One person's rendering of public records, not the Washington State Convention Center Public Facilities District's, the State Auditor's, or an accounting firm's. Accuracy is not guaranteed. Every figure opens the page it was read from, so check the number against the page.

What the buildings hold
| Floor plans | 2 | the District's booklets for the Arch (2024-01-22, 12 pages) and the Summit (2026-04-13, 16 pages), registered as documents with every page rendered |
|---|---|---|
| Event log | 1 | the District's own log, produced with the facility-utilization records response of 2026-05-15 |
| Events | 952 | |
| Bookings | 13,946 | one event in one space over its dates |
| Utilization figures | 36 | occupied, live and available square-foot-days, by building and year |
How it was built
Every square footage, dimension, ceiling height and capacity comes from the two floor-plan booklets, read from the tables printed under each floor drawing, as figures on a page like any other. The event log and the booklets were joined at research time into one denormalized table of who booked which space on which day, and the buildings book is seeded from that.
The rest is derived and regenerated from the loaded data. The Arch is two structures, 705 Pike and 800 Pike, joined by a skybridge and a truck bridge, and the booklet draws them on separate pages, so each floor is one row per structure. Combination names the log uses but the plan does not, Hall 4ABCD or Room 345-346, are given the floor their parts are on, and which spaces are made of which other spaces is recorded so available area is a query rather than a hard-coded number. The Arch's five circulation zones, each with its own entrance and 800 Pike drawn as two, the Tahoma level and the floors with the street door, are drawn as zones. Use by floor and use by zone are both built from the same day-level rows.
What is not settled
- The event log is a records response, not a page a reader can open; its figures carry the citation and the text, not an image.
- The utilization dataset is a computed file, not a document; its 36 figures are the May 2026 computation, kept for the record, and the derived views supersede them: the Arch's 2019 occupied share is 85.7 percent in that file and 74 percent in the views. Two guards in the rebuild disagree about which already-suppressed rows to count, and the difference is the gap between 78 percent and 74 for the Arch in 2019. The 22 days on which 800 Pike's street entrance opened in 2025 is a count made by hand from the log, excluding events that checked in elsewhere; the views give 44 lower-floor live days, the floor under it, not a replacement.
How to check a figure
Click any floor or space and the page of the booklet that draws it opens, at full size, with the booklet's title, date and page number, and the capacity table read off that page. Occupancy figures trace to the event log by event and space. The booklets and the log are public records of the District; they are not hosted here, and the citation tells you which one to ask for.
The rows themselves are readable one table at a time, at /api/data/zones/ and the like, read-only. The database schema and the queries are shown; the generator that produced the pages is not published.
