Duration, or start and stop. A large change against a fixed end date means more people on the work and a higher burn rate. A change that stays undefined and keeps coming back, such as an alternative option, keeps costing hours every week.
Consultants, meetings, shareholders, quality review. Designers assume coordination is just part of the job. Every report written, every meeting attended, and every drawing reviewed charges to the project.
Increase in area, higher level of design, services not named in the contract. This is the easiest factor to define, because the contract states the scope. Compare the request to what is written.
Say yes to the person before you answer the request. You have refused nothing, and you have promised nothing.
This buys you the time to do the homework. Never price a change in the room from memory.
Specific, and unapologetic. Lead with time. Time is the unit a client already understands.
Yes or no, the answer is fine. Close the same way either time: “Of course. Let me know if you need anything else.”
| The Situation | Say It Like This | Watch Out For | |
|---|---|---|---|
| 01 | In a design meeting, the client asks to see an alternative option. | “Happy to look at that. Let me confirm what the option takes on our end, and I will come back with the time and the fee.” | An ask that never gets defined and returns every week. This is the most common source of uncounted hours in design. |
| 02 | The client adds area to the program. | “That takes us from 40,000 to 46,000 square feet. Let me price the added work so you can decide before we build on it.” | Treating area as a small change. Area drives every downstream sheet and every consultant. |
| 03 | The client expects a higher level of design than the agreement includes. | “The agreement covers design development. What you are describing is closer to construction documents. Here is what that difference costs in time.” | A level of design nobody wrote down. If the contract is vague, fix the contract, not just this one change. |
| 04 | The client asks for an extra report, meeting, or review cycle. | “We can add that review. It adds roughly 16 hours of coordination across three consultants. Would you like to add it?” | Coordination treated as free. It is real time, and it is already charging to the project. |
| 05 | The change is large and the end date will not move. | “We can hold the date. Holding it takes two more people, and here is that cost. The other path is a three week extension at no added fee. Which do you want?” | Quietly staffing up. The burn rate climbs and the margin drops before anyone reports it. |
| 06 | The change is small, below the threshold worth an ask. | “I have logged this one so we both see it. These are adding up. When they reach the threshold, I will bring you an additional service request.” | A dozen small changes nobody logged. The first ask then carries all of them, and it surprises the client. |
| 07 | The client pushes back on the price. | “I understand. The number is built from the hours the change takes, and here is the buildup. If it is too high, we can reduce what the change includes.” | Defending a number you cannot break down. Without the buildup you cannot hold the price. |
Estimate the change as a fraction of a full time person across the affected period. Fastest method, and the right one when the change is driven by schedule.
Estimate time per square foot for each sheet the change touches, then add a markup for engineering coordination where it applies.
Build the change the same way the fee was built. Slowest method, and the strongest one when the client asks to see the buildup.
