| (a) "Supporting evidence" includes:
(1) product evaluations;
(2) installation instructions from the manufacturer
for the product;
(3) test data;
(4) written evidence from inspections--for example,
an inspection report;
(5) photographs;
(6) video recording;
(7) plans, either as-built plans (plans that demonstrate
compliance with the applicable building code for the design of the
structure), design drawings, shop drawings, or sketches; or
(8) any other documentation or other form of evidence
that supports statements made in the application, design, or postconstruction
evaluation report submitted to TDI, as applicable.
(b) To verify that an engineer's postconstruction evaluation
report confirms the completed improvement's compliance with the applicable
building code under the plan of operation, as required under §5.4604
of this title (relating to Certification Form for Completed Improvement),
it must include supporting evidence. TDI may also request supporting
evidence, as applicable, to verify an engineer's application, sealed
design, or affirmation under §5.4604(a) of this title. The supporting
evidence may include the following, as related to the part of the
structure being certified.
(1) Roof covering certifications.
(A) Supporting evidence identifying all products and
components included in the scope of the certification, including roof
covering, fasteners, underlayment, roof deck, roof vents, skylights,
and all other parts of the roof-covering assembly.
(B) Manufacturer's installation instructions, product
evaluation reports, or test laboratory reports, and code-required
installation requirements for all components included in the scope
of certification (for example, see subparagraph (A) of this paragraph).
(C) Supporting evidence that the components of the
installed building products meet or exceed the code-required design
pressures.
(D) Supporting evidence verifying that the roof covering,
roof vents, and skylights are installed according to the manufacturer
installation instructions, product test reports, and specifications
in the applicable windstorm building code.
(E) Applicable information listed in §5.4626 of
this title (relating to Substantiating Information).
(2) Building product certifications.
(A) Supporting evidence identifying all products included
in the scope of the certification, including windows, side-hinged
doors, sliding doors, overhead doors (sectional or rolling), exterior
wall coverings, and other applicable building products.
(B) Manufacturer's installation instructions; product
evaluation, reports, or test laboratory reports; product certifications;
and code-required installation requirements for the building products
included in the scope of the certification.
(C) Supporting evidence verifying that design-pressure
ratings for all building products meet or exceed the required design
pressures as specified in the applicable windstorm building code for
the installation.
(D) Supporting evidence verifying that the building
products that are required by the applicable windstorm building code
were certified by a certification agency, such as the Window &
Door Manufacturers Association or the American Architectural Manufacturers
Association; are properly labeled; and have valid certifications.
(E) Supporting evidence recording all information on
certification labels and verifying that the product test pressure
exceeds code-required design pressure, and that building products
are within the maximum size tested on each label and are installed
exactly as tested.
(F) Supporting evidence specifying the minimum design
pressures required by the applicable windstorm building code.
(G) Applicable information listed in §5.4626 of
this title.
(H) Where the applicable windstorm building code requires
windborne debris protection, supporting evidence either verifying
the product is impact-resistant or protected with a windborne debris
protection system. Where the applicable code requires windborne debris
protection, the protection must be installed according to manufacturers'
instructions and product test reports.
(3) Entire new building, existing building, or a new
addition to an existing structure.
(A) Supporting evidence verifying complete load path
as specified by the applicable windstorm building code, including
connections between roof, walls, floor, and foundation.
(B) Supporting evidence verifying roof coverings as
specified under paragraph (1) of this subsection.
(C) Supporting evidence verifying building products
as specified under paragraph (2) of this subsection.
(D) Building plans, such as structural drawings from
the engineer of record or as-built plans that demonstrate compliance
with the applicable windstorm building code. The plans must show items
such as lateral resisting elements, wall framing, roof framing, floor
framing, and other pertinent elements of the structure that are included
in the scope of work for the certification.
(E) Supporting evidence verifying the foundation system,
such as existing plans or as-built plans. The plans must show the
location of anchors, ties, or straps; pile locations; or other pertinent
elements of the structural system that are included in the scope of
work for the certification.
(F) For additions, supporting evidence verifying whether
the addition is attached or detached from main structure. If the addition
is attached, the supporting evidence must specify the load on the
existing structure, the load imposed by the addition on the existing
structure, and if the existing structure and the connection will satisfy
the combined loading. Attached additions rely on the existing structure
for stability and strength. Detached additions are independent of
the existing structure. Supporting evidence must also verify load
path from addition to existing structure, if applicable.
(G) Applicable information listed in §5.4626 of
this title.
(c) Failure to provide the documents requested by TDI
could result in a denial of a Certificate of Compliance for Completed
Improvement (Engineered), Form WPI-8E, or other action taken by TDI
as stated in §5.4640 of this title (relating to Oversight) or §5.4642
of this title (relating to Disciplinary Action).
(d) For each component inspected, including roof, window,
door, garage door, or exterior cladding, the engineer listed on the
certificate of compliance for completed improvement must retain the
supporting evidence and applicable information described in this section
for that component for five years from the date of the most recent
certification application submitted on the structure.
(e) All supporting evidence must be submitted to TDI
electronically using either the Windstorm system or by email to windstorm@tdi.texas.gov.
The Windstorm system can be accessed on TDI's website.
