The questions that come before the product.
Definitions and working answers from inside the workflow — every example drawn from real anonymized projects, every finding verbatim from delivered review sheets.
What is drawing reconciliation?
Drawing reconciliation compares related project information across plans, schedules, specifications and details to find conditions that deserve review before they are priced or built.
Read the answer →Why doesn't a door live in one document?
A single commercial opening is described by the floor plan, door schedule, hardware schedule, specification and details — and estimating it correctly means reading all of them together.
Read the answer →What's the difference between a door schedule and a hardware schedule?
The door schedule lists each opening's physical properties; the hardware schedule defines equipment sets. The mapping between them is where takeoffs are won or lost.
Read the answer →What is an architectural opening?
An opening is the complete assembly at a passage through a wall — door, frame, hardware, glazing and conditions — treated as one coordinated unit of project scope.
Read the answer →How do you review a doors & hardware bid package?
A reliable D&H package review structures the schedule, itemizes the sets, maps openings to hardware, applies conditional rules, and turns undecidable conditions into RFIs.
Read the answer →What causes hardware estimating RFIs?
Most D&H estimating RFIs come from five patterns: field-verification scope, conditional set language, room-function judgment calls, remark-driven exceptions, and missing manufacturer data.
Read the answer →What is project intelligence for AEC?
Project intelligence connects the information distributed across a construction project's documents into one queryable, source-traceable record.
Read the answer →How does conditional hardware language split scope?
One sentence inside a hardware set — 'only at,' 'restrooms only,' 'where scheduled' — can change quantities across every opening that carries the set.
Read the answer →What does 'existing to remain' mean for estimating?
ETR openings keep their existing door, frame or hardware — which makes them field-verification scope, not free scope, until site conditions confirm what's reusable.
Read the answer →How do you trace a takeoff number back to its source?
A defensible takeoff lets you follow any quantity back through the mapping to the schedule row, hardware item, and rule that produced it.
