0

7.
Q: It appears that tax will be paid on the whole of Schedules B & C while no tax will be paid on Schedule A but would be required to be included in the various bid items. Our read of the requirements of the tax rules lead us to believe that because the State of Washington is the owner of the project property, the tax rule that applies to that conditions requires that tax be paid to the Contractor on the whole of the project. Based on the ownership of the land, it appears that 1-07.2(2) Tax Rule 170 applies, not 1-07.2(1) Rule 171 as stated in the proposal. Please clarify this.
June 11, 2019
A: See new document attached regarding correspondence from the Department of Revenue (DOR). Based on DOR correspondence, the City of Sumner does not expect to pay tax on Schedule A.
0

8.
Q: There is no provision for rail road flagging in the contract. We heard at the pre-bid meeting that no rail road flagging would be required and that bidders should not include any scope/cost in their bids for rail road flagging or rail road coordination. Please clarify.
June 11, 2019
A: No railroad flagging is expected to be required as part of the project.
0

9.
Q: The special provisions provide for single lane closures of SR-410 and Traffic Avenue during normal working hours. Please clarify what is meant by normal working hours. Further, these closures are for setting temporary barrier. Will single lane closures of Traffic Avenue and SR-410 be permitted for scopes of work requiring access and a closed lane and if so, during what hours?
June 11, 2019
A: See 1-08.0(2) of the project specifications for Hours of Work definition. No single lane closures are anticipated for scopes of work beyond barrier placement.
0

10.
Q: There is no noise ordinance contained in the bidding documents. Our assumption is that there are no restrictions for night work. Please clarify.
June 11, 2019
A: Per environmental documentation, project is exempt from City' noise control ordinance and is not required to be mitigated. The contractor should plan employ standard simple techniques to reduce noise impacts during night hours (turning off engines while not use, driving forward as much as possible to reduce back-up alarms, substituting hydraulic or electric tools for impact tools, etc)
0

11.
Q: There is 2 Bid Items with the same number (A-25). Will an addenda be issued to correct the bid schedule?
June 11, 2019

0

12.
Q: Reviewing the special provisions section 1-07.18 there is no provision for Railroad Protective Insurance. The work is, in places, less than 10 feet from the BNSF R/W. Past practice has indicated that a RR Protective policy should be applied. Please clarify.
June 11, 2019
A: No agreement exists with the railroad that requires railroad insurance.
0

13.
Q: There is no special provision for section 2-09 for Shoring or Extra Excavation Class A as it relates to the adjacent railroad R/W. In all cases where a railroad is adjacent to or within the work zone, conditions and limits are provided for shoring systems. Please provide this information.
June 11, 2019
A: Project has acquired no rights to work on BNSF property. Shoring and all project elements shall remain outside of BNSF property.
0

June 11, 2019
A: Item A-42 shall be paid per Section 6-19.5
0

15.
Q: Can a Tensar MESA Retaining Wall system be substituted for structural earth walls on the project? The request is chiefly about constructability (due to highly variable bottom of wall elevations) but also could reduce cost and improve schedule.
June 11, 2019
A: Substitution requests will be processed after bidding is complete. The issued project specifications have been reviewed and approved by WSDOT. Any modifications will need to be approved by both the City of Sumner and WSDOT.

0

18.
Q: The Superstructure quantities listed on page 277 of the specification book (Section 6-02.4) shows quantity 24 each Elastomeric Girder Stops. However, looking at the plans it appears there are girder stops on the outside beams which would make the quantity 28. Please confirm.
June 14, 2019
A: The quantity should be 28. This has been corrected in Addendum 1.
0

19.
Q: 1. The bid quantity of 434 CY for Bid Item A-45 is significantly greater than the takeoff quantity as calculated from the plans. Will the bid quantity for Item A-45 be updated to reflect the quantity based on concrete dimensions shown in the plans?
June 14, 2019
A: The quantities for "Conc. Class 4000 for Shaft Cap" and "St. Reinf. Bar for Shaft Cap" are meant to cover the abutment walls as well. Both bid items have been renamed in Addendum 1.

