1. Contract states installment payments will be made. Is there a time dictated to that?

Example: monthly billing while the job is going on?

a. No, each Contract Line-Item Number (CLIN) can be invoiced after completion.

See Section 1.6 Payment in the PWS. Payments shall be made in arrears.

2. Will one contractor be selected for all 4 sites?

a. Yes, one contractor will be selected for this contract.

3. Mariposa dam site: the work area highlighted is full of trees. To remove sediment from the noted area will require all the trees to be removed in that area. Or will we need to work around them?

a. Live trees are not in the Performance Work Statement (PWS) for removal. Live trees will remain in place, so you will need to work around them.

4. Contract states estimated cubic yards of sediment to be removed on all four sites and that sediment should be removed to native soil levels. What if to get to native soil it requires more material to be removed? Or do we just remove estimated number of materials?

a. See section 2.1.3 of the PWS, Clear the sediment deposits by removing sediment to the native earth. These are our best estimates, the intention is to have all sediment removed.

5. Owens and Mariposa Dam the estimated materials to be removed seems quite low for the area outlined in the contract.

a. These are our best estimates. See attached photos for examples E.2 though E.9.

The photos are representation of the debris and sediment removal required but debris removal is not limited to the views in the photos.

9. If the area remains dry can the date of work to be done change? Example scope states late May to October, if area remains dry can we work into November?

a. No. The short duration of the site work is due to accommodate the heavy equipment and the environmental concerns. All field work must be conducted between late-May and mid-October, prior to the first winter rain. Work activities will occur on days receiving less than .08 inches per 24- hour period, with less than a 40 percent chance of rain fall.

10. Bear Dam site notes a sediment depositing location, only sediment from Bear Dam can be deposited there? Or can materials from other sites be deposited there as well?

a. Note the Bear sediment deposit is no longer available as a deposit site. See revised Attachments and maps.

a. Correct, placement sites are not restricted by where the sediment came from.

13. Date of the start of work? 2025-2026?

a. Work can start as soon as the contractor submits the required documents and all the other conditions are meet. Section Period of Performance: The period of performance shall be completed within 730 days of contract award. The work at all locations must be completed to avoid the possibility of failure of a dam which would cause flooding. Section 1.3.1 of the PWS states “All field work must be conducted between late-May and mid-October, prior to the first winter rain. Work activities will occur on days receiving less than .08 inches per 24-hour period, with less than a 40 percent chance of rain fall.”

14. The project has a 2-year timeframe. Should we assume we are moving debris and sediment twice, once at each site, per season?

a. No that is not an accurate assumption. A 2 year POP is given as the available time to conduct work may not be long enough to hit all sites within 1 year, so a second year is given to complete all 4 sites, 1 time.

15. Do you have GPS coordinates of the Sediment Removal areas?

a. No

16. Do you know the weight capacity of the bridge on Owens Dam Rd?

a. There isn’t a bridge on Owens Dam Rd, but trucks weighing 20 Tons have crossed previously with no issues.

17. The PWS states Quantity of Sediment per site. Who is going to confirm the amounts off-hauled?

a. The government does not intent to check or confirm off-hauled amounts. The desire is to have all sediment and debris removed. That is the desired end state that the COR will be checking.

18. What happens if the sediment amount is larger than stated in the PWS? Will there be a Modification to increase the contractors pricing?

a. No. This is a firm fixed price contract. The contractors should make the best estimate of debris to be removed and properly disposed of to base their price offer.

19. Can the wood debris be burned or chipped at the holding yards provided? If so, does this debris stay at this site and get covered with the Wildflower hydroseed mix per the PWS?

a. No. All debris shall be properly disposed of off-site.
