Christian Horner has revealed the Red Bull Powertrains division is ready to go live "imminently".
Red Bull expects personnel to move into the new powertrains building "within the next eight weeks" as the team works through phase one of its three-phase plan.
"Within the next eight weeks the first members of the team will be moving in and Red Bull Powertrains comes live on campus," said Horner in a video update.
"Obviously, we've got more than 200 people recruited at the moment within the project and they're scattered around the site but they'll be moving into their new home imminently.
"This is just phase one of a three-phase plan for powertrains so we've still got further development with the manufacturing side which again will be based here in Milton Keynes.
"And the synergies that allows between chassis and engine and having the incorporation of that all under one roof, other than Ferrari, we're the only team in Formula 1 to have that."
Once vital equipment, such as the dyno, has been installed, Horner is confident it won't be long before power units designed by the team will begin to "come on stream".
"We're assembling a really talented technical team and operational team. We're welcoming the members that will be joining us from Honda HRD UK and its exciting times.," he added.
"I think it's a really exciting phase for Red Bull's journey in Formula 1 and you can see the commitment that is going in with what will be a world-class facility.
"The dyno is about to go through the commissioning stage now. It's been being installed since November last year. It's going to be exciting to see our first engines running and then it won't be long after that the first Red Bull designed power units start to come on stream.
"To have it all on-site, on-campus here in Milton Keynes is so exciting."
