These large carved slabs are covered with muscular, stately, and fantastic figures adorned with hats, earrings and amulets. As they process across our gallery in sandals, they carry small bags, and many have both weapons and jewels.  Cuneiform writing covers sections of their bodies in lacy overlay.

The room in which they are housed had, until recently, stairs at both the east and west entries, which lead to the Beaux-Arts Court and West Wing elevator, respectively.  A lift on the west side, and a stair-crawler, on the east side were installed to provide access to people with disabilities, but these machines cluttered the room, had operational problems, and were inconvenient to use. When the Museum received a grant from New York State to address access on the third floor for people with disabilities, an opportunity arose to finally do something about the steps.

Initially, it was hoped that short ramps might solve the problem, and various configurations were explored. According to the American with Disabilities Act, a ramp must be no more than 8% in slope – meaning that for each rise of 1″, the ramp must be 1 foot long. All the ramps we designed seemed much too intrusive in the narrow room. Finally it was understood that actually sloping the entire floor would be less disruptive than building ramps, and actually this type of construction would not be considered a ramp by the Building Department, as the slope would actually be less than an 8% ramp when tilting the floor over such a long distance.

Our strategy had the advantage of allowing the reliefs to be kept in their original installation locations.  Before any work began, the reliefs were protected in place.

The new ramps, extending from each of the end entries, were built on top of the existing floor with minimal demolition. As terrazzo is a material found throughout the building, it was chosen for the ramps. They were poured over a concrete structure, and ground down to their final finish.  A protective rail was anchored into the ramp, and the room was updated with new lighting, signage, and other graphic material.

The resulting gallery has solved a number of problems at once, and has reinvigorated these fascinating men and genies.

The project team consisted of Brooklyn Museum’s Planning, Conservation, Collection and Design Departments, Polshek Partnership Architects, Gilbane Building Company, and EW Howell, General Contractors. The floor was executed by Port Morris Tile and Marble.

Beaux-Arts Court Gets a New Floor /2008/07/09/beaux-arts-court-gets-a-new-floor/ Wed, 09 Jul 2008 12:29:28 +0000 /bloggers/2008/07/09/beaux-arts-court-gets-a-new-floor/ plan2.jpg

Postcard of the plan for the Brooklyn Museum as envisioned by McKim, Mead, & White in 1893.

The original design plan for the Brooklyn Museum, developed by McKim, Mead, & White in 1893, called for a building of about 500 feet long on each side. The Museum was planned to be 3 times as large, with four courts proposed each about 150 feet square to be roofed with glass. Only one of these quadrants was actually built and it now is the Museum’s prime public indoor space, and the site of the dance parties at our famous Target First Saturdays.

If you’ve been in the building lately, the noise heard all around the eastern part of the museum is the result of our project to create a new glass floor in our third floor Court. The 10,000 square foot glass block floor in the Court has been deteriorating for many years. The glass tile and reinforced concrete panels are only 1 ¼” thick, and this unusually light structure was achieved by custom fabricating panels so that the concrete works integrally with the glass to create a stiff membrane. Over the course of 80 years many glass blocks have broken through use. Repairing the number of cracked blocks that are now there is no longer practical, so a new approach was needed to solve the problem. With support from the State of New York, the Museum was able to create a solution that would be durable, long lasting, and appropriate to the space.

Court currently under construction.

In order to create a floor that was in the spirit of the original design, we decided to preserve the existing glass tile, terrazzo, and marble mosaic tile and construct a new floor 4-1/2” above it, aligning with the level of the first tread in the steps at the four corners of the space. The new floor is made of laminated glass panels each the size of the original pre-cast concrete panels, supported on steel frames. The areas that were terrazzo will be replaced with new terrazzo to match the original. In order to make sure the floor will look the way we wanted we did a mockup, which satisfied our requirements.

