Buildings other than dwelling houses, includes classifications of purpose groups for
which buildings or compartments of a building are intended to be used.
It defines industrial purposes as:
Factories and other premises used for manufacturing, altering, repairing, cleaning, washing,
breaking-up, adapting or processing any article; generating power or slaughtering livestock.
Which is one of factory in Ethiopia which is produce cable is BMET. “BMET energy
telecom industry and trade PLC” is the biggest capacity electrical cable factory investment in
Ethiopia. BMET can manufacture all types of electrical cables including telecom cable and fiber
cables with the latest technology.

3. The project aims to provide calibration services and to improve the high voltage laboratory
infrastructure of BMET energy telecom industry and trade LLC, a company operating in
Ethiopia.
The industry can be see
13/08/2009ecat the time of 3:30am
and the external entrance of factory is
not bad but it is not empress and
emphasize. The eternal landscape is so
match better it is green and the road is
normally nice and the external
circulation is so good.The BMET energy telecom industry and trade PLC factory
is found on the main road and the product can be transported is good situation
and access.
The BMET energy telecom industry and trade PLC main factory office is found at
the front of the factory it is G+2 building and the function of this building can be
used to receptionof BMET energy telecom industry and trade PLC can be found
and the other two side can be found the office purpose and at the first floor is
cafeteria. The building to match batter appearance to the external and internal
good.

At the back BMET energy telecom industry and trade PLC factory is the back of office building.
The office building can be see the factory
works and workers can be seen. The cable
industry or factory is normally set the
machine and the working space not bad.
The machine spare parts can be set in on
order and proper pace any person can be
found at the right pace.
But the working space can be more product
set in the working space floors and the row
material can be set on the floor working
place it is the bad view of the BMET energy telecom industry and trade PLC factory this is the
barrier of the industry.

12. The machine order and the
building is functional to set
properly to in the BMET
energy telecom industry
and trade PLC factory. And
the condition of the factory
purpose is and the machine
set all on the floor and the
row material is set on the
factory place or working
space that is the barrier of
BMET energy telecom
industry and trade PLC
factory workers.
The row material of BMET
energy telecom industry
and trade PLC factory is
found in Ethiopia
telecom, Ethiopia
Electric Corporation and
other facility. At the
back of the factory this
pace can be danger
place to worker but the
material is manly found
and place to reuse the
product plaice.
At the all BEMT
energy industrial
building is show the all the internal control room and office and the internal laboratory technical
staff room and workers to be provides this is the good view and good industrial design to be
seen.

13. I have to see the grate structural systems
to show the BMET energy all structural
system is steel structure and the all steel
columns. The roof structure is entered the
natural light to the internal working space
or place and the artificial lights can be set
in the proper orders this is the greet view of
and the good structural system.
The BMET energy building floor is almost
cracked and think this is happened the
building is worked at the fast binging of the
industrial purpose functionality at this
action the concrete structure can be support the all machinery’s and the working process or
workers on this proses the industrial
floors can be cracking in the all factorial
space and mechanical place. The
cracking is happed mostly at the place of
structural columns and machine seating
places.
The generator room is set at the back
space of the industrial or the factory that
is startup to the removal of electric
powers because the machines can be
damage at stopping work in the powers of electric.
The good circulation of the factory and the working space and the worker can move at frilly
circulated and movements of work. And the
working space is u shape and the machine
cab be set in the u plan order.
There are to department of cable fabrication
process:
- Communication cable
- Power cable
