    Default Electrical and Mechanical Drawing Scale Standards

    Registered forum members do not see this ad.

    Does anyone know if there is a document of industry standards of producing M&E drawings.
    I have worked for a few companies and was told that electrical drawings are 1:100 scale and Mechanical 1:50 scale.
    However i am now with a company who say both Mech and Elec drawings should be 1:50.
    I was always told to try use A1 drawings where possible.
    I just dont see the point of having an Electrical drawing on A0 sheet with 12 sockets and a Dist board or have containment on A0 when you can see perfectly well on A1
    I know it depends on project some might have lots of fittings and of course you will then need to use 1:50.
    But i am talking about an average residential project.
    Can anyone advise.

    There should be a BS British Standard for drafting may be old but its recommendations should still be applicable.
