Featured Projects
Bridge Replacement in Growing Cairo, West Virginia
The small town in Cairo, West Virginia began growing in truck traffic when the oil and gas industry started taking roots in the city. Off of a major highway, the original bridge connected route 31 over the North Fork Hughes River. Burgess and Niple reached out to GRL Engineers to bring them on the project for testing. Read More
SR-19 Over Little Lake Harris Bridge
The current bridge over Little Lake Harris in Central Florida has been in use since 1950. The original bridge that connected Howey and Astatula was a long, wooden bridge that opened in 1927. After the second span was built, the wooden bridge was torn down, only leaving a small dock in its place. Being the third iteration of the pathway from Howey and Astatula, it is of significance that the new bridge can service the drivers of Lake County, Florida. Read More
Russell Street Bridge Replacement
The existing 2-lane Russell Street Bridge in Missoula, Montana, a major highway with high traffic volume, was in need of reconstruction. GRL was contacted to perform a bi-directional static load test (“BDSLT”) on a representative test shaft. The test shaft had a diameter of 71 inches, and a length of 75 feet. The embedded bi-directional jack assembly contained three 2,200-kip GRL-Cells, resulting in a potential test load of 13,200 kips. GRL provided thermal integrity profiling (“TIP”) services to assess concrete quality and post-concreted geometry of the test shaft. Read More
Norfolk Southern Rail Road Over the Grand River
The Norfolk Southern Railroad Bridge over the Grand River in Painesville, OH, was built in 1905 and reinforced in the 1940’s. High maintenance costs and a restrictively large footprint in the Grand River led to the decision to replace the bridge. The Great Lakes Construction Company was awarded the contract and chose Suburban Maintenance Construction, Inc. to install 26 drilled shaft foundations ranging from 4’ to 7’ diameter and up to 93.5 feet in length. GRL Engineers, Inc. provided the SQUID equipment, data evaluation and reporting. Read More
The New Tappan Zee Bridge
GRL’s services for Tappan Zee Constructors included completing a multitude of Wave Equation Analyses for hammer selection, Dynamic Pile Testing (PDA) on temporary and permanent 36 to 48-inch diameter open end pipe piles, performing Crosshole Sonic Logging (CSL) and Thermal Integrity Profiling (TIP) on 48 to 96-inch diameter drilled shafts. GRL also provided expert services on data interpretation and reviewing project specifications. Additionally, GRL Engineers provided driving criteria based on the Wave Equation Analyses, dynamic testing results and field observations. Read More
Corpus Christi Liquefaction LNG
Corpus Christi Liquefaction, LLC, a subsidiary of Cheniere Energy, is developing and constructing a liquefied natural gas (LNG) export terminal at one of Cheniere's existing sites that was previously permitted for a regasification terminal.
PDA Testing, SiteLink® Remote Testing, Crosshole Sonic Logging, Thermal Integrity Profiling and Pile Integrity Testing on Drilled Shafts was per formed. Read More
Port of Tacoma Pier 4
The Port of Tacoma has numerous Piers for the loading and unloading of ships carrying containers. GRL Engineers also performed dynamic pile monitoring on selected piles, during initial driving, and again during restrikes.
Preliminary GRLWEAP Analysis, Dynamic Pile Monitoring and CAPWAP Analysis were performed. Read More
Bonner Bridge
Since the Bonner Bridge was constructed in 1965, numerous hurricanes have struck the Atlantic coast wreaking havoc on the Outer Banks of North Carolina. GRL Engineers were called in to help aid in the replacement of this nearly three-mile long bridge across the Oregon Inlet from Bodie Island to Hatteras Island.
Static Load Testing and PDA Testing Services were performed. Read More
