Colum n6 ROUND #2 CHOH 151201 Question

Answer

In the plan sheet series C2.xx there are various plans sheets that identify trees for removal but do not identify the size of the tree. Please provide sizes of these trees..

Additional tree size data has been added as a redline to the "Revision 2" plans on the Sheet C2.XX series. These are provided along with this response. Of note is that the diameter of trees scheduled for demo and those anticipated to remain were both included in the redlined "Revision 2".

Section 01 31 00 1.9.B details the permits that the Government has procured and specifies that the contractor shall adhere to the terms and provisions of these permits. Please provide copies of these permits so the contact and bid responsibly.

Permit applications are ongoing with USACE & MDE. Any substantial changes in scope that result in conditions/constraints provided with the permit authorizations will be addressed per

52.243‐4 CHANGES.

Section 01 11 00 ‐ 1.7.C.2 states, "This section of the Potomac River is classified as a Use I Waters. MD‐DNR prohibits in‐ stream work within Use I Waters during the period March 1 through June 15, inclusive, during any year unless MD‐DNR issues a waiver. The NPS is currently filing a request for an instream waiver from MD‐DNR. NPS does not warrant or guarantee that a waiver will be granted."

This vague and will cause a large dissimilarity in costs among bidders if all do not use the same ideology, we suggest that this language be modified to the following:

DELETE: "NPS does not warrant or guarantee that a waiver will be granted.

ADD: "Bidders shall prepare their bid assuming that the MD‐ DNR will issues a waiver. If the MD‐DNR rejects the request, any additional costs will be addressed per 52.243‐4 CHANGES."

Concur, subject paragraph was edited to "a.To protect aqua c species, MDE prohibits in‐stream work during certain times of the year as determined by the classification of the stream. This section of the Potomac River is classified as a Use I Waters. MDE prohibits in‐stream work within Use I Waters during the period March 1 through June 15, inclusive, during any year unless MDE issues a waiver. The NPS has submitted an instream waiver and submitted to MD‐DNR and MDE. Coordination with these entities indicates that the waiver will very likely be granted. For bidding purposes, the contractor should assume that MDE will be issuing a waiver. If the waiver is not issued, then any impacts to the contract will be addressed under 52.243‐4 CHANGES." Revised section 011100 has been provided with this response.

For the Wall Extension at Station 21+69 ‐ 21+90: is it the government’s intention to place a portion the 57 stone below the water table?

As shown on Sheet S1.2, free draining stone is required to be placed under the water line within the 1H:1V line of influence projected up from the toe of the stone wall. However, due to constraints with placement of #57 stone below the water line, Detail 1 / Sheet S1.2 was revised to require that "IN REACHES

REQUIRED TO HAVE FREE DRAINING BACKFILL PLACED BENEATH

WATER, BACKFILL WITH WALL STONE MATERIAL (SALVAGED OR

NEW) BELOW THE WATER LINE. PACK VOIDS TIGHT WITH HEART

STONES IN SIMILAR MANNER TO WALL CONSTRUCTION." Redline revisions were added to sheet S1.2, and provided along with this response
