The new mixed-use structure at 5th & Race Street in Cincinnati, Ohio, gives visitors the impression that they can see right through the building. Designers of the 280,000 ft² facility, elegantly merged broad windows and precast concrete panels to create a light and elegant building that reflects the blue sky during the day, and golden street lights at night, while giving residents a strong, open space for their offices and retail.

The building, titled 84.51° Centre, includes a 1000-space, four-story parking garage at the base topped by four stories of commercial space. Precast concrete was chosen to achieve the owners’ durability, accelerated timeline, and aesthetic goals, says Glenn Ebersole, P.E., Market Development Manager of High Concrete Group, the precaster on the project. “By using architectural precast panels we were able to provide the dark color and avoid the repetitiveness of patterns while limiting erection time.” The dark color of the precast concrete was created by combining black granite coarse aggregate with black sand in the mix. The panels were acid etched to provide a soft texture, sometimes referred to as sugar cube texture. The acid etch finish also enables the sand to sparkle in the sun, providing glints of light and visual interest to passersby.

“The use of precast to provide ventilation on the garage level helps camouflage the fact that the lower levels of the building are a garage and it creates a unified facade,” says Michael Zensen, Associate Vice President, CannonDesign, one of the judges of the 2016 PCI Awards committee. The horizontal reveal pattern provided the desired modern, industrial look, and random non-symmetrical window openings combined with reveal accents added visual interest.

Perched up above a seemly 6-story precast podium parking garage stands a hotel and apartments that rely on the durability of precast to provide key functionality to the structure. While the garage is an open design for natural ventilation, the designers observe a balance using large wall panels with a square reveal to create the visual of sectioned windows on a standard building. Being able to factor in the finished material by augmenting another material elevated off the precast panels was a benefit to using precast concrete on this project to create the feel of a cohesive building and not a parking garage.

The precast columns stream down through the 380 car parking garage into the ground level to structurally support the garage as well as the steel structure placed above the garage. The structural capacity and durability precast brings are essential to the harsh weather climate that this structure will come into play with.

The first level of structural elements complements the functionality of the building ground level by acting as a ceiling that completely seals an operational facilities portion of the hotel and several retail/food services tenants. A waterproof sealant was applied to the structural elements on the first precast level to keep the moisture out.

Located in a city neighborhood, the FDNY rescue facility was designed for an elite force of specialized rescue workers to stage and simulate a wide range of emergency conditions. The members of the rescue company train to respond to various emergency scenarios, including fires, building collapses, water rescues, and scuba operations.

Big building, small space

Established in 1718, Lancaster is the oldest inland city in the United States. Its town square can be traced back to 1730 when James Hamilton laid the city out in a traditional grid. Structures with lasting, historical value have been fixtures on the square for years. The central area has always been among the most densely developed parts of the city.

Certainly, constructing an intricate project, Lancaster County Convention Center, that would bring new architecture to an established, compact downtown would require imagination and thoughtful planning. Knowing that precast could solve many of the potential issues, architectural firm Cooper Carry engaged High Concrete Group LLC from the earliest planning stages.

The biggest obstacle consisted of working around the existing structures, many of which would be integrated into the new complex. It severely limited the size of the construction site. Because precast is manufactured off-site and delivered to the job as needed, it was preferable over field-built options that would have required significantly more space.

“Staging was a big issue,” explains Kevin Iddings, general manager of Midwest operations for High Concrete Group. “We developed a regimented schedule that allowed us to ship the precast pieces one at a time as they were needed. It helped avoid a backlog of materials in the field.”

In addition, High worked with the architect to simplify the job as much as possible, eliminating unnecessary pieces and identifying ways to reuse molds, thereby minimizing costs.

Integration

The TQL Ivy Pointe Office building is predominately thin brick-clad with light sandblasted buff-colored precast details framing the spandrels. The precast provides a face-sealed curtainwall that provides effective moisture control that typical rain screen construction cannot.  The thin brick is finished with a rake joint.  Additional precast details include a 2-1/2’ projection below the parapet to lend a dramatic shadowline.  The parapets themselves are at a height of 42” over the roofline to allow maintenance and other personnel to work on the roof without tying off.

The design made repeated use of a few stacked panel designs, allowing maximum economy.  L-shaped thin bricks wrapped around window returns as would a full depth brick course.   Formliner created a stone look formliner to the columns at the main entrance to add to the feeling of solidity.  Reveals add drama and break up the mass to create a human scale.

When planning to construct a new performing arts building, Villanova University weighed the many options for construction materials. As part of the University’s project to transform a previously underutilized parking lot into a multi-use area, including student housing, retail, and dining, the performing arts center acted as the crown jewel of the development. Through this development project, the University intended to provide the local metropolitan community an opportunity to experience new forms of art and culture, while also using the facility as a hands-on learning experience for theatre students. To achieve this vision, the structure needed to house a full-size theater, along with studios and classrooms, and provide adequate acoustic isolation between the spaces. Villanova is known for its Gothic-style architecture across campus, so the new design also had to complement the aged architectural style of its surroundings. Creating precast panels with plant-installed stone could meet the aesthetic and functional needs of the university with lower costs and construction time than a traditional stone façade.

The UPMC York health campus is home to three precast concrete enclosed buildings.  These buildings have very similar qualities to each other but stand alone. Each building has the same color scheme using a light color with a sandblasted finish and a dark charcoal color with a duxberry formliner. 

The hospital contains more individualized rooms where each window is framed with a unique precast portion that protrudes out. The elevation around the windowsill grows from a flat side to about a 3-inch elevation on the other side. This creates beautiful shadows framing the windows themselves. 

The surgery and cancer center is more of a full-floor unit. You can identify this portion by the picture frame windows that span the whole floor. These windows also have projections, but they run from top to bottom compared to the hospital windows that run left to right. 

The last building on the campus is the central utility plant. This building is home to all the HVAC and generators to support the other two buildings. With the exposed roof and design of the hospital and the surgery and cancer building, they did not want to house these items on the roof of the buildings. As a result, the facility nearby houses all that is needed to help maintaine the other two buildings. 

When a new multi-use parking garage was needed at the Newark EWR airport, the New York/New Jersey Port Authority explored various building solutions and ultimately chose precast concrete for its ability to meet the unique needs of this one-of-a-kind parking garage. The garage's design allows natural ventilation, and provides convenient public parking, access to all car rental companies, and solar panels in one centralized location. The garage needed to support both public and private parking for the new airport terminal and consolidate rental car facilities for the airport.

With a focus on sustainability becoming more important in new construction, the design of the parking structure needed to support the weight of 12,708 solar panels, that cover 364,00 square feet, and generate enough electricity to power 800 homes. Precast concrete was the best choice for the structure because it can handle the weight of the largest single solar rooftop of any United States airport.

The facility also features 150 electric vehicle chargers available for public use.
The garage is composed of 6,344 pieces including four helixes. An exterior ramp which connects the ready return and public parking as well as the quick turnaround portion of the garage. The ready return has approximately 5,000 parking spaces and the quick turnaround adds an additional 904 spaces.
