WPI-8E Inspection Support for Completed Coastal Construction
WPI-8E certification-process support for completed construction in designated Texas coastal catastrophe areas. A Texas licensed professional engineer evaluates the structure and prepares sealed documentation for TDI review.
WPI-8 vs WPI-8E
ALFA Engineering, LLC is a Texas-licensed professional engineering firm providing windstorm engineering, TDI inspection services, and WPI-8E certification-process support for qualifying residential and commercial projects in designated Texas coastal areas. For completed construction, a Texas licensed professional engineer evaluates the structure and prepares sealed documentation for TDI review.
WPI-8 — Ongoing Construction
Inspected during construction while structural components are visible. Includes new construction, additions, re-roofing, and exterior envelope work. See our WPI-8 page.
WPI-8E — Completed Construction
Evaluated after construction is complete. A Texas licensed professional engineer assesses the structure based on available evidence and prepares sealed documentation for TDI review. More complex because concealed work must be evaluated indirectly.
A WPI-8E certificate of compliance may be needed when construction in a designated catastrophe area was completed without a WPI-8 inspection during the work. This includes structures built without windstorm inspections, re-roofing projects completed without inspection, and additions or alterations completed without documentation.
The WPI-8E process may require a signed WPI-2E application and sealed supporting documentation from a Texas licensed professional engineer. TDI issues the certificate of compliance — ALFA Engineering provides eligible engineering evaluation and documentation support. Eligibility and certification are subject to TDI review and applicable requirements.
Important: Concealed Work Limitations
Completed construction with concealed structural connections, framing, fastening, or roof assemblies may require removal of finishes for verification. Some concealed work may not be verifiable and may not qualify for certification. A thorough evaluation of available documentation and visible conditions is required before proceeding.
Supporting Evidence for WPI-8E
The WPI-8E process requires documentation to support the evaluation of completed construction. The specific requirements depend on the project type, construction details, and applicable TDI requirements.
Sealed Engineering Report
A Texas-licensed professional engineer's sealed report documenting the structural condition and windstorm compliance of the completed construction based on available evidence.
Construction Documentation
Permits, plans, photographs, inspection reports, and other documentation from the original construction that may support the evaluation.
Product Information
Manufacturer documentation, product evaluation reports, and installation information for structural components and exterior envelope elements.
WPI-2E Application
A completed WPI-2E application for completed construction, which may be required by TDI alongside the supporting engineering documentation.
Important Limitations to Understand
- Concealed structural connections, framing, fastening, and roof assemblies that cannot be visually verified may require removal of finishes or may not be verifiable.
- Completed construction that lacks sufficient documentation of the structural system may not qualify for certification.
- TDI reviews the submitted documentation and determines whether a certificate of compliance can be issued. Approval is not guaranteed.
- Some structures may require additional evaluation, testing, or remediation before certification can be considered.
- The WPI-8E process is generally more complex and time-consuming than the WPI-8 process for ongoing construction.
ALFA Engineering does not guarantee WPI-8E certification, does not promise approval, and does not represent that every completed project can be certified. The Texas Department of Insurance determines whether a certificate of compliance can be issued based on the submitted documentation and applicable requirements.
Information Needed for WPI-8E Review
WPI-8E Certification Questions
What is WPI-8E?
WPI-8E is a certificate of compliance for completed construction in designated Texas coastal catastrophe areas. It applies to structures that were not inspected during construction under the WPI-8 process. The WPI-8E process requires a Texas licensed professional engineer to evaluate the completed structure and submit documentation to TDI.
What is the difference between WPI-8 and WPI-8E?
WPI-8 applies to qualifying new or ongoing construction that is inspected during the work, while structural components remain visible. WPI-8E applies to completed construction that was not inspected during the work. The WPI-8E process is generally more complex because completed work must be evaluated based on available evidence rather than direct inspection of concealed components.
What is a WPI-2E application?
A WPI-2E is an application form for completed construction certification that may be required by TDI alongside the supporting engineering documentation. The engineer's sealed report and supporting documentation are submitted with the WPI-2E application for TDI review.
Can any completed building receive WPI-8E certification?
No. Eligibility depends on the project conditions, available documentation, and applicable TDI requirements. Concealed construction that cannot be verified, structures lacking sufficient documentation, or buildings that do not meet applicable windstorm construction standards may not qualify. TDI determines whether a certificate can be issued.
Does ALFA Engineering issue the WPI-8E certificate?
No. TDI issues the certificate of compliance. ALFA Engineering provides eligible engineering evaluation and documentation support services. A Texas licensed professional engineer evaluates the completed structure and prepares sealed documentation for TDI review. Eligibility and certification are subject to TDI review and applicable requirements.
What if my roof was replaced without a WPI-8 inspection?
A completed re-roofing project in a designated catastrophe area may be eligible for WPI-8E evaluation. The engineer would need to assess the completed roof system based on available evidence, which may include photographs, product information, and documentation from the roofing project. Concealed components that cannot be verified may limit the evaluation.
How long does the WPI-8E process take?
The timeline depends on the project complexity, availability of documentation, and TDI review. ALFA Engineering does not state a specific turnaround time. Contact us with your project information for a review of your specific situation.
