1.3.2
Qualifications
1.3.2.1
Manufacturer
Metal building shall be the product of a recognized steel building systems
manufacturer who has been in the practice of manufacturing steel buildings
for a period of not less than 5 years. The manufacturer shall be chiefly
engaged in the practice of designing and fabricating metal building systems.
1.3.2.2
Installer
Erector shall have specialized experience in the erection of steel building
systems for a period of at least 3 years. The erector shall furnish
temporary guys and bracing where needed for squaring, plumbing, and
securing the structural framing against loads acting on the exposed
framing, such as wind loads and seismic forces, as well as loads due to
erection equipment and erection operation. Structural members shall not be
field cut or altered. Welds, abrasions, and surfaces not [shop primed]
[galvanized] shall be primed after erection.
1.4
DESIGN REQUIREMENTS
**************************************************************************
NOTE: Metal buildings should be specified using
MBMA criteria except that loads and load
which refers to ASCE 7 for wind, live and snow loads
and TI 809-04 for earthquake loads.
Designer has the option to delete or replace the
referenced TI's with applicable criteria, here and
in other paragraphs.
**************************************************************************
Criteria and definitions for metal building systems shall be in accordance
with MBMA MBSM, except criteria for seismic loads shall be in accordance
with TI 809-04 and other loads and load combinations in accordance with
ASCE 7.
1.4.1
Foundations
**************************************************************************
NOTE: The following paragraph is intended to be a
synopsis of the foundation report, and will be
supplemented with additional data as required. When
dealing with soil, a larger factor of safety is
used. Unlike steel and concrete, which are
manufactured, controlled, and tested to meet
prescribed standards, soils are natural materials.
Therefore it is common practice to apply a factor of
safety of at least 3.0 in soil engineering work.
**************************************************************************
Foundations shall be designed for an allowable soil bearing pressure of
[_____] Pa, psf, a minimum bottom of footing depth of [_____] mm feet below
finish floor elevation, a factor of safety of 1.5 for overturning, sliding
and uplift, and a concrete compressive strength as specified in Section [
03300A CAST-IN-PLACE STRUCTURAL CONCRETE][03300N CAST-IN-PLACE CONCRETE].
