NuMI MINOS Partial As-Built Drawings.pdf

This document is a set of architectural and engineering drawings for the NuMI Tunnels and Halls Project 6-7-4 at Fermi National Accelerator Laboratory. The drawings provide comprehensive technical specifications for underground tunnel construction and associated infrastructure components.

The project encompasses multiple tunnel systems including the Decay Tunnel, Absorber Hall, Absorber Access Tunnel, and Minos Access Shaft, along with various connecting passages and support structures. Key construction elements include concrete liners, steel fiber reinforced shotcrete, drainage systems, electrical conduits, and water supply/return lines. The drawings detail specific dimensions, material specifications, and construction methodologies for each tunnel section, including cross-sections showing concrete wall thicknesses (ranging from approximately 12 to 18 inches), liner attachment methods, shoring and bracing requirements, and excavation sequencing. Supporting infrastructure specifications address foundation requirements, rock support systems, ventilation provisions, temporary shaft support systems, and protection measures for personnel and equipment. The documents establish design standards referencing industry specifications including AISC, ACI concrete standards, and ASCE guidelines, with design coordination requirements outlined in the general notes. Additional details cover geotechnical investigations, survey data, utility routing, and construction access provisions essential for proper project execution.
