Located along the banks of the Charleston Harbor with a spectacular view of the Arthur Ravenell Bridge in the background, the South Carolina Department of Natural Resources (SCDNR) Marine Resources Research Institute is in an ideal location for severe corrosion. The SCDNR determined that the large amounts of corrosion observed throughout this building needed to be addressed. 

In 2006, the SCDNR hired two engineering firms to conduct visual and nondestructive investigations of the cast-in-place concrete portions of the structure. Funds were allocated and, in 2008, the state of South Carolina solicited proposals for a design-build approach to perform a defined scope of work as outlined in the prepared program. 

The owners chose an engineer and contractor design-build team to perform all necessary investigations, evaluation, design, budgeting, and construction for the entire scope of work. This scope included structural concrete repairs to the wet lab areas; repair/replacement of the steel support clips for the exterior precast concrete wall panels; completely new energy-efficient exterior window and door replacements to meet current hurricane windborne debris impact requirements; completely new energy-efficient heating, ventilation, and air conditioning (HVAC) systems; replacement of the damaged exterior concrete stairs; and new isolation lab units in one of the wet labs. 

The concrete repair portion of this project was especially critical because of the volume of damage. By using the 2006 engineering reports and further detailed investigations in 2008, the team concluded that the use of several different corrosion mitigation strategies would be required, along with carbon fiber strengthening and conventional concrete repair methods. 

The overall schedule for the project required very close coordination with the researchers and spawning cycles of numerous marine species. Complete wet laboratories were taken out of service, and these fish had to be relocated. Working around the hurricane season also added to the scheduling and logistics challenges. The project, however, was completed on schedule and within budget, resulting in a successful outcome for the entire project team.
