PROBLEM TO BE SOLVED: To correct work schedule based on a result of work.;SOLUTION: A management device 10 receives a work result transmitted from a portable terminal 20 (step S18), and analyzes the content of the received work result, and stores the work result in a construction work information DB part 12 (step S19). When a result of construction is input as a work result, a work achievement rate is input. When a result of inspection is input, a work achievement rate is calculated. The work achievement rate is automatically calculated by dividing the number of the input inspection results by the total number of inspection objects, and dividing the number of inspected drawings by the number of drawings necessary for inspection or the like. A management device compares a work start date, work end date and period of a planning stage and the work achievement rate of an actual work stored in an inspection information table, and forms a new schedule for the current work (step S20). Thus, it is possible to automatically correct the schedule by reflecting the work result.;COPYRIGHT: (C)2011,JPO&INPIT
