    Utility factors affecting for selecting delay analysis technique

    Delays in the completion of scheduled activities as per the work plan will invariably lead to delays in construction. Such delays play havoc in the construction industry especially in a sustainable environment leading to many issues and disputes which in many cases retard the progress of the project. Therefore, minimizing delays is one of the most important factors in sustainable construction. Due to its criticality, a wide range of Delay Analysis Techniques (DAT) has been developed by various analysts over the years to address the issue. Further, with the emergence of new scenarios in sustainable construction with the passage of time, analysts have identified the inherent properties of each of these methodologies. These inherent properties or factors in turn become indicators for measuring the suitability and accuracy of DAT in a given context where they can be grouped into filter and utility factors. However, in the Sri Lankan construction industry, the resolving and managing of construction delays remain at an elementary stage with most analysts opting for an ad-hoc selection rather than being governed by considerations of suitability. This paper contains the findings of a literature review and interviews with experts which compare DAT and factors affecting the selection of DAT. The methodology adopted in undertaking this research is a case study and document reviews. The findings of the study will direct analysts to select the most suitable DAT and to reduce the error margin in delay analysis while aiding the increase in accuracy of delay analysis.

    Viability of private sector involvement in infrastructure project development in developing countryiability of private sector involvement in infrastructure project development in developing country
    (Ceylon Institute of Builders - Sri Lanka, 2013-06) Tanabe, SM; Ranasinghe, M; Sandayake, YG; Fernando, NG
    Since public infrastructures underpin economic and social development, infrastructure project development is essential for the sustainable growth of a country. In many developing countries, large scale infrastructure projects are undertaken through conventional public procurement, using bilateral and/or multilateral funding. On the other hand, the financial capacity and practical project management know-how of the private sector is an attractive option for the government for the sustainable construction of new infrastructures from the macro aspect. For example an infrastructure development financed by the private sector is off-balance sheet, enabling the government to invest more public funds for social projects. The more popular index used for evaluating the economic feasibility is the Economic Internal Rate of Return (EIRR). The calculation of the EIRR does not capture the feasibility or viability of a project when the private sector is involved in its development because the realistic financial and other risks are not sufficiently assessed and incorporated into the analysis. This paper aims to present a framework to assess the viability of public infrastructure projects reflecting the various risks involved in a project by quantifying and incorporating them to the cash flows and the financial analysis.
