Simons Center for Geometry & Physics at Stony Brook

Simons Center is new building on the Stony Brook campus which features a glass and metal kinetic art wall manufactured by Zahner. Designed by the architects at Perkins Eastman, the new facility brings a world-class mathematics and physical sciences building to the Stony Brook University in Long Island, New York. The building’s most intriguing feature is the animated stainless steel kinetic surface.

The kinetic panel system first began early development in 2008, when Zahner began working on a series of projects with the renowned kinetic artist and designer, Chuck Hoberman. Hoberman foresaw a future where kinetic surfaces could respond to environmental changes (such as temperature, moisture, and light) by opening or closing an aperture on the surface of the building itself. Today these systems are now possible, and the new Center for Geometry and Physics at Stony Brook provides an early prototype.

Perfectly Perforated

Over the early 1990's, patterned usage of perforated metal began to appear. At the time, the pattern were limited by programming. It wasn't until the early two-thousands, when Herzog & de Meuron designed the de Young Museum, that perforated metal would truly enter into its own.

Several patterns designed by Hoberman Associates are featured on the interior of the new Stony Brook Facility, serving as both the building’s artistic centerpiece as well as a functional shading system. The floor-to-ceiling metal surface is made by layering four panels manufactured in perforated stainless steel. Three of the layers are motorized to open and close based on temperature requirements.

Each of the motorized panels revolve around one another on an engineered track defined by the designed components. The visual effect is like that of a flower, blossoming into a burst of patterns – hexagons, circles, squares and triangles. At one point in the cycle, the perforated patterns all are aligned, allowing the maximum open space. At the other end of the cycle, the pattern becomes an opaque mesh.

The kinetic surface spans 124 square meters and imbues the building with the functional capacity to dynamically change its opacity and sculpt the quality of light within.

Standard Parking

Standard Parking Garage at 11th & Oak

Designed by George Butler Architects for the Power & Light District of Downtown Kansas City, this is a parking structure’s facade was constructed using stainless steel as well as perforated aluminum surface to allow airflow for an otherwise congested space.

The aluminum screen wall was engineered, custom perforated, and installed as an facade panel system. The system also has uses for unusual panel sizes and unique details, as was the case with Standard Parking. Each of the panels was installed using an the Inverted Seam dry-joint system for integrated walls. The cornice and bold stainless steel fins were engineered, fabricated and installed to digitally defined coordinates.

Building the Standard Parking Garage

Zahner developed the design for Standard Parking Garage using drop and lock details to enable quick and simple installation. Each of the panels locks into anchored connections on the concrete structure. This enabled a rapid schedule for the project’s facade.

The above photographs were more than a decade after the project’s completion. Stainless steel is often chosen over aluminum due to its high-performance sheen which never dulls and requires no maintenance. Aluminum is more porous, and over time it begins to dull, but this is not yet the case with Standard Parking Garage screen-wall.

Silver Towers

Silver Towers Courtyard Trellis in New York

Silver Towers is a development in New York City which features Zahner manufactured perforated metal and glass systems. The courtyard, plinth and rooftop terrace design by James Carpenter Design Associates, brings an artistic approach to both the facade as well as the landscape for the residential project.

Between the two high-rise towers is a six floor plinth, the interior courtyard of which features a 75 foot light wall. Various metal and glass light fixtures which feature the artist’s pattern.

Zahner was hired by the architect to design, engineer, and fabricate these metal and glass systems. Each of the fixtures features a perforated metal floral pattern designed by the architect, contained within a glass and stainless steel lightbox.

Also known as River Place II, the project features two 57 floor twin towers and is located in the Hell’s Kitchen neighborhood of Manhattan Island. The project was developed by Larry Silverstein and completed in 2009.

San Francisco Municipal Transportation Agency Ticket Kiosks

The SFMTA Ticket Kiosks are a series of ticketing booths in San Francisco for accessing the cable car envisioned by Lundberg Design. Zahner manufactured the custom perforated metal components for the San Francisco Municipal Transportation Agency. The designers wanted to wrap the top of the booth with imagery of the historic cable cars.

