The Principals of Cummins | Cederberg served as project manager and senior engineers for the coastal and marine components of the Rancho Grande Development located on the north coast of Colombia east of Cartegena.
The project included 2 miles of coastline, a 100+ slip megayacht marina, and internal lagoon and canal system. The scope of work included work shops, statistical analysis of wind and wave data, wave modeling, sediment transport analysis, water quality modeling, beach design and coastal structure design.
A combined site visit and workshop was conducted to evaluate the coastal processes as well site opportunities and constraints relative to the proposed master plan.
The internal lagoon was an important component of the master plan in order to create a marina village and additional waterfront to increase real estate value. However, in order to ensure adequate water quality, studies were performed evaluating the water circulation throughout the canal system.
Offshore wind and wave data were acquired and a statistical analysis was conducted to evaluate both normal and extreme conditions. Coastal design of structures or potential flooding is generally associated with extreme conditions, while water quality and sediment transport are generally governed by long term conditions.
Different design alternatives were developed reflecting various levels of investment and the potential for phasing the construction.
A SWOT analysis was conducted for various alternatives along with estimations of construction cost.
