Adaptive Reuse Clinic: Programming Gaps in a 1920s Warehouse

Missing information falls into four buckets: life safety, structure, building systems, and patient access. Life safety includes the existing egress path, dead-end conditions, fire-resistance of the heavy timber, and whether the occupancy will be classified as business or ambulatory health care. Structure includes the slab-on-grade capacity for the 2,500 lb imaging machine and the mezzanine live-load capacity; the unknown slab capacity is a go/no-go item because imaging cannot be placed on an upper floor without verified reinforcement. Building systems include available electrical capacity, HVAC capacity, plumbing for exam rooms and lab sinks, and medical gas needs. Patient access includes an accessible route from the public way, parking and drop-off counts, ambulance access, and signage. The designer should prioritize life safety and structure first, because they can invalidate a layout after weeks of work. Hazardous-materials survey and accessibility route come next, then MEP capacity. The program also needs operational detail: exam-room turnover, provider-to-room ratio, lab equipment list, and pharmacy storage. A written data-gathering plan with owners of each item, due dates, and decision deadlines keeps the 9-month schedule realistic.

A quick net-area check suggests the program fits in 18,000 sf, but not in the shape the client imagines. Using planning assumptions of 100 nsf per exam room, 120 nsf per provider office, 300 nsf lab, 400 nsf imaging, 300 nsf pharmacy, and 12 nsf per waiting occupant, the net program is roughly 2,200 + 720 + 300 + 400 + 300 + 720 + reception 200 + staff support 1,200 = about 6,040 nsf. At a 65 percent net-to-gross efficiency for a clinic with long corridors and thick walls, gross need is roughly 9,300 sf. That leaves area, but the 20 ft column grid and the mezzanine constrain usable bays. Six offices on the exterior wall consume about 60 linear ft, which is available, but putting all exam rooms on the exterior is not necessary and would waste perimeter. Better strategy: create exam pods in the deep bay, with two rooms sharing a provider alcove; place imaging on grade near the dock for delivery and shielding; keep waiting and reception near the accessible entrance; use the mezzanine for staff support, files, and mechanical, not exam rooms, because 11 ft clear is tight and the structural capacity is unverified. The client should trade window offices for a smaller number of shared offices and borrow daylight into the open provider area.

First, the loading dock is the only accessible entrance. That conflicts with patient dignity, wayfinding, and separation of clean and soiled traffic. The plan must create a new accessible patient entrance from the street side, with a level landing, automatic door, and direct route to reception; the dock remains for deliveries and imaging equipment. Second, truck noise at the dock affects exam rooms and the waiting area. The functional plan should put exam pods away from the dock, use the staff support zone and mechanical room as a buffer, and specify acoustic seals and a vestibule at the dock. Third, the unknown structural capacity and the mezzanine affect where the imaging suite can go. Imaging belongs on grade, near the dock for equipment delivery, but not against the noisy dock wall; it needs a shielded room, vibration isolation, and verified slab capacity. If the slab cannot take the load, the program must either reinforce the slab or relocate imaging to a new addition. The accessible parking and drop-off count also must be verified against local code before the site plan is frozen; a clinic with 180 patients per day can fail operationally if drop-off queuing blocks the street.
