For a $2,500,000 commercial project in Florida, what is typically the appropriate range for contingency allowance?
Correct Answer
B) 5-10%
For commercial projects, contingency typically ranges from 5-10% depending on project complexity, site conditions, and level of design completion. This covers unforeseen conditions and minor scope changes.
Why This Is the Correct Answer
The 5-10% contingency range is industry standard for commercial projects because it provides adequate coverage for unforeseen conditions, minor design changes, and construction uncertainties without being excessive. This percentage accounts for the complexity of commercial work while maintaining competitive pricing. For a $2.5M project, this translates to $125,000-$250,000, which is reasonable for handling typical construction contingencies. The range allows flexibility based on project risk factors such as site conditions, design completeness, and project complexity.
Why the Other Options Are Wrong
Option A: 1-3%
1-3% is too low for commercial projects and would only be appropriate for very simple residential work or projects with extremely detailed plans and minimal risk factors.
Option C: 15-20%
15-20% is excessive for typical commercial projects and would make bids uncompetitive; this high percentage might only be justified for highly complex projects with significant unknowns or experimental construction methods.
Option D: 25-30%
25-30% is unreasonably high for any standard commercial project and would indicate poor project planning or extremely high-risk conditions that would require special justification.
Memory Technique
Think 'Commercial = 5-10' - the word 'Commercial' has 10 letters, helping you remember the upper limit of the range.
Reference Hint
Look up contingency allowances in the project estimating or cost control sections of construction management references, typically found in chapters covering project budgeting and risk management.
