Healthcare & Medical Casework Shop Drawings: What Every Set Must Include

Healthcare casework is one of the most demanding millwork categories a fabricator can take on. A nurse station isn't just a counter with cabinets — it's a safety-critical assembly that must satisfy ADA dimensional standards, infection-control material requirements, electrical and data rough-in coordination, and a submittal review process that often involves the owner's facilities department, the infection control officer, and the architect all commenting on the same drawing set.

I've worked on dozens of healthcare casework packages, from single-exam-room renovations to multi-floor hospital fit-outs. The difference between a smooth approval and a rejection letter almost always comes down to how thoroughly the millwork shop drawings document the compliance items — not the geometry, which is rarely the problem.

What Healthcare Casework Includes

Medical casework spans a wide range of built-in work. In a typical hospital or clinic project, the millwork scope includes:

• Nurse stations — transaction counters, sit-stand work surfaces, base and overhead storage, medication prep areas
• Exam room casework — wall-mounted overhead cabinets, base cabinets, exam table surround trim, hand-wash sink base
• Clinical lab casework — chemical-resistant counters, fume hood surrounds, under-counter storage, knee clearance cutouts
• Patient room millwork — bedside tables, over-bed tables, wardrobe units, nurse server pass-through cabinets
• Staff break rooms and kitchenettes — requiring NSF/ANSI 2 certification for food-contact surfaces in cafeteria prep areas
• Reception and waiting areas — transaction windows, ADA-accessible transaction surfaces, built-in seating

Each category has its own compliance requirements. The drawings must make all of them legible to the fabricator, installer, and reviewing architect simultaneously.

ADA Compliance Requirements for Healthcare Casework

ADA 2010 Standards are non-negotiable on any federally funded or publicly accessible healthcare project. For casework, the critical dimensions are:

• Accessible counter height: 34" AFF maximum for any surface designated as an accessible transaction surface or work counter
• Knee clearance at accessible workstations: 27" minimum height × 30" minimum width × 19" minimum depth — required at any position where a seated user is expected to work
• Forward reach range: 15"–48" AFF for accessible storage — overhead cabinets mounted too high don't comply
• Side reach range: 9"–48" AFF with 10" maximum reach depth, 48" maximum if reach depth is 10"–24"
• Approach clearance: 30" × 48" clear floor space in front of accessible positions, positioned for parallel or forward approach as required

Every accessible position must be explicitly dimensioned and labeled on the shop drawings. "ADA compliant" as a general note is not sufficient — reviewers want to see the actual dimensions documented at each unit.

Infection-Control Surface Materials and How to Document Them

Infection control is where healthcare casework diverges most sharply from standard commercial millwork. The materials, joints, and hardware must all support cleaning with hospital-grade disinfectants — including quaternary ammonium compounds and bleach solutions that degrade standard wood finishes quickly.

Common infection-control surface specifications include:

• High-pressure laminate (HPL) — standard on most healthcare casework. The drawing must specify: HPL grade (horizontal vs. vertical), edge treatment (same HPL edge banding, no exposed particleboard edges), and the requirement for no exposed seams at sink cutouts
• Solid surface counters (Corian, Avonite, or equal) — required at all sink positions. Note the integral coved backsplash requirement — no gap between counter and wall where bacteria can accumulate
• Phenolic resin panels — specified for high-splash or wet zones; chemically resistant and non-porous. Call out panel thickness (typically 1/2" or 3/4") and mounting method
• Cabinet interiors — must specify melamine-lined interiors rather than raw particleboard or plywood; often requires antimicrobial additive in the substrate resin
• Hardware — specify push-to-open or sensor-actuated mechanisms for touch-free operation in isolation rooms; antimicrobial pulls (copper alloy or coated) where manual operation is required

The drawing must call these out unit-by-unit. A materials legend at the top of the sheet is helpful, but each unit elevation must still reference it explicitly so there's no ambiguity during fabrication.

Modular Steel vs. Built-In Wood Casework: What the Drawings Cover

Healthcare projects frequently mix two casework systems: modular metal casework (Haskell, Herman Miller, Intellect) and traditional wood-frame built-in millwork. Both appear on the same architectural drawings — and both often appear in the same millwork submittal package.

Modular metal casework comes from the manufacturer with its own product data sheets and installation instructions. The millwork shop drawings cover the built-in wood work: custom nurse station transaction counters, reception desks, built-in seating, and architectural millwork that ties the modular system into the surrounding space.

When the two systems interface — which they always do at transitions between modular base cabinets and custom wood upper cabinets, or between a prefab nurse station and a custom transaction counter cap — the shop drawings must show the exact joint: how the wood counter cap sits on the metal base, what the finish reveal is, and how the scribe strip handles out-of-plumb walls.

MEP Rough-In Coordination in the Drawings

Healthcare casework drawings require more MEP coordination than almost any other millwork category. Before fabrication, the drawings must document:

• Electrical rough-ins: outlet height and location in nurse station base cabinets for computers, monitors, and medical equipment; dedicated circuit notes where required
• Data and communications: conduit stub-out locations and cable management routing inside the casework — nurse stations typically have 4–8 data ports per workstation position
• Medical gas: oxygen, vacuum, and compressed air valve rough-in heights and horizontal offsets from unit centerlines, per the plumbing drawings
• Plumbing: sink drain stub-out height and horizontal location; hot/cold supply stub-out; P-trap clearance with base cabinet floor requirements
• Under-counter equipment: under-counter refrigerator rough-in dimensions (note: many medical-grade under-counter fridges require 1" clearance on all sides and a dedicated circuit)

The standard practice is to overlay the casework plan view onto the MEP rough-in plan and identify every conflict in the submittal. The GC needs to see that the fabricator has checked the coordination — not just built the casework to the architectural drawings and hoped the rough-ins line up.

Drawing Set Requirements: What to Include

A complete healthcare casework shop drawing package includes:

• Floor plan — room layout with each casework unit labeled and keyed to the unit schedule; MEP rough-in overlays for coordination verification
• Elevations — front elevation for every unit at minimum 1/2"=1'-0" scale; larger scale sections for complex units
• Sections and details — wall connection details, counter-to-base transitions, scribe details for out-of-plumb walls, ADA knee clearance sections
• Unit schedule — table listing each unit with: dimensions (W×H×D), material spec, hardware schedule, ADA compliance status, rough-in requirements
• Materials legend — substrate, door/drawer front material, edge banding, hardware finish, counter material — all keyed to manufacturer and product number where specified
• Accessibility diagrams — dimensioned diagrams showing compliance at each ADA position, with code references

Some hospital facilities departments require a separate "infection control clearance" sheet summarizing all surface materials and cleanability specs. If the project spec includes this requirement, it should be addressed in the submittal package.

Common Submittal Review Comments on Healthcare Casework

After years of healthcare casework submittals, these are the comments I see most often:

• "ADA dimensions not documented" — add explicit knee clearance and reach range dimensions at every accessible position
• "Counter material not fully specified" — "solid surface" is not enough; specify manufacturer, color, edge profile, and backsplash treatment
• "MEP rough-in coordination not shown" — add overlay plan or note sheet confirming electrical/plumbing stub-out locations match the drawings
• "Hardware not antimicrobial" — project spec requires antimicrobial hardware; revision needed with confirmed product numbers
• "Phenolic panel joints not detailed" — show how adjacent panels join at inside corners (butt joint with sealant vs. metal trim vs. full-height continuous panel)

Each of these is a revision cycle that delays fabrication. Getting them right in the first submittal requires understanding what healthcare reviewers look for — not just what the architectural drawings show. Our millwork drawing rates reflect the additional coordination time that healthcare projects require.
