        NOTICE TO SPECIFICATION WRITERS
        The Schools Facilities Standard (SFS) Specification Standard text for
        CARPET consists of all the specification requirements for use in school
        building project specifications.

        The text is based           on     the   NATSPEC       Building   Professional
        Template/Worksection.

        The Specification for the Carpet section is written “in full” and there is
        no need to refer to NATSPEC.

        If another version of NATSPEC is being used the format and numbering must
        be adapted to suit.

        Refer to NATSPEC for the content and NATSPEC Commentary about their
        usage.

        Select only those Clauses that are relevant and do not amend any Clause
        unless it is necessary to suit a particular requirement of the project. To gain
        maximum benefit from NATSPEC the temptation to make minor alterations to
        clauses without changing the intent must be resisted. Real benefits can be
        gained through a standardised way of saying the same thing in each project.

        The Guide Notes and amendment dates are typed in “Hidden Text”. If the
        Guide Notes and/or amendment dates are not required when printing, select
        the “Option” choice from File/Print menu and deactivate the “Hidden Text”
        printing option.

        method is used.

        Cross Joins
        Carpet in high traffic areas is to be free of cross-joins. The entire job is to be
        planned with a minimum of cross-joins, without resulting in excess wastage.
        Do not use carpet infill strips in doorways. Avoid cross-joins in doorways
        where possible, where unavoidable cross-joins occur at doorways, locate the
        joins directly below the closed doors.

        Fixing
        Gripper Strip (Carpet Gripper): Using preformed gripper strip and tackless
        edge strip. Space fixings at 150mm centres

        The gripper is to be fixed as necessary by a combination of:
