This specification has been prepared to assist design professionals in the preparation of a project or office master specification used to specify modular or carpet tile flooring.
This specification section assumes the project manual will contain complete Division 1 - General Requirements sections and close coordination with it is required. If the project manual does not contain these sections, additional information should be included under appropriate articles.
This Section number (09 68 13) including Section references noted under Related Work Specified Elsewhere is based on the MasterFormat 2004 numbering system.
This specification is directed to the (General) Contractor (or Construction Manager). Where there is no General Contractor substitute the term Flooring Contractor.
Review all requirements noted herein and carefully choose those that meet project requirements. The Specifier must choose one item from a series of items surrounded with [ .. ] brackets such as [Contractor] [Construction Manager] [Consultant] and delete the remainder. Items surrounded with ( .. ) brackets are additional information / comments that should be left in the specification.
Adding or deleting items in this specification must be done with care and caution. The onus of doing so rests with the Specifier who must have a complete and thorough understanding of what is required. Where additional information must be added to this specification the Specifier must ensure that such information is not only accurate but also in accordance with NFCA requirements. Because of the above noted requirements NFCA strongly recommends that this specification be edited by a qualified specification writer (refer to Part A16 - Specification Guides, 1.02).
This specification is not set-up with auto-numbering. Any changes (additions or deletions) therefore means that the specifier will have to re-number / re-space following items to suit.
Revise header and footer to suit project requirements. As a suggestion insert project name particulars on left side of header and consultant name on bottom left and issue date on bottom right of the footer.
