Inspection authority and certificate limits

ALFA Engineering, LLC is a Texas-licensed professional engineering firm providing windstorm engineering, project review, and certification-process support for qualifying residential and commercial projects in designated coastal areas. Availability depends on the property address, construction stage, and agreed scope.

For ongoing WPI-8 construction, ALFA can review the scope, help identify the applicable inspection path, and coordinate engineering documentation. An official construction-stage inspection must be performed by a TDI windstorm inspector or a Texas professional engineer holding the required current TDI appointment. ALFA does not claim an active TDI appointment; authorized inspection services are available only where the assigned engineer's required appointment is verified before scheduling.

Completed construction follows the separate WPI-8E evaluation and documentation process. Concealed work may not be verifiable. TDI reviews submissions and issues the certificates; ALFA does not issue certificates or guarantee eligibility, approval, insurance coverage, or review times.
