How BuildDesk Performs This Review
When an architect issues Addendum 3 with 12 revised sheets, material suppliers cannot afford to redo the entire takeoff from scratch. BuildDesk calculates the exact material delta—showing original quantities, revised quantities, and net change—so your quote desk can issue a fast, accurate quote revision.
- •Original bid drawings previously quoted (V1)
- •Revised architectural/trade drawings or bulletin sheets (V2)
- •Previous takeoff sheet or quote line items (if available)
- Overlay original and revised plan sheets to locate altered floorplates or partitions
- Re-measure modified areas and recount modified fixture/material symbols
- Calculate original quantity vs. revised quantity with net delta
- Document sheet citations and revision cloud references for every change
What You Receive
Comparative schedule showing original quantity, revised quantity, additions, deductions, and net variance.
