Construction Estimating Software
Why Not Excel?
"Spreadsheet Syndrome"
Organizations are often hesitant to use excel for complex calculations due to:
- perceived risk of programming errors
- belief that specialized software is inherently superior
Rebuttal
- Estimating software is doing very simple math under the hood.
- Commercial software is not without risk of bugs.
- Existing implementations hardly qualify as specialized.
The idea that specialized software ought to be preferred over monolith spreadsheets is well-founded, however, it is the case with construction estimating software that the proprietary options are functionally identical to a particularly involved workbook, except that they can not be modified to fit new use-cases.
Material Pricing
Apps generally assume users will utilize material pricing services like Supplier Xchange for precise pricing.
A Minimal Implementation
- Resolve Takeoffs
- Extend Items
- Labor Extension
