Questions/Clarifications

Questions / Clarifications

The following questions and issues were submitted to EFLHD at eflhd.conracts@dot.gov. The Government response or clarification is provided. Due to the repetitive nature of several questions and issues, the wording of the questions may have been revised and some questions have not been included. The Government’s direct response to the sender may also have been updated below for better clarity.

1. Under what item will the ultra-high performance concrete be paid?

Response: As specified in Subsection 552.03(v) of the Special Contract Requirements (SCRs) and on Plan Sheet R01, the ultra-high performance concrete is required for all closure pours and haunches for the Little Swan Bridge. Closure pours are only required for the Class D(AE) concrete and will therefore only be measured under the Section 552 Class D(AE) concrete pay item as specified in Subsection 575.21.

2. Section 104.05 defines load restrictions on National Park Service Roads. Precast substructure units and precast girders will exceed these weights. Will these restrictions on the Natchez Trace Parkway be waived for delivery of material to the project site from U.S. 412? If not, how does the Department propose these materials be delivered?

Response: The Subsection 104.05 load restrictions will not apply to the Little Swan Creek Bridge precast concrete units. The SCRs will be updated to clarify.

3. The bid items and specs call for Superpave Asphalt Mix. Superpave is not available or used in the state of Tennessee. Can the Asphalt be changed to TDOT STD (Marshall Mix Design) Asphalt?

Response: The SCRs for Section 401 Superpave Asphalt will be revised to allow a State DOT approved asphalt mix to be submitted for approval.
