field in the fabric as well as removing any wrinkles. This process should be in the
responsible charge of the most knowledgeable fabric person on the jobsite. In the case
of very large or complex structures, the structural engineer should assist in
determining how or when the proper level of tensioning is achieved.
Non-destructive pre-stress measurement devices exist that can be placed onto the
fabric as a local temporary ring support to measure the pre-stress. Otherwise,
lengthening the cables or the fabric stretch itself may be indicators that the desired
pre-stress has been achieved.
After installation, architectural/structural fabrics have shown themselves to be quite
durable and essentially trouble-free. On rare occasions, structures may require minor
re-tensioning due to creep of pre-tensioned fabrics. In practice, this is almost never
required.
9.3.5 Other
All sharp edges which have the potential to rub or touch the fabric in any way that
could result in fabric damage shall be rounded, padded, etc. so as to preclude this
possibility.
The fabricator and the installer shall each have, in place, a quality assurance program
which addresses the particular issues related to the building of a fabric structure.
The fabricator and the installer shall collaborate to provide an emergency repair kit to
the structure's owner. This repair kit shall contain not only the necessary supplies and
special tools to perform the repairs, but also the necessary instructions on how and
when to make repairs. This kit shall contain instructions on who to contact in case
problems of a more serious nature should arise. This kit should advise the user of any
safety issues related to the act of performing repair work on a fabric structure.
