WA FLAP LINCOL 57860 (1), & WA NPS LARO

208(1), Hawk Creek Road Improvements & Hawk Creek Road Stabilization

# General Technical Question Answer Date

1 X

I wanted to reach out and see if this was still going to drop during this winter or based on the shutdown if it is going to slide to the right a bit. I wanted to check and see if there was a new estimated drop date or time frame.

We are still anticipating that this project will be advertised this winter.

I am looking over the documents and I noticed there are two SWPPPs listed. I am wondering if they are both needed, as I believe they are identical except for a few pages. The "Hawk Creek Compiled SWPPP for contract" file has an extra blank page and a Tab 3 divider page on pages 64-65 (also has a higher page count by 2), while the "waa-lincol57860-1_SWPPP" file is missing the blank page and has the Tab 3 divider page in the correct order, but has signatures the previous report is missing on the NPDES on page

64. There are a few blank pages that may be put in a slightly different order from each other, but otherwise everything looks the same. There are a couple of divider pages that say there should be photos included also.

Please disregard "Hawk Creek Compiled SWPPP for contract" and use file name “waa-lincol57860-1_SWPPP”. This will corrected through an amendment.

Minimum soil nail lengths and maximum nail spacing according to wall section height for the contractor’s design are provided on sheet K.3 and some discussion related to minimum soil nail requirements are provided section 6.1 of the geotechnical report. Is it possible for Shannon & Wilson to provide the output results from the slope stability analysis that was completed for preparation of the geotechnical report? This would be helpful in bid preparation for the soil nail engineer to determine if the minimum nail lengths are adequate or if longer nail lengths are required when checking for internal stability and temporary stability.

This information will not be provided.

Prepare bids according to information provided.

The site is relatively remote without ready mix batch plants nearby. Will the CO allow for the shotcrete mix design and applicable additives to be specified and approved by the wall engineer of record in order to accommodate the increased time required for transport and application?

Submit proposed admixtures for approval with the shotcrete mix design according to Subsection 566.04. See Subsection 566.05 for requirements of hydration stabilizing admixtures.

In past experience with carved and stained architectural finishes for shotcrete, we have found that best and most durable finishes are achieved when a curing compound is not applied to the carved finished once carving is completed. Will the CO allow omitting the curing compound requirement for the architectural finish? Curing compound, as required by specification, would still be used on the temporary facing and structural facing.

Cure shotcrete according to Subsection

566.08. Curing methods must be

compatible with the proposed stain and included with the shotcrete mix design submittal according to Subsection 566.04(j).

Will the CO allow for proof test nails, provided they are successfully tested, to be incorporated into the work as production nails? Or are scarification proof test nails required?

Successfully tested proof tests can be incorporated as production anchors if they meet the requirements of Subsection

259.08. Perform proof testing on

production nails according to Subsection 259.09(b)(2). See Subsection 259.14 for acceptance criteria.
