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.

ABN Group chose a site in Leederville, WA, for a new state-of-the-art headquarters building. This included a multi-level office, ground floor commercial tenancies, end-of trip facilities, and parking for approximately 160 cars.The project demanded high standards for quality, had a construction time frame of 87 weeks, and was to be five-star Green Star rated.These considerations had an impact on the selection of finish for the car park floors, which is where MARKHAM became involved in the project.AQURON 1000 was selected for enhanced concrete curing, permanent sealing, and deep anti-dust hardening.

The Gateway building In Sydney’s Circular Quay is Australia’s first office tower to use fully integrated touchless 3D fingerprint scanning to allow authorised office workers and guests into the building. The building’s new entrance involves a complex integration of security and technology experts, including Boon Edam, Schindler Lifts, Honeywell and IDEMIA (the manufacturers of MorphoWave fingerprint scanning technology). The solution had to work seamlessly to enhance the user experience and building security for tenants and visitors at the 46-storey landmark building in Sydney’s CBD, owned by Dexus Wholesale Property Fund. Boon Edam delivered the entrance security solution, with Lifeline Speedlane Swing speed gates that are the slimmest in the market, which added to the aesthetics, and helped with design considerations within the width of the lift lobbies. Rising Demand by Tenants for Increased Protection The upgrade project required an entrance security system that incorporated sophisticated security yet kept an aesthetically pleasing and unobtrusive lobby. The ideal solution was found by integrating Boon Edam speed gates, MorphoWave fingerprint scanners mounted on a coordinating pedestal (the Lifeline Boost), Schindler Lift destination control and Honeywell access control technology. This was a response to increasing demands by building occupants to improve the entry security measures to better cater for the protection of employees, visitors and valuable data. A Complex, yet Perfect Orchestration Gateway’s access solution includes a bank of sleek and stylish security speed gates (Boon Edam’s Lifeline Speedlane Swing), which are seamlessly integrated with touchless and intelligent elevator destination control (Schindler Port’s PORT 4 mini) and security access via a biometric fingerprint scanning (IDEMIA’s MorphoWave) – all at one point, enabling quick, accurate and seamless entry to secured areas. These technologies are all controlled by Honeywell’s access control system. Mr Stephen Hodge, Senior Project Manager, Dexus added that “with so many stakeholders, and a strong need for reliability and quality, it was important that everyone knew the goals of the project and worked well together. I’m pleased to say that it was like a perfect jigsaw and everything came together smoothly.” “What was important to Dexus is that we were pushing the boundaries to create better experiences, but we’re only doing so with proven products. Boon Edam’s speed gates have been installed globally and locally, and this gave us added confidence that they were the right product for this forward-looking project,” he said.

54 Mary Street is an office building nestled in the heart of Brisbane. Spanning over 22 levels, it was no small feat for bureau^proberts to carry out a retrofit of the public washrooms. As part of the refurbishment of male, female, and ADA Accessible washrooms across numerous floors, bureau^proberts had to source a large selection of soap dispensers that would be readily available in large quantities – and ideally, in a particular matte black finish. ASI JD Macdonald were perfectly positioned to provide the solution.

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.

Now, and after years of meticulous renovation and restoration, the Miesian Plaza is set to welcome its new tenants, including the likes of Ireland’s Department of Health. Aiming to achieve the highest LEED platinum accreditation, architects Scott Tallon Walker have said their goal is: “To provide Grade A accommodation of the highest modern standard to equal or surpass the finest developments in the market.” Combining sustainable high-grade services all encased in a bronze-tinted double-glazed window motif, the building achieves the architect’s bold aim to create a building like no other. SAS International designed and manufactured products for three of the Miesian Plaza’s blocks. As the building module size is imperial, SAS was able to provide bespoke C profile width to maintain the buildings original 64 1/2” planning module.

