Design and Tender Documentation of Fluid Viscous Dampers

Fluid viscous dampers offer immense benefits in improving structural performance of buildings and bridges as also controlling and saving construction costs. FVDs have an added advantage that they can be easily installed in both new and existing buildings. The design of fluid viscous dampers needs to conform with international building design code ASCE-7. The analysis requirements for design of fluid viscous dampers is considerably different from that followed in design of conventional buildings. Non-linear time history analysis needs to be carried out for design of fluid viscous dampers. There are few specialist structural consultants around the world who have the technical know-how to offer these services to clients. Lack of available talent to design fluid viscous dampers is one of the primary reasons why most are unable to profit from the benefits associated with this state-of-the-art technology. We come on board as damper consultants and offer fluid viscous damper design services including preparation of tender documents. These tender documents can then be used to tender the Fluid Viscous Damper procurement.

Tuned Mass Damper

Dynamically sensitive structures like tall and slender buildings and long span slender bridges are often susceptible to low level of vibrations caused by wind forces or pedestrian loading. These vibrations/ floor accelerations do not affect the structural safety of the building or bridge but cause human discomfort and make these buildings unhabitable for occupation and use. The threshold level below which the floor accelerations are required to be is 15-20 milli G. There are also some structures where a particular frequency of vibration needs to be suppressed and controlled from a structural standpoint. TMDs offer a good and reasonable solution to these issues. We offer services to design, prepare tender documents, supply and install TMDs. We have designed, tendered and supervised the installation of the first TMD project in India. Each TMD is customized both for efficiency in performance and affordability by importing only the key components, which are otherwise not manufactured in the country.

Enhanced Safety for Highrise Buildings using ‘Performance-Based-Design’

India is prone to earthquakes especially in cities that are in high seismic zones 3, 4 and 5. Reputed scientists and experts have predicted a magnitude 8.2 or higher earthquake could strike North India. Under this scenario highrise buildings remain vulnerable and susceptible. Presently due to lack of awareness and technical know-how the highrise buildings in India are being constructed to the minimum safety standard as spelt out by the building code. The minimum safety standard allows for lives to be saved but the building itself can get severely damaged and rendered unusable immediately after an earthquake. We provide design and damper installation services for highrise buildings, so that the buildings move less, and the structural system remains unharmed even after a major earthquake. This not only protects the building but also instils a sense of confidence and safety amongst the occupants. Not many are aware that supplemental damping in highrise buildings is a mandatory requirement in Japan.

Retrofit Weak/Non-Code Compliant/ Damaged Buildings

Like all other things building too require periodic upgrade, repair and maintenance. Over passage of time the building design codes get updated to higher and better safety standards, this does not have to mean that the existing buildings designed to older codes must remain non-code compliant or must be demolished as their safety standard has become outdated. With our experience, expertise and state-of-the-art technology we easily and cost-efficiently update and upgrade existing building to meet and exceed the code level protection. We can retrofit virtually any building to international standard of “Immediate Occupancy”, these buildings are safe for occupation and use even after a major earthquake. Also, many buildings undergo a change of use where occupants want better safety standards either for their families or for their businesses, we offer complete turnkey services for such type of buildings from design to execution. While retrofitting is in progress there is no need to close or empty the building. Commercial building owners, managers and operators will find these solutions an easy fit causing least disruptions.

Value Engineering and Cost Saving in Construction of High-Rise Buildings

Optimized design and construction of high-rise buildings is a complex art. Extra effort put in at the building design stage gives exponential benefits in terms of performance, lifecycle costs savings, marketability of the project and enhancing profits for corporates putting up buildings. Realizing the great benefits of supplementary energy dissipation (dampers) in tall buildings the Japanese building design codes have made it mandatory for all buildings more than 25 meters high to have some form of energy absorbing devices installed. We believe and propagate that high-rise buildings should be designed and built to survive, built to reduce lifecycle cots, built to “Immediate Occupancy” standards, built to enhance occupant safety and comfort. People should not fear staying in highrise building but should cherish it and be proud that their highrise is one of the safest buildings on the planet. We value engineer building designs, can achieve all of the above and save overall building costs at the same time, with our technology building can be built for ready occupation and use even after a major earthquake. We provide value engineering and cost-saving services to our clients.
