Have you ever wondered what TC1, TC2 and TC3 means for you? You finally find a section that you love but you do not know how the technical category will affect your build. Well here it is in a nutshell…. Technical Category 1 means that future land damage from liquefaction is unlikely. You can use standard foundations for concrete slabs or timber floors. For TC1 foundations we use a NZS 3604 ring foundation which is the most economical. Most builders base their costs on this type of foundation  Technical Category 2 means that minor to moderate land damage from liquefaction is possible in future significant earthquakes. You can use standard timber piled foundations for houses with lightweight cladding and roofing and suspended timber floors or enhanced concrete foundations such as a waffle slab/Ribraft foundation. These foundations are typically more expensive than a standard foundation. Technical Category 3 means that moderate to significant land damage from liquefaction is possible in future significant earthquakes. Site-specific geotechnical investigation and specific engineering foundation design is required. There is no one-size-fits-all solution for homes in Technical Category 3 (TC3) that require repairs to foundations or need to be rebuilt. Foundations designed for homes in TC3 will be site specific and may involve deep foundation piles. Site-specific geotechnical investigation will identify the best foundation design for your property. It is not uncommon for TC3 foundations to cost upwards of $60,000 or more than your standard foundation. There you have it…. TC1 will have a standard foundation which most prices are based on, TC2 requires a waffle slab which is more expensive than a standard foundation and TC3 requires deep geotechnical investigating and a specially designed foundation for each site which can cost $60,000 or more.
