Subject: 20" Force Main Isolation Valve Type: Bid Sheet
Question Date: 1/18/2022 12:05:23 PM
The existing isolation valve on the 20" Force Main where the Main comes out of the ground at station 15+00 appears to be in inoperable condition. Could a bid item be added to include one 20" Force Main hot tap of a new isolation valve?  
Answer   Date: 1/20/2022 6:34:59 PM
"HRSD Pipeline Sta. 15+00 is on the south end of this project closer to Commander Shepard Boulevard. It believed the valve in question is located at HRSD Pipeline Sta. 44+25 +/- (Roadway station 46+50) (Drawing sheet 26(8)). If that is the case, then this refers to valve 4 on HRSD valve guide YR3006 (See attached). In providing assistance to answering this question, HRSD Operations has stated/ asked the following: How do they know that the valve is inoperable? HRSD have not opened any of the valves at YR3006 during recent PMs because they are ‘split point’ valves. These valves are all plug valves installed in 2008. Valves #4 and #5 were last operated as part of the Semple Farm failure and repair in 2018/2019. Our records indicate that there were no issues with the operation of the valves.” Please clarify.

Subject: Asphalt Type: Plan
Question Date: 1/14/2022 2:29:37 PM
Please clarify asphalt sidewalk. Plans show existing asphalt road to remain in a sidewalk configuration, but are shaded as if the sidewalk is being milled and overlaid. In addition, the typical sections show a full pavement section with new base for this asphalt sidewalk.  
Answer   Date: 1/20/2022 6:41:11 PM
8’ of the existing asphalt road through the causeway will remain in place and be overlain as referenced on plan sheets 8, 9, 10. The remainder of the existing asphalt pavement outside of the shown 8’ width will be demolished, removed, and backfilled.  
 
Subject: Temporary Shoring Type: Plan
Question Date: 1/14/2022 10:32:34 AM
8. There is Temporary shoring shown on the substructure layout plan that is not shown on any subsequent individual bridge element plans with the exception of the PZ27 sheet pile shown on sheet 9. Specifically Abutment A, Pier 1, Pier 17, Pier 18. Are these additional temporary shoring locations required or recommended?  
Answer   Date: 1/20/2022 6:41:53 PM
Shoring is intended to facilitate construction around existing structure/roadway embankment/fill.  
 
Question Date: 1/14/2022 10:33:14 AM
10. The battered piles at Piers 17 and 18 appear to be in conflict with the temporary shoring. Do you have any details you can provide how you intended to install the temporary shoring at these piers to avoid the conflicts?  
Answer   Date: 1/20/2022 6:42:31 PM
If temporary shoring is installed 5’ from pile, at a batter of 2:12, that would allow 25’-30’ of depth below ground. The excavation at these locations is expected to be approximately 5’ deep, so 25’-30’ depth should be adequate. If additional clearance is needed, Contractor may utilize other means and methods such as leaving a gap in the sheet pile and/or providing additional bracing as needed.  
 
Question Date: 1/14/2022 10:32:55 AM
9. Are these additional locations to be incidental to item 2990 NS Bridge Temporary Shoring or a different pay item?  
Answer   Date: 1/20/2022 6:42:56 PM
Additional locations are to be incidental to NS Bridge Temporary Shoring.  
 
Subject: A3 Misc Concrete Type: Plan
Question Date: 1/14/2022 8:40:25 AM
Please clarify the quantity - the incidental summary shows a total of 4.148 CY but the bid form has a quantity of 9.52 CY. Also, please identify the A3 on Plan Sheet 17 as there is no callout  
Answer   Date: 1/20/2022 6:43:23 PM
The A3 shown on summary sheet 2R for Sheet 17 is an error. The quantity should be the combination of 1.333 on Sheet 13 plus the quantity of 5.456 on drainage summary 2j(5) for a total of 6.789 CY. The summary sheet 2R and bid form will be updated.  
 
Subject: Telephone System Type: Plan
Question Date: 1/14/2022 8:31:54 AM
7. Please confirm that Plan Sheet No. 55 which shows an 8 way telephone conduit system is shown only to represent the VDOT standard duct support and conduit details and materials and that the actual telephone conduit system to be installed on this project is a 2 way telephone conduit system as shown on Plan sheet No. 22 and not an 8 way conduit system.  
Answer   Date: 1/20/2022 6:44:13 PM
2-way conduit system is all that is required. The 8 way on sheet 55 is just a standard layout, but again, only a 2 way is required.  
 
Subject: Piles Type: Plan
Question Date: 1/14/2022 8:31:07 AM
6. Some timber suppliers have had difficulty providing the 12x12x50 timber piles as they are too long. Would the owner consider using a Class B or even 14" Class A Butt Pile? Or could the piles be spliced?  
Answer   Date: 1/20/2022 6:45:53 PM
12” diameter requirement is for butt end only; tip diameter shall be 9” minimum. This should be a commonly available pile. See also response to previous pile size question. No splice is allowed for the piles.  
 
Subject: CG-9D driveway Type: Plan
Question Date: 1/13/2022 10:04:05 AM
please double check the quantity for CG-9D (takeoff is 659 SY - bid qty is 285 SY) Pay items list 65 SY of 7" concrete entrance pavement and the legend on each sheet designated each entrance as a CG-9D.
