Efficiencies that flowed directly onto the construction team, supporting trades and ultimately the developer, delivering a high performance solution within budget, ahead of schedule all the while guaranteeing a compliant and comfortable environment.

About the ProjectThis Child Health and Learning facility in Manly, deliversspecialist child healthcare for up to 15,000 families a yearfrom rural, regional and remote New South Wales andbeyond.The new facility will integrate a state-of-the-art child schooland health service that will accommodate regional childrenand families nationwide.This six storey building includes school classrooms,consultant and observation rooms, a paediatric oral healthunit with a dental and orthodontics room, ophthalmology,occupational therapy, sensory rooms and a telecare centre.ChallengeOver 80% of construction litigation and defect claims are a result of water ingress, of that 80%, almost 30% of those are below grade issues. (City Futures Research Centre UNSW).The two biggest waterproofing challenges for this build were:1) Below Grade - Non structural Blinding Slab, 4 metres below sea level and less then 50 metres from Manly Beach. This build had decanters pumping over 1.3 million litres of water per day awayfrom the site during the construction phase.2) The creation of a waterproofing solution which would not fail if the membrane was penetrated, be it in the pre or post construction phase.Due to the proximity to the beach and the build having a raft slab in the basement, a standard cookie cutter below-grade waterproofing solution was not an option for this build.Tremco SolutionTremco were asked to provide a solution for this complex build. The biggest and most demanding waterproofing areas within the build that needed attention were:1) Below Grade - 50 metres from the ocean and 4 metres below sea level, we needed a reliable waterproofing solution, that would also be robust enough to withstand any punishment tradesdelivered post installation, we recommended and used Paraseal SW (Saltwater). Paraseal SW is a multi-layer sheet membrane waterproofing system consisting of a self-sealing, expandable layer of bentonite laminated to an impermeable, high density polyethylene (HDPE).2) iAuditor reporting- iAuditor is an onsite quality assurance program Tremco conduct for the builder and applicator to ensure our products are being installed correctly and to specification. This gives the builder the confidence that there will be no waterproofing defects within the build.Overall, both the builder and developer were happy with the end result, which provided the warranty and quality required of such a development.

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.

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.
