The Metrics of BIM – The Manage the Built Environment


As the old saying goes…”you can’t manage what you don’t measure”.

 

 

Here’s the beginning of a list of information requirements spanning various domains/competencies, technologies, etc.,
While an important component, the 3D component of BIM has been a very unfortunate distraction.  It appears that many/most have “gone to the weeds” and/or are “recreating the wheel” vs. working on core foundational needs such as the consistent use of appropriate terminology and the establishment of robust, scalable and repeatable business practices, methodologies, standards, metrics and benchmarks for facilities and physical infrastructure management.

It is common terminology that enables effective communication and transparency among the various decision makers, building managers, operators and technicians involved with facilities and physical infrastructure investment and management.

Here are examples of metrics associated with the life-cycle management of the built environment:

Annualized Total Cost of Ownership (TCO) per building per gross area = Rate per square foot

Annualized TCO per building/Current replacement value = Percent of Current Replacement Value (CRV)

Annualized TCO per building/Net assignable square feet = Cost rate per net assignable square feet per building

Annualized TCO per building/Non-assignable square feet = Cost rate per non-assignable square feet per building

Annualized TCO per building/Building Interior square feet = Cost rate per interior square foot per building

Churn Rate

Utilization Rate

AI (Adaptation Index) or PI (Programmatic Index) = PR (Program Requirements) /
CRV (Current Replacement Value)

Uptime or Downtime – Defined in percent, as amount of time asset is suitable for the program(s) served.

Facility Operating Gross Square Foot (GSF) Index (SAM Performance Indicator: APPA 2003)

Custodial Costs per square foot

Grounds Keeping Costs per square foot

Energy Costs per square foot

Energy Usage

Utility Costs per square foot

Waste Removal Costs per square foot

Facility Operating Current Replacement Value (CRV) Index (SAM Performance Indicator: APPA 2003)

Planned/Preventive Maintenance Costs per square foot

Emergency Maintenance Costs as a percentage of Annual Operations Expenditures.

Unscheduled/Unplanned Maintenance Costs as a percentage of Annual Operations Expenditures.

Repair costs (man hours and materials) as a percentage of Annual Operations Expenditures

FCI (Facility Condition Index) = DM (Deferred Maintenance) + CR (Capital Renewal)
/ CRV (Current Replacement Value)

Recapitalization Rate, Reinvestment Rate

Deferred Maintenance Backlog

Facilities Deterioration Rate

FCI (Facility Condition Index) = DM (Deferred Maintenance) + CR (Capital Renewal) /
CRV (Current Replacement Value)

AI (Adaptive Index) or PI (Programmatic Index) = PR (Program Requirements) /
CRV (Current Replacement Value)

FQI (Facility Quality Index) or Quality Index or Index = FCI (Facility Condition Index)+ AI (Adaptive Index)
