Extension of Existing Civil Structures (Vertical & Horizontal Expansion)

We specialize in the execution of structural extensions over pre-existing RCC buildings, delivering safe, efficient, and technically coordinated solutions for vertical and horizontal expansion. These projects require a deep understanding of existing structural behavior, load transfer mechanisms, and execution constraints, especially when carried out in live operational environments such as hospitals, institutions, hotels, and commercial buildings.

Unlike greenfield construction, extension projects involve working with an already built structure, where every intervention must be carefully engineered to ensure that additional loads are safely transferred without compromising structural integrity. Our approach combines detailed structural assessment, steel–RCC integration, and phased execution planning, enabling seamless expansion with minimal disruption.

Our Core Capability:

Our expertise lies in integrating structural steel systems over existing RCC frameworks, allowing additional floors, service structures, or functional spaces to be added efficiently. The use of steel significantly reduces dead load compared to conventional RCC, making it ideal for vertical expansions where foundation capacity is limited.

We ensure:

  • Phased construction planning
  • Controlled working hours and zones
  • Safety barriers and protective measures
  • Minimal disturbance to occupants and operation

Types of Extension Works

  • Addition of multiple floors over existing buildings
  • Terrace-level expansions and deck slab floors
  • Lift structures and vertical service cores
  • Fire ramps and access systems
  • Mezzanine and intermediate floors
  • Building width/length extensions
Why Steel-Based Expansion?
  • Reduced load on existing structure
  • Faster execution compared to RCC
  • Minimal structural intervention
  • High flexibility for design and modification
  • Ideal for retrofit and upgrade projects
Key Technical Considerations
  • Accurate load path and structural compatibility
  • Proper anchoring and connection detailing
  • Controlled deflection and vibration behavior
  • Coordination between old and new structure
  • Compliance with IS / seismic / safety standards

Our Execution Strength

  • Proven experience in hospital and institutional expansions
  • Expertise in steel–RCC integration systems
  • In-house fabrication ensuring quality and precision
  • Strong coordination between design, fabrication, and site teams
  • Ability to handle complex, time-sensitive projects

Conclusion

Extension of existing structures is one of the most technically demanding aspects of construction. It requires not just execution capability, but engineering judgment, precision, and coordination. At Aditya Vardhana Multiservices Pvt. Ltd., we bring all three together—delivering expansions that are structurally safe, operationally seamless, and future-ready.
