Partial Abstract: Precise elevation surveys indicate that established trends are continuing for settlement and tilt of the eight footings which support each elevated structure. Individual footings are settling and tilting at significantly different rates with the result that secondary stresses are accumulating in the structural frame. Cracked roof joists, buckled wall studs and failed wall plates provide evidence that the timber truss enclosure at each station is heavily overstressed and failing locally. Snow and ice have entered the DYE-2 truss enclosure through gaps in the distorted roof. Meltwater cavities created along the exterior wall of the DYE-2 truss enclosure have caused the wall-waler systems to separate. The truss enclosure at each station needs attention.
