Abstract


Time, money, and quality are the three basic criteria for measuring construction project efficiency. The Ethiopian construction sector in general and public work projects, in particular, are believed to suffer from inefficiencies despite their quantitative growth in recent years. Previous researches have made attempts to explore factors determining the efficiency of the sector such as the low capacity of contractors (both financial and equipment, shortage of skilled human resource on technical, managerial, and entrepreneurial skills, etc…), the poor performances of the supply chain, inflation in the economy and so on. However, process and system-based challenges of the sector resulting from the existing legal frameworks governing the sector such as the modes of delivery of projects (modes of contracting) have not been a subject of extensive study. In this study, doctrinal and non-doctrinal legal research methods are employed to explore project delivery system(s) recognized in Ethiopia's public work contract laws and appraise their efficiency in terms of ensuring prompt completion of public construction projects. The doctrinal aspect of the research exposed that, despite an implied recognition of Design-Build (DB) and its variant forms of project delivery system, the country's public work contract laws set up Design-Bid-Build (DBB) as a default mode of contracting. Besides, the result from a survey questionnaire of 158 respondents which was computed by using Research Package for Social Sciences (SPSS) to generate the Relative Importance Index (RII) of each mode of contracting corroborated by primary data derived from the completion and status report of 40 road and 9 building projects, shows that even though construction project time overrun (delay) often happens in both routes of contracting, the magnitude of such inefficiency is greater in public projects of DBB than DB delivery mode.


 


1. Introduction


The construction industry is one among numerous sectors of an economy that make significant contributions to the socio-economic development of a country. It directly affects the economy of a country by providing huge employment opportunities to unskilled, semi-skilled, and skilled sections of the community of a country and indirectly through exploiting goods and services produced by other subsectors (Berk and Bicen 2017). The construction industry also fuels the economy of a country as a result of its strong multiplier effect through a complex system of linkages with other sectors, and therefore, the growth of all the economic sub-sectors such as modern agriculture, manufacturing, and the like is inconceivable without the construction industry. To regulate this important but complex and multifaceted sector of an economy and determine the rights and liabilities of stakeholders in construction projects, countries put in place different laws and regulatory institutions. Efficient completion of a construction project among other things highly requires a synergetic operation of its stakeholders who take different but complementary tasks such as planning, design, procurement, financing, and construction, and so on.
