Getting Through the Door- Solving DHI Complex Barriers to Accessibility

DHI Complex Barriers - ADA compliance. Rubber Threshold ramps for wheelchair access.

Title III of the Americans with Disability Act (ADA) requires 

all public accommodations to provide their goods and services to people with disabilities on an equal basis with the rest of the general public. Public accommodations include most businesses and services we all use each and every year…DHI complex barriers exist that we must deal with and fix.
                 There are over 56 million people with disabilities in the United States-one out of every five Americans. This number keeps growing as our population ages. The number of adults age 65 and over is projected to double by the year 2030. People with disabilities have $175 billion dollars in discretionary spending power!

Removal of DHI Complex Barriers

DHI Complex Barriers
DHI Complex Barriers exist that we must fix.

Title III of the Americans with Disability Act (ADA) requires all public accommodations to provide their goods and services to people with disabilities on an equal basis with the rest of the general public. Public accommodations include most businesses and services we all use each and every year. These include restaurants, hotels, theaters, convention centers, retail stores, shopping centers, dry cleaners, laundromats, pharmacies, doctors’ offices, hospitals, museums, libraries, parks, zoos, amusement parks, private schools, day care centers, health spas, bowling alleys, etc.

The goal is to afford every individual the opportunity to benefit from our country’s businesses and services, and to afford our businesses and services the opportunity to benefit from the patronage of all Americans. According to the U.S. Census Bureau, nearly one-half of all people over the age of 65 have a disability. There are over 56 million people with disabilities in the United States—one out of every five Americans. This number keeps growing as our population ages.

The number of adults age 65 and over is projected to double by the year 2030. People with disabilities have $175 billion dollars in discretionary spending power! Removal of Barriers To assist owners and facility managers in complying with the ADA for existing facilities, there are a set principals or priorities established in 28 CFR Part 36, Section 36.304(c) (1) (Removal of Barriers) of the ADA.

The first of these is to make improvements to your facility that provide the greatest degree of access for most people to your products and services. Following this concept is helpful in prioritizing and providing a starting point for barrier removal.

This includes making entryways barrier-free; that is, to modify (as necessary) to provide access to entryways on the path of travel from the parking lot into facilities and rooms where your products and services are provided. This significantly affects the door hardware industry in several ways. Our industry is called upon to provide the necessary products and solutions which solve complex barriers to accessibility in the most cost-effective manner.

Facility owners and managers are faced with the dilemma of having to modify buildings, sometimes of antiquated architectural design, under the sometimes conflicting, or at least confusing, statutory language of the ADA. Local and state building codes, some of which are in concert with the ADA and some of which are not, must also be considered when deciding the most appropriate ways to remove barriers.

Fortunately, with the adoption of the 2010 ADA Standards for Accessible Design (2010 ADAS) which became effective throughout the United States in March 2012, there were many improvements and corrections. This was the first major update to the 1990 ADA Standards, and many states are following suit. The ADA distinguishes between the standards of compliance for new construction, additions and simple barrier removal for existing facilities.

New construction must incorporate accessibility by design, construction methods and products used. Unfortunately, mistakes are made, and retrofit accessibility products can sometimes provide solutions. Altered facilities must also comply with new construction standards to the maximum extent feasible, and retrofit products are frequently used. All newly constructed or altered areas of facilities, either commercial or public, must be made accessible.

When the alteration goes beyond simple barrier removal and involves remodeling or renovation, different rules for barrier removal apply. Depending upon the extent of the alteration and the functional area modified and the usability of that area, different standards or burdens, to the extent of accessibility modifications required, may be placed on the building’s owner. For existing facilities, the ADA “requires the removal of architectural barriers…that are structural in nature…where such removal is readily achievable, i.e., easily accomplishable and able to be carried out without much difficulty or expense.” Door Thresholds

This brings us to one of the more difficult problems presented by existing buildings: door thresholds that are too high to comply with the 2010 ADA standards. Everyone agrees that threshold height can be a significant barrier to someone in a wheelchair or with another form of disability but removing that barrier can be difficult when also considering the construction of an ADA level landing or using a ramp with a 1:12 slope.

