Foundation Repair Case Studies: Restoration of Historic Building
Resistance piers were installed under the foundation for temporary shoring; pressure-grouted micropiles were then installed to complete our portion of the restoration.
Thrasher is installing temporary resistance piers so the foundation can be excavated and a new supplemental concrete footing can be poured.
The building, which was added to the National Register of Historic Places in 1974, was rejuvenated after being vacant for more than 40 years.
Thrasher was hired to assist in the renovation of the historic Burlington Railroad Station in downtown Omaha, Nebraska for KETV’s new broadcasting facility.
The Burlington Railroad's Omaha Station is located at 1001 10sth St. in downtown Omaha, Nebraska. This building was originally built in the late 1800s and was opened to the public on July 4th, 1898. The structure was designed by Thomas Kimball and was hailed by newspapers around the world for its grand architecture and accommodations.
The total cost for the station's construction was over $400,000 in 1898 currency, making it a very extravagant building.
The building went through an extensive remodel from 1929 to 1930 to compete with a newly constructed Union Station in Omaha. The facility operated in that condition until 1954, when it went through its second major renovation. The renovations in 1954 primarily consisted of parking structures and drop off lanes for automobile traffic. Over the next 20 years, the rail yard saw a continual drop in business as transportation moved away from the railroad industry. In 1971 Burlington turned over its passenger rail service to Amtrak, and in 1974 Amtrak moved operations to smaller building down the street. Also, in 1974 the Burlington Omaha Station was placed on the National Register of Historic Places. Unfortunately, this didn't revive business or interest in the building, and it fell vacant for the next 40 years.
It wasn't until 2013 that Hearst Television announced its purchase of the Burlington Station. Over the next several years, the building saw a massive renovation, and ultimately KETV (Channel 7 News) moved its operations into the building. In 2016 KETV needed to further renovate the structure, add an exterior bridge to a nearby facility, and add an interior mezzanine. To facilitate this renovation, the load-carrying capacity of the existing foundation system needed to be increased.
Thrasher installed a total of 72 piers at an average depth of 90 feet.
Thrasher Foundation Repair was selected as the contractor of choice to make improvements to the foundation.
To increase the interior foundations' capacity, 20 resistance piers (PP350) were installed on several of the existing footings. Once the existing footing had appropriately been stabilized, and the existing weight was fully transferred to the resistance piers, the soil from below the footing was removed. In essence, the existing footing was placed on temporary stilts. Twenty-four grouted Micropiles were then installed alongside the existing footing. A new supplemental footing was poured on top of the micropiles up to the bottom of the existing footing. Essentially, a new high-capacity footing was built directly below the existing and operational original footing. Once completed, the new and original footings could support the new mezzanine structure to be built as part of the renovations.
On the building's exterior, 28 new-construction grouted micropiles were installed as part of the foundation of a new pedestrian bridge and balcony. In total, 72 piers were installed to an average depth of 90' as part of this historic property's renovation.
This once extravagant and world-renowned Railroad Station turned abandoned and run down, was now back on track to being restored to its original beauty. Within a few short months, KETV completed all the renovations, and the building was now a state-of-the-art broadcast and web media facility. On October 28th, 2015, KETV aired its first broadcast. This once magnificent building had been returned to its original glory and is again an icon for downtown Omaha.
