Yeah I'm curious too - though you don't really need a very clean room at all for engine assembly (I worked in semiconductor manufacturing, talk about needing cleanroom *****)
1 mil is 25 microns, and that's on the order of engine block tolerances. Even precision machining goes down to half a mil, 12.5 microns. Class xx/xxx/xxxx/xxxxx cleanroom specs usually deal with <10 micron particles
I doubt the environmental conditions need any modifications - yeah you care about the effects of humidity/pressure/temperature but if you work out the math for all with the dissimilar materials involved, from an engineering perspective the difference is below tolerance thresholds

. The main goal for us was to keep the engine assembly away from the general work and fabrication area to keep any metal particles away from the bearing surfaces. Keeping the temperature consistent is also important for proper clearance measurements. For these reasons we devoted a room for assembly that is far away from the fab area and has two well sealed doors separating it from the main shop. This room is technically part of the back office, so it shares the HVAC with that office as well.

Thanks for the patience!
Now back to my engine assembly dungeon!
