The Center for Innovative Grouting Materials and Technology (CIGMAT) Research Center was established in 1994 at the University of Houston, Houston TX. CIGMAT’s goals are to foster improved understanding of grouting and coating materials under various applications. Also of interest are other competing and complementary materials and technologies to grouting and coatings used in the construction and rehabilitation of civil infrastructure and offshore pipelines.
When horizontal directional drilling (HDD) professionals discuss the size of an HDD rig, they usually refer to the maximum pullback force the unit can develop. The most common industry standard for a large directional drilling unit is defined as having a minimum of 100,000 pounds of pullback force. In addition to pullback, the most common specifications used to categorize HDD equipment are rotary torque of drill stem, rotation speed and the size of drill pipe.
It had been more than 35 years since Junior Kool and wife Beverly opened the first Vermeer Midwest location in Eureka, IL, so expanding the dealership’s original facility -- built by Kool in 1976 -- was imminent.
The Center for Innovative Grouting Materials and Technology (CIGMAT) is currently working on projects related to composite coatings to protect reinforced concrete and repair methods for corroded steel piles. Over the years, CIGMAT researchers have developed unique testing facilities and developed test protocols approved by the U.S. Environmental Protection Agency to test grouts and coatings for infrastructure rehabilitation. A Life Cycle Cost model (CIGMAT-LCC) for wastewater systems has been developed and may be viewed on the CIGMAT website.
The 46th Annual International Pipeline and Offshore Contractors Association (IPLOCA) Convention convened recently in Istanbul, a dynamic city where East meets West and the past and present collide. The venue was perfectly suited as the 680 delegates from around the globe.
A recent project to install more than 6,200 feet of electrical transmission lines in Orange Beach, AL, included multiple challenges, including two intersecting horizontal directional drilling (HDD) pilot holes beneath Wolf Bay inter-coastal waterway channel to complete a single crossing.
Separate regulatory and legislative developments could affect local government ability to afford water infrastructure projects. The Environmental Protection Agency is considering revisions to the agency's 1997 financial capability guidelines which dictate how hard the agency can press cities and counties to undertake expensive Clean Water Act projects such as sewer repairs.
