2021B - DM - Riverdale Ridge HS Doors and Expansion Joint Issue

School District 27J is seeking proposals from qualified firms to provide the necessary professional services for the associated design and possibly permitting and construction administration for redesign of an expansion joint/firewall/ door reconfiguration at Riverdale Ridge Hight School.  The school has a 2 hour seperaton wall on top of a foundation design trasnstion.  One side of the wall is SOG concete over conditioned soil and the other side is on an elevated slab over crawl space.  The side with the SOG has started to heave (as expected in the original soils report) and has led to issues with doors opening the entire length of this wall.
