    🌍 Keller s’engage pour le climat ! 🌱 En 2024, nous avons lancé notre bilan carbone en partenariat avec Global Climate Initiatives afin de mieux comprendre et réduire notre empreinte carbone. Cette initiative s'inscrit dans notre volonté de : ✔️ Évaluer précisément nos émissions de CO₂ ✔️ Nous former au bilan GES ✔️ Suivre notre impact environnemental ✔️ Répondre aux exigences du Groupe Keller en matière de neutralité carbone ✔️ Satisfaire les attentes de nos clients ✔️ Contribuer au plan neutralité carbone du gouvernement français 📊 Des actions concrètes pour un avenir plus durable Suite à notre bilan, nous avons mis en place quatre groupes de travail axés sur nos principales sources d’émissions : 🔹 Matériaux et services entrants 🔹 Énergies 🔹 Déplacements 🔹 Actifs et gestion des déchets Ces équipes ont défini des actions concrètes qui seront progressivement déployées afin de réduire notre empreinte carbone et avancer vers un futur plus responsable. 💡 Chez Keller, nous sommes convaincus que chaque action compte. Ensemble, faisons bouger les lignes pour un secteur plus durable ! 🙏 Un grand merci à Global Climate Initiatives pour son accompagnement dans cette démarche essentielle ! #kellerexcellence

    A dear topic for me once again. My friend Solve Hov and his colleagues at NGI - Norwegian Geotechnical Institute and KELLER have conducted a field study related to wet deep mixing.   Solve Hov, Henrik Meland, Anıl Helvacıoğlu, Robert Thurner, and Åse Marit Wist Amdal. Distributed Fiber-Optic Strain Sensing in Deep Mixed Columns. J Geot Geoenv Eng, 2025, 151(2), 05024015. https://lnkd.in/dqAp3i2q   I’m really excited to share this cool study they conducted in Trondheim, Norway. They integrated fiber-optic cables into wet deep mixing columns, the very first time anyone in the Nordic region has used Distributed Fiber-Optic Sensing (DFOS) technology. DFOS was used to measure temperature, strain, and vibrations, and it worked alongside the usual geotechnical tools like pore pressure and settlement measurements. The main goal was to capture how the columns deformed under load, and the sensors delivered an impressive resolution of 2–3 cm. With the columns loaded with up to 5.5 m of soil, the sensors clearly picked up the applied loads. What’s interesting is that the data showed significant variations in deformation along the length of the columns, highlighting a non-uniform behaviour, maybe expected since this type of soil-binder material has high property variability. Plus, the study confirmed that the sensors stayed firmly in place under heavy loads and that their readings were in line with conventional deformation calculations.   This study featuring the advanced technique is highly sought after. Previously, measuring deformations at such high resolution was nearly impossible, especially inside the column. Now, this technology enables us to analyse load transfer and distribution between the soil and columns more effectively. Managing load distribution along the entire column proves challenging in design, especially when installing floating columns or columns of different lengths. A deeper understanding will definitely lead to more cost-effective designs by the possibility to optimize the area ratio (based on column diameter and cc-distance), particularly in regions with low embankments or floating columns. I really look forward to reading further studies on this topic.   //S #KTHSoilAndRock

    🏗️✨ Vi på KELLER Grundläggning är stolta – men inte förvånade – över att vår kollega Tünde är en av de 51 förebilder som valts ut i processen för att bli Årets Byggkvinna 2025 av Byggföretagen! Av 113 nominerade har Tünde gått vidare som en av kandidaterna som inspirerar, visar vägen och gör skillnad i en bransch där vi behöver fler kvinnliga ledare. Tünde är inte bara en tekniskt skicklig geotekniker med erfarenhet från flera länder i Europa – hon är också en ledare i en operativ roll, mitt i produktionen, med ansvar för personal, ekonomi, projektledning och tekniska lösningar. Hon leder – och levererar – varje dag. Med sitt tekniska kunnande, sin erfarenhet och sin starka position i produktionen är Tünde en förebild i byggbranschen. Hon visar att jämställdhet inte handlar om var du kommer ifrån, utan om kompetens, beslutsamhet och att våga ta plats. Grattis Tünde – vi hejar på dig hela vägen till finalen! 🙌 (De tre finalisterna presenteras 8 maj och sen röstar juryn fram vinnaren, som avslöjas vid ett digitalt event 16 maj.) #åretsbyggkvinna #byggbranschen #ledarskap #geoteknik #grundläggning
