Detail Drawings
All Standard Detail Drawings presented herein are intended to assist architects, engineers, other design professionals, contractors and UT staff in understanding the preferences of The University of Texas at Austin in the development, maintenance, construction and repair of its facilities. These Detail Drawings are intended to be used as guidelines. Detail Drawing documents require modification to meet the conditions and appurtenances of each project; therefore the legal responsibility for project document preparation shall continue to reside with the Design Professional. Refer to the Welcome Page for additional requirements. The Detail Drawings were created in AutoCAD 2007 file format; AutoCAD is a registered trademark of Autodesk Inc.
Important: These Detail Drawing documents are for use by The University of Texas at Austin and its consultants and contractors. Drawings remain the property of The University of Texas at Austin at all times.
Viewing Note: The CAD (DWG) files will not open in a browser, you have to save them to the your desktop.
