To Bid Documents for:

RUDEE INLET OUTER CHANNEL MAINTENANCE DREDGING

Bid No. PWCN-14-0126

Date: November 21, 2013

To All Concerned:

The original Bid Documents, for Bid No. PWCN-14-0126 of the City of Virginia Beach are amended as noted in this Addendum No. 1, and the Addendum shall become part of the Bid Documents. Bidders must acknowledge receipt of this Addendum during the bidding process by notation on the Bid Proposal/Contract Forms when submitting proposals.

QUESTIONS & ANSWERS (Q&A):

The following questions were received about the solicitation:

Question #1

Is an ABS certified hydraulic dredge required for the project? Please note that most of the dredge area lies outside of the Boundary Line, the line outside of which an ABS certified dredge is required.

Answer

Compliance with USCG and marine regulations is required. The OWNER does not warrant the location of the Boundary Line, nor has the ability to control which level of certifications are necessary from authorities of jurisdiction.

Question #2

Is it up to the contractor to select the most practical pipeline route and beach landing location?

Answer

Yes, taking Contract Documents and Permits into consideration.

Question #3

What is the Engineer’s Estimate and/or City’s Budget for the project?

Answer

The engineer’s estimate and/or City’s budget for the project is not available at this stage of the procurement process.

AD-1 of 9 November 21, 2013

Question #4

A lump sum price for dredging is extremely unusual for the industry. This payment format places all risks for shoaling that may occur, as well as survey inaccuracies for the supplied hydrographic survey, solely on the Contractor. The Contractor, in turn, must include in his price contingencies to account for these risks. We respectfully request that the payment format be revised to a), include a lump sum mobilization and demobilization bid item, and b), a per cubic yard unit price dredging bid item. The per cubic yard dredging bid item can be paid for by pre/post survey of either a), Rudee Inlet or, b), the beach template.

Answer

Section 102.04- Schedule of Prices – 2 of 22 has been revised to include unit price for mobilization/demobilization and dredging, and is attached with this addendum #1.

Question #5

The current Specification states that the Owner will perform pre/post surveys of Rudee Inlet for acceptance and that contractors are allowed a beach fill tolerance of +/- 0.5 ft. Is it the City’s intention to base acceptance upon, a), clearing of Rudee Inlet to the required grades, or, b), filling the beach template?

Answer

Section 901, Paragraph 2.5.7, Page 12 of 14 has been revised as noted below in this addendum #1. Acceptance is based on Section 901, Paragraph 3.0, Page 14 of 14.

Question #6

Are contractors expected to place the dredged quantity uniformly down the entire 3,500 ft. of beach or will beach placement end when the available quantity from Rudee Inlet is exhausted?

Answer

Beach placement will end when the available quantity from the inlet is exhausted, the goal is to dredge the channel, not build a beach. But the beach building needs to comply with the cross section. Refer to Project Drawings Sheet No. 3 of 4 and 4 of 4, attached with this Addendum #1.

Question #7

What are the anticipated cubic yard / linear foot for the beach placement?

Answer

Information is not available – refer to Typical Beach Fill Section of Project Drawings Sheet No. 4 of 4, attached with this Addendum #1.

AD-1 Page 2 of 9 November 21, 2013

Question #8

The plan view drawing of the beach template and the typical cross section of the beach template do not correlate to one another. The plan view drawing is not showing the permitted seaward edge of berm at 300 ft. like what is shown on the typical cross section. Please clarify.

Answer

Construct beach fill as shown on the Typical Beach Fill Section of Project Drawings Sheet No. 3 of 4 and 4 of 4, attached with this Addendum #1.

Question #9

When was the last dredging project at Rudee Inlet?

Answer

Rudee Inlet was last dredged by Norfolk Dredging Company (Charleston) during period of April 3, 2010 through April 10, 2010 for the Outer Channel Deposition Area and by United States Army Corps of Engineers (Merritt) during period of June 16, 2013 through June 20, 2013 for the Entrance Channel.

Question #10

We respectfully suggest that the overdepth quantity be included in the advertised quantity.
