According to the estimated cost of repair and maintenance of construction works in Appendix VI attached to Circular No. 12/2021/TT-BXD, Chapter I on demolition, dismantling, and cleaning of parts and structures of works, code SA.11800 is to remove lime and old paint (for paint without scraped parts on walls, columns, beams, and ceilings). Mr. Vu Dinh Son (Lai Chau) asked, so can code SA.11811 be applied to scraping on walls, columns, pillars, and SA.11812 to scraping paint on beams, ceilings? If not, which code is correct and appropriate?

The investor and the consulting unit shall base on the above regulations to apply or refer to the promulgated system of norms to determine and manage the construction investment costs for the project.

In case the promulgated norms mentioned above are not suitable for the technical requirements, construction conditions, and construction methods of the project, the investor and the consulting unit shall implement according to the provisions in Clause 4, Article 21 of Decree No. 10/2021/ND-CP dated February 9, 2021 of the Government.
