Disputes in construction projects affect not only delay in construction progress but also its cost and potentially its quality. Disputes in construction projects affect not only delay in construction progress but also its cost and potentially its quality. The construction industry of Sri Lanka contributes significantly to its economy and the cost of construction disputes can influence its economic welfare. It is important to understand the significant disputes in the Sri Lankan construction industry in order to mitigate this cost. A qualitative descriptive study has been conducted through semi-structured questionnaires analyzed using a thematic approach. The sample comprised of 10-construction industry professionals all involved in the dispute resolution process. The literature identified 7 main dispute causes as being owner related, contractor related, project related, design related, contract related, human behavior related and consultant related. The interviews identified sub themes from each, which were then ranked in order to identify those that were most significant. It was found that many of the sub themes were interrelated and that one cause could be the creation of another. The lack of appropriate communication between parties and lack of team spirit were identified as the genesis of disputes in the Sri Lankan construction industry.

During COVID’19 crisis, small and medium-scale businesses suffer the most and are the least prepared among all companies as per the previous studies done in other parts of the world. The majority of the small-scale construction firms in Sri Lanka act as subcontractors and generate job opportunities for a considerable number of people and are able to create a multiplier effect on the whole economy. However, it was observed that they are more vulnerable to the adverse impact of the pandemic. Thus, the principal goal of this research is to explore possible survival strategies to overcome critical financial issues of small-scale construction companies during the ongoing COVID-19 pandemic in Sri Lanka. A mixed method approach was adopted to gather the data for the study. The data for this study was gathered using semi-structured interviews and a comprehensive questionnaire survey with small scale construction company owners and construction industry professionals. The findings highlighted the key financial issues faced by the small-scale construction companies due to the pandemic including delays in client payments, supply chain management issues, frequent price escalation of construction materials, and inability to repay loans. The respondents suggested creating partnerships with financially strong companies, reduction of unwanted expenses, modifying supply chain channels and agreements, and ensuring business continuity plans as the strategies to be used to overcome the financial burden that occurred due to the pandemic.

Due to numerous financial difficulties governments move towards Collaborative procurement methods to secure infrastructure projects with participation of private sector. Sri Lanka is still lagging in implementing proper collaborative partnerships in infrastructure developments. Sri Lankan energy sector highly depends on hydro and expensive diesel power plants. Because of that, in dry season Sri Lanka is facing huge generation gap in meeting demand. To overcome these challenges Sri Lanka urgently needs to implement new power plants with more economical power sources. Therefore, the aim of the study is set to identify suitable collaborative procurement methods and develop the framework for processing those new projects. Barriers to implement collaborative energy sector projects were identified through literature review and expert interviews. Explored barriers were categorized into Social, Economic, Political and Regulatory discipline and key measures were proposed to overcome such. The suitable procurement routes for each energy project were brought to the new knowledge considering power generation capacity of power plants and prevailing regulations. Finally, the framework was developed to adopt proper implementation of identified procurement methods in Sri Lankan energy sector.

COVID-19 pandemic has resulted in almost every construction project getting delayed or disrupted. This research aims to determine the factors that caused delays and disruptions in large scale construction projects in Sri Lanka due to pandemic. The overall impact of the global pandemic on construction projects in both local and international platforms were identified through a comprehensive literature review. Additionally, the impact on the local domain in terms of delay and disruption was assessed based on exploratory interviews and survey questionnaire disseminated among industry experts. The findings also paved the way to recognize innovative mitigation strategies to control the adverse impact on on-going construction projects. Analysis of the responses concluded that, delay in project kick-off, delays in material delivery, shortage of material, project suspension, reduction in the workforce productivity, health and safety concerns, regular price escalations as the key elements attributed to impact the project progress. The study has identified the present mitigating controls over delays or disruption are barely sufficient to address the concern and thus emphasised the need to resort to more effective techniques to remedy the issue.

3D construction could boost construction efficiency and effectiveness, but it has been still a failure to incorporate this technology into Sri Lanka's construction industry. This research is aimed to identify the ways of incorporating 3D printing technology in the construction industry. Experts were surveyed regularly to identify obstacles and facilitators of 3D construction.  "Unprepared workforce," "lack of norms or rules for 3D printing technology," and "expensive investment requirements" were the top three impediments. Top enablers were design flexibility, cost reductions, and time savings. In conclusion, three strategies were identified as the best potential enables on adoption of 3D printing in Sri Lanka: "Conduct training for industry personnel on how to engage with 3D printing," "enable the collaborative approach (partnering)," and "Construction industry to build a new set of standards, norms, rules and laws relevant to adaption of 3D printing into construction industry."
