About this file

Written by GovTribe AI ·

This document is a set of architectural drawings depicting multiple design alternatives for dam facility modifications. The drawings show cross-sectional elevations at four key levels (1005, 988, 973, and 956) for the Unwatering Control Gallery 106 and associated structural components.

The document presents six distinct alternatives: Alternative 1A involves adding Unit 4 with fill at Bay 4 and opening skeleton Bays 5 and 6; Alternative 1B specifies adding Unit 4 with a bridge structure at Bay 4 and opening skeleton Bays 5 and 6; Alternative 2A adds Unit 4 with fill at Bays 4 and 5, a bridge at Bay 5, and opening skeleton Bay 6; Alternative 2B adds Unit 4 with bridges at Bays 4 and 5 and opening skeleton Bay 6; Alternative 3A adds Unit 4, an assembly bay, fill at Bays 4 and 5, and opens skeleton Bay 6; and Alternative 3B adds Unit 4, an assembly bay, bridges at Bays 4 and 5, and opens skeleton Bay 6. Each alternative shows the placement of new and existing structural elements including retaining walls, vaults, pavement, three-phase transformers, support structures, and rotor pedestals. The drawings include notation for existing fills, pavement, retaining walls, and access tunnels, with new construction elements highlighted in green shading across all elevation levels.
