Wind Farms From A Utility Perspective

When you think of wind farms, you often think of the large structures stretching into the sky, but what about what lies below? An extraordinary amount of planning and thought goes into the design and construction of each wind farm. Preplanning for these projects often happens more than a year in advance before any ground is broken for the construction. Several factors need to be considered for each project, such as the wind farm’s location, the number of turbines being installed, and even the location of the underground utilities and infrastructure.

Why You Should Scan Before You Cut or Core Concrete

Performing work on existing concrete is often a necessary part of construction. Coring, drilling and cutting are just a few of the techniques which are used on concrete slabs and walls. This concrete can contain rebar, conduit, post tension cables and other materials, with the potential to cause major damage if hit.

What is GPR?

GPR (Ground Penetrating Radar) is a general term for a collection of devices used to locate objects within materials, typically in applications where visual inspection is impractical. GPR is often used to locate underground objects, but it’s also used on manmade structures. Its basic operation is to emit and receive the signals that reflect off of subsurface objects. GPRS uses GPR to scan concrete for objects such as rebar, or to locate utilities.

Top 5 Reasons To Get A Routine Water Loss Inspection

If you manage a municipality or an extensive water system, you know that losing water is an inevitability. Parts of our current water infrastructure in the United States can be upwards of 100 years old. With these old and aging pipes, there will be breaks, cracks, and leaks. Before we get into why it’s essential to get a routine water loss inspection, let’s talk about some of the science on how leaks are detected.

Locating Sewer Lines

Sewer lines are a key utility but are often overlooked by public and even private utility locating services. Lines can be made of a variety of materials, depending on their age and location. The majority of sewer piping material is non-conductive- materials such as HDPE, PVC and even clay are all commonly used. Lines can be decades old, meaning that accurate plans and as-builts are often missing or non-existent.
