Sheet S-001: Whole-House Axonometric Key — Roof Levels Above the Main-Column Bases

What this sheet shows

S-001 is the whole-house structural arrangement, drawn as one axonometric key view at scale 1:200 on A1 (841x594). Grids A01 through A19 are labelled along the frame. On that view, two schedules each carry the heading ROOF LEVELS ON THIS SECTION (mm ABOVE DATUM). Every row is a Y station with a bearing level and a finished level, both in millimetres. Each schedule closes on the same datum sentence: the project vertical datum is the main column bases, model Z = 0, printed as Z = 0.000 mm. The first schedule lists Y=-338, Y=0, Y=6000, Y=6338 and Y=6260.82. The second repeats Y=6000, Y=6338 and Y=6260.82, then continues with Y=12000, Y=18300 and Y=18638. The grid bubbles do not restate those levels, and the title block does not either.

How the two level schedules fit together

Where both schedules name the same station, the figures match, so either block can be checked against the other without leaving the sheet. Y=6000 is bearing +7320.0 and finished +7421.6. Y=6338 is bearing +7326.8 and finished +7428.3. Y=6260.82 is bearing +4702.8 and finished +4804.3. That third station lies between Y=6000 and Y=6338, yet its bearing level is +4702.8 beside +7320.0 and +7326.8. The sheet is listing two levels across those Y stations, not one sequence that changes smoothly from row to row. At Y=-338, Y=0, Y=6000 and Y=6338, bearing runs +7193.3, +7200.0, +7320.0, +7326.8 and finished runs +7294.8, +7301.6, +7421.6, +7428.3, and each step in that list is an increase. At Y=6260.82, Y=12000, Y=18300 and Y=18638, bearing runs +4702.8, +4588.0, +4462.0, +4455.3 and finished runs +4804.3, +4689.6, +4563.6, +4556.8, and each step in that list is a decrease. Y=6338 still carries the higher pair even though its Y is greater than Y=6260.82. At every station the finished figure is the higher number on the row. The sheet does not state a build-up thickness in words; it prints the pair.

What the key view keeps, and what it sends elsewhere

The notes keep this drawing a key to the arrangement. All dimensions are in millimetres, and the sheet says not to scale the drawing, even though the title block gives 1:200 on A1. Member sections and materials are on S-600, not as labels on the axonometric. Connection references are S-601 to S-606. Design conditions are in the accompanying structural technical notes. A careful reader uses this sheet for the grid run and the two level schedules, and goes to those documents for a size, a joint or a design condition. The levels are stated here as millimetres above the main column bases. Section sizes and connection details are referenced outward rather than called out on the view. The same issue sits in the structural public edition, with the reference-design context under fire, structure and site.

Status

The title block reads K&K Data / PIN001, structural drawings, sheet S-001, revision 04 / 25 SEP 2026. The issue line is Design Development — Public Edition P1 / 2026-09, and dimensions are in millimetres. In that form the sheet is a reference design for study and evaluation. It does not record a completed building. It also does not fill in the items it has already sent to S-600, to S-601 to S-606, and to the accompanying structural technical notes.
