To facilitate installation of the tower crane for the Science & Engineering Hall project, the 2200 block of H Street will be closed to vehicular traffic except for access to parking garage from 22nd Street only (no 23rd Street access to H Street). Staff will be on site to direct traffic accessing garage. Per approved DC permits, equipment arrival will begin as early as 4:00 a.m. and installation work will begin at 7:00 a.m. Work is expected to be completed by Sunday evening at which time the vehicular lanes and sidewalks will be re-opened.

August 3, 2012
After a long period of no daily controlled blasting activities at the Science & Engineering Hall site, this activity resumed August 2, 2012. Depending on site conditions, there is a possibility of additional blasts within the next several weeks. Tower crane footing will be installed next week with anticipated installation of the tower crane on August 11, 12. Upcoming work over the next two weeks includes removal of rock and installation of rock bolts for concrete.

July 23, 2012
Anticipated upcoming work over the next two weeks includes continued installation of vertical bars/toe ties throughout site and proceeding of excavation on south and east elevations to next lift of rock/clay. Controlled blasting is not likely to commence again until the southern end of the site is fully excavated and operations move northward again. The amount of blasting remaining is expected to be minimal.

July 9, 2012
Anticipated upcoming work over the next two weeks includes completion of fourth tier tiebacks as well as continued hauling of rock, soils, and rubble and the installation of rock bolts and shotcrete in the southern and eastern edges of the site. Additionally, rock excavation and shotcrete operations along the east side of Fulbright will occur.

Controlled blasting is not likely to commence again until the southern end of the site is fully excavated and operations move northward again. The amount of blasting remaining is expected to be minimal.

June 26, 2012
Work will not occur on Wednesday July 4 in observance of Independence Day. Anticipated upcoming work over the next two weeks includes completion of third tier tiebacks as well as continued hauling of rock, soils, and rubble in the southern and eastern edges of the site. The underground storage tank between Munson and JBKO is scheduled for removal in coming weeks.

Controlled blasting did not occur last week to facilitate continued removal of old ramp on the south end of the site. Blasting operations will likely be sporadic (once or twice a week) between now and mid August as mass excavation continues.

June 18, 2012
Controlled blasting did not occur last week to facilitate continued removal of old ramp on the south end of the site. Hauling of rock, soils, and rubble continues in the southern and eastern edges of the site, as well as lagging and tie-back operations. With rock mass excavation and controlled blasting complete at the Building K area of the site, controlled blasting and rock excavation focus now shifts to the eastern side of the site and the area under the old ramp (southern half of site). Blasting operations will likely be sporadic (once or twice a week) between now and mid-August as mass excavation continues. 

June 4, 2012
Controlled blasting did not occur last week to facilitate continued work to complete the new entrance ramp on the north side of the site (allowing trucks to exit site at the north end near Eye Street instead of the south end near H Street). Rock excavation and earthwork focus continues at Building K footprint. Additionally, excavation and perimeter shoring efforts at the old ramp location continues.

May 2, 2012
While it was initially anticipated when blasting began in late April that this activity would take place on most weekdays (depending on weather and soil conditions) between 10:30-11:00 a.m., site logistics necessitate increased flexibility as to the timing of when each day’s blast will occur. As such, controlled blasting activities will now occur at either approximately 11:00 a.m. or Noon weekdays (again, depending on weather and soil conditions) on the days that blasting is required. This change will be in effect through the duration of blasting activities which are anticipated to continue through late June or early July.

Controlled blasting did not occur for most of last week due to efforts to complete new entrance ramp on the north side of the site (allowing trucks to exit site at the north end near Eye Street instead of the south end near H Street). Rock excavation and earthwork focus continues at Building K footprint.

May 14, 2012
Controlled blasting continues in the middle of the site most days, weather permitting, and is progressing toward the Building K footprint. Adjustments continue to be made to original approximate 10:30 a.m.-11:00 a.m. timeframe window for blast times on weekdays. Recent foundation work includes continued installation of vertical bars and toe ties along 22nd Street and Fulbright North. Earthwork includes continued work at Building K footprint and Fulbright east, continued rock excavation at Building K footprint and Munson south, and continued development of new entrance ramp on the north side of site.

May 4, 2012
Controlled blasting continues in the middle of the site most days, weather permitting, and is progressing toward the Building K footprint. Original approximate window of 10:30 a.m.-11:00 a.m. may be increased by one hour so blasting may occur between 9:30 a.m.-11:00 a.m. Recent foundation work included installation of vertical bars and toe ties along 22nd Street and Fulbright North. Earthwork includes continued work at Building K footprint and Munson south and development of new entrance ramp on the north side of site.

April 27, 2012
The first controlled blasting in the middle of the site occurred on April 26 at apx. 10:50 a.m. Additional blasting will continue each weekday for 4-5 months between 10:30 a.m. to apx. 11:00 a.m. depending on weather and soil conditions. Recent foundation work included installation of vertical bars and toe ties an Munson Hall (which will continue at Fulbright north). Earthwork includes continued work on new entrance ramp on the north side of site and continued excavation/removal of rubble in the middle or project site and along 22nd Street.

April 2012
Excavation has progressed to the point that the contractor for this project will begin controlled blasting activities on the project as soon as April. These activities are highly monitored to ensure they are within regulated limits, do not adversely affect any adjacent structures, and have minimal impact on day-to-day routine of those living an working in close proximity to the site (the same as experienced in 2008 during the several months of controlled blasting at the Square 54 for The Avenue). When blasting begins, it will occur on most, but not all, weekdays typically between 10:30-11:00 a.m. For many, the most noticeable part of this activity will be the series of air horns that sound to notify the worksite and the public of the activity at 15 minutes, five minutes, and one minute prior to the blast, and immediately following the blast to indicate "all clear." The blasting activity itself will result in limited sound and vibration impacts that have been compared to that of a door slamming or a large truck passing and that last, at most, a few seconds (this will vary depending on a number of factors, including weather and site location). Since this activity agitates soil, occupants of buildings immediately adjacent the site are asked to keep windows closed during the blasting period (residents will not need to evacuate building during this). Buildings adjacent to the site will be closed temporarily in the few minutes before and during each blasting event and adjacent streets will be temporarily closed for a few minutes during the blasting events (at the direction of D.C. Metropolitan Police and with exceptions for emergency vehicles). Blasting materials will not be stored on site.

April 13, 2012
While excavation efforts have yet to discover rock that requires controlled blasting for removal, it appears this may occur within the next several weeks. This sort of timing fluctuation is typical when working with a large project site that has varying soil conditions and will not impact the project's scheduled completion in late 2014. Related to this, there will be a delivery this Saturday of the mats used to cover the ground in the construction site on and near the blasting activities.

Recent foundation work included completion of tieback drilling on the north side of Fulbright as well as continued installation of lagging on 22nd Street and south side of Munson Hall, and third tier cross lots. Earthwork includes continued work on new entrance ramp on the north side of site and continued excavation/removal of rubble in the middle or project site and along 22nd Street.

April 6, 2012
