Ridgedale Pedestrian Bridge | Minnetonka, MN

Western Specialty Contractors – Minneapolis Branch recently contracted with S and S Development to restore a damaged pedestrian bridge connecting the four-story Ridgedale Office Center to its parking structure.

Years of severe winter weather had deteriorated the concrete bridge, and ultimately the collision of a horse trailer into the structure prompted its immediate repair. Western worked directly with the engineering firm Walker Consultants to design a replacement bridge railing system and estimate the repair work.

The scope of work included removing the bridge’s old steel railing system on all sides, replacing the outer concrete edge, and opening the precast plank’s outer core.

After Western removed the concrete, the structural components were inspected by Walker, who put the design into place.

Western then installed new supplemental reinforcing steel embeds into the precast plank structure and poured a new supporting edge on the outside of either side of the bridge. To create the edge, Western utilized a fast-setting, ready-mix concrete from a local plant and placed the concrete using a conveyor system to speed up the process and complete the project before winter set in.

During the construction process, Western workers ran into unexpected damage that prompted a slight change in plans.

“After we removed the old railing, we found that the outermost edge of the precast planks had a shear crack running longitudinally on both sides of the bridge,” said Western Minneapolis Assistant Branch Manager David Grandbois.

“It was determined that this had to be completely removed, and new reinforcing steel had to be embedded into the existing planks to allow for a new concrete edge to be poured before Western could install the new railings.”

Western performed additional concrete repairs on the underside of the bridge and the abutments on either end. After completing all the concrete repairs, Western installed new galvanized railings and applied a traffic coating to protect the newly restored concrete deck.

Western completed the project in two months and within budget.

Offutt Control Tower | Omaha, NE

The Western Specialty Contractors Sheet Metal Division in Kansas City, MO, recently replaced leaking, improperly installed wall panels and flashings covering the control tower at Offutt Air Force Base in Omaha, NE.

Historic Offutt AFB is the headquarters for the US Strategic Command, 557th Weather Wing, and 55th Wing, the largest wing of the United States Air Force’s Air Combat Command. With its history dating back to 1894, Offutt AFB has played an essential role throughout US history, including hosting one of the first major strategy sessions by President George W. Bush in response to the September 11, 2001, terrorist attacks.

With so many crucial military aircraft flying in and out of Offutt daily, it’s imperative that its airfield and control tower function properly at all times.

Western Specialty Contractors was contracted to replace leaking freezer panels and associated flashing on the envelope of the base’s control tower. The damage resulted from improper installation when the structure was built nearly 30 years ago.

Western’s sheet metal experts worked with project general contractor HHI Corp. to estimate/bid the job and design and fabricate a new Dri-Design wall panel system and associated flashings. Dri-Design is a 100% recyclable, pressure-equalized rain-screen architectural metal wall system that attaches to nearly any substrate without using clips or extrusions. Its interlocking design makes installation quick and easy, plus it comes in a variety of colors, materials, textures and custom perforations.

Western installed the control tower’s new metal panel system within a month and on budget. The architect on the project was Kenneth Hahn Architects.

Weeki Wachee Statue | Spring Hill, FL

(St. Louis, MO, September 20, 2022) The Adagio Fountain, featuring a statue of two mermaids in an adagio pose atop a 25-foot pillar, has greeted visitors to Florida's Weeki Wachee Springs State Park since it was unveiled in 1966. Made of vintage masonry, the 56-year-old sculpture was experiencing cracks, spalling, deterioration, and other damage when the Florida Department of Environmental Protection reached out to Western Specialty Contractors – Orlando Branch to resolve the issues.

The iconic fountain's mermaids were created by retired Weeki Wachee “mermaid” Diane Whatt McDonald, 91, of St. Petersburg. McDonald and other women performed as magical mermaids for audiences in the spring's underwater theater – a world-famous roadside attraction that started in 1947 and continues today. The park's spring is one of the deepest natural caverns in the U.S., with approximately 117,000,000 gallons of clear water flowing from it daily.

