151 E Wilson
This post-tensioned concrete structure rises 17 stories above John Nolen Dr, offering fantastic views of Lake Monona and the Wisconsin State Capital. The narrow building is built tight between a 100 plus year old 9-story building and 16-story condo building. The 202,000 square feet project features 13 stories of residential units, one-story of retail and office space at the street level and 3 levels of parking below E Wilson St. The narrow site required careful coordination of the new foundations to minimize the amount of underpinning of the adjacent building foundations. The buildings narrow width required that the stair and elevator cores be oriented parallel with the long dimension of the building to maximize parking efficiency. This greatly reduced the effectiveness of the concrete shear walls. To compensate for this, the PE team utilized thickened slabs near the stair and elevator cores to engage adjacent columns to limit the building drift under lateral loads.
833 E Michigan
A new 18-story office building with parking on lower floors. At the Galleria level, there are connecting pedestrian skywalks to the adjacent US Bank Galleria and parking structure. The building has an outdoor deck area and a four-story open lobby space. The tower construction is composite steel framing. Lateral load is resolved through steel braced frames and concrete shear walls. The building is founded on a central mat and isolated spread footings.
The project is comprised of a 2-story precast concrete parking structure, two levels of composite steel and six levels of cold-form metal framing. The building boasts floor-to-ceiling windows on the 10th floor to allow extensive views of the Wisconsin State Capitol from the top floor restaurant. Conventional spread footings support the ten-story hotel and two levels of underground parking. The underground parking features a lift system that allows two vehicles to be parked on top of each other. The six levels of pre-manufactured cold-formed steel wall panels provided a shorter construction cycle.
Acuity Corporate Office
This project was a major expansion of an existing corporate headquarters campus. It added 450,000 square feet of new office space on three levels, including dramatic galleria spaces. Other unique features include a 2,000 seat, two-tiered, circular auditorium, an interior Ferris wheel, and two monumental stairs with cantilevered intermediate landings. In addition to the office expansion, this project also consists of two parking structures with integrated utility plants. Subsequent projects also included a recreation center and an additional parking structure completed in 2021.
17,000 square feet steel-framed climbing gymnasium with roof joists spanning 80 ft on top of a steel braced frame structure, creating an open climbing area with 43 feet clear height. Entire structure bears on top of precast concrete framed lower level parking. A 3,000 square feet mezzanine is provided on the west face to support bouldering areas. The building is clad in weathering steel, glass and metal panel. Significant wall framing coordination was required with the rock wall designer/fabricator for support of the rock wall loading.
The project consists of two six-story composite steel framed office buildings and a four-story precast concrete parking structure linked by enclosed, steel framed pedestrian bridges. Composite steel framing was selected for the buildings to minimize interior columns and increase ceiling heights while lateral stability is provided by concrete shear walls at stair towers to maintain brace-free elevations around the buildings’ glazed perimeter. The combination of 32' wide x 36'-40' long composite framed bays with concrete shear walls provides efficient, open interior space. Conventional spread footings support the two 100,000 square feet office buildings and 590 stall parking structure.
This 11-story, 410,000 square feet mixed use facility features 124 market rate residential units, 17,000 square feet of retail, 42,000 square feet of office, 200 stall parking garage, amenity terraces on the 4th and 11th floors and an attached 60,000 SF youth arts center. Located along the booming East Washington corridor this post-tensioned structure offers dramatic view of both Lake Monona and Lake Mendota. The inclusion of the youth arts center posed a unique challenge for the design team, placing a 300 seat performance theater with full fly space over the top of a three-story parking garage. To provide optimum sound performance in the theater the floors and walls needed to be acoustically isolated from the parking garage below. This isolation was achieved with acoustic isolation pads located between columns below the concrete beams supporting the floor, CMU walls and steel framed roof over the theater and fly space.
Ascension Wisconsin Health Center
A 72,000 square feet, 2-story medical office building with no basement. It has a steel-framed skeleton utilizing moment frames, composite floor beams and solid web roof beams. Project includes a vaulted roof over the patient waiting area.
A new 25-story office building with parking on the lower 10 floors. The building is almost entirely clad in glass and features a three-story lobby space, and exterior patios on the 11th, 12th and 25th floors. The lower ten levels are post-tensioned concrete and the upper levels are composite steel framing. Lateral loads are resolved via brace frames and concrete shear walls. The building is founded on a 7 feet thick mat slab that covers the entire area below the tower.
This new corporate office is four stories plus a full basement for parking. Total occupiable area, including the basement, is in excess of 130,000 square feet. There is a thin profile roof overhang on all sides. There is a single story area at the southwest corner of the building, with an occupiable roof. The roof pitch was intentionally configured to give the roof the appearance of a dish.
BayCare Clinic's Lakeside Campus
Steel framed medical office building with approximately 32,000 square feet footprint, and 11,000 square feet partial second floor, resulting in an approximate total area of 43,000 square feet. The roof is primarily open web steel joists and steel beams. Floor framing is composite steel. The main entry features a prominent canopy, which utilizes connections that have thermal isolation. The lobby/patient waiting area is a dramatic, two-story tall space.
This 220,000 square feet, four-story apartment complex consists of three separate buildings housing 83 total rental units. There are also two parking levels, with one of the levels below grade. The project features multiple balconies and patios.
