JM Coull has begun cleanroom construction and façade improvements for ASML at their office building. JMC is working with H&R Design to build a 4,500 s/f EUV test cleanroom, an addition to the south side of ASML's facility, as well as replace the building's façade. The construction will take place over a 10 month period and will not disturb ASML's normal operations for the duration of the project.
