    Notes and specifications on reinforced concrete technical drawings!

    Could you mention a list with all the necessary notes and specifications that a reinforced concrete technical drawing should always have?

    eg Strength Class: C30/37 etc

    I will try to update the first post of this thread whenever a new comment is posted!

    Thanks in advance,
    Ion

    GENERAL NOTES
    The contractor shall check and verify all dimensions, notes and conditions on site before any construction work is started. All discrepancies shall be reported to the architect and structural engineer. Discrepancies shall be brought to the attention of the architect / structural engineer before proceeding with the work.
    CONCRETE e.g.
    All concrete mixes shall be in accordance with EN 206-1
    Compressive strength class C35/45
    Exposure class XS2
    Maximum nominal upper aggregate size (Dmax) 20mm
    Chloride content class Cl 0.20
    Density class (light/heavy-weight concrete) N/A
    Consistence Class

    I have drawing GENERAL NOTES that I use for most projects. Is there a manner that I can attach a *.txt file to a message? Else I can attach them as several messages.

    ConcNotes121226.doc

    I've renamed it a *.doc file to avoid the 19K limit for *.txt files... format should be as *.txt... We'll see if this works...

    The front end of the file is a listing of the various parts of my general notes... I edit them as I need them for a project.

    References are to Canadian codes and info in square brackets indicates a choice. Some notes have Imperial as well as metric info and the files are modified as they are used with a project. Feel free to use and/or modify as needed.

    By the way is there any good book or publication (except for EN 206-1...) about RC specifications for ordinary structures according to Eurocodes?

    EN 1992-1-1:

    1.2.2 Other reference standards

    EN1997: Geotechnical design
    EN 197-1: Cement: Composition, specification and conformity criteria for common
    cements
    EN 206-1: Concrete: Specification, performance, production and conformity
    EN 12390: Testing hardened concrete
    EN 10080: Steel for the reinforcement of concrete
    EN 10138: Prestressing steels
    EN ISO 17760: Permitted welding process for reinforcement
    ENV 13670: Execution of concrete structures
    EN 13791: Testing concrete
    EN ISO 15630 Steel for the reinforcement and prestressing of concrete: Test methods
    I always add a note that if something on the drawing is not clear the subcontractor should contact the designer (me). Not exactly a RC note, but it's very useful.

    I don't think you should put the W/C ratio. It is already in exposure class.
