| dc.description.abstract | Among the urbanized and populated areas, there are more and more problems of construction compounds and remaining soil & stone out of buildings construction, cities renewal or exploitation of public works. For recent years, it becomes more and more serious to the destruction of ecologic environment and city landscape and damage to public safety. Advanced nations are all inclined to recycle, reduce and re-use the sources of secondary products of construction and remaining soil & stone out of constructions. Consequently, we cannot wait to deal with these problems.
No matter government-owned or private agencies, when they develop or build a resource re-use field for remaining soil & stone out of constructions, the first problem they should confront is the selection of base. It will be very difficult once the field is determined. In particular, the land purchase cost at the preliminary period is very high in ratio of development capital. As a result, the advanced evaluation analysis becomes a very significant work. As for the evaluation guidelines of establishing a complete set of construction remaining soil & stone resource re-use field selection, we see from the following points of view:
1. Limits on legal regulation: (1) important water-collecting area, river flowing area, river re-building area, (2) water source preservation area for running water, within specific range, (3) military construction-prohibiting and control items and (4) limits of important facilities within 150M range
2. Analysis on natural environment factors: (1) works land condition, (2) topography terrains, (3) water-collecting area classification, and (4) ecology investigation
3. Analysis on level factors evaluation: (1) social economics and (2) traffic transportation conditions
4. Analysis on economic effectiveness: (1) cost analysis, (2) maximum accumulated cash flow analysis and (3) benefit-cost ratio analysis
We plan from these four aspects. Under the conditions of information booming and network convenience, we dispatch one group of professional engineers to do initial site survey and network data retrieving, and then we operate according to the aforesaid evaluation in order to minimize the risk of applying a construction remaining soil & stone resource re-use field.
In regard to the Hsiu-Li Construction Remaining Soil & Stone Resource Re-Use Field ready for application, we use the evaluation analysis of the initial investment period and investigation preparation as an example to be the investigation items and analysis outcome as simulating to establish a realistic construction remaining soil & stone resource re-use field, and we offer these reference data to decision-makers in order to reduce risk. In addition, we establish a lab in construction remaining soil & stone resource re-use filed. In the lab, we do sieving analysis test, liquid plastic test and specific gravity test. Therefore, we can transfer the soil classification standard by Department of Construction into uniform soil classification standard to effectively classify soil & stone and fully re-use the remaining soil & stone out of construction. | en_US |
