PPM Services

Dredging & Capping Services

Pacific Pile & Marine has the specialized equipment and capabilities to perform a variety of dredging and capping services.

Dredging

PPM owns and operates an extensive range of dredging equipment that can be configured to perform standard dredge operations to environmental remediation and shoreline restoration. Our diverse fleet of barges, cranes, and excavators allows us to engage in complex projects that include the following three construction types:

Environmental

PPM is experienced in remediation for contaminated sites. We often team with environmental engineering firms to provide value-engineering and constructability reviews for owners. Our crews are certified to handle subtitle D and C material and trained in the use of bmps including the deployment of debris booms and turbidity curtains. Equipment is outfitted with GPS/RTK hardware and software designed to perform precise, stepped dredge cuts and engineered caps.

Maintenance

In addition to routine maintenance dredging, PPM is capable of performing specialized, in-marina, precision dredging utilizing shallow draft dredging equipment outfitted with RTK. The small footprint of our equipment allows us to reach difficult to access areas with minimal disruption to on-going maritime operations. We maintain portable, modular barges that can be transported for inland work as well. PPM owns a variety of dredging buckets including sealed environmental Young buckets, Jewel and Young re-handle buckets.

Disposal

PPM owns and operates a permitted transload facility located on the lower Duwamish River, a major Washington state waterway, allowing us to transfer TSCA and CERCLA classified material into trucks for disposal. PPM is experienced at transloading contaminated materials into containers, rail cars, and direct loading truck-and-pups. PPM owns and operates bottom-dump barges to deposit approved materials at state-approved open-water disposal sites. The bottom dump barges meet Department of Natural Resources requirements for the Open Water Disposal Site Use Authorization Permit and is capable of being loaded in shallow draft areas.

Survey

PPM performs hydro-graphic surveys to ensure consistent, accurate information throughout the dredging and capping process. Our hydrographic survey boat is equipped with a Reson 7125 multibeam capable of 0.5-degree beam widths and the Applanix POS MV IMU. Data from the boat can collected and processed in-house using HYPACK software. The information collected from the survey boat can be uploaded to our dredging software to identify areas needing potential corrections.

Capping

PPM’s equipment is frequently used for projects requiring environmental or engineered capping. The RTK-GPS system in-conjunction with the hydrographic survey boat can be used to place cap material to required elevations and slopes.
