Another post from my Fortress of Solitude...

Photobucket has been resizing my images and forcing them to about half their resolution. I just noticed this today. For new posts the problem should be corrected, but I will have to see if I can resolve the issue for the old posts. I will post a message when this is done. Apologies.


Hybrid Deck Study: Empirical based model of TOS 1701 deck placement based human interface and Alan Sinclair's Revision-D port-side diagram: 24 deck arrangement

--- Purpose

To derive a plausible overall Deck Placement design within the confines of the modern fan based plan reconstruction of Alan Sinclair (AS) using Canon 11' TOs 1701 studio model window placement and typical human height as metric indicators. As a starting basis we begin with the "hybrid" FJ based deck plan from the previous study as a falsifiable hypothesis.

--- Process

Continued on from the 'FJ-AS Hybrid Deck Study' procedures.

Corrected the lower sensor dome undercut that had been overlooked in previous work.

Created simulated humanoid figures 15 pixels (5.87') high standing, 11 pixels (4.30') seated. 16 pixel standing height was not selected as it would have been 6.26', and the number selected would better represent both sexes typical height biased towards a larger number of males.

Replicated and positioned these figures to best approximate optimal viewing angles from pertinent windows, portholes, and other areas of interest. Where possible the figure was adjusted to optimize viewing for figures somewhat taller or shorter than the simulation.

Repositioned the locations of deck plates to best match the position of the representative figures. Avoiding prohibitively low deck heights (less than 6') and not intruding on window "frames" were additional factors used for adjustment. Additionally the location of certain key decks (hanger bay, etc.) were used for guidance in overall positioning of adjoining decks.

For decks where windows of various heights were present, added theoretical raised platforms and decks to represent split- or multi-level design.

Added some theoretical decks where appropriate, to possibly explain various inconsistencies or inadequacies of existing plans, or to explore possible designs.

Copied the original file.

Replaced the Port view with a mirrored AS Starboard view (to avoid having to mirror the FJ cross-section and make consistent viewing possible).

Added a few additional representative figures where appropriate.

--- Analysis

In retrospect using the Port side AS view was a minor mistake. This was done because the FJ cross-section and side view are from Port. AS accurately depicts this side of the model which, because it was the unfilmed side, is not detailed to the same level as the Starboard side (which has more windows on Decks 6/7, for example). An additional starboard view diagram is necessary to check for inconsistencies. If one were recreating the studio model it becomes an issue if one wants to faithfully replicate these asymmetries as intentional design, or mirror the Starboard side to avoid repeating production errors.

I did not keep track of positioning of decks, mainly because there was a great deal of trial-and-error involved and secondly because the effort required to record all these changes is not compensated for by third party participation at this point (i.e., I'm not sure anyone is reading these essays).

The current position for the Bridge deck plate may need minor adjustment, based on analysis of minimal turbolift ceiling height. Additionally, whether the turbolift can drop directly into the main vertical turbolift shaft, or requires a slight horizontal run, is a possible issue with the FJ arrangement.

Deck 2 arrangement seems plausible, in a Pilot configuration (briefing room), depending upon further alternation of Bridge height. Impact on production Lab central ceiling height is potentially an issue.

There definitely seems to be space in the outer hull for two full decks, but whether Decks 5-7 are all of the appropriate height needed to correspond to the physical sets is a different matter that feedback would be appreciated on. The undercut prevents direct access from the inner to outer portions of Deck 7 except at the Interconnecting Dorsal or Impulse Engineering (assuming it is split level like the Engineering set).

The exact arrangement of Primary Hull Deck 11 is flexible, and ultimately dependent on whether or not it is decided if it is compatible with the depiction of Phaser Control and surrounding areas in the series. Turbolift access probably cannot be directly vertical from the main shaft, unless the FJ location is adjusted slightly.

Primary Hull Deck 8 has "windows" of an unusual height (below typical sitting level), assuming we do not make Deck 9 shorter than it already is. Dropping the deck would solve the viewing angle problem but would make it impossible for typical humans to access Deck 9 while fully upright.

Deck 9 is listed by TMoST and FJ as fabrication facilities, yet it has many "windows". FJ does not provide access to all of these windows, despite putting in transparent "skin" areas. It may also have airlock capability, as there are door-like shapes.

Ceiling height are generally generous with the possible exception of Primary Hull (PH) Deck 9 & 10 and Interconnecting Dorsal (ID) Decks 8-10. Ceiling height on PH Deck 9 and ID 8-9 is an adequate 6.26' (as could be PH Deck 11 under one interpretation of deck location), while PH & ID Deck 10 are 6.65' which would accommodate most humanoids. With the exception of PH Deck 10 (which houses a cargo transporter and cargo bays) and ID Deck 10 (which is an observation lounge) these areas are designated for fabrication, machinery, or access (gainway & turbolift shafts). These are probably sparsely inhabited and/or automated. The ID Deck 10 observation lounge could have its ceiling height in creased by decreasing ID Deck 9 to below acceptible height. On the other hand, a small observation lounge and cargo deck with a low but adequate ceiling height is probably acceptable for all but the tallest crew members.

