Company Philosophy

Observing
The Five Construction Principles

Realizing Ideal Situations
in Construction

Infrastructure is a basic need for civilized societies. "The Five Construction
Principles" are the universal criteria for construction method selection, byconsidering ideal situations for construction work under public perspective.
In any construction project, the five aspects i.e. Environmental Protection,
Safety, Speed, Economy and Aesthetics, should be fulfilled in the form ofequilateral pentagon.
Giken is a "New Methods Development Company", which provides original
foundation structures and methods that fulfill The Five Construction Principles.

Social Responsibilities

Coexistence of Environmentand Civilization
Because of environmental disruptions, natural disasters and complex and aging
infrastructures, the present-day society is facing more and more challenging
situations.
We at Giken are creating an environmentally friendly sustainable society byproviding infrastructures for safety and prosperity based on the advantages of
the Press-in Method.

History of Innovation
Press-in Principle
The Silent Piler grips previously installed piles
and presses next pile into the ground withstatic load, by leveraging reaction force(extraction resistance force) of reaction piles.
The Press-in Principle enables our compact
machine (Silent Piler) to generate a large
force by obtaining leverage from the Earth.

Historical Innovation ofFoundation Workusing the Press-in Principle
Giken turned the "Press-in Principle" to practical use and eliminatedconstruction pollution caused by pile driving
Giken Group was established in 1967 as a company to solve construction pollution.
Giken developed the Silent Piler in 1975, which was the first ever realized practicalproduct of the Press-in Principle virtually eliminating noise and vibration.
Since then, Giken has consistently been developing machines and methods based on
the advantages of the Press-in Method.

History of Innovation

GRB System
The GRB system applies the Press-in Principle which states that areaction force is obtained from completed piles. In this way, all of the stepsof the process, from transporting and pitching the pile, to pressing it in,can be carried out from a position on top of the existing piles.

Achieves "Minimum TemporaryWork Method" by InternalInnovative Creativity

Because all of the equipment is self-supporting and grips onto thecompleted piles, there is no risk of overturning, and the area affected by
the works is reduced to the width of the machinery on the piles.

Make the Impossible Possible by Overcoming Various Site Restrictions
on Construction Works
The advantages of the Press-in Method are that it is not only virtually noise and vibration
free, but it also has an epoch-making "Minimum Temporary-Work" aspect, which wasrealized by internal company innovations.
Therefore, even over water, on sloping or uneven ground, in narrow spaces, or locations
with restricted headroom, the GRB system has essentially no need for any temporarystructures, like platforms or access roads, and can focus efficiently on the purpose of the
project, "building the desired infrastructure".
Also, difficult ground conditions, such as cobble or boulder mixed soil and rock, wasovercome by our original innovative creativity, and expanded the applicability of thePress in Method dramatically.

Tubular piles with relevant bit configurations
are installed by the "rotary jack-in" system
without affecting the environment orsurroundings. Therefore, it meets the higher
demand to renew and strengthen
infrastructures in a socially conscious way.

History of Innovation

Structural Revolution ofDisaster Prevention Infrastructureusing Implant Structure
The Press-in Principle allows consolidation with the Earth,forming resilient structure
Implant Structure that is securely consolidated with the Earth is highly resistant toground displacement caused by the motion of earthquakes, tsunami, and other external
forces, thus, serving as a "resilient " disaster-prevention infrastructure.

Implant Structure
The Implant Structure consists of a structural member that is combined with a frame and foundationthat are embedded into the ground where they are securely supported by the ground.
The structure carries horizontal and vertical loads, using the "size of the structural member" and the"embedded depth into ground". As a result, it exhibits high strength as an aggregate, having
individual structural members that are supported by the ground.

Culture Above-ground& Function Underground
Creating unique underground space with harmony ofaesthetics and function
Both ECO Park and ECO Cycle are built in a cylindrical underground space, using thebest of press-in technology.
Only a small entrance booth is fixed above ground, therefore, an environmentallyconsiderate design and efficient parking are met at the same time.
The outer shaft is a cylindrical Implant Structure, which well withstands seismic externalloading. This income generating facility can also double as a foundation forsuperstructure.
Installing function under-ground, thereby utilizing aboveground for public amenities.
Giken's underground facilities, based on the Implant Structure, contribute to society
friendly and environmentally considerate aesthetic urban alternatives.

Ditching Old Common Practices andChanging the Industry

Changing Industry's Direction
from "Permanent Structure" tosustainable "Functional Structure"
Promoting Implant Structure-related Technologies Worldwide asa Total Package Solution with "Minimum Temporary Work" Concept
As "IEMOTO" i.e. the head of Press-in Technology, Giken group evaluates lifecycles of
the Implant Structures, through design, planning, construction, maintenance anddemolition to meet the purpose of projects.
Without being restricted to precedent common practices and standards, Giken globallypromotes a new construction standard i.e. "Functional Structure", which is designed
based on "Minimum Temporary Work" Implant Structure. The Functional Structure serves
necessary functions to cover required design life.

Verifying Structures and Methods Scientifically for Worldwide Acceptance
The real-time information of piling operation can be monitored and recorded to observeand review the operation.
Based on the monitoring data (Pile Penetration Testing), Giken Group has a system for
automated operation to optimize the piling operation and bearing capacity verification
technology. Currently, Giken is developing a structure sympathetic nervous system for
substructure information modeling.
Also, in order to validate theory and full-scale testing, Giken started the collaborative
research with the University of Cambridge, UK.
In addition, Giken was involved in the establishment of the IPA (International Press-inAssociation) in 2007 and is supporting their research in "Press-in Engineering", tovisualize the interaction of piles with surrounding soils.
Only universal standards backed by science can be a driving force of the "Construction
Revolution".
