Abstract
Housing projects have an impact on personal, socio-economic as well as political conditions. As a result,
it is essential to assess the actual causes of delay and constraint in order to minimize the delays and their
corresponding costs and time. Successful completion of projects leads to socio economic growth and helps
to provide good social welfare. The objective of this thesis is to investigate the main causes of delays and
constraints as well as effects of delays in AAHDPO project. The study were used both Primary and
secondary data sources to collect the necessary information. Two type of sampling techniques were
used namely random and purposive sampling. Two Projects specifically Koye feche (10/90) and Kileto
(20/80) were selected randomly based on the lists from HDPO office. The respondents were contractors,
consultants and clients who worked in the Koye-feche and Kileto projects. The structured questionnaire
in Likert scale was distributed and collected at a selected site of the case study. There are many causes
that induce delay in HDPO construction projects. Before identifying the causes of delays the study was to
test whether delay in HDPO had been found/ existing or not. From the above sample survey results
understand that more than 78.18 percent of the respondents agreed the HDPO construction is exposed to
delay. Moreover, Interviews conducted with some of the officials in HDPO indicated that delay is the
main challenge for construction projects. The relative important index (RII) was computed for each cause
to identify the most significant causes and later the causes of delays were ranked based on the RII; results
showed that the ten critical factors that contribute to project delays in HDPO are; delays in the payment
for services, Shortages in basic materials, Slow decision making by all functional group, inaccurate cost
and time estimate, poor infrastructure development, poor capacity of contractor and sub-contractor, Poor
risk management and inadequate financial availability as planned through project duration. The critical
effects of delays are time overrun, cost overrun, litigation/ legal action, Public dissatisfaction or loss of
belief of citizen, termination and disputes. After the causes and effects could be observed and provide a
clue to minimizing delay on construction sites. This study has also delivered recommendation, all of that
will assist client organizations to curb the problems associated with delays and constraints in its project
implementation.
