There would be no way that an ark project can be built alongside the crucible since the galaxy is basically pouring all its resources into it (see the specter terminal and codex). There wouldn't be enough man power and resources to build one.
Hackett's speech was hyperbole. If *all* resources were being poured into the crucible, then there would never be replacement ships or repairs done to any damaged ship or vehicle since everyone who could do any engineering would be at the crucible (including the normandy's engineers).

Eh that was the basis of the ME2 storyline
N7 still exist during its launch that would mean the STG and ceberus could just as easily still be around.
One N7 agent = N7s are still around? As i already mentioned, at best a handful of agents would get in and its likely they would have to have other skills other than "pull trigger", "lob grenade", "aim overload/incinerate/warp/etc".
But lets go with the entire ark being filled with STG, spectres, N7s and cerberus as a joke
The cryo pods fail! What do they do?
STG agents suggests giving a speech about how the pod dwellers will be remembered
The N7s suggesting snap freezing everyone every few seconds or shield bashing with freezing shields.
The spectres want to shoot people up with cryo ammo because they have a ton of level 4 cryo
Cerberus want to go with using the cryo blast because they saw people spamming it like no tomorrow
The one actual engineer on the ship suggesting fixing the pods.
STG agents say they are not reseach division
N7s say that its up to HQ to provide them replacement armor and swords so they never actually fix stuff
Spectres say that they are willing to get the council to pay for engineers to fix the pod
Ceberus agents says that the illusive man knows already and the pods will be fixed automatically
All of that tech existed before the reaper's even showed up, having neew tech would be just as important as well since it could mean the difference between life an death. It has the potential to be a game changer.
Eh? Some of that tech was fresh out of the oven, including the hover tank which you had to actually complete a small mission to recover. As i said new tech is nice but no one cares if cerberus gets new tech because when the ship launches, 99.99% (or more) of cerberus will be dead. Any cerberus agents that could get into the ark would have to be on the basis of their non combat skills because there is simply NO ROOM for an army of centurions, nemesis and atlas drivers.
Once in the ark and launched, any cerberus agents would not be in a position to ignore basic survival issues and instead go around murdering non humans unless they were all insane and want to kill off the human race as well (which btw is one of the species in the ark). That handful of cerberus agents would then have to survive
i) the travel to andromeda
ii) any planetary or stellar dangers at the landing site
They should be concerned since you don't want someone one compromising the survival of the others. It only takes one person to undo the hard work of many people.
Unless that person can
i) sabotage the entire ship in one go
ii) can avoid detection
iii) has a deathwish and doesn't mind dying
then there is no real reason to be concerned, not when there are plenty of other concerns (life support failing, collisions with signifacant masses, short circuits, failure of air/water generation or recycling systems, etc). Any person who tries to forment unrest while survival issues are omnipresent can expect to be shunned at first and later (if the action continues) thrown out the airlock by unanimous vote
