Case Study on the Maintenance of a Construction Monitoring Using USN-Based Data Acquisition

Table 2

The comparison between CSD and IMS.

	CSD	IMS
Strength	(i) Simple system configuration; (ii) Possibility to develop an installation program and web program	(i) As operated on the web base, monitoring check is possible anywhere with Internet connection; (ii) Possible to process data in diverse formats such as report and graphs; (iii) Possible to set user authority; (iv) Possible to customize programs according to specific on-site conditions
Weakness	(i) Program use faded down; (ii) Slow loading speed when data accumulation is huge	System installation is costly
