Abstract:
In broad classification of construction projects, building construction project is the one. In
building construction project there are many activities should be done to change the drawing
into tangible object. During execution of the construction problems are encountered as a
consequence of engaged parties problems and/or natural problems. Due to those problems
most of the time the best project performance is not achievable. The objective of this study was
evaluation of building construction performance in terms of cost performance, time
performance and forecast the future project cost by using earned value analysis next to that
find out the major responsible causes for variations and to make recommendations for
construction parties engaged in building construction projects to improve performance based
on the outcome of the study. As a case study, six building construction projects were selected
using non-probability purposive sampling, four of them are ongoing, during data collection,
and two of them are finished. Data from six construction projects was analyzed using MS Excel
and statistical RII formula. Based on the selected building construction projects, all projects
showed poor in cost and schedule performances. In result dormitory II and classroom project
noted the maximum and minimum schedule variance which was -78 and -35 percent behind
schedule time. Similarly canteen and dormitory II projects showed minimum and maximum
cost variance by scoring -1 percent and -29.93 percent over budgeted from original budget.
The maximum Cost and Schedule performance index values were recorded on canteen and
class room projects with values of 0.99 and 0.67. The lowest Cost and Schedule performance
index values were recorded on both dormitory II project with values of 0.77 and 0.06. From
all six projects, dormitory II project forecasted completion cost showed the highest difference
with budgeted at completion. By using RII ranking design change, actual quantity of activity
greater than planned and Shortage of skilled and unskilled labor has been top three major
responsible causes by scoring RII of 0.912, 0.907 and 0.864 respectively. It is recommended
that the owner should be set the scope, cost and time of the project according to actual. Design
and material changes should be considered during planning. The contractor should also
deliver construction materials and equipment as per schedule. Again the consultants should
delivered the drawing as per schedule.
