FLOOD DAMAGE
Dealing with flood and stormdamaged buildings In a natural disaster, Civil Defence conducts rapid building assessments and issues stickers to identify buildings that have been damaged and those that present a severe safety risk. The sticker's colour indicates what access you can have to the building. Red Sticker
Follow-up assessment
A red sticker means no one is allowed to enter the building because of the high level of risk. This risk might be the building itself, but it DO NOT REMOVE THIS NOTICE might also be from nearby buildings or unstable land. A builder who wants to assess the site for remedial action will need special clearance from the local council.
Initial assessments carried out by Civil Defence are rapid – taking about 20 minutes – and can sometimes be completed by inspectors from outside the building without needing to enter.

Insurance companies often have "preferred suppliers" and may direct the homeowner to use tradespeople, designers and geo-tech engineers on their "preferred" list.

After the rapid assessment process, Civil Defence emergency management and council officials can direct the owner of a building to obtain a detailed assessment of the building. These assessments are the responsibility of a building owner and will usually involve input from the owner's insurance company.
You will need to coordinate any visit with the owners, the council and the insurance company, which will require a detailed quote for any remedial work required.
If you are assessing a damaged building or plan to do remedial work, you must take all possible measures to safeguard yourself and your team. While SiteSafe has rules and guidelines for work site safety, there are some additional steps you should take when dealing with flood and storm-damaged buildings.
