Inquiry #4: A - Plan Sheet 101 indicates rock stain in some of the rip rap sections. Typically there is pay item for "Rock Stain" for this work. Please clarify...

B - Plan Sheet 101 indicates concreted rip rap in some of the rip rap sections. Typically there is a "Concreted Rock Slope Protection" pay item for this work. Please clarify...

C - For locations where RCP is required for "Alternative Pipe Culvert" bid items, what D-loading is to be used? This is not specified.

D - Item 17 for REAPs is 110 Each while Item 18 for SW Sampling & Analysis Day is 200 Each. A REAP is required at 50%+ probability of rain 48 hours out from time of work whereas the SW sampling occurs only when there actually is a qualifying rain event. So, I believe the quantity for Item 18 is vastly overstated and my be more like 50 Each?.. Please verify.

E - Quantities shown on Drainage Quantity portion of plans do not indicate any "miscellaneous iron & steel" or "bar reinforcing steel" relating to the "Structural Concrete, Headwall". Is the iron/rebar for headwalls incidental to the headwalls?

F - Item 44 pertains to temporary high visibility fencing. Is there removal needed? If yes, is the removal of this temporary fencing paid through Item 143 "Remove Fence"?

G - The Contour Grading Plans are not much of plans. They only provide contours for the fill at the bridge abutments. There is around a quarter million cubic yards of material that, according the roadway excavation quantities on sheet 227 (Q-2), appears to be attempted to balance on the project. However, a simple chart like this does not provide near the amount of data needed to more specifically calculate and estimate the earthwork. Are there more contour grading plans available depicting the 266,859 CY of roadway excavation and the 263,162 CY of embankment or CAD files or Cross Sections?

H - There are four PCMS that appear in the stage 1 traffic handling plans. They somewhat appear on the subsequent stages but in fainter graphic detail. Do the four PCMS remain throughout the lifetime of the project?

Working days for time-related overhead are shown as a lump sum value because the Department can't predict your overhead costs associated with your bid.

The bid book is a separate calculation. Because this is a cost-plus-time bid, there are two components to the bid:

1. Sum of the item totals
2. Total bid for time. For this portion of the bid, there is a fixed value for the cost per day of $19,200

Inquiry #18: The California Water Boards Permit and the Department of Fish and Wildlife Permit provided in the project informational handout both state that the project is to be constructed June 1 through October 31. What work can take place outside this June 1 – Oct 31 work window?

Specifically, can any of the following work take place outside the June 1 to Oct 31 work window:
i. Construction of Bridge Superstructure
ii. Roadway Excavation / Embankment Fill
iii. Tree Removal (during pre-bid it was mentioned tree removal can take place between Oct & January)

Response posted 08/23/2019


Response #2:
Your attention is directed to Condition 2.1 and Table 2 of the 1600 permit. The work window is June 15 - October 31, NOT June 1 - October 31, as shown in your inquiry, and is specifically for those project activities covered under the 1600 permit. In addition, the work window is only applicable to the 14 locations shown in Table 2.

If tree removal is scheduled during the nesting season of protected raptors and migratory birds (typically February 1 to September 30), a focused survey for active nests of such birds must be conducted by a qualified biologist within 15 days prior to tree removal. However, if tree removal is done outside of the nesting season (October 1 to January 31), then no nesting bird surveys are needed prior to tree removal. Please see Condition 2.14 of the 1600 permit.

Inquiry #27: The cut fill slopes shown on Layout Plans L-2 and L-3 do not account for construction equipment, access roads and falsework pads required to construct the bridge. The bridge will require extensive clearing, grubbing and earthwork outside the ESA to construct the bridge. Answer to question 11 does not permit clearing, grubbing, earthwork or grading outside the cut fill lines shown on the layout sheets. The area below the bridge is outside the cut fill lines that are shown on the layout sheets. Standard specification section 17-2 does not address clearing and grubbing forest areas within the right away. Bridge construction will require approximately 100’ beyond the edge of bridge deck of clearing, grubbing, tree removal, earthwork, rockwall, temporary erosion control and permeant erosion control work not shown on the plans.
1. Is additional clearing, grubbing and tree removal allowed for access roads, equipment pads and falsework pads required to construct the bridge? If so, what bid item includes payment for this work?
2. The majority of trees within this area require removal. Can all trees outside the ESA and within the right of way be removed as necessary to accommodate access? If so, what bid item includes payment for this work?
3. There will be extensive earthwork and grading to accommodate bridge construction. Is the contractor permitted to widen the existing access road from highway 20 near D line station 40+99 to allow for equipment and material deliveries and to provide 20’ fire break on both sides of the access road? If so, what bid item includes payment for this work?
4. Based on all access roads, clearing, earthwork and grading described above; are the access roads, equipment pads and material pads permitted to remain in between construction seasons with appropriate BMP’s in place? If so, what bid item includes payment for this work?
5. Based on all access roads, clearing, earthwork and pads described above; will the existing rockwalls and slopes require protection in place or reconstruction to match existing prior to project completion? If so, what bid item includes payment for this work?

