1500 Mission Street Atrium Lobby Public Art Project Artist Proposals

1500 Mission image.jpgThe San Francisco Arts Commission is supporting the 1500 Mission Street Capital Improvement Project with the commission of a signature public artwork. 1500 Mission Street is being developed by the City as a permit center and office building that will be occupied by several City departments including Building Inspection, Planning, and Public Works. The new City building will be a 16-story tower on 11th Street between Market and Mission Streets, and the newly commissioned large-scale artwork will be suspended in the three-story atrium lobby of the building. The artwork is intended to create a sense of place, as well as delight and visual engagement for the building’s users. Four artists were chosen as finalists by a Public Art Selection Panel to create site-specific proposals for the 1500 Mission Street Atrium Lobby opportunity: Sanaz Mazinani, Tomás Saraceno, Ranjani Shettar, and Sarah Sze.

Surface

by Sanaz Mazinani

Surface_Sanaz_Mazinani_082817.jpgHome of the Planning Department, Building Inspection, and Public works, the 1500 Mission Building will be a significant hub for the growth, development, and sustainability of San Francisco. These departments work tirelessly together to create a better life for the City's citizens. Surface explores the ways in which these departments reflect the needs of the public through a transparent generative process where ideas and actions commingle, innovate and move the city forward.

In order to express these relationships, Sanaz Mazinani will employ techniques of data visualization to create an abstract landscape of the City of San Francisco. The sculpture will be comprised of a series of 37 hanging panels formed of triangular tessellations - the triangle referencing the three main departments in the building. Each panel represents a neighbourhood of San Francisco. Each seven-inch equilateral triangle represents 250 inhabitants. The size of each panel is thereby determined by the population of each neighbourhood. Additionally, the panel forms reference the topographic profile and elevation of the neighbourhoods they represent. Last, each panel will depict the green space in each neighbourhood by means of apertures where light can shine through. 

Coming together in a dynamic spherical form suspended in the lobby centre, Surface will provide unique views from the ground, second and third floors. One side of the facetted tessellations composing the undulating surface of the panels is composed of mirrored stainless steel and the opposing side is powder coated in a flat matt white finish. The visiting public contributes to the ever changing reflections of the mirrored surfaces, which echo the shifting patterns of the city. The white surfaces reflect light at a different angles to create subtle variations in tone that resemble folded paper, referencing, in part, the intellectual output of the departments that build, alter and sustain the physical terrain of the city. 

Dimensions
The sculpture will extend at its maximum 29' x 29' x 28'. There will be 37 individual panels that will hang with cables from the ceiling. The panel sizes vary from 3' x 1' (Financial District) to 12' x 6' (Mission).

Materials
The panels will be created from marine grade polished mirrored #8 stainless steel and powder coated white on the other. The hanging armature will be visually minimal, comprising stainless steel cables from the panels which will attach with anchors at the ceiling. The sculpture will require 8 psf of uniform dead load. 

Maintenance
Maintenance is minimal, as the only maintenance needs is periodic cleaning. Periodic cleaning of the piece, if desired could happen at the regular frequency of other indoor pieces in the city’s collection. Pieces will be hanging at angles that minimize the collection of debris. When cleaning, the sculpture must only be handled with clean white cotton or latex gloves. When cleaning the sculpture please use a soft dry cloth only. Do not use any liquids to clean the stainless steel panels, to avoid oxidation.

The stainless steel that will be used is marine grade and has excellent corrosion resistance. Powder coatings are extremely durable, and various types are formulated to endure the severity of chemicals, abrasion, and chipping, or UV radiation from sunlight. Powder coating is also “environmentally friendly”, with no VOC’s in any part of the powder coating process.

Cloud Cities: Stellar Stream

by Tomás Saraceno

Saraceno_1500 Mission_082817.jpgStudio Tomás Saraceno’s proposal for San Francisco Arts Commission’s ‘1500 Mission Street Public Art Project’, is an intervention informed by Tomás Saraceno’s two decade long artistic research into natural phenomena, architectural avant-garde ideas of 60’s and 70’s, and speculative thoughts on urbanism, social and environmental utopias.

Cloud Cities: Stellar Stream references Saraceno’s long-standing artistic inquiry – Cloud Cities. A venture towards airborne habitats – inhabitable modules floating nomadically through the atmosphere – harnessing the thermodynamic exchange between sun and earth and activating a common imaginary towards new ways of being within the atmosphere and on earth.

Four Clouds float up through 1500 Mission Street, growing in scale as they fragment through the central atrium, in a stream of cosmic particles. Each element is a unique geometric invention, inspired by Weaire–Phelan foam structures. These Clouds host delicate filaments, perceivable through the outer structures, interlaced in a complex system. They recall imagery of the filamentary structure of the observable universe, reminding us that we are all floating within cosmic clouds of galaxies.

All these elements inhabit the building interior, animating its architecture. The installation creates an aesthetic atmosphere rich with astronomical tropes; conceptually, the work of art makes tangible a universe of ecological entanglements - a symbiosis with air, atmosphere and earth. As the Clouds float through the building, they provide a diversity of surprising perspectives. Each viewpoint evokes a different sensation - from the ground floor visitors will be able to look up into Cloud Cities: Stellar Stream, while from the second floor visitors will feel more immersed within cloud-like structures.

This constant shift in the perception of an artwork is an important feature in Saraceno’s works, expressed in his large-scale interactive installations as In Orbit (K21, Kunstsammlung Nordrhein-Westfalen, 2013-ongoing) and Stillness in Motion – Cloud Cities (SFMOMA, San Fransisco Museum of Modern Art, 2016-2017). In these works and other iterations, the artist expands on aesthetic experience as synesthetic moment, during which one discovers the gamut and boundaries of our sensoria and perception.

