Question # Question or Comment Government Response

The Scope of work calls for Dual 96 strand trunks, One in a counterclockwise fashion to buildings 171, 277, 294, and 322.

As well as the other trunk in a Clockwise fashion to buildings 19, 28, 78, and 210. In the diagram you provided in Amendment 0002 it looks like you want home runs from building 21 of (8) 24 strand SM fiber optic cables. Or is (2) 96 strand SM fiber optic cables Mid-sheathed and terminated at each Buildings fiber enclosure location the plan?

The intent is to have (2)96 strand SM fibers coming from building 21 that will both run into the first manhole. From there it will split paths until it reaches the next manhole and/or conduit to the adjoining buildings. We need 24 fibers going to each building past building 21 allowing it (building 21) to act has the hub with all other building to act as spokes.

2 How many splices are we splicing per building for the fiber optic?

There will be 24 splices per interior building (except BLDG 21). At BLDG 21, we will have the 192 in 21LC1 (LAN closet) and another 24 in the electrical room (Verizon 21-inch rack). If a separate 24 strand needs to passthrough a building, there will be an additional 24 strand splice in the passthrough buildings. Number of passthrough buildings are TBD.

Regarding the Q&A and the documents, I do not see how much 96 strand fiber will be needed to get to the designated manholes where it will split into 24's. Can you provide any clarity on that please? Also do you by chance have a building layout map?

The amount of 96 strand needed is not definitive as the cable paths underground are still to be determined somewhat. At this time, it is believed that there are 2 manholes, so we will need 2 runs of 96 strands to the first manhole. Past that it is possible that we can reduce the strands down to a combination of 48 and 24 strand.

Assuming the pathway is individualized to each building with no passthroughs. If some of the buildings will need to passthrough to get to another, a 48 strand will need to run

Amendment A0004 to the first building to be split off into 2-24 strands where the second 24 continues to the next building. It is not clear if there are runs that pass through multiple buildings currently. If that is the case, we will need a 48 and a 24 ran into one building with the intent to continue through the buildings until each building has 24 strands.

Footages from BDLG 21 to each building:

322 to 21 = 845 19 to 21 = 295 171 to 21 = 675 277 to 21 = 745 210 to 21 = 1050 78 to 21 = 845 28 to 21 = 400 294 to 21 = 950
