Section A1 on SS301 shows the existing mudline to be below the -22.0’ elevation.

Please clarify which is correct.

Refer to Amendment 0006;

Summary of changes. The existing mudline will graphically be shown above the bottom of fascia at EL -22.00 NAVD88 with a note that indicates the elevation varies and to refer to the dredging plans for existing mudline elevation. Refer to revised Drawing

SS301.

307 CN101

& SS301

If elevation on CN101 is correct, please clarify if the contractor expected to excavate / dredge this 10’ of material prior to combination wall installation. The prewelded studs will be damaged, if driven through the mudline.

Where the existing mudline along the CEP-176 alignment is higher than -

22.00 NAVD88, it is anticipated that

select dredging will be required at these specific locations after installation of the new steel pipe/sheet pile combi-wall to facilitate construction of the concrete fascia.

308 CN101

& SS301

Please confirm the existing North Face bulkhead can handle being dredged to a - 23’ elevation.

The 1943 original as-built construction drawings for CEP-176 are poor quality and unable to be read. For reference, subsequent repair drawings from 1946 and 1982 appear to show the mudline adjacent to the existing bulkhead as -

10.0 Mean Low Water (MLW) and

sloping down to the dredge depth.

Repair drawings from 2000 and the hydrographic survey for this project show the existing mudline adjacent to the existing bulkhead at the western end of CEP-176 deeper at -20.0 MLW.

The difference between MLW and NAVD88 vertical datum can be found on G-005. Localized dredging associated with debris removal to facilitate installation of the conbi-walls will be allowed down to elevation -20.0 MLW with prior approval of the Contracting Officer.

309 CN101

& SS301

If excavation / dredge is allowed prior to installation of the combination wall on the North Face, please clarify if the contractor will be able to dispose of the material at Craney Island? This excavation quantity is near 10,000 CY.

Details shown on Drawing SS536 remain applicable.

312 SS501 From C1, please provide a detail on the transition of the fascia concrete from elevation -22’ to -6’ between Pipe Pile Bent 97 and 98. We cannot determine where that transition occurs.

Refer to Amendment 0006, Summary of changes. See revised drawing SS501. The overall depth of the precast concrete fascia panel at CEP-176 was established at -22.0 NAVD88 to adequately mount the heavy weather mooring FRP backer wall shown on Drawing SS551. Therefore, a bottom elevation of -22.0 NAVD88 is not needed at CEP-102 or underneath Pier

3. As such, the precast concrete fascia panel is intended to end at the northwest corner of CEP-176 near pipe pile #97. The bottom of the concrete fascia makes a transition from elevation -22.0 NAVD88 to elevation -6.0 NAVD88 at the alignment of the front face of pipe piles on the combi-wall running along the north face of CEP-

176. Contractor to form the south face of the fascia at the transition between elevation -22.0 to -6.0. For additional information, see C1/SS501 &

A4/SS501.

Note 2 on drawing G-122 states that the transition from phase 2 to phase 3 corresponds with the substantial completion of CEP-176 structural work where Phase 3 includes the allowable dredging. Please define more clearly what is considered structural completion of CEP-176. Does this include fascia panels?

Note: it appears the precast fascias are below existing mudline in some of the areas that would lead us to be believe some dredging is required before the fascias are set. Please clarify.

Substantial completion must include installation of the new steel pipe/sheet pile combi-wall, construction of concrete fascia, and construction of the CEP-176 relieving platform prior to full-depth dredging activities in the basin. Where the existing mudline along the CEP-176 alignment is higher than -22.00 NAVD88, it is anticipated that select dredging will be required at these specific locations after installation of the new combi-wall to facilitate construction of the concrete fascia.
