Happens all the time when bureaucrats and politics are involved. They likely wanted the E-B launched on a certain date for political reasons, so "rush it out of the door, it's not like it's going into anything complex" is in play.
My group had this in 2012 - a new lab building had been set up and there was pressure to move us in (from our shittier, smaller but working lab) in order to have occupancy so it looked good when the stakeholders visited. Never mind that we couldn't do any actual work in there due to lack of various facilities....
Oh, as lab leader I knew - and protested - but was told I'd be "playing football with my own head" if I didn't toe the line...