Glass floors are a relatively new idea, and only possible because of advances in glass technology that have been rapid in the last decades. The glass is actually a three layer “club sandwich,” about 2” thick, that supports as much load as the building code requires. It has a special slip resistant coating, and small bumps to make it easy to walk over. Between the layers are films that prevent the transmission of ultraviolet rays that could be damaging to art installed on the floor below in our Hall of Americas.

court2.jpg

In the Court, the original floor panels will be obscured but still slightly visible through the new glass. This approach allows a person to see the old floor through the new one – an effect that should be quite interesting. When the new floor is completed the plastic panels in the ceiling of the Hall of the Americas below can be removed, restoring its original deeply coffered appearance with the underside of the original glass tiles exposed. Mockups indicate that from the Hall of the Americas, the view to the original glass blocks will be essentially unchanged and the amount of light transmitted will not be noticeably reduced.

In addition to the new floor, we are installing new sprinklers, a new ramp both for improved access, and the nearby bathrooms will be upgraded. After the Court opens there will be a new catering kitchen to service events in the space. Right now the contractors are finishing installing the frames and making the setting bed for the terrazzo panels. The next step will be to install the terrazzo and new glass panels which are being fabricated off site, then the court will reopen to the dance party at the October Target First Saturday.

Newly on View: Herald Tribune Owls /2007/12/14/newly-on-view-herald-tribune-owls/ /2007/12/14/newly-on-view-herald-tribune-owls/#comments Fri, 14 Dec 2007 14:50:59 +0000 /bloggers/2007/12/14/newly-on-view-herald-tribune-owls/ The next time you enter the Grand Lobby of the museum, make sure you cast your eyes upwards. In one of the openings in the old brick façade you will find two newly on view objects. They are a Pair of Bronze Owls, two of twenty-two, which originally stood along the roof line of the old Herald Tribune building when it was built in 1893. At that time the owls eyes were electrified, blinking on and off. The owls were created by sculptor Antonin Jean Paul Carles. When the building was torn down in the 1920’s, the owls, Minerva and the Bell Ringers were given to NYU. The latter two sculptures and two owls with outstretched wings were loaned to the city in 1940 for display in Herald Square, where they remain today. The two owls that entered the Brooklyn Museum in 1971 are also on long-term loan from NYU.

To prepare for installation, the owls were first cleaned with a soft brush and vacuum to remove surface dust and then with a detergent and water to remove the more tenacious grime.

Pictured above is Emy Kim, fourth year conservation intern from the NYU IFA Conservation Program, rinsing the owls.

Before the owls were placed into the brickwork they were secured to a mounting board for safe transport and installation. Since the owls weigh in at 251 and 232 pounds they had to first be rigged onto their respect mounting boards. Soldered brass mounts were then created to secure the owls to the boards.

Pictured below at left are Paul Daniel, mount maker, and Jakki Godfrey, project conservator, rigging one of the owls onto a mounting board. Pictured below at right is a detail image of the mounting system.

Finally it was time to install the owls. The mounted owls were secured to a forklift and then gently lifted to their new location. Once in position the owls were secured in place to the brickwork.

New addition /2007/12/06/new-addition/ /2007/12/06/new-addition/#comments Thu, 06 Dec 2007 13:59:24 +0000 /bloggers/2007/12/06/new-addition/ People approaching the Museum from the Parking lot or Washington Avenue may have noticed construction materials and machinery behind a green fence. The Museum is building a new addition which will provide space for art delivery, packing, and crating. Once the building is complete, it will be relatively discreet, as it was designed to be ‘nestled’ into the hill.

trench.jpg

There are a number of activities going on right now. First, trenching is being done for new electrical service to the building. The new electrical lines will run underground in the street from Eastern Parkway, then down Washington, and across our parking lot, and into the building. Once the trench is complete, electrical and phone lines will be placed in the hole. As might be expected, we discovered some large rocks, or boulders along the way. One very large one took about a week to remove. The technique used was to drill many holes into it and shatter it, remove the pieces, and do this repeatedly until completed.

tree.jpg

Next, excavation will begin on the east side of the building, so that foundations can be poured for a new two story building. There are a number of large old trees near the building site. In order to help one of them survive, we air spaded the roots. This is a process of exposing the roots using air, not shovels, so they are not damaged. Because no large roots had to be cut where large trees cross the construction area, the tree will survive.

