Sažetak
Procurement method over time has proven to have
significant influence on the successful delivery of construction
projects. Making the right decision in the selection of a
procurement option to adopt is therefore crucial if a project
is to succeed. This study therefore assessed the cost and time
performance of selected public building projects procured
using traditional, direct labour and management procurement
options in Ondo State, Nigeria. A pro forma was used to
gather cost and time data from government procuring entities
in the state. In addition, a structured questionnaire was
used to obtain information from construction professionals
in these procuring entities, in order to ascertain the factors
influencing the choice of procurement options adopted. The
cost and time data gathered were analyzed using percentages
and the paired-samples t-test, while those gathered on
the factors influencing the choice of procurement options
were analyzed using mean item scores and analysis of variance
(ANOVA). The results revealed that although there is
no significant difference between the initial and final costs
of the assessed projects, some measure of cost overrun still
exists. In addition, a considerable amount of time overrun
was experienced on projects executed using the three different
procurement options. The most significant factors influencing
the choice of a procurement option are price competition,
speed, time certainty and complexity of the project. It
is believed that the findings of this study will provide public
procuring entities with insight on the cost and time capability
of these procurement methods and aid them in selecting the procurement option that will help in delivering public
building projects within the budget and on schedule.
