Warwick Hotel Rittenhouse Square in Philadelphia, PA, is quite satisfied with the functioning and cost savings of their Boon Edam Tournex revolving door. The Tournex is an example of a classic automatic revolving door and is designed to handle high capacity applications. The historic building housing the Warwick Hotel Rittenhouse Square originally had a manual revolving door flush with the building’s facade. Somewhere along the way, it was decided to remove the relatively smaller gauge revolving door and replace the entrance with a double set of sliding doors. “Our HVAC system was designed for a revolving door entrance,” said Ray Hewitt, the hotel’s Director of Engineering, “we wanted to put a revolving door back in to address the negative pressure we were experiencing in the lobby.” That negative pressure was pulling in cold air during the winter months, and cooled, conditioned air was escaping out the double doors in the summer. During a complete lobby renovation project a few years back, designers worked to return to a revolving door lobby entrance. Because the Warwick is in a historic building, they could not change the facade of the building, so they pushed the entire entrance into the lobby itself. The architects and the designer chose a 12’ diameter Boon Edam Tournex automatic revolving door, with three door wings and a highly polished (mirror) stainless steel finish. The Boon Edam door is enclosed in a stylish glass cube, accented with purple neon lighting. Now, those entering the hotel first pass through a double set of sliding doors at the building envelope, leading to the revolving door. Swing doors are also available on either side of the revolving door to enter the lobby itself. The effect of the sliding doors and the revolving door in a cube is to virtually eliminate air flow from outside in, and vice versa. The Warwick has 301 hotel rooms and 106 permanent residents. On any given day, between guests, residents, staff, and visitors, up to 1000 people are passing through the entrance. Since the installation of the new entrance, the effect has been night and day—guest and visitors utilise the lobby space longer and in greater numbers. A big community table is usually filled all day long and the lobby is accented with attractive fireplaces. The hotel lobby also offers two full service food and beverage outlets (Bluestone Lane & Prime Rib Steakhouse), with a third to be announced sometime this year. In addition to a now grand sense of arrival and more useable, comfortable space, the new entrance is also paying dividends on energy savings. “With the old entrance, our HVAC was running constantly, it could not keep up. Now, the unit can shut down periodically; that’s good for the health of the system, and we’re seeing substantial savings on energy bills,” said Hewitt. The Boon Edam revolving door has an important feature for installations like a hotel or large office building—in the event of an emergency, the doors stop and the wings can be “book folded” to create wide open ingress and egress. The hotel has a maintenance contract with Advanced Door, but since installation the Boon Edam revolving door has been virtually trouble free.

The first installation in Australasia has been completed of Boon Edam’s Circleslide architectural curved automatic sliding doors that elegantly cater to access for disability needs of modern and traditional buildings. The Circleslide installation for Mark Moran Group at Pacific Highway Warrawee on Sydney’s North Shore provides a prestigious, weather-protected entrance to a development of up-market aged care accommodation built by Next Group for Benson McCormack Architecture.  The door’s practical advantages also apply to a wide range of buildings in Australia and New Zealand, including commercial and public and private facilities, including offices, aged care, health, hospitality, restaurant, retail, tourist and transport facility uses, says Boon Edam Australia Managing Director, Michael Fisher.Circleslide installations consist of two sets of curved sliding doors – one on each of the entrance and exit sides – to provide a larger opening than traditional sliding doors, and retaining the elegant shape of revolving doors. This extra space is a major advantage for people with a disability, or those that require mobility aids. Enhanced accessibility Circleslide curved automatic sliding doors provide spacious and comfortable access for everyone using them including especially people with disability and their carers, and particularly people those with mobility issues who rely on wheelchairs, mobility scooters, wheeled walkers and other mobility devices commonly used in workplaces and public facilities. “Access to public and private facilities is an important and increasing issue for more than five million Australians and New Zealanders living with disabilities. This growing sector of the population includes the higher proportion of older people with limited mobility, including more than 750,000 Australasians who use mobility aids,” says Mr Fisher. “Where building professionals seek to provide for such people but want to retain the prestigious shape and functionality of revolving doors, Circleslide doors are an ideal solution that provides the additional capacity required,” he says. Circleslide doors complement Boon Edam’s global ranges of revolving doors, which is one of the world’s most comprehensive ranges. Their elegant design and access control functionality are preferred by architects, builders and designers for Fortune 500 companies in 27 countries. Customisable features The Circleslide door has an optional “winter mode” whereby only one sliding door opens at a time, which can reduce HVAC losses and contribute to the overall sustainability of the building. Like all Boon Edam revolving doors, Circleslide is available in a wide variety of colours and finishes, so it can be customised to the look and feel of contemporary and period buildings. The self-learning technology incorporated in the curved sliding door mechanism ensures extremely quiet and smooth movement of the doors. Options include: Interlocking modeConnection to external alarm system (e.g. fire alarm, smoke detector)Push-button free outKey impulse switchDirection sensitive motion detectorsGlass protection sheetsFloor matsAuthorised night entry·        Air curtain technology to create a barrier of air flowing from the revolving door’s canopy or sides to further extend revolving doors’ built-in advantage of excluding heat or cold to save HVAC costs through their unique always-open, always-closed configuration.  Night Locking Options include an electromechanical lock that can be unlocked with a key or by means of an optional key impulse switch.

