You've done the engineering, and the customer signed it. Now it becomes steel on a floor, and the design leaves your hands. This final part walks the whole delivery arc: the handoff that gets every trade on the same page before anyone mobilizes, the execution support that keeps the field moving and the as-built honest, the commissioning and acceptance that proves the system on a sustained run under real load and designs the service model that keeps it running, and becoming the engineer, your first 90 days and the habits that carry you into the Capstone. Deliver it well and the work survives long after the install crew drives away.
Prove it, accept it, keep it running. The delivery arc of Part VIII.
