Adaptive reuse, regulatory Abstract -Since the late 20th century, the debate over
incentives, reduced construction risks, and aesthetic value also favour rehabilitation. The decision considers specific project needs, with site conditions like cost-efficiency, sustainability, quicker completion, community integration, adaptive reuse, reduced construction risks, and aesthetic appeal influencing the choice.
renovating existing dwellings versus demolishing and constructing anew has intensified, driven by the need to revitalize urban centres. Despite its benefits, rehabilitation is not always the most cost-effective choice, and sometimes, demolition followed by new construction proves more advantageous. In the specialized field of repairs and rehabilitation engineering, expertise goes beyond conventional construction skills, requiring a delicate balance of advanced technology, trends, management, feasibility, and economy. Innovative methods aim to enhance the stiffness of steel members without increasing their weight, with the steel frame construction technique utilizing a grid of vertical columns and horizontal I-beams to support a building's floors, roof, and walls.
1.2REHABILITATION Building rehabilitation involves repairing or modifying a structure to restore its usefulness, extending its service life. Advantages of rehabilitation include environmental sustainability by reducing CO₂ emissions compared to complete demolition and reconstruction. It also lowers costs, minimizes the need for new materials, enhances productivity, safety, and health, attracting investor interest. Rehabilitation can result in a higher-quality product and breathe new life into historic city centres by offering modern apartments in reconstructed buildings. In the construction sector, rehabilitation is expected to become increasingly relevant for people, the economy, and the planet's sustainability.

1. INTRODUCTION Repair and Rehabilitation in Civil Engineering is a skillful practice aimed at extending the service life of structures. It involves restoring a structure to its original state when facing defects, deterioration, or destruction. The ultimate goal is to maximize the functional utility of the structure, even allowing for modifications to meet new requirements. Structures may undergo Repair and Rehabilitation for reasons such as environmental deterioration, changes in functional or loading requirements, or damage from accidents. The process employs systematic approaches aligned with various strategies to achieve a desired level of structural longevity. The lifespan of a structure isgenerally influenced by factors like location, building material, technology, and workmanship.
The rehabilitation of a building involves restoring or renovating it to meet current safety, functional, and aesthetic standards while preserving its historical or architectural significance. This typically includes structural repairs, upgrades to mechanical and electrical systems, accessibility improvements, and cosmetic enhancements. The goal is to extend the lifespan of the building, enhance its usability, and maintain its value for future generations. 1.3STIFFENER Stiffeners, crucial in engineering and construction, reinforce structures and prevent deformation. Used in various industries, they add rigidity and prevent buckling or flexing. Available in different forms and materials based on the application, stiffeners ensure structures withstand loads without excessive deflection or deformation. Their design, tailored to project requirements, enhances overall stability and integrity.
1.1REHABILITATION VS DEMOLITION Demolition means tearing down a structure, while rehabilitation involves preserving and renovating it. The choice depends on factors like cost, environmental impact, and historical significance. Rehabilitating a building, based on its historical or architectural value, cost efficiency, and environmental sustainability, can be faster and integrate
