Featured Projects
GRL Performs Various Q/A Tests on the Harbor River Bridge
Proposed in 2014, the Harbor Bridge replacement project has begun construction with quality assurance testing. The known vacation destination, Harbor Island, is accessed through this drawbridge, located on US-21 in South Carolina. This sea island was originally hunting land that had little need for incoming and outgoing traffic, which was sufficient for the bridge’s original capacity. Read More
New Jersey Hurricane and Storm Damage Reduction Project
Hurricane Sandy hit the coastline of New Jersey at the end of October 2012, causing millions of dollars in damages including 750 homes impacted by the storm in Port Monmouth township, New Jersey. Read More
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
