Contract drawing DP-503, in the description of the Phase 1 scope of work, in Item 1, refers to a drawing #8469-30-4 prepared by the San Francisco Port Commission. Please make that drawing available to the bidders.

Included in amendment 0004

Answered on October 11, 2011: 5:20pm.

Please provide details of size and grade of existing rock fill in front of and below the existing seawall.

The rock dike and seawall were constructed in the early 1900’s and there are no As-Build drawings. However, we have posted design drawings that give a pretty good idea of their construction. Refer to Question #7

On page 15 of 393 of the specifications, in Note 1 at the top of the page, the requirement is stated that "Prices must be submitted on all individual items of this bid schedule." Does this include the 3 items starting with 0000 on page 8 of 393?

Bid items start with Bid Item #0001

Does the scope of Bid Item Number 4 - Demolition of the Pier 36 Building also include the Pier 36 Building Hazmat Abatement that is the subject of OPTIONAL Bid Item 0008? I do not believe that building could be demolished without Hazmat Abatement also being performed.

There is a possibility that HAZMAT abatement be contracted out through a separate USACE contract and we will know for sure one way or another if that is the case no later than 28 OCT 2011. For the time being on this contract we are considering HAZMAT abatement as an OPTION. An update to this question will be made available no later than

28 OCT.

Please confirm that Bid Items 1, 2, and 3 are only to include that work necessary to support the BASE BID items, and should NOT include any of the work required to support any optional items, since it is apparently unknown whether any optional items will be awarded. How will that support work required for any optional items that are awarded be paid for?

The bid schedule was amended to include two additional Line Items applicable to the Optional Items as follow: Line Item 0014 Safety and Traffic Control for Optional Items and Line Item 0015; Environmental Protection/Monitoring for Optional Items.

Please confirm that Optional Bid Item 0011 defines "Marginal Wharf" as only the portion of the wharf supported by the piles/caissons, and not the piles/caissons themselves.

Item 0011 refers to all structural portion(s) of the “marginal wharf” including deck, beams and other supporting structures except piles and caissons. See also, items 0012 and 0013.

Answered on October 11, 2011: 5:20pm.

Please review and confirm that the scopes of work in Optional Bid Items 11, 12, and 13 do not overlap and are mutually exclusive.

The marginal wharf is composed of structural deck and supporting structures, plus piles and caissons. Bid items 0011, 0012 and 0013 don’t overlap.

Is there a Hazardous Materials Survey for Bid W912P7-11-B-0005?

Yes. See Document titled “Pier 36 – HAZMAT Survey Report (SEP2009)” by Winzler and Kelly. This document was uploaded in Amendment #2.

Answered on October 19, 2011: 4:20pm.

15 Was the site visit a mandatory requirement to be able to bid this project?

No it was not mandatory.

Answered on October 17, 2011: 12:20pm.

16 Per addendum #3, is the following a requirement for the prime contractor or subcontractor performing the water based demolition? Can a subcontractor qualify for the marine experience under a prime contractor?

Yes, a subcontractors experience can count .

Answered on October 17, 2011: 12:20pm.

17 Is this marine demolition experience mandatory? Is it mandatory only for marine demolition on the project? Most of the work could reasonably be performed from the existing deck minimizing the need for marine equipment/experience.

Marine demolition experience is necessary regardless of planned demolition method. For purposes of this solicitation, marine demolition is demolition of a structure located above and/or under water. The pre-award survey will be changed to reflect this definition of marine demolition.

Question 1: Spec. para. 3.2 on page 149 relates to providing office facilities for the COR, but only IF there is no office space is nearby. Since it should be known at this time whether such office space is available, please remove this uncertainty from the specifications. In the event office space IS available, as would seem to be the case, would the requirements stated in OTHER REQUIREMENTS of that paragraph still apply?

