Final Design of Route 628 over the Mattaponi River

VA

The purpose of this task is to perform the final design of the superstructure replacement of Route 628 over the Mattaponi River (Str ID 10620, VA No. 6912).

VN Engineers is leading a field investigation to map out substructure deficiencies and perform the final design for the substructure elements to be rehabilitated and reused. Substructure elements will be accessed via the approach embankments and a kayak.  The bent cap for Bents 1 and 2 will not be accessible for sounding.  The bent cap for Bent 3 and the Abutments will be sounded.  Deficiencies will be mapped out on sketches in the field and will be used to develop the final design repair plans for the substructure elements.

VN will support Jacobs in the final design for the substructure repair and rehabilitation plans.  Design verification of the reinforced concrete section will be performed using existing FB-Pier Models.  VN will support in this effort and develop rehabilitation details as required. Substructure rehabilitation effort is anticipated to include pedestal reconstruction, spall/crack repair, embedded galvanic anodes, and application of a clear penetrating sealer over all concrete faces.  VN is also providing quantities for the substructure elements to assist in the development of the cost estimate for the project.

Statewide Bridge Structural Health Monitoring Lord Delaware Bridge, Westpoint, VA

The purpose of this VDOT project is to investigate the structural conditions of the Lord Delaware which carries Route 33 traffic over the Mattaponi River between King and Queen County and the Town of West Point in King William County. The goal of this analysis is to identify bridge beam locations that need future repair.

VN Engineers’ scope under this task order is to provide Traffic Control Plans for the protection of UBITs during the inspection and NDE work. VN Engineers is exercising due Standard of Care in the development of the traffic control plans. VN tasked to conduct a single site visit to confirm existing conditions along the bridge and the approaches to inform the development of the traffic control plans. The VN team is also responsible for traffic control plans for the protection of the inspection equipment and personnel along the Lord Delaware bridge. Traffic control sheets will be developed from existing aerial mapping of the site.
