Okabe and Daru started building the time machine before 2025. That is why it bears Okabe's nickname for Kurisu, and...

Spoiler (highlight to read) [ in one of the world lines in the Epigraph Trilogy due to certain circumstances, they even build C193 by 2025. ]

However, according to the official guidebooks, Okabe consistantly dies in 2025 and the time machine whether C203 or C204 is used by Suzuha in 2036 in 1.130212%, 1.130205%, 1.130426→1.130238%, and 1.129848% Edit: The Q&A section A30 of the first official guidebook, states that Daru is the one who completes building the time machine, so that means that he can finish it after Okabe has already passed, just like he did in the Alpha AF.

As for why Suzuha knew about the video D-Mail from 2025 Okabe, she had known him before his death in the Beta AF, but even more importantly she had been told the whole plan. Thus she knew about the video D-Mail, the need to save Kurisu to stop WWIII, and that they needed to go -0.081609% further in order to reach a world line free of the Beta AF's convergence, the Steins Gate. Edit: All of that was what Okabe came up with before his death in 2025.