0

22.
Q: 4. Due to the proximity of the BNSF Railroad ROW and tracks, shouldn’t there be provisions for Railroad Protective Insurance, Railroad Flaggers, etc. since we will be using cranes and other equipment that could be able to foul the tracks while building the bridge and other structures? Likewise, boring under the BNSF railroad tracks usually requires that we provide Railroad Protective Insurance and have an agreement in place with the Railroad.
June 14, 2019
A: No railroad flagging is expected to be required as part of the project.  No agreement exists with the railroad that requires railroad insurance.  Project has been coordinated with BNSF and through WSDOT to come to these conclusions.
0

23.
Q: 5. Can you make the boxes in the Bid Schedule large enough to legibly hand write NUMBERS (digits) for both the Unit Prices and the Totals? There is barely enough room to hand write even 4 digits in the current form and if our bid runner needs to make a change in a price, it will be nearly impossible to read the numbers.
June 14, 2019
A: The Proposal form has been modified to provide more space. Only numbers need to be written, to 2 decimal places.
0

24.
Q: 6. Special Provision Section 5-04.5 states that “Water” per M gallon will be paid in accordance with Section 2-07.5. Standard Spec Section 2-07.5 calls for payment by Bid Item. Will you be including a bid item in the proposal for “Water”?
June 14, 2019
A: There will not be a bid item for "Water". The standard specifications state that "When the Contract does not include water as a pay item, providing and applying the water shall be incidental to construction. All costs shall be included in the other Contract pay items."

25.
Q: 7. Please provide either cross sections for each abutment from 100’ behind each abutment to the edge of SR410 OR provide the existing topography at each abutment. The topo’s shown on Plan Sheet BG1 do not show the existing grades well enough to determine shoring, structural exc and access requirements.
June 14, 2019
A: A plot of existing topography around the bridge abutments has been added to the documents section on SolicitBid.

Q: 1. Concerning Decorative Poles – 25-Foot Height: Will the city consider a fluted steel pole with bolt circle as per foundation design with cast aluminum decorative base cover clam-shell of design and scale consistent with listed approved? This request is in order to be compliant with FHWA domestic sourcing requirements of steel and cast iron. 2. Concerning Decorative Units – Teardrop Style: Will the city consider a more efficient lower wattage with higher output fixture of same shape and scale with Acrylic ribbed short teardrop globe?
June 14, 2019

June 14, 2019
A: We are unable to release CAD files for the project, but we have now included an exhibit of the existing topography in and around the bridge for completing takeoffs.

28.
Q: Due to the 12% UDBE Goal and the limited number of UDBE responses we have received confirming that they will quote, would you please extend the bid due date at least two weeks?
June 14, 2019
A: UPDATE: THE BID DATE HAS BEEN PUSHED BACK TO ACCOMMODATE ADDTIONAL REQUESTED TIME. SEE ADDENDUM #2.
0

29.
Q: Based on the response to Q&A # 9 “No single lane closures are anticipated for scopes of work beyond barrier placement.” We feel that several scopes of work will require at a minimum single lane closures on SR410. Some examples would include - installation of underbridge utilities and supports, overhang forming and stripping, pigmented sealer on overhang and barrier, installation of protective screening on existing barrier, removal of temporary barrier. Will single lane closures on SR410 be allowed for other items of work beyond barrier placement to protect both the traveling public and our workers?
June 14, 2019
A: No single lane closures other than for barrier setting have been specifically approved in advance by WSDOT. If additional single lane closures on SR 410 are requested by the contractor after bid, WSDOT and the City would have to approve the request. Based on previous coordination with WSDOT regarding lane closures, it would be reasonable to assume that single lane closures would only be allowed at night.

Q: Referencing question #28, we have also noted a severe lack of participation with UDBE potential participants and other specialty subs based on the advertising window and outlets. Many resondents had not heard about the job. We request that the city consider postponing the bid opening 2 weeks to allow more time to solicit specialty and UDBE subs.
June 17, 2019
A: The bid date has been pushed back to accommodate additional requested time. See addendum #2.

Q: Referring back to Q 20 response, please confirm. The "electrical conduits and supports for utilities" are clearly paid for under LS for Superstructure. This is under heading "Bridge Supported Utilities" and seems clear for the utility hanger conduits. Typically you will see barrier conduits paid for under the systems bid item. Sheet SG2 is where it calls out the (2) 2" spares and IL1 calls out (1) 2" for illumination, all in barrier. Please confirm that all materials starting with the expansion fittings, including barrier boxes, will be paid under Superstructure bid item.
June 26, 2019
