With regard to Solicitation W912P7-16-B-0004

- Redwood City Harbor Channel Maintenance Dredging Project, San Mateo County, California, please clarify the following issue:

If dredging were to continue beyond November 30, 2016, and there was a need to dispose of the dredge sediments at an upland disposal site would the materials being dredged from Reaches 1-5A be considered "Cover" or "Non- Cover."

If dredging were to continue beyond November 30, 2016, and there was a need to dispose of the dredge sediments at an upland disposal site would the materials being dredged from Reaches 5B be considered "Cover" or "Non- Cover."

The material in Reaches 1-5A is considered suitable for cover at all of the currently permitted upland sites.

The material in Reach 5B is considered suitable as non-cover.

Please let confirm that it is acceptable to use the SF24 with the 7/31/16 expiration date for the 8/1 bid referenced above.

OMB Control Number: 9000-0045 Expiration Date: 7/31/2019

3.2.4.2 Reaches in Section 35 20 23 states, “The

project area has been divided into reaches as presented in the project plans. The Contractor shall not dredge in a reach without the written approval of the Contracting Officer Representative. Written requests to begin dredging in a reach shall be initiated by the Contractor and shall include a copy of the request for Reach Acceptance Survey for the previous reach, if there is a previous reach.”

a. Should weather or sea conditions, such as those defined in 3.6.2. a. of Section 35 20 24, prevent disposal activities at SF-DODS while dredging is ongoing in Reach 5B, would the USACE consider allowing the Contractor to dredge in another reach with disposal at SF-11 to prevent significant weather delays?

Dredged material from Reach 5B is not suitable for in-bay disposal at SF-11.
