So this article references 24 months for construction. Does that mean 24 months before any launches or will the key structures go up first to get the site in business?
I work for a construction company and have built a pad and other much larger but less cool projects. So I can see several ways they can start using some aspects of the facility, horizontal building and erector while out buildings and some capabilities finish commissioning and check out. But by first launch I'd expect it to be 95% complete or more.
It will be intersting to see if they build in FH capability from the start in the RP1 & LOx systems or add capacity later. That's one way to save some time and money.
I think the mayor is optimistic with 18-19 months. SpaceX moves quick but this is a green field and they don't have the advantage of plopping down on top of an existing civil structure for the pad and trench. That is going to be a massive amount of concrete. And you can't prefab that and bring it to site. Also site civil for communications, data and those accessory things that have to go in.
Then what company do you use and what is there culture in building. After award project quality and schedule are not entirely up to the end user (SpaceX). If you make a bad pick wih a contractor it's a long hard battle to completion.
SpaceX can do some things themselves but not everything and this is significantly more than they've done previously.
Look at Orbitals experience in Virginia and how facility completion held that up.
Pick wisely SpaceX, pick wisely.
PS: I'd love to build another pad, call me!!!
