Abstract
Construction industry is a very important industry for the economic development of the
country. However, this industry has been facing serious problems i.e. failure to complete
projects within stipulated time and cost and abandoning of projects which always drain public
funds to waste. This is one of the critical issues faced by the metropolitan, the municipal and
the district assemblies in Ghana. Hence, the reason for evaluating the risk factors that cause
schedule and cost overruns in the delivery of public sector construction works within these
MMDA‟S in Ghana and to recommend measures that must be put in place to mitigate or
reduce this problem. A total of 34 factors were identified from previous studies. The data
collections were carried out using structured questionnaire survey. Nominal group technique
was used to attach probabilities to determine the level of occurrence and severity of impact
using the risk matrix. The evaluated risks were categorised into high, medium and low risks.
This study found that there were 18 high risk factors and 7 medium and low risk factors. The
key recommendation advanced by the research due to the agreeability of the reviewed
mitigation variables are; The MMDA‟s must ensure prompt payment of any work done by
the contractors; planned projects to be executed must be sizeable enough to meet the
available budget allocation; The MMDA‟s must ensure that before any tendering
advertisement is done, all design details are completed to enable accurate extraction of
quantities and proper view of the design proposal; monitoring and evaluation of the work is
important, this will enable the contractors to stay within the scope of the work and finally,
contractors must not be awarded contracts based on political grounds, but their capabilities to
perform the contract must be ascertained.