Inquiry #29: The response to inquiry #24 does not answer the question asked. The Foundation Report and the Special Provisions clearly states that if an oscillator or rotator is used, you can't drill out the casing until you reach the specified tip elevation. Although the rock shown is of differing quality, the entire length of the 90" CIDH is deemed a "rock socket". There are portions of the CIDH piling that would not require the use of casing (REC 100%, RQD 100%, UC 20,753 psi), however, the Special Provisions indicate that if an oscillator or rotator (casing) is used it must be taken to the specified tip elevation prior to removing the bottom 10' plug. Contrary to the response provided to Inquiry #24, this Special Provision (Section 49-1.01A 7.2 ) gives very little leeway to the contractor as to how to build the CIDH pile (in regards to the use of temporary casing) as currently written. Was the intent of the Special Provisions Section 49-1.01A 7.2 to require full-depth casing (through rock of all quality) if used?

Inquiry #35: Sheet 274 of 284: The Elevation View indicates a No-Splice Zone Starting 18' from the bottom soffit and extending down 45'. Column heights above existing grade vary from 44' to 65'. The Specifications indicate that temporary casing may be required. This No-Splice Zone puts all the risk on the Rebar and Drilling Subcontractors to deal with either coupling a rebar cage below grade (up to 20' below grade) or having to lift casing and equipment up and over a column that extends 44' to 65' above grade. Currently one of the splices lands above the existing grade. Can the No-Splice zone be adjusted to allow for a splice at or near grade for the safety of all involved?

Inquiry #37: Sheet 274 of 284: Elevation View. A No-Splice Zone is indicated starting 18' below the bottom soffit and extending down 45'. The column cage portion of the reinforcing cage extends 44' to 65' above the existing grade. Based on the No-Splice Zone indicated, there are places where the allowed splice will be above the existing grade and other places where the splice is 3' to 19' below grade. There is no consistency. Casing may be required to support the shaft during construction. The rebar subcontractor and the drilling subcontractor is taking on the safety risk to either have to couple the rebar cage in a cased hole or have to support a 44' to 65' column cage while casing and possibly an oscillator is lifted up and over. Having to support the column cage and rig and un-rig the column cage is high risk work. Can the allowable splice zone be consistent at all the CIDH piles and be at or near the existing ground surface?

Inquiry #38: Since the project bid date has been postponed for approximately 2-weeks, please reconsider the response to inquiries #35 and 37 regarding the No-Splice zone for the 90" Dia. CIDH piles/ 84" column extensions. The No-splice zone indicated does not take into consideration the height of the column extension and there is no consistency as to where the splice currently lands. Casing will be required to allow for a splice below grade. That casing length varies from pile to pile based on the use of the dimensions provided.

Inquiry #39: In regards to Bid Item 143 (Remove Fence) there appears to be an existing Livestock style gate on the fence line that is to be removed. The gate appears to be located with in the fence line that is shown to be removed on plan sheet L-2, near 72.88' L+ "D" 28+80.96. My question would be, is this gate to be removed along with the fence? and will the removal of this gate, or any other gates that may be on the fence line to be removed, be payed for under the same bid item #143 (Remove Fence)?

Inquiry #40: In regards to bid item 161(F) - Cable Railing, project plan sheet DP-20 (72 of 284) calls out cable railing to be installed at Drainage System #20. There is a note to install 9' of cable railing, but this quantity is not mentioned on the summary of quantities sheet Q-3? Plan sheet D-5 does not appear to call out any type of cable railing at Drainage #20 either. If we include these 9 linear feet, this would bump up the overall footage for bid item #161(F) to 134 linear feet, please advice if drainage #20 will require cable railing, and/or if the quantity for this bid item will change?
