inspection of on-site construction is complete. A copy of the other
on-site inspection reports shall be given to the owner if requested.
(g) Destructive disassembly shall not be performed
at the site in order to conduct tests or inspections on the modules
or modular components completed in the plant and certified by the
decal or insignia attached by the manufacturer, nor shall there be
imposed standards or test criteria different from those required by
the approved installation instructions, on-site construction documentation,
and the applicable mandatory building code. Nondestructive disassembly
may be performed only to the extent of opening access panels and cover
plates.
(h) Foundation system designs. A licensed professional
engineer (or architect for one and two family dwellings or buildings
having one story and total floor area of 5,000 square feet or less)
shall design and seal the foundation systems for each industrialized
house or building. Review by a DRA is not needed or required. A municipality
that regulates the on-site construction or installation of industrialized
housing or buildings may review the foundation system design for compliance
with the mandatory building code. Foundation system designs shall
comply with the mandatory building code referenced in §70.100
and §70.101 and shall contain complete details for the construction
and attachment of the house or building on the foundation, including,
but not limited to the following:
(1) address or area for which the foundation is suitable;
(2) minimum load specifications, including wind loads,
seismic design loads, soil bearing capacity, and if the foundation
is designed for expansive soils;
(3) site preparation details;
(4) material specifications;
(5) requirements for corrosion resistance, protection
against decay, and termite resistance;
(6) size, configuration, and depth below grade of all
footings, piers, and slabs including, but not limited to, details
of concrete reinforcement, spacing of footings and piers, capping
of piers, and mortar or concrete fill requirements for piers;
(7) fastening requirements, including, but not limited
to, size, spacing, and corrosion resistance;
(8) requirements for surface drainage; and
(9) details for enclosure of the crawl space, including
details for ventilation and access.
(i) Ground anchors. The use of ground anchors in the
installation of industrialized housing is not permitted. The use of
ground anchors in the installation of industrialized buildings is
allowed if deemed appropriate by a municipality or other political
subdivision. The foundation design shall be prepared by a licensed
professional engineer and shall contain complete details for the construction
and attachment of the building on the foundation, including, but not
limited to the following:
(1) address or area for which the foundation is suitable,
including a soil investigative report prepared by a qualified engineer
or a description of the soil type for which the anchoring system is
suitable;
(2) minimum load specifications, including wind loads,
seismic design loads, soil bearing capacity, and if the foundation
is designed for expansive soils;
(3) site preparation details;
(4) material specifications;
(5) requirements for corrosion resistance, protection
against decay, and termite resistance;
(6) size, configuration, and depth below grade of all
footings and piers including spacing of footings and piers;
(7) specification and installation requirements for
the tie-down anchoring system, including specifications for corrosion
resistance for the ground anchors and associated tie-down system;
(8) requirements for surface drainage; and
(9) details for enclosure of the crawl space, including
details for ventilation and access.
(j) Unique on-site construction details. Unique on-site
construction details as defined by §70.10(a) shall be designed
and sealed by a licensed Texas professional engineer (or architect
for one and two family dwellings or buildings having one story and
total floor area of 5,000 square feet or less) and review by a DRA
is not needed or required. The unique on-site construction details
shall comply with the mandatory building codes referenced in §70.100
and §70.101. A municipality that regulates the on-site construction
or installation of industrialized housing or buildings may require
and review the unique on-site details for compliance with the mandatory
building code.
