| List some of the statuatory authorties that regulate demolition work? | Highway Water Sewage Electrical Telecommunications Gas Rail |
| Why are CDM regs are important to Health and Safety? | Assign job roles under CDM Assign pre contract information PCI |
| What is required in the HSE report for demolition? | High risk suveys for premature collapse Mitigation - Structural design knowledge, methods and equipment selection Structral surveys Method statements and good planning Temporary structures |
| What environmental strategies should be adopted? | Waste managment strategies in accordance with regulations, prevention of undue consumption, reuse of concrete aggreagte, reducing land fill, recylcing softstrip, roofing and ties. |
| What should all demo sites have in reference to waste managment? | Audit of potential reclaimable and recycleable materials |

| What is explosive demoltion? | Use of controlled explosives on structural elememts, causes building to fall inwards, rubble is then removed. Takes many weeks to plan, requires exclusion zone, high security, quick once plans are agreed. |
