As an infrastructure service provider with "People, Dreams and Technologies"
as our motto, we have always aimed to refine our technology in order to design
infrastructure which enables people to pursue their dreams while enjoying theabundance of nature.
In the future, the development of a sustainable society will require even morediverse approaches, including regional revitalization, digital transformation (DX),and the creation of a carbon-free economy. National resilience has to be strengthened
against increasingly frequent and severe natural disasters, and the issue of declining
and aging populations in developed countries also needs to be addressed.
The People, Dreams & Technologies (PDT) Group Co., Ltd. was newly established
as a holding company to further advance the technology we have developed so far,and allow us to quickly and flexibly respond to a wide variety of social needs byproviding services related to all kinds of infrastructure.
Moving forward, we intend to build a diverse array of corporate alliances whilefurther strengthening the governance of the PDT Group. In addition to our corebusinesses of disaster prevention and infrastructure development, our goal is to offera broad range of services both in Japan and overseas. We remain fully committed tothe creation of a safe and secure environment in which people all over the world havethe freedom to pursue their dreams.

The Kushima Bridge is a three-span continuous steel box girder bridge with an orthotropic
steel deck. The project included the construction of two pier foundations in the sea
channel. Steel pipe piles as foundations were driven into the seabed after excavationin 30m deep water, while the lower parts of the reinforced concrete piers were being
manufactured on land. The piers were then brought to the site to be installed on the piles.
Footings were made by casting underwater non-segregate concrete on the seabed, and theupper parts of the piers, which are the deepest “bell-type submarine foundations” in Japan,
were constructed in-situ.

The Shin-Fujigawa Bridge is a steel-concrete hybrid arch bridge crossing the Fuji River.
This hybrid type bridge uses concrete in both the arch rib and vertical members which
are mainly subject to axial force, and also applies steel to the stiffening girders which aremostly subject to bending moment. Particularly, the arch rib developed by high strength
concrete was a cost-effective construction method which led to weight alleviation and costsavings.

For large-scale suspension bridges and similar structures with few precedents, models as similar to
the real structure as possible are made of not only the girders and towers, but of the whole bridge.
These models are then used to make highly accurate wind resistance studies and dynamic analyses,
the results of which are reflected in the design.

Dynamic Analysis

Evaluation of Detailed Designusing Study Models

For structurally complicated locations, study models are created for individual members in order to ensure they fit into the overall structure.

Building Information Modelling (BIM) and Aesthetic Design
BIM Designing
BIM has become a mainstream technology in infrastructure design andinnovation. Comprehensive 3D models can be created for structures suchas bridges, and additional information such as time, cost and materials canthen easily be added and managed. BIM can be applied to all processes fromstructural design to construction and maintenance, and we have also applied
the technology to aesthetic design.

Road

Expressway / High Grade Road
Roads are important networks which connect regions and promote logistics andlocal economic development. Construction of wide-reaching road networks such as
expressways is indispensable for the economic growth of any country.
When constructing expressways, it is importantto accurately select suitable road standards,
geometry, and road structures such as bridges
and tunnels to match the requirements of road
users and regional needs. High-grade roads
also play a major role for disaster prevention
and management.
We strive to make the most of limited budgets
when carrying out planning and design for road
construction.

Road
Interchanges connect wide-reaching and local
road networks and are important facilities forregional development.
We have extensive experience of the selectionof structures in consideration of trafficc o n v e n i e n c e a n d t h e r e g i o n a l e n v ir o n m e n t.

Road Facilities / For All Road User
Road networks also require immigration facilities, rest facilities, and service areas which can be used totransmit information in case of accidents and disasters. It is also necessary to plan motorbike/ bicycle lanes
and underground utilities in order to use the road space effectively in conjunction with road maintenance.

Effective use of road space (utility duct)

Example of customs/border and rest facilities at international highway.

Rural Road / Missing Link
Roads are essential for the life of local residents. It is therefore necessary to constructroads suitable for the local environment as well as alternate roads which can be usedduring disasters to enable roadside residents to live safely and comfortably.
In addition to enabling the movement ofv e h i c l e s a n d p e o p l e, r o a d s a l s o p r o m o t eeconomic development and provide both

Traffic management / Road Safety
Congestion and accidents cause problems for urban roads and traffic, and lead to a deterioration of traffic conditions. It is therefore important toanalyze the underlying reasons and develop accurate countermeasures. It is also vital to comprehensively consider the improvement of roads andintersections, the development of public transport, as well as the use of Intelligent Transportation Systems (ITS) and related software.
In order to mitigate traffic congestion causedby economic development, multi-modals o l u t i o n s s u c h a s B u s R a p i d Tr a n s i t ( B RT )systems are effective for traffic management.

