Handling pipe on construction jobs is a labor intensive, time-consuming and potentially-dangerous task, but one that is necessary on every water, sanitary sewer and energy pipeline project, as well as many utility projects where cable is placed in duct or conduit.

Roughly 280 delegates braved the weather and travel to attend the 56th annual meeting held at the Sheraton in St. John’s Newfoundland.

The Waterfront Mall Project under construction in Washington, DC, will contain retail stores, restaurants, offices and residential units. Through the middle of the site there is an existing 100-year-old, 90-inch diameter storm sewer about 800 feet long. In what should have been a relatively simple project to rehabilitate the pipe, with a few significant yet manageable challenges, circumstances quickly changed to create the “job from hell.”

The second annual Tulsa Pipeline Expo will be held Sept. 1 – 3, at the historic QT Center, formerly known as the International Petroleum Expo building at the Tulsa, OK, fairgrounds. The Tulsa Pipeline Expo (TPE) was created in 2009 and designed to showcase the thriving industries of energy and infrastructure in the Tulsa area, said TPE President Shawn Lowman.

Drive past most any construction site, and there’s a good chance many of the machines working there are rented, clearly marked by decals of the rental company that owns them. Most construction specialty niches rent equipment, including utility providers and contractors engaged in underground utility construction.

Most sewer infiltration enters structurally sound sewer systems through joints, manholes, service connections and the first few feet of the service lateral. This infiltration adds to treatment costs and increases the risk of sanitary sewer overflows (SSOs). A proven and economical way to permanently stop these leaks is with chemical grout.

For the 15th year, the Center for Innovative Grouting Materials and Technology (CIGMAT) and the Department of Civil and Environmental Engineering hosted a one-day conference on "Construction, Geotechnical, Hurricane and Flooding Issues in Houston & Other Major Cities" at the University of Houston on April 23. More than 280 attendees consisting of owners, consulting engineers, material suppliers, contractors and academia attended and participated from across the U.S.

In the spring of 2008, a reliability engineer at a major oil refinery contacted Inspar Robotic Technologies Inc., regarding concerns about the continual microbial corrosion problems they were encountering. The facility was experiencing multiple perforations in a progressive sequence from the effluent source in their hydrocarbon pipelines.
