Linwood Ave - Addendum No 2 UPDATED.pdf

Linwood Avenue Improvements Addendum No. 2 January 12, 2023

Questions/Answers and Clarifications:

1) Referring to the Good Faith Effort (GFE) form in the Instructions to Bidder, can you provide the Divisions of Work that GFE (unless self-performed) is required for?

Answer: Please complete the GFE forms as stated in the Bid Package. Clackamas does not provide NIGP or NAICS codes.

2) Would the PM consider adding a bid item for Flagging (paid by the hour)?

Answer: Flagging costs will be kept as incidental to BI 4 “Temporary Work Zone Traffic Control, Complete”

3) Please clarify the layout/details of fencing/railing beyond each corner of the pedestrian bridge.

Answer: Bridge railing will terminate at limits of the bridge. Chain link fencing will be added at all four corners as shown on revised drawing 5.7C

4) Sheet 12.5 of the traffic signal plans indicates 2 FLIR TrafiSense2 detection sensors.

Can you confirm quantity? Is the intent to detect bikes as they approach the signal or only at the signal, stopping / waiting area?

Answer: Yes, we need 2 FLIR detection sensors there, and they are for the bikes on the Springwater trail.

5) On the Traffic Signal Plan, it calls for a blank out sign. I don’t see specification or detail about this sign other than what is listed on Sheet 12.8. Are there more details?

Answer: The PTR sign are in the blue sheets. The pre-approved manufacturers are McCain and Wells Manufacturing.

6) In the Special Provisions (01120.0) it states “this work consists of the design-build irrigation system at Mill Park.” Does this refer to only areas affected by construction or a complete park system?

Answer: This statement refers to only areas affected by construction or where new mitigation plants are installed in middle area of the park. Sheet 9.2 indicates (by hatch) the area for inclusion of the temporary irrigation system. 01044.90 indicates that 2nd and 3rd year plant establishment at Mill Park includes all plants identified as “Mitigation Plantings” (BI’s 93-96).

7) The Special Provisions (01120.40) refer to schematic park irrigation drawings. Please provide as-builts of the existing system.

Answer: At this time, we do not have as-builts of the existing irrigation system at Mill Park. For bidding purposes, bidders can assume there is an existing irrigation system within the park and that they can connect to that existing system without making an independent connection to a public main. During construction, the Contractor will need to coordinate with Park staff to locate the existing irrigation system as part of their irrigation system design submittal.

8) Special Provision 01075.0 (Miscellaneous Private Property Adjustments” clearly identifies all fencing but makes no mention of existing irrigation systems on private property. If the fencing installation damages existing private irrigation, is that the responsibility of the fencing contractor to repair or not?

Answer: The prime contractor is ultimately responsible for all work on the project.

The County does not determine how individual tasks on the project are allocated to subcontractors. Section 01120.10 includes language to “repair to existing private irrigation systems damaged by construction improvements”. Fence installations required under 01075 are part of the construction improvements, and therefore the County would consider repair of private irrigation damage resulting from new fence construction to be covered under BI 134.

9) Special Provision 01044.21 states “water all newly installed plant materials…using the installed automatic irrigation system unless otherwise directed by the Engineer” Are meters and water connections designated for use on this project? Is temporary establishment irrigation the architect’s intention?

Answer: This project does not have an installed automatic irrigation system for the street trees and road landscaping. Therefore, watering for plant establishment under this section and BI 105 would be a continuation of the hand watering method required under 1040. BI 106 (Plant Establishment at Mill Park) would utilize the project-installed irrigation system for those plants. The automatic irrigation system for Mill Park will be connected to the Park’s existing irrigation system, therefore there will not be a need for separate contractor-provided water meters.

10) On drawings 5.0 through 5.7, Notes 53 and 54 identify meters, however it is unclear if those are private or public meters. Please advise if those meters are able to be used for right of way irrigation.

Answer: Notes 53 and 54 reference private property water meters that are being relocated for the project. They are not available for public irrigation.

Project Plans:

The following Plan Sheets have been updated:

Sheet Number(s) Description of Change

3.7 Updated Concrete Inlet Detail to reflect 18” min. sump

5.2 Revision to “Minor Adjustment” notes

5.4 Revision to “Minor Adjustment” notes

5.5 Revision to “Minor Adjustment” notes

5.6 Revision to “Minor Adjustment” notes

5.7 Revision to “Minor Adjustment” notes

5.7C Clarified Rail/Fence conditions at Pedestrian Bridge

5.8 Revision to “Minor Adjustment” notes

15.3 Added Lateral Extension

Add Modified Path Exhibit (SE Queen to SE La Jolla)

Note 1 - Detailed sheet revisions for the “Modified Path Exhibit (SE Queen to SE La Jolla)” will be provided with the IFC set. Approximate quantity adjustments for unit-based bid items have been captured in this Addendum or will be adjusted as required per field measure. It is assumed all bidders will make appropriate adjustments in their bid for LS items such as Mobilization, Traffic Control, Earthwork, etc. as required to incorporate this modified work.

Note 2 – The Project Drawings refer to some water meter/hydrant relocations or adjustments as work to be done “by others”, referencing City of Milwaukie. Clackamas County is working on an IGA with City of Milwaukie that would result in the inclusion of these tasks as Contractor work. This Addendum has added Bid Items associated with this City of Milwaukie water work, but if the IGA is not finalized, they could be removed from the project. If implemented, appropriate references in the plans of “by others”, and “For Informational Purposes” on Sheet 3.11, would not apply.

Special Provisions:

The following changes have been made to the Special Provisions:

00180.65 Right-of-Way and Access Delays – Modify the Subsection as follows:

There are possible Right-of-Way delays on this project. Although negotiations for Properties 9, 35, 69, and 70 are complete, they are still in the County payment process. We anticipate that this will be complete prior to NTP, however if it is not, work on these properties would need to wait until payment has been made.
