Drafting - L3AV Standard Reference Drawings

DESCRIPTION

The attached drawing set should be considered the gold standard regarding the information that should be present in a standard drawing set. While it may not be practical for every project to include this level of detail, it shall be considered L3AV best practice to adhere to the standards shown here as much as possible.

NOTES

This drawing set incorporates nearly every best practice as defined by the L3AV drafting standards documentation. The attached reference drawings are taken from an existing L3AV project and have been edited to remove identifiable client information. Notable mentions here include:

  • Notes that are shown on a given page apply only to that page/room. There are no extraneous or unused notes.
  • All detail callouts (elevation, section, riser, etc.) are dynamic and can be clicked on to take you to the relevant section of the drawings.
  • All drawing pages are cross-referenced to corresponding pages via the use of dynamic page callouts.
  • Architect-provided background and elevation drawings are used for all facility drawing pages (TA2 and TA4 pages).
  • All equipment placed on the TA2 & TA4 pages has been identified with unique SYS-IDs.
  • The riser diagrams are painstakingly detailed yet easy to follow.
  • The TA5 pages include not only details for service panels and disconnect panels but also include all of the custom plates.
  • SYS-IDs use the '-###' suffix to allow for each room to have unique identifiers from every other room. SYS-IDs expand to a '-####' suffix once the room count goes into double digits.
  • Cable labels use the '...####' suffix to allow for each room to have unique identifiers from every other room. Cable labels expand to a '...#####' suffix once the room count goes into double digits.
  • On the signal flow pages, every App Layer Note and Install Note is referenced on the drawings for easy identification of where the note applies.
  • All flags on the sig flows that refer to a different area are either located outside of the bounding box or clearly identified when inside the bounding box. Additionally, all off-page flags give a clear reference for where they go.
  • Space is optimized on the sig flow pages. Equipment placement is maximized per page while still keeping everything organized and neat.
  • Rack elevations include all rack accessories, and the accessories that require power are also reflected on the power calc tables.
  • TA9 pages have been included to show the video wall presets that will be included in the design.

One feature of this drawing set that doesn't quite conform to out typical standards is the page numbering system. While the numbering system used is fine for this particular set, it should not be considered the standard for the majority of L3AV drawing sets.
