Estimasi Biaya Konstruksi Menggunakan Metode Parameter Pada Proyek Pemeliharaan Berkala Jalan Di Kota Manado

Abstract

Cost estimation plays an important role in the implementation of construction projects. Activity
estimation is one of the main processes in a construction project to know the amount of funds that must
be provided for a building. In general, a construction project costs a lot. The inaccuracies that occur in
the supply will be less good to the parties involved. However, the owner of the project requires cost
estimation in order to prepare the project budget. In estimating the initial cost of the periodic
maintenance project the road still uses a simple way. The most commonly used method is to estimate
the road length parameters, ie by calculating the periodic maintenance cost of the road for every 1 km
of road length based on the previous project data. So that with the budget available the owner of the
project (owner) can provide long information path that will get regular maintenance activities.
      The length of a road segment shows the physical characteristics and size of a periodic road
maintenance project that in practicality this information can be readily available in the early stages of
project planning. Along with the need for efficiency, it is necessary to develop techniques for making a
simple cost estimation model. What is important in the cost estimation model in the early stages of
project planning is to be quick, easy to use, accurate and generate reliable estimates.
      The aims of this research are to produce the project cost estimation model of periodic road
maintenance for the relationship between Total Project Cost and LPA volume and ACWC volume,
To produce a project cost estimation model of periodic road maintenance for the relationship between
the Total Project Cost and the ACWC volume and to produce the project cost estimation model of
periodic road maintenance for the relationship between Total Project Cost and LPA volume.
      The method used are parameter method. Based on the results of the analysis that has been done, it
can be concluded in order to estimate the cost of the periodic maintenance project of roads in Manada
city, in accordance with the research objectives as follows: The project cost estimation model for the
relationship between Total Project Cost of Routine Road Maintenance with LPA volume and ACWC
volume is as follows: Total Cost = 2373898,22 LPA + 115476,64 ACWC + 283033186,7 with
correlation value equal to 94,70% and determination value equal to 89,70%. The project cost estimation
model for the relationship between the Total Cost of the Road Maintenance Project Period with ACWC
volume ie: Total Cost = 186688,461 ACWC + 699100355,10 with r = 89,90% and r2 = 80,80%. The
project cost estimation model for the relationship between Total Project Cost of Routine Road
Maintenance with LPA volume ie: Total Cost = 4567920,593 LPA + 30710896,10 with correlation
value of 87.40% and determination value of 76.40%.
