The purposes of this study was to investigate accuracy and indigenity of landscape plant species in planting design and construction at housing complex and offer basic data for improving precision of planting construction. The scientific name of landscape plant species was described in planting drawings at only two sites among twelve survey sites. According to analysis on indigenity of plant species in planting drawings, it was found that the component ratio of foreign species was the highest and the component ratio of native species at public housing complex was the lowest. The component ratio of landscape plant species in planting construction was severely differed to that of planting drawings. Also the component ratio of cultivar was higher than that of planting drawings due to planting of sevveral cultivars for one species in planting drawings. In the result of accuracy analysis on landscape plant species in planting construction, it was found that mean ratio of inacccurate species was 33.2% at public housing complex, 29.6% at local company housing complex and 26.4% at nationwide company housing complex. It was found that several cultivars were planted for one species in planting drawings. The representative species which were planted by several cultivars were Camellia japonica, Rododendron spp., Prunus spp. and Magnolia spp. and so on. In order to promote the precision and speciality of planting design and construction, scientific and cultivar name of plants should be described in planting drawings.

This paper presents eco-friendly planting method to overcome the problems of existing concrete retaining wall and gabion retaining wall, respectively, based on the examination on existing concrete and gabion retaining wall. Prior to doing this, proper design method was provided through pull out test. Planting method using gabion metal net and L shape green net retaining wall were compared and analyzed. According to this study, it is confirmed that reduction of construction period and economical profit in construction can be achieved by both manufacturing at the factory and self procurement at the job site as well as the use of metal net, which is applied as a substitution of existing strengthening material. For the effect of planting method, the use of L shape green net retaining wall shows superiority to environment-friendly gabion retaining wall in its ability to rootage and germination of the grass. The L shape green net retaining wall had excellent performance in helping rootage of grass and prevention of soil leakage, and even if raining period, remarkable damage of planting mat does not occur when planting mat is applied.

The purpose of this study is to compare and analyze how many species of trees presented with scientific names are on the written test for engineer landscape architecture, as their usage has increased in the landscape industry in recent years. The following is the result of comparing and analyzing the species of trees which are frequently used in landscape, planting construction, and the scientific name questions presented in the previous 6 years by year on the written test for engineer landscape architecture. First, the results of analyzing the examination question frequency by year in the landscape planting subject showed a gradually declining trend from 2014 after peaking at 56.6% in 2013. Second, 163 species of trees using scientific names were presented in questions on the written test for engineer landscape architecture over the previous 6 years and these included Betula platyphylla, Sophora japonica, Cercis chinensis, Taxus cuspidata. The number of species of trees used in landscape construction during the same period was 169 including Pinus densiflora, Chionanthus retusus, Cornus officinalis, Syringa dilatata. The result of interviews with landscape planting construction officials showed that when choosing the species of trees, they emphasize ecological characteristics, such as the ratio of trees to shrubs, flowers and autumn leaf characteristics, and also consider the morphological characteristics, landscape characteristics, economic feasibility, and the supply and demand situation. Third, it was found that 70 (42.9%) out of 163 species of trees presented with scientific names on the examination were not used in landscape planting construction and 76 (44.9%) out of 169 species were not used as material for questions. As for the scientific name questions, deciduous trees and evergreen shrubs accounted for the more questions, Evergreen and deciduous tree and shrubs were most common in landscape planting construction as well.

This study analyzes the validity of the type classification of the type and design changes of apartment landscaping planting construction design changes that were completed in the private sector, efficiently manages the design changes that are displayed over landscaping planting work in general in the future, and performs research by placing the object underlying the presentation. The results are as follows. First, the percentage that occurred in the planting construction of design changes that have occurred in the apartment landscaping construction was carried out in the private sector and accounted for 61.8%. This indicates that part of the planting is a major design change. Second, as the cause of such a design change to be those associated with the field conditions such as lack of main construction period. In particular, due to a change in oral, appeared 7-48 times design changes of one review design change approval is complex, design changes of planting construction had shown a feature that occurs in multiple simultaneous. Third, the 7 types of Design Changes in planting design were delineated as 'design changes for consideration of the user', 'design changes for image improvement', 'design changes for ease of maintenance', 'design changes due to the mismatch of design statement', 'design changes due to the relationship with the engineering species of other', 'design changes due to lack of field study', and 'design changes due to the consideration of feasibility.' Fourth, 'design changes for consideration of the user' and 'design changes for image improvement' were found in more than half of the frequency of the overall changes. This differed from the results shown in public corporations. Fifth, if planting construction design change process, private companies, it was found that is showing the approval of the practice after the previous construction of the construction cost savings due to construction time. However, in the case of a public corporation, these exhibited a different aspect from the private sector and show a design change procedure that reflects the changes after the design change events in the field have occurred. The above results, the type of landscaping works in planting design change of public enterprises, regardless of the private sector, is the same in the seven types, the main reason of and procedures for design changes, indicating that there are other respects. In design change, it may be desirable to apply becomes liquidity rationality and efficiency of the dimension, depending on the nature of the landscape construction.

We divided the planting bale into waterproof layer, drainage layer and soil layer so at to investigate changes of live load according to species of wood and composition of the base to make rooftops green. The results are follows, 1. As concerning construction and live load for green roof, sheet waterproofing is superior. 2. When materials of drainage are changed crushed gravel into artificial lightweight graval or ferrite, live load of planting bale is decreased about 22% and 25% in order. 3. When ingredients of soil are chased normal sand into volcanic sand, live load of base is decreased about 28%. Especially, when it is changed into ferrite, 54% of live load is decreased. 4. In this study, all live load we concerned excesses the standard about roof live load of office, school and house. Hence, structure has to be concerned thoroughly when making rooftops green. But, we judge that various methods for making rooftops green can be applied if we consider roof garden when we plan new buildings.
