Project Description: This historically significant project involved the construction of the new Harriet Tubman Underground Railroad Visitor Center in Church Creek, MD. The project consisted of four new buildings: a Museum and Exhibit Building, an Administration Building, a Storage Garage, and a Pavilion. The project was certified LEED Silver.

The site work was very challenging, as we were dealing with a wet site and related dewatering measures. The civil engineer was very sensitive to environmental requirements and the utility work was designed to meet the most stringent Maryland environmental laws. The storm system included grass swales, submerged gravel wetlands and bio-retention ponds. The sanitary system had features such as infiltration ponds, effluent pump station, aeration chambers and pre-treatment chambers. There was also a stand-alone fire suppression system, which included large water tanks, vertical turbine fire pumps and wet wells.

The hardscape work was designed to complement the historic, and rustic, nature of the buildings. There were very unique features such as exposed aggregate walks, tinted coquina stone pavements, reinforced turf and porous paving. The landscape package was equally impressive, and the landscape architect was heavily involved in the site appearance.

The buildings were designed to visually complement the history and life of Harriet Tubman. Exposed heavy timbers and glue laminated beams were installed. Other items included structural concrete; masonry and cut stone; structural steel and miscellaneous metals; millwork and fiber cement siding; zinc metal exterior wall panels; vegetative roofing; aluminum entrances and storefronts; specialties; and sprinkler.

The mechanical work was sophisticated. There were energy recovery units, heat pumps, humidifiers and geothermal wells. Electrically, the work scope included solar powered LED lighting, packaged engine generator, communications equipment and cabling, AV system, electronic safety and security, intrusion detection and video surveillance.

We were very proud of this museum and the quality of the workmanship. There were very few change orders and the project was completed on schedule. Our relationship with the State of Maryland was excellent and we were lauded for this project.