The use of ICT for Road & Traffic
When people’s standard of living increases as a result of national economic growth,
the rate of car ownership also becomes higher. Based on experiences from Japan,
an increasing number of cars leads to congestion, deterioration of the traffic
environment, and a loss of economic activity, resulting in a negative spiral. It is thus
necessary to ensure an optimal traffic circulation so as not to lose opportunities for
economic development and to enable the continued growth of the economy.
On the other hand, the communication infrastructure in developing countries hasdeveloped rapidly as they are not burdened by the history of ICT in Japan, and they
already have an environment in which they can introduce more advanced
technology. The PDT Group fully utilizes ICT technology cultivated in Japan,
and is therefore able to propose comprehensive solutions for maintenanceand traffic environment improvement to its client countries.

Roads are part of the main infrastructure and need to be prioritized and developed for urban and regional development
projects such as industrial parks. It is important to plan and develop the road and traffic network to meet the objectives
and needs of the development area as this has a significant impact on future convenience and value.

Our role as a consulting company involves supporting urban development by performing basic design for roads,
bridges, soft soil improvement, utilities, and landscape design.

part of the Hii river mainly for the purpose of flood
control in the watershed area that has been suffered fromwater damage back through Edo era. Utilizing experiences
in major dam projects, KISO-JIBAN now also partakes in
Small-hydro power projects in Southeastern Asia such as
Indonesia and Philippines.

Since undertaking the soil investigation for Cagayan Railway Project in Philippines
in 1959, We have proactively participated in overseas projects in spite ofchallenging situations and have deepened the relationship with global clients.
In 1974, we opened the first overseas branch office in Singapore and now have
expanded our overseas bases to Kuala Lumpur, Jakarta, Hanoi, and Manila.

Geotechnical Risk

Geotechnics
34

Geotechnical risk is the risk to onshore and offshore construction work created by the site
ground conditions. It is a key and a very important element that needs to be considered in all
construction.
Risk can be assessed, managed, and minimized. But to that end, unforeseen geologicalconditions and the associated geotechnical problems need to be correctly understood sincegeotechnical risks are as varied as the geological conditions. That is to say, appropriate
investigation in the early stage of a project is crucial in reducing the risks.
KISO-JIBAN’s comprehensive specialty in geotechnical engineering will set priorities for the useof limited resources and time, and provide the underpinnings for geotechnical risk management.

In an earthquake-ridden country as a leader of geotechnical engineering,K I S O - J I B A N p l a y e d a s i g n i f i c a n t r o l e i n d r a w i n g u p J a p a n ’s g o v e r n m e n t a lguidelines regarding earthquake resistance and has long contributed in developing
earthquake resistant technologies including seismic risk assessment, liquefaction
analysis and countermeasure designing.
At the time of the Great East Japan Earthquake (March 11, 2011), on the very next
day of the quake, we sent a special engineer team to the devastated area to assess
the extent of the damage, investigate the cause of damage, and provide consultationon the design for reconstruction.

Soil Investigation

If the circumstances allow, the most ideal way to understand the unforeseen
ground condition is to crack open the Earth in half. But when that’s not possible,
the best we can do is to collect information based on boring survey, sampling,laboratory test, and geophysical exploration.

Boring Survey
The better we know, the better measures we take. To know better, KISO-JIBAN iscommitted to innovating the technics in obtaining information of the ground as
close to what it is.

Gel-Push Sampler is speciall y designed to contain liquid pol ymer inside to
reduce the friction between sample core and sampler tube in the course ofsampling. With Gel-Push samplers, we overcame the difficulty in sampling
undisturbed soil samples on fragile soft ground.

Value Chain of Economic Infrastructure
Urban and Regional development requires the effective use of local resources. For example, Eco-tourism projects are envisioned in a country where
nature and historical heritage are abundant. We are working hard in various regions in developing new businesses that will make the best use of local
resources while simultaneously expanding their basic infrastructure needs. These three categories are closely related and all of them have an essential
role in making the value chain function.
