Large-scale condominium renovations are essential for maintaining building safety and asset value, but various problems can arise from the preparation stage through post-construction. This article systematically explains common trouble cases and countermeasures for management associations and owners.
Why are large-scale condominium renovations necessary?
Large-scale renovation is a planned repair project for common areas, typically carried out every 12 to 16 years. It helps prevent sudden failures in water and drainage systems and elevator stoppages, and it directly contributes to maintaining and improving asset value.
What problems commonly occur during the 【preparation stage】?
Conflicts of opinion within the management association
It is generally best for the renovation committee to consist of about five people. If in-house expertise is insufficient, consider engaging a third-party organization (consultant) as well.
Insufficient repair reserve funds
There are three main ways to address a shortfall.
- Collect a one-time contribution to cover the shortage
- Borrow from a financial institution
- Raise the repair reserve fund amount
The most important preventive measure is the regular review of the long-term repair plan.
What problems commonly occur 【during construction】?
Construction schedule delays
Bad weather and specification changes are the main causes. The key is to hold thorough meetings in advance and keep changes to the work scope to a minimum.
Noise, odors, and dust
It is essential to provide a careful advance explanation to residents and secure their understanding and cooperation.
Burglary incidents
Because scaffolding can create access routes for intruders, security cameras, auxiliary window locks, and standardized worker uniforms are effective countermeasures.
Additional work and increased costs
Some defects only become apparent after scaffolding is erected, so conducting a building inspection in advance can help control unexpected additional costs.
What problems should you watch for 【after construction】?
Differences from the expected finish
Samples should be checked in the actual environment (outdoors and in sunlight), and if possible, a trial application should be carried out.
Recurrence of construction defects
If you choose a contractor based only on low cost, you may face a risk of needing corrective repairs later. Please make your selection only after comprehensively evaluating track record, technical capability, and after-sales support.
What measures help prevent problems before they happen?
- Thorough advance notice to residents and nearby neighbors
- Choose a contractor enrolled in defect insurance (with third-party inspection)
- Select a reliable contractor with extensive experience and careful service
