Hillsboro's hospital footprint anchors on Tuality Healthcare (now part of OHSU as OHSU Hillsboro Medical Center) and Kaiser Westside Medical Center on the city's south side. Each campus runs its own ambulance-access lane, ADA path-of-travel network, and patient-flow pattern. This article walks through what facilities directors and patient access services leads at Hillsboro hospital campuses should expect on scope, scheduling, and cost for ADA curb-ramp installation.
ADA 2010 Section 502: The Hard Standard
ADA 2010 Standards for Accessible Design Section 502 governs accessible parking and the access aisle. For hospital campuses, the binding parts are:
- Minimum stall counts: 1 van-accessible per 6 accessible stalls (with at least 1 van-accessible per lot).
- Access aisle width: 5 feet for car-accessible, 8 feet for van-accessible.
- Stall and access aisle slope: 1:48 max in any direction (roughly 2 percent grade).
- Curb-ramp slope: 1:12 max (roughly 8.33 percent) on the ramp run.
- Detectable warning surface: per Section 406, on the ramp transition to the vehicle-way.
OHSU Hillsboro Medical Center and Kaiser Westside both run more generous accessible-stall counts than the bare minimum because the patient population includes a high mobility-impaired load. Each facilities planning team carries an ADA self-evaluation that lists every non-compliant ramp and stall on the campus, prioritized by patient-traffic exposure. For broader Hillsboro ADA scope context, our Hillsboro ADA curb-ramp work coverage walks through the city-wide service area. For design background, see our ADA curb-ramp slope reference.
FGI Guidelines and the Health-Facility Overlay
The Facility Guidelines Institute (FGI) Guidelines for Design and Construction of Hospitals are the binding healthcare-facility standard adopted by reference in Oregon hospital construction code. The FGI Guidelines layer additional requirements on top of ADA: minimum unobstructed pedestrian path widths through ambulance-access zones, lighting standards on accessible routes, and ramp-protection details where vehicle traffic conflicts with pedestrian flow. A standard commercial ADA ramp does not always meet FGI Guidelines; a hospital ramp does.
Ambulance-Access Lane Preservation
The single hardest constraint on Hillsboro hospital ADA work is the ambulance-access lane. Every ED entrance has a designated ambulance-access lane that has to stay operational 24/7. OHSU Hillsboro Medical Center serves as the primary Washington County emergency department for the central Hillsboro service area. Kaiser Westside's ED handles Kaiser-member ambulance arrivals across the broader Westside corridor. ADA curb-ramp work on or near those lanes happens in night-shift work windows (usually 10pm to 6am) with phased lane closures and active traffic management. The hospital security or facilities team coordinates each phase with EMS dispatch. Skipping that coordination is the fastest way to lose hospital trust on a project. For complementary fleet-yard scope context, our Hillsboro fleet-yard paving coverage walks through the adjacent procurement pattern.
Patient-Flow Continuity and Construction Phasing
Hospital campuses run on continuous patient flow. The standard phasing playbook:
- Map every ADA path-of-travel through the affected zone.
- Designate a temporary ADA-compliant alternate route before any construction starts.
- Post wayfinding signage in English and Spanish (and other languages as the campus patient demographic requires).
- Coordinate with patient transport, valet, and shuttle services on the new route.
- Run the construction in 2-to-4-day phases with full restoration at the end of each phase.
The temporary alternate route has to meet ADA Section 502 compliance on its own. That sometimes means installing a temporary modular ramp as part of the project mobilization.
Industry Baseline Range for Hillsboro Hospital ADA Curb-Ramp Work
Pricing depends on ramp complexity (single, perpendicular, parallel, combination), detectable warning surface type, drainage tie-in, and night-shift premium.
Industry Baseline Range
| Scope | Cost Per Ramp | Typical Cluster Total |
|---|---|---|
| Single ADA curb ramp (standard) | $2,500 to $5,400 | $2,500 to $5,400 |
| Perpendicular ramp with truncated dome panels | $3,000 to $6,400 | $3,000 to $6,400 |
| Combination ramp (corner radius) | $4,400 to $8,800+ | $4,400 to $8,800+ |
| Full ED-entrance ADA path with drainage tie-in | $8,800 to $25,000+ | $8,800 to $25,000+ |
| Night-shift premium | +20 to +40 percent | varies |
Current Market Reality
Hillsboro hospital ADA curb-ramp work in 2026 trends toward the upper portion of the published baseline. Concrete and truncated-dome-panel material costs rose roughly 20 percent through 2024-2025. Night-shift premium and after-hours coordination add 20 to 40 percent to a daytime baseline. The Washington County wet-season pattern compresses the workable construction window: concrete cures slower in cool damp weather, which extends the closure period each phase. A standard perpendicular ADA ramp with truncated dome panels at the OHSU Hillsboro Medical Center ED that bid at $3,800 in 2019 commonly bids at $5,200 to $6,200 today. For broader cost context that stacks with the ADA ramp line, see our Oregon asphalt cost benchmarks.
Detectable Warning Surfaces (Section 406)
ADA 2010 Section 406 requires a detectable warning surface (typically a truncated-dome panel) at the ramp-to-vehicle-way transition. The hospital-grade choice is a cast-in-place or surface-applied panel that meets the 50-percent visual-contrast requirement against the surrounding concrete or asphalt. The two main practical choices:
- Cast-in-place panels: installed during the concrete pour. Longest service life but more expensive at installation.
- Surface-applied panels: bolted or adhesive-bonded after cure. Lower upfront cost but more frequent replacement.
Most Hillsboro hospital campuses default to cast-in-place for new installations because the long-term replacement cost on surface-applied panels at high-traffic ED entrances stacks up over a 15-year horizon.
Procurement and Scheduling
OHSU Hillsboro Medical Center routes some projects through OHSU central procurement (with BOLI prevailing wage on most public-works contracts above the $50,000 threshold). Kaiser Westside runs its own Kaiser Permanente procurement. Schedule the work for the dry season (May through October). For broader concrete-service scope, see our concrete services page.
Talk to Cojo About Your Hillsboro Hospital ADA Project
If you are a facilities director, patient access services lead, or capital projects manager at OHSU Hillsboro Medical Center, Kaiser Westside, or another Hillsboro-area hospital, the next step is a campus walk and a scoping conversation. We will log each non-compliant ramp from the ADA self-evaluation, sequence the work to preserve patient flow and ambulance access, and price the scope against your capital cycle. To get the conversation started, start a Hillsboro hospital ADA scope and we will be on site within the week.
