Accessibility: No Ramps at Doors

According to the ADAAG, a manually operated door must have a five-foot flat (slopes at 2.1% or less) landing area.  The photograph shows original construction and a reversed ramp. The slope is in excess of 2.1%. To become compliant, the sidewalk will have to be replaced.  Zimmer Consultants photograph

Accessibility: Unique Signage

A unique signpost using tubular steel was observed at one of our projects. We did some investigation on installation and cost. An Internet steel supplier has 12” by 4” rectangular tubes in 10-foot lengths for $387 before tax and shipping. The Zimmer standard is a 2” by 2” square post inserted into […]

Accessibility: Parking Stalls, Over Doing It

We saw this accessible parking configuration in a Houston parking lot.  It is admirable to extend the accessible access-way behind the parking stall to extend the accessible route, but it is unnecessary.  The increased limits of accessible route mean the area must be leveled to less than a 2% slope […]

Accessibility: Parallel Curb Ramps

Even when detailed plans are provided and there is a project walk through, we find curb ramps are still incorrectly installed. At this installation, the ramp center should be flat (less than 2% slope). A flat area is necessary to allow for a wheelchair turning or maneuvering area. It is […]

Accessibility: A Long & Winding Route From A Bus Stop

We were at a mall with a series of short sidewalks with curb ramps connecting a bus stop with the shopping center building. It is inaccessible because the ramps are noncompliant, and the sidewalks between the ramps have cross-slopes greater than 2.1%. The sidewalk also gives the appearance of forcing […]

Signaled Crosswalks Also Known As Mid-Block Crosswalks

A few years ago, we designed and had a signaled crosswalk installed at a crosswalk “hidden” by curves in the fire lane. This is a “deluxe” installation and is most often seen at midblock crosswalks on busy urban streets. The first photograph shows a solar-powered, lighted sign and crosswalk. The […]

Accessibility: Don’t Create a Skate Park

Contractors leveling accessible parking stalls often use Portland cement concrete because the pavement elevations can be more precisely set with forms instead of using a paver placing hot mix asphalt concrete.  With either material, the slope from the accessible stalls must be gradually tapered to the existing pavement, otherwise a […]

Accessibility: Curb Ramps

A national retailer has a distinctive entranceway with three large planters. Curb ramps are constructed between the planters and tiles pave the plaza area to the doors. It is a nice, secure design which eliminates the need for bollards. The problem we find is the curb ramps typically have running […]
