Section 201.03 of the contract documents states:

“Do not access any part of the construction access limits without providing a surface that can be driven on and does not disturb the topsoil layer.”

Plan Sheet D.3 further clarifies that topsoil disturbance is only permitted within the

Construction Limits. Topsoil may not be disturbed within the Construction Access Limits.

However, based on both Plan Sheet D.3 and observations during a recent site visit, the existing pathways within the designated

Construction Access Limits are too narrow to accommodate construction equipment or allow for transport of large materials, including the new pedestrian bridge, temporary work bridge, and other necessary materials.

Can we disturb topsoil with the Construction

Access Limits provided full restoration is completed post-construction? If not, how do we access the construction limits?

No, disturbance of topsoil layer is not permitted within the construction access limits as described in 201.03. Contractor to determine means and methods to gain access with equipment and materials without disturbing the topsoil layer.
