Common use of Roadway Foundation Clause in Contracts

Roadway Foundation. All proposed unreinforced fill and cut slopes shall be 3:1 (H:V) or flatter except bridge end bent slopes (see Section A – Structure Foundations). In areas where a sliver fill is required to tie the proposed grade into the existing ground, fill slopes may be steeper than 3:1 (H:V) provided the existing slopes are stable and erosion control measures are utilized on the sliver fill slopes. However, in no case shall a slope be steeper than 1.5:1. The Design-Build Team shall submit slope stability analysis verifying stability of any modified slopes, including details to control erosion of the slope. For all other proposed slopes steeper than 3:1 (H:V), the slopes shall be reinforced and detailed design calculations shall be submitted to the NCDOT Geotechnical Engineering Unit, via the Design-Build Unit, for review and acceptance. Bridge approach fills shall be required for end xxxxx on all bridges in accordance with NCDOT Standard Drawings and NCDOT design criteria. Standard Drawing 422.11 of the NCDOT January 2012 Roadway Standard Drawings shall be used on all bridges.

Roadway Foundation. All proposed unreinforced fill and cut slopes shall be 3:1 2:1 (H:V) or flatter except bridge end bent slopes (see Section A – Structure Foundations). In areas where a sliver fill is required to tie the proposed grade into the existing ground, fill slopes may be steeper than 3:1 2:1 (H:V) provided the existing slopes are stable and erosion control measures are utilized on the sliver fill slopes. However, in no case shall a slope be steeper than 1.5:1. The Design-Design- Build Team shall submit slope stability analysis verifying stability of any modified slopes, including details to control erosion of the slope. For all other proposed slopes steeper than 3:1 2:1 (H:V), the slopes shall be reinforced and detailed design calculations shall be submitted to the NCDOT Geotechnical Engineering Unit, via the Design-Build Unit, for review and acceptance, prior to construction. Bridge approach fills shall be required for end xxxxx on all bridges in accordance with NCDOT Standard Drawings and NCDOT design criteria. Standard Drawing 422.11 422.02 of the NCDOT January 2012 2018 Roadway Standard Drawings shall be used on all bridges.
