Azores Breakwater Repair
Baird assisted the U.S. Navy in response to a major breakwater failure protecting key US Military facilities in the Azores. Baird provided detailed assessment, design and management services from various stages of emergency repairs through a multi-year, 70 million USD permanent repair.

The breakwater had chronic damage since its construction in 1961 as a result of severe exposure to large North Atlantic storms, with a major breach occurring in 2001. Baird provided a detailed assessment of the wave climate, and designed a “hybrid” concrete armour unit/armour stone berm breakwater repair that satisfied requirements of limited annual repair funding and long-term degradation of the breakwater over its entire length while managing risk to critical military infrastructure protected by the structure.
- 600 meter breakwater repair
- 950 Core-Loc® concrete armour units – 32 MT each
- Aids to Navigation
- Develop a permanent repair for a structure that had been damaged many times.
- Design around a highly damaged structure with complex combinations of materials.
- Major construction cost, with limited annual funding allocations.
- Remote location and limited resources.
- Developed a detailed understanding the North Atlantic wave climate and that actual wave conditions breakwater experienced.
- Conducted a large scale physical model study at the Corps of Engineers CHL facility to evaluate and maximize the value of existing damaged structure in repair.
- Developed an incremental design solution that could be increased season by season with minimum mobilization costs.
- Utilized a hybrid design of local rock and concrete amour units to minimize cost and support the local economy.
