Building services account for around half the value of construction projects but get little of the influence in how they are designed and constructed (until it is too late). The role of building services is often undervalued and therefore products are selected with price in mind rather than the delivery of a quality building. The […]

Understanding compartmentation One fundamental aspect of fire safety is compartmentation which is aimed at limiting the spread of fire within a building.
