BID SECURITY

A. A Bid must be accompanied by Bid security made payable to OWNER in an

amount of 5% of Bidder’s Grand Total in Base Bid and in the form of a

certified check or bank cashier’s check, or a Bid Bond issued by a surety

meeting the requirements of OWNER.

B. The Bid security of the Successful Bidder will be retained until such Bidder

has executed the Contract Documents, furnished the required contract

security and met the other conditions of the Notice of Award, whereupon the

Bid security will be returned. If the Successful Bidder fails to execute and

deliver the Contract Documents and furnish the required contract security

within 10 days after the Portage County Board Meeting on May 18, 2023,

OWNER may annul the Notice of Award and the Bid security of that Bidder

will be forfeited. The Bid securityof other Bidders whom OWNER believes

to have a reasonable chance of receiving the award may be retained by

OWNER until the earlier of seven days after the Effective Date of the

Agreement or 61 days after the Bid opening, whereupon Bid security

furnished by such Bidders will be returned.

Question

Q1. Are you looking for a 5% or 10% bid bond? Also you aren’t looking to get a payment and

performance bond at the time of bid are you?

A. We are looking for a 5% bid bond based on your Grand Total of the Base Bid. We are looking to get

the payment and performance bond for 100% of project at contract signature which would happen

after Portage County Board Meeting on May 16, 2023. As indicated in the additional specification

above we would expect Contract Signature, Performance Bond, and Payment Bond be completed

within 10 days of the approval at the County Board Meeting.

Q2. We are looking at the above project. Can you please tell me what percent is needed for the Bid Bond?

And do you have required forms, or can we use the Standard AIA bid forms?

A. See Revision and Response to Q1. A Standard AIA form will work.

Q3. I have reviewed your project out for bid and I wanted to ask about the specification for the water

main directional drill. The main water main on this project is open cut 16” DR18 PVC pipe that provides

an internal diameter of 15.35” and a pressure rating of 235 psi. The directional drill, however, has 16”

DR11 HDPE that provides only 14.05” ID and 160-200 psi rating depending on safety factor. Due to the

thicker wall, HDPE pipe is typically upsized to prevent a reduction in capacity. DR9 HDPE would

provide a similar pressure class so that the HDD installation does not have a lower pressure class than the

open cut pipe.

I propose that the directional drill be completed with Fusible PVC pipe that would provide the exact same

AWWA C900 dimensions and pressure ratings. Fusible PVC pipe is a proven (over 19,000,000 LF

installed), fully retrained, leak free pipe system that is ideal for the rigors of trenchless construction

without the risk for chlorine induced oxidation. Stevens Point was one of the early users of Fusible PVC

pipe with 1,400 LF of 16” Fusible PVC pipe installed in 2004.

I have attached our general product brochure and a comparison of 16” DR18 Fusible PVC pipe and

equivalent HDPE pipe for your review.

• 16” DR18 DIPS FPVC pipe provides 15.35” ID and 235 psi pressure rating with 2.0 safety factor

• 20” DR9 IPS HDPE provides similar 15.29” ID and 200-255 psi rating with 2.0-1.6 safety factor

When would be a good time for us to discuss your project and this request?

A. The bid needs to be based on the specifications provided in the bid documents. Portage County does

not meet separately with bidders during the bidding process and all questions submitted by the

deadline will be answered by an addendum so that all bidders are provided the same information.
