    Harlem Hospital Center Modernization

    But there are many creative and meaningful ways to use glass to make a statement and honor legacies in architecture.

    One extraordinary example is Harlem Hospital Center which is a bed, public teaching hospital affiliated with Columbia University. The hospital was established to provide healthcare to the citizens of the neighborhood. With the wave of the African Americans who moved to New York after the World War, the hospital soon outgrew its initial building.

    After acquiring land, a new building opened on April 13, The hospital developed a teaching program that is affiliated with Columbia University, and has continued to serve the Harlem neighborhood since its inception.

    Just as technology and healthcare have progressed through the years, so has innovation in construction — especially using glass to make a statement and not just a unique building material.

    The modernization and creative use of glass made the Harlem Hospital Center the new front door to Harlem. Soaring 65 feet high and spanning a city block, the colorful, 12,square-foot glass facade mural depicts excerpts from the story of the African diaspora, creating a dramatic frontispiece along Lenox Avenue for the circa Harlem institution.

    Using glass in art is nothing particularly new, but when a design incorporates custom printed glass frit patterns with building facades to make a breath-taking impression, it makes a grand statement.

    The Harlem Hospital Center in New York City is a great example of the kind of large scale, structurally-glazed curtain wall project that uses digitally-printed fritted silk-screened glass to create an impressive work of art. The effect is heightened at night when the entire facade is backlit by the interior of the building. The artwork is the focal point for the patient pavilion, providing a visual history for generations to come. We install all of our work with our own dedicated union labor force.

    The new home for the Columbia Business School is based on an exchange of ideas and social interactions in different settings formal and informal combined with advanced technology. Student engagement with the surrounding neighborhood is also a fundamental component with each classroom having view to the exterior neighborhood and landscape.

    To say the new buildings are conspicuous would be an understatement. The buildings honor that generosity by naming the twin structures The Ronald O.

    Kravis Building. The new facilities will host graduate-level schools and research centers. Perelman and Kravis are not the only familiar names that will be attached to the project as the endeavor is a large collaboration of some of the best people and firms in the industry. While obvious by the modern appearance in the renderings, the project is not about typical bricks and mortar. There is actually an underlying theme about transforming the School, business education, and the nature of business itself through both buildings integrated flows and expressions of form.

    The school tapped Turner Construction as the construction manager but needed a trusted, specialized partner when it came to the sophisticated design and techniques for constructing the primarily glass outer appearance.

    Both of these new structures at Columbia Business School include a very high level of system coordination and integration for their facades, combining multiple components, installation trades, and companies. The bespoke design calls for an intricate meshing of glass systems , metal panel, and GFRC panels. The key manufacturers are located in different countries, with glass manufactured in Europe and the curtain wall systems manufacturer AZA INT fabricating products in northern Italy.

    They develop and design unique facade geometries and building envelopes in glass, metal, wood, and other materials for customers. The solution proposed to the team by AZA INT meets the design needs and stringent performance criteria required for this project. This performance was verified by third-party mock-up testing. The fabricated glass products themselves will be sourced from both Germany and Spain, depending on the facade type.

    Overall, the total project requires almost , sqft of curtain wall. Photo courtesy of Columbia Business School Most of is being utilized for mock-up testing, engineering, and coordination of shop drawing details with BIM modeling between trades to alleviate potential conflicts between materials and to best understand how the assemblies merge together with all of the angles, planes, and curves. The west building Commons is an urban—scale living room for students, faculty, and staff, while the east building Forum is a terraced interior landscape that doubles as a —seat lecture hall.

    Each network is a combination of circulation routes, lounge spaces, dining facilities, and study rooms that facilitate planned and unplanned interaction 24 hours a day. The excitement for the project is continuously building as excavation and foundations are underway, but the finished product is not scheduled for completion until Stay tuned for more information as the project progresses! The new development consists of mixed-income luxury apartment rentals, including 97 affordable units and 12 penthouse units.

    The project also boasts two floors of retail space and three amenity levels, including a health club, terrace, 64th floor lounge, and a rooftop terrace. The glazing utilized three types of glass: vision, standard full surface spandrel, and custom spandrel with digitally-printed ceramic frit patterns. All three were fabricated by Viracon. Leasing is scheduled to begin this spring.

    BHP Billiton Petroleum currently has 1, employees in Houston and plans to have about 3, more in this new structure. The new building at the complex has changed the skyline within the Uptown District. The building, designed by New Haven, Conn. BHP Billiton Petroleum did not disclose the cost of the building. Houston-based D. Harvey Builders Inc. Win-Con Inc. There were two main areas that received structural glass on the building podium. The 32 foot tall main wall is 80 feet wide with two angled wing walls at 25 feet wide each forming a trapezoidal shape.

    Each facade had large 5 foot wide by 10 foot tall lites. The walls were able to be base loaded to the ground via the laminated fins to reduce loading on structure at the head.

    Fins were spliced together on the ground and each was set in one large piece for faster erection. There was a unique large door portal situation where the fins came down through the door portal frame to the ground. On the interior, fins were anchored at the base below a stainless steel grate concealing them from view along with the perimeter mechanical systems.

    The Houston skyline has changed and so has the location for many relocated employees who can now interact and collaborate more easily in the same complex. What everyone agrees upon, however, is that the new story building is nothing short of spectacular and an ocean away from ordinary. Guggenheim Museum, Park Avenue South disrupts the urban pack with an unexpected, and exceptionally beautiful, sweet surprise: a tall, rock candyesque crystalline edifice of glass rising up from the ground.

