A Primer to Cathodic Protection for Underground Piping Utilities

Posted by Edward Dill on Jul 13, 2018 9:00:00 AM


An Overview of Cathodic Protection

Cathodic protection is the process in which American Society of Mechanical Engineers (ASME) underground piping and propane tanks are protected from aggressive rust. (That is to say, some rusting is not necessarily harmful.) Cathodic protection addresses the steel disease (oxidation) by providing a protective layer to prevent further rusting. There exist two means in which cathodic protection for metal is achieved for underground piping: galvanized anodes (often referred to as sacrificial anodes) and impressed currents (typically referred to as impressed current cathodic protection).

What the Federal Infrastructure Plan Means for Bridge Utilities

Posted by Edward Dill on Jun 25, 2018 9:02:00 AM


The federal government is making a huge investment in infrastructure. Under the new plan announced in early 2018, over $1.5 trillion in infrastructure spending will be spurred by investments at the federal, state, and local levels.

What are some of the standout features of the plan itself, and how will they impact the future of bridge utility work?

4 Slowdowns to Anticipate During a New Bridge

Posted by Edward Dill on Jun 18, 2018 9:02:00 AM



There are a lot of potential hurdles to a successful bridge building project. As bridge utilities experts, Aptus has seen more than our share of projects stalled, halted, and otherwise interrupted by unexpected red tape.

When you’re managing a major bridge construction project, particularly repairing or installing bridge-attached utilities, here are a few common causes of slowdowns to anticipate.

Bridge Features that Help Optimize Bridge Utilities

Posted by Edward Dill on Jun 11, 2018 9:01:00 AM


The success of a bridge utilities project is largely dependent on the bridge itself. There are a wide variety of factors that contribute to the simplicity and/or complexity of an install, and even more that contribute to the process of repair and/or updating.

Aptus has worked on thousands of bridges all across the United States. We understand what makes a utilities project work – and what can slow one down. Here are a few features that almost always mean a bridge project will remain as uncomplicated as possible.

What Makes a Bridge Utilities Installation Challenging?

Posted by Edward Dill on Jun 4, 2018 9:02:00 AM


Aptus is the leader in bridge-attached utilities for a reason. We’ve spent decades developing the skills and experience necessary to tackle some of the most complicated installations and repairs in the industry. We’ve never met a bridge we couldn’t handle.

That being said, some bridge utilities projects are far more challenging than others.

Which factors ultimately complicate the installation of utilities on bridges?

3 Ways Bridges Improve Cities Beyond Transportation

Posted by Edward Dill on May 30, 2018 9:03:00 AM


Bridges are breathing new life into cities.

In the United States alone there are over 600,000 bridges standing today. Hundreds more are being constructed every year.

How are bridges improving cities beyond the obvious? What impact do these structural marvels have on cities beyond their ability to move people from one place to another?

Installing Utilities Piping in Tunnels: 4 Things to Consider

Posted by Edward Dill on May 21, 2018 9:02:00 AM


For bridge piping experts, tunnels present a unique set of challenges. The working conditions inside tunnels can be quite cramped, and many tunnels in the U.S. are ageing in place rapidly along with their existing utilities.

It’s not uncommon for tunnels’ utility piping to be completely replaced after decades of use, or for utilities to just now be installed inside tunnels for the first time. As advanced telecommunications become more widespread, some tunnels now act as support structures for important utilities such as carbon fiber cabling.

When installing utilities piping in tunnels, which considerations are the most important?

4 Factors That Determine Utilities Design for a New Bridge Build

Posted by Edward Dill on May 14, 2018 9:01:00 AM


New bridge builds are always complex. Between materials procurement, resource management, and the inevitable public inconvenience, there are a lot of components involved in building a new bridge whether it’s a 20-foot pedestrian span or a half-mile-long vehicular overpass.

How does utilities design factor into the process? At Aptus, we have years of experience designing bridge piping for utilities like water, sewer, and telecommunications cabling. Here are what we’ve learned are the four factors that ultimately steer the direction of design.

3 Recent Developments in Bridge Building

Posted by Edward Dill on Apr 26, 2018 9:04:00 AM


Bridges are some of the most complex pieces of infrastructure on the planet. From suspension spans to flat-pack elevations, technological advancements have changed the scope of bridge construction drastically over the past several decades.

Aptus keeps our fingers on the pulse of bridgework because innovations in the bridge space are inherently related to what we do best. Our bridge-attached utility projects ultimately function as an extension of the bridges they’re supported by.

Here are three exciting developments in the bridge building industry we’re keeping a close eye on.

Bridge Utilities Piping for Drawbridges 101

Posted by Edward Dill on Apr 18, 2018 9:08:00 AM


Drawbridges are special.

There are hundreds of drawbridges in the United States spanning canals, rivers, bays, and other bodies of water. Many are fifty years old or older. As these bridges age, cities must make difficult choices about whether to invest in the significant repair work required to keep them operational. Chicago, for example, one of the drawbridge capitals of the world, has over 60 drawbridges, only 43 of which remain operational today.
