As a part of its water and wastewater infrastructure asset management program (AMP), The Town of Millsboro converted decades of paper based utility maps and data into digital datasets using GIS technology. Digital infrastructure data was then overlaid with other pertinent datasets, enabling the use of spatial analysis techniques for the development of probability of failure, consequence of failure and risk assessment models. The AMP incorporates these models as tools to help prioritize funding needs. Water and wastewater maps are available from cloud based data services allowing for data viewing and editing on both desktop and mobile devices.

Verdantas performed construction review services for the newly constructed Museum of the American Revolution in Old City Philadelphia, two blocks away from Independence Hall and the Liberty Bell. The museum took two years to construct and opened in April 2017. One of the interesting parts of this project was an archeological excavation which was performed during the basement excavation. The National Parks building, which was removed to clear the site for the museum construction, had been built over the old houses which dated to the 1700’s. As part of the excavation for the new foundations which extended to as much as 20 feet below the streets, archeologists exposed the old structures and removed artifacts for months before foundations were constructed.

To support tourism and recreation while restoring maritime history, the City of New Castle embarked on a waterfront redevelopment project. The project’s focal point was a new dock to service the historic vessel, Kalmar Nyckel, other visiting tall ships and Forts DuPont and Mott Ferries. The new dock replaced a pier that was destroyed by Hurricane Sandy and, therefore, design and construction needed to be robust to handle the frequently harsh environment of the Delaware River. Ultimately, the dock was designed and constructed with a state-of-the-art pile foundation and substructure designed to meet the historic aesthetics and sustainability sought by the City.
