Abstract:
The construction industry plays a major role in the economy as its share of the Gross Domestic
Product (GDP) and its interaction with other sectors of the economy. Construction projects are
always expected to create a balance between cost, time and quality. Achieving success in
building implementation process is the major function of project management. Building
construction is the process of adding structure to real property or construction of buildings.
Although building construction projects consist of common elements such as design, financial,
estimating and legal considerations, projects of varying sizes may reach undesirable end results,
such as structural collapse, cost overruns, and/or litigation. For this reason, those with
experience in the field make detailed plans and maintain careful oversight during the project to
ensure a positive outcome. Quality of projects is one of the traditional and global measure of
project performance. For construction projects, the goal and desire of clients, contractors and
consultants is to ensure that projects are delivered according to acceptable and agreed
standards. Cost estimating is an assessment of the expected cost of any construction project. The
accuracy of such estimate has a serious effect on the expected profit of the construction
contractor. Schedule delay can be defined as a discrepancy where actual completion of the
project exceeds the planed period according to the contract. For this study the researcher tries
to select the appropriate data analysis method which is regression analysis. The mean and the
standard deviation as well as the spearman rank correlation coefficient of different variable
were calculated using SPSS version 20.00. Out of the data collected through questioner and
interview. Generally, building construction projects, in Jimma Zone, were determined with
quality, cost and time factors. According to the information particularly obtained through
interview, company’s financial strength, lack of effective communication between stakeholders,
effective scheduling and effective site management plus client consultation and support were
critical success factors in building construction projects. My recommendation in order to change
this problem… Offering license of building only for highly trained personnel's and professionals.
The triangulation among consultants, contractors and clients should be strengthened by legal
framework
