The project scope involves the design, supply, and installation of a state-of-the-art base isolation system, ensuring compliance with the latest structural code standards. This proactive approach will significantly bolster the building’s seismic performance, safeguarding the continuity of essential national defense operations in the event of a major earthquake.

RBRA conducted a detailed structural design and analysis and base isolation system of the building. This state-of-the-art facility will serve as a hub for local governance, providing seamless access to essential services while promoting civic engagement and sustainability.
This is the first municipal building in the Philippines with a base isolation system.
We also installed the base isolation system in the 1st Quadrant of the Building

Multi-purpose Infectious Disease & Tropical Medicine Geriatric Building of San Lazaro Hospital in Quiricada Street, Sta. Cruz, Manila. It is the first seismically isolated hospital building in the Philippines. It ensured the protection of the equipment and occupants during a strong earthquake as one of the retained tertiary hospitals of the Department of Health (DOH).

RBRA undertookthe design, supply, and installation of a sophisticated base isolation systemto retrofit St. Joseph Hall, a 4-storey reinforced concrete structure. Thisenhancement significantly improved the building's seismic performance,providing enhanced resilience against potential earthquakes and ensuring thesafety and security of its occupants.

RBRA made theMabini Building of DLSU Lipa the first school building retrofitted using aseismic isolator. It was a prominent building on the western half of the De LaSalle University Lipa Campus at the J.P. Laurel National Highway, Lipa,Batangas.

The Lanai and Central House Administration Buildings, which consist of a 2-story and 4-story reinforced concrete structure, were retrofitted with a state-of-the-art base isolation system designed, supplied, and installed by RBRA. This retrofitting has significantly enhanced the buildings' overall performance and resilience. This innovative approach not only strengthens the buildings' structural integrity but also ensures optimal performance, resilience, and safety for their occupants, setting a new standard in modern engineering practices.

Designed to create a modern, functional, and resilient city hall that meets the evolving needs of the Pasig community. This state-of-the-art facility will serve as a hub for local governance, providing seamless access to essential services while promoting civic engagement and sustainability. The first city hall in the Philippines adapted the base isolation system.

Structural engineering consultancy services for proposed structural audit and retrofitting design (base isolator and viscoelastic damper)

Originally built in 1883. Like other buildings in Manila, it has undergone many reconstructions because of tragic events. The retrofitting of its pillars and walls was recently completed. RBRA designed, supplied, and installed its seismic isolators, making San Vicente De Paul Parish the first earthquake-proof church in the Philippines.

The COA Main Building showcases advanced structural engineering with its reinforced concrete framework. The addition of viscoelastic dampers to retrofit the building marks a significant advancement in safety, providing reliable, long-lasting, and cost-effective vibration isolation. These enhancements support the facility’s resilience, ensure uninterrupted operations, and offer comprehensive protection for occupants and assets.

Built between 1923 to 1924, the China Banking Corporation Building at the corner of Dasmariñas St. has undergone restoration with RBRA to bring about Manila's revival and preserve the next generation's heritage. The massive undertaking required extensive architectural, electrical, insulation, mechanical, plumbing, and structural works for disaster preparedness and earthquake resiliency. It is one of the most faithfulrestorations done on any building in the Philippines as it is the first 100-year-old reinforced concrete building retrofitted with a viscoelastic damper.

RBRA conducted a detailed structural design and analysis of 21-storey and 16-story residential and commercial buildings at 1 Bataan Village, Udyong Horizon by the Bay in Bataan. RBRA also designed a seismic isolator to minimize story drift and floor acceleration by 90% of the said residential buildings.
