Get Every Discipline Coordinated — Without Pulling a PE Off Billable Work.
Send us a real project. We model and coordinate your mechanical, electrical, plumbing, and fire protection systems.
So your engineers spend their time on the work only they can stamp — while Excelize handles the modeling, cross-discipline coordination, and clash resolution behind it.
Uncoordinated Systems Cost More Than They Save
$0.0B Lost to rework every yearUncoordinated systems cost the industry an estimated $31.3B in rework every year. Fixing someone else's bad work always costs more than doing it right the first time.

Modeling to stamping — everything in between, handled.
Discipline Modeling
Mechanical, electrical, plumbing, and fire protection systems, modeled to your design intent and LOD — whichever disciplines your firm runs.
Multi-Trade Coordination & Clash Detection
Typically LOD 350–400 in Navisworks, so systems install clean the first time — across every discipline in the model.
Shop & Fabrication Drawings
Coordinated shop and fabrication drawings, ready for the field, for whichever disciplines apply.
Four disciplines, one coordinated model.
Your CPDs and PEs didn't earn their credentials to chase redlines. We model and coordinate your plumbing systems to your design intent and LOD — so they stay on design and stamping.

Without this, here's what stays the same.
Uncoordinated work always costs more to fix than it would have cost to do right the first time.
-
PEs stay stuck on production
Licensed engineers keep chasing clash reports and redlines instead of the work only they can seal.
-
Complex projects get turned away
Data centers, hospitals, high-rises — the highest-value work goes to firms with the bandwidth to take it.
-
Rework keeps eating margin
Field clashes, resubmittals, and change orders — fixing bad work always costs more than doing it right.
Drag to compare — uncoordinated vs. coordinated
Engineers spend their time engineering.
Deadlines get hit — without pulling a single licensed engineer off the work only they can seal.
- PEs on design and sealing — not clash reports
- Complex projects accepted, not turned away
- Coordinated models — installed clean the first time
