Gun Point Harbour Development
Gun Point Harbour is located on a remote island in the southern Bahamas. The Government of Bahamas wanted to improve access to the island for local inhabitants, promote economic development and provide a new southern naval patrol base.

Access to the island is limited due to the lack of suitable landing facilities. The small harbour's primarily purpose is to accommodate a scheduled cargo (mail) boat, Bahamian Defense Force patrol vessels and a high speed RO/RO ferry. Highlights of the design include:
- Harbour basin excavated into land and designed to survive hurricane
- N and S breakwaters protect basin from waves and limit sedimentation
- 120 m long quay wall accommodates 35 m mail boat and 60 m patrol vessel
- Schedule constraints required a fast track schedule for planning and design.
- Limited geotechnical information available.
- Adequate armour stone was not locally or regionally available.
- Manage complicated navigation through reefs and shoals.
- Multiple meetings with key stakeholders to obtain “buy-in” and facilitate approvals in parallel with other critical tasks.
- The quay wall design accommodates various subsurface conditions.
- Locally cast Core-Loc® concrete armour units were incorporated into the design.
- Aids to Navigation were developed and implemented.
