This file is a set of technical drawings for the Bear Creek Service & Emergency Gates Replacement project at Bear Creek Dam in Lakewood, Colorado. The drawings (sheets M-001 through M-105) provide mechanical specifications and design details for the fabrication and installation of new service gates and emergency gates to replace existing infrastructure at the dam facility.

The project scope includes measuring and fitting new gates to current gate slots, repainting the inlet tunnel liner, gate slots, and marine door, replacing bonnet gaskets and O-ring seals in the main hydraulic gate hoist system, and replacing hydraulic oil piping for the low-flow gate between the new cylinder and flexible hoses on the hoist deck. Additionally, the low-flow gate cylinders require redesign, fabrication, shop-testing, and installation to operate the new service gates. The technical requirements are detailed in specification sections 05 56 09.00 26 (Gate Seals) and 35 05 40.14 10 (Hydraulic Hoisting Systems for Civil Works Structures). The drawings serve as the primary reference for contractors, with existing drawings noted as reference material only; actual gate slot measurements must be verified for accuracy during execution. All incidental related work is included within the project scope.