Update: The contractor has to find office space within the staging area or rent/lease space in the open market. The office has to be equipped as indicated whether the office is a trailer or regular office space. For leasing space in the project staging area call: POSF, Elliott Riley (415) 274-

QUESTIONS & RESPONSES

Question 2: Page 180, paragraph 1.8.I states that “the Contractor shall provide and place bracing and shoring to prevent movement or damage to structures and improvements which are to remain.” See also similar wording on page 179, Paragraph 1.5, in the first subparagraph, and also the inclinometer requirements in the last paragraph on page 178. It is apparent from the inclinometer requirements that the Owner anticipates that movement of the seawall is a possible result of the demolition required by the contract. Please confirm that the Contractor is not responsible for "providing and placing bracing and shoring to prevent movement or damage" to the seawall and that any such work would be beyond the scope of this contract.

CLARIFICATION OF INTENT: No bracing of the Seawall is required per the current specifications. However, if sections of the seawall become unstable and shoring and bracing becomes a necessity, clearly that would be a change condition.

NOTE:

A structural analysis was conducted to estimate the stability of the seawall for a condition prior to and following the removal/demolition of the Marginal Wharf; and the analysis show that small displacements of the concrete seawall may be detected. Consequently, there is the requirement of installing inclinometers and monitoring potential displacements that may occur prior to and during demolition of the marginal wharf. Demolition work will be halted if the displacement becomes excessive as defined by the Specifications 02 41 00 DEMOLITION, Section 1.3.13 Concrete Bulkhead Monitoring During Demolition.

Answered on October 19, 2011: 4:20pm.

Question 3: On page 180 of the specifications, the last paragraph on the page refers to removing the top 2’-6” of seawall along the length of the project, “as indicated on the project drawings”. Where is that indicated? As far as B/DP501, the detail takes you to 2/DP-501, which only requires the beam and deck to be sawed off at the front face, no demo at the top of the wall. On DP503, that section does mention removal of the top two feet of the seawall, but says it is NIC. Please confirm removing the top of the wall is NOT part of this contract.

Page 180. Specification 02 41 00, DEMOLITION, Section

1.9 Seawall Demolition. This section is in ERROR. Detail 2

on DP-501 is correct. Removing the top of the existing seawall IS NOT part of this work.

Answered on October 19, 2011: 4:20pm.

Question 4: Amendment 4, in item 14, says the bid is due “at 1 pm (est)”. Please clarify.

The bid due date time is 1:00pm (pacific coast time) on the 27th of October.

Question 5: On page 18 of 393 in the specifications, “Clauses Incorporated by Reference” includes clause “52.232.15 Progress Payments Not Included”. Since other portions of the specifications clearly include provisions for progress payments, please remove this clause from the list.

Concur … will be removed in an upcoming amendment.

QUESTIONS & RESPONSES

Question 6: I do not find in the specifications where the amount of the bid bond is stated. A bid guarantee is clearly required by paragraph 13.B of the Solicitation Form 1442, but what specific form and amount of guarantee is required?

See question 4 on this document and amendment 0003.

Question 7: Longshore and Harbor Workers’ Insurance would certainly apply to work on this project, and any contractors would need to have such coverage. Yet the insurance specifications on page 321 do not include it. Please review this insurance coverage requirement.

See amendment 0005 for insurance requirements.

The insurance specifications on pg 321 are solely for the Encroachment Permit from the Port of San Francisco, and do not reflect the insurance requirements for the overall project.

Will there be another opportunity to walk the project?

There is nothing scheduled or planned for another site visit.

Is there any further detail on the asbestos roofing materials, specifically what type of roofing material is found on the roof and its thickness?

No further information is available. All information is included in the HAZMAT Survey. See question 14 of this document.

Answered on October 19, 2011: 4:20pm.

Is there any data available on what the weight limits of Pier 36 are? Specifically Is there any data currently available that would inform the demolition contractors of what the weight limit would be for the equipment needed for the building demolition scope of work?

There is no data available regarding the weight limits of Pier 36.

Answered on October 19, 2011: 4:20pm.

Is there a difference between a wharf and a pier?

We have wharf demo experience … would that qualify as pier demo?

In terms of demolition experience, wharf demolition will qualify as pier demolition, and vice versa. Both structures are marine based and, as such, fall under marine demolition.

