BS ISO 1803:1997

What is ISO 1803 - Expression of dimensional accuracy of the building about?

ISO 1803 describes the basic principles for the expression of dimensional deviation in building and defines the basic terms and definitions relating to the evaluation, specification, and verification of accuracy.

ISO 1803 is applicable to the manufacture of building components (standard or purpose made), the setting out process, erection and assembly, and the building as a whole.

Who is ISO 1803 - Expression of dimensional accuracy of the building for?

ISO 1803 on the expression of dimensional accuracy is useful for:

• Architects  
• Real estate developers  
• Civil engineers  
• Contractor
• Builders
• Construction industries 

Why should you use ISO 1803 - Expression of dimensional accuracy of the building?

Dimension is the extent in a given direction or along a given line or a given angle

ISO 1803 assists you with:

• The expected dimensional variability that is both assessed and allowed for in design (using the probability concept if desired)
• The dimensional needs of joints that are compared with expected variabilities so that functionally satisfactory joints can be achieved
• The accuracy requirements, that reflect the needs of the design may be clearly specified for all stages of construction
• The sizes and shapes of components, in in-situ work and buildings, that are subjected to the necessary dimensional checks and compliance control procedures during manufacture, setting out, and erection

Overall, ISO 1803 helps you with the dimensions and dimensional accuracy of the building.