The City of Boston is known for many things – from Fenway Park to the Boston Marathon to the bar from Cheers, the city is full of iconic landmarks, events, cultural assets, education centers, and more. The City is also recognised for its vast history, especially downtown, where hundred-year-old buildings have been preserved or restored. There is also a mixture of new property development, including 33 Congress Street, in the heart of the financial district, which combines the best of historical design with new construction. 33 Congress incorporates more than 400,000 square feet of office and retail space, transforming the historic neighborhood and positioning the area as a dynamic downtown destination. The project was designed by Arrowstreet, an award-winning architecture and design firm, and was led by Jason King, AIA, LEED, AP, BD+C, Senior Associate for Arrowstreet. Blending Historical Features with a Modern Design According to King, the 33 Congress Street building consisted of three different structures that were built at separate times: in 1904, 1906, and in 1922 and then all combined into one space. While the space functioned as one building, there were three separate elevator cores, sets of restrooms, sets of stairs, and more. Those entities needed to be reconfigured into one. The most striking feature of 33 Congress is a new, modern glass and steel structure, containing 6 additional floors of office space that sits on top of the original three masonry buildings. Another important project goal was to upgrade the main lobby to a modern design that allowed public access, increased security for building employees, and respected several historical aspects. “We needed a way to get people into the new, main elevator lobby quickly due to the high volume of traffic that we were anticipating would take place after the redesign,” King said. “We also wanted to create an entrance that would create a better flow of entry from the sidewalk into the building.” The original building had an existing revolving door, but it was small and surrounded by stone. “It was dark and uninviting,” King said. “We were creating an open and airy Class A lobby space and wanted visitors to clearly see the ornate, coffered ceiling and experience the grand and historic nature of the lobby as they entered.” Revolving Door and Speed Gates Provide Aesthetics and Function King implemented a Boon Edam Crystal Tourniket manual revolving door to lead visitors in the double height lobby space. The Crystal Tournket is constructed virtually completely from glass with only a few stainless steel accents to ensure the solidity of the revolving door. It fits seamlessly with modern glass facades but can also be a beautiful eye catcher in more traditional or classic designs. For employee access, the building’s previous design did not incorporate turnstiles to the elevator banks. “The building did have card reader access, but only at certain doors and locations,” King said. King installed four lanes of Boon Edam Lifeline Speedlane Swing speed gates and two Winglock Swing model access gates to provide secure employee access to the building’s upper floors. The Lifeline Speedlane Swing speed gate manages and channels the flow of people entering and moving around buildings. It employs sensors that detect visitors approaching, with pulsing light strips to guide the user. A sleep function saves on energy use. It can be customised with dimensional and glass choices, including corporate identity colors or other options, so that it either blends-in or stands-out from its surroundings. The Boon Edam Winglock Swing is constructed from stainless steel and a single glass panel, and is unobtrusive in nature and design. The access gate easily manages bi-directional traffic, with LED lights that signal if the gate is in use or on standby. The access gate ties into a manned security desk located near the front doors. Employees gain access to the building through either the Lifeline turnstiles, or a Winglock Swing access gate, while building visitors can receive credentials at the security desk. King said, “We started the process looking at Boon Edam from a security and an aesthetic standpoint. We went through multiple product options but always had a Boon Edam product as the basis of the design. We have been happy with Boon Edam entrance solutions and we are planning to use them again for future projects.”