Western's restoration experts thoroughly evaluated the sculpture before crafting a plan for its restoration. Utilizing boom lifts, workers began the project by thoroughly cleaning the statue and making epoxy patch repairs to all exposed deteriorated locations.

“The extent of deterioration of steel in the mermaid's lower flipper caused crews to treat the steel with caution during the restoration process. Therefore, the statue was barricaded off from pedestrian traffic, and extra care and precaution were taken when we had to completely remove, clean, and re-attach the flipper,”

Taylor Thomas, Western Specialty Contractors Orlando Project Manager

“Western crews worked 480 tedious hours to sculpt and match the art of the original sculptor's work to complete the project and restore the statue to its original glory,” said Western Project Manager Taylor Thomas.

The work also included restoration of the statue's interior steel frame. Workers removed rust from all deteriorated steel, then installed a corrosion inhibitor and a thin set of cementitious epoxy adhesive to align the steel with the curves and details of the mermaids' bodies.

To complete the month-long project, Western applied two coats of a historic protective coating, Neogard Ureprime HS4 Epoxy Urethane Primer (Dual Component Primer), to match the statue's existing color. The clear coat Neogard Acrylithane HS2 Urethane (Dual Component Top Coat) was applied over the primer for exceptional chemical resistance and to protect the statue from future weathering.

Despite any challenges, Western was able to complete the project on time and within budget for the park's visitors to enjoy once again.

Auburn University Stadium | Auburn, AL

Western Specialty Contractors – Atlanta Branch recently tackled the job of restoring the stadium at Auburn University.

The iconic stadium was originally dedicated on Thanksgiving Day, 1939, before the first varsity football game was played. Although known primarily as a venue for football, the stadium has also hosted appearances by evangelist Billy Graham and musicians James Brown, The Beach Boys, Miranda Lambert, and Kenny Chesney, among others, throughout its history.

The concrete stadium seats 87,451 people and is one of the top 15 largest college stadiums in the U.S. Expanded 14 times since its original construction, with significant renovations in 2004 and 2017, the stadium required restoration and maintenance to prepare it for the 2022-23 football season.

Most sports stadiums and arenas in the United States are made of reinforced and precast concrete with steel seating supports and railings. Unfortunately, an even more universal characteristic is their openness and vulnerability to the elements — in addition to the wear and tear they receive from fans — all of these forces take a toll on a stadium’s structural integrity.

Without routine maintenance and protection, these concrete structures are subject to cracking, spalling, and structural damage from movement and reoccurring freeze and thaw cycles.

Western Specialty Contractors worked with Project Engineer Stephen Ward & Associates of Madison, AL, to analyze the type and extent of damage present in the stadium and recommend cost-effective, remedial measures to extend the facility’s life and keep fans safe. Cutting-edge, long-wearing deck coatings are often recommended to restore a stadium and protect it from future damage.

Western switched the primer on the treads to an epoxy primer due to the concrete having a concrete surface profile (CSP) of 8, with the coating manufacturer requiring a CSP of 3-4. The epoxy primer allowed workers to smooth out the overly rough areas before adding sand to the epoxy to give it the correct profile.

Western’s Atlanta team completed the project in August 2022, right on time for the university’s football season to begin.

McLean County Museum Roof | Bloomington, IL

(St. Louis, MO, July 27) Extensive water damage from an aging roof threatened to destroy treasured artifacts housed at the McLean County Museum of History in Downtown Bloomington, IL. The water intrusion resulted from a 30-year-old, damaged roof that had exceeded its useful life span by more than five years, allowing rain to leak through the roof and insulation, clay tile, and mortar down into the building’s ceilings and interior rooms.

The nationally accredited, award-winning museum occupies the former McLean County Courthouse, an American Renaissance-style structure built between 1900 and 1903. The building features a limestone-clad facade and solid masonry construction with a steeply sloping roof connecting the built-in gutter to the clocktower dome rising from its center. The old roof consisted of a 4-ply, built-up asphalt roof over one-inch perlite insulation mopped to the clay tile deck.

