Record Drawing Index.docx

This is a Record Drawing Index documenting the original shop drawings, design drawings, operating machinery drawings, erection plans, and machinery house drawings from the 1934-1936 construction of the Cape Cod Canal Railroad Bridge. The index lists over 150 detailed shop drawings from 1935 covering all major components of the vertical lift bridge including grillages, tower spans, counterweights, lift span elements, machinery houses, platforms, railings, and operating equipment. It also includes the original 15 Corps of Engineers design drawings from 1934, 14 operating machinery shop drawings from 1934, 15 erection plan sheets from 1935, and 3 machinery house drawings from 1936.

The drawing index provides a comprehensive catalog of the bridge's original construction documents, which will be relevant for the current solicitation's painting and steel repair work. The detailed nature of these drawings, covering structural, mechanical and architectural elements, offers bidders important reference documentation about the bridge's design and construction. This is particularly important given the requirement to maintain proper bridge balance during repairs and coordinate with ongoing rail operations.
