Unit 1 Construction Principles

A development company is building a large warehouse. The design of the warehouse

will be of a pre-fabricated structural steel frame.

The warehouse design will need to incorporate concrete paved loading bays for

heavy goods vehicles delivering materials.

Identify one property that allows the concrete to be fully compacted.

• Toughness

• Malleability

• Workability

• Hardness

The architect has calculated the loadings on the upper floor of the building.

Explain two reasons why the architect would need to consider the dead and live

loads on the upper floors of the building.

A civil engineering contractor is constructing a new railway line in an urban area.

Parts of the railway line will be at ground level with other parts carried by reinforced

concrete viaducts above the ground.

The steel used for a railway track needs to resist abrasive wear.

Identify a property that enables steel to resist abrasive wear.

• Ductility

• Hardness

• Stiffness

• Resistivity

State one cause of degradation from natural processes.

A surveyor has been asked to measure the levels of humidity in the apartments.

Identify one instrument that is used to measure humidity.

• Anemometer

• Barometer

• Hygrometer

• Thermometer

What is the process of dipping external steelwork items hot zinc

• Polyurethane Coatings

• Hot Dip Galvanising

• Zinc-Rich Coatings

• Acrylic Coatings

What is a Structural Member?

• Structural members are the elements of a building

• support load

• elements of a building or structure

• Structural members are the elements of a building or structure that help to support load

A structure should be able to?

• Be capable of carrying its own weight

• Foundations should remain stable under load

• Excessive wind forces should not cause the building to collapse

• Walls, floors and roofs should not deflect unduly when loaded

• All of the above

Identify the term used to describe the total amount of energy used to produce a

construction material.

• Kinetic energy

• Embedded energy

• Potential energy

• Passive energy

A civil engineering contractor has been commissioned to build two new access roads

to a power station.

The roads will require a number of other structures to be built, including retaining

walls and concrete bridges.

State one component of concrete.
