The I23 Lab Group of the Progenitors is based in a large multi-purpose facility that consists of several buildings and levels and is located on the western end of the crescend layout of the construct site. On the surface, the large greenhouse-arboretum is clearly visible from afar. Within this group of half domes a number of micro-climates have been set up which serve both scientific and recreational purposes. Various forms of genetically engineered plants and animals live in this self contained ecology which even features seasonal cycles and changes in climate.
Overlooking the arboretum are the offices and quarters of the Research Director and the Primary Investigators of the Construct.
Around the arboretum - on the ground floor - the living quarters of the Investigators, the Research Assistants, the Students and the unenlightened personnel are laid out around lobbys with subdued lighting and recreational facilities like bioresonance chambers and physioergonomics training rooms are ready for everybody to use. Beneath the arboretum and greenhouse buildings two levels of classrooms, auditoriums and offices are built into the sloping hillside. The three levels of laboratories and research spaces that come next are all subterranean delvings into the rock. The fourth and last of the subterranean levels is a high security containment facility where clones, test subjects and even more extreme Damage Control creatures are stowed away. This level may only be accessed with the highest security clearance, not even the NWO is allowed here.
Currently the I23 Lab Group has facilities for the Gengineers and the FACADE Engineers. The Pharmacopeist Lab is still in existence but is only staffed by a skeleton crew of one Student and three unenlightened lab technicians after the Primary Investigator Tristao Cargnelli was uncovered as a Nephandi Infiltrator and the Research Assistant Guido Rinaldi got transferred to a Void Engineer ship. As mentioned above, Damage Control also has it's own covert facility in the construct's lowest level. Not even the RD knows what's going on there all the time.
