Scaffolding Contractor: <br />1. You have identified the south wall as the location of the access to the low roof on the <br />west, is there any other location this can be placed? This also applies to the location <br />to place equipment and scaffolding on the roof. <br />2. If the service lines from the pole were removed, can your scaffolding be located such <br />that the existing conduit going up the wall is not a danger? This conduit is most <br />likely housing copper lines that carry 240 volts, but we need to verify that. <br />Demolition Contractor: <br />1. Where does your trash chute need to be located? Can you take the demolished brick <br />down the existing elevator pits and out the doors of the building? <br />2. How far does any live conduit need to be from areas that you are working? Can you <br />demolish the west wall if the conduit going up the wall on the corner of the south <br />wall is live? <br />3. Do you have a feel for what materials on the west wall, inside or out, have asbestos <br />and will have to be abated during demolition? (ie, what about the plaster on the <br />walls of the penthouse ?) How long will an asbestos survey take on those areas <br />which need to be demolished? <br />4. Do you have a feel for abatement needed to run a conduit up a chase inside the <br />building? <br />5. Do you have the capabilities to inspect the existing cast stone parapets to determine <br />if any are in imminent danger of falling? Can this be done by a lift? <br />Hoofing Contractor: <br />1. How long if all the equipment were off the roof for you to re-roof the building? <br />(about 5500 square feet — 75 ft to top of parapet). Assume 9" of rigid insulation. <br />2. How long would it take to reroof if you had to do it in two phases so the towers could <br />be moved around? <br />3. Can you work on part of the roof with the equipment live on the other part? <br />®ncor: <br />1. Where does the existing service enter the building to service just the building and <br />not the cell towers? Can that service be used for the cell towers? <br />2. Can service to the cell towers be relocated to somewhere other than where is it now? <br />(coming from the pole in front of the Barber Shop) <br />3. Can service be underground to the cell tower conduit? <br />4. How many volts are in the service line and in the conduit going to the roof? <br />All be prepared to also discuss timelines, schedules and critical paths. <br />Page 1 2 <br />
