A painting contractor is reviewing a change order request from a client. The original scope included painting all interior walls with a standard latex paint. The change order now specifies a high-performance epoxy coating for a specific area, requiring specialized surface preparation (abrasive blasting) and a longer cure time between coats. How should the contractor primarily assess the impact of this change on the original bid?
- AAdjust the labor hours solely based on the increased application time for epoxy.
- BRecalculate only the material cost difference for the epoxy coating.
- CPerform a comprehensive re-estimation of all affected direct and indirect costs, including new equipment, specialized labor, and extended project duration.
- DApply a standard percentage increase to the original bid amount for any change order.
Show answer & explanationAnswer & explanation
Correct answer: C. Perform a comprehensive re-estimation of all affected direct and indirect costs, including new equipment, specialized labor, and extended project duration.
A change from standard latex to high-performance epoxy with specialized surface preparation and longer cure times impacts material costs, labor rates (specialized skill), equipment (abrasive blasting), and project duration (cure times), which in turn affects project overhead. A comprehensive re-estimation is crucial to capture all these interconnected cost implications.
Why the other options are wrong
- A. Labor hours are affected, but so are the type of labor, equipment, and overall project duration/overhead.
- B. Material cost is only one component; specialized prep, labor, and time are also affected.
- D. A 'standard percentage increase' is insufficient for a complex change that alters multiple cost categories significantly.
Change Order Impact Assessment
The process of thoroughly evaluating how a modification to the original project scope affects all aspects of the contractor's costs, schedule, and resources.
- Requires re-estimation of direct costs (labor, material, equipment).
- Includes indirect costs (project overhead, supervision, extended duration).
- Must be detailed to avoid financial loss or disputes.
Memory trick: Change orders ripple through ALL costs, like a stone in a pond.
