Providing Surveying and Mapping to Support Utility Providers
Mark Thomas provides survey and mapping services to utility companies, ranging from small, local entities to large regional providers. We have delivered various type of projects included working in and around substations, construction staking for electrical transmission and distribution lines, system hardening and undergrounding (more than 300 miles), monument preservation, base mapping for gas pipeline projects, plan and profile for reconductor projects and dozens of other smaller projects. We also work with legal departments to address encroachment issues within easements. These efforts included locating trees, buildings and any other physical feature that would impede the safety of the services that are being provided and prepare an exhibit of the encroachment. Mark Thomas has also assisted in processing dozens of Caltrans Encroachment permits as well as processing permits for irrigation districts and railroad crossings.

Utility Locating
Subsurface Utility Engineering (SUE)
Mark Thomas offers Subsurface Utility Engineering (SUE) services to detect underground utilities for planning, project development, and design purposes, in accordance with industry-standard ASCE 38-22 guidelines. SUE provides essential information to mitigate costly delays caused by unexpected conflicts with existing underground facilities. Early detection of underground facilities benefits utility owners and clients alike, significantly enhancing safety during construction activities.
Our SUE crews employ record utility mapping in conjunction with electromagnetic (EM) locators and ground-penetrating radar (GPR) to detect and mark underground lines on the surface with paint, nails, and/or flagging. These markings can be collected by survey field crews either concurrently with SUE operations or at a later time, ensuring enhanced coordination and providing comprehensive information to the design team.