This effect was elegantly achieved by perforating the surface of stainless steel to create the light and dark tonal values of the original photographs. To achieve the mosaic-perforated imagery, ZIRA patented technology was used (designers can now create similar designs using ImageWall to generate custom perf).

This technology enabled a smooth translation of the designer’s imagery to metal while also also ensuring panel-to-panel relational accuracy. This is crucial on a project such as this: The imagery is divided into a series of panels and wrapped around the sides of the small structure, so it was important that the perforations on each panel lined up with the next panel.

Developing the 911 Museum Metal Facade

The panels were tested for wind loads and water permeability at a special facility. The panelization method used for the project required welding studs to the reverse of each panel. Zahner-trained fabricators welded the hardware at ideal penetration so that the stud-welds wouldn’t show on the face of the metal panels.

The surface of the metal shell alternates between GB-60 polish and a No. 4 polish on stainless steel. The No. 4 polish has greater reflectivity along a linear grain, while the GB-60 surface scatters light for a more diffused look. This alternation repeats itself as a motif in not only the stainless steel facade, but also across the fenestration surface.

San Diego Central Library Donor Features

Signage, artworks, and architectural features designed by Luce et Studio are featured throughout the new nine-story San Diego Central Library in downtown San Diego. The features include an illuminated mast which spans four floors on the building’s North exterior, a massive-scale replica of an orchestral bow on the exterior of the ninth floor, and custom signage to celebrate the donor spaces throughout the library.

Donor Recognition

Throughout the building’s nine stories and exterior spaces are various signifiers, art elements, and architectural features which created to recognize the generous donations made by the philanthropic community in San Diego. The Central Library’s funding is unusual for a civic building, because forty percent of the costs were covered through private fund raising, including the operational costs of running the library. The private support means that the library was built with no new taxes, bonds, or moneys from the city’s general fund.

Architectural Signage

Signage and wayfinding design has transformed over the years from a purely utilitarian and informational, into art and design. Finding ways to make signage both useful and aesthetic has been a goal of the design-engineering and fabrication at Zahner for many years.

The Mast at San Diego Central Library

Luce et Studio’s design for The Mast for San Diego’s downtown Public Library was designed as a 70′ tall aluminum column, whose diameter ranges from 8′ at its top and bottom, and 12′ at its median.

The Mast is constructed in aluminum with varying perforations which run up around its length. Inside of the mast is an interior LED lighting system, which provides a beacon of star-studded lights which illuminates the facade throughout the evening hours. The mast was manufactured by Zahner in Kansas City, and installed by a local team in San Diego.

Joan & Irwin Jacobs Common

At the building’s South entrance are multiple signage elements for the San Diego Library Joan & Irwin Jacobs Common, recognizing the philanthropist team who donated $20 million towards the library’s operational costs.

The technique used to create the building’s southern pedestrian level signage is a signature style developed by Luce et Studio on an unrealized project for Hotel James (pictured below). The signage concept was developed by Jennifer Luce to create a third dimension for the cut-out letter shapes. Zahner manufactures a groove in each of the letters, which allows the letter to then be folded out. The concept was first created years prior, and is featured prominently as a notable signage display for the San Diego Central Library.

Library Bar Code Signage

One of the themes that moves throughout the entirety of the library is a bar code motif, extruding from the letter forms of various donor plaques and signage elements on both the interior and exterior surfaces of the library. The extruded letter forms also break planes and wrap around columns, walls, and concrete boundaries.

The thick metals used in the custom signage include stainless steel and bronze, and included areas that are painted, as well as areas that let the metal surface shine through, much of which uses Zahner’s Angel Hair mechanical non-directional surface treatment.

