contracts are different but have a few common characteristics and risks. Previously, numerous pieces of literature were available on these common risks for various execution modes of PPP contracts. However, each PPP mode still has unique risks that must be identified to understand and successfully implement the PPP projects properly. This paper fills the gap mentioned above and aims to identify various commonly used PPP execution modes in infrastructure projects and their corresponding risks after placing the different PPP execution modes into four (04) different categories. Identified risks for the corresponding PPP categories were also divided into seven (07) stages of the PPP life cycle. Semi-structured interviews were conducted to gather information from thirty-four (34) PPP experts worldwide. Accordingly, interviews are transcribed and processed for thematic analysis in academic NVIVO software. These identified risks are further placed in the respective PPP category for the convenience and better understanding of the study’s outcome to the users and for the subsequent prioritization and allocation of these identified risks accordingly to the PPP parties during the finalization of the PPP execution mode.

Use of total quality management to enhance the quality of design and build projects

Governments of many developing countries that are unable to develop their infrastructure in order to obtain financial resources prefer to establish public–private partnerships (PPPs) for providing the much-required infrastructure. Time is thus opportune for Sri Lanka, which is also a developing country, to make use of PPPs to develop its road network. The purpose of this paper is, therefore, to identify the PPP models that suit road construction in Sri Lanka.,The study used a mixed approach. The characteristics of road construction, procurement selection factors to be considered in road construction, and the different PPP models that can be used for such procurements were identified through a comprehensive literature synthesis. The findings were validated using expert interviews. A questionnaire survey identified the PPP models that suit road construction in Sri Lanka. The most suitable model among them was identified by ranking the PPP models using procurement selection factors.,Build–Own–Operate–Transfer was identified as the PPP model that best suits road construction in Sri Lanka. However, investors may not find it attractive because of its high payback period, a result of the low traffic volume in Sri Lanka. Therefore, a PPP model that involves road construction alone will not be feasible in Sri Lanka. It will have to include the construction of other infrastructure as well.,The study identifies a PPP model that best suits the road construction projects in Sri Lanka.
