About this file
This is an architectural drawing for VD Cryostat Roof Decking as part of the LBNF/DUNE project. The drawing provides detailed specifications for a roof decking system composed of 530 total panels arranged in eight different sizes, ranging from 62.875" x 12" to 78.75" x 24", each 1.5 inches in height. Panel quantities and areas are documented in the floor schedule, with sizes marked 1 through 8. The design includes saddle clip attachments at each corner of all panels, with a total quantity of 2,120 clips divided between Type W44 (1,768 units) and Type W10 (352 units). The clips secure the bar grate bearing bars to flanges, with specifications for both W44 and W10 attachment types.
The drawing details span measurements of approximately 202 feet in length and 83 feet 11 inches in width, with nominal free spans of 47.17 inches. Structural dimensions are provided in both inches and millimeters for reference. Dimensioning and tolerancing follow ASME Y14.5-2018 standards. The drawing is prepared by Fermilab and dated 09/10/26, with drawing number FDC-0001043, scaled at 1/8" = 1'-0" for the layout plan and 1" = 1'-0" for section details. This document serves as the technical specification for roof decking material procurement and installation requirements for the cryostat structure.
