The Columbia River Consolidated Materials Dredging Project consisted of dredging 1.2 million cubic yards of consolidated materials and boulders to -51 MLLW in the area of river mile 105.

Marina del Rey, considered the largest man-made marina in the world sits just north of the Port of Los Angeles and just to the south of Venice Beach.  In 2007, J.E. McAmis removed more than 255,000 cubic meters of material from the entrance channel of Marina del Rey and transported the material via dump barge to a near shore disposal area adjacent to Dockweiler Beach.

The Riverbed Gradient Facility, Sacramento California.  Over 180,000 cubic yards of cementitious river rock was excavated.  Approximately 240,000 tons of riprap was placed between a series of sheetpile walls which formed the cells to create the gradient structure.  The primary focus of this project was to create a 1,500 x 750 foot structure to protect migrating salmon from nearby intake pumps used by a local irrigation district.

The Ice Harbor Dam Project on the Columbia River consisted of drilling, blasting and dredging more than 115,000 cubic yards of Basalt in more than 20 feet of water. With drilling, blasting and dredging operations taking place only 100 feet from the face of Ice Harbor Dam, vibration control was a vital project component. Working around the clock in difficult seismic and environmental conditions, J.E. McAmis was able to successfully deliver the project 15% ahead of schedule with a zero incident, safety and environmental record.

The Port of Anchorage Maintenance Dredging Project was completed in 2000.  J.E. McAmis dredged approximately 1.9 million cubic yards in heavy ship traffic, and in 38 foot tides and extreme currents.

St. Paul Island, AK Harbor Improvements Phase II is located in one of the most harsh and remote environments in the Bering Sea.  J.E. McAmis' PC 3000 Dipperdredge, Megan-Renee, excavated more than 400,000 cubic yards of hard rock, cemented boulders and sand, as a subcontractor to Kelly-Ryan Construction of Seattle, WA.  The dredge crew worked around the clock in extreme sea conditions to bring the project home on time and within budget.

The Osprey Platform Pipelines Stabilization Project was performed in the Cook Inlet, AK for the Forest Oil Company.  The objective of the project was relocation and stabilization of three (3) high pressure production lines, without interrupting production.  Stabilization was achieved by relocating the lines into a series of trenches which were constructed by dredging through a rock formation which lay between the Osprey Platform and the terminus point.  This project required precise positioning and hydraulic control.
