(Department of Building Economics, 2024) Sood, R; Sharma, N; Laishram, B; Sandanayake, YG; Waidyasekara, KGAS; Ranadewa, KATO; Chandanie, H
The Architectural, Engineering, Construction, and Operations (AECO) industry has implemented Building Information Modelling (BIM) for a significant time, and its applications are widely recognised. Nevertheless, numerous studies have emphasised that BIM in isolation is unable to tackle the difficulties encountered by construction stakeholders and needs integration with other technologies to augment its practicality. In the last few years, there has been an increasing curiosity and utilisation of Blockchain Technology (BCT) within the construction industry. Limited research has been conducted on the amalgamation of BIM and BCT across many domains of application. To undertake a thorough analysis of the integration between BIM and BCT, this study employed a Systematic Literature Review (SLR) methodology utilising the Scopus database. The research employed a combination of quantitative and qualitative content analysis techniques to examine the selected articles. The study has identified five distinct domains of integration between BIM and BCT. These domains encompass data management, contract management, facility/asset management, sustainability/waste management, and supply chain management. Furthermore, certain obstacles were identified that impact the incorporation of BIM-BCT in the industry. In general, this study can provide stakeholders with insights into the capabilities of BIM-BCT within the construction industry, enabling them to develop a strategic plan for improving the integration of these technologies

Building information modeling in Public Private Partnership Projects – perspectives and hurdles
(2013-12-01) Laishram, B
Building Information Modeling (BIM) has received widespread attention in the management of built environment with the potential to change the traditional construction practices. BIM promotes an integrated project delivery approach that encourages collaboration amongst the various stakeholders to the project over its lifecycle. The perceived benefits from collaboration such as improved profitability, reduced costs, better time management and improved customer/contractor relationships have been amongst the factors driving the paradigm shift towards BIM. However, there are various barriers affecting the implementation of BIM in construction projects. Legal pitfalls, besides the technological issues, have been amongst the barriers to efficient implementation of BIM. The legal risks assume a bigger hurdle in BIM adoption for construction projects procured through public private partnership (PPP) route such as build-operate-transfer (BOT) on account of the highly complex contractual relationships amongst the various stakeholders to the project. PPP projects have additional confidentiality, commercial, financial, and legal complexities besides the technical and managerial issues of traditional design-build projects. The paper discusses the hurdles in the implementation of BIM to manage the construction projects procured through PPP route, which has become one of the preferred routes for procurement of projects in developed and developing countries in view of the budgetary constraints faced by the governments. The paper concludes with additional legal and contractual measures that should be included in contractual package of PPP projects in order to facilitate BIM for management of the projects.

Mapping global trends in cost of quality dynamics: a bibliometric study
(Department of Building Economics, 2024) Sharma, N; Sood, R; Laishram, B; Sandanayake, YG; Waidyasekara, KGAS; Ranadewa, KATO; Chandanie, H
In the construction industry, unique projects and complex dynamics pose challenges for maintaining high-quality standards. An inadequate Quality Management System (QMS) can lead to extra costs and delays, highlighting the importance of methodologies such as the Cost of Quality (COQ). Despite extensive knowledge in manufacturing, the construction sector lags in adopting COQ. A systematic review is needed to understand COQ developments in construction, informing better practices and cost reduction strategies. A Systematic Literature Review (SLR) and bibliometric analysis were carried out utilising 27 peer-reviewed papers obtained from the Scopus database. The present study utilises a range of tools, including VOSviewer and Litmaps to facilitate descriptive analysis, bibliometric analysis, and network visualisation. The purpose of this study is to investigate different aspects of the COQ and analyse different patterns and models related to it in the context of the construction industry. The present study systematically presents potential avenues for future research that have been identified in the existing literature.

A review of drivers of sustainability in mega infrastructure projects: An institutional approach.
(2022-06-24) Thounaojam, N; Devkar, Devkar, G; Laishram, B; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
The need for sustainable practices in megaproject implementation is becoming acute. With the ongoing progress and expansion of mega infrastructure projects (MIPs), a lot of attention has been attracted among policymakers and researchers due to their enormous impacts on the economy, society, and the environment. Given the complexity of MIPs and the sustainability-related challenges it faces; the successful management of sustainability-related targets requires influence from the institutional forces (regulative, normative and cultural-cognitive). However, existing research on the institutional drivers that can effectively promote the sustainability of megaprojects has been largely unexplored and calls for attention. Therefore, this study aims to present a review of what drives the adoption of sustainable practices in MIPs. A systematic literature review was conducted based on a combination of keyword search in the Scopus database. Using the lens of institutional theory and deductive approach, 11 drivers for sustainability in MIPs were identified from reviewing 33 selected peer-reviewed articles. This study would enhance project stakeholders’ and policymakers’ understanding of drivers for sustainability and help further improve policies, strategies, norms and culture to support MIPs in contributing to sustainable development goals.