The Burj Khalifa – formerly the Burj Dubai – is a legendary building that can only be described in superlatives. At 828 metres high, it is the tallest building in the world. The Burj Khalifa has 160 floors, more than any building in the world. The building also has the highest floor, the highest façade made of aluminium and glass, the highest nightclub and the highest restaurant, the highest service lift and the lift with the longest travel distance. Finally, the building has the highest positioned revolving doors ever installed in a façade worldwide. In less than 30 years, Dubai has become the leading city in the Middle East and is known for its architectural and technical excellence. The Burj Khalifa has become the symbol of this progress. The Burj Khalifa also takes the title of the highest structure in the world back to the Middle East; the Great Pyramid of Giza used to hold the title 4 millennia ago. International Collaboration The tower was designed by architectural firm Skidmore, Owings & Merril, known for their designs for the Willis Tower (formerly the Sears Tower) and the new One World Trade Center in New York. The three-pronged design is based on the spider lily desert flower and consists of three elements around a central core, with the elements spiralling upwards. It can rightly be called an international project: the construction team consisted of Samsung Engineering & Construction employees from South Korea in collaboration with Besix from Belgium and Arabtec from the United Arab Emirates. The UK consultancy Hyder Consulting was responsible for overseeing construction of the building. In total, companies from more than 30 different countries contributed to the construction of the Burj Khalifa. A Windy Challenge The wind is quite a challenge when building a skyscraper of this size. Without additional measures, the top of the building would move so much from side to side due to the wind that people would become seasick. Dubai is also regularly tested by the shamals: sandstorms that can last for days. As the outer façade of the Burj Khalifa contains an enormous amount of glass, these weather conditions presented a considerable challenge. The three-part design proved to be the solution because the spiral floors break the wind currents around the building, resulting in a stable structure. The World's Highest Revolving Doors Skidmore, Owings & Merril's design includes an observation platform on the 124th floor of the building. Two glass revolving doors provide access to this room. At 442 metres above the ground, these are the highest positioned revolving doors ever installed in the façade of a building. The revolving doors must also be able to withstand an extremely high wind load of at least 3000 Pascal, which corresponds to an F3 class tornado. The Burj Khalifa required two automatic revolving doors with a diameter of 3,000 mm and a total height of 2,700 mm; the cover could only be 300 mm high with the motor installed. Generally speaking, a revolving door with these specifications would only be able to withstand wind loads of up to 689 Pascal. It was clear, then, that not every revolving door manufacturer could supply an entrance that met these requirements. Challenge Accepted Koninklijke Boon Edam was one of only two companies invited to devise a system for this challenge. There were two main problems that had to be solved: the round sides of the revolving door had to be strong enough to resist the wind, and the door set had to be properly fixed so the door wings could not be blown off during a storm. Boon Edam worked closely with Mace, the Hyder Consulting Group, Samsung Engineering and Construction and Turner Construction, the subcontractor, to develop a system that met all these requirements. During the first phase of the process, the second company invited to tender had to give up because their design did not meet the challenging conditions on the 124th floor. Boon Edam persisted in its efforts, and after conducting various wind load and glass tests, it became possible to adapt the construction of the Tourniket to the requirements of the Burj Dubai. A Tornado-Proof Revolving Door at the Burj Khalifa Our proposal for the Burj Khalifa consisted of a Tourniket with specially reinforced door frames twice the width and thickness of a normal revolving door. These were securely anchored with special bolts under the floor to guarantee the structure's rigidity. Although most revolving doors are installed on the top of the subfloor, this door was installed under the top finish layer of the concrete floor. To guarantee the stability of the door set, an extra-thick steel frame was added to the structure. This allows the door wings to easily withstand the wind pressure. Expansion on the 148th Floor in 2014 Boon Edam installed the same specially designed Tourniket revolving door on the 148th floor as on the 124th floor. However, the new project brought an extra challenge: transporting all of the materials from the basement of the building to the 148th floor. First, the materials had to be transported in one lift to the 111th floor. They were then transferred to a second lift, from where everything had to be moved manually from the 149th floor to the 148th floor, to the door's location. Special Projects Based on Standard Solutions The revolving doors we created for the Burj Khalifa were an extreme challenge. The experience and expertise of our technicians combined with the tried and tested technology of the Tourniket enabled us to develop a successful solution. Both revolving doors are now used daily and give visitors a spectacular view of Dubai. The glass design beautifully complements the modern façade of the observation platform and puts Dubai's beautiful skyline in the spotlight.

