Underground Utility Maps


Underground utility mapping (also known simply as underground mapping) is the process of creating a map that represents the layout of utilities running below the surface. Creating an underground utility map starts by surveying and mapping the plan or design of the site.

This type of map is created with a computer-aided design (CAD) and mapping software. The data for this type of map can be gathered from observation and from information supplied by utility providers.

The next stage is to take measurements and apply them to represent the underground utilities in a manner that allows for easy identification of any potential conflicts and distortions on the surface.

According to their spacing and direction, utilities such as water, sewer, storm drains, natural gas lines, electrical transmission lines, etc. will be represented on the map.

We provide services for vast range of construction sites:

Power Substations and lines



Residential Developments

... and more


Engineers are often called upon to use computer-aided design (CAD) and mapping technology to plan, design, and construct a community’s infrastructure. The increasing complexity of construction projects has led to a significant expansion in CAD and mapping services beyond site layouts for roads, water systems, sewers, storm drains, and other utilities; now, more comprehensive solutions are available that include geotechnical investigations such as 3D modelling of subsurface conditions.

We work with architects & planners during the initial phases of development to create detailed drawings from our data to save time & money throughout the project lifecycle. Our staff members are trained in all aspects of surveying, including creating floor plans, utility locating, and other services used during phases of project preconstruction, such as topographical/site plan surveys. Our data capture is conducted by professionals experienced in construction surveying operations with many years of experience in the field.

In the past, these types of projects would have been difficult or impossible because they require manual surveying skills. However, there is less need for expensive equipment with laser scanning, and the results can be obtained and analysed more easily.

The main benefit of laser scanning is that it produces highly accurate 3D point cloud. This data can then be used to create a wide range of visualisations, which can be helpful for engineers and designers alike.

We are authorized to make projects on power substations, power lines and other types of buildings.
