Architecture: |
The
bold architectural statement from Diller & Scofidio along with a
dramatic waterfront location entwine to produce a vibrant, high tech
center for thought provoking showcase space, performances, and instructive
activities. The Institute of Contemporary Art anticipates developing and
displaying a diverse permanent collection of art comprised in various
media formats which has acted as the driving catalyst for the architectural
program. The ICA anticipates
receiving individual works and complete traveling exhibitions to be
displayed in the new building including sculpture, paintings, and drawings.
Video and projection pieces may be shown, either as interpretive
material accompanying a show, or as art pieces in their own right.
Viewing
these works of art in natural daylight was a prime objective of the
institution and consequently influenced many of the architectural components
comprising the new Institute of Contemporary Art.
North facing skylights will facilitate natural light throughout
the building’s main gallery halls which will be located on the 4th
floor. Flexibility was
key in designing the interior program.
Lighting systems were designed to respond effectively and economically
as layouts and displays are changed and also to protect artwork from
being damaged or faded by exposure to ultraviolet light.
The ICA will be graced with an array of lights, illuminating
a “floating box” and radiating a warm, welcoming waterfront persona.
Numerous architectural explorations eventually led to a design surprisingly sensible and straightforward: a steel-frame box building with a column-free 4th level that will radically cantilever out over Boston’s harbor. The cantilevered design embraces a public harbor walk and produces ever-changing panoramic spectacles of the water's edge. Collaboration between architect and engineer early in the design process resulted in a highly efficient structure in which structural elements have been fused to create architecture. This planning will result in a 65,000 ft2 building which appears to float above land and sea. |

Zoning and Historical Information |
Design
and construction of a new museum in Boston is an uncommon incidence
and opportunity. The new
building for the ICA will be the first art museum to be built in Boston
in almost 100 years and is destined to embody the architectural potentials
of the nations most historic cities.
In that milieu, it is anticipated that the design creates a pioneering
breakthrough museum for art of the 21st century.
The
planners and designers envisioned an affordable structure with a striking
profile, situated on a small lot atop a reclaimed landfill on the shore
of Boston Harbor—one that would incorporate the harbor’s shoreline walkway
into the ground floor while boasting a contiguous gallery above.
With structural and architectural challenges closely intertwined,
the project’s architects at New York-based Diller + Scofidio invited
engineers from Arup New York to participate early on in the conceptional
phase. Fan
Pier, at 13 million square feet, makes it the largest proposed private
development project on the Southern Boston Waterfront.
The land is owned by the Chicago-based Pritzker family and is
inherently a key piece of Boston's industrial land.
The Institute of Contemporary Art is just one of nine buildings
proposed to be built along this waterfront land.
In order to obtain the proper permits, developer Spaulding &
Slye agreed to construct parks, water transportation, and other publicly
accessible buildings during the first stages of the Fan Pier development. These public amenities, including the Institute of Contemporary
Art, must be completed early in what could be a decade or more of phased
construction. A
height limitation of 70 feet was imposed early on in the design of the
ICA building in order to escape the title and classification of a high
rise. This effort was achieved
so that additional codes and regulations could be avoided. |
Building Envelope | The exterior envelope of the new Institute of Contemporary Art is composed of identically sized vertical planes of transparent glass, translucent glass, and opaque metal. The use of transparent glass facilitates a natural daylight viewing area while the use of opaque metal responds to the functional requirements of the interior plan. These elements obscure the division between windows, walls, and doors while at the same time giving an impenetrable, seamless, and taught skin capable of protecting cherished contents from climatic conditions along Boston’s coastline. Along the North side of the 4th floor exhibition space spans a lenticular glass curtain wall, which is composed of minute vertical lenses. These lenses eliminate glare by blocking all light except that which is viewed perpendicular to the surface. The theater, located on the second and third floor, boasts a full complement of clear glass glazing which frames a dramatic backdrop with a harbor view. These walls respond to strict performance needs by translating from filtered luminosity with no panoramic view to complete blackout. Four massive trusses-made from welded W section beams-grace the exterior through a silhouetted appearance behind the main gallery’s translucent facade. Extensive overhang details due to the cantilever of the structure facilitate the building envelope to run beneath the building as well as on top. The roof is composed of flat EDPM with an extensive assortment of north facing skylights while the underside is made up of wood that mirrors the harbor walkway. Overall, the envelope of the new Institute of Contemporary Art has been carefully designed to produce a welcoming and dramatic waterfront presence. |
