Sheet 01 · Built For What Repeats Across Every Floor

ONE MISSED CONFLICT ON A TYPICAL UNIT PLAN. MULTIPLIED BY EVERY FLOOR THAT REPEATS IT.

Multifamily construction document review is an independent, owner-side check of the issued set for an apartment, condo, or mixed-use residential build — run by reviewers who understand what makes this asset class different: a typical unit plan repeated across dozens of floors, a podium transition from concrete parking or retail into wood-frame construction above, and demising-wall fire ratings that have to hold consistently unit to unit. A single missed conflict here rarely stays isolated — it's built into every floor that reuses the same plan.

Why Multifamily Sets Carry More Risk

EVERY OTHER ASSET CLASS BUILDS ONE FLOOR PLAN. THIS ONE BUILDS IT DOZENS OF TIMES.

A standard construction document review checks submittals, spec-to-drawing alignment, code compliance, and MEP coordination — and a multifamily set needs every bit of that. What's different is what repetition does to a missed conflict: a wet wall that's misaligned, an electrical panel that doesn't fit, or a fire-rated assembly that's drawn wrong on the typical unit plan doesn't stay a single-unit problem. It's built into every floor that reuses that plan, on top of a podium transition and a fire-rating stack that both have to hold consistently unit to unit.

Repeated Unit Plans Multiply Every Miss

A conflict on the typical unit plan isn't a single error — it's built into every floor that repeats it.

Podium-To-Wood-Frame Transition

Wood-frame stories over a concrete podium create a structural and MEP transition point spanning two construction types.

Fire-Rated Separation, Unit To Unit

Demising walls, corridors, and shaft enclosures carry ratings that have to hold consistently across every repeated unit type.

What Gets Checked On A Multifamily Set

EVERY SHEET, INCLUDING THE FLOOR YOU'RE ABOUT TO REPEAT.

The issued set is read once, in full, by reviewers who've drawn these sets themselves — not a keyword search, not a single-discipline pass. On a multifamily set, four things get checked specifically:

TYPICAL UNIT PLAN

The wet wall, electrical, and HVAC layout on the typical unit checked thoroughly — whatever's wrong there is wrong on every floor that repeats it.

VERTICAL MEP STACKING

Plumbing stacks, electrical risers, and HVAC shafts checked for alignment floor to floor through the repeated unit plan.

PODIUM TRANSITION

Structural and MEP continuity checked where wood-frame construction lands on the concrete podium below.

FIRE-RATED ASSEMBLIES & CODE

Demising wall, corridor, and shaft fire ratings checked for consistency sheet to sheet, unit to unit.

The output is a written findings report — every conflict located by sheet and detail, severity-ranked (High/Med/Low), with an estimated dollar exposure and schedule impact on each — plus a live walkthrough meeting.

Where This Sits

SAME GOAL AS YOUR OTHER CHECKS. READ FLOOR BY FLOOR, NOT JUST ONCE.

vs. Architect QC

DESIGN INTENT VS. OWNER'S INTEREST

The architect's QC checks the set against design intent. This review is paid by the owner and reports to no one else — run alongside QC, not instead of it. What owner-side QA/QC actually means →

vs. GC Coordination Review

PRICING THE WORK VS. FLAGGING THE RISK

The contractor's coordination review is scoped to pricing the work accurately. This review is scoped to surface exposure for the owner, in writing, before it's priced or built. GC's reading this — see why it's not an audit of your work →

vs. BIM Clash Detection

ONE MODELED FLOOR VS. EVERY ISSUED SHEET

Clash detection often runs against one modeled floor plate, copied to every level it repeats on — which assumes the model matches the issued sheet on every floor. This review reads the actual issued documents for each level. Full comparison →

Preempt Global also gets compared against clash-list and checklist software directly: see vs. RediCheck, vs. LightTable AI, and vs. CHECKSET.

Why This Matters

the cost of skipping it, across the industry

$177 billion

yearly cost of un-coordinated construction items

3-5 weeks

avg. schedule delay per commercial project

12%

of total project budget goes to change orders

76%

of projects fall behind schedule due to poor QA/QC

A clash caught in a construction document review costs one redline and five minutes. The same conflict caught in the field averages $18,400 and a 12-day schedule slip — and on a repeated unit plan, that redline gets multiplied by the floor count instead of staying isolated to one unit. If your project has a typical plan reused across multiple floors — any size, no minimum construction value — that's the gap this review is built to close.

The Guarantee

$50K IN EXPOSURE, OR THE REVIEW IS FREE.

If a multifamily construction document review doesn't surface at least $50,000 in documented cost exposure, you don't pay for it — no partial credit, no fine print, on every pricing tier. On a set with this much repetition, there's always something to find, which is why it's put in writing before it's built into every floor.

Before You Ask

STILL GOT QUESTIONS?
HERE'S THE STRAIGHT ANSWER.

What makes multifamily construction document review different from a standard construction document review? +

The method is the same — an independent, owner-side check of the issued set. What's different is repetition: a typical unit plan gets built dozens or hundreds of times across a project, so a missed conflict in a wet wall, an electrical panel, or a fire-rated assembly on that plan isn't a single error — it's built into every floor that reuses it.

Why does a repeated unit plan matter so much to this kind of review? +

Because catching a conflict once, on the typical unit plan, before it's built, prevents it from repeating on every floor that shares that plan. Catching the same conflict after three or four floors are already framed means fixing it that many times over, plus the units already built.

What's a podium transition, and why does it need its own check? +

Many multifamily projects stack wood-frame construction on top of a concrete podium deck holding parking, retail, or amenity space. That transition is where structural systems, plumbing stacks, and electrical risers have to align across two different construction types built by different trades — a common place for a conflict to hide.

Does this replace the fire-rating and life-safety review already built into permitting? +

No. Permit plan review confirms code compliance on its own timeline and scope. This review runs earlier, on the issued design set, reading demising walls, corridors, and shaft enclosures for the same fire-rating consistency across every repeated unit type — before a conflict reaches a plan reviewer or the field.

Who typically orders this — the owner, the developer, or the GC? +

The owner or the owner's rep — often the developer's own capital projects or asset management team on a multifamily build. It's paid by the owner and reports to no one else. See the full breakdown built for owners →

What kinds of multifamily projects need this? +

Garden-style, podium, and high-rise apartment or condo projects, and mixed-use residential builds with ground-floor retail or parking — any set with a repeated unit plan and multiple trades sharing tight coordination. There's no minimum construction value.
