INTRODUCTIONThe industrial revolution led to a rapid increase in
the number of industries in the world. This led to increase in employment rate and gross
domestic product (GDP).Countries like China are competitors with almost
every industry in the world, because of the high level of industrialization.
INTRODUCTION TO VIRGOAn engineering firm with about
3oo employees, owned by a sole proprietor(Chief Oyegunle Oyegbade).
Sales, supply and installation of power diesel generators.
Construction of various infrastructures (buildings).
Manufacture and supply of high tension pole.
Fabrication of metals.
WHAT WE DO AT VIRGO
Power diesel generators
Concrete high tension poles
Block making
POWER DIESEL GENERATORSThey are used in the
fields of construction, communication, banking business, mining, leasing industry and other special sites.
Continuous service.
Standby service.
•Emergency service.Picture

CONCRETE HIGH TENSION (HT) POLES.They were developed to meet the expanding need of a
supporting structure for; street, highway and area lighting, athletic lighting, signs, overhead power distribution and power transmission as well as power substations and traffic signals.
BLOCK MAKING
The block making process shown has five major steps
These steps are outlined in the process diagram shown.
It is a cycle that works for every type of block or brick/ interlocking stones, irrespective of the size and density.
Measuring of sand or
aggregate
Sieving of sand/aggregate and measuring
again
Mixing of aggregate/sand + cement + water
Pouring of output into brick/block
making machine.
Bricks/ blocks of different sizes
come out.

TURN KEY PLANTS FOR A BLOCK INDUSTRY
THE NEED: It is a long way from mixing the raw materials to the finished block.
Each part of the plant has been matched to the other parts containing optimized processes within those parts.
Forward looking planning, often referred to as “begin with the end in mind” is a fundamental requirement for a complete efficient production facility.
The different required materials go from the aggregate silos via transport systems to the dosing and mixing plant.
The concrete is then conveyed to the block making machine.
This then compacts the concrete in a mould using a combination of pressure and vibration
TURN KEY PLANTS CONTINUED. The fresh concrete products go then to product pallets via a
conveying system, then pass through an optional quality assurance system, onto the curing chamber.
After the curing process, the products are combined to form a pack of blocks using a Cuboter and are prepared for unloading (e.g. by forklift).

SAFETY FIRST. Safety has to do with the worker, work piece and machines being free of
accidents or injuries. Some safety precautions are:
Flowing or loose gown must not be worn.
Correct shoes must be worn such as those that will cover the toes against the likelihood of tools, work piece, or machine parts dropping.
Articles like ear-rings, wrist watches, should be removed when working in the workshop as these are likely to be caught by moving parts of the machines.
Physical defects must be well tested and put right before any worker is allowed to work in the workshop.
The surrounding of the workshop must be clean, well ventilated, spacious, and should generally conform with factory regulations.
RECOMMENDATIONSAdequate supervision of students should be
done, to know if they are really learning.
The centre should also try and help out with accommodation issue that may arise during the course of the programme , by liaising with the school management to reduce the stress students pass through during this period, because many do miss out on real opportunities (going out with their boss on a capital project) while working out their accommodation.
