The program's capstone: a new mixed-use building design assignment, a case-study recall exercise across all 5 real projects, a Module 17 field-verification exercise, a grading rubric, and your certificate of completion.
This closing module is not a new topic — it is where everything from Modules 1 through 20 gets applied to one more building this program has not already solved for you: a 6-story mixed-use building combining ground-floor, customer-facing retail fixtures with five floors of private-use apartments on one shared water service and DWV system. A complete fixture-unit takeoff, pipe and riser sizing, a DWV stack decision checked fresh against this building's own branch-interval count, and a venting design anchor the assignment in the same shown-work discipline this program has used throughout.
Completing this module's quiz below marks the whole program complete and unlocks your certificate of completion from the program hub — a self-issued personal completion record and portfolio artifact, not a licensing credential.
