What is the purpose of estimation in construction measurement?

• To ensure accurate measurements

• To increase cost implications

• To quickly give a guide to quantities

• To remove the need for accuracy

What are the dangers of estimation in construction measurement?

• Overestimating only

• Underestimating only

• Neither under- nor overestimating

• Both under- and overestimating

In the given scenario, what would have been the consequence of underestimating the floor area?

• The job would have been completed with extra materials

• The job would have been delayed due to insufficient materials

• The customer would have been satisfied with the outcome

• The profit would have been maximized

Why are carbon emissions a concern in the construction industry?

• They have no impact on the environment

• They are not affected by human activities

• They are easily absorbed by nature

• They contribute to global warming

What is the purpose of measuring and regulating CO2 in buildings?

• To remove the need for infrared CO2 sensors

• To encourage the use of fossil fuels

• To reduce the energy usage

• To increase the operational carbon footprint

What is the 'embodied carbon' associated with in the construction industry?

• The regulation of CO2 emissions

• The materials of which a building is made

• The operational generation of CO2

• The quality of indoor air

How can the construction industry reduce the generation of CO2?

• By using more fossil fuels

• By removing insulation from buildings

• By increasing the energy usage

• By using better insulation and more efficient heating systems
