At Navni Post Tensioning Systems Pvt. Ltd., we pride ourselves on turning complex engineering concepts into reality. One of our most exciting and technically challenging recent accomplishments is the successful execution of a 30 ft cantilever post-tensioned beam at a private farmhouse project in Hyderabad, owned by Mr. Krishna Reddy.
Cantilever structures are always a test of engineering precision and material behavior. Extending a 30-foot cantilever beam without compromising on strength, durability, and aesthetic elegance posed a unique set of challenges — one that our design and execution teams eagerly took on.
This farmhouse project wasn’t just about building a structure; it was about pushing the boundaries of what’s possible in residential architecture through advanced post-tensioning techniques.
Navni was entrusted with the complete design and post-tensioning execution for this remarkable cantilever element. From conceptual design to on-site stressing, our expert team meticulously planned every detail to ensure structural integrity and performance under live and environmental loads.
Key deliverables included:
Custom post-tensioning cable profile design optimized for the 30-foot projection.
Careful selection and installation of high-strength PT tendons and anchorages.
Precise tensioning and stressing operations using advanced hydraulic jacks and calibrated equipment.
Comprehensive quality control measures, including load tests and stress monitoring to validate design assumptions and field performance.
Project: Private Farmhouse
Client: Mr. Krishna Reddy
Location: Hyderabad
“Engineering Strength and Possibility Beyond Limits — One Beam at a Time.”
30 ft Cantilever Beam:
A significant engineering feat in residential construction, ensuring minimal deflection and optimal crack control.
Material Optimization:
By adopting post-tensioning over conventional RCC, slab and beam thicknesses were reduced while increasing load-carrying capacity and lifespan.
Design Flexibility:
Allowed the client to enjoy an unobstructed open space beneath the cantilever, enhancing the architectural appeal and utility of the outdoor area.
Durability & Safety:
Enhanced durability through controlled cracking, improved resistance to environmental factors, and long-term performance assurance.
Executing such a large cantilevered span in a residential setting comes with its share of logistical, technical, and safety challenges:
Managing deflections and stresses at the free end of the cantilever during and after construction.
Ensuring seamless coordination with other trades on-site without disrupting post-tensioning operations.
Handling the precision stressing operations with minimal tolerances to achieve the exact prestress levels required.
Navni’s experienced team overcame these challenges with rigorous planning, technical expertise, and on-site adaptability. Our custom PT solutions and real-time monitoring ensured that the structure performed precisely as intended.
