Project 5: Develop a BIM-based plug-in application using Revit-API to automatically measure core KPIs using the embedded data and user inputs.

Facility Performance Measurement using Key Performance Indicator:

§Condition index (CI)

    A condition index reflects the physical condition of a system or facility.

    CI=  (Maintenance deficiency)/(Current replacement value)=  DM/CRV

§Maintenance efficiency indicator (MEI)

    This indicator reflects the maintenance performance of a facility

     MEI=  SDM/CI×100

     SDM=  (DM (Actual))/(DM (Targeted))  ×100

§Replacement efficiency indicator (REI)

    This indicator reflects the replacement efficiency of a facility.

     REI=  (∑1▒〖Cap.R〗)/(∑1▒〖Exp.〗)  ×100

§Functional index (FI)

    This indicator reflects the suitability of a facility for the intended use.

FI=  (Total area of specific space type ( Actual) )/(Total area of specific space type (Required))

Building Information Modeling in Facility Management:

BIM in FM à Extracting information for the purpose of operation and maintenance activities. 

§The application has three phases:

§First Phase: Extract geometric data from the BIM model à Areas 

§Second Phase : Extract cost data from the Spreadsheet à created by facility managers 

§Third Phase :  based on the mathematical expression of KPIs as well as correlations between them to calculate each KPI and generate values as an output. 

§Expectation

This application enables facility managers (with no expertise in Revit) to benefit form automation and having access to real – time data in an efficient manner.