PART 2: BUILDING STATISTCS |
Electrical: |
A single 480V, three phase, 4 wire service will be provided by the local Electrical Utility Company to power the building. The transformer is mounted outside at grade on a pad. A “Standard Service” type of 2500 amps @ 480V, 3 phase is provided. | |
Electrical Service | |
Emergency Generator | Generator
Loads: |
Fire Alarm System | The fire alarm system is fully addressable and designed for ordinary and light hazard classification of building. The Staff Entry holds a fire command station, remote annunciation panel, controls for air handling equipment, and smoke control/purge. Fire alarm annunciation will be via voice alarm in all program areas assessed as at risk including art display, art storage, mechanical/electrical rooms, elevator shafts and machine rooms. |
System Redundancy | A second contingency feeder is provided by Utility so that a failure of any single utility network feeder will not interrupt power to the building. A single fault tolerance at the point of connection to the building will provide for additional redundancy. Emergency power is distributed independently of normal power system raceways. UPS power via distributed local units are applied to essential building systems. |
The
lighting scheme addresses the following key requirements: |
|
Artwork Conservation | • Level of illumination • Period of time over which artwork is exposed to illumination • Spectral content of light including ultraviolet |
Non-Public Areas | Non-public areas are predominately lighted through high efficiency, fluorescent fixtures with occupancy sensors where additional energy savings can be realized. Mechanical/electrical rooms, stairways, and corridors are designed at 20 foot-candles and serviced with pendant mounted industrial type 4-feet fixtures while utility rooms and office break rooms are set at 30 foot-candles. Lamps possess the following characteristics: rapid start, T-8 fluorescent, electronic ballast, high power factor, and a color temperature of 3500k. Self-powered LED exit lights are included. |
Gallery Design | A balance between increased illumination for easier viewing and conservation of artwork by limiting exposure to light is a primary focus for lighting of the 4th floor galleries. Fixtures were selected based on color temperature and color rendering properties of the light sources. For all display spaces, fixtures with a color-rendering index of 90 or greater are specified. All surfaces in the Gallery are finished with a neutral matte, white color. Lighting fixtures were also chosen with respect to their uniformity of illumination. Directional lights, via track lighting, are positioned to produce lighting angles of between 25-40 degrees from the art at eyelevel in order to reduce glare. A bus track is included with anticipation of supporting greater lighting loads, power taps, and small hanging loads. The Gallery floor is kept low to avoid bright reflections of the floor in some artworks. Diffusing layers on the inside of windows and illumination of building exteriors combine to minimize distracting reflections of the interior. Sub-division of the galleries through the use of walls and display cases has been accounted for in the lighting plan. All light sources in display spaces have a low direct heat radiation factor to avoid damage from excess heat. Linear fluorescent fixtures are fitted with Filter-Ray acrylic UV filters while track lighting are fitted with Optivex glass UV filters. Direct sunlight has been minimized through a diffusing ceiling material and north-facing skylights. |
Daylight Design | Daylight is used
to provide ambient background light because of the following reasons: • Good color rendering because of more compete color spectrum • Energy savings • Contact with the external environment gives an awareness of the external environment and time of day. The
daylight delivery system consists of a series of horizontal north-facing
skylights. The advantage of this system are that changes in direct solar
radiation on the roof are dampened out. The skylights include a perforated
reflector that improves ceiling luminance uniformity by reducing light
towards the south and increasing light toward the north. The 4th floor
galleries have translucent ceilings made up of specially formulated
fabric. This fabric is 100% Trivera CS and white in color producing
a visible light transmission of at least 70%. Mechanical blackout shades,
linked with the building control system, provide for the optimum amount
of light passing through the skylight system. |
Long Gallery (North Facing) | Along the north side of the building runs a long gallery in which light levels will exceed recommendations for art conservation. To minimize this negative effect, the glass is composed of an angular cut-off film and a UV blocking PVB interlayer. In addition, motorized black out shades are utilized to mitigate direct solar radiation on the glazing until 10:30AM. |
Temporary Art Storage | There are no rooms
for primary storage of art on the premises of the new Institute of Contemporary
