Allocation of risks to parties involved in Sri Lankan road construction projects : a Delphi study.
(2015-04-11) Perera, BAKS; Rameezdeen, R; Chileshe, N; Hosseini, M
The findings of a broad literature review as the first stage of this study indicated that identifying risk factors on a lifecycle basis and defining the shares of the parties involved in projects in terms of dealing with risks would increase the effectiveness of risk management studies. Drawing upon the foregoing results, this study aimed at ascertaining the main risks and accordingly allocating them to the parties involved in each phase of the road construction projects in Sri Lanka deploying a three-round Delphi study. The outcomes of the Delphi revealed that the construction and the design phase are the most critical phases of a road project due to the prevalence of major risks in these phases. Besides, some critical risk factors occurring in more than one phase of the project life cycle were identified which necessitated the primacy of handling these risk factors as a prerequisite for success of road projects in Sri Lanka. The study concludes with presenting the potential sources of the identified risk factors and the stake of each party to handle the risks. The paper would contribute to the risk management literature in other countries explicitly developing countries facing the analogous challenges.

Enhancing the effectiveness of risk management practices in Sri Lankan road construction projects : a delphi approach
Perera, BAKS; Rameezdeen, R; Chileshe, N; Hosseini, MR
The purpose of this study was twofold: (1) Identifying the risks that are critical for risk management of road construction projects in Sri Lanka on a life cycle basis and (2) defining the shares of the parties involved in projects in terms of handling the identified risks. A Delphi study was conducted among 33 Sri Lankan experts (consultants, project managers, contractors) in three rounds. The findings showed that the construction and design phases are prone to many major risks.

From grave-to-cradle: quality assurance system for the demolition waste management
(Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Wijewickrama, MKCS; Chileshe, N; Rameezdeen, R; Ochoa, JJ
The recent decade has witnessed significant demolition waste (DW) due to rapid urbanisation in many economies. Transforming from the traditional linear supply chains into a circular arrangement while thinking from ‘grave-to-cradle’ is a value-adding approach to managing DW effectively. Consequently, the concept of ‘reverse logistics supply chains (RLSC)’ has captured the attention of the construction industry. However, the poor quality of re-processed products has hindered the successful adoption of RLSC in the construction industry. Therefore, this study examines aspects of the quality assurance system needed for RLSC to manage DW effectively and efficiently. The study used a qualitative approach, including 20 semi-structured interviews with internal stakeholders of the RLSC of DW. The study empirically confirmed that the RLSC of DW should embrace an integrated system for QA, including four aspects: process, people, policy, and technology. Under process for QA, standard practices are to be undertaken separately during building dismantling and off-site waste processing stages. While people in RLSC are skilful, competent, licensed, supervised and monitored, internal and external organisational policies should also be available for QA. Besides, espousing traditional practices with innovative technologies is also imperative for QA in RLSC of DW. The study makes a significant contribution by empirically proving that an integrated system of process, people, policy and technology is needed for QA in RLSC of DW. The developed quality assurance system provides useful insights for industry practitioners about the aspects that they should embrace in enforcing QA throughout the transformation from ‘grave-to-cradle’ in the construction industry.