There is a saying that “Everything is Bigger in Texas,” and the Dallas, Texas police department is no exception. The city of Dallas is ranked in the top 10 cities in the U.S. in terms of population, at 1.2 million people. The Dallas Police Department is the ninth largest municipal police force in the U.S., based on 3,012 sworn officers. It is led by Chief of Police, U. Reneé Hall. Security a Concern When Designing HQ Building The department is located in the Jack Evans Police Headquarters building, which was built in 2003. It is 358,000 square feet, has six floors, is spread over a three-acre site, has a separate 1,200 car parking garage and a two-acre, open parking lot for additional visitor parking. Prior to 2003, the department was housed in the circa 1914 former City Hall Building. The Jack Evans Police Headquarters building was under construction when 9/11 terrorists flew airplanes into the World Trade Buildings in New York. That event was preceded by the Oklahoma City Murrah Federal Building bombing in April 1995. Therefore, security was a concern in its design. Police officials worked with a Police Design Consultant – McClaren, Wilson, and Lawrie Architects of Phoenix – to help design the building to resist a terrorist attack and isolate potential hazards. The building also needed to control visitor traffic and access. On an average month, there are 5,000 public visitors to the Jack Evans building. In addition, shots fired at police buildings nationally are not uncommon, says Paul M. Schuster, Senior Corporal/Facilities Management for the Dallas Police Department. “For the most part they are random, single shot drive-by shootings. Often, the officers are unaware that the building has been shot at, until they find a bullet hole in the brick or glass. Increasingly, police tend to be a symbol of government and some citizens see that as a visible target to lash out at. Police officers are trained to expect the routine types of calls, such as domestic violence, traffic accidents, and other crimes. Yet they must be flexible to anticipate the non-routine that can be dangerous and change in a heartbeat.” An Active Shooter Incident Led to an Increase in Security On June 13, 2015, after midnight, a 35-year-old male placed a duffle bag with a remote-controlled bomb to detonate later between cars in the parking lot of the headquarters building. The suspect then began shooting continuously at the lobby windows. Officers responded to the scene, a vehicle chase began, and the incident ended outside the city. Luckily officers in the lobby took cover and were not injured. Following that incident, the Dallas Police Department conducted a security assessment of the building and also at seven patrol stations throughout the city. The assessment included testing various construction materials for bullet resistance to various types of weapons. Gensler Architects and Guidepost Solutions, LLC developed the solutions and plans. “Yesterday we were concerned about handguns, today we are worried about rifles, and the idea of terrorism is always present with outright attack or bombs,” Schuster notes. “The police officers and police staff only want a place that is safe and where they can do their good work.” Funding of $1.3 million was approved to upgrade the lobbies of the seven patrol stations to withstand rifle rounds, and $1.9 million to improve headquarters lobby security, and to upgrade an aging security system. Turner Construction Company and Convergint Technologies, LLC conducted the renovations and security technology integration. Challenges to the Security Design The headquarter’s lobby was initially designed as a two-story glass-walled structure, with an information desk and public records service windows. Visitors were allowed free entry into the lobby and were only screened in an open area to the side if going to other floors. “The challenge in upgrading lobby security was the two-story lobby entrance glass. “In addition, there were concerns about keeping an ‘open’ and friendly service concept in mind and ensuring that the lobby would not resemble a ‘fortress’,” Schuster notes. Screening Room with Security Revolving Doors to Contain Incidents The solution was to keep the existing exterior unchanged and focus on adding a layer of security once a person enters the lobby. Visitors now enter the headquarters and immediately proceed to a side room where security screening is conducted. A new secondary wall with bullet-rated glass and solid bullet resistant wall materials was constructed inside the lobby to channel visitors to the room. Once inside the screening room, which also has bullet resistant walls, the visitor has belongings x-rayed, and they walk through a metal detector. In the event that anyone was to produce a gun and begin shooting, the incident could be contained inside that room. Once a visitor has been cleared, they proceed into the main lobby via a Boon Edam Tourlock 180 security revolving door. This automatic, four-wing door is the most advanced, security revolving door in the Boon Edam product range that offers maximum throughput, allowing users to enter and leave the building simultaneously. In the event that a large number of persons try to force their way into the facility, the Tourlock 180+90 will determine that more than one person is trying to enter and will reject the person and lock out any others from entering. Once a visitor is ready to leave the lobby and exit the building, they pass through another Boon Edam Tourlock 180+90 that leads to a vestibule with exterior swinging doors. In the event that someone tries to go back into the lobby from the front vestibule area, without going through the security screening room, the Tourlock security revolving door will reject their entry.
