Given the remote location and the volume of rock required for the job as well as the specification requirements, material sources need to be tested prior to bid in order to determine if they are an acceptable source. These test take time to obtain results. Additionally, there are several questions that have not been answered.

Please extend the bid date to allow for evaluation of answers when they are released as well as time to obtain test results on available sources.

9337177 Survey Section 31 09 13.00 29 Item 1.6

Comment Classification: Controlled Unclassified Information (CUI)

Item 1.6 states that at least one member of the field survey crew conducting the control survey and subsequent hydrographic and topographic field work must document at least three years of experience in surveying civil works projects (e.g. dams, levees, embankments, erosion control features, etc.) similar to this contract.

Is the three year requirement an absolute? Given the lack of long term projects of this type in Alaska, it may be diffcult to find anyone with those specific qualifications.

And secondly, are ther other types of experience that could be substituted (ie Construction, Control network surveys, Quantity Surveys, et cetera)?

Thanks.

(Attachment: Tanana_Sill_Groin_Repair_IFB-p176.pdf) On: Jul 22 2021.

Government Response. . Three years of survey experience on civil works projects is required however the qualifications can be met by other types of surveys such as construction surveys and quantity surveys.

9341572 Civil 35 31 19-2.2.1.1

Comment Classification: Controlled Unclassified Information (CUI) we are having difficulty finding rock within a reasonable distance to the project. Either the SSD specific gravity is too low (2.61), or the abrasion is too high (26). the only requirement for Alaska DOT Class IV rip rap is the abrasion shall be less than 50. Can the specifications for this project be modified accordingly to accommodate local materials?

On: Jul 26 2021.

9341840 Civil 353119-2.4.1

Comment Classification: Controlled Unclassified Information (CUI)

I asked this question 7-19-21 Assuming my riprap test results meet the specifications for this project, will the following gradation be acceptable?

50% weighing 2000 pounds or more 15% weighing up to 400 pounds 35% weighing 400 up to 2000 pounds

All angular well-graded stone.

And you responded that my gradation as written was ambiguous. Well I get that, but so is your riprap gradation Section 35 31 19 Part 2, 2.4.1. Furthermore in Part 3 3.2 Placement For Groin Repairs states

"Rock will be placed to the full thickness shown on the drawings. Rocswill be placed in such a manner as to produce a well-keyed mass of rock with individual pieces tightly in contact with each surrounding stone, and with the least practicable amount of void spaces. The finished surface must be free from pockets of single size rock.

Placement of small rock to chink the spaces between large rock, or for leveling the surface, will not be permitted".

Page 4 of 8ProjNet: Logged In User

I think it would be impossible to place all 2000 lbs stone or larger into a WELL-KEYED mass of rock without using a variety of well graded stone sizes up to 400 lbs. And a variety of well grades stone sizes over 400 lbs up to 2000 lbs.

Please help us understand what you are thinking would be an acceptable gradation for riverine erosion protection?
