Estimating in Building Construction

(Kalthiya AryanmXZGQq) #1

Every item on this page is supported by workup sheets. A
spreadsheet version of Figure 4.7 (Recap.xls) is provided on
the companion disk.
In addition to summarizing portions of the project, it is
helpful to summarize the entire estimate onto a single page.
Figure 4.8 is an example of a summary sheet that could be
used to summarize all costs for the entire project. A spread-
sheet version of Figure 4.8 (Est-Summary.xls) is provided on
the companion disk.
The summary sheet should list all the information
required, but none of the calculations and sketches that were
used on the workup sheets. It should list only the essentials,
yet still provide enough information for the person pricing
the job not to have to continually look up required sizes,
thicknesses, strengths, and similar types of information.


4–11 Errors and Omissions


No matter how much care is taken in the preparation of
the contract documents, it is inevitable that certain errors
will occur. Errors in the specifications were discussed in
Section 3–12, and the same note-taking procedure is used
for all other discrepancies, errors, and omissions. The
instructions to bidders or supplementary general condi-
tions ordinarily states that if there are discrepancies, the
specifications take precedence over drawings and dimen-
sioned figures, and detailed drawings take precedence over
scaled measurements from drawings. All important discrep-
ancies (those that affect the estimate) should be checked
with the architect/engineer’s office.