Leading Australian community bank, IMB Bank, has installed a series of Boon Edam entrances, including all glass revolving doors, slimline speedgates and a swing access gate at its new building in Wollongong, NSW.IMB moved into the new building in early 2021, and immediately sought to make the entrance open and welcoming to visitors, with entrance security inside to protect valuable data, intellectual property and people.The Boon Edam technology selected is among the most stylish and efficient of the Boon Edam range used by major banks locally, Fortune 500 companies globally, and corporate HQs in 27 countries.The exterior of the building has two Boon Edam Crystal Tourniket all-glass revolving doors, which create a striking first impression. Inside, there are three Speedlane Lifeline Swing speedgates, including one wide lane suitable for disabled access. In one section, there is also a Winglock Swing access gate that separates off a designated meeting space.“After reviewing a range of product proposals, we found that Boon Edam’s range had the ideal combination of aesthetics and security that IMB was seeking,” said IMB Head of Facilities, Greg Dowd.“The security speedgates give us greater control over access to the building, and they alert us to any tailgating or access breaches. Limiting access to only authorised personnel not only protects our staff, but it also protects the data of our customers, which we always store securely,” he said.“As a further advantage, the Boon Edam team integrated the access control system with our RFID (Radio-Frequency Identification) system. This was a big help, because it meant the speedgates were sending data directly to our existing system.”Boon Edam Managing Director, Michael Fisher, says this impressive project will serve as a new benchmark for local financial institutions. “IMB has set the bar high with it’s new Wollongong facility. Every design element has been carefully thought out to be welcoming to visitors and intuitive to employees. We are delighted to have been selected to contribute to the success of this project.”“Boon Edam is a family-owned organisation with a history extending back nearly 150 years, so it is particularly satisfying to work with a community-minded company like IMB, with a similarly long and successful history,” said Mr Fisher.Responsive serviceIn addition to elegant aesthetics and intelligent security, IMB sought an entrance security partner with attentive service throughout the entire project, and then into after-sales service too.“The Boon Edam team was highly professional to work with, and responded adaptively to our needs. Early mornings were the best time for installation work, and their service team accommodated this need right from the start, without a hassle,” said Mr Dowd.“It was clear that Boon Edam takes great care in its products, and that its values as a company were aligned with IMB’s, which are strongly focused on community, family and quality.”Elegant aestheticsBoon Edam’s Speedlane Lifeline series is one of the slimmest on the market, with the cabinet housing measuring as little as 106mm. The slim nature of the speedgate makes it ideal for narrow entrances, lobbies and foyers, where sometimes an extra lane can be added due to its compact size.“The slim design and finishes of the speedgates was what attracted us to the Boon Edam product in the first place. Their overall designs are sleek, modern and in keeping with our foyer design. We could also customise the materials and colours to suit our foyer, and that really sealed the deal,” said Mr Dowd.“For the front entrance, we couldn’t look past an all-glass revolving door. It lets in an abundance of natural light, making the entire foyer a welcoming space for visitors and employees,” he said.Boon Edam’s Crystal Tourniket doors – available in single and multiple entrance options up to 3.5m diameter and height – are being introduced to Australasia after being proven internationally.The Crystal Tourniket is fully compliant with Australian Standard AS1288 (Glass in Buildings), which specifies safe glazing and installation practices when using glass in buildings.“The other Boon Edam product, the Winglock Swing, provides the ideal separation for our meeting space, without needing a full length Speedlane. It’s finishes and design also perfectly match the rest of our foyer,” said Mr Dowd.Boon Edam’s Winglock Swing is constructed from stainless steel and a single glass panel, creating an access gate that is elegant and unobtrusive in nature and design. Winglock is designed to manage bi-directional traffic with effortless ease, using smart, intuitive technology to guide each visitor through to their destination without delay or inconvenience.

