General Scope of Construction Project
The Cuddebackville Dam Removal Project involves the removal of two dams on the Neversink River in New York. The first dam was constructed of logs and dirt embankment in the 1830s, and the second dam, a reinforced concrete structure, was constructed in the early 1900s.

Mr. Welch (CMEC) participated in the design phase of this project with the Pennsylvania District USACE and executed the work under an 8(a) sole-source award program.

Summary of Mr. Welch's (CMEC) Role in Project
Mr. Welch (CMEC) provided on-site management, supervision and craft labor for the installation and removal of temporary construction features, as well as the complete removal of the dam on the Neversink River.

Mr. Welch performed contractibilty reviews during the design phase, construction of an access road, the installation of two cofferdams to divert stream flows, and the demolition of the existing dam structure using coventional means in support of the restoration of the habitat of the Neversink River.

Specific concerns were addressed with regard to downstream turbidity and its effects on the dwarf wedge mussel as well as other fish habitat. Although these mussels have not been found in the are of the dams, they are known to exist downstream from the project. The Never sink River's migratory fish patterns require that the in-stream activities be conducted during the summer and early fall months, July through October.

In addition to Mr. Welch's consulting role in the project design, he worked with the USACE and the Eastern New York Nature Conservancy to develop a Quality Control Plan, Site Specific Safety & Health Plan, Evironmental Protection Plan, Habitat Protection Plan, Waste Management Plan, Temporary Construction Plan and Removal Grading/Restoration Plan.

Extent and Type of Design Work Subcontracted
The design was developed by the Engineering Branch of the USACE Pennsylvania District in cooperation with the Nature Conservancy, the Orange County Parks Department, and the New York Endangered Species Department. Engineered Demolition, Inc., under the direction of Mr. Bill Welch, performed contractibility review on the design package as it was developed.
