How to Choose a Safe Demolition Contractor
When dealing with a demolition site, skipping a thorough pre-assessment of the structure's condition can lead to serious safety incidents, so strict adherence to standards is crucial. In this post, we're breaking down all the essential things you need to check, from signing the contract to handling the debris.
What Licenses and Qualifications to Check Before Hiring a Demolition Company
When you're handing over your site, you absolutely must verify if the company is properly registered for construction and what equipment they own. Be warned: if you hire an unlicensed contractor, you, as the property owner, could be held civilly or criminally liable if a workplace accident happens.
You can check if they hold a license for Interior Finishing Construction or a Demolition Construction permit by looking it up through your local government office or the Construction Industry Information System. It's also a good idea to put a specific clause in your contract stating that the site manager has the relevant national technical certifications and will be physically present on site.
How to Assess Structural Safety and Identify Non-Load-Bearing Walls
If you tear down walls without proper assessment, you can negatively affect how the building supports its weight, which might lead to cracks or sinking. According to building codes, you need to confirm beforehand, using the structural blueprints, whether a wall is a non-load-bearing wall that doesn't carry weight.
- Obtain and compare the building register and structural drawings.
- Inspect the slab thickness and rebar in the beams during a site visit.
- Confirm approval from the property management office or a structural engineer.
Comparing Timeline and Average Costs by Demolition Type
The way the work is done and how many people are needed changes based on the site conditions and size, and this directly impacts the quote you receive.
| Type of Work | Average Time Needed | Avg. Cost Per Pyeong | Debris Removal Included? |
|---|---|---|---|
| Interior Renovation | 2 to 3 days | 120,000 KRW | Calculated separately |
| Commercial Demolition | 3 to 5 days | 150,000 KRW | Yes |
| Partial Structure Removal | 1 day | 200,000 KRW | Calculated separately |
When you get a quote, make sure you confirm if the total amount includes the cost of debris removal. Disputes often pop up later when extra disposal fees are added.
How to Handle Debris and Register with the Allbaro System
Any waste generated on-site must be collected and transported according to proper procedures, and you need to get a processing confirmation through the Allbaro System, which is run by the Ministry of Environment.
- Sort the waste according to its type at the demolition site.
- Move the waste to an intermediate disposal facility using a licensed collection and transportation company.
- Generate and keep the electronic information record in the Allbaro System.
- Submit the final completion report to the local government authority.
If the disposal isn't done legally, it can be considered illegal dumping, and the property owner could face fines. To keep disposal costs down, you need to be extremely thorough when sorting large debris by type.
Frequently Asked Questions About Hiring a Demolition Company
What happens if the waste disposal cost is missing from the contract?
If the estimate doesn't list the waste disposal fee separately, you're likely to be hit with extra charges mid-project. You absolutely must include the cost for waste collection, transportation, and final disposal in your contract as a specific clause.
Who is responsible for dealing with neighbor complaints?
For noise and vibration complaints from neighbors, the demolition company hired to do the work is fundamentally responsible for managing the site and responding to them. It’s a good idea to specify in the contract that they are responsible for things like installing sound barriers or adhering to work schedules.
What's the difference between interior demolition and restoration work?
Restoration means returning the property to its original condition as it was when you signed the lease, which can include fixing things like floor tiles or ceiling tiles. Because the scope is broader than just tearing down interior finishes, prior discussion is essential.
Before any site measurement happens, make sure you document any potential extra costs clearly via text message to prevent extreme situations like work stoppages later on.
