ww, That was quite an interesting article. Thanks. > Fluorescent paint marks and thin slices in the pavement tag the spots for planned excavations, while troughs mark ongoing construction.< You should see the intersection of Wall and Water in NY City right now. It was just paved over, by the way, but that doesn't stop progress. Those fluorescent markings create the illusion of some kind of surreal 3D game board from the windows above. Imagine a 25,000 square ft. battle plan blowup on blacktop, with pastel colored fluorescents. No, make that a gridiron sketch by an offensive coach suitable for an IMAX screen presentation, showing penetration strategies to each building specifying each carrier's path to a targeted building's "sleeve." Flagstone and marble sidewalk panels are marked where they will be uprooted, and evnetually repaired. Yesterday (that's right, Saturday) I visited the office for a few things and witnessed Con Ed's contractors pouring cement into a series of work boxes and stratifications for steam cavities (nodes and joints) which lie adjacent to some of the major carriers' person holes (hey, I try) which are slated for entry and/or excavations. Let's see. How high will the temperature get down there next to these steam fittings? What about the variable pH factor in the soil beneath ? Are there any potential petroleum product droppings in this neighborhood that can ooze down below to affect the build materials in an adverse way? What's the rodent population like down there? Rats on Wall Street? (And no, I'm not referring to the two legged type. C'mon now...) What kind of conduit material do I select for such a hostile environment? Fiber glass? PVC? Stainless steel? Titanium? How about encasing each run in concrete two feet down AND using stainless steel, as well? That should keep the rodents out, at least. Right? All comments are welcome.
