Unit 103 PPT 1 -3 Recap

What is the purpose of surveying before a project starts?

• To paint site boundaries

• To determine topography and set accurate levels

• To estimate project cost

• To test soil composition

Answer explanation

Surveying before a project starts is crucial to determine topography and set accurate levels, ensuring proper planning and execution. This helps in understanding the site's physical characteristics, which is essential for project success.

Which of the following is NOT a traditional method of surveying?

• Chain surveying

• Compass surveying

• Laser scanning

• Benchmarks

Answer explanation

Laser scanning is a modern technology used for surveying, while chain surveying, compass surveying, and benchmarks are traditional methods. Therefore, laser scanning is NOT a traditional method of surveying.

What does a benchmark represent in surveying?

• A temporary fence post

• A fixed reference point for measuring heights

• A laser level reading

• A compass direction

Answer explanation

A benchmark in surveying is a fixed reference point for measuring heights, providing a stable and known elevation from which other measurements can be taken. This is essential for accurate surveying and construction.

Which instrument measures both horizontal and vertical angles accurately?

• Theodolite

• Spirit level

• Measuring tape

• Plumb line

Answer explanation

The theodolite is a precision instrument designed to measure both horizontal and vertical angles accurately, making it essential for surveying and construction. Other options do not measure angles.

Which renewable energy source uses moving water to generate power?

• Solar

• Wind

• Hydro

• Ground source

Answer explanation

Hydro energy uses moving water, typically from rivers or dams, to generate power. Unlike solar or wind energy, which rely on sunlight and air movement, hydro specifically harnesses the kinetic energy of water.

The purpose of insulation in buildings is to:

• Reduce heat loss and improve energy efficiency.

• Increase noise levels inside the building.

• Allow moisture to enter the building easily.

• Make the building structure weaker.

Answer explanation

The correct choice is to reduce heat loss and improve energy efficiency. Insulation helps maintain temperature, minimizing energy consumption and costs, while the other options are incorrect as they do not reflect the purpose of insulation.

What does the 'polluter pays policy' mean?

• A) Polluters pay to clean up their environmental damage

• B) The government pays for pollution

• C) Pollution fines are optional

• D) Builders are exempt

Answer explanation

The 'polluter pays policy' means that those who cause environmental damage are responsible for the costs of cleaning it up. Therefore, the correct choice is A) Polluters pay to clean up their environmental damage.

Which regulation protects rare plants and animals from construction impacts?

• Building Regulations

• Environmental Damage Regulations 2009

• Health and Safety Act

• Flood and Water Act

Answer explanation

The Environmental Damage Regulations 2009 specifically aim to protect rare plants and animals from the impacts of construction and other activities, making it the correct choice for this question.

What is the main responsibility of a development control officer?

• Approving building designs

• Assessing and enforcing planning applications

• Managing building materials

• Designing road layouts

Answer explanation

The main responsibility of a development control officer is assessing and enforcing planning applications, ensuring that building projects comply with local regulations and standards.

What is the first stage of applying for planning permission?

• Full planning application

• Outline planning permission

• Building control inspection

• Retrospective application

Answer explanation

The first stage of applying for planning permission is to seek Outline planning permission, which establishes whether the proposed development is acceptable in principle before submitting a Full planning application.