SAS International designed and manufactured a range of solutions for the new 75,000 square metres Terminal 2 at Dublin Airport, Ireland. According to Dublin Airport the new second terminal will be capable of comfortably handling up to 15 million passengers per year. Specification demanded that durability, ease of maintenance and acoustics were considered. SAS International worked with architects Pascall + Watson to design the ceiling solution answering the architect’s brief to factor in ongoing maintenance conducted by Facilities Management teams in the future. The design of these large sized ceiling panels required careful consideration at design stage to ensure they would be manageable when working at a height. Designed and developed specifically for Dublin Airport was 35,000 square metres of ceiling systems, installed in the main departure area, walkways and baggage handling areas. This solution looks like any other suspended metal ceiling system as it provides an aesthetically pleasing flush finish. But where this product differs is its ingenious way of allowing access to the ceiling void and services for ongoing essential maintenance. This is of particular benefit in high traffic areas such as Dublin airport as it enables a corridor to remain in use rather than having to close off the entire route. SAS International manufactured the 20,000m2 of large aluminium frames for the fabric ceilings which creates a striking central feature. Working closely with SAS International were local installers Platt and Reilly who applied the stretched fabric to the frames on-site and hoisted them into position. Creating a comfortable environment for traveller and worker was helped with the use of acoustic floating rafts and perforated metal ceiling solutions (with integrated acoustic pads) to provide the necessary acoustic control for this project. Lighting was suspended neatly between the rafts to also provide a modern finish to the corridors. In addition Perimeter heating and air handling grilles also enhance the experience.

Part of a vast regeneration programme to improve student amenities, the UoB invested £60m in a state-of-the-art academic library. The project aimed to celebrate the wider campus architectural styles and improve access to new resources like e-journals and wireless charging stations. Associated Architects chose SAS International to provide the high acoustic and finishing touches to the academic interior fit-out. In order to create an effective library environment, acoustic performance must also be carefully considered. With the aim to create a space suited for thousands of scholars, bespoke acoustic metal wall panels were supplied to the library. Depending on the location of each tile, the panels were finished in white and black-grey PPC or anodised in regency gold. Specified with a 23% or 50% open area, the panels act as acoustic absorbers with an oblong perforation. Each panel is fitted with a black, fleece-wrapped acoustic pad for high performance. The architects specified three additional acoustic treatments for open soffit areas over computer clusters and lounge spaces. SAS500 baffles and bespoke ring shaped and circular rafts were created by SAS International to fulfil this requirement. The discs and raft-halos are an SAS150 hybrid designed to fulfil acoustic and service requirements while contributing to the contemporary look. Consisting of multiple panels, the concealed grid system creates a smooth finish enclosed using a steel perimeter trim. Long 3m baffles were also installed in a continuous sequence along walkways and group study areas. These options provide durable acoustic solution, minimising maintenance and improving access to the soffit and services.

Birmingham New Street Station was originally re-built in 1967 to accommodate 650 trains carrying 60,000 passengers per day. By 2010 it had become the busiest station outside of London, operating at more than twice its intended capacity. The first half of the refurbishment was completed in 2013. The station’s recently updated configuration should now accommodate a yearly 8.3% rise in passenger numbers. SAS International commenced work on the three-phase project in June 2012. NG Bailey and main contractor Mace installed SAS systems across the platforms, the shopping centre and the concourse. Full scale, physical mock-ups of the bespoke ceiling solutions were built on-site to ensure design intent prior to installation. The integration of fans for smoke extraction and complex wind loads had to be considered to guarantee passenger safety. The wind loads were a concern as trains passing platforms at speed can cause considerable negative loads. Bespoke ceilings comprising fixed angle bulkheads were installed in line with the curving platforms. The typically trapezoidal bulkheads were bolted end to end in order to form a faceted layout to follow these curves. Using shared data from the project’s BIM model, SAS International used a point cloud to measure the platforms and 3D model the panels. The model’s geometry revealed that the platforms were all non-uniform. This posed a significant design challenge. The data required careful analysis in order to achieve a smooth curved line within the platform edge. This was essential to provide train drivers with an unobstructed view coming into and out of the station. The SAS International design team was able to rationalise the number of unique panel types down to four. This overcame the driver visibility issue, ensured uncompromised aesthetics and brought costs within budget. Electronic Total Station setting-out techniques were then used to set out the panels along the curve.