Ricardo Regazzoni Sculpture at Georgetown, Qatar

Forty reflective spiraling forms appear to float above the atrium at Georgetown University’s School of Foreign Services in the capital city of Doha, Qatar. Completed in 2012, this project marks the fourth significant work produced by Zahner in Doha, and the second produced under the vision of architects Legorreta + Legorreta who designed the building for Georgetown University at Doha as well as the HBKU Doha University Student Center a few blocks away.

The artwork at the heart of Georgetown University was conceived by sculptor Ricardo Regazzoni, engineered by Zahner, fabricated in the Zahner shop, and installed by local installers in Doha under Zahner supervision. Each of the forms measures 38’ long, and the artwork fills an area of 82’ x 131’ over the open atrium.

Collaboration between Zahner and Regazzoni is a match of of kindred philosophies. While Regazzoni works to transform architectural columns and archways into artistic expression, Zahner works to bring architecture into the realm of art. This alignment of sensibilities between the artist and fabricator gave this project a strong sense of direction.

Design Assist for Art: The Regazzoni Sculpture

In late 1990s while working with Frank Gehry on the EMP Museum in Seattle, Zahner coined a term which has become the industry standard for building complex projects: Design Assist. The museum’s complexity required that Zahner work closely with Gehry’s office to develop the design. Design assist was first used to describe this process. Since then, design assist has become widely known as the most intelligent construction method for achieving efficient and cost-effective production of complex architectural projects. Along with frequent partner Metalabs, this process is now being applied to art.

The Regazzoni Sculpture details were developed by Zahner’s think tank of installers, engineers, and fabricators: the Design Assist team at Zahner. This group of engineers and consultants worked together with the artist to develop a system which could meet both the functional and visual standards. The team developed a mockup to test the drawings and construction processes.

From Mockup to Installation: The Regazzoni Sculpture

Regazzoni’s undulating, diagonal forms were extremely intricate, requiring specialized engineering and attention to craft during every stage of their creation: from design, to fabrication, to installation. Working within Regazzoni’s vision, Zahner’s Design Assist team developed specialized details for the connections of each intricate geometric part.

Zahner began by producing a mockup of the artist’s design, providing a model that revealed the connections and provided a template for the components. The design features a weld-less connection system. It was important to eliminate welds so that the mirror-polished surface would be free of any discoloration from the welding process.

The resulting surface minimizes the appearance of fasteners, and weld discoloration. The headless pin system is almost indiscernible to the naked eye, and the connections prove to be every bit as strong as welded joints: each connection is capable of supporting 600 kilos, or five times the hanging sculpture’s weight.

Shipping the Regazzoni

Due to its complex geometry and elongated form, the Regazzoni was susceptible to bending during shipment and transportation. To accommodate for this risk, Zahner designed custom lifting rigs and crating to ensure that the piece arrived at the installation site in good condition. Below is an example of the crating, which was custom-built to efficiently and safely ship the pieces overseas to Doha, Qatar. Zahner is committed to the integrity of an artist’s vision, from the preliminary stages of design to shipment and the final days of installation.

The artist wanted a visual masterpiece with concealed connections, so that each form appears to be suspended by magic. Zahner’s biscuit extrusion is used to attach the metal tendrils to the ceiling.

Building Art & Architecture

Together with the Metalabs art services team, Zahner has completed over 70 public and private works of art for both established and emerging artists. Working with artists has expanded Zahner’s research and development team, which has in turn provided many innovative surfaces, processes, and techniques applicable to both art and architecture. Zahner’s team of engineers and fabricators have proven flexible to many kinds of projects, and have produced works of many scales.

Jay Pritzker Pavilion at Millennium Park

Pritzker Pavilion is a one-hundred-foot proscenium located at the North end of Millennium Park in Chicago. Designed by Frank Gehry Partners and manufactured with structural forms by Zahner.

The project consists of fourteen distinct forms, which visually appear as a cohesive whole. Each of these distinct forms is made using a straight stick steel primary structure. A secondary structure manufactured by Zahner attaches to the primary and is then clad in stainless steel by Zahner.

