Roosevelt Island Cornell NYC Tech Campus Construction Update - Interior Demolition/Abatement Of Goldwater Hospital Continues, New Barging Operator Removing Waste/Delivering Empty Containers, Weather Conditions/Wind Patterns To Be Analyzed And Air Quality Monitoring Results

Here's the most recent Cornell NYC Tech Construction Update describing the demolition of Goldwater Hospital.

According to Cornell NYC Tech Construction Update:
June 6 - June 20 Look Ahead

Interior demolition and interior abatement are progressing well across the site. Interior demolition is complete in all but two buildings (Building B and E). The interior abatement crews are currently spread across four buildings. They have completed the abatement work on the Building C roof. The regulatory agencies that are involved in the project have requested that the contractor perform some additional work at this time in advance of structural demolition. As a result, small crews have remobilized and returned to Phase 1 (Building D and F).

The weather station has been removed from the roof of Building J. Consultants will soon begin to analyze the data to develop a comprehensive understanding of weather conditions and wind patterns at the site.

The transition to the new barging operator has been seamless. They have successfully made multiple trips to Roosevelt Island to remove waste and deliver empty containers. The next barge trip will likely take place late in the week of June 9th.
I asked Cornell NYC Tech Assistant Director of Government and Community Relations Jane Swanson:
Can you provide more specific reasons for the additional abatement work required by regulatory agencies that is referenced in Cornell Construction update....
Ms. Swanson replied:
There is a layer of asbestos-containing mastic on the inside face of the exterior masonry walls. We removed it safely in Building C, but left it intact in Buildings D and F, as we were considering an abatement methodology that included removing it as part of the exterior wall structural demolition. At this time, however, we have proposed an abatement methodology that requires removal of the mastic prior to structural demolition, so we intend to re-enter Buildings D and F to complete the removal of this interior mastic.
Also, the most recent air quality monitoring data from Cornell NYC Tech at the Goldwater Hospital site.

Air Quality Action Levels
Background corrected particulate concentration data from the site is compared to particulate action levels. This correction is calculated by subtracting the upwind concentration from the downwind concentration and provides the concentration of particulates being generated by site activities. The specific action levels and their response are as follows

Inclement Weather
Monitoring is not conducted during rain events as precipitation acts as a natural suppressant and prevents the migration of particulates. In addition, moisture can impact the accuracy of the data from the monitors.

It would be interesting to know what's "normal", we are only seeing average and max, but compared to other areas on the island, how are those numbers comparing. It's hard to judge if there's no comparison no?
