We understand that seismic retrofitting is much more complex than conventional repair or rehabilitation, which is why we carry out a streamlined retrofit analysis. The first step is to assess the condition of the structure, and then we evaluate the seismic forces and finally choose the most suitable retrofit strategies and construction. We assist you with….

Retrofitting requires specialized monitoring and analysis, which only we are capable of performing. At Jacob Engineers, we perform a thorough investigation of the structure requiring retrofitting and propose a practical, cost-effective, and technically sound solution.

Performance and utility of industrial buildings, institutional buildings, urban transport structures, marine structures and commercial spaces can be greatly enhanced through retrofitting or rehabilitation. In some cases, the structure needs to be strengthened as per the requirements of the current codes of seismic design. Jacob Engineers provide expert analysis and designs for various retrofitting and rehabilitation projects.

Frequently Asked Questions


Retrofitting refers to the process of strengthening or modifying an existing structure to enhance its resilience, performance, and safety. It involves implementing structural upgrades or improvements to ensure that the structure can withstand increased loads, comply with current building codes, and mitigate risks from hazards such as earthquakes, hurricanes, or other environmental factors.


Retrofitting is important for several reasons. It helps enhance the structural integrity and safety of existing buildings and infrastructure. It allows structures to meet current design standards and regulatory requirements. Retrofitting can also extend the lifespan of a structure and protect investments by reducing the risk of damage or failure during extreme events.

Retrofitting may be necessary in various situations. It is commonly required for older structures that were not built to withstand current loads or have outdated construction methods. Additionally, retrofitting may be necessary after a structural assessment or evaluation identifies vulnerabilities, such as signs of distress, deterioration, or when new codes and regulations are introduced.


Retrofitting offers numerous benefits, including improved structural stability, enhanced resistance to natural disasters, increased occupant safety, and reduced property damage. It can also lead to energy efficiency improvements, enhanced functionality, and increased property value. Retrofitting can be a cost-effective alternative to complete reconstruction or replacement of a structure.

Retrofitting is typically carried out by qualified structural engineers or firms specializing in retrofitting services. These professionals have expertise in assessing structural vulnerabilities, developing retrofitting strategies, and implementing the necessary modifications. Depending on the scope and complexity of the project, other professionals, such as architects, contractors, and building inspectors, may also be involved.

Common retrofitting techniques include adding structural reinforcements, such as steel bracing or concrete jackets, to strengthen vulnerable components. Other techniques include installing shear walls, upgrading foundation systems, improving connections, or implementing base isolation systems. The specific retrofitting approach depends on the characteristics of the structure, the identified vulnerabilities, and the desired level of performance improvement.
