Dredging Quality Management (DQM)

Effective immediately, DQM is transitioning qualifying pipeline dredges to a two-year certification cycle. The new schedule applies to currently certified dredges, as well as new and renewing dredges, that maintain satisfactory data transmission, data quality, and compliance with applicable DQM specifications and requirements. Full on-site inspections will generally occur every 24 months, supported by continuous data review and an interim validation approximately 12 months after the last successful on-site inspection. DQM will contact affected contractors directly regarding revised certification dates and interim-validation requirements.

Updated DPIP punch lists are posted for hopper, pipeline, mechanical and scow plants, all now in one common format covering everything a plant’s instrumentation plan must include.

Information about past and upcoming dredging jobs that was previously published on the Dredging Information System (DIS) is now available here. Open solicitations, awarded contracts, and dredging schedules are on the Reports pages. Data reconciliation and clean-up is still underway and more reports and functionality will be coming in the near future.

The consolidated DQM specification has been updated to include minimal text updates to improve clarity and intent. It is now published in three formats on the Specifications page: PDF, Microsoft Word, and SpecsIntact — available to download now, ahead of its inclusion in the Fall update of the Whole Building Design Guide (WBDG).
