Abstract :
Over the years, there have been ineffective
and inaccurate results being noticed to have been gotten
over time when bill of civil and engineering quantities are
computed manually. However, with the aid of a
developed software package in calculating the bill of
quantities, effective and efficient results would be gotten.
From the foregoing this study aims at developing a
computer aided model to digitally compute building and
civil engineering quantities using C# programming
language. The approach used in this study is developing
the digital computation program and testing the
computational program using the manual taking off
from both residential building and road plans to validate
the software. The results obtained from this study
indicate that, with reference to the residential building
plan, 100% of the substructure items found in the bill fall
within 0 to 0.05 percentage difference and 75% of the
superstructure items have 0 to 0.4 percentage
differences. In road plan, 100% of the items in site
clearing and earthworks (Bill no. 2) have 0 percentage
differences, while 86% of the items in bill no. 3 (
drainage and culverts) have 0 percentage differences.
All items in bill no.4 (Pavement and surfacing) have 0
percentage differences between the manual and digital
computation. Since there are little or no difference in
the result obtained from manual computation and
digital computation. Therefore, the developed digital
computation program is efficient and reliable and can be
used in lieu of the manual estimation.
