Note: Baker-Peterson’s methods for utility locating are nondestructive and green.


Baker-Peterson specializes in identifying and locating underground utilities that are not covered by the 811 service; including Gas and Oil pipelines, Water, Communication, Electric, Waste Water, Fiber Optic, and others. Private utility locating involves a variety of techniques and equipment, which include Electromagnetic, Ground Penetrating Radar, and more. Baker-Peterson’s approach to utility locating is based on over 80 years of field experience and meets or exceeds NULCA Competency Standards, CAPULC Pipeline Locating Standards, and PHMSA requirements. Baker-Peterson utilizes technology and techniques in a multi-layered approach that offset each technologies’ limitations to ensure the best possible outcome when locating. Our specialized approach while conducting utility exploration combined with taking the time to communicate with all parties involved, ensures your team is protected and there aren’t any surprises.


Conventional Electromagnetic Locating utilizes equipment that detects electromagnetic fields applied to the targeted utility actively or passively. Methods of Electromagnetic Locating include Direct Connection, Coupling, Induction, Sweeping (Active and Passive). Electromagnetic Locating is the most accurate and reliable due to the locate frequency being directly applied to the targeted utility.


Ground Penetrating Radar, or GPR, is a locating technology that emits energy waves into the ground and measures the return to identify subsurface anomalies. Further investigation of the anomalies allows locators to determine the presence of possible buried utilities and their path. GPR is particularly useful for identifying the location of non-metallic lines, which do not respond to electromagnetic methods. GPR can be used to find underground tanks, and other disturbances in the earth.


Subsurface Utility Engineering (SUE) is a multi-phase process often used in the design stage of a major construction project. SUE involves physically locating utilities, identifying ownership of utilities, vacuum excavation to positively identify (location, depth, material, condition, and size of the utility), and mapping the GIS coordinates of the utilities. Engineers and contractors then design their project around the existing utility locations to avoid delays, saving time and money. SUE is an important component of the construction planning process to avoid safety risks and prevent design changes due to finding unknown utilities during the construction phase. It is estimated for every $1 spent on SUE, there is $5-$10 saved in prevented design changes and utility damage.


Baker-Peterson works with our clients to understand their specific project needs and design a SUE solution that best meets that need, and ensures compliance with ALTA/NSPS Land Title Survey Table A, Item 11 requirements.


SUE has several levels based on project needs.


Quality Level D (QL-D)-The most basic Utility information derived from existing records and/or oral recollections. Level D is highly limited in terms of accuracy and is useful during preliminary route selection.


Quality Level C (QL-C)-Utility information derived by surveying and plotting existing visible above ground utility features and using professional judgement to correlate this information with the information gained through Level D investigation. Level C is useful to determine the origin or termination point of utilities but does not represent the path taken by the utility once it leaves the visible structure.


Quality Level B (QL-B)-Utility location information obtained through the application of appropriate locating techniques. Commonly referred to as “designating”. The actual path of the utilities is physically located and marked in the field, then GIS location data is collected to include in design documentation. The resulting view of the existing utility infrastructure allows engineers to make design changes to avoid congestion and costly utility relocation.


Quality Level A (QL-A)-The most accurate Utility location information available. Level A utilizes the full range of SUE services. Along with identifying the location of utilities, ownership is determined based on information collected in the field and research conducted to identify the appropriate owner contacts. Identified utilities are non-destructively potholed or excavated to verify the exact utility type, size, condition, material, and depth of the line. Findings are documented and GIS data is collected for inclusion with design documentation. The resulting “full view” of existing utility infrastructure allows engineers to determine the true impact of existing infrastructure and determine if design changes are necessary to avoid congestion and costly utility relocation.


Once utility locating is completed, Baker-Peterson offers GIS mapping of the findings for documentation and future use as reference prints. Baker-Peterson utilizes the latest in GIS equipment providing an accurate depiction of utility placement. Along with the GIS utility coordinates, Baker-Peterson also collects utility documentation as requested by our client and data is delivered in the format requested. Data formats include: Shape Files, Arc GIS, CAD, PDF, and KMZ.


Baker-Peterson specializes in damage prevention consulting, consisting of effective use of one-call/811 Call Before You Dig service, pre-excavation documentation, efficient communication between all parties and audits of existing practices.


Unfortunately, utility damages do occur and it’s important to understand the best practices to follow during a utility damage investigation. At Baker-Peterson, we provide utility damage investigations training on what to do immediately following an incident, such as photo documentation and measurements needed, as well as how to prepare before an excavation to protect your company.


Baker-Peterson management, who bring a combined 80 years of experience in utility location, can serve as expert witnesses in utility damage cases where a knowledge of proper utility location procedures and safety precautions is necessitated. Our team has served as experts in more than 100 cases involving utility damage.


Baker-Peterson staff provide utility locating training to construction, utility and other workers. We focus on proper utility locating practices and emphasize attention to detail, quality and safety. Training includes electromagnetic theory, troubleshooting techniques, choosing the best tools, correct marking procedures and more.
