benchmarking
Benchmarking may be required to assess and verify the cost of a project by reference
to established costs for similar facilities. GSA has access to a number of tools useful to
estimators involved in benchmarking.
4 cost-estimating and cost-management tools
gsa cost estimating tools and spreadsheets
GCCRG
GSA developed the General Construction Cost Review Guide (GCCRG) to assist estimating in
the planning phase of new construction projects. Figure 2 is an example of a GCCRG estimate.
Project Cost Estimate (PCE)
The PCE was designed for programming and pre-design estimates. Applications may
include BERs, feasibility and program development studies, site acquisition and Market
Survey studies, and design. Figure 3 is an example of a PCE tool summary, Figure 4 is an
excerpt of a more detailed estimate sheet.
Building Life-Cycle Cost (BLCC) and Life-Cycle Cost (LCC) Spreadsheets
See Chapter 2, Section 2.2 for details.
cost-estimating systems
GSA encourages but does not require the use of computer-based cost-estimating programs
to mitigate manual calculation errors and facilitate changes. The requirements defined
in this document can be easily met by using various commercially available computer
software programs and spreadsheets. Generic spreadsheets allow user adaptation and
offer flexibility in applying different cost databases.
Figure 5 is an excerpt from a Uniformat-structured estimate report from a cost-estimating
system used at the design development phase. It illustrates the requirement to break down
unit prices into labor, materials, and equipment. The report uses the Uniformat levels to
organize the estimate and define the detail of the unit price items.
Figure 6 is an excerpt from a MasterFormat-structured estimate report developed at the
design development phase. It illustrates the requirement to break down unit prices into
labor, materials, and equipment.
