CSCS Environmental Awareness 5 — Questions and Answers
Question 1: What is a 'protected species' in the context of UK/US environmental construction law?
- A plant or animal whose habitat and individuals are legally protected from harm or disturbance (Correct answer)
- A species of tree that must be preserved on site regardless of the project design
- Any domestic animal found living near a construction site
- A plant variety approved for use in site landscaping schemes
Correct answer: A plant or animal whose habitat and individuals are legally protected from harm or disturbance
Protected species (e.g., bats, certain salamanders, migratory birds) have legal protections that make it an offence to disturb them or their habitats without a licence.
Question 2: What does a 'brown field' site refer to in construction and environmental terms?
- Previously developed land that may be contaminated and requires investigation before reuse (Correct answer)
- Agricultural land being converted to residential use for the first time
- Any site where soil has turned brown due to drought conditions
- A site located in a rural area away from existing infrastructure
Correct answer: Previously developed land that may be contaminated and requires investigation before reuse
Brownfield land has previously been developed or industrially used and often requires contamination assessment and remediation before redevelopment.
Question 3: Which of the following best reduces dust pollution from earthworks on a construction site?
- Applying water suppression to exposed surfaces and unpaved haul roads (Correct answer)
- Working only during windy conditions to disperse dust quickly
- Increasing the speed of site vehicles to reduce travel time
- Covering all machinery with plastic sheets when not in use
Correct answer: Applying water suppression to exposed surfaces and unpaved haul roads
Water suppression damps down exposed soil and haul roads, preventing fine particles from becoming airborne and affecting air quality off site.
Question 4: What is the environmental purpose of a 'wheel wash' at the exit of a construction site?
- To prevent mud and sediment from being tracked onto public roads and into drainage systems (Correct answer)
- To clean construction vehicles before they enter the site each morning
- To provide a water source for dust suppression during hot weather
- To remove chemical residues from vehicle tyres before they reach the fuel station
Correct answer: To prevent mud and sediment from being tracked onto public roads and into drainage systems
Wheel wash facilities remove mud from vehicle tyres before they leave site, preventing soil and sediment from entering public roads and drains.
Question 5: Why should tree root protection zones be established before construction begins near existing trees?
- To prevent compaction and physical damage to roots that could kill the tree during construction (Correct answer)
- To provide a safe exclusion zone for workers using heavy machinery
- To mark where temporary site accommodation can be placed
- To indicate areas where underground services are most likely to be found
Correct answer: To prevent compaction and physical damage to roots that could kill the tree during construction
Root protection zones safeguard the critical root area from soil compaction and physical cutting, which can fatally damage or kill trees.
Question 6: What does the 'polluter pays' principle mean in environmental law?
- The party responsible for causing environmental damage must bear the cost of remediation (Correct answer)
- Construction companies pay a fixed environmental levy on every project
- Contractors are fined for every skip of waste sent to landfill
- Site workers personally pay fines for any environmental incidents they report
Correct answer: The party responsible for causing environmental damage must bear the cost of remediation
The polluter pays principle holds that whoever causes environmental contamination or damage is legally and financially responsible for cleaning it up.
Question 7: Which of the following is the correct action if construction activity disturbs a bat roost?
- Stop work immediately, protect the area, and contact a licensed bat ecologist before proceeding (Correct answer)
- Continue work carefully and report the disturbance at the end of the day
- Remove the bats humanely and relocate them to a nearby woodland
- Seal the roost entrance to prevent bats from returning during construction
Correct answer: Stop work immediately, protect the area, and contact a licensed bat ecologist before proceeding
Bats and their roosts are fully protected by law; any disturbance must be halted immediately and a licensed ecologist must advise on how to proceed.
