Inquiry #5: The quantity for bid item 10 temp railing (type k) appears overstated. Please note the following two issues:
a) K-Rail along Line "D2" is shown to occur from STA 131+00 to STA 132+60 (160LF) on both sides of the ramp on plan sheet TH-6, however, the 'Traffic Handling Quantities' table on plan sheet THQ-1 lists the end stationing as 136+40 for both runs. This in turn has caused the LF to be listed incorrectly as 540 LF for both runs.
b) The 'Traffic Handling Quantities' table on plan sheet THQ-1 lists k-rail occurring from STA 124+00 to 129+40 along the "D2" Line on plans TH-5 and TH-6. Plan sheets TH-5 and TH-6 do not show any k-rail occurring on the "D2" Line at this stationing.
Will the Traffic Handling sheets be revised to reflect the stations shown on THQ-1? Or will the quantity for bid item 10 be revised to 13,000 LF?

Inquiry #6: In reference to the Water Distribution Systems ~
1)A supplier for the 10" and 14" conduit, spacers and end seals for the 6" and 8" water distribution systems noted that the conduit sizes (10" & 14" ) would need to be upsized to 12" and 16" [respectively] to accept the OD of the casing/conduit spacers shown on the plans.
1A) In addition, we have contacted directional drilling subs that will be quoting the 10" & 14" lines. If the 10"and 14" lines aren't feasible, the directional drillers will need to be noticed as soon as possible so the accurate conduit sizes as are considered in our quote

Inquiry #10: Is AWWA C-900 Fusible PVC (FPVC) pipe an acceptable alternative to the casing crossings, like previous CalTrans projects? The Dimension Ratio (DR) sizing can be matched to meet or exceed the Schedule sizing requirements. The fused joint gasket-less system has a comparably smaller outer diameter since there is no bell, and can meet the initial requirements of 6" PVC inside 10" PVC casing, and 8" PVC inside 14" PVC casing without needing the upsized conduit per Addenda #4.
Supportive documentation and existing CalTrans project list can be provided.
