Technology for Building
Now is the time to construct buildings that can last more than 100 years and abandon the concept of“Build and Scrap”. The long-lifebuildings are not only physically durable but are also flexible in layout to accommodate the changing needs and expectation of different
era. The objective is to provide quality living space with due consideration for the environment. We have the technology and expertiseto create such buildings and we can contribute from the planning stage through construction stage till long term maintenance program.

Radiant heating and cooling system using Thermo Active Building System (TABS) and ground thermal energy
This cooling and heating system circulates cold and hot water through pipes buried in the concrete slabs of each floor to store
cold and heat in the concrete structure of the building. It actively utilizes radiation from the slabs. By storing cooling and heat atnight, the air conditioning load during the day is mainly handled by the outside air, and the load on the heat source equipment
is equalized, resulting in significant energy savings by downsizing the heat source capacity. In addition, unlike general air
conditioning, TABS air conditioning does not cause discomfort
or temperature irregularities due to airflow, and the quiet
and comfortable space improves intellectual productivity.
Furthermore, for geothermal heat utilization, U-shape tubes forheat collection are installed in boreholes and piles, and water iscirculated in the tubes to exchange heat with the ground. The
heat thus obtained is used directly for slab cooling and as aheat source for water source heat pumps.

The concrete controlled drying shrinkage strain(Fit-crete)

Expanded base cast-in-place concrete piles to resist uplift forces

Fit-crete can control the drying shrinkage strain of concrete in a range fromnormal levels to zero shrinkage. It is possible to provide high-quality, value-added
concrete that maintains its performance and aesthetics over the long term in
RC structure facilities with fair-faced finishes, etc. This technology was jointly
developed by HAZAMAANDO CORPORATION,
Kumagaigumi Corporation,
TODA CORPORATION,NISHIMATSU Construction,
Fujita Corporation, andConceptual diagram of drying shrinkage
MAEDA CORPORATION.

This is a design method that takes into account the uplift resistance ofthe expanded base of a belled pile. The wedge-shaped expanded basecan be considered to have a greater
uplift resistance force than the shaft
shape, which makes it possible toreduce the shaft diameter and shorten
the penetration length. This technology
was jointly developed by Yusho Kogyo
Co., Ltd. and Towa drill Kogyo Co., Ltd.,
both of which are companies engaged inConceptual diagram of construction

Technology for Civil Engineering
Civil Engineering involves a wide range of technology in various disciplines. New technology taking account of environment andlandscape has been developed for construction in order to increase capability of structure. Improvement of technology also has been
done to increase efficiency of work towards“Work Style Reform”.

Tunnel construction technology for Labor saving and quality improvement

Our construction technology

The self-compacting concrete tunnel lining system

Tunnel form management by laser scanner

As facing the aging of construction workers and a decreasein the number of skilled laborers, we developed the tunnel
lining construction system using Self-Compacting Concrete(SCC) for aiming to improve productivity and lining concrete
quality.
In this system, we place SCC through the injection holeinstalled at the lower edge of lining formworks and fill it
without consolidation and other operations. We proved theusefulness of the system and high completion through thefull-scale construction test conducted at the Sato Kogyo
Technology Centre SOU test field. Our future goal is toautomate tunnel lining construction by adopting this system
in construction sites.

Conventional construction methods
・Concrete is placed into tunnel lining formworks by switching concrete pump
pipes sequentially.
・Concrete is consolidated by construction workers with concrete vibrators.

Build MeisterTM is the work progress control software which can find out thebest solution for the concrete lining work.This software advises practicalsolution for the thickness of concrete lining by the accurate analysis ofas built shotcreted surface and excavated surface detailed condition.And
input 3-D Laser scanner surveyed information of the actual shotcreted
surface before starting excavation work shall be displayed or output forunderstanding the shotcreted and excavated surface condition easier. These
procedure by using this software is able to achieve approximately 80% oftime saving compare with the former concrete lining construction procedure.

Enlargement of live line tunneling method

For tunnel in widening construction, this method isapplicable to wide ranges of geological substances fromhard rock to soft rock, and uses moveable blast protector.
It is possible to shorten construction period and to reduce
construction cost while ensuring safe passage of othervehicles.

