Examine areas and conditions under which supports and anchors are to be installed. Do not
proceed with work until unsatisfactory conditions have been corrected in manner acceptable to
Installer.
PREPARATION:
A.
Proceed with installation of hangers, supports and anchors only after required building structural
work has been completed in areas where the work is to be installed. Correct inadequacies
including (but not limited to) proper placement of inserts, anchors and other building structural
attachments.
B.
Prior to installation of hangers, supports, anchors and associated work, Installer shall meet at
project site with Contractor, installer of each component of associated work, inspection and
testing agency representatives (if any), installers of other work requiring coordination with work of
this section and Architect/Engineer for purpose of reviewing material selections and procedures
to be followed in performing the work in compliance with requirements specified.
INSTALLATION OF BUILDING ATTACHMENTS:
A.
Install building attachments at required locations within concrete or on structural steel for proper
piping support. Space attachments within maximum piping span length indicated in MSS SP-69.
Install additional building attachments where support is required for additional concentrated loads,
including valves, flanges, guides, strainers, expansion joints, and at changes in direction of
piping. Install concrete inserts before concrete is placed; fasten insert securely to forms. Where
concrete with compressive strength less than 2500 psi is indicated, install reinforcing bars
through openings at top of inserts.
B.
Use power driven anchors or expansion anchors at concrete structure.
C.
Install supplementary steel angles, fastened or welded to building structure as required to support
pipe and accessories. Use 3" x 5" x 1/4" steel angle with long leg vertical, or heavier if required.
INSTALLATION OF HANGERS AND SUPPORTS:
A.
General: Install hangers, supports, clamps and attachments to support piping properly from
building structure; comply with MSS SP-69. Arrange for grouping of parallel runs of horizontal
piping to be supported together on trapeze type hangers where possible. Install supports with
maximum spacings complying with MSS SP-69. Where piping of various sizes is to be supported
together by trapeze hangers, space hangers for smallest pipe size or install intermediate supports
for smaller diameter pipe. Do not use wire or perforated metal to support piping, and do not
support piping from other piping.
B.
Space hangers 5'-0" on center for steel, iron, and copper pipe up to and including 1 1/2" nominal
size.
C.
Space hangers 10'-0" on center for steel, iron, and copper pipe above 1 1/2", or as otherwise
shown on the drawings. Piping size 12" and above shall have hanger spacing at 12'-0"
maximum, unless shown otherwise on the drawings.
D.

from movement will not be transmitted to connected equipment.
L.
Pipe Slopes: Install hangers and supports to provide indicated pipe slopes, and so that maximum
pipe deflections allowed by ANSI B31 are not exceeded.

through completion of the inspection. Inspect all joints for leaks.
Finished Plumbing Test Procedure: After the plumbing fixtures have been set and their
traps filled with water, their connections shall be tested and proved gas and water-tight.
Plug the stack openings on the roof and building drain where it leaves the building, and
introduce air into the system equal to a pressure of 1" water column. Use a "U" tube or
manometer inserted in the trap of a water closet to measure this pressure. Air pressure
shall remain constant without the introduction of additional air throughout the period of
inspection. Inspect all plumbing fixture connections for gas and water leaks.
