As a contractor does your project manager emphasizes on the importance of installing code-compliant tactile solutions in the project? Are you aware of the standard requirements of tactile solutions? If the answer is no, you are not alone. Contractors often come under the wrath of the project manager as they are unable to meet the standard requirements. The reason being, although they know the importance of installing tactile solutions, they are clueless regarding the code standards. To safeguard the interest of contractors and ensure tactile solutions are installed according to standard requirements, we have created this guide, “Your Source for Code Compliant Tactile Solutions.” This go-to guide will give contractors a complete understanding of what code standards are and how to incorporate them in the project.
Before starting the project, contractors must know which tactile solution is best suited for the inside and outside. Contractors must also know which tactile solution is suitable for wet concrete and which one to glue to the existent surface. From color standards to design layout and size requirements, contractors need to keep all these things into account before installing the tactile solutions.
Need for installing code-compliant tactile walking surface indicators
According to the accessibility legislation, contractors need to install tactile walking surface indicators (TSWI) for the assistance of visually impaired people. Contractors have to install TWSI at dangerous pathways or drop-offs for warning visually impaired about the hazards in their path of travel. Before installing the TWSI, contractors have to ensure four things.
- The tactile solutions are code-compliant
- TSWI is available in standard size
- TWSI is color compliant
- And last but not least they should be visually appealing as well.
Must follow the design basics
Before starting the project, contractors must address four fundamental elements to meet the needs of people with vision loss:
- Size requirements
- Color contrast
- Standard material
Must be color compliant
The first thing contractors need to address is whether tactile waking indicators need to have color contrast. Tactile indicators serve the purpose of warning the visually impaired about the hazards. And for doing so, contractors need to ensure that the tactile solutions have a code-compliant luminance contrast with the surrounding surface. Talking about the visual contrast, it has three dimensions.
- Brightness: It is the amount of light reflected by a surface. Contractors must understand that the difference in brightness provides the main contrast available to people with poor color discrimination. For measuring brightness, contractors can make use of a luminance meter.
- Hue: It is the basic color reflected by the surface and is defined by elementary colors like red, green, yellow, and blue. Also, if the aesthetics of the design indicates that the TWSI must have a similar hue as the adjacent surface; then the contractor must ensure that the TWSI has an increased contrast. To achieve this, contractors need to have a more significant difference between brightness and saturation.
- Saturation: It is the purity of color. Colors with high saturation are pure and vivid. Safety yellow is recommended as the standard color due to its clear contrast with most of the surrounding surfaces.
Layout for the TWSI
Contractors must follow a consistent, logical, and straight forward design for both exterior and interior environments. Contractors have to ensure that the path of travel is safe, accessible, and has distinct tactile qualities in a place where pedestrian traffic crosses through large open areas. Contractors must use straight lines and consistent right angels in their layout.
Material to be used for the TWSI
“Your Source for Code Compliant Tactile Solutions” will help contractors in determining which material is best suited for the tactile walking surface indicators. There are a variety of materials contractors can choose from like concrete, steel, and rubber. Now which one to go for will depend on the code standards, environmental conditions, and the ability of the TWSI to withstand the harsh vehicular environment. Also, contractors must ensure that the tactile walking surface indicators are durably UV-stable and are corrosion-resistant. The most commonly used TWSI, are stainless steel and cast iron and polymer.
Installation guidelines for installing TWSI
Here are some tips that will help contractors in installing TWSI as per the code standards.
- Proper monitoring during the design phase: One reason for the failure of the project is the lack of adequate planning by the contractors. Planning and strict monitoring during the design and installation phase will ensure the smooth construction of the place where contractors have to install the TWSI. Contractors have to maintain a specific distance from the hazardous region where they have to install the TWSI.
- Proper placement: Contractors must ensure that the placement of tactile tiles must be precise to prevent deviations from standards. Contractors have to assure that the placement is carefully measured and monitored to avoid any uneventful situation.
- Make the place accessible for proper installation: The layout matters to ensure compliance with the code standards. While installing the tactile indicators like attention domes, contractors have to ensure they are high raised to a limit. They should not exceed any point beyond the normal flooring level.
- Take environmental conditions into account: External conditions play a vital role in the installation of code-compliant TWSI. Weather conditions will impact the performance of the tactile indicators. Hence, contractors have to ensure that the TWSI is weather and wear-resistant. To withstand harsh weather conditions, tactile indicators must have the rough required surface for a better grip. To avoid installation errors, contractors must always use high-grade materials and follow proper instructions. Other things contractors have to take into account during the installation of tactile walking surface indicators include UV exposure, foot traffic, and extreme weather conditions.
As we come to an end of this guide on “Your Source for Code Compliant Tactile Solutions,” contractors will now have a complete understanding of code-compliant tactile solutions. Contractors must follow the above guidelines to translate their project into a success.
