Project Name: Grosse Ile Municipal Airport Runway 4-22 Reconstruction and Lighting Rehabilitation
Manufacturer: Brutsche Concrete Products
Installer: Dan's Excavating
Project Location: Grosse Ile Township, MI
Year Built: 2016
In 2015, Grosse Ile Municipal Airport in Grosse Ile, Michigan, decided that Runway 4-22 was ready for an upgrade. The proposed reconstruction project included brand new asphalt as well as 145 new runway lights.
Each of the new runway lights required a concrete foundation that needed to extend 40 inches below grade to be below the frost line in the cold winter months.
To build similar foundations, contractors traditionally use a cardboard forming system that would often prove wildly time consuming. This method requires the on-site team to build the foundations by hand, utilizing a mechanism to hold everything in place while waiting on a cement truck. At that point, they would need to wait even longer while the concrete cured enough to mount a light fixture.With 145 new lights, building each foundation on site by hand would be a daunting task for even the most experienced contractor.
Dan’s Excavating was awarded the project in late 2015 and decided to look for alternative solutions that would expedite the foundations for the new runway lights.
For each new light fixture, the foundation housing the L-867 lighting can had to be 42 inches tall with a 24-inch diameter, and needed two segments of 2-inch conduit. After careful consideration, Pole Base—a precast concrete foundation system specializing in lighting foundations—was ultimately selected to provide these foundations.
Manufactured and cured in a controlled setting before being shipped directly to the site, the precast foundations would allow Dan’s excavating to save time on labor by eliminating the need to build the cardboard form themselves and wait for the concrete to cure.
As the bases were completed and began arriving on site, the team from Dan’s Excavating was able to store them in a staging area until they were needed to begin installation. The installation process was straightforward. All the installers had to do was dig the hole, lay some crushed stone at the base of that hole, and set the unit in place utilizing Pole Base’s unique lifting device that hooked to the inside of the light can. Once the base was set, and after running the necessary wire and backfilling, the team was ready to move onto the next base.
“This product gave us the flexibility to install on our own schedule, which makes us much more efficient and in turn, more competitive,” said Randy McTaggart of Dan’s Excavating. “The product also installed quickly and was easier to work with than traditional methods.”
In the end, Dan’s Excavating was able to install the foundations lining the runway and complete the lighting portion of the project quickly and efficiently. “These bases were very easy to work with and it’s been very helpful to be able to install them without having to wait for a mixer to show up on site,” explained McTaggart.Want to learn more about Pole Base taxiway applications?
