QUESTION #1

Is borrow material available on the project site?

Response: No

QUESTION #2

Will the Government make a pay item for borrow?

Response: No, borrow material is included in the cost of the embankment construction

QUESTION #3

Under Schedule A, can the Pay Item No. 40101‐0500 “Superpave Pavement, 1/2 –Inch…” be changed to a 404 “Minor Asphalt Concrete”? There is a few reasons for requesting this.

There is a requirement for the use of an MTV on this pay item. This might not be the best use of this equipment for low water crossings.

There is also a requirement for 3 rollers during this operation under the 401 section. This might be a little excessive for 100’ and 200’ intermittent stretches of HMA.

The pavement smoothness for this work is a Type IV. This will be hard to achieve give the length of each pavement section at the Low Water Crossings and also hard to measure per the specifications at the proper test speed.

This mix design process for 1,220 tons is fairly involved and using the Section 404 JMF is a little more forgiving and less expensive for these few tons.

If the pay item remains unchanged for this work in Schedule A, can exemptions be made for the smoothness, quantity of rollers, pavement smoothness, and the MTV?

Response: 40101 will not be changed. We are making a few minor changes to the smoothness/roughness specifications as well as roller requirements to account for the low water crossings. This will be amendment A001 or A002.

QUESTION #4

Section 204.05 states that the contractor is to conserve topsoil to the extent and depth as determined by the CO. Can the parameters for conserving topsoil be stated as this could be a large items or a very small item. In order to provide a competitive proposal, this quantity is extremely helpful to have.

Response: Amendment A001 or Amendment A002 will discuss topsoil. The parameters will be stated.

QUESTION #5

Section 253.05 discusses the use of granular backfill when Gabions are set on a “rocky foundation”. What would be considered a “rocky foundation”? Cobbles are present in the area of the structure but is this considered rocky?

Response:

Specifications will be corrected in Amendment A001 or A002 to remove the language in the SCR’s. This will mean that section 253, which then refers to section 209, will be the specification for gabion foundations.

QUESTION #6

I was wondering if there was going to be a Pre‐Bid meeting for the above referenced project?

Response: There will not be a coordinated site visit. The contractor is urged to visit the site prior to bidding.

QUESTION #7

Is it possible to obtain the digital design files for the Dripping Springs project in order to verify excavation and imported borrow material quantities? We would like to perform a digital quantity verification prior to bidding the project since the pay item is embankment and the borrow material will be a large factor in the embankment pay item pricing.

Response: Nothing will be provided besides the plans and specifications.
