Work in coming weeks on the Central Utility Plant portion of this project includes completing excavation on the access shaft near the corner of H & 24th Streets (adjacent to Ross Hall’s entry ramp to the loading dock) and removing the existing foundation wall which is anticipated to be finished slightly ahead of schedule by early to mid-October. Since this work will create increased periods of noise, it will primarily occur outside of peak classroom use periods (early mornings and weekends) and within DC permitted hours for construction. Work continues on installation of the hoist used to convey materials/staff to work on upper floors and roof. Demolition/site preparation on the eastern portion of Ross Hall will soon be underway to prepare for new rooftop mechanical units associated with this project.

Exterior work is scheduled to begin in late September adjacent Ross Hall on the Eye Street Plaza to construct the exterior stairwell associated with this project.

Work in early September on the Central Utility Plant portion of this project, initial excavation work is underway on the access shaft near the corner of H & 24th Streets (adjacent to Ross Hall’s entry ramp to the loading dock) and is anticipated for completion in mid to late September. Following excavation will be the removal of the existing foundation wall which is anticipated to last approximately four weeks and will create periods of increased noise. Work continues on installation of the hoist used to convey materials/staff to work on upper floors and roof.
