ITB #S-63500-00014312 Questions & Answers

1. The current gangway and dock design appears to include proprietary parts and Design from a specific manufacturer. Could these specifications be altered to avoid any potential legal issues?

a. After checking into this we can not find anything that would suggest what is stated. The gangway was designed in house and the dock is a modified version of a dock the marine board had. We have a working relationship with the Marine Board and share designs with each other as needed. It would be nice to see a stamped set of plans for this design you are suggesting to compare because the last thing I want is to have anyone thinking we are using their design without permission.

2. Also, I wanted to note that the use of angle mid-rails can pose a safety hazard due to un-closable ends and edges. This is no longer an industry standard. Schedule 40 pipe with end caps is now commonly used to prevent finger injuries, especially for children.

a. As of right now we will not be making any changes to the design on either unit. These are the approved set of plans for this project and to make a nonstructural or safety compromising change that is not necessary would put too much of a delay on the project. Thank you for the suggestion and it will be noted for future designs and projects.

3. Is this Project Contractor Design Build? Can contractors use their own Design for Dock and Gangway in regard to member sizes and Howe Truss?

a. No, this was signed off by ODFW engineering and is the system that is required for this project.

4. Can Molded Fiberglass Decking Be used as a Substitute?

a. No, the decking that is called out is the type that the Oregon Marine Board requires for ADA access.

5. Is the Gangway the sole anchoring device for the dock?

a. Yes

6. Can Vertical Pickets be used on the Dock Guardrail?

a. No, the handrail was designed specifically for ADA and wheelchair access fishing.

7. Is the Gangway required to meet AASHTO Pedestrian Bridge specifications?

a. No

8. Can Soda blasting be Excluded as it can cause Premature degradation of the material shortening the life span.

a. No

9. Can you Provide loading Requirements for dock and gangway?

a. No, this information is not needed since the system has been approved by ODFW Engineering, and the contractor is not allowed to alter the design when fabricating.

10. For you to provide materials is a very odd way of doing a project like this. I think you're going to have a hard time with that as it's not very laid out as how that would happen. Would you provide al the takeoffs for material and have them freighted to the shop? Would material be long lengths or cut to dimensions?

a. We have provided material on a job like this before, and it is harder than just having the contractor provided the material but saves us money in the long run. With buying large quantities of material from certain suppliers we can usually get better deals, and this will end up letting ODFW stay with in budget. A material inventory can be provided to the contractor if requested after the contract is awarded, but a cultist will be the responsibility of the fabricator. All metal will be supplied in raw form with the sicks in lengths between 20 and 25 foot and all sheets in 4ft by 8ft size. Delivery of the material will be determined after contract has been awarded and location of the contractor’s shop is known.
