| Abstract | The problems regarding to sustainable construction are that the most of construction materials are considered to be low efficiently used. The less efficient use of construction materials will not be a problem if the natural resources are limitless, but in fact it is not. In addition, the construction firms need to be reminded that waste make fina ncial cost both direct cost and indirect cost are significant. Many researches have tried to apply the 3Rs (Reduce, reuse, and recycle) waste strategy for mana ging waste on construction sites. Consequently, this study has tried to a pply the concept of 4Rs, reduce, reuse, recycle, residual management concept in Thai building construction industry. To apply 4Rs, reduce, reuse, recycle, residual management concept in Thai construction industry is the main purpose of this thesis. In order to correlate the main and the sub-objectives of th is study, research methodology has been split into three main st eps. The first step is to investigate existing 4Rs-relevant activities. The result is that the related activities following 4Rs concept. These activities would be utilized in the next step, gathering the significance and applicability of collected 4Rs-relevant activities. The second step, some activities have been removed. There are six experts utilized in the second step. The last step is to measur e the application of each 4Rs activity on sites at both management and operationa l level. The data in last step were collected from both Bovis Lend Lease (Tha iland) Limited and other companies within Thai building construction industry. The results were found that validated ei ght general issues can be implemented through the 4R’s concept. Moreover, there are eight groups of work which 4Rs concepts can be implemented through that are improvement of material ordering and supplying, changes of material select ion, improvement of site material management, increase of work controlling, defining of alternative options for reuse and recycle, provision of sorti ng methods and container, area, or infrastructure for collection of by-product, and setting of policie s according to the relevance law and regulation. |