This proposal for San Francisco Arts Commission’s ‘1500 Mission Street Public Art Project’ interlaces different interests, subjects and investigations that make Saraceno’s artistic practice unique: interdisciplinary and experimental. The proposed site-specific work for 1500 Mission Street conveys part of a bigger vision for a planetary future. Cloud Cities: Stellar Stream invites us to think forward and up-ward; evoking a feeling of floating through the atmosphere, with our feet on ‘Spaceship Earth’.

Maintenance
The artwork installation is easy to maintain and clean. Below there are initial guidelines on how to keep the artwork in good condition for long term. Handle the sculptures with total care. Always wear white cloth or nitrile gloves to prevent any scratches when you handle any part of the installation. Only lift the sculpture by handling the top and bottom peaks of the stainless steel rods at the intersection between the modules. The structure of the sculptures is sensitive to lever and handling actions. Please inspect the installation on a frequent basis as per instructions provided. Only present the sculptures at indoor conditions. Only present or store the sculptures in a humidity free environment and avoiding extreme variations of temperature. Don`t install or store the sculptures above or close to a heater. Control the tension of the wire for hanging. Control if the anchor and hook remain in a correct condition. Keep clear that all elements of the sculpture are in a good condition. If the sculpture becomes dusty clean it carefully with a feather duster as per provided instructions.

Ranjani Shettar - Display Board - 1500 Mission Street Lobby-V2.jpgThe 1500 Mission Lobby is a very calm, monochromatic and sophisticated interior. I propose to create a multicomponent installation that infuses a playful aesthetic dynamism into the space. The central column will be where the energy is situated and other components will appear to radiate from its center. I am considering the bridges, the reception and the mezzanines while placing components strategically. One would be able to see the artwork as a whole from a distance, but also appreciate the material, texture and colors up close from the bridges and staircases, although the components will be hung beyond reach. I want to represent energy, an essential force behind everything living and nonliving that is holding the world together. The central column is inspired by the structure of DNA, the building block for life that links all living forms. The artwork represents the energy of the building, with its open architectural spaces, multipurpose functions and the diversity of people working and passing through, as an animated, positive force to create and sustain a civic organization. 

The installation will be composed of multiple suspended components.  The central spiral will be 33 feet high, 5.5 feet wide and weigh approximately 45lbs. The other components will range in size from 4 to 6 feet across and weigh from 4 to 7 pounds. 

Materials
304 grade Stainless Steel
Muslin fabric
Tamarind seed powder paste 
Acrylic colors
Paraloid B72
Kevlar / Aramid thread 

Suspension System
The components are all suspended from the ceiling using hooks and Kevlar/Aramid thread. The suspension mechanism will have negligible aesthetic impact and the components will seem to just float in space. The threads are thin and barely visible but strong for components that occupy volume and seem to suggest weight but are light. 

Maintenance
The surface of the work can be wiped clean with a soft cloth when any dust has accumulated.

By Sarah Sze

Sarah Sze 1500 Mission Street_082917.jpgFor the new 1500 Mission Street Atrium lobby, Sarah Sze will create a site-specific aerial sculpture that will occupy and activate the building’s atrium. Emerging from the architecture of the atrium the work will spin down 
from the ceiling with a centrifugal force as if it were a swirling metropolis. Gestures emanating from the upper reaches of the space will flow dynamically down towards the central lobby of the building as if drawn by natural forces or air currents. As the piece cascades downward it will multiply and develop into a complex floating city of objects and structures. Expanding outward exponentially it will create an immersive world with an altered sense of gravity, scale and time. Energetic and complex, the sculpture will seem caught in a state of growth and flux. As visitors approach the sculpture it will immerse them in a micro scale at its interior, while simultaneously gesturing to a macro scale as it advances over the larger space of the atrium. 

Traversing across the space the work will emphasize the powerful architectural expansion, compression and release of the atrium. The work will also highlight the space’s potential for public interaction and movement, signaling the lightness of the building and acting as a magnet
 to draw viewers from all sides of the atrium. The installation will harness the natural light sweeping through the space emphasizing the building’s openness. 

The work will be fabricated in steel and finished with industrial UV resistant architectural powder coating for long-term durability. The gray and metallic powder coatings will mimic the color palette and elemental character of the buildings materials creating a harmony with the architecture of the atrium. The gradating tonal color scheme will give the sculpture the appearance that is a drawing materialized and floating in space.

As with all Sarah’s work, the sculpture will be site-specific and emerging from the architecture. The final form and details of the work will develop through the design phase intimately relating them to the site of the sculpture and connecting to the buildings functions as a place of design, planning and collaboration between the government and the public. The work will take into account the atrium’s myriad contexts to embody a spirit of simplicity, airiness, and the spiraling movement of progress.

Technical Specifications

The sculpture will be approximately 30’ H x 35’ L x 17’ W. It will be fabricated in steel and finished with industrial UV resistant architectural powder coating. The powder coatings will be a series of gray and metallic colors. The total weight will be approximately 1,500 LBS. The work will be hung from a series of attachments to the ceiling structure above, including a combination of 1/4 Inch steel all thread hangers sleeved with a 1/2 inch diameter tube, 3/8 Inch steel all thread hangers sleeved with a 5/8 inch diameter tube, and stranded wire cables. All attachments will be in accordance with the existing engineering and construction of the building. 

Maintenance
The sculpture will require very little maintenance. It will be constructed of high quality materials selected for their strength and durability. The sculpture will be resistant to rust, discoloration and graffiti. It will not require frequent cleanings or repainting. The work should be dusted with compressed air every 3 years. This can be achieved by using a mechanical lift and air compressor.
