Drawings
Specifications
The Specifications tab, next to Drawings in the plan drawer, is a place to file written specification documents — the trade specs, material schedules, and performance requirements that come with a drawing set. It's worth being direct about this up front: specifications are agent context only. There's no reader, no viewer, and no way to open a spec inside Estimator+. If you're looking for a way to read one on screen, it isn't there — that's by design, not a gap.
What it's for
Specs exist so your connected AI agent can search and cite them while it works. When you ask your agent to draft scope for a trade, it can cross-reference the relevant spec clause and quote or paraphrase it — the same way an estimator would flick to the spec book while reading a drawing. You get the benefit of that cross-referencing without needing a spec viewer of your own, because you're never the one reading the spec directly — your agent is, on your behalf, connected through the What the Intelligence Bridge is.
Uploading
Drag PDFs onto the Specifications tab to file them there directly — there's no folder structure to manage; every upload lands in one list for the project. Like drawings, every spec you upload is read automatically and at no extra cost, with the same progress meter and ✦ Read by AI badge you'd see on a drawing sheet.
Files that arrive as a stack of A4 pages dropped on the Drawings tab trigger a Specification or drawings? prompt instead of landing silently in the wrong place — see Upload drawings for that flow. Dropping directly onto Specifications skips the prompt; it's already decided.
Drawings win
When a specification and a drawing disagree, or when a spec seems to call something up that the drawings don't show, drawings take precedence. Specifications tend to be general documents — the same clause about, say, waterproofing membranes often gets reused word-for-word across several unrelated jobs by the same consultant — so they're read as a supporting reference, not the final word on what's actually being built. Your agent treats them that way too: cited where they add something real, never allowed to override what the drawings actually show.
