The Daily duties of a civil contractor depends on job specializations.

2. Contractors and engineers are
mostly involved in the design
and analysis of columns,
beams, and numerous other
support devices for both
building structures, and non-
building structures, such as
bridges, tunnels, and much
more.
Civil construction engineer
regularly compare the
approved building plans with
the real building to ensure that
it corresponds and also meets
the necessary building codes
that are require to ensure the
structural safety

3. The Daily duties of a civil engineer depends
on job specializations. This includes.
•Preconstruction planning
•Infrastructure maintenance
•Surveying land schematics, maps and
drafting software
•Creating Structures and systems
•Large amount of technical and computer
work
•Design Implementation

4. We can Exploit Different Types of Materials
1 Petrous or stony Materials
2. Algomerative materials
3. Concerte
4.Ceramic
Materials used in construction are those
that are employed in the edification .

5. Compact rocks: They are blocks of limestone,
marble, granite,
slate, sandstone etc
Disintegrated rocks: They are fragments of rocks
of variable size. In construction we use:
Clay: It can absorb water.
Arid or fragments of the disaggregation of rocks.
They can be sand , gravel etc
Petrous or Stony Materials

6. When They are mixed with water they turn
pasty and when they solidify they acquire
lightness
1. Lime: To obtain this material we heat
limestone.
2. Gypsum: It is mineral in powder and when
we add water to it. We use it to cover
walls or roofs. There are three types
• Black with impurities
• White without impurities
• Plaster
Algomerative Materials

7. •It is a mixture of arid, algomerants and
Water
• Regular Concrete: It includes powdered
cement mixed with water.
• Cyclopean concrete : It is made up of
cement, Water and big arid
• Reinforced Concrete: Inside of it there Is
an armor made up of steel bars can be
tense before the concrete solidifies or
after.
