RT Group, Inc. (RTG) was retained by the YMCA of Pawtucket to perform a visual inspection of the Quidnick Reservoir Dam. The YMCA had previously received a Notice of Violation (NOV) from RIDEM requiring an inspection by a qualified Professional Engineer.

Accordingly, RTG conducted a full RIDEM file review of the dam and performed a visual inspection. RTG then prepared a Visual Inspection Report that summarized the findings, and provided repair recommendations and implementation schedules.

Upon review of the report, the YMCA retained RTG to perform the design of the Phase 1 repairs which included performing detailed stability analyses, designing a counterweight berm, and elevating the crest of the dam to provide sufficient freeboard above the design flood.
