Comfortable residential environment

Takenaka’s technologies for solving “sick building syndrome” problems

From the planning phase to the design and construction phase, we provide solutions that satisfy our customers for the “sick building syndrome” problems that have recently become an object of public concern.

Long-term use of buildings

Base isolation retrofit work can be done while the building is in use

Installing base isolation devices (seismic isolation rubber or dampers) in the foundation of the building improves the building’s earthquake safety.

Efficient use of energy

Construction technology contributes to energy conservation

By adopting the precast concrete (PCa) method for beams and floors in building frame projects, we significantly reduced the amount of formwork, reinforcement, and temporary fixtures on the site.

Careful use of items not easily disposed of

Resource recycling construction system

We encouraged the overall reuse of building materials and equipment. For steel frames, we developed a simple column-beam joint method that enables steel frames to be reused as materials for temporary fixtures as they are after demolition work.

Avoid polluting the earth

Demolition technology for incineration facilities prevents dioxin exposure

We sealed the incineration facility with sheets, prevented dust from dispersing during demolition work, and monitored the work using a dust measurement machine and a TV camera. We are committed to safety and security.