Very simply, it is desirable for a person in a wheelchair to be on a level surface when opening a door to be able to manage a wheelchair on a slope that is not too steep. Fortunately, the height of most thresholds that are out of compliance allow for modular level landing systems which can maintain existing slope and allow a person in a wheelchair to approach and open a door on a level maneuverable surface area. In these instances, it’s important to specify the side approach to these landings and be mindful that the cross slope be no greater than two percent. Interpreting the 2010 ADA while considering local building codes is not always easy and often demands interpretation, especially when you are trying to determine the best alternative to a difficult situation.

Therefore, best practices suggest that if your building was constructed before 1991 and a threshold is out of compliance, and is 3/4” or less in height, and there is no other modernization or construction going on, then a modest threshold ramp would act as a ”readily achievable” accommodation. However, in every other instance, a level landing at the door threshold would be required for threshold modification.

Clearly, the major impact of the ADA is on existing facilities. As stated in 2010 ADAS Section 202.3.1 Prohibited Reduction in Access: An alteration that decreases or has the effect of decreasing the accessibility of a building or facility below the requirements for new construction at the time of the alteration is prohibited. Although the ADA encourages “readily achievable” solutions to existing problems, once alterations for barrier removal has been initiated, all work must comply with the 2010 ADAS as for new construction and cannot be a reduction of access.

This was not as clear under the 1991 ADAS. 2010 ADAS Section 404.2.5 requires all thresholds at doors to be a ½” high maximum. Thresholds between a ¼” and a ½” shall be beveled with a slope not steeper than 1:2. Thresholds that do not exceed a ¼” high maximum may be vertical. Existing or altered thresholds ¾” high maximum that have a beveled edge on each threshold side with a slope not steeper than 1:2 are not required to comply.

The ADA distinguishes between the standards of compliance for new construc tion, additions A facility owner or tenant is often faced with the problem of having many door thresholds of ¾” or greater which do not meet with the 2010 ADAS requirements. Gene McFarren, an architect in Chico, Calif., points out that, “In the past, because of problems with water and moisture penetrating framing, many commercial building doorways were constructed with rises in thresholds to prevent water damage.

On-grade concrete floor slab systems in the 1967 Uniform Building Code required exterior lath extensions to extend below the floor line, which was before the advent of high-grade sealants.” Thus, past building requirements and construction practices may now conflict with present the 2010 ADAS for existing facilities. Facility owners throughout the country have thousands of thresholds demanding modification, involving substantial retrofit modification and expense.

Deciding to ramp or construct a level-landing at existing thresholds can become confusing when considering Section 404.2.4.1, Maneuvering Clearances at Manual Swinging Doors and Gates, which requires that there be a level landing area for hinge side and latch side swing door approaches. Essentially, landing areas in front of door thresholds must be level, a requirement which seems to conflict with desirability of using modular ramping systems as a practical solution to an access problem. These can appear at the interior of a door as with a new wooden sport floor system installed

The readily achievable standard, however, encourages some reasonable solution to the problem for the benefit of the disabled person and the facility owner. Ken Manrubia, a commercial door and hardware specialist of DLR Sales in California, states,

“The choice for customers is to either build up the concrete around the building or put in a modular ramp system. If one is using a ramp system, he should consider not only product cost but also installation method and cost.”

Modifications can be made using expensive traditional methods of saw cutting and reforming cement or by using less costly alternative level-landing products with transitions on front and side approaches. Concrete, pre-fabricated aluminum, and rubber matting landing systems are the usual options, aluminum and concrete being the most expensive to purchase and install. The rubber level landing and ramping system also have the advantage of being easily cut to fit in the field and can be attached with adhesives or other fastening device.

The door and hardware industry will increasingly be called upon to provide accessibility products and solutions to large and small businesses and public entities. With the growing Baby Boomer generation reaching retirement age, this will continue to demand full inclusion in the social and economic fabric of our country, and it behooves providers of products and builders to familiarize themselves as much as possible with the ADA requirements.

Most importantly, design officials, code enforcement officials, contractors, product suppliers and the disabled community must continue the dialogue to determine affordable and acceptable products for compliance purposes.
