Purpose of the TxDOT Survey Manual

This manual is intended to be a general reference for surveying procedures performed by and for the Texas Department of Transportation (TxDOT). This manual is not a step-by-step instruction manual or a surveying textbook. The purpose of its publication is to establish minimum standards, policies, and procedures of surveying for TxDOT. The manual incorporates appropriate reference material for surveying as well as the rules adopted by the Texas Board of Professional Land Surveyors (TBPLS).

Manual Creation

The members of the Standing Committee on Surveying (SCOS) created the TxDOT Survey Manual. SCOS members were appointed to ensure department-wide compliance with all applicable laws, to serve as a liaison between TxDOT and the TBPLS, and to develop a set of procedures to be followed by TxDOT employees, contractors, and consultants performing surveys for TxDOT. As part of the SCOS charter, its members have developed this current TxDOT Survey Manual to incorporate changes in technology and the evolution of surveying methodology and policies at TxDOT. This manual will be updated as necessary.
