WHAT ARE THE ORIGINS OF BUILDING CONTROL? The great plague of 1665 The great fire of London 1666 The industrial revolution The Ronan Point

WHAT CHANGES AFFECT CONSTRUCTION OF BUILDINGS? Government Policy changes Local Building by-laws National standards

WHAT IS THE PURPOSE OF BUILDING CONTROL? Ensure standards are followed for the safety of

the occupants. Safety and Hygiene e.g. fire safety, structural,

safety, ventilation, waste disposal Improvement of energy efficiency as in Part L

of the Building Regulations which is concerned with conservation of fuel and power

Reduction in water wastage –Part H of the Building Regulations makes provision for separate systems of drainage: one foul and the other for rainwater or surface run- off . Only foul water is sent for treatment saving energy in the process

LIST DOWN THE PURPOSE OF BUILDING CONTROL Ensure standards Building regulations are applied to

produce good buildings and ensure safety and security of the occupants who dwell in such buildings.

Any changes in government policy and any new technological developments cause changes and regulations are updated through changes in the Approved Documents

LIST DOWN THE PURPOSE OF BUILDING CONTROL Safety and Hygiene Safety is paramount to occupants. Included in

the documents are the following: Fire safety e.g. fire extinguisher, fire exits, fire

blankets, fire rated materials, fire alarms, sprinklers, smoke detectors

Structural safety – to check settlements and collapse

Contamination – the care of toxic substances Ventilation – to provide clean air Hygiene – waste disposal and cleanliness Drainage and waste disposal Boilers- regulation of heating

MENTION FOUR FIRE RESISTANT MATERIALS USED IN CONSTRUCTION plasterboard concrete blockwork intumescent paint

PLASTERBOARD

CONCRETE

INTUMESCENT PAINT

MENTION FIVE FIRE RESISTANT TECHNIQUES Fire-resistant techniques: fire compartments and fire barriers

(walls, separating floors, door closes, fire-resistant doors)

fire escapes refuge areas cavity fire barriers fire alarm systems, smoke detection and

sprinkler system

WHAT ARE FIRE COMPARTMENTS? These are divisions into sections that

are made in a building so that fire in one compartment will not affect the others.

The compartments are separated by features known as fire barriers

GIVE EXAMPLES OF FIRE BARRIERS Fire walls Separating floors made of concrete Door closers which stop doors from being

left ajar Fire resistant doors that are steel painted

with intumescent paint

Intumescent paint- paint that swells when heated. When it is heated up by fire it expands and become thicker layer on top of the painted material. THIS SLOWS TRANSFER OF HEAT TO THE PAINTED MATERIAL

DO THE LAYOUT PROBLEM Annotate the given drawing with fire

extinguishers (FE) and fire escape route (FER)

LIST DOWN THE PURPOSE OF BUILDING CONTROL Improve energy efficiency Part L of the Building Regulations is concerned

with the conservation of fuel and power. It is split into 4 parts :

New builds – domestic , commercial Refurbishments/extensions – domestic and

commercial Part L covers the following: U-values and calculations Air permeability Limiting heat loss Limiting air conditioning

LIST DOWN THE PURPOSE OF BUILDING CONTROL Reduction in water wastage Part H of the Building Regulations makes

provision for separate systems of drainage: one foul and the other for rainwater. By having separate systems not all of the waste water needs to be treated therefore saves energy and water in the process.
