Of course, everyone wants his or her building to be safe and comfortable forever. Not just buildings, but other forms of social infrastructure essential to people's lives, such as roads and railways, must also be carefully maintained and used over the long term.
Toda Corp.'s renovation proposals and implementation bear in mind the structure's entire lifecycle, from planning and construction, to maintenance and management, to demolition and disposal. The company responds to varied client needs, such as the desire to raise the asset value of facilities or lower their running costs.

Conversion of building uses

Clients can convert the facilities they own to new uses and create new value.
Amidst the growing need for sustainable construction, Toda Corp. recommends conversion of buildings to new uses through remodeling and reuse rather then following the scrap-and-build method of the past.
Conversion from oversupplied markets to markets where better demand is expected can improve business results and raise asset values. Renovation can achieve this at a lower cost than demolition and new construction.

Seismic retrofitting

"Improving earthquake resistance while preserving the external appearance and interior spaces of a historic building" or "maintaining the function of a building while improving its earthquake resistance." Seismic retrofitting is the earthquake-resistance technologies that can meet these seemingly contradictory demands.
Seismic retrofitting adds seismic isolation layers to the foundations or intermediate stories of existing buildings, enabling the addition of earthquake resistance without major renovation of upper structures. As with seismic isolation in new buildings, seismic retrofitting can not only ensure a building's safety during a major earthquake, it can prevent the toppling of equipment and furniture so that the building can remain functional after the earthquake.

Fiber-reinforced sprayed concrete

Fiber-reinforced sprayed concrete involves spraying the polypropylene short fiber SIMLOCK® on the interior surface of existing tunnel linings. This method permits the strengthening and maintenance of load-bearing capacity in tunnels where ground pressure has caused warping, even when workspaces are narrow. The reinforcing concrete can be thinned to reduce construction time.

*SIMLOCK® is a product that has been jointly developed by TODA CORPORATION,Nishimatsu Construction Co., Ltd. and UBE-NITTO KASEI CO.,LTD.

RN-NEO Cutter Method for demolition that does not disturb neighbors

When breakers are used to demolish reinforced concrete walls, loud noise and heavy vibration result. The RN-NEO Cutter Method was developed to solve this problem, as well as to be small enough to be carried in an elevator and light enough to not overload slabs during renovation. The RN-NEO Cutter Method's advantages can be fully realized when inserting slits for earthquake retrofitting or when demolishing reinforced concrete walls.