A review on unexploited features of n-dimensional BIM: An Indian construction scenario.
(2022-06-24) Sood, R; Laishram, B; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
Infrastructure sector is a backbone of economic development for most of the countries worldwide. Indian AEC (Architecture, Engineering and Construction) industry is one of the leading sectors in terms of Gross Domestic Product (GDP) and employment. With the increasing demand for infrastructure and continuous development in field of technology, the speed of construction has been improved in various countries. But most of the projects still face the issues of cost and time overruns due to un-exploitation of digital tools and technology. Building Information Modeling (BIM) is one such promising technology that spans several levels of maturity (Level 0, 1, 2, and 3) and dimensions (3D, 4D, 5D, 6D and 7D). Many studies have shown that the construction industry is still lagging behind the rate with which technology should have been adapted, particularly in developing countries including India. This paper, therefore aims to answer systematically about various dimensions and level of maturity and its current status in Indian construction industry and the key factors responsible for un-exploitation of BIM’s features due to low maturity. Finally, the paper presented some future research agendas. The study’s findings may be of significant value to the practitioners and policymakers in incorporating mandatory BIM based framework for Indian construction industry and also in other developing nations.

Strategies to enhance sustainability of public private partnership procurement process for infrastructure development
(Ceylon Institute of Builders, 2015-06) Patil, NA; Laishram, B; Sandanayake, YG; Fernando, NG; Karunasena, GI
Public Private Partnerships (PPPs) have been used as one of the preferred modes for infrastructure development since the last two decades in India. The PPP programme in India, though, has stabilized significantly with lessons learnt from the experience of implementing PPP projects, but the PPPs in India still suffers from certain shortfalls which could be related to the failure to meet many aspects of sustainable development (SD) principles. One of the ways to overcome these shortfalls could to modify the procurement process so as to fulfil the principles of SD even through PPP route. The main aim of this paper is to develop a conceptual framework highlighting the strategies for integrating sustainability principles in procurement process of PPP projects. Content analysis on existing literatures, research reports, and case studies on PPP projects has been adopted to first identify the shortfalls in PPP process and, secondly, examine the possible strategies from best practices being adopted in PPP projects executed all over the world. The preliminary framework on how to integrate the principles of sustainability is then conceptualized explaining how the formulated strategies can be integrated into PPP process. Finally, focused interviews with the key stakeholders of PPP projects have been undertaken to assess the feasibility of the preliminary framework. The preliminary findings from the study indicate the opportunities to promote SD even through PPP route if procurement process is enhanced with respect to the following aspects by relooking the PPP process from the perspective of SD concepts and principles: stakeholder’s participation, environment impact assessment, value for money analysis, user’s charges and risk allocation policies, transaction and bidding cost, and bid evaluation criteria. The proposed framework will be a useful tool for the government to restructure the PPP procurement process in India to fulfil the SD goals, which are being currently pursued by the government rigorously.

Sustainability practices implemented in the Indian construction industry: a focus of construction phase
(Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Thounaojam, N; Devkar, G; Laishram, B
The construction industry is crucial to the global economy, significantly contributing to local economies and their overall productivity. This is evident in India also, where the construction sector has substantially driven economic growth and development. However, as this industry grows, it poses a significant risk to environmental degradation. While sustainability in construction industry is often investigated from the perspective of design and planning phases, there is also growing recognition of the importance of addressing sustainability during construction phase. A quantitative approach was utilised to investigate the degree to which sustainable practices during construction phase (SPCPs) are implemented in India. Data was gathered from clients, contractors, and consultants, and 40 responses were obtained from 147 respondents contacted. The level of implementation of SPCPs was ranked, and analysis of variance (ANOVA) was conducted to test the significant difference in perceptions among the three groups of respondents. The results indicated that five most frequently implemented SPCPs are: (i) health and safety inspection and auditing; (ii) health and safety training and education; (iii) preservation of archaeological sites, vegetation, and trees; (iv) construction equipment/machinery handling and utilisation strategy and (v) quality management systems. Some of the other fundamental sustainable practices that are under-implemented are: (i) construction noise/ vibration reduction measures; (ii) preassembly or off-site fabrication; (iii) sustainability assessment and recognition program and (iv) stormwater and greywater management plan. Findings of this study can provide guidance to construction industry practitioners in identifying areas that require enhancements, thereby fostering a collaborative approach towards advancing sustainable development goals
