Abstract
Construction delays are common problems in water supply projects in Ethiopia. The delays in
construction projects are the major causes of project failure. If the delay is not identified and the
corrective project management decision is not taken in time a project may incur extra cost and
extension of project time, which gives rise to dissatisfaction to all the parties involved and
nowadays it’s becoming a major obstruction for their development for developing countries like
Ethiopia. The research intended to identify the major causes that are led to project delay. To
achieve the objective, the study employed descriptive research approach and both primary and
secondary data were used. Questionnaires and desk review was tools used collect the data
required. This research first identified 58 factors causing delay in Ethiopian water supply
construction sector, and then the most common and critical causes of construction delay were
evaluated by the data collected in a survey of program managers, regional coordinators and site
engineers. The findings show that the main critical factors that cause construction delays in water
supply sector in Ethiopia are: (1) adverse weather condition, (2) delay in approval of documents,
(3) equipment Failure, (4) scarcity of material in the market,(5) poor supervision, (6) poor site
management, (7) fluctuation of prices of materials, (8) change in subsurface conditions, (9)
slowness in decision making process and, (10) low skills of labor.
