Weekly Activities

December 21, 2015: Pre-drilling for obstructions along the sheet pile alignment sheet pile installation continued. As of December 18, 2015, Posillico has installed a total of 42 sheet piles. The elevations of the installed sheet piles will be surveyed to ensure proper installation. Flushing of the joints of the installed sheet piles with water has begun in preparation for grouting.

CAMP data is reviewed and compared to specific NYSDEC/NYSDOH approved criteria, known as “Action Limits.” As a result of this evaluation process, site conditions are categorized into two categories, “Operational Condition” and “Action Condition.” The “Operational Condition” is applicable when the data is below the “Alert, Response and Action Limits”, and means that normal operations can continue. The “Action Condition” occurs when one or more of the fifteen minute average measurements for Dust (PM10), Total Volatile Organic Compounds (TVOC) or Odor Intensity are greater than the background or upwind measurement by the specified “Action Limits.” Reaching an Action Level requires corrective action or stopping work until the condition is addressed or abates. During the period from Monday, December 14, 2015 through Friday, December 18, 2015, four portable CAMP stations were in-use and measured TVOC and PM10. Fifteen-minute averages for TVOC and PM10 data remained below the Action Limit.

For the week of December 21, 2015, Posillico will continue sheet pile installation and flushing the joints of the installed sheet piles.