Compact shield tunneling method

Tunnel design and construction technology with consideration for economy and the environment
Design and construction of super-large section tunnel with an inner section aspect ratio of 0.52
Kesennuma Tunnel No.2 is one of the largest cross section tunnel inJapan as per its entrance of Iwate Pref. side has 3 traffic lane becauseof ramp. In the original design, this tunnel’s inner section aspectratio γ (= Inner height / Inner width) was 0.57 as commonly applied.
However, if the tunnel cross section area could be reduced, it leads toreduce not only the excavation volume and temporary support work, butalso maintenance work in future. Therefore, we proposed to reduce theinner section aspect ratio and we put this design into execution.The
ratio value γ shall be finally decided to 0.52 by analysis of temporary
support, lining and invert. By this engineering design, tunnel crosssection area shall be reduced to 189m2 from original design 202m2.
Cutting area for tunnel entrance could be also reduced. Our design andconstruction contributed to not only the reduction of construction andmaintenance cost, but also landscape protection and environmentalloading reduction by reduction of carbon dioxide due to construction
and reduction of forest cutting area.

Rapid construction system in small section TBM

This TBM auto spray is the first system of the world thatcan perform excavation and lining simultaneously.

Dust collector integrated catenary bogie

For the construction of tunnel, continueous belt conveyor system for hauling the excavated material
is the most popular method. However for the belt conveyor system requires the sufficient area for the
excavation machine equipment arrangement. Therefore for the middle sized cross section tunnel the
belt conveyor system was not adopted due to its insufficient space for site work .This excavation- dust
collector combined bogie track requires only smaller area, so that this bogie track shall be expected toincrease the belt conveyor type hauling method for the middle sized cross section tunnel construction.

Tunneling local area network system

It is a technology that considers Tunnel construction
yard as a part of network area, stabilizes the signal
condition of control data rapidly, and able to retrieve
input-output data in any work areas, either undergroundor outside the pit.

Segment position retaining system【TKS】

Reinforcing integrated segment, which is attached 3/4 slot
hinge, is applied to this shield method. According to wheeltransport system with invert gutter guide, rail facilities（such
as rail, railroad tie, etc.）will be unnecessary.
（Developed
under the corporation of Tokyo underwater road）

This is a device to support the segment ring from the outer peripheralside immediately after assembling segments by expanding inflatablebags installed in the shield tail by using compressed air. It retains thesegment position and enables to transfer the driving force of the shieldmachine to rear segments at the side of the natural ground in an
unstable condition during assembling the segments in the shield tail.

Initiatives for Achieving Environmental Safety & a Sound Material-Cycle Society

PFI & Real Estate Related Project Initiatives

Solar Power Generation Projects

PPP/PFI Projects

Throughout the period both before and after the introduction of the feed-in tariff(FIT) system, solar power generation has been gaining attention as a form of asset
management by transforming unused lands and spaces, such as idle land, building
rooftops, and more, into in-house solar generation power sites. Through the courseof our own business, Sato Kogyo established a 1.4MW mega solar power plant* in
Kikugawa City, Shizuoka Prefecture in September 2013. Following that, we, as an EPC
contractor, have utilized our expertise including the acquisition of operations rights topropose power generation systems from the planning stages to maintenance support.

PFI (Private Finance Initiative) projects are increasing in number each year
as they present themselves as an efficient method for improving social
infrastructure. Through the utilization of private funds and expertise in thedesign, construction, maintenance, and operation of public facilities, PFI
projects are expected to result in the reduction of costs and the provision ofhigh-quality services. We at Sato Kogyo have been working on PFI projects
in various fields since 2005, relatively soon after the introduction of the PFI
law, and currently have 13 completed projects to date. In recent years, wehave worked to help regional communities with school integration and district
development projects, the utilization of public lands, and the development andoperation of cultural facilities.
Our PPP (Public-Private Partnership) Projects primarily focus on the remodelingof public facilities with a focus on gymnasiums. Sato Kogyo proposed theestablishment of a sports club in a project implemented in Kitanakagusuku
Village in Okinawa. The project was successful through design and construction
in coordination with the operators, funders, and tenants. We are now planningto deploy this method to remodel gymnasiums nationwide and remodel others
to meet specific requirements, such as the new standards required of B-League(Professional Basketball) home arenas.

*Acquisition of certification for the international standard for asset management systems (ISO
55001:2014)
As an asset owner for solar power generation facilities (New Business Development Division), we
have acquired certification for the ISO 55001 international standard for asset management systems(AMS) for the planning, construction, and operation of such facilities. In the future we will strive toincrease our own business value through the application of management expertise, gained via AMS
operation, to other asset management operations.

