Nassau 8th Precinct
Following Hurricane Sandy in 2012, many structures owned by Nassau County in New York state were evaluated for structural damage, including the police precincts. Prior to the storm, several of these buildings had already been in need of renovations to accommodate a growing police force and resolve problems of aging infrastructure, and the storm accelerated this need, says Gilbert Balog of LiRo Architects + Planners.
In the 8th District, Nassau County wanted to replace the 1950s-era frame and brick precinct buildings with structures that communicated civic pride and could withstand the onslaughts of future major events. “Resiliency was a major factor in the selection of precast concrete construction,” says Dianne Pohlsander, design architect for LiRo. “In fact, everything came together with precast concrete: resiliency, fabrication that wasn't weather dependent, constructability, and the desired aesthetics.”
Precast concrete also helped address unique logistical challenges on this project. Construction was constrained by long and narrow site, and, because the new precinct house was constructed at one end while the old building stayed open for operations at the other, the team was under pressure to complete the project quickly with minimal site disruption. “Precast concrete gave us that quick erection time that we needed,” Pohlsander says.
Key Project Attributes
Off-site fabrication compressed the on-site construction schedule, minimizing disruptions, and avoiding weather delays.
The all-precast concrete design contributes physical resiliency to the structure, while visually communicating a sense of permanence and security to the public.
The envelope features energy-saving precast concrete sandwich wall panels with a 2½-in. thick layer of expanded-polystyrene foam to ensure a continuous insulation R-value of 12.
Majestic County Seal
Aesthetically, the highlight of the new precinct’s design is the heraldic lion of the Nassau County seal, which reinforces the building’s county identity and was cast directly into the precast concrete façade using a CNC-cut foam mold. The facade also features exposed, buff-colored precast concrete panels with an acid-etched finish detail that reflects the traditional building features found in the community. The first-floor panels are set off with a base of polished pink-and-gray Grigio Sardo granite. On the second and third floors, schoolhouse-red and dark manganese iron-spot thin bricks are placed in running bonds and soldier courses to organize the window openings and emphasize small changes in the plane. “We maximized the three-dimensional plasticity of the concrete surface and used changes of material and brick pattern to enliven the facades,” Pohlsander says.
Inside the structure, the design uses hollow-core planks with 32-ft spans supported by just six columns to create expansive open-floor areas. Large “punched” windows in the concrete panels provide ample natural lighting while the wall area between windows allows for flexible placement of interior partitions. “Precast concrete offers simplicity of structural design and functionality in space planning,” Balog notes. “The county and the officers are very happy with what we delivered.”
