The order has a time box and a money box. You need both. You’re staring at the change order you printed an hour ago, the edges still crisp from your desk printer, a half-erased pencil mark next to the line that lists the client-requested deck extension. You’ve already run the material and labor numbers three times, but the time adjustment still feels off. No one warned you that small scope tweaks can bloat the timeline twice as fast as they bloat the budget, even when every cost line checks out on first pass.
This active change order draft
You already filled in the scope description: 120 square foot composite deck addition off the back of the ground-floor retail space, matching existing decking material and railing profile, with a 3-foot access ramp to connect to the existing sidewalk. You have material costs listed line by line: composite planks, hidden fasteners, pressure-treated support posts, concrete footings, UV-protective sealant, aluminum railing balusters, and ramp edging. You have labor costs listed just as clearly: two lead carpenters for 18 hours each, one entry-level laborer for 12 hours, one concrete pour technician for 4 hours, and one safety coordinator for 2 hours to oversee the footing pour. What’s missing is the formal entry for how many days this adds to your original critical path, and how that number ties directly to the dollar amount you’re requesting. A lot of change orders only list the cost adjustment, but you know that unaccounted for time adds hidden costs you can’t recoup if you don’t document them upfront: extended scissor lift rental, extended site general liability insurance, additional weekly site safety walkthroughs, even delayed mobilization for your next scheduled commercial remodel project 20 minutes across town. You can cross-reference your schedule overlaps directly in Draw Jacket if you need to confirm how the added work bumps up against your upcoming plumbing rough-in for the same site.
One line that shifts entire project trajectories
This is the line that explicitly ties days added to the dollar amount, separate from direct material and labor costs. Most people skip this line, or lump time-related overhead into a vague “contingency” line that clients push back on nearly 70% of the time, because they can’t see what the contingency covers, and assume it’s a markup you added to pad your profits. When you list the exact number of days added and the exact associated per-day overhead cost, you eliminate that pushback almost entirely, because you’re tying a concrete, measurable unit of time to a concrete, measurable cost that both parties can verify. Illustrative example: If your per-day project overhead runs $425, and the deck addition adds 3 full days to your critical path, you add a line for $1,275 explicitly labeled as 3 days of extended project overhead, separate from your direct material and labor costs. No vague language, no hidden fees, just a clear 1:1 tie between the time added and the dollar amount attached to that time. This line also protects you if the client requests additional small tweaks after this change order is signed, because you already have a documented per-day overhead rate that both parties have agreed to, so you don’t have to renegotiate that number every time a small scope adjustment pops up, like adding a set of planter mounts to the new deck railing.
Where you log both time and cost adjustments
Your change order has dedicated fields for all required data, and you’ll follow these steps to make sure time and cost are always paired, so no adjustment gets lost or questioned later:
- First, fill in the exact number of days added to the critical path in the designated time adjustment field, directly below the scope of work description. Do not round down to make the number look smaller; if the work adds 2.75 days, list 3 full days, because partial days still require you to carry overhead costs for the full day when they shift your critical path past a scheduled demobilization date, and you can’t split insurance or equipment rental costs across partial days for billing purposes.
- Next, enter the per-day overhead rate you use for all project work, and multiply it by the number of days added to get the total time-related overhead cost. Do not combine this number with your direct material or labor costs; keep it on its own line, labeled clearly so anyone reviewing the change order can immediately see the tie between the days added and the dollar amount, even if they’re only skimming the document for 10 seconds.
- Then, add a short note below that line explaining which critical path tasks are shifted by the added work: for the deck addition, that note might read “Time adjustment accounts for shifted concrete pour timeline, deck installation, and final city inspection scheduling, which delays scheduled interior demobilization by 3 days.” This note eliminates confusion later if the project timeline is questioned during the pay application review, or if the client asks why the overall project completion date moved back.
- Finally, add the total time-related overhead cost to your direct material and labor costs to get the full change order dollar amount, and enter that total in the designated final cost field at the bottom of the form. Double check that the number of days added is listed directly next to the total cost, so the two numbers are always paired when anyone reviews the document, no matter what section they’re looking at.
If your change order doesn’t have a designated time adjustment field, add it just above the cost breakdown section, in bold text so it’s impossible to miss. You don’t need to add extra pages or complex legal language, just a clear line that connects the two core values of the change order: time and money.
Next time you open this same change order page
You’ll be opening it after the client has signed off, right before you submit your next pay application that includes the change order amount. When you pull it up, first confirm that the number of days added matches the actual days the work took to complete, and that the total dollar amount matches the amount you’re requesting on the pay application. If the work took fewer days than you initially estimated because the concrete pour cured faster than expected, you can adjust the time-related overhead cost down to reflect the actual time spent, which builds trust with the client for future change orders, and reduces the chance of pushback on larger adjustments later in the project. If the work took more days than you estimated because of client-requested tweaks that happened after the change order was signed, like switching to a higher-end decking material mid-install that required a longer lead time, you can use the original signed per-day rate to draft a separate, small change order for the additional time, without having to renegotiate your overhead rate from scratch. You’ll also use this document to cross-reference your project schedule at the end of the job, when you’re reconciling all pay applications and change orders to make sure you’ve been compensated for all work completed. You don’t have to file it away in a physical folder you’ll never access again; keep it saved in your active project file so you can reference it whenever you need to confirm the agreed-upon timeline and cost adjustments for this scope of work, or if you need to reference the per-day rate for similar change orders on future retail buildout projects.
