Installation of the exterior sheathing and air vapor barrier has continued on the East side of the new addition and is progressing towards the West. Additional slab-on-grade concrete placements have also occurred and are tracking to be completed in April. The lower level of the new addition has received crushed stone in preparation for pouring the concrete floor base. Installation of overhead mechanical, electrical, and plumbing equipment has also continued throughout all floors of the new addition. The underground utilities and floor of the existing building have been backfilled, and the floor insulation is now being installed on top of it.
