Interactive Pipe Inspection (IPI) is building an impressive record of complex inspections of pipe submerged under water. Last year, Underground Construction magazine reported on projects for King County, WA, in which IPI inspected more than 50,000 feet of sanitary sewer lines beneath two lakes.

The question invariably is asked after severe weather or other disasters knocks out electrical power and communications services: “Why don’t they put those overhead lines underground where they’re protected?”
That question has been asked many times in many places over the past few years as heavy winter storms, tornadoes and hurricanes have affected much of the country, knocking out power, communications and other vital services.

When USD 233 – more commonly known as the Olathe, KS, Public School District – was formed in 1965 by consolidating five smaller districts, enrollment totaled 3,687 students. Since then, it has grown every year and is now the second largest of all the school districts in Kansas. The 2013 school year began with more than 29,000 students attending classes at the four high schools, nine middle schools and 35 elementary school buildings that compose the district.

Reacting to the changing needs of the evolving horizontal directional drilling industry, UCT has launched an educational program and interactive display at this year’s event.

Established in 2004 by a small group of directional drilling contractors as a regional association, the Northeast Trenchless Association (NTA) has not only served the underground industry in New England – an area not known for conditions conducive to directional drilling – but has established a strong national presence, as well. The group has expanded to encompass all methods of trenchless construction and rehabilitation.

The power supply for Virginia's densely populated Middle Peninsula Area, on the Chesapeake Bay, is currently adequate but somewhat fragile; a single 115 kV line extends southward from the Harmony Village Substation of Dominion Virginia Power (DVP). The non-redundant power supply was at risk for long interruptions and local demand threatened to outstrip supply.

Underground Construction and Pipeline & Gas Journal’s pipeline construction survey indicates that 77,318 miles of pipelines around the world are in various stages of construction and planned. Of these, 33,205 represent projects in the planning and engineering phase and 44,113 are in various stages of construction.

Underground Construction’s 2013 census of large horizontal directional drilling contractors is an effective tool when selecting the right size of drill rig to fit specific project needs in managing a successful HDD operation.

From design and planning through securing-right-of-way, permitting, logistics of getting equipment and material in place and actual construction, utility projects can be complex and challenging. Often environmental issues and public concerns further complicate the job.

There was a time when engineers designed structures to last for eternity. Since the beginning of mankind, civilizations have desired to create an enduring legacy through their architecture. Engineers from ancient civilizations such as Egypt, Greece and Rome did not build their fabulous structures and monuments with the intention of having them repaired every 50 years.
