Optimized and consolidated Admin Management whose particular functions have a strong connection to the Construction Industry, includes not only daily requests like stationery or company vehicle application, but also insurance, services, dormitory management and authority offences. Insurance is composed of medical insurance and fire insurance for workers and their dormitory, as well as project insurance and MAR insurance. Based on the critical date of insurance or services, later will be triggered to inform related personnel, which is a desirable model for the construction industry as there is always machinery and equipment involved in a construction project. Dormitory management includes tenancy agreement with both owner and tenant, which would bring a regulated file record for dormitory contract management. By placing all the dormitory and item information in the system, users can now track all the accommodation records, utility records and item change records simply and effectively.
