After the operation instruments staff member entered the result of inspection edited the description in the PDA and provided the updated information to the system see Fig. 7 . Once the instrument was break and need to be repaired the system also can provide the supplier information and handle the problem immediately. Finally the instruments manager and the authorized staff members accessed the updated information from office synchronously. 7. Field tests and results Overall the field test results indicate that UHF passive RFID tags are effective tools for instruments maintenance management in construction lab. All tags survived use in the instruments environment over one month testing period. The number of instruments for inspection and maintenance progress in field trials was around fifty. The M-RFIDMM system was installed on main server in the instruments management division of the construction lab. During the field trials verification and validation tests were performed to evaluate the system. The verification aims to evaluate whether the system operates correctly according to the design and specification and validation evaluates the usefulness of the system. The verification test was carried out by checking whether the M-RFIDMM system can perform tasks as specified in the system analysis and design. The validation test was undertaken by asking selected case participators to use the system and provide feedback by answering a questionnaire. The case participators consisted of two maintenance managers with 6 years of experience six maintenance staff members with 5 years of experience above in the case study. To evaluate system function and the level of system capability satisfaction we distributed questionnaires and the users of the system were asked to grade the conditions of system testing system function and system capability separately compared with the typical paper-based
