LANL MASTER SPECIFICATION

This template must be edited for each project.  In doing so, specifier
must add job-specific requirements.  Brackets are used in the text to
indicate designer choices or locations where text must be supplied by
the designer.  Once the choice is made or text supplied, remove the
brackets.  The specifications must also be edited to delete
specification requirements for processes, items, or designs that are not
included in the project \-- and specifier's notes such as these.  To
seek a variance from requirements in the specifications that are
applicable, contact the Engineering Standards Manual Architectural
[POC](http://engstandards.lanl.gov/POCs.shtml#arch). Please contact POC
with suggestions for improvement as well.\
\
When assembling a specification package, include applicable
specifications from all Divisions, especially Division 1, General
requirements.\
\
Specification developed for ML-4 projects.  For ML-1, 2, and 3
applications, additional requirements and independent reviews should be
added if increased confidence in procurement or execution is desired;

            require extra precautions or provisions to ensure
            satisfactory performance of the work.

            1.  Field verify all dimensions and other work conditions
                affecting the installation of carpet tile.

            2.  Unless otherwise noted or approved on drawings, begin
                laying tile at centerline.

            3.  Comply with carpet tile instructions for direction of
                carpet tile. Unless otherwise noted on drawings align
                pattern and pile in the same direction, parallel to the
                centerline of the area or room.

            4.  Extend carpet tile under open-bottom obstructions and
                under removable flanges and furnishings, and into
                alcoves and closets of each space. Existing systems
                furniture shall be raised or removed to accommodate
                continuous carpet installation.

            5.  Provide cut-out where required, and bind cut edges where
                not concealed by protective edge guards or overlapping
                flanges.

            6.  Install carpet edge guard where edge of carpet is
                exposed; anchor guards to substrate. Use full-length
                strips only.

            7.  Expansion Joints: Do not bridge building expansion
                joints with carpet tile; provide for movement.

            8.  Carpet tile shall be free from movement when subjected
                to traffic.

            9.  Do not use pieces smaller than 1/3 of a standard tile
                without prior approval by LANL.

            10. Provide mockup for approval by LANL of special
                cuts/effects such as mitered corners at borders or
                graphic patterns that are prepared and installed onsite.

            11. Where there are floor finish material changes at doors,
                place centerline of abutting materials below door.
