دبي لحلول االستشعار To whom it may concern:

DuSense was established in Dubai July 2014 by Mike Shaw to provide Middle East Indus-

try with advanced technical support in areas of Sensors and Instrumentation Systems that

are used in the Civil, Construction and Marine markets.

DuSense also represents a distinguished group of international business’s who’s activities

have good synergy to our own.

You are introduced to us as a distinguished Ground Engineering and Foundation company

which is interested to have Bi-Directional Static Load Test service provided to you.

DuSense are experts in Pile Testing and we’re the Middle East representatives of FES- Ou-

gang Technology who collaborate with the China Academy of Building Research (CABR),

CABR was established in 1953, it is the top-rated certified institution in the building indus-

try in China. CABR provides our global customers with bi-directional load test service in-

cluding installation of load cells, field data collection & analysis, and test report preparation

by working with our partner Hangzhou Ougan Technology Company Limited, a leading

manufacturer of load cells specially applied to bi-directional load tests.

Starting in the year 2005, we have tested more than two thousand piles in and out of China,

by applying our own patented load cells.

This profile contains key pre-qualification data upon the capabilities and history of our per-

formance with the provision of Bi-Directional Static Load Testing, it contains certifications,

project references, and some financial data about our Principle the China Academy of

Building Research who would be the ultimate verification authority of any report issued by

FES-Ougan Technology on our behalf.

China Academy of Building Research

Founded in 1953, China Academy of Building Research (CABR) is the

largest and most diverse research institution in building industry in China.

It used to be affiliated to the Ministry of Construction (MOC). Since 1 October

2000, it transferred from the public institution into a technology-based enter-

prise, affiliated to the State-owned Assets Supervision and Administration

Commission of the State Council (SASAC).

As the largest comprehensive research and development institute in the

building industry in China, CABR is responsible for the development and man-

agement of the major engineering construction and product standards of China.

It exercises quality supervisions and tests on engineering construction, air con-

ditioning equipment, solar water heater, elevator and chemical building materi-

als so as to promote the scientific advancement of the construction industry, to

push forward the standardization of the engineering construction, to enhance

construction quality management, and to make active contributions to the de-

velopment of construction industry in China.

CABR has 14 research institutes (centers) and 77 laboratories, covering 70

research fields of building structure, foundation, earthquake engineering, built

environment and energy efficiency, residential building system and product, in-

telligent building, building engineering software, construction mechanization,

building fire prevention, construction technology, building materials and so on.

For Bi-Directional static load test service, CABR provide by working

with Hangzhou Ougan Technology company Ltd, a leading manufacturer of

load cells specially applied to bi-directional load tests.


As a partner of CABR, OUGAN Technology has four business sectors:

Bi-directional static load test equipment manufacture and service;

Piling equipment, tools & accessories export;

TEI Rock Drills exclusive distributor in China;

Rent of piling rigs, service and parts supply in China;

Bi-Directional Static Load Test Equipment& Service

Headquartered in Hangzhou, Zhejiang of China, OUGAN is specialized in

the design and manufacture of Bi-directional static loading test (BDSL) equip-

ment.

Starting in the year 2005, we have tested more than two thousand piles in

and out of China with our own patented super cells by working with CABR.

We provide complete service including super cell manufacture, cell installa-

tion, field data collection & analysis, and test report preparation.

OUGAN was invited by National Center For Quality Supervision And Test

Of Building Engineering - the top inspection institute of construction system

in China, to participate in research of BDSLT special project as the equipment

and technology supplier in 2012. This demonstrates how OUGAN is involved

in the further regulation and promotion of BDSLT applications for inspection

and testing of pile foundations.

First Joint-Venture was established in Singapore in year 2014 to provide

bi-directional static load test service in Southeast Asia. And the Joint-Venture

for Middle-East Market is planned for establishment in Dubai by 2015.

Hangzhou Ougan Technology Company LTD


Unlike conventional cells that virtually are combination of hydraulic

cylinders, OUGAN Super-cells consist of one or multiple inflatable jacks

(Super-jacks) that produce large load. The patented Super-jacks adopt

special sealing technology, and are made with large loading area, low

original height, light weight, and excellent loading performance. Due to

the large loading area, no high pressure is needed to produce high load.

Usually, the max hydraulic pressure to do bi-directional loading test with

super-cells is lower than 30Mpa. This dramatically reduces the risk of hy-

draulic failure. The Super-cells may be built in various shapes, depending

on pile diameters and test purposes.

Combined Super Cell


Each super-jack is tested and calibrated before assembly. The loading

pressure is determined by calibration result on linear relation between pres-

sure and load.

Calibration process Calibration Certificate

Telltale wire is utilized to measure displacement. Tied at suitable position

of reinforcement cage, the telltale wire transfers the displacement all the way

to the other end on ground. The telltale wire is shielded to be separated from

concrete, and it’s straightened by a steel block hung on the other end. A

measurement base is set up to record the displacement.
