Half of the pitfalls in renovation lie in the construction site: wrong sequence, poor workmanship, and perfunctory acceptance lead to rework after move-in. This Skill organizes the essence of construction topics from the Xi'an Renovation Classroom knowledge base with relevance priority (essentials first), covering the full chain of demolition and alteration, plumbing and electrical work, tiling, carpentry, painting, waterproofing, concealed works, and acceptance supervision. It is a construction manual you can follow to keep an eye on the site.
Core Principles (Remember These 5 First)
- The sequence cannot be messed up: demolition and alteration -> plumbing and electrical -> tiling -> carpentry -> painting. If the previous step is not done well, everything later will be reworked.
- Concealed works are the top priority: plumbing and electrical routing, waterproofing, pressure testing, and water-ponding tests must be accepted before sealing.
- For plumbing and electrical, do the briefing before cutting grooves: point locations, whether to route overhead or on the floor, load-bearing wall regulations should be decided in advance, not improvised on site.
- Tiling and painting depend on details: hollow tiles, leveling, number of putty coats, and painting workmanship directly affect the appearance.
- Acceptance must keep evidence: photograph each milestone, pressure test records, and water-ponding tests, so there is a basis if problems arise.

How to use
When users ask renovation-related questions (regardless of whether construction has already started), first locate the reference files according to the topics above, then give advice based on the specific layout/budget. Key points:
- Give conclusions directly: first say "what not to do," then say "what to do."
- When it involves modifications (knocking down walls, changing doors, changing drainage), be sure to remind them to first confirm whether it is a non-load-bearing wall, property management policies, and the waterproofing scope.
- When safety is involved (electricity use, slip resistance, child safety), use a self-check list format so users can check accordingly.
- Don't remove the AI flavor; use the "everyday life" tone of Xi'an Renovation Classroom, speak plainly, and provide useful干货.