Each of these fourteen shapes serve to form the bandshell, providing protection from the elements while creating a focal point at the stage and orchestra pit of this dynamic outdoor amphitheater. Architects at Frank Gehry Partners began working with Zahner on this project in 1999, which was completed in 2004.

In total there were 697 prefabricated assemblies shipped to the jobsite. These assemblies were clad with over 3,000 stainless steel sheets measuring 2′ x 4′ on average. The sheets used for this project are 22ga Angel Hair finish on A316 stainless steel, a high performance stainless steel alloy containing molybdenum, a metal which provides high corrosion resistance for the metal.

The structure reaches a height of one-hundred twenty feet. In several areas, the structure curves back on itself, becoming nearly horizontal. The metal surface of this project is clad in stainless steel with a custom flat seam panel for dual curvature. The near-flat surface it creates, allowing the viewer to focus on the entirety of the shape rather than being drawn to the individual lines. According to an interview with the architect, the proscenium was inspired by Gehry’s 2001 flagship store for Issey Miyake in New York City, a sculptured titanium also made with Zahner.

These column covers consist of heavy-gauge stainless steel plate panels rolled to shape and attached with interior fastening system. The columns range in height from 12’ to over 24’ .

Each of the column covers is clad in a 10ga stainless steel, a heavier gauge than the 22ga stainless steel cladding the proscenium.

The Petersen

The Petersen Automotive Museum in Los Angeles, California:

Situated on Los Angeles’ famous Miracle Mile, the newly renovated Petersen Automotive Museum has achieved an iconic status while creating open spaces which invite community engagement. The design encases the building in a red-painted corrugated aluminum rainscreen system which acts as the backdrop for a series of stainless steel structural ribbons. These scopes were engineered, manufactured, and installed by Zahner.

Designed by Kohn Pedersen Fox (KPF) in New York with the construction management by Matt Construction in Los Angeles, Zahner was brought onto the project early on in the planning and development process. Starting under a Zahner Assist (Design Assist) contract, the construction team developed a fabrication and installation strategy with the engineers at Zahner.

This is the second project completed by Zahner with KPF. The two teams worked together prior on the IBM Headquarters in Armonk, New York.

Making the Petersen Automotive Museum

Design development for the Petersen Automotive Museum began in 2012. Principal Trent Tesch knew that the complex shapes would be best defined under a Design Assist contract with Zahner. Examining the forms gave the team an opportunity to approach their design with as much information as possible. Zahner Assist enabled KPF to bring the client into a conversation with Zahner.

Sharing models and preliminary drawings while the design was still conceptual allowed for conversations regarding costs and aesthetics to remain transparent, assisting the client during the decision making process.

The project made use of several Zahner technologies and methodologies: the ZEPPS Process for designing and manufacturing the building’s curved forms; the Angel Hair non-directional surfacing applied to each of the stainless steel skins attached to the curved forms; and Zahner Assist, Zahner’s method for developing complex projects into factory-produced realities. The project also includes an ImageWall custom perforated metal screen which continues the architect’s design, mimicking the stainless ribbons in a perforated metal graphic across the building’s parking structure. The Petersen Automotive Museum is the direct result of a design team confidently departing from convention.

The Mock Up as a Design Catalyst

As part of the Zahner Assist contract, we included a to-scale visual mockup. Mockups are included as part of this process in order to aid in design decision making and determine the best method for building any given form. The team selected the lower northeast corner of the building’s design to fabricate as a mockup section. This empowered the design team to determine how the ribbons would wrap around the corner, an integral aspect of the building’s design.

The mockup process provided Zahner crucial insight into how to best develop the red-painted structural steel armatures which are used throughout the project. The mockup also helped the design team establish the ideal color for the painted corrugated aluminum surface.

Creating the new Petersen Automotive Museum facade

The existing building, purchased by the Petersen Automotive Museum in 1994, was rectilinear and fairly straightforward in form. It was originally a department store. Six years after the store closed, museum founder Robert Petersen chose the site to house his automotive museum. Since the Museum is nearly devoid of windows, the site was ideal for safely housing Mr. Petersen’s collection without harmful exposure to sunlight.

