Welfare Facilities and Environmental Legislation Flashcards

What is the purpose of a site environmental walkover before construction begins?

Answer: To identify environmental features and receptors (watercourses, sensitive habitats, protected species, neighbouring residents) that may be affected by construction and to inform the CEMP and risk assessment

A pre-construction environmental walkover identifies: watercourses, drainage paths, ecological features, neighbouring sensitive receptors (schools, hospitals, residential areas), and any existing contamination. This information informs the CEMP and the specific environmental controls needed during construction.

Under the Contaminated Land Regime, a site manager working on a brownfield site suspects they have encountered contaminated soil. What should they do?

Answer: Stop work in the affected area, prevent spread of contaminated material, notify the project manager and environmental manager, and ensure the material is assessed by a competent environmental specialist before work resumes

Encountering unexpected contamination requires: stopping work in the affected area, preventing spread, notifying the project team and environmental specialist, and not resuming until the material is assessed and appropriate controls are in place. Unexpected contamination can also trigger planning condition requirements.

A construction project must manage its carbon footprint. What is a 'scope 3' emission in the context of construction carbon reporting?

Answer: Indirect emissions associated with the supply chain — including extraction, manufacturing, and transport of construction materials and the activities of subcontractors

In the GHG Protocol framework, Scope 1 = direct emissions (site plant, vehicles), Scope 2 = indirect emissions from purchased energy (electricity, heat), and Scope 3 = all other indirect emissions in the supply chain and value chain — including embodied carbon in materials, subcontractor emissions, and waste disposal.

What does the circular economy principle mean for construction waste management?

Answer: Designing out waste at the start, reusing materials on site and across projects, recycling waste generated, and recovering energy from what cannot be recycled — minimising disposal and keeping materials in productive use for as long as possible

The circular economy applies the principle that materials should remain in productive use for as long as possible — through design for disassembly, reuse of components and materials, and recycling of waste — reducing demand for virgin resources and minimising landfill.

Which of the following is a 'protected species survey' that may be required before vegetation clearance or demolition on a construction site?

Answer: A bat survey (using bat detector equipment and transect surveys) carried out by a licensed bat surveyor before any works that could affect potential roosting sites

Bat surveys must be carried out by licensed surveyors before any works (demolition, roof works, tree felling) that could affect potential bat roost features. Surveys must be conducted during appropriate seasons (typically April–October) and may require multiple visits. Results inform any mitigation and licensing requirements.

The Environmental Permit for a water discharge activity from a construction site typically requires monitoring of the discharge. What parameter is commonly monitored for dewatering discharges?

Answer: Suspended solids (turbidity), pH, and sometimes hydrocarbon content — to confirm the discharge does not exceed permit conditions and does not cause visible pollution or harm to the receiving watercourse

Dewatering discharges are monitored for suspended solids (turbidity is a proxy), pH (groundwater can be alkaline if passing through concrete), and hydrocarbons (in case of fuel contamination). Permit conditions specify the monitoring parameters and frequency, and results must be recorded.
