Thermal conductivity common use in the construction and textile industries. The construction industry makes use of units such as the R-value (resistance) and the U-value (transmittance). Although related to the thermal conductivity of a material used in an insulation product, R- and U-values are dependent on the thickness of the product. Likewise the textile industry has several units including the tog and the clo which express thermal resistance of a material in a way analogous to the R-values used in the construction industry. There are a number of ways to measure thermal conductivity. Each of these is suitable for a limited range
Building and Construction Authority build up a skilled workforce, adopt more advanced construction technologies, and enhance building capability in niche areas. BCA strongly promotes the adoption of Building Information Modelling (BIM), which allows professionals to work on a building project digitally before it is built. BCA targets to get 80 per cent of the industry to use BIM widely by 2015, and is working with the public sector to take the lead in driving greater BIM adoptiont. Building and Construction Authority The Building and Construction Authority (Abbreviation: BCA; ) is a statutory board under the Ministry of National Development of the Singapore Government. It
