"concrete blocks"

OverviewSet in the heart of downtown Toronto, the Ontario Court of Justice is the largest courthouse in Ontario and a benchmark for contemporary institutional construction. Completed in 2024, the project brings together 63 courtrooms and 10 conference settlement rooms in a LEED® Gold certified facility that reflects modern civic values—transparency, accessibility, and sustainability.Master Builders Solutions Canada Inc. played a key role in ensuring the structural concrete met the performance demands of this high-profile project.The ChallengeDelivering nearly 48,000 m³ of ready-mixed concrete in a downtown location posed numerous technical challenges. The structural design demanded high compressive strength, consistent workability, and durability to support complex load paths, security zones, and a tall atrium enclosed by a 20-metre glass façade.The project team required concrete solutions that would:Maintain workability over long pumping distances and vertical placements,Ensure strength development for critical structural zones (such as core walls and transfer slabs),Limit thermal cracking during curing in massive pours,Integrate seamlessly with staged slipform and rebar installation schedules.These demands were intensified by the need to meet LEED® Gold sustainability targets, tight construction timelines, and high public visibility.The ResultsMaster Builders Solutions Canada Inc. partnered closely with St Marys CBM to optimize concrete performance across all phases of construction. A suite of high-performance admixtures—including water reducers, retarders, and strength-enhancing additives—was deployed to address the project’s structural and logistical complexities.Key contributions included:Enhanced workability retention for long-distance pumping and complex placements, reducing placement time and labour.Improved early- and long-term strength development, enabling faster formwork cycling and reliable performance in high-load areas.Mitigated thermal buildup in mass pours to control cracking and ensure durability over the structure’s lifecycle.Admixture compatibility with supplementary cementitious materials (SCMs), aligning with the project’s environmental goals.By tailoring admixture solutions to the precise performance needs of each mix design, Master Builders Solutions supported consistent quality and efficiency throughout the build.The Ontario Court of Justice now stands not only as a civic institution but also as a demonstration of what is possible when modern structural design and advanced concrete technology are brought together. The project exemplifies how Master Builders Solutions helps construction teams deliver on performance, sustainability, and long-term value.

Soaring to a height of 1,776 feet (540-meters), the 2.6-million-squarefoot (242,000-square-meter) skyscraper known as One World Trade Center in the lower Manhattan district of New York City is a marvel of design and engineering. Construction of the building, previously called the Freedom Tower, began in April 2006 and at the time was the tallest building in the United States.The Challenge Sustainable design was a central theme to One World Trade Center’s development, with the Port Authority of New York/ New Jersey imposing a strict requirement for the replacement of Portland cement with recycled materials. In addition, extremely high performance concrete was necessary to meet the compressive strength requirements of the steel and concrete structural columns, which ranged from 14,000 psi (97 MPa) to 12,000 psi (83 MPa) for the lower 40 floors and 10,000 psi (69 MPa) to 8,600 psi (59 MPa) for the upper floors. The 12,000 psi (83 MPa) concrete phase of the project was the most challenging, with the engineers, owners and contractors all having their own requirements and specifications.The ResultsThrough Master Builders Solutions‘ Green Sense Concrete mixture optimization service, Eastern Concrete Materials was able to proportion an EF Technology® concrete mixture with 71% cement replacement. The mixture replaced Portland cement with the recycled materials, non-cementitious fillers and specialized admixtures to exceed all the performance targets specified by the One World Trade Center project stakeholders. This EF Technology mixture was used for the 38,000 yd3 (29,000 m3) of concrete needed for the columns through the first 40 floors. To quantify the environmental impact of sustainable concrete for the structure, an Eco-Efficiency Analysis was conducted, using a methodology validated by NSF International, to compare the specialized EF Technology mixture to a reference mixture. Some practical equivalents for these savings are: Water savings equal to 1,177,329 half-liter bottles of waterReduced carbon footprint equal to 1,835,494 gallons of gasolineFossil fuel savings equal to 29,872 barrels of oil

Start at the foundation where the loads imposed by a steel frame are up to 50% less than those of a concrete alternative. There is evidence in the field and through third-party case studies and comparative cost studies that steel building systems offer significant cost benefits over competitive building materials when the total cost of construction is considered.

