Site 102B/November 1, 2012: Preparations in advance of Hurricane Sandy ensured no damage to project site during the storm.  The sidewalk and curb lane on the east side of 21st Street adjacent the project site (approximately south of Corcoran Hall to Woodhull House) was closed October 26 and will remain for the duration of the project. A groundbreaking ceremony was held October 18, 2012, click here for details. Cameras are anticipated to be installed in coming weeks which will offer online viewing of time lapsed project progress pictures.

Final sediment and erosion control measures were installed at the site and excavation is anticipated to begin in coming weeks.  Work continues on the demolition of the Corcoran Hall exterior stairwell and is anticipated to continue for several additional weeks – this work has been coordinated with professors and Deans to mitigate the impact, to the extent possible, of this work on classroom activities. Work is near completion on the Bell Hall emergency power relocation and air handler unit replacement.  Selective demolition continues at Woodhull House.

Site 102B/October 8, 2012: Work has proceeded to the point the sidewalk and curb lane on the east side of 21st Street adjacent the project site (approximately south of Corcoran Hall to Woodhull House) is scheduled for closure as early as this week and to last for the duration of the project. Work is scheduled to begin this week on the demolition of the Corcoran Hall exterior stairwell and is anticipated to continue for several weeks – this work has been coordinated with professors and Deans to mitigate the impact, to the extent possible, of this work on classroom activities. Work has finished on installation of the new electrical duct bank from Bell Hall across University Yard to vicinity of 20th & H Streets – resodding will occur later in October/November.  Work continues on Bell Hall emergency power relocation and air handler unit replacement as does selective demolition at Woodhull House and installation of wooden perimeter site fence facing University Yard.

Site 102B/September 21, 2012: Work in coming weeks continues to focus on site preparation, including: installation of additional perimeter fencing; re-routing of PEPCO electrical lines connecting site to power hub at 20th & H Streets (including excavating trench diagonally through University Yard); installation of project scaffolding and temporary air handling units; relocation of existing materials and services in Corcoran Hall; rerouting of some utilities in Bell Hall.  Also, demolition of the exterior stairwell on the south side of Corcoran Hall is anticipated to begin next week.  Given this work will create periods of above average noise, these activities are being coordinated with Deans and Professors in adjacent academic buildings. Selected demolition will begin in Woodhull House.

Site102B/September 10, 2012: Work begins Thursday September 20 and will last approximately two weeks (pending weather and site conditions) to install a new below-grade electrical conduit between the GW Museum site and H Street power hub. This work will be temporarily ceased during Alumni Weekend so as to not impact events taking place on University Yard during this weekend.  Work will include an approximate 10 foot wide path for the excavation, equipment, and workers. Work will begin near Bell Hall and proceed diagonally across University Yard northeast toward H Street (near 20th & H Streets) in three phases each focusing on approximately a third of University Yard. The project team has coordinated with University Events to minimize disruptions to events scheduled on University Yard during this time period. Once the work is completed and the trench is backfilled, a new layer of sod will be placed on the ground and alumni bricks will be returned in the same order as they are currently placed.
