| Abstract | In a developing country like Nepal, where in most cases the
projects are externally financed, there is still the overiding
tendency to overemphasise the minimisation of construction costs
in a highway project. But the cost estimates to be used at the
earlier stage of design, where only a limited data will be
available for analysis, have usually been based on lump sum unit
costs derived from historic data on similar schemes, which often
may not give a satisfactory result.
A generalised model is hence analysed which could be used
for any part of the country in any topographical conditions to
estimate the construction cost for a highway project at the route
location stage with the constraints of Nepal Road Standards and
current practice. The model basically consists of three parts for
the estimation of earthwork cost, retaining wall cost and the
bridge cost respectively. Each part of the model is independent
to each other and hence can also be used independently.
The basic input data required is the general topographical
information of the area concerned in terms of topographical
contoured maps. The model assumes a predetermined horizontal
alignment and the centre line profile of the ground surf ace has
to be prepared at around 1:10000 horizontal and 1:2000 vertical
scale.
The results obtained were satisfactory and hence can be used
to estimate the parameters successfully. The estimate tested was
well within the accuracy desired at the earlier stage of design
and the statistical test on the accuracy of the mode l shows a
satisfactory result. |
