MARINA CONSTRUCTION 2000 "No matter what you want to do, something else must be done first." Reconstructing the East seawall in Yacht Works' Harbor and rebuilding and remodeling Building 3 required removing old concrete slabs, the old timber seawall, and dredging out part of the harbor. Launch wells (for the Travelift) needed to be blasted out of bedrock and dredged to a control depth of twelve feet below low water. You can click on each photo below for a full sized picture.

These two photos show a "Hot Shot" blasting through the surface. For over a week, Harbor Construction's blasting crew drilled in the morning and in the afternoon blasted bedrock under the old and new launching wells, out to beyond the service dock. Every afternoon there would be three blasts of an air horn, and BANG!!! the earth would shake. The first few days it startled the heck out of us in the store and office. Here's a movie of the blast. Only this "shot" broke through the surface of the water. (By the way, we never did get used to the unannounced blasting.)
Once underwater blasting was done, the crew moved onto land. By then there was a fresh cover of snow. (right) Here you can see the drill used to place dynamite 6 to 12 feet down in the rock prior to blasting. - Underwater drilling was done from the barge rig on the left of the left picture. (Using the same drill rig.)
