Section 17.

and Drawing

SB004

Please Clarify the intentions regarding the Time-of-Year Work (TOY) Windows Restrictions outlined in the Add #2 permits versus the (TOY) Restrictions outlined on drawing SB004, note 1 under "Turbidity Curtain General Notes," as they conflict with each other. The TOY outlined in the Permits would have severe adverse affects to the project cost and schedule, while the drawing language is much more favorable to the project.

See response to PPI No. 20, the window listed on SB004 requires the use of Turbidity curtains and turbidity monitoring from Feb 1 to May 31 each year for in-water turbidity producting work including pile driving, pile extraction, and bottom disturbing activitites in an effort to minimize impacts to fish spawning and juvenile development.

51 SB601

On SB601 the minimum pile tip elevation is shown to be below the estimated top of competent bedrock for many of the king piles.

Sheet note 1 states that "Steel pipe piles must be driven to minimum tip elevation and achieve allowable bearing capacity to be considered acceptable. Minimum tip elevation is required to establish lateral stability. Estimated top of competent bedrock elevations are provided for reference only." What is the required course of action if refusal on bedrock is encountered before reaching the minimum tip elevation?

What is listed on SB601 as "top of competent bedrock" per the geotechnical borings is actually top of "highly weathered bedrock", believe the greatest embedment will be near LB-38, which is above the elevation of "Bedrock" as noted in the borings with a Rock Quality Desigination (%) which for this boring starts at 60%, for additional information see the geotechnical borings, the point of the "indicator" or Bulkhead Test piles is also to establish drivibility along the lenght of the bulkhead, as noted on sheet SB601.

H 1.1.b

Regarding the time period of up to 365 calendar days after contract award to award the option items.

There are concerns waiting up to 365 calendar days will have impacts on the base contract work.

Certainly options 5 (underground objects), 6 (undercut), 7 (underwater) will need to be awarded as they are encountered in order to progress the base contract work.

Waiting to award options 1 (boat repair bldg) and 2 (Hazmat container) will impact the underground utility work and site civil work. Typically underground utility installation is an early work activity. The contractor will want to install all the utilities, then work to improve the site after the utilities are installed. Delayed installation of option 1 and 2 utilities will impact the base

Please see Amendment 0006- Price Proposal Form Revision 3.

Government reserves the unilateral right to award CLINs 0003, 0004, and 0006 (Option Items 1, 2, and 4) to the Contractor at the proposed price within 120 calendar days after the contract award. The Government reserves the unilateral right to award CLINs 0005, 0007, 0008, and 0009, (Option Items 3, 5, 6, and 7) and CLINs 0014, 0015 (Option Item 12, 13) to the Contractor at the proposed price within 365 calendar days after the contract award.

contract site civil work in place.

Delayed installation of the option 1 and 2 structures will impact base contract site civil work finishes.

Waiting to award option 4 (floating dock system) will have similar base contract impacts as options 1 and 2, as well as the contractor assuming the risk of fabrication and delivery escalations, and the remobilization of equipment and crew to install the work.

Therefore, the contractor recommends NAVFAC be prepared to evaluate and award options 1, 2 and 4 with the award of the base contract, and NAVFAC be prepared to award options 5, 6 and 7 as they are encountered.

Please confirm.

Foundation Notes

Drawing SB003 Note 9 indicates for the purpose of bidding, the contractor must anticipate encountering obstructions for (10 piles) during driving of steel pipe piles. Spec 31 62 16.13 under

3.2.8.1 Obstructions indicates if

obstruction is encountered within 5 feet of the ground surface to prevent driving and cannot be cleared then pile must be pulled or cut off at no cost to govt and if encountered more than 5 feet below ground surface and the obstruction cannot be cleared by drilling or spudding, the pile is cut off and paid for as if a completed pile. In either case a pile is installed and paid for as completed. Then under SB003

See Amendment 0006 - Continuation pages, and Attachment H - Price Proposal Form R3.

In summary, a line item for obstruction has been added to the price schedule, and the pipe piling specifications have been modified to clarify the process with dealing with obstruction. Specifically (1) If an obstruction is encountered within 5 ft, pull the pile and redrive at no additional cost. (2) if an obstruction is encountered below five ft then price the mitigation measures listed on SB003 on the Price Proposal Form. Note changes in under Foundation Note 10 part B.

the last sentence indicates at the contractors option the pile encountering the obstruction may be abandoned and new steel pile installed at required offset location at no additional cost to the government. This is contradictory to the specification since pile cutoff and and reinstallation when obstruction is encountered greater than 5 feet below ground surface is paid for as a completed pile per Section 31 62 16.13 secton 3.2.8.1.

(1) Please confirm and clarify for purpose of bidding the contractor should include cost for 10 piles encountering underground obstruction within 5 feet of the ground surface. (2) Confirm contractor for purpose of bidding should not include costs of encountering obstructions greather than 5 feet below the ground surface since in that condition (greater than 5 ft) the pile cut off is paid for as a completed pile with replacement pile installat at location indicated by CO and also paid as completed pile.
