About this file

Written by GovTribe AI ·

Attachment J-9 is a detailed projection diagram for a Window SEG (Silicone Edge Graphics) Projection Study for a 9'-7" case, created on 2-22-2023. The technical diagram provides precise measurements and specifications for projection setup, including multiple critical dimensions such as projection height (95.5" cropped, 124" full), lens center positioning, and projector placement parameters. The diagram includes silhouettes of figures to demonstrate scale and positioning relative to the projection area, with specific notes about lower projection limits and recommended placement.

The projection study appears to be part of the Library of Congress's Treasures Gallery exhibit design for the Founding Phrases exhibit, which will explore the Declaration of Independence's legacy. The technical diagram suggests meticulous planning for media installation, with careful consideration of projection angles, heights, and spatial relationships to ensure optimal viewer experience. The document is labeled as part of the 030ADV25R0023 solicitation for Audio Visual Design Services, indicating it is a technical specification supporting the broader exhibit design contract.