Art. However, temporary art storage facilities have been justified into
the interior plan and are accounted for in the lighting design. The design
includes the following parameters: • Ultraviolet protected luminaries • 500 lux/50 foot candle are provided for temporary viewing of specific artwork for removal. • Lighting turned off automatically when facilities are not in use |
Main Lobby | Spaces are sensitively lit with approximately 200 lux / 20 foot-candle to allow for easy visual transition between spaces. Linear fluorescent luminaries with an opal glass covering and an integral adjustable tungsten halogen downlight provide for lower level lighting. In addition, round adjustable in-grade uplights along the glass and wall illuminate the lobby ceiling. The lighting controls are located next to the security office ticketing desk. |
Theater | The peak demand load for the theater is assumed at 288 Kw. It has been designed with a diverse range of activities from lectures to performances. The architectural lighting in the Theatre responds to the outside through extensive use of glazing. Minimizing glare was of prime concern to the designers involved. Approximately 150 lux / 15 foot-candle of light on the floor is provided for occupants to find their seats. While viewing a presentation or performance, 30 lux / 4 foot-candle of light is given minimizing spill light upon projection screens. To be consistent with exterior lighting conditions, the theater ceiling is up lit using asymmetrical floodlights mounted to a pipe grid. Square downlights recessed into the ceiling provide for additional illumination. |
Dinning Room | The dinning room is coded as a light refreshment service facility to avoid extra code requirements associated with a destination restaurant. Direct sunlight is avoided while producing average lighting levels of 200 lux / 20 foot-candle. Adjustable tungsten downlights are used to accomplish this criteria. |
Office Areas | Indirect pendant fixtures provide 30 foot-candle on working surfaces. Direct task lamps provide additional luminance. |
Emergency / Security Lighting | Emergency lighting is not illuminated during normal gallery opening hours. Security lighting maintained during off-peak times throws less than 5 lux / .5 foot-candle. Emergency lighting is comprised of 2 foot nominal linear T5HO fluorescent incorporated into the gallery ceiling track system. Emergency luminaries are circuited to the emergency generator as well as having battery backup capability. |
Mechanical: |
Cooling System | Two (2) chillers operating in parallel and located on the center spine roof cool the Institute of Contemporary Art. The total estimated chiller load is 280 tons while each chiller is sized for 140 tons or 50% of the total cooling capacity. Chillers are acoustically lined to meet strict noise mitigation criteria. The chilled water is a 35% mixture of propylene glycol and is supplied to the building at 45°F and returned to the chiller at 55°F. Two (2) variable volume pumps sized at 830 GPM distribute chilled water throughout the building. |
Heating System | Two (2) gas-fired low temperature hot water boilers located at the 4th floor Mezzanine Mechanical Engineering Room provide building heating. Each boiler is sized for an output capacity of 1500 MBH and comprises 70% of design heating load. Low temperature hot water is distributed to perimeter finned tube radiation. Heating hot water will be circulated using a primary-secondary pumping system with temperature reset based upon outside dry bulb temperature. Variable volume secondary pumps are powered via variable speed drives. The heating hot water is supplied to the building at 180°F and returned to the boilers at 160°F. Two port modulating control valves are provided at all terminal devices including air-handling units heating coils, fan coil units, and hot water unit heaters. Heating hot water will also flow through hot water coils and preheat outside air being supplied for ventilation through the air-handling units. |
Humidification System | Stringent humidification is required in all the permanent and temporary galleries. Moisture, in the form of steam, is added to the air stream to achieve the required humidity level. Two (2) natural gas fired steam generators located in the Mezzanine Mechanical Engineering Room will generate this steam. The first steam generator is rated at 138 lb/hr while the second is rated at 345 lb/hr. Two (2) such generators are used to provide low load control and a measure of system security. Stainless steel will comprise the steam supply and condensate return piping. The two (2) air-handling units serving Gallery spaces are equipped with a direct steam dispersion grid and control valves. All four (4) air-handling units have dedicated humidification sections built into them. |
Air Handling Systems | The Institute of
