27. The Environmental Challenge
Sediment and Erosion Control
Construction Access
Hazardous Materials
Turtle Lighting
Community Impacts

28. The Environmental Challenge
Joint Environmental Inspections
Contractor and DOT Contractor has a full time environmental inspector on the project
Full Time SCDOT Environmental Consultant
Together, the team of environmental professionals functions to ensure environmental compliance and to expedite the environmental process.

29. Sediment & Erosion Control
Approximately 2 miles of silt fence, 10 temporary sediment basins, and several check dams among other control measures are installed on the project.
Contractor and SCDOT have strict inspection processes in place to monitor erosion control measures.
Inspections weekly and after every .50” rain

30. Temporary Sediment Basin

31. Construction Access
A total of 3 temporary construction trestles were erected for the project.
Greatly minimized impacts to wetlands while still allowing construction access.

33. Hazardous Materials
SCDOT has remediated five UST’s, disposed of more than 100 cubic yards of contaminated material, and abated lead based paint and asbestos from structures ranging from houses to bridge.
During the construction of the CRB, SCDOT has spent an additional half million dollars for handling of hazardous materials/waste encountered during construction.

34. Pumping material from an abandoned UST encountered in the Charleston Interchange.

35. Potential Turtle Impacts
Concerns raised that bridge lights may disturb loggerhead hatchlings
Aesthetic Lighting Modified
Lights are controlled by timer
Lights may be dimmed
Lights may be turned off

36. Community Impacts
Nine homes within the project ROW were relocated for affordable housing.
The homes were placed on new foundations at various sites in the community and are being renovated through a partnership between SCDOT and the City of Charleston.

39. Lessons Learned Include the Draft Contract with the RFP
Include Schedule of Values in Contract
QC/QA - Trust but verify
Independent Assurance by DOT
Be sensitive to the community concerns
Make Partnering a Key Element
Establish Lines of Communication
Time really is money – make decisions quickly

40. LAST LESSON LEARNED

41. BE CAREFUL OUT THERE…
You never know what you might find.
