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

Table 1

Comparison between existing monitoring and automated monitoring system.

	Automated monitoring	Existing monitoring
Advantages	(i) High precision; (ii) Enable to control various frequencies of monitoring; (iii) Economy of time for monitoring analysis to immediately response; (iv) Many field experimental machines work at the same time; (v) Enable to output the data with monitoring; (vi) Saving the manpower	(i) Economy of time for installation; (ii) Enable to analyze monitoring in the construction site; (iii) Easy maintenance
Disadvantages	(i) Expensive material cost; (ii) Time consuming to install the automatic system; (iii) Requiring field observation	(i) High manpower consumption; (ii) Low precision; (iii) Level of difficulty depends on the field condition; (iv) Time consuming for data analyzing; (v) Unavailable measurements in terms of bad weather
