Texas Accessibility Standards
As of March 15, 2012, the 2102 Texas Accessibility Standards (TAS), will be enforced in TX. This document contains scoping and technical requirements for accessibility to sites, facilities, buildings, and elements by individuals with disabilities. The requirements are to be applied during the design, construction, additions to, and alteration of sites, facilities, buildings, and elements to the extent required by regulations issued by the Texas Department of Licensing and Regulation under the authority of Texas Government Code, Chapter 469. These standards are intended to be consistent to those contained in the 2010 Standards of Accessible Design.
Registered Accessibility Specialist
A Registered Accessibility Specialist is a professional licensed with a state of the United States to determine if a part of the built environment (building, park, sidewalk, parking lot) is compliant with Americans with Disabilities Act and state laws. A RAS reviews construction documents to determine the accessible design and inspects finished buildings to verify accessible construction.
Currently, Texas contains the most stringent accessibility laws. The Texas Accessibility Standards go above and beyond (in some cases) the expectations of the ADA. The TDLR (Texas Dept. of Licensing and Regulation), for example, requires that all commercial construction projects over US$50,000 submit to a RAS for verification of compliance.

Façade is the main face of a building.
Felt is another word for the tar paper placed under roof shingles.
Fire Block is a 2” x 4” horizontal wood member nailed between wall studs used for fire and smoke suppression. They are also referred to as fire stops.Fire Wall is a wall specially designed to slow down the spread of fire in a building. All door openings in firewalls must have fire doors installed in them.
Fire Wall is a wall specially designed to slow down the spread of fire in a building. All door openings in firewalls must have fire doors installed in them.
Flashing is sheet metal used in roof and wall construction to prevent water intrusion.
The flue is the opening in a chimney through which gas and smoke pass to outside the building.
The footing is a foot-shaped projection at the base of a foundation wall used to prevent shifting or settling.
Fuse is a device that prevents the overloading of an electrical circuit by containing a strip of metal which will melt at low heat and thereby break the circuit.
Geology is the science and study of the earth, including the processes that change it. Geologists study rocks and geologic features.
Geotechnical Engineering is concerned with soils, foundations, slopes, retaining walls, groundwater, and related areas. Geotechnical engineers are civil engineers. Geotechnical engineers also assess the risk to people and property from natural hazards such as landslides, sinkholes, earthquakes, and soil liquefaction.
GFCI or Ground Fault Circuit Interrupter is a plug designed to shut off the current when a dangerous condition exists. A GFI protects people while fuses and circuit breakers protect equipment.
The grade is the ground level or elevation. It also refers to the process of leveling soil or the quality of manufactured wood.
