The Drawing Gaps That Keep Generating RFIs on Remodel Projects

Most RFIs on remodel projects are not surprises. They come from the same categories of missing information, over and over.

The field hits a condition the drawings did not address. Work stops while someone tracks down the designer. The schedule slips — a little, or a lot, depending on where the gap landed.

The frustrating part is that most of these gaps are findable before the set goes out. They require a focused review, not a full redesign. The categories below are the ones that come up repeatedly in remodel work.

---

Missing or Assumed Existing Conditions

Remodel projects start with existing structure, existing finishes, existing rough-in, and existing dimensions that may or may not match what the drawings show. When the drawing set does not document what is actually there, the field has to figure it out.

Common gaps:

• Wall thicknesses shown as assumed rather than field-verified
• Ceiling heights noted as existing without confirmation
• Structural members shown in plan but not confirmed in section
• Plumbing rough-in locations assumed from original permit drawings, which may not reflect as-built conditions

Remodel-specific conditions that often go undocumented: soffits that affect cabinet height, out-of-plumb walls that shift finish dimensions, and floor buildup at transitions between old and new tile. These are easy to miss during design and expensive to resolve in the field.

The pre-issue check here is straightforward: flag every note that says "existing" or "verify in field" and ask whether the answer to that verification actually matters for the work. If it does, get the information before the set goes out.

Dimensions That Do Not Add Up

Dimension strings that do not close, or that conflict between plan and elevation, are a consistent source of field questions on remodel sets.

This happens because plans, elevations, and schedules are often drafted at different times and not cross-checked before issue. A plan gets dimensioned. An elevation gets dimensioned separately. No one confirms they agree.

Common gaps:

• Overall dimension does not match the sum of the string
• Plan dimension conflicts with elevation dimension for the same condition
• Rough opening size shown in plan does not match the window or door schedule
• Cabinet run dimensions do not account for filler or end panel thickness

A dimension audit does not need to be exhaustive. Checking the critical runs — the ones that affect framing, rough-in, or cabinet layout — catches most of the problems.

Undefined Transitions and Edge Conditions

Remodel drawings tend to be detailed at the center of the design and vague at the edges. The transition between new work and existing work is where the field most often has to stop and ask.

Common gaps:

• No detail showing how new flooring meets existing flooring at a doorway or threshold
• New wall height shown, but no note on how it terminates at an existing ceiling that is not level
• New tile shown in plan, but no detail on how the field edge is handled at a tub or shower curb
• Patch scope not defined where new work meets existing drywall

These conditions are easy to overlook during design because the designer is focused on the new work. A review that specifically asks "what happens at every edge where new meets existing" will surface most of them.

Conflicting Notes Between Drawings and Specifications

When a drawing note says one thing and the specification says another, the field has to stop and ask which one governs. On smaller remodel jobs, a formal spec package may not exist at all — but even a finish schedule or a scope narrative can conflict with what is shown on the drawings.

Common gaps:

• Finish schedule calls out one product; drawing note calls out a different one
• Drawing shows a detail that conflicts with a spec section requirement
• Scope of work in the spec includes an item not shown on any drawing
• Drawing note references a detail that does not exist in the set

A cross-check between the finish schedule, the drawing notes, and any written scope or specification for the primary trades will catch most of these before they become RFIs.

Scope Boundaries That Are Not Drawn

On remodel projects, the line between what is in scope and what is not in scope is often described in the contract but not shown on the drawings. When the field encounters a condition that sits near that line, they have to ask.

Common gaps:

• Demolition extent not shown on plan, only described in the scope narrative
• Patch and repair scope not defined after demolition
• Existing fixture or equipment removal not shown or noted
• Work by owner versus work by contractor not clearly delineated on the drawings

A scope boundary review asks: is every item in the scope narrative represented somewhere on the drawings? If the answer is no, a note or a simple demo plan can close the gap.

---

A Simple Pre-Issue Review Structure

A targeted review before the set goes to the field does not need to be long. For most remodel projects, a focused pass through these five categories takes less time than responding to the RFIs they would have generated.

The review works best when it happens after the drawing set is substantially complete but before it is issued for construction — and when it is owned by whoever is responsible for drawing coordination, whether that is the designer, a production partner, or the project manager.

This is not a full constructability review. It is a gap check focused on the categories that generate avoidable RFIs.

The Practical Upside

Fewer RFIs means less idle time on site and fewer interruptions to the design team. It also means the project moves closer to the schedule that was bid.

The review does not require a redesign. It requires someone to look at the right things before the set leaves the office.

For remodelers who want cleaner drawing sets before work starts, Creo's contractor partnership support is built around this kind of pre-construction production and drawing coordination work.