Answered on October 19, 2011: 4:20pm.

1) Regarding Concrete Rehabilitation, on page 291 of the specifications, Par 1.5.F refers to "Subsection 3.1.B". Where is that subsection located? Please Which findings does the contractor has to provide from the exploratory core hole drilling?

The correct reference is Subsection 3.1.2 B, located on page 295. “ Core 4 in. diameter exploratory holes where shown on the contract drawings or where indicated by the Owners Representative”

AS OF: 21 October 2011 0100 Page 7 of 10

On specification page 292, under Par 1.6.3 - Testing Services, the first sentence states: “The Port will engage an approved testing lab to perform all Phase I crack repair exploration required to determine scope of repair”.

a) Does this mean that the exploratory core hole drilling depicted on drawing DP-503 will be performed by the testing lab and is NOT the responsibility of the contractor?

b)If so, please disclose the name and role of the testing lab and the estimated time it will take to complete the exploratory coring of the seawall and verification of a previously repaired crack indicated in Par 3.1.1

This wording as noted on left is incorrect.

UPDATE. The Contractor will be responsible and shall provide all crack repair exploration required to determine the scope of repair.

Also, please refer to Sheet DP-503, Phase 1, Exploration and Repair of Existing Crack ( on Seawall)

Par 3.2.4 – Placement – Item E; Please indicate how the contractor will be reimbursed if the actual grout quantities pumped exceeds the theoretical quantities calculated from the dimensions shown on drawing DP-503.

Pending …

On contract Drawing DP-003: Please confirm that the piles depicted on the Pier 34 location are not part of this project as is suggested by the staging limits of work shown on the drawing.

The group of piles depicted on the Pier 34 footprint as shown on Sheet DP-003 are non-existent. However, there are 10 Caissons supporting the marginal wharf within that footprint that are part of the project and ought to be removed. See Bid-line-Item 0013 and sheet DP-113 for clarification.

Bid Item No. 0009 is for the removal/demolition of timbers including standing and submerged piles and any collapsed pier structures in the "debris field" shown on drawing DP-112. Since virtually all of the items to be removed under this bid item are submerged, the amount of work is unknowable and cannot be quantified by the bidding contractors.

Since the work cannot be quantified the bidders cannot accurately price it and the Owner will be set up for disputes after the job is awarded. To create parity in the bids, we suggest you create an allowance item with a set bid price that would later be measured and paid for on a force account basis to cover the actual costs incurred plus allowed markup.

For bidding purposes the quantity to bid on line item 0009 will be Tons and for uniformity use the following estimated quantities to bid on:

a) 720 Tons of Timber

b) All other debris; 1420 Tons

Refer to Bid- Line-Item 009.

AS OF: 21 October 2011 0100 Page 8 of 10

Concerning drawing DP-503, Phase 2 – Stage 1 and Stage 2: Please clarify the number of vertical 4” diameter core holes to be drilled. The plans call for 225 holes total, as seen in Phase 2 – Stage 2 item 2.A. However, over the 260 lf of crack repair (per Phase 1, item 4.b) that would result in holes at 14” on center, instead of the 21” to 36” spacing called for and shown the table in items 1 and 3 of Phase 2 Stage 1 work. How did you get 225 holes?

10-20 2058

Amendment 3, on page 1 of the Pre-Award Survey, in item A, refers to “Schedules A-D (Attached).” I do not believe those schedules were attached?

In Amendment 3, Items B and C of the Pre-Award Survey requires detailed confidential financial data to “be submitted with your bid or your bid could be considered non-responsive.” Many private companies will object to providing such confidential information with the bid, which has certainly not been required on other Corps of Engineers projects. 100% performance and payment bonds are required of the Contractor, which should ameliorate the concerns of the awarding agency.

This contractor will likely choose to not bid the project rather than provide this financial information, and suspects others will do the same.

Please remove this requirement for providing financial information.

In order to accommodate further inspection of the building to be demolished, please schedule another opportunity, preferably on Monday morning, for contractors to visit the site.
