PCI has published a series of design manuals and design guidelines to provide technical support for the development of American prefabrication industry.
PCI’s official website provides profiles of nearly 600 precast buildings.
This series selects some typical examples and shares them with you.
According to the building type, this series is divided into parking lot, residence, plant and road and bridge.

Edwards industrial advanced Honor Award • Sidney Friedman craft Award – 2020 award winner project overview onesouthfirst is a new comprehensive use building in Brooklyn, New York, which is expected to redefine luxurious coastal life.
This building overlooking the whole East River, with 42 storey residential tower and 22 storey commercial tower, was once the location of Domino’s old sugar factory.
The new owner sees the potential of the plot to be built into a luxury coastal living area, and hopes that the design appearance of the building can maximize the use and enjoy the waterfront scenery.
The architect incorporated the crystal molecular structure of sugar into the envisaged modern appearance to connect the new building with the industrial history of the region.
“It reminds us of the sugar manufacturing process,” said PAM Campbell, a partner of cookfox and designer of the project.
“We really want to create a dynamic architectural appearance, which can remind people of the reflection and structure of sugar crystals.”.
They use precast concrete to realize this idea.
The precast concrete facade is characterized by the repeated use of white precast concrete with angle and deep interlocking panel, which is used to create the game of light and shadow and make the rigid appearance vivid.
In terms of design, each facade can self adjust the shielding according to the specific sun direction, and self optimize to reduce the energy use during cooling.
“It provides a unique opportunity to prioritize energy efficiency through the complementarity of different uses of energy,” said Steve Schweitzer, vice president of operations of gate precastcompany.
The window is deeply opened, and its sides have different angle sections to capture light and show the glittering sand in the white concrete after acid etching.
The front face of the panel is polished to provide a smooth reflective surface to supplement the pickled surface.
The mold layout in the panel is different in the whole building, so the appearance design has a randomness.
Each mold can be poured 200 times.
In addition to helping designers achieve their aesthetic goals, using precast concrete to make the facade can also save a lot of time and money.
To make this exterior wall, precast concrete manufacturers used 3-D printed molds in a process called additive manufacturing.
3-D printing die makes it possible to quickly produce a large number of panels with window holes.
Schweitzer points out that the mold manufacturing of this project generally requires 40 to 60 man hours.
But with automated 3-D printing, the time was compressed to 14 hours.
Each mold can support more than 200 casts, while traditional wooden molds usually need to be reworked after 16 to 18 times of use.
This allows the production team to manufacture the exterior wall without stopping for several days.
Throughout the project, the design assistance team uses Revit software to plan and track all phases of the entire building life cycle.
They created an “intelligent family” in the software to achieve rapid advancement and collaboration among teams..