Prairie Hills Junior High School's south-facing elevation features a glazed aluminum curtain wall that incorporates PPG Solarblue and PPG Solarban 60 glazing. Parts of the curtain wall had to meet a two-hour rating because it was adjacent to a two-hour block wall through the building's interior. SAFTI FIRST® supplied SuperLite® II-XL 120 IGU in GPX® Curtain Wall Framing in order to meet ASTM E-119/NFPA 251/UL263 requirements.

Traditional parking garage designs used to have opaque fire rated building materials like concrete, masonry and drywall which made these spaces dark, cold and uninviting. That all changed, thanks to the emergence of new technology, clear, fire resistive glazing tested to ULC/CAN S101 up to 2 hours that are available in large sizes and low-iron glass make-ups with high visible light transmission for superior clarity and color neutrality.

Codes required fire wall separations between parking garages and businesses, markets, homes and other uses. Architects can replace entire walls with glass to open up buildings like never before. For example, SuperLite® II-XL in GPX® Architectural Series Framing by SAFTI FIRST® is a USA-made fire resistive transparent wall system that blocks radiant heat and meets the same stringent ASTM E-119/ UL 263/ NFPA 251 code requirements that any opaque fire rated wall must meet.

By offering a combination of European system design and Chinese materials and fabrication, Yuanda continues to provide world-class and cost-effective façade solutions to the UK, France, Germany and Switzerland. The BriefThe Harbour Central project was conceptualised to transform the London Docklands into an up-and-coming residential area. The project, which comprises 5 residential towers, boasts a total façade area of 63,000 square metres. The façades were designed to superimpose a metal mesh on the shadow box area and showcase the aesthetics of the blocks. Moreover, the team of architects at Rolfe Judd had very precise specialty glazing requirements for the buildings. “We discussed product aesthetics, construction and design considerations. The architect had a specific idea in mind regarding the kind of colour finish they required and Future Glass was able to provide the perfect gold and silver tones that were needed.”- Mr Alain Anthony, Design Director, Yuanda EuropeThe Future Glass SolutionThe search for the perfect glass led us across countries and continents. After an exhaustive search, the silver mesh was procured from Germany while the gold mesh was procured from Italy. Since the glass panels required were of a very large size, an innovative solution was sought by which panels of a maximum size of 1,500 mm x 4,000 mm were created with the metal mesh suspended in the cavity of the IGU. To put concerns about mesh sagging and distortion to rest, a sample panel was provided to the client. For energy efficiency, Climaguard Premium 2T, a high performance Low-E coated glass was procured from Guardian Glass in Europe. The glass itself is made up of a combination of products. The outer-lite is a clear ecoLAM (HS) of 10.76 mm. The expanded metal mesh infill is within a 24 mm black spacer with argon gas. Finally,  the inner lite is a 6 mm clear ecoFACADE (HS). Despite the complicated product combination, the performance specifications were designed to meet the client’s requirements perfectly. A total of about 4,100 square metres of finished insulated glass units with expanded metal mesh were provided for the Harbour Central project.The Future Glass AdvantageAt Future Glass’ state-of-the-art facility in UAE, a dedicated workforce was tasked with ensuring the high-specialty glass was treated in a sterile environment where temperature and humidity could be controlled. Each glass panel is handmade and pieced together under the supervision of qualified engineers. The finished glass panels were placed in IPPC-certified wooden crates for transport. As per local requirements, each piece was individually banded and then shipped to Yuanda’s Shenyani factory. From there, the panels were carefully assembled into a framing system that was delivered to the site in London. Despite the fact that the materials were sourced from various countries, the logistics and operations team took every precaution necessary to ensure zero breakages during the delivery process. In case panels needed to be replaced, we did what was necessary without impacting the timelines, even though it was difficult to procure smaller quantities of mesh from the supplier.
