Mass Timber Structures: Opportunities and Challenges While the sustainability and aesthetic appeal of mass timber are undeniable, it’s important to acknowledge the technical challenges it brings. Beyond the well-documented concerns around fire safety, acoustics, and water vulnerability, timber shrinkage poses a significant risk over time. Unlike materials like steel or aluminium, timber can experience substantial shrinkage, which may exceed the thermal expansion of aluminium façade profiles or the live load deflection values of a steel frame. This discrepancy introduces complex design and coordination challenges for façade engineers and other disciplines. As exciting as mass timber structures are, they also bring a host of risks that the industry might not yet be fully prepared to address. Are we ready to tackle these challenges at scale? I’d love to hear your thoughts—how can we innovate to mitigate these risks while leveraging the benefits of timber? #MassTimber #FacadeEngineering #ConstructionChallenges #SustainableDesign

A flat roof that is properly cared for can last five decades. That is not the most common lifespan for a roof, but it is attainable when all the right decisions are made, from the underlying structural design and integrity up to the choice of materials and the quality of the installation. With maintenance, even the most basic kinds of flat roofs—those covered with a waterproof membrane and perhaps a layer of gravel—can become long-lived and low-energy.

Lately, I have two questions: Can reinforced concrete buildings be made more sustainable? Can the CO2 emission of a building structure be close to zero? 🌿 Here are some examples of the structures we install. The decision to combine reinforced concrete with light structure walls really improves the indicators. This path was chosen by some of our partners in the #Scandinavian markets. It is clear that the INHUS team has a lot of practice and expertise in the installation of such buildings. This is really a significant part of our construction activities. The logic behind this type of building can be justified only if the external facade is additionally covered with clinker bricks. This way #longevity can be maintained. The option where the wooden panels are simply fixed on the walls of light constructions does not seem to be a sufficiently durable and good solution. Therefore, it’s important that you have the knowledge to make the right decisions. INHUS aims to make buildings and the environment more sustainable – not only with words, but also with actions.

The construction method for retaining walls significantly influences their performance, durability, and cost. At the core of successful retaining wall construction is the careful balance between structural requirements and site-specific conditions. Factors such as soil properties, wall height, and intended use all play critical roles. This article explores into the various construction methods for retaining walls, discussing their applications, advantages, and limitations. Whether it's gravity walls, cantilever walls, or anchored systems, understanding these techniques ensures effective and efficient wall design. 🔗 Read the full article here: https://lnkd.in/dAP3Cb_2 #RetainingWalls #ConstructionMethods #StructuralEngineering

IWI Project Due To Start Shortly - Historic Property - Solid Walls(No Cavity) After a site visit to this large historic property and a hygrothermal risk analysis done via WUFI, (in order to ascertain a safe level of wood fibre insulation to be used, so as not to cause interstitial condensation). The insulating of the inside of the external solid walls is due to start shortly. A layer of lime insulating plaster will be used as a levelling / dubbing out coat prior to the wood fibre insulation being applied. It's imperative that there are no air pockets between the back of the wood fibre boards and the wall, as a dew point can form at this point. Lime plaster will be used to finish the wood fibre boards, with a base coat of Baumit RK70 and a finishing coat of Baumit KlimaGlatt. Watch this space, I will post again once installation starts!

Architectural coatings, usually made of PVDF, ETFE and FEVE. Architectural films (typically PVDF and, primarily, ETFE) are applied on various surfaces in buildings as protective coating in applications where a lifespan of several decades is needed. These coatings protect the substrate, which can be any material, from weather and environmental conditions. Applications include coatings of bridges and other industrial structures, as well as large constructions, such as roofs of stadiums and domes. They can be transparent, allowing natural light in the building and reducing the need for artificial lighting, and consequently energy usage. #fluoropolymer #etfe #fep #pfa #architectural

Unlike traditional retaining walls, embedded walls are anchored deep into the ground, enhancing stability and making them ideal for deep excavations or steep slopes. This article discusses the types of embedded retaining walls, including sheet piles, contiguous and secant bored piles, king-post walls, and diaphragm walls. Key design principles are explored, from calculating earth pressures and determining embedment depth to ensuring stability against overturning and sliding. A detailed worked example illustrates the process for designing a sheet pile wall for a sandy soil site.

Managing congestion in the cavity used to be simpler. With thicker slabs and fewer fire performance requirements, we had more space and flexibility in design. But today, evolving building standards and performance needs have brought new complexities: Thinner Slabs 🏢 As we shift toward leaner designs, thinner slabs limit space for critical installations like masonry support, increasing the risk of clashes. Higher Fire Performance Standards 🔥 Stricter fire safety regulations reduce available space, as barriers require minimal penetration, leaving less room for other components. To keep pace we’ve leaned into early coordination, accurate load calculations, and strategic integration of elements as key methods for managing complex designs. How are you adapting to these design challenges?