Although the McLean County maintenance staff had repaired the roof over the years, it no longer functioned properly and needed to be replaced immediately, along with the historic building’s drainage system. According to reports, as much as 14 gallons of water had leaked into the building after heavy spring rains, causing extensive damage. Although the water had damaged no artifacts, one area of the museum had to be closed off, and an office relocated due to the leaking roof. a 4-ply, built-up asphalt roof over one-inch perlite insulation mopped to the clay tile deck.

“The entire job was very challenging. We had to stage materials on the grounds as we needed them because the old clay tile deck could not be overloaded. Tearing off the old roof every day was equally difficult because we had to crane materials down and up from the street as we progressed.”

Jared Osterman, Western Specialty Contractors Peoria Assistant Branch Manager

In 2020, the McLean County Board agreed to hire Scharnett Architects & Associates of Bloomington to perform architectural and engineering services to replace the building’s roof and improve its drainage system. Western Specialty Contractors’ Peoria Roofing Branch was contracted to replace the historic building’s damaged roof, with work on the project starting in May 2021.

Western’s crew removed the old roof and replaced it with a Firestone UltraPly TPO roofing system consisting of an 80 mil white membrane over gypsum coverboard, Polyisocyanurate insulation, and vapor barrier directly over the clay tile deck.

The architect designed the new TPO roof system to go above and beyond what the manufacturer recommended, with double membrane thick valleys and ridges and built-in gutters lined with TPO and terminated with a liquid flashing, three-course step. The liquid flashing was use in place of counterflashing to minimize the use of mechanical fasteners in the historic structure. The job also required a 30-year, 80 MPH Firestone Roof warranty, including hail, cut, and puncture resistance.

Western’s Springfield, IL Branch also participated in the project by grinding out reglets, reworking the clay tiles around the drain replacements, and cleaning and sealing limestone at the gutter edge.

Performing a successful mock system pull test to ensure the new roof’s viability and strength, Western completed the roof replacement in September 2021. The museum had been closed to visitors during the roof replacement project while its restrooms were remodeled and its lighting fixtures replaced.

Julie Emig, the museum’s Executive Director, noted that the staff was relieved when the roof was restored. “The quality of Western Specialty Contractors’ work, especially given the complexity of this project, was outstanding. We no longer worry that the next rainstorm could damage our award-winning collections and exhibits.”

Waterproof Coating System | UOM Boathouse, MN

(St. Louis, MO, March 11, 2021) The University of Minnesota is one of few universities in the country to boast an on-campus boathouse. Located on the banks of the Mississippi River, the two-story Irene Claudia Kroll Boathouse features a 35-seat erg room, full locker-room, boat storage, coaches’ offices, and indoor tank for the team to practice.

Western Specialty Contractors – Minneapolis Branch teamed up with Minnesota-based General Contractor Gardner Builders to make repairs to the facility’s second floor where the 7,500-gallon practice tank is located.

Over time, water that had splashed or leaked out of the tank had seeped through the existing flooring to the space below. The facility had been constructed in 2007 with precast flooring planks and a nonstructural topping slab.

Gardner Builders removed the tank, failed waterproofing, and installed a drainage system for a new tank.

Western’s crew then repaired the concrete around the new drains, as well as cracks in the concrete slab where the water had leaked through.

After all the repairs were made, but before the new tank was installed, Western installed a new 125-mil Tremco PUMA waterproof coating system to protect the concrete floor and prevent further water leakage.

“The waterproofing is a very heavy duty and durable system that comes with a 20-year warranty but will actually last much longer than that,” said Minneapolis Assistant Branch Manager David Grandbois. “To ensure that the floor was monolithic and free from variances, Western performed an electronic leak detection test on the floor, which found no discrepancies.”

Grandbois said the project was challenged by coordinating the timing of the coating application with work performed by the general contractor and the other trades on the job. Because the facility was closed due to COVID-19 restrictions, the construction team did not have to coordinate their efforts around the rowing team’s activities.

The project started at the end of November 2020 and was completed in March 2021.