Because the existing building contained very little glass and was box-like in form, it acted as a blank canvas for the design team. ZEPPS, the Zahner system for developing sculptural forms, was used to build curving stainless steel ‘ribbons’ which wrap the building, giving it a feeling of rapid motion. The result looks similar to the aerodynamic flow diagrams drawn in wind tunnel tests by automotive designers.

Using ZEPPS to Create Dual-Curving Forms

To build complex dual curving forms with the lightest structural loads, Zahner uses the ZEPPS process. ZEPPS stands for Zahner Engineered Profiled Panel Systems, and comprises Zahner’s approach to building complex, curvilinear forms. The crux of the system is the paring down of a complex design into manageable parts for manufacturing.

Using an architect’s 3D model, Zahner’s engineers examine geometry with a manufacturing mindset. Each curve is analyzed and developed into a series of patented aluminum structural components. These components are pre-assembled at the shop and compose the structural form for each ZEPPS Asssembly. Using aluminum extrusions rather than steel allows for a lighter load on the structure of the façade, and also allows for more economical fabrication methods.

The final step in creating with ZEPPS is to clad it in surface material. For the Petersen Automotive Museum, Zahner’s Angel Hair Stainless Steel surface was selected. After the structure is built, each ZEPPS is clad in the desired metal, and loaded onto a truck for field install. By breaking dual curves into units, ZEPPS creates precision within the manufacturing process, and allows for much quicker field installation.

Structural Steel

A new structural steel exoskeleton was needed to carry the loads from the red corrugated rainscreen as well as the cantilevered stainless steel ribbons which arch over the rooftop to provide shading for a private event space.

Working with the designers’ 3D models, Zahner’s team of engineers developed a series of tree-like forms in structural steel to support the ZEPPS Ribbon assemblies. The structural steel skeleton was inspired by hot rod manifolds to serve the dual purpose of providing aesthetic cohesiveness as well as functional support for cantilevered elements of the design. The structural ‘trees’ support the ribbons that flow over the roof area, as well as the Fairfax Ave ground level ribbons.

The ZEPPS ribbons required custom curved structural steel within each unit. Zahner mapped out each curved radius using the 3D model, allowing for fabrication in the shop to be handled quickly and precisely.

Custom Corrugated Aluminum

Painted aluminum acts as the backdrop for the stainless steel ZEPPS forms, echoing the concept of a sports car in bright red intensity. The aluminum was completely custom, and unlike any standard corrugated pattern. The corrugated profile formed an exact 90 degree angle, versus the typical sine wave that is commonly seen in corrugated metals.

To accommodate for the custom nature of this design element, Zahner formed each of the corrugated panels in house, utilizing a custom die within the press brake.

ImageWall Screenwall for the Petersen Parking Enclosure

As a continuation of the stainless steel ribbons, the design team also selected a painted red aluminum ImageWall for the Museum’s Parking Garage. Using Zahner’s patented technology, ImageWall uses perforated holes to map an image across multiple panels. In this case, the image provides cohesiveness, and ties the parking garage in with the larger facade.

Nissan Styling Studio and Technology Center

Nissan Design America commissioned Luce et Studio to design an elegant courtyard for the Nissan Design Group, where the company’s design team could privately showcase its new technologies and concept cars. Zahner worked with partners Wallace Engineering and Turner Construction to produce the courtyard for the campus.

Completed in 2005, the Nissan Styling Studio features a double layered perforated metal skin which has an offset spiral, 30 feet into the sky. The perforated screen allows light to enter while preventing viewers from peering in from the outside. This was a key aspect of the design, because the courtyard was used to display concept cars that weren’t yet available to the public. The oval shaped space at the Farmington Hills Facility is known as ‘The Egg,’ an exterior courtyard where final prototypes could be viewed in natural daylight.
