About this file
This document is Addendum Number 2 to an Invitation to Bid (ITB) issued by the Oregon Military Department (OMD) for the Camp Rilea Armed Forces Training Center, specifically for installing groundwater monitoring wells at their Rapid Infiltration Basins (RIB) site. The addendum addresses two key requests for information from potential bidders: first, a discussion about piezometer diameter specifications, with OMD allowing potential post-award consideration of a 2-inch diameter instead of the originally specified 1-inch diameter; and second, an adjustment to the planned well depth for PZ-1, extending it from 55 feet to 60 feet below ground surface to ensure more consistent groundwater availability.
The addendum requires bidders to acknowledge the changes by submitting the modifications in their Exhibit 1 Bidder Submission Form, with any protests to the changes needing to be submitted via email to Corey.Brech@OMD.Oregon.gov by 2:00 P.M. on August 14, 2025. The contractor will be responsible for installing wells with final depths ranging from approximately 20 feet to a maximum of 60 feet below ground surface, depending on site-specific conditions, and must perform well development on each newly installed monitoring well to ensure accurate sampling and monitoring performance.

August 7, 2025
SUBJECT: Addendum Number 2 to ITB 250040C001 – Camp Rilea Rapid Infiltration Basins (RIB) Groundwater Monitoring Wells
TO ALL PROSPECTIVE BIDDERS AND ALL OTHERS CONCERNED
1. The changes, clarifications, omissions, additions, and alterations in, on, and to the bidding information and specifications shall apply to the quotes made for and to the project indicated above. Except as modified by this Addendum Number 2, all the terms and provisions of the Invitation to Bid (ITB) for the above listed project remain in full force and effect. This Addendum Number 2 supersedes all previous instructions pertaining to the items listed:
CHANGES TO ITB
2. Changes to ITB: The following revisions are made to the ITB. Where applicable, additions are indicated in bold and underlined and deletions are indicated by strikethrough.
A. Responses to Requests for Information. The following information is provided in response to a Request for Information (RFI) received regarding the scope and piezometer specifications in the ITB:
Question 1:
The ITB specifies a 1-inch diameter piezometer. Based on conversations with several drillers, a 2-inch diameter is recommended for ease of installation, development, and long-term stability. Would the Oregon Military Department (OMD) consider allowing a 2-inch piezometer instead?
Response 1:
The specified 1-inch piezometer remains the basis for bidding and evaluation. However, OMD is aware of industry preference for 2-inch piezometers due to ease of development and sampling. The selected Contractor may propose a 2-inch alternative during the submittal or approval process post-award, subject to OMD review and acceptance. Any such change must not affect project cost or performance.
Question 2:
The ITB references groundwater expected at 55 feet below ground surface at PZ-1 and specifies the well be installed to that depth. Would OMD consider increasing the total depth to 60 feet to better ensure consistent groundwater presence?
Response 2:
Yes. The final depth for the PZ-1 piezometer shall be extended to 60 feet below ground surface to ensure more consistent groundwater availability.
B. Attachment A – Statement of Work (Beginning on Page 53) Revise the following paragraph in Section SW-1, Description of Work:
Addendum 1 ITB 250040C001 2
The Contractor shall install each well to the planned depth specified in the Plan, with final well depths anticipated to range from approximately 20 feet to a maximum of 55 60 feet below ground surface, depending on site-specific conditions. The Contractor shall perform well development on each newly installed monitoring well to ensure accurate sampling and monitoring performance.
3. This addendum must be acknowledged and submitted for this project. By acknowledging this addendum in Exhibit 1 Bidder Submission Form, the Offeror agrees they have read and understood the above mentioned changes and have incorporated those changes into their Offer.
PROTEST OF ANY CHANGES TO THE ITB MADE BY THIS ADDENDUM MUST BE SUBMITTED IN
