A medical office building (MOB) in Beaverton operates under federal ADA accessibility obligations, with the local healthcare-system context shaped by the Providence St Vincent corridor MOBs, the Kaiser Beaverton facilities, and the private MOB cluster serving the Nike-corridor workforce. The 2010 ADA Standards for Accessible Design, Section 406, set the slope, width, landing, and detectable-warning requirements for every curb ramp on an accessible route. Cojo installs ADA-compliant curb ramps at Beaverton Washington County MOBs, and this guide explains how to scope the work so the project closes inside the after-hours window.
ADA 2010 Section 406, Field-Ready Spec
Section 406 sets a running slope of 1:12 maximum (8.33 percent), a cross slope of 1:48 maximum (2.08 percent), a ramp width of 36 inches minimum, and a level landing at the top of the ramp at least 36 by 36 inches. Flare slopes on the sides where they transition to the adjacent walking surface are limited to 1:10 (10 percent) maximum. Detectable warning surfaces (truncated domes) are required at the bottom of every ramp meeting a vehicular route -- they extend the full ramp width and 24 inches deep in the direction of travel.
The most common Beaverton MOB compliance failure is cross-slope drift on older ramps poured before 2010, when field cross-slope verification was less consistent. A digital-level field measurement during inventory walk catches this before the ADA demand letter arrives. See ADA curb ramp slope requirements for the field protocol.
Beaverton MOB Operating Constraints
Patient-access continuity drives every Beaverton MOB ADA scope. The MOB cannot detour patients away from accessible entrances during business hours; the contractor works after-hours or schedules around clinic-day-off windows. Providence St Vincent runs 24/7 emergency operations on its main campus, which adds ambulance-access-lane constraints to any ramp affecting those routes. Kaiser Beaverton and the larger private MOBs along Cedar Hills Boulevard run clinic hours that match the typical Monday-through-Friday schedule.
Washington County HIPAA-adjacent vendor vetting applies on most healthcare-system-affiliated MOBs. The facility manager will require insurance certificates, CCB license verification, and sometimes a vendor agreement acknowledging patient-area access restrictions. Cojo carries the required coverage and handles vendor onboarding up front.
Washington County and City of Beaverton Permitting
City of Beaverton permitting for ADA curb ramp installation depends on scope. A single-ramp replacement on an existing accessible route falls under a minor public-works permit. A multi-ramp project affecting pedestrian circulation may trigger a site-development review. Beaverton Public Works coordinates with Washington County and Clean Water Services on ramps interfacing with public right-of-way or stormwater.
For MOBs on a hospital campus, the campus master-plan ADA inventory drives the scope. Providence St Vincent, Kaiser Beaverton, and the larger private MOBs maintain field-measured inventories that streamline bid-document preparation.
Industry Baseline Range
| Project Type | Cost Per Ramp | Typical Project |
|---|---|---|
| Single ramp replacement (standard width) | $1,800 to $4,500 | $1,800 to $4,500 |
| Multi-ramp replacement (5 to 10 ramps) | $1,500 to $3,800 per ramp | $7,500 to $38,000+ |
| Ramp + adjacent sidewalk panel | $2,500 to $6,500 | $2,500 to $6,500 |
| Detectable warning retrofit (only) | $400 to $1,200 per panel | $400 to $12,000+ |
Current Market Reality
Beaverton MOB ADA scopes rarely land at baseline. After-hours premium labor, ambulance-access traffic-control at the Providence St Vincent campus, hidden sub-base conditions on older private MOBs along Murray Boulevard, Allen Boulevard, and Hall Boulevard, and concrete-cure waits all push the real number up. High-early-strength concrete mixes get the ramp back into service in 24 to 48 hours but add 15 to 30 percent to the concrete line item.
Phasing Around Clinic Operations
Most Beaverton MOBs operate Monday-through-Friday clinic hours with reduced weekend coverage. The Nike-corridor workforce concentration drives midweek lunch-rush patient volume at urgent-care and walk-in clinics. The cleanest phasing window is Friday evening through Sunday afternoon. High-early-strength concrete mixes make this single-weekend window workable for single-ramp scopes. Multi-ramp projects at the Providence St Vincent campus or larger MOB campuses phase across several weekends.
Cojo's concrete services handles the ramp installation, with related Beaverton parking lot striping for ADA accessible stall layout, accessible-aisle painting, and ADA signage post-install. The Oregon asphalt paving cost baseline covers parking-lot scopes including both asphalt and concrete work.
What the Practice Manager and MOB Operations Lead Decide
The buyer at a Beaverton MOB is usually the practice manager (single-tenant MOB) or the MOB operations lead (multi-tenant MOB). Three levers move cost: scope (single ramp, full inventory, or partial), schedule (single weekend or multi-weekend phasing), and concrete mix (standard cure or high-early-strength). For an active ADA complaint, the high-early-strength mix wins on the schedule lever despite the premium.
For MOBs that are part of a campus ADA upgrade, bundling the curb ramp work with parking-lot restripe per hospital and medical office striping discipline reduces mobilization overhead by 10 to 15 percent. Most Beaverton healthcare-system MOBs run their ADA upgrade cycles as part of broader campus capital plans, which makes the bundled scope the more common contract structure.
Common Failure Patterns Found at Site Walks
A site walk of an existing Beaverton MOB accessible route usually surfaces three failure patterns. The first is cross-slope drift -- a ramp poured before 2010 may now read above the 2.08 percent maximum because of clay-soil settlement under the slab. The second is detectable-warning panels that have lifted, cracked, or worn through to the point where the truncated-dome surface no longer functions for cane-detection. The third is flare-slope drift at the side transitions, which creates a tripping hazard.
Catching these failures at the walk-through stage and addressing them in a single bundled scope reduces mobilization overhead and gets the campus current with the 2010 Standards in one capital event. Providence St Vincent, Kaiser Beaverton, and other major Beaverton healthcare-system MOBs typically run ADA transition-plan refreshes on a 5-to-7-year cadence, with the campus inventory at refresh time usually identifying 5 to 15 ramps in this combined failure pattern -- enough volume to make a single multi-ramp mobilization the most cost-effective approach.

Every Beaverton MOB curb ramp scope sits on its own combination of existing-condition compliance gap, patient-access constraint, and after-hours phasing window. The only way to land an accurate number is a site walk with field measurement of every ramp on the accessible route. Cojo is CCB licensed and insured and has installed ADA curb ramps at MOBs across Washington County from the Providence St Vincent corridor to Kaiser Beaverton to private clinics along Cedar Hills Boulevard.
