What is subsurface utility mapping?

Subsurface Utility Mapping (SUM) is the new standard in underground work, directly impacting the success of a project by minimizing risk, improving project execution, and minimizing changes and claims.

What is Sue Level A?

The different levels of potential SUE investigations include: Level A: This is the most in-depth level of investigation. It requires physical digging to locate the exact spots of these utilities. Typically, professional engineering consultants use non-destructive methods.

What is Sue in construction?

Subsurface Utility Engineering
Many States utilize consultants to identify the quality of subsurface utility information needed for highway plans, and to acquire and manage that level of information during the development of highway projects. This engineering practice is known as Subsurface Utility Engineering (SUE).

What is a Sue technician?

SUE Technician II Subsurface Utility Engineering (SUE) is a branch of engineering that deals with mitigating risks associated with new infrastructure design and construction.

What does PAS 128 stand for?

underground utility detection, verification and location
What is PAS 128? British Standards Institution (BSI) PAS 128 is the current specification for underground utility detection, verification and location. The degree of confidence of each PAS 128 survey is clear, based on the category and level of survey carried out.

What is subsurface utility exploration?

Subsurface Utility Engineering (SUE) is a discipline of civil engineering that involves the investigation of buried utilities and identifies the conflicts they may pose to a project design in order to mitigate associated risks.

What is a Level B Sue?

Subsurface Utility Engineering Quality Level B: Utility Designation. Quality Level B. determines the existence and horizontal position of utilities through the application of appropriate surface geophysical methods.

What length should painted locate marks be?

30 cm to 90 cm
Practice Description: Facility locators match markings to the existing and expected surface conditions. Markings may include one or any combination of the following: paint, chalk, flags, stakes, brushes or offsets. Paint marks will be a length of 30 cm to 90 cm and approximately 3 cm wide.

What does utility engineer do?

Utilities Engineers perform mechanical, electrical, and civil engineering work in the design, construction, operation and maintenance of water systems, electrical power lines and power plants, telecommunications facilities, gas pipelines, and light and heavy rail systems.

What is a PAS survey?

What is PAS 128? British Standards Institution (BSI) PAS 128 is the current specification for underground utility detection, verification and location. The degree of confidence of each PAS 128 survey is clear, based on the category and level of survey carried out.

What is a utility survey?

What is a utility survey? A utility survey uses Ground Penetrating Radar (GPR) and Electro-Magnetic Locators (EML), to analyse reflected signals from structures, services, buried objects beneath the ground.

What is the APWA color code?

Red: Electric power lines, cables or conduit, and lighting cables. Yellow: Gas, oil, steam, petroleum, or gaseous materials. Orange: Communication, alarm or signal lines, cables or conduits, and fiber. Blue: Potable water.
