Fire Protection Hangers - Automated Pipe Hanger Placement for Revit

Key Features

Everything you need for efficient hanger placement

UNIQUE

🎯

Smart Clash Avoidance

Automatically detects AND avoids fittings, valves, flanges, and existing hangers. Other tools only detect - we prevent.

UNIQUE

🔄

Iterative Positioning

When a clash is found, the algorithm searches step-by-step to find the optimal position. Step size is configurable in CSV rules.

⚡

One-Click Placement

Place hangers on entire fire protection systems with one click. No more tedious manual placement.

📐

Code-Compliant Spacing

Follows NFPA 13, MSS SP-69, FM Global and other industry standards. Always audit-ready.

📏

Rod Length Calculation

Automatically calculates rod length to structural elements like floors and beams.

🔗

Instant Linked Model Detection

All fire protection systems from host AND linked models appear automatically when you open the app. No manual searching.

QA/QC

📋

Comprehensive Logging

Every decision logged: placements, clashes avoided, iterations performed, skipped pipes, and why. Full audit trail for QA/QC.

📦

Per-Diameter Family Selection

Assign different hanger families for each pipe diameter. DN25 can use one family, DN100 another. Full flexibility for your project needs.

🏆 What Makes Us Different

Smart Clash Avoidance Technology

Other tools detect clashes after placement. We prevent them during placement.

❌ Other Hanger Tools

Place hangers at fixed intervals

→

Run clash detection in Navisworks

→

Find 50+ clashes with fittings

→

Manually fix each one

⏱️ Hours of rework

✅ Fire Protection Hangers

Select systems and click Insert

→

Algorithm checks each position

→

Clash found? Auto-iterate 10mm

→

Clean model, zero clashes

✨ Ready for coordination

What We Check Before Placement

🔧

Fittings

Tees, elbows, reducers, couplings - no hanger will be placed on any fitting

🚰

Valves

Gate valves, check valves, butterfly valves - all detected and avoided

⭕

Flanges

Flanged connections are identified and given proper clearance

📍

Existing Hangers

Already have hangers? We won't duplicate or place too close

🔴

Other Pipes

Checks collision with ALL pipes in the model, not just the host pipe

🏗️

Structural Elements

Beams, columns, and other structural members in linked models

🧱

Walls

Walls from host and linked architectural models are detected

💨

Ducts

HVAC ductwork and other MEP elements that may intersect

📐

Clearance Distance

Configurable minimum clearance from all obstructions

🔗 Full Linked Model Support

Clash detection works across all linked Revit files - not just the host model. Structural, architectural, and other MEP models are all included in the clash check. True multi-discipline coordination.

🎯 Smart Filtering

Our algorithm intelligently ignores pipe insulation and duct insulation during clash detection. This prevents false positives and ensures hangers are placed based on actual pipe geometry, not insulation layers.

How Iterative Positioning Works

Tee

❌

Step 1: Initial position falls on fitting - CLASH!

Tee

🔍

Step 2: Move by iteration step, check again...

Tee

✅

Step 3: Clear position found - hanger placed!

Fully Configurable: IterationStep=10 (mm, adjust as needed) • ClearanceDistance=100 (mm, minimum gap from obstacles)

How It Works

Four simple steps to automated hanger placement

Select Systems

All fire protection systems automatically detected - including linked models

Instant detection: The moment you open the application, it automatically scans your entire Revit project - including all linked files - and lists every fire protection piping system. No manual searching required.

Host + Linked Models: Systems from linked MEP, architectural, and structural models appear instantly
Multi-select: Choose multiple systems at once for batch processing
Clear identification: Each system shows its source file for easy identification

                                💡 Why this matters: Other tools require you to manually navigate linked files. We show everything in one unified list - ready to work in seconds.
                            

Supported classifications: Fire Protection Wet, Fire Protection Dry, Fire Protection Pre-Action, Fire Protection Other

Configure Rules

Set spacing, clearances, and hanger families per pipe size

Define placement rules for each pipe diameter using an easy-to-edit CSV file. For each pipe size, you can specify:

Distance from Start/End - How far from fittings to place first/last hanger
Minimum Distance - Minimum spacing between hangers
Maximum Distance - Maximum allowed spacing (code-compliant)
Iteration Step - Precision for clash-free position search
Clearance Distance - Safety zone around each hanger
Hanger Family - Which Revit family to use
Parameter Names - For automatic diameter and rod length assignment

Note: Pre-configured templates available for NFPA 13, MSS SP-69, and other standards

Click Start

Application analyzes pipe runs and extracts placement candidates

The Start button analyzes your selected systems and extracts all pipe runs. During this phase, the application:

Identifies continuous pipe segments (runs) between fittings
Calculates run lengths and directions
Filters out vertical pipes (no hangers needed)
Groups runs by system for organized processing
Displays total run count and pipe count in the status panel

Note: This is a read-only operation - no elements are created or modified yet

Click Insert

Hangers are placed automatically with clash detection

The Insert button performs the actual hanger placement with intelligent positioning. For each run:

Start Position - Finds clash-free point near the beginning
End Position - Finds clash-free point near the end
Interior Positions - Fills the gap respecting max spacing rules

Clash Detection checks for:

Pipe fittings (tees, elbows, reducers, flanges)
Valves and accessories
Other hangers already placed
Structural elements in the path

Automatic Parameter Assignment:

Sets pipe diameter on hanger family
Calculates and sets rod length to nearest floor/beam above
Rotates hanger to align with pipe direction

Real-time Progress:

Progress bar shows current run being processed
Live log file updates on your desktop
Final summary shows total hangers placed and any issues found

📋 Full Transparency

Comprehensive Real-Time Logging

Know exactly what happened, where, and why. Every decision documented.

What Gets Logged

✅
Every Placement
Pipe ID, position, hanger family used, rod length calculated
🔄
Iteration Steps
When clash detected, each step is logged until clear position found. Step size is user-configurable (default: 10mm)
🛡️
Clashes Avoided
What element caused clash (fitting, valve, wall, duct, etc.) and how it was resolved
⏭️
Skipped Pipes
Pipes that couldn't receive hangers and why (too short, no matching rule, vertical, etc.)
📊
Run Statistics
Total pipes processed, hangers placed, clashes detected, time elapsed

Why This Matters

🔍

QA/QC Ready: Auditors can verify every placement decision

🐛

Easy Debugging: If something looks wrong, check the log to see why

📁

Project Documentation: Keep logs as part of project records
