Chapter 9: Construction and Maintenance Guidelines

Anchor: #i1000073

Section 1: Overview

Introduction

This chapter addresses issues of concern to construction and maintenance personnel. Design personnel can also benefit from the information provided here.

Anchor: #i1000107

Consistency

Consistency in the areas of illumination, electrical plans, project electrical inspection, and electrical maintenance is important. Districts can better achieve consistency if one office has specific control of all illumination and electrical plans and one or more inspectors specialize in illumination and electrical projects.

Anchor: #i1000126

Assistance

The TxDOT Traffic Operations Division (TRF) is available to help with design, construction, maintenance, and questions upon request. Districts should feel free to take advantage of their illumination and electrical systems expertise.
