Question 1.

Bid Item for tension connectors (Section 00010) PS 1-4 - Please create unit item for tension connectors for pilings.

Response.

No, tension connectors are to be paid under “Furnishing Piling H, HP 14x73” and “Furnishing Piling H, HP 14x89”. See Spec section 31 62 16.00 12 paragraph 1.2.2

Question 2.

TRS Sheet Pile Tip Design (015300.0212, P.4 Paragraph 1.5.2) Although the TRS is referenced in both the plans and specifications as "Contractor Designed", both give minimum tip elevations for the TRS. Specification Section 01 53 00 .02 12 page 4, paragraph 1.5.2, states the "minimum sheet pile tip is elevation -60.0", while the plans for PS 1 (sheet G-16) and PS 2 (sheet G-15) state -48.1. PS 3 (sheet 2-25) and PS 4 (sheet C-05) state -

60.0. What elevations apply?

Response.

Pump Station 1 and 2 will be amended to show a "minimum sheet pile tip is elevation -60.0"

Question 3.

Soil (Sections 015300.01 and 015300.02) Reference Specification Sections 01 53 00.01 and 01 53 00.02 and soil boring details - The soil parameters for TRS and TFP design indicate impervious clays for a significant depth. Recent experience at some station locations indicate substantial pervious soils will/may be encountered.

Should the concept shown by the USACE of a single wall across the canal not allow for dewatering, would the USACE consider such a condition a change and result in a subsequent contract modification?

Response.

No, a contract modification will not be issued. The TRS dam shown on the plans is a suggested concept. The soil data provided is a general representation of the conditions where the TRS will be constructed, with the final TRS dam and dewatering designs being the sole responsibility of the Contractor.

Question 4.

Use of Spiral Welded Pipe (Section 33 05 00.00 12-2.11) Specification section 33 05 00.00 12 - 2.11 states in the last sentence of the first full paragraph that "Spiral welded pipe will not be allowed." This is in regards to all piping 36" - 96" in diameter as listed. I am hoping that excluding spirally welded pipe was an error and spiral welded pipe will be allowed on the subject project. Spiral welded steel pipe is the manufacturing

W912P8-09-R-0065 method of choice in large diameter pipe across the country and is much more economical than pipe from plate in the large diameters. This issue was brought to my attention late yesterday afternoon and I wanted to get clarification on the specifications. We would like to participate in the bid but as written would not be able to quote because of the clause.

Response.

The specs will be amended to allow both straight seam and spiral welded discharge pipe for both the temporary and permanent features.

Question 5 "Some of the cast iron gate sizes are non standard for cast iron. (no question on fabricated gates).

Can we quote roller gates in lieu of the cast iron sizes or can we adjust the cast iron sizes to standard sizes?"

Response:

Please bid the cast iron gates as shown on the plans. Roller gates will not be allowed.
