Site 80 Volunteer Site

Site 82 Volunteer Site

Site 83 Volunteer Site

Site 84 Host Site

Note: Option Bid Item #1, if exercised, includes 2 – 2000 gallon precast concrete sewer vaults as detailed on plan drawings sheet M5.0 to be installed at the following sites as referenced on plan drawings sheet C8.0.

Site 56 Host Site

5) Please clarify the sales and excise taxes for this project (applicable percentages / applied to what amounts etc).

South Dakota excise tax imposed on the gross receipts for construction projects is at a rate of 2% and Pennington County does not levy a countywide sales tax. Please refer to the South Dakota Department of Revenue for more details.

6) Does Construction Industry have all the latest information and documents for this project?

The latest, most accurate information is contained within the solicitation.

7) I asked earlier about the electronic design files and Amendment 1 said they will be provided for construction. I wasn’t clear that I was looking for them now for bid preparation. Is that possible?

The www.Sam.gov website does not support the upload of DWG type files (i.e.

AutoCAD file types). Should contractors want these files, they must send an email to

Janice King at janice.king@usda.gov. Requests should be made prior to the quote due date.

8) Geotechnical Report / Groundwater Conditions - Please provide the geotechnical report, if available, including subsurface exploration data, groundwater elevations, and pavement design criteria. The specifications reference dewatering procedures; however, no groundwater information or anticipated subsurface conditions were identified in the bid documents. In the absence of a geotechnical report or defined groundwater elevations, contractor will have to assume groundwater is not anticipated within typical excavation depths. Confirmation is requested.

A geotechnical investigation was not completed. Groundwater is not anticipated with typical excavation depths.

9) Pavement Section – Bid Option Areas - Please confirm the required pavement structural section for all bid option areas, including: ◦ Aggregate base thickness ◦ Asphalt thickness ◦ Compaction requirements (percent of maximum density and test method) ◦

Required testing frequency.

Aggregate Base – See plan drawings sheet 12 of 52, C4.0

- See Specifications Section 321123, Part 3, 3.3

Asphalt – See Specifications Section 010250, Part 3, 3.3.B Option Item No. 2 – Asphalt

Surfacing. See Amended Specifications Section 321217, Part 3, 3.4

10) Existing Well Capacity and Condition - Please provide existing well logs, pump test data, historical production records, and confirmation that the existing well capacity is adequate to serve the expanded Loop B demand (36 sites). If capacity is found to be insufficient during construction, please confirm that corrective measures (including well upgrades or replacement) will be treated as a change to the contract. Contractor cannot assume performance of an existing system without documented verification.

See Attachment 16: Well Log. Improvements to Loop B will result in a maximum increase of 3 hydrants to the existing 15 hydrant system.

11) Water System Disinfection, Testing, and Sampling Requirements - Please confirm the specific disinfection standards (AWWA reference), sampling protocol, laboratory requirements, number of required passing samples, and testing agency requirements.

• Required removal depth below aggregate, pavement, and structural areas:

See Specifications Section 311100, Part 3, 3.2.A

• Whether full root ball extraction is required:

Full root ball extraction is not required. See Specifications Section 311100, Part 3, 3.2.A

See Specifications Section 312250, Part 3, 3.15

13) Rock Excavation – Definition and Payment - Please provide the contractual definition of rock excavation, including criteria for classification (rippable vs. non-rippable, size threshold, blasting requirements, etc.). Please clarify the method of measurement and payment if rock is encountered during trenching, roadway widening, or site grading. In the absence of a defined pay item, contractors will have to assume rock excavation is not anticipated within typical excavation depths.

See Specifications Section 312250, Part 1, 1.2.D.

See Specifications Section 312317, Part 1, 1.6.E

Rock is not anticipated with this contract. Only shallow excavations are required.

14) Designed Quantity Variations (<15%) - Please confirm the procedure for adjustment if actual field quantities vary from Designed Quantities by less than 15 percent, including whether unit prices will apply to overruns or underruns.

See Specifications Section 010250, Part 2, 2.1.C.1

For increases or decreases in quantity less than 15 percent, no adjustment will be made.

Design quantities will be paid.

15) Electrical Utility Provider and Upgrade Costs - Please identify the serving electrical utility provider and confirm whether any service upgrades, transformer upgrades, meter modifications, or coordination costs are included in this contract or will be provided by the Owner.
