[sudo-discuss] Re: Omni Roof leaks status - CCL-urgent

CCL: has multiple significant leaks. * IMO, a ccl member if at all possible needs to come on-site stat to assess lab & equipment if they haven’t already. * in the event the sump pump is at all inactive or affecting flow of ccl drain, I cleared away items in front of access hatch in NW lab. ** If possible I would like all shelving / items in NW corner of the NW lab temporarily removed asap in case the sump pump itself needs to be accessed / assessed, which is presently blocked by interior siding / shelving here (predating Omni’s possession of premises.) * * sump pump function to me as a layman looks unrelated to roof drain flow over CCL, but roofer may want to check this to be sure. * if it can’t be feathered up, west edge of building may need additional roof drains. Water collects here and flows too slowly to NW roof drain, the indent in the roof here appears to lead to thicker layers of elastomeric collecting here which it turned out did not have enough time to cure before the weather turned. Ballroom: three leaks, one on main floor (severity: medium), one on east mezzanine (medium), one on south mezz (mild) Roof drainage: - 48th st drain near corner door: is flooded / partially blocked at 2nd-story air gap, resulting waterfall down side of building. Water is flowing off roof but itappears that roof drainage is insufficient on this side and an additional drain must be added. Termination for this drain at curb: I just noticed is only about 20% of drain orifice, significantly reducing flow rate of bottom portion of drain. To fix, either the street must be dug out a bit around opening to unblock, or the sidewalk must be trenched and the horizontal drain level raised. - 48th st drain closer to ANV room: drainage works but appears pretty slow; & termination at curb is 50% of orifice. - 48th st drain near trash room (from ccl): flows, but w/ 60% clear orifice at curb face The rest of omni from a cursory check appears leak-free.
