Developing Mobile BIM/2D Barcode-Based Automated Facility Management System

Table 2

Comparison of current approach and proposed system.

Item	Current approach		Proposed approach
	Method	Average time	Method	Average time
Edit the defect problems of the facility	Edit the defect problems by paper-based sheet	12–20 sec	Edit the defect problems through the BIMFM system	6–12 sec
Find basic information on facility for reference	Review maintenance data on paper-based sheet	12–23 sec	Access basic information on a facility directly by accessing and clicking BIM model	7–13 sec
Refer to relevant historical maintenance information	Refer to paper-based maintenance lists and reports	12–18 sec	Click BIM model and refer to historical maintenance information directly	6–12 sec
Maintenance information updating	Identify and record results on a checklist, then re-enter at the office	42–52 sec	Real-time data entry in the system during maintenance process	22–42 sec
Mark the inspection problems at the facility location	Refer the paper-based maintenance condition and status sheet	1–1.5 min	Illustrate overall maintenance conditions and status of FM quickly through visualized BIM model	40–50 sec