Some of the other observation lounge decks in the ID have potential issues with window height. FJ depicts these as seated lounges. In the case of Deck 11, for example, this would cause a ceiling height issue in relation to the next deck, once the deck was adjusted for a seated view from the windows leaving little room for upright locomotion. Ultimately I resolved these issues by using elevated platforms for the seated areas, allowing people to stand upright by the windows while being at a similar viewing height to seated occupants. Deck height was not very consistent, and other than for the areas that have minimal occupation there seemed to be little logical reason for the differences. If one disagrees with the use of platforms, then shifting the deck plates would be the logical option, and as mentioned there is the possibility that issues could occur.

In the secondary hull there are multiple examples of what appear to be different window heights on the same deck. While many of these can be explained away as examples of seated vs. standing viewing design, in other cases this can't be done. Adding a few raised platforms resolved the issue without causing more serious problems (such as deck height). If one disagrees with the use of these platforms this would require the use of multi-level decks which complicates the overall arrangement but FJ essentially had already done this in the BoGP Deck 19 (presumably for different reasons).

Repositioning of Secondary Hull decks 19 and above makes all of Deck 19 consistent with the hanger bay deck, and Deck 15 becomes a bit more reminiscent of the Engineering compartment we see in ST:TMP.

In the sides of the hanger bay there appear to be various observation windows. This implies either a series of decks, partial decks, gangways, or ladders -- out of sight through the lateral access points.

I made a theoretical extension of the deck above the actual shuttle bay, extending it out to below the dome above the hanger doors. The basic concept is that the hanger bay is double hulled, and that the walls and ceiling we see from inside the bay are not the actual outer hull. This would certainly add strength to the design, as well as increase safety under battle conditions.

The only explanation I have for the apparent "windows" on the nacelle pylons is that they are intended as observation ports when the ship is severely damaged (blind and dead in space) for use by engineers ascending to the nacelle to visually examine the ship for exterior damage. But their placement would make this difficult or possibly impossible for most/many parts of the ship, particularly the nacelles, especially since the inboard of the pylons seems to lack them. Of course, its possible that they are not windows at all.

--- Conclusions

The FJ / TMoST-Writer's Guide (text description) of the number of decks for TOS 1701 seems plausibly consistent with the actual 11' studio model, as reconstructed by Alan Sinclair. Overall this deck arrangement seems plausible on the basis of this examination. If the ceiling height of particular sets makes it necessary, some adjustment could still be made, but ultimately there is a limit to how far this layout can be adjusted without causing serious additional problems. If the ship were 1080' long this would provide 14% additional space for excessive ceiling heights or to adjust deck spacing. However, it seems clear that 947' is an appropriate length for the ship, as dictated by the bulk of supplemental production materials. Several area that have been noticed as having "issues" with an 11-deck arrangement all seem workable with this current, hypothetical arrangement.

The interesting conclusion drawn from this is that whoever created the Writer's Guide / TMoST text describing the decks of 1701 seems to have planned out the 24 deck arrangement very well in relation to the studio model. How else do we explain that the two (presumably) least inhabited decks of the Primary Hull end up having the lowest ceiling height when we derive their location from window placement? What is perhaps more interesting is that FJ, despite the fact that TMoST doesn't give a detailed description deck-by-deck description of the Secondary Hull, continues on with this description and continues to make allocations that this analysis point to as meaningful while his own plans fail to do this. Somehow FJ has the Secondary Hull decks with the least ceiling height (8-9) end up being allocated to (presumably) automated machinery and storage. For all these decks, with the exception of ID Deck 10 (where FJ matches this estimate), FJ shows in his cross-section greater ceiling height, and generally seems to be aiming for a consistent ceiling height. From FJ's depiction of 1701, Deck 9 with its windows would presumably make a better observation lounge or office space than an auxillery machine room. Yet its not.

FJ's window placement is not particularly accurate, nor is his shape or size for the secondary hull, nor does his position of the 24 decks exactly match those derived here -- so it seems unlikely that he could have reached the same conclusions with the materials he had access to and the interpretations he seems to have made as have been made here. One possible explanation is that FJ got access to a document that provided information on the contents of each secondary hull deck. Why, if this existed and was available to the shows writers (as the description of the primary hull was in the Writer's Guide), this didn't appear in TMoST is a mystery. Of course, this is only speculation, it may simply have been pure luck. If such a document did exist, then it would clearly indicate that a well-planned out 24 deck version of the ship was more than an oversight or a mistake dumped into the Writer's Guide.
