In recent years, Taiwan government requires the construction team builds and delivers BIM models in as-built stage, in order to help public sectors utilizing BIM in facility management of public construction. Through the operation of 4 function modules in Archibus system, this research sums up that 5 kinds of information are required by Space Planning & Management function module, 4 kinds of information are required by Asset Management function module, 5 kinds of information are required by Preventive Maintenance function module, and 2 kinds of information are required by Lease Administrator function module. This research compares the different between ＂as-built COBie＂ and Archibus information requirement, and concludes that both of them require ＂Space＂ and ＂Equipment/Furniture/Socket＂ information. The information of ＂Geography＂, ＂Finance＂, ＂Employees and Craftspersons＂, ＂Spare＂, ＂Tool＂, ＂Problems and Solutions＂, ＂Maintenance processes and procedures＂, ＂Time＂ and ＂Leasing contract＂ are required by Archibus, but ＂as-built COBie＂ do not supply them. According to the characteristics of most common processes in information delivery and the conditions of facility management personnel, this research makes ＂B+C transferring process＂ in 5 steps to translate the information from BIM to Archibus. This research uses Da Long Dong Public Housing as a case and transfers its building information from BIM into Archibus database by ＂B+C transferring process＂. Finally, 3 aspects are used to assess the effect about using ＂B+C transferring process＂ to transfer building information into facility management system.