How does it work?ECOPact uses alternative materials to reduce the environmental footprint of the concrete mix.ECOPact alone reduces embodied carbon emissions by 30-60% without the use of offsetsSimilar technical qualities of conventional concreteECOPact zero goes one step further buy offsetting the residual emissions of ECOPact concrete to achieve 100 emissions reduction.The issueThe built environment is responsible for 39% of global energy-related emissions. Over a quarter of these emissions arise from running existing buildings, whilst 11% is attributable to the embodied emissions from the construction of new buildings. Did you know – concrete is the most widely used building material in the world? The production of concrete is highly energy intensive and generates significant emissions.Business GrowthAs we continue to grow and expand our store footprint nationally, in 2022 we are building a new home for Universal Store. Our objective is to accelerate our journey to a sustainable future, so we have made it a priority to integrate environmentally sustainable features in the design of this exciting new project. This also entails considering the climate impacts of this project. EcoPact - Zero ConcreteWe will need tons of concrete and other materials for the structure of our new Universal Store home. But the good news is that some pioneers are investing in research and development to deliver carbon neutral concrete.We are working closely with our construction partners - developer TradeCoast Central, and builder McNab to deliver a sustainable building. The Universal Store new purpose-built facility will make use of carbon neutral concrete supplied locally by Holcim. Their EcoPact concrete can be made carbon neutral by compensating for residual carbon emissions. In fact this product is so much better for the planet, it has just won the Best of the Best 2021 Sustainability Awards from Architecture and Design.We chose this product to achieve the following benefits:·Conserve natural resources - the product uses alternative materials (fly ash, blast furnace slag or silica fume) instead of virgin raw materials (mainly limestone and silica). ·Reduce the carbon footprint of the project - this product achieves a reduction of 30-100% of embodied emissions related to concrete usage in comparison to standard concrete. ·Use our influence and leadership to support the transition to a low carbon economy·Demonstrate that a sustainable future is within reach.

The Roads & Maritime Services (RMS) now benefit from a highly progressive workspace in their newly refurbished head office on Parramatta Street. The main aim of the refurbishment project was to improve facilities and collaborative spaces for staff and visitors. However, a significant challenge for the contractors was to keep all existing communications rooms fully operational throughout the project. Achieving the Aim: SAS800 Trucell ceilings were installed in the open plan lounges and stairwells of the renovation. Creating a grid of squares, strong lines stretch the length and breadth of the collaborative space. The system gives a decorative feature to the fit-out with the illusion of a much larger space for activity-based working. Comfortable lounge furniture and bright colours have also been chosen to encourage communication and create a flexible working space. Meeting the Challenge: Specified with a lay-in exposed grid, each tile slots in place without the need for gaskets or cutting. With the building in constant use, installation was quick and easy keeping the project on schedule with minimal disruption. Popular in Australian CBD property markets, the refit considers occupant well-being with Grade A ‘end of trip’ facilities. An upgraded lobby area also contributes to the value-added space with an improved experience for employees and visitors alike.

One New Change features SAS International bespoke metal ceiling panels with an expanded metal mesh, finished in silver, red and black. The ground-breaking, bold and perceptive £300 million One New Change mixed-use development project won the MIPIM AR Future Project Award 2010. Now complete, the building has become known as the ‘Stealth Bomber’ after the radar-proof combat plane that inspired its faceted form and has also won a RIBA 2011 Award for London and LDSA Building Excellence Award. The design incorporates pedestrian arcades converging at the core of the building, reinstating a historic north-south pedestrian route and allowing new panoramas of London’s landmark St Paul’s Cathedral. SAS International supplied the ceiling solution for the retail corridors of the development with a concealed suspension system, working closely with the architects to create a result where no visible fixings can be seen through the ceiling plane. To complement this, bespoke metal ceiling panels were produced with an expanded metal mesh, finished in silver, red and black. A challenging material to work with, to ensure the mesh held a uniform shape and corners for the panels could be formed accurately, SAS International’s solution was to create a ‘picture frame’ behind each panel. This also helped to provide support for the concealed attachment bolts. Design challenges at One New Change included the building grid size and shape (it was termed the most difficult site in Europe), the complex geometry of the structure (including some tight ceiling to structural beam heights), and a shared fire strategy between retail and office storeys. Requirements to achieve an environmentally-friendly building, complying with Part L and BREEAM ratings, were also critical and the design uses a materials palette of limestone, metal, mirror and a new method of fritted glass on the exterior to help shield the interior from glare.