Honganji Temple's Toyama Betsuin and SATO KOGYO Company Badge■ Reconstruction of Honganji Temple’s Toyama Betsuin and the company
badge of the SATO KOGYO Co., Ltd. ■In 1899, Toyama city suffered from a massive fire, and Nishi Honganji Temple’s Toyama
Betsuin was also set on fire.
Betsuin at the time was getting ready for the 400th anniversary of Rennyo-shounin’s death,but such was considered not possible due to the damage caused by the massive fire.
However, Sukekuro Sato, the founder of Sato Kogyo, decided to reconstruct Betsuin himself.
Supervising the reconstruction work personally, the Betsuin project was completed injust over a month. Moreover, he donated the total construction price.
The anniversary ceremony was performed successfully. The following year, Kyounyo-shounin visited Sato’s residence and placed the Japanese half-coat（haori）with
the “Sagari-fuji” symbol over Sukekuro’s shoulders to express his appreciation for
the reconstruction work.
After Sukekuro’s death, Sukekuro II added the Chinese character “佐”to the symbol andstarted using it as the company’s logo.

Sasazu Bridge and Account Book of Construction Work■ Toll bridges and the Sasazu Bridge II ■The founder, Sukekuro Sato, came up with the idea of something quite similar to thecurrent PFI（Private Finance Initiative）more than 130 years ago and built many private
toll bridges, “Chintori-bashi”, over the rivers in Hokuriku, the northern part of Japan,
which made the people’s life more convenient.
The Sasazu Bridge over the Jinzu River（Toyama pref.）was also built by Sukekuro andconverted into a toll bridge.
The first Sasazu Bridge was destroyed by runoff from melting snow and it had been considered impossible to rebuild it due to both technical and financial difficulties. However,in 1892, at the request of the prefectural government, Sukekuro attempted to rebuild thebridge using the platform method at his own expense.
This method has now evolved to become the Caisson method, and the upper part of thebridge was built in a truss shape and was the longest span in Japan at that time.

■ Yotsuya Cooporas ■In the 20’s during the Showa era, there were few quality reinforced concrete housing
complexes. Following the legal reform, we dared to enter into the private housing
complex market where no one ever did.
In 1956, we completed “Yotsuya Cooporas”, the Japan’s first condominium type high-risehousing complex, was built by a private company. This is located in the high-end residential area of Yotsuya, Tokyo, in coordination with JCB, the Japan Credit Bank.
“Cooporas” is a Japanese-born English word, meaning a cooperative house.
It is not just a housing complex but residences based on discussions with tenants, thedesigner and the contractor covering the whole process from acquisition of land, design,and construction, and incorporating the individual life styles of the tenants.
Since then, “Cooporas” has become synonymous with a housing complex.

Sakuroudani Lodging and Snap shot when Kurobe Tunnel was bored through■ Kurobe Tunnel ■Kurobe Tunnel in the 4th construction area of the No.4 Kurobe River power station.
At the site, which is an important transport route, large-size equipment such as power
plant equipment and hydraulic steel pipes had to be sent from the dam to the underground power station approximately 10 km downstream, and Sato Kogyo was in chargeof this area of 6,666 m, including two-thirds of the downstream area (and the digging
work for an area of 1,150 m).
Construction started in August 1956.
The mouth of the Kurobe Tunnel was located in the Sakurou Valley about 600 m above
the Sennin Valley where the base camp was located.
Materials and food had to be sent up the sheer cliff by climbers until the tramway between the two points was constructed.
In order to maintain the delivery time, the work had to continue during the winter.
In December 1956, full-face excavation was carried out and on January 23, 1959, We
established a Japanese digging record of 25.1 m/day.
The tunnel broke through on February 8, and the center point difference was only 2.3 cm.
■ Benjamin Sheares Bridge ■First long bridge in Singapore connecting Changi Airport and downtown.
For this project according to the international package deal tender system consisting of
the survey, design and construction, our bridge plan, using mainly pre-stressed concrete,
was selected.
Construction started in January 1977 and was completed in September 1981.
In memory of the President Benjamin Sheares, who died during his period of service andbefore the completion, the bridge was named the “Benjamin Sheares Bridge”.
A 5 dollar coin and 50 dollar note were issued to mark the completion. The bridge has
become well-known as a national symbol worldwide.
The Benjamin Sheares Bridge was praised for its construction technique and aesthetic
design and won the Tanaka prize awarded by the Society of Civil Engineering in 1981.
