Inquiry #7: In the special provisions section 12-3.20(3)(c) Indicates that the contractor is to install a minimum of 260 feet of temporary steel barrier, is this the intention of the state to have this utilized on this contract.
Inquiry submitted 06/22/2022
Response #1:Submitted for consideration.
Response posted 06/22/2022
Response #2:This spec basically means “if†12’-9†Temporary Steel Barrier is used then the minimum length is 260’. This is the minimum length required for that system to work. Just as how the 50’ temporary steel barrier minimum length is 250’ and the minimum length for Type K railing is 160’. So depending on the system they choose, those are the required minimum lengths.

Inquiry #8: Section 36-3.01D(3)(b)(i) of the Standard Specifications states that the contractor is to test pavement smoothness for an inertial profiler except use a 12-foot straightedge for the pavement at:
"1. Traffic lanes less than 1,000 feet in length, including ramps, turn lanes, and acceleration and deceleration lanes."
It appears that Ramp #2(line MA2), Ramp #3(MA3), Ramp #4 (MA5), Ramp #10(SB1), Ramp #12 (WS1), Ramp #14 (SB2), Ramp #18 (NW1), Ramp #23 (MA8), SB101 Off Ramp Connect to San Bruno Ave (NS1), San Bruno Ave (West San Bruno Ave SBA 1), and NB101 ON From Dubuque Ave (OP5) are all more than 1,000 LF.
Since they are over 1,000 LF is an inertial profiler required or is just a 12-foot straightedge required since these are ramps, acceleration and deceleration lanes.
If an inertial profiler is required to test smoothness, please provide the ProVal files for these ramps so that the existing smoothness can be determined.

It seems that these quantities have doubled up. The plans haven't changed but the total LF quantity for the 6" Broken 36-12 has increased by more than double the original quantity for the entire project.
This stands out on sheet PDQ-14. The SB "NE1" line from Sta. 1361+03.7 to Sta. 1375+96.5 has a total of 13,500 LF - 6" White (Broken 36-12).
According to the plans and the existing conditions there is only 4,500 LF.
