Israel, B (2023) The impact of clients' procurement challenges on the substance goals of roads construction projects in songwe, Tanzania. International Journal of Construction Management, 23(12), pp. 2144-2150. ISSN 1562-3599
Abstract
Execution of construction projects within the estimated timeline, budget and quality are the prime substance goals of procurement projects. Delays result into cost-overrun and attempts to minimise cost result into delays or delivery of sub-standard projects. This study examines the impact of clients' procurement challenges that hinder realisation of project’s cost effective, quality standards and timely delivery using descriptive research design. Data were collected from 83 contractors and consultants with reference to their involvement in Songwe’s roads construction projects. Data were analysed using descriptive statistics and Multinomial Logistic Regression. The findings are that 35.44% of projects revealed cost-overrun, 56.96% had time-overrun, and 6.56% never meet quality standards. Corruption, financial constraints, unrealistic contract durations, non-compliance with contractual terms and conditions are the typical clients' procurement challenges that hamper the substance goals of roads construction projects, resulting into financial penalties, project abandonment and contractual disputes. The article highlights and documents the clients' procurement challenges in Tanzania’s roads construction projects that have not been adequately researched. To policy makers, project practitioners, scholars and oversight authorities, the article informs on the indicators that impede cost, quality and timely delivery of construction projects. Non-procurement and contractors' challenges impeding project’s cost, time and quality were not taken into account.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
