As indoor landscaping work is an empirical method, the total cost of work is calculated, therefore accidental error arises between the estimated cost of work and execution cost of work. This could cause the quality of work after construction to be low. In addition, it is in actual fact difficult to reflect the work cost according to the characteristic of indoor landscape by using personnel labor cost used in construction and landscaping. There is a necessity to revise the indoor landscaping personnel labor cost for specialization of the business. Accordingly, the type of work of planting work of indoor landscape was analyzed, and the work of seven construction sites where work can be observed and measured for more than three days, were measured and analyzed. As for the work measurement, time research method and work sampling method were used, and 30% of allowance rate was applied. Through the results, the frame work was analyzed as 0.129man/m(mam/M), work of watering off as 0.051man/M, drainage equipment work as 0.046man/M and water supply equipment as 0.074man/M. As for the planting personnel labor cost, according to the disposition and state, plants of 3 'chi' was analyzed as 0.0026-0.009man per each plant, plants of 4 'chi'as 0.0049-0.0035man, plants of 5 'chi' as 0.0104-0.0065man, plants of 6 'chi' as 0.0139-0.0088man, and plants of 7 'chi' as 0.0185-0.0119man. Planting work of indoor landscape plants takes up more than 70% of the total cost of work, therefore, increasing the reliability of work and reducing the competition of excessive cost of work between companies, by accurately calculating the materials and personnel labor cost by type of planting work, is the effect that can be expected. However, the landscape facilities of indoor landscape work or the personnel labor cost standard of equipment works need to be revised in the future. And if new construction methods such as drainage work, water supply work and work of watering off; or materials are introduced, the personnel labor cost has to be promptly calculated.
