What is DCR?

Design Coordination Rate (DCR) is an A–G grade for design coordination quality, inspired by BER energy labels.

What is it for?

It helps BIM managers, PMs and clients quickly understand design coordination risk at a glance.

Why it matters

Poor coordination = more rework, RFIs, claims and delays. Good coordination reduces risk and cost.

Data source

This prototype uses manual user input only. In the future, we could receive files directly from Navisworks, Solibri or other coordination software, with automatic clash and building classifications.

🚀 Quick Start – How to Calculate Your DCR

Follow these steps to get your Design Coordination Rate:

Export a Navisworks clash report and group clashes by priority (High / Medium / Low).
Count the number of clashes in each priority category.
On the Report tab, choose the building size and type.
Enter the clash numbers – the DCR calculates automatically.
Use the DCR grade and summary in your coordination reports.

💡 Tip: Start with one live project and compare DCR between design stages to track coordination progress.

📐 Calculation Method

The DCR is calculated using weighted clashes, building size/type modifiers and a base A–G threshold scale.

Formula


                Weighted Clashes = (High × 1.0) + (Medium × 0.5) + (Low × 0.2)

                Adjusted Value = Weighted Clashes × Size Modifier × Type Modifier

                Grade = A–G based on Adjusted Value thresholds

Priority Weights

Priority	Weight
HIGH	1.0
MEDIUM	0.5
LOW	0.2

Size Modifiers

Size	Area	Mod
Small	< 6,000 m²	2.0
Medium	6–30k m²	1.0
Large	> 30,000 m²	0.5

Type Modifiers

Type	Mod
Residential	1.3
Commercial	1.0
Industrial	0.5
Healthcare	0.5

DCR Thresholds

Grade	Range	Meaning
A	0–50	Excellent coordination
B	51–100	Good coordination
C	101–200	Moderate risk
D	201–350	Emerging issues
E	351–550	Significant issues
F	551–750	Severe pressure
G	>750	Critical risk
