INFORMATION ABOUT ELALAN CONSTRUCTION COMPANY
EL-ALAN Construction Company (Nigeria) Limited was founded in April 1982 as
a private limited liability company and today is one of the fastest growing and
most dynamic construction and civil engineering companies in Nigeria.
For over three decades EL-ALAN has delivered high quality integrated
construction solutions. Their initial focus was renovation and sub-contract work
through which they quickly gained a name for themselves. Their success and
reputation today are built on the consistent delivery of quality, speed,
efficiency and overall client satisfaction.
They remain focused on building long lasting relationships by consistently
delivering a world class performance. Their mission statement:
Exceeding our client’s expectation through our passion for quality, our quest for
innovation and our commitment to delivery.
PARTICIPATION AND WORK DONE
Civil engineering is a professional engineering discipline that deals with the
design, construction, and maintenance of the physical and naturally built
environment including works like roads, bridges, canals, dams, and buildings.
During my short stay with EL-ALAN construction company I was opportuned to
work and be part of the construction of a drink (chivita) factory. The major works
carried out during the factory construction included; site surveying, casting of
concrete slab, steel works (steel reinforcement), road construction, excavation, etc.
PARTICIPATION AND WORK DONE
• SLAB PREPARATION
A concrete slab is a common structural element of modern buildings.
Horizontal slabs of steel reinforce concrete, typically between 4 and 20
inches (100 and 500 millimeters) thick, are most often used to
construct floors and ceilings, while thinner slabs are also used for
exterior paving, sometimes these thinner slabs, ranging from 2
inches(51mm) to 6 inches(150mm) thick, are called mud slabs,
particularly when used under the main floor slabs or in crawl spaces.
The horizontal slabs of steel reinforce concrete was used in the
construction of the factory.
PARTICIPATION/WORK DONE
PREPARATION OF A HORIZONTAL SLAB OF STEEL REINFORCEMENT
The type of steel bars used to form the reinforcement for a horizontal floor depends
on the clients demand. The size of steel bar used in the site of my industrial training
varied between 10 to 12 mm.
The site engineer is to supervise the contractors (iron benders) during the formation
of the steel reinforcement.
PARTICIPATION AND WORK DONE
The pictures below shows the preparation of horizontal steel reinforcement with 12 mm
thick steel bars.

PARTICIPATION AND WORK DONE
CASTING OF SLAB WITH CONCRETE
The process of casting involves the pouring of concrete on the particular area
necessary. Casting is done with a material known as concrete.
Concrete is a composite material composed of coarse aggregate bonded together
with a fluid cement that hardens over time. Most concretes used are lime-based
concretes such as Portland cement concrete or concretes made with other
hydraulic cements, such as ciment fondu. However, asphalt concrete, which is
frequently used for road surfaces, is also a type of concrete, where the cement
material is bitumen, and polymer concretes are sometimes used where the
cementing material is a polymer.

PARTICIPATION AND WORK DONE
.EXPANSION JOINTS
An expansion joint is an assembly designed to safely absorb heat-induced
expansion and contraction of construction materials, to absorb vibration, to hold
part together, or to allow movement due to ground settlement or earthquakes.
PARTICIPATION AND WORK DONE
.EXCAVATION
Excavation is the process of moving earth, rocks or other materials with tools,
equipment or explosives. It includes earthwork, trenching, wall shaft, tunneling and
underground.
Excavation is used in the construction site to create building foundation, reservoirs,
roads and gutters or drainages. Before any excavation is carried out on site the
levelling instrument and staff must be used go give the correct level of excavation
with respect to the drawing given.
The mechanical equipment used to excavate is called an Excavator.

.LEVELLING INSTRUMENT AND STAFF
The levelling instrument is an optical instrument used to establish and
verify points in the same horizontal plane.
PARTICIPATION AND WORK DONE
.CONCERTE MIXER TRUCK
This is a device that homogeneously combines cement, aggregate and water to
form concrete.
PARTICIPATION AND WORK DONE
.CONCRETE PUMP
A concrete pump is a machine used for transferring liquid concrete by pumping.
PARTICIPATION AND WORK DONE
.CONCRETE VIBRATOR
The concrete vibrator is a construction tool used to ensure that the pour is free of
air bubbles and are even.
PARTICIPATION AND WORK DONE
.CONCRETE POWER TROWEL
The concrete power trowel is a construction equipment used to apply a smooth
finish to concrete slab.
PARTICIPATION AND WORK DONE
.SOIL COMPACTOR
A soil compactor is a construction machinery used to compress different types of
soil and gravel.
EXPERIENCE GAINED
Over the years, the demand for shelter has greatly increased. As a result, civil
engineers are faced with the responsibility of building safe and durable structures
to meet individual demands of client. The Students’ Industrial Work Experience
Scheme (SIWES) creates a platform for young and growing engineers to interact,
learn and be groomed by professional engineers in order to ensure the continuous
construction of safe structures.
I gained experience in the use of the Levelling Instrument which was one of the
most important on site and the most important surveying instrument.
I also gained experience in the supervision of basic site construction works.
CHALLENGES FACED
The major challenge I encountered during my industrial training was down to lack
to practical knowledge of the things I was already taught in the class. As upcoming
civil engineers we learn a lot in class, but it is not enough as most students are
denied adequate practical of class activities.
For example, during the early period of my training I realised that most of the
work done and equipment used were things I was already familiar with when it
came to class activities, but I have no practical knowledge of. In the case of the
levelling instrument I could define and write an essay on the levelling instrument
but I had challenges operating the instrument during the early period of my
training.