Contemporary Art is divided into five (5) major zones. Zone 1: Permanent Gallery and North Gallery (half of the space) on 4th floor Served by a 21,140 CFM constant air volume air-handling unit (AHU-1) located on the Center Spine Roof. The unit includes particulate filters, preheat, reheat and cooling coils, humidifiers, supply, and return fans. Airside economizer is used to allow energy conservation during non-peak outdoor conditions. Zone 2: Temporary Gallery and North Gallery (half of the space) on 4th floor Served by a 20,800 CFM constant air volume air-handling unit (AHU-2) located on the Center Spine Roof. The unit includes particulate filters, preheat, reheat and cooling coils, humidifiers, supply, and return fans. Airside economizer is used to allow energy conservation during non-peak outdoor conditions. Zone 3: Lobby, Retail, Administration, and Dining Room on 1st, 2nd, and 3rd floors Served by a 31,500 CFM variable air volume air-handling unit (AHU-3) located on the Center Spine Roof. Air is distributed to different zones through variable air volume boxes, which vary the amount of air supplied to each zone based upon its cooling or heating needs. The unit includes particulate filters, preheat, reheat and cooling coils, humidifiers, supply, and return fans. Airside economizer is used to allow energy conservation during non-peak outdoor conditions. Zone 4: Theater on 2nd and 3rd floors Served by a 22,500 CFM constant air volume air-handling unit (AHU-4) located on the Center Spine Roof. The unit includes particulate filters, preheat, reheat and cooling coils, humidifiers, supply, and return fans. Airside economizer is used to allow energy conservation during non-peak outdoor conditions. Zone 5: Mediatheque on 4th floors |
Plumbing | Domestic water system is brought into the Utility room (southeast portion of the building) through the municipal water main. The point of entry is greeted with a water meter. A duplex booster pump package is used to pressurize the building system. A gas fired water heater located at mezzanine level maintains water at 110°F. This hot water system is equipped with re-circulation pumps. The storm drainage system is designed based on a 100 year storm at an intensity of 4 inches per hour. The sanitary drainage system is designed to maintain at least a 1% slope per foot and 2 cubic feet per second velocity on the system. |
Structural: |
Foundation | All loads are resolved into deep driven piles at ground level. These piles are comprised up of 11,000 linear feet of 215-ton H-section bearing piles and rely solely on soil friction to carry the building’s load. Due to the corrosive properties found at the site, a corrosion epoxy is applied to the piles up to 60 feet deep. An impressed current cathodic protection system has also been implemented to prevent corrosion. Ground beams are supported at pile cap locations. Ground Slabs are designed as suspended slabs spanning across ground beams allowing for settling of the soil beneath them over time. |
Cantilever | The Institute of Contemporary Art has a striking fourth level cantilever that demands attention. The 84-foot cantilever achieved with the utilization of four mega-trusses (25ft depth) with a 96 foot back-span. The trusses are each supported by two mega-columns. |
Roof | A lightweight triangular truss roof allows for both the dispersion of daylight as well as the distribution system for the MEP services. North-facing skylights create a 6ft wide void in the roof system. |
Gallery | Gallery space load is distributed by eight mega-columns positioned at the south edge of each truss and 96 feet in along the back span. Below the gallery the interior program divides in two halves by a central core strip of elevators and stairways. The east side utilizes typical structural composite steel framing. |
Theater | On the west side of the structure is an inclined theater, with steps from grade level to the second floor on the exterior of the building, a flat stage area on the second floor, and inclined seating from the second to the third floor. The theater is supported, along the West, by cable hangers suspended from the western mega-truss, creating a column-free lobby below the theater. The lobby is framed with ground slab and grade beams. Columns for supporting the inside of the theater are located along the east edge of the ground floor lobby and extend up to the stage and inclined seating. The floor systems of the theater, 2nd, and 3rd floors are comprised of composite steel deck. |
Construction: |
Fire Protection: |
General | The building is fully sprinklered with wet type sprinkler heads protecting all building areas. The gallery spaces present an interesting fire protection application as the ceiling is composed of a combustible material and equipped with the concealed type sprinkler heads in the ceiling as well as pendent sprinklers above the ceilings. This creates a double layer of heads necessitated by the existence of large skylight depths. The building is predominately light hazard with some areas considered by NFPA13 as ordinary hazard. Areas of light hazard are protected with standard type quick response sprinkler heads while areas of ordinary hazard are protected with standard response heads. The system includes Siamese, two class II fire standpipes and one combined standpipe/sprinkler risers. The building is below the high-rise level of 75 feet and thus minimum pressure requirements were reduced. Hydrant flow tests revealed a static pressure @ 67 PSI, residual pressure @ 62 PSI, and a flow of 868 GPM. |
Atrium Smoke Management Philosophy | The Institute of
Contemporary Art consists of an atrium approximately 60 feet high and
thus must meet special requirements for this kind of space. Smoke extraction
is taken through the architectural roof of the atrium via ductwork and
three (3) 52,000 CFM roof-mounted fans. These fans are powered from the
emergency generator and will be activated by smoke detectors automatically
