Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating accurate interpretation of work instructions and resource requirements from given information such as site plans or method statements.
- Credit should be given when the candidate effectively communicates and sequences operations with others, ensuring coordination with the demolition team and other trades.
- Assessors must verify that the candidate consistently complies with current health and safety legislation, including COSHH, RIDDOR, and PUWER, during plant operations.
- The candidate must demonstrate correct selection and inspection of resources, including PPE and plant attachments, prior to use.
- Evidence of proactive measures to minimise damage, such as using protective barriers or dust suppression, should be awarded high marks.
- Completion of work within the allocated timeframe, evidenced by signed timesheets or progress reports, is a key assessment criterion.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always cross-reference the project specification and risk assessments before starting any task; your assessor will look for this in your evidence.
- 💡Maintain a comprehensive log of daily plant checks and maintenance to demonstrate compliance with health and safety.
- 💡Use clear communication methods, such as radio protocols, and record coordination meetings with colleagues to provide evidence of effective teamwork.
- 💡Photograph or document the condition of the work area before and after operations to prove minimal impact and adherence to time constraints.
- 💡Prepare a narrative or reflective account explaining how you selected resources and managed time to meet the contract specification.
- 💡Always quote specific regulations (e.g., 'under CDM 2015, the principal contractor must...') to show depth of knowledge.
- 💡Use technical terms like 'deliberate collapse', 'progressive demolition', and 'exclusion zone' accurately.
- 💡In risk assessment questions, always state the hazard, risk, and control measure in a structured format.
Common Mistakes
Common errors to avoid in your coursework
- Misinterpreting site markings or exclusion zones leading to incorrect plant positioning.
- Failing to conduct pre-start checks on the rig, resulting in equipment malfunction or safety breaches.
- Neglecting to coordinate with other operatives, causing clashes in workflow or unsafe overlaps.
- Incorrectly processing materials, such as mixing contaminated waste, violating site waste management plans.
- Overlooking the need for continuous monitoring of surrounding structures, leading to inadvertent damage.
- Misconception: Demolition is just knocking things down. Correction: It requires detailed planning, structural analysis, and strict safety protocols.
- Misconception: Asbestos removal is part of standard demolition. Correction: Asbestos must be removed by licensed specialists before demolition begins.
- Misconception: Any excavator can be used for demolition. Correction: High-reach excavators with specific attachments are required for tall structures.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A demolition contractor must remove a 10m high brick chimney. Calculate the safe working distance for a 360° exclusion zone if the chimney is 2m wide at the base. Assume a 1:1 height-to-fall ratio.
- 1.Step 1: Height of chimney = 10m, width = 2m.
- 2.Step 2: Fall distance = height × 1 = 10m.
- 3.Step 3: Exclusion zone radius = fall distance + half width = 10m + 1m = 11m.
- 4.Step 4: Safe working distance = 11m from base.
Question: Describe the sequence for demolishing a reinforced concrete frame building using a high-reach excavator.
- 1.Step 1: Isolate and disconnect all utilities.
- 2.Step 2: Remove non-structural elements (cladding, windows).
- 3.Step 3: Demolish top-down, starting with roof slab.
- 4.Step 4: Cut columns at base, pull with excavator, ensure controlled collapse.
- 5.Step 5: Manage debris and dust suppression continuously.
