Ethiopian construction industry participants have long recognized that accepting the lowest
price bid does not guarantee maximum value.For the success of any construction project
time, cost, quality, and safety performance are the fundamental criteria. More than 50% of
theEthio-telecom construction projects are awarded using lowest bidder bid awarding system
and most of the contractor of the projects fails to complete and handover the project to the
client asper the agreement. Consequently, most of the project face huge amount of time and
cost overrun. The other Ethio-telecom construction projects are awarded by fixed price
invitation methods almost 98% of the construction project completed with the give time and
price, which was awarded by fixed price system. This study focuses the first stated awarding
system and tried to analyze the performance of least bidder contractors under Ethio-telecom
projects. In this study other factors responsible for impacting the time, cost, safety, and
quality performance of Ethio-telecom construction projects were also analyzed. The research
has adopted descriptive type of research design and the probability sampling was used to
identify the target population; and the target populations were the number of construction
projects which was completed in the last five years. The sources of data for this research
were primary and secondary data. The primary data were gathered formally through a
questionnaires and direct interview of stakeholders which are working in the construction
projects. And, the secondary data was gathered through reviewing, examination of
documents, reports and records of published documents. Relative importance Index was used
to analyze the data. The findings of study revealed that, in average 48.80% of construction
projects were time overrun and only 51.20 % of project could achieve completion within
contract duration. The amount of time overrun varies between 21.85-80.00%. Cost overrun
was in between 0-25% as agreed by respondents with an average of around 10%.The major
contributors of this poor performance related to cost are identified and ranked based on their
relative importance index (RII) accordingly, Unfair estimation of project contract period
(RII=0.808), Lack of proper supervisions (RII=0.806), and Poor scheduling during
construction (RII=0.794) were top three factors. Similarly, factors related to time
performance were identified and ranked, accordingly, Selection of lower grade of contractor
(RII=0.930), Poor human resource management (RII=0.850), and Lack of proper work
planning, and scheduling (RII=0.812) were top three factors. Generally, from this study it
can be concluded that, the contractor’s performance under lowest bidder bid awarding
system was poor in both cost and time context. Hence, Ethio-telecom as client recommended
is changing bid warding system to effectively perform the projects progress since it is crucial
for development of our country. |