in the event of a fire. Makeup air is provided at the bottom of the atrium
utilizing two strategies: • By automatically opening windows on the southern façade of the lobby • By automatically opening the doors in the dining room of the restaurant • By reversing return fan motors so they operate like supply fans |
Transportation: |
Vertical Transportation | Two geared passenger elevators meet the vertical transportation demands of the Institute of Contemporary Art. A public elevator with dimensions of 18’X10’ and a net lifting capacity of greater than 20,000 lbs runs from the lobby up to the 4th floor gallery. Its speed is rated at 150 feet/min. A staff elevator with dimensions of 7’X6’ and a net lifting capacity of greater than 3,500 lbs runs also runs from the lobby up to the 4th floor gallery. Its speed is rated at 350 feet/min. The total height traveled by these two elevators is 45’-6”. A 750 pound capacity combination wheelchair lift and collapsing stair is located at the projection booth. |
Outside walkways | A large cantilever off the northern side of the building embraces a public harbor walkway. This wooden walkway flirts with the waters edge while providing access to both the north and west side of the Institute of Contemporary Art. Walkways along the Eastern and Southern exposures are standard poured concrete and connect to provide 360 degrees of free movement around the outside of the building. Emergency vehicles may access these sidewalks during an emergency by a gate set on the Southeast corner of the building. |
Parking | A 200-space parking lot is provided just South of the building. Access to the building is through a 1st floor atrium directly off of the parking lot. Patrons can be dropped off via a loading and unloading area next to the main entrance. In addition, goods and services are supplied via a loading dock along the Eastern side of the building. |

Programming | The building houses a 300-seat theater and related support spaces which will play an important role in making the Institute of Contemporary Art a success for the many people who will use it. Acoustic design takes into account a wide variety of programming including film, video, jazz, new music, dance, lectures, symposia, and theater. Adjustable acoustically absorptive elements have been incorporated to lower the reverberation times and attenuate unwanted sound reflections from the glass and other wall surfaces. | |
Room Volume / Shape / Surface Treatment | The main uses of the theater necessitates room acoustics that are fairly ‘dry’ constituting a low design reverberation time of between 0.8 to 1.4 seconds at mid frequencies. High levels of speech intelligibility for the audience results. Glass coving house-left and upstage posed challenges for controlling unwanted reflections. Absorptive material with thicknesses of two to four inches are distributed on the ceiling and rear walls of the theater to achieve desired reverberation times. Music events requiring sound control have been accommodated through the use of small, portable acoustic shell/screen elements that promote the transfer of sound energy from the stage into the audience. A series of acoustical reflectors have been placed over the stage and front row seating areas to enhance onstage hearing. Concrete flooring has been implemented as a hard reflective surface in the audience while the stage floor is comprised of resilient wood construction. A series of roll-up banners along the side walls allow for additional control of reverberation time, acoustic reflections, and sound energy density. | |
Noise Issues | The site is impacted by a number of unwanted environmental noise sources including vehicular traffic, watercraft, and air traffic. Special attention has been paid to acoustical separation between adjacent spaces and noise making equipment in the facility, and to isolate outside environmental noise. The exterior wall consists of a double-glazed partition system (3/4 inch thick laminated inner layer with ½ inch laminated outer layer) in an attempt to avoid resonances frequently encountered with single-glazed systems. Sound and light locks with sound absorbing finishes and gasketed doors have been implemented at all theater openings. The roof consists of 8 inch thick concrete roof deck over entire seating area and stage. | |

includes occupancy sensors, programmable time clocks, photocell sensors,
relay control panels, and dimmer panels. Further separate lighting controls
are provided for gallery display lighting system, lobby, ground floor
public spaces, and boardroom, theatrical, and auditorium lighting.
Blackout shades for the 4th floor naturally lighted environment are also controlled by the building automation system. The blackout shades are programmed to block daylight during hours that the galleries are closed including early morning and late evening. Lowering or raising the shades makes seasonal adjustment. This system protects artwork from summer overexposure and allows work to be fully illuminated during winter. Lighting levels can be adjusted in specific parts of the gallery by controlling individual shades or by controlling a grouping configuration. Easy control of the electric lighting control zone is via programmable control switching panels. Two programming jacks are located in each of the East and West Galleries. A laptop personal computer can be plugged into the system’s jacks. |
