Project Updates
Christos Tsiamis, EPA Remedial Project Manager, presented the updates.
Believe it or not, there is not much to tell you. I was here in February. A lot of work has been taking place these past months. Engineering. Logistics arrangements. It is more complicated from my perspective. Trying to think where we finished last time. A number of design documents – as we mentioned in the last meeting, the most important – next month, we’re going into action mode in the canal.
First, the construction of the cobbled wall in front of the Fulton MGP site from the top of the canal to Union Street on the east/Park Slope side. There will be a continuous sealed sheet pile wall that will prevent tar from entering the canal from the former Fulton MGP site. This work will be done by GGA, the engineers working with National Grid. This aspect is part of the Record of Decision (ROD) for the Fulton Manufactured Gas Plant site. Starting in June, you’ll notice barges. There will be lots of preparation on the land, the side near the existing bulkheads, surveys, and also construction of a noise barrier that will be placed to accommodate the needs of Eastern Effects [film production studio]. The next couple of months, we’ll have to remove any debris that will be there. There will be barges with equipment there.
Following that, approximately September to November, there will be equipment in the canal to auger. They will try to soften ground with the silent hydraulic press with no noise and no vibrations, and then along that length from top of canal to Union – this is a lesson learned from the pilot. When we brought in the hydraulic press, we learned it could go at some segments along Whole Foods, and then some that could not advance, so what we had to do was retrofit the press with an auger. It was very, very time consuming, so in discussion with contractors, we plan to do the augering first, and then do the construction. Come November, we will start the 55-foot-long sheet piles from the top of canal to Union Street. Sheet piles will be sealed, and that will be all that we do on that side. They have gotten enough pressure from me to keep to the schedule as much as possible. We will be finished with the Park Slope side by June 2020. The problem for me is at the same time as this wall, sheet piles will be placed at the other wall. This wall will be finished by December 2019. It is beyond my control, so now I’m faced with the situation where there will be many things in that small environment. We will still try to maintain the schedule. There are solutions, but it does present a management problem for us.
