WHL-01DS19
保留／修复／更换
整屋- 适合
- Sound construction with surface damage — the fault is cosmetic, not structural.
- 注意
- Repair reveals its own scope once opened; budget for a finding, not just the visible fault.
- 成本影响
- Lower than replacement, but less predictable.
- 范围影响
- Needs a hold point after opening up, so the decision can change on evidence.
- 负责方
- 由 ELS 统筹
- 适合
- Improving something that works — better performance without full replacement.
- 注意
- The temptation is to upgrade what is visible rather than what fails; check the reasoning.
- 成本影响
- Between repair and replace.
- 范围影响
- Confirm the upgrade is compatible with what is retained around it.
- 负责方
- 由 ELS 统筹
- 适合
- Where the element has failed or will fail within the life of the renovation.
- 注意
- Replacement pulls in the adjoining trades — you rarely replace one thing on its own.
- 成本影响
- The highest of the four.
- 范围影响
- Sequencing matters: identify which trades follow, and in what order.
