Introduction

📌 Estimators should track these updates in real time to maintain accuracy.
✅ MSBS 5-anthra drawing transformation process
1. We compare each new version using Bluebeam Revu
When customers send update photos, we never change "eyeball".

We use comparative Bluebeam's BlueBeam:
Overlay old vs new sheets
Highlight the difference in red/green color
Even find out the smallest changes (piping, walls, fixtures)

2. We mark important scope changes for clarification

If any change introduces:
A new detail section
Unbelled Equipment
Missing dimension
We flagged it immediately to send an RFI to the contractor - before we continued with the final assessment. Material takeoff

When the change is confirmed, we:

Open the updated PDF in Planswift

Calibrates new sheets

Remove old starting areas

Add/Adjust New Volume