Having this addition will give us a dedicated art loading dock for the Museum, so that sandwiches, paper, and the myriad of other things delivered to the Museum are separate from the art! The building will also house mechanical equipment that will enable the eastern section of the museum to be air conditioned. As some people know, our building was built in stages, starting in 1897. At that time air conditioning was not considered essential for museums. Today, both to keep the environment stable for art and visitors, not only temperature control, but also control of humidity is considered ideal for art. We will have had, and will continue to have quite a few projects that are leading us to full climate control for our collections.

Up Close and Personal – Statues and Their Meaning /2007/10/24/up-close-and-personal-statues-and-their-meaning/ /2007/10/24/up-close-and-personal-statues-and-their-meaning/#comments Wed, 24 Oct 2007 15:42:21 +0000 /bloggers/2007/10/24/up-close-and-personal-%e2%80%93-statues-and-their-meaning/ CONS.09.937.1_.30DT_det27_1.JPG

The first time I came across the statues that sit along the top of the building was when I digitized images of the Museum’s exterior as an intern in the Archives. It was great to see some of the early images of the building and to see how it developed and changed over the years. The statues are part of our Museum’s history and a frequently asked research topic at the Libraries and Archives. When I was thinking about this post, I was curious to see what types of questions we’ve received in the past, so I took a look at some of our old reference request forms. Yes, in typical archives fashion we keep these forms and they can be very useful, such as in this situation. The questions about the statues include inquiries about specific sculptors, the meaning of the statues, who created them, and when and how they were made. Here’s a little background information on the creation of the statues.

statues_names.jpg

McKim, Mead & White, the architects of the Museum, included the statues as part of the Museum’s original design. The statues and the unrelated names inscribed below them were meant to represent notable aspects in the history of civilization. The statues in particular were symbolic and not intended to be portraits. This is visually reinforced by the fact that the statues and the names are not aligned, but staggered (see photo above).

The noted sculptor Daniel Chester French was given the responsibility of creating thirty statues of allegorical figures representing Persian, Indian, Chinese, Japanese, Hebrew, Greek and Roman subjects. He enlisted a group of highly-regarded sculptors to assist him with the project (Edmund T. Quinn, Attilio Piccirili, Edward C. Potter, Karl Bitter, Janet Scudder, Augustus Lukeman, Charles Keck, George T. Brewster, Kenyon Cox, Herbert Adams, John Gelert, and Charles A. Heber). The finished statues were installed in 1909.

Because of the continuing interest in the statues, we thought it might be a good idea to put together some images and information on them. This was a group effort which included various departments (Information Systems, Digital Collections and Services, Conservation, Planning and Libraries and Archives). See below for additional images and resources. Hope you enjoy them.

Façade

  • On the East façade (Washington Avenue), there are statues representing Persian Religion, The Indian Law Giver, Indian Literature, Indian Philosophy, and Indian Religion.
  • The North façade (Eastern Parkway) features Chinese Religion, Chinese Philosophy, Chinese Art, Chinese Law, Japanese Art, The Hebrew Law Giver, The Hebrew Psalmist, The Hebrew Prophet, The Hebrew Apostle, The Genius of Islam, The Greek Epic, Greek Lyric Poetry, The Greek Drama, The Greek Statesman, Greek Science, Greek Religion, Greek Philosophy, Greek Architecture, Greek Sculpture, and Greek Letters.
  • The West façade shows Roman Law, the Roman Statesman, the Roman Emperor, the Roman Orator, and the Roman Epic.

Photos

These photos were taken by our Conservation team in 2001 just prior to the construction of our new entrance. The initial phase of the ambitious construction project called for the restoration of the entire Eastern Parkway façade of the building, which included the cleaning and re-pointing of all the limestone and granite. With scaffolding in place, the Museum’s conservation staff took advantage of a rare opportunity to survey the thirty large-scale statues on the Museum’s cornice and make necessary repairs.

Further information on the statues can also be found in the Museum’s Library, which is open to the public Wednesday through Friday from 10:00 to 12:00 and 1:00 to 4:30.