    Legendary French architect Atelier Christian de Portzamparc began designing the building in , and the end product, administered by Handel Architects, remained virtually unchanged. The majority of the construction, overseen by Lend Lease, began in and is now completed.

    How good is the interface when other trades are lacking coordination resulting in leakage and air infiltration? The interfaces to other building components are often neglected, thus we may split a well-designed envelope into two stages: design phase and installation. Consider it has a high thermal transmittance value compare to a solid wallit is brittle, not breathable, and is not safe when it breaks!

    However, as human beings, we still need glass on our curtain walls badly as our instinct wants us to connect to the external environment! You will soon feel uncomfortable if you are inside a concrete box, even though it has an excellent interior decoration.

    According to Susanna, glass is undoubtedly one of the main components of curtain walling. It carries almost all the key aspects in its processing: safety, aesthetics, and thermal. Costs are mainly driven by the glass type and its required performance. One of them is the solar control coating which gives the glass its colour and shade.

    Reflectivity, internal and external as well as light transmission depend on this coating. Many of you may have noticed distortion in the one or the other skyscraper caused by the process when the glass is heat-treated, she adds.

    We understand this is tough to achieve, especially when other coating requirements are prioritised. Nevertheless, our Industry Partners are doing their best to invent new coatings to meet market demands. The essential factor of the glass, however, is safety; it serves as a falling from height protection and human impact from the inside; on the other hand, we have to consider the post breakage behaviour of the different glass types and the usage on higher elevations, eg.

    Electrochromic glass According to Fernandez, glass is the main boundary material between the inside and the outside of a curtain wall, glass gives the possibility to see what is outside, provides natural light, and separate from the weather elements, it also gives us thermal comfort or privacy when required. Apart from all these factors, the glass is also used as a way to express an architectural intent, an idea, or even an economical status.

    Glass fabricators in the last decades have provided a great range of glazing solutions that can combine performance and aesthetics in such way that the possibilities are almost infinite. Another relevant contribution of glass is its contribution to sustainability glass can help to reduce energy consumption and even produce energy by itself.

    Sum believes that lots of people already pointed out most of them, such as faster production and installation, allows differential movements, etc. All the fabrication and assembly operations are in a controlled environment. You have fewer people working on-site, and all of their activities happen on the floor slab — working on a cradle hanging outside a building is not required.

    Susanna notes that the considerable advantage of unitised curtain walls is the efficiency of repetitive units and their installation.

    Once an assembly process is optimised off-site, the time saved on-site is significantly higher than a stick construction.

    Risk Assessment & Method Statement – Install of Glazing & Curtain Wall

    Another decisive factor is the higher quality assurance due to fewer interfaces and workmanship on-site. Working at heights is moved to the inside of the building slab, and interior wall assemblies can be easily integrated. She prefers the unitised curtain wall rather than stick constructions because of these reasons. Of course, it will always be the first discussion if a stick curtain wall is equally suitable, especially when it comes to building movement joints. A unitised system is better in accommodating movement joints and is more flexible in that regard.

    Continuous quality checks are performed during the curtain wall assembly to ensure the performance and quality of the final product. An important advantage, that sometimes is not considered, is the capacity of a unitised curtain wall to absorb the building movements, this becomes a crucial factor for High Rise building construction where building movements are considerable.

    Thermal Performance of Curtain Wall System Unitise bracket Sum points out that thermal performance is one of the essential criteria in the current curtain wall system design, considering energy saving and sustainability is one of the hottest topics that we cannot ignore. Susanna explains that the thermal performance of a curtain wall should be adjusted to its climate conditions. The trend is often to adopt the U-value of colder countries to tropical or as we have it here in the United Arab Emirates UAE hot and arid weather.

    The U-Value originated from the energy transfer through building materials from a high density of molecules to a lower density. The second rule of thermodynamics applies to this theory.

    It is an ongoing debate on how it changes the performance when cooling loads are calculated to keep the heat outside. The same is applicable in cold countries where the temperature delta reaches up to 30 degrees C.

    Tropical climate does not require a strict U-Value and high shading coefficient. Fabrication All the fabrication works will be carried out at the factory by trained workers, supervised by experienced technicians, and hence is subject to quality control procedures.

    Although most of the manufacturing operations are carried out at the factory under the supervision and control of the quality officer, nevertheless, a small-equipped workshop could be erected at the site for handling any minor required adjustments or modifications. Reinforcement is used for transom and mullion and is installed in required areas as per approved drawing Spandrel areas where sunscreen is coming, for example, Resident Housing Spandrel Areas. Fabrication of Brackets: The wall brackets and shoe brackets are designed as per the structural calculation of the curtain wall.

    An 8 mm thick steel plate is used for the fabrication of brackets. The jig is used for the fabrication of brackets. The jig is manufactured as per the dimension required for the brackets by using adequate clearance.

    Steel plates are first to cut into required sizes and holes or slots are made as per the requirement. Plates are clamped to the jigs and tack welding is done within the jig.

    The bracket is removed from the jig and full welding is done from outside the jig. Landing platform shall be arranged at the edge of the building which shall be used to accept the components for distribution onto to the floors.

    The transoms will be securely fastened to the mullions by screws which will form the cruciform joint. Each component will be brought to the point of installation and positioned with the pre-installed wall brackets. Once the proper alignment is achieved the operative will tightened all the bolts.

    The same procedure shall be carried to install the adjacent ladder type assembly. Before installing the adjacent assembly, the connection between the 2-components or ladders, shall be carried on site by fixation of the transoms, from bottom to top. The same procedure will continue till all the Aluminum frames are installed.
