Te Whāriki Subdivision
This 350-Lot subdivision in Lincoln required numerous challenges to be addressed during the design and construction phases, and offers residents more than just a home.
When you find large cracks appearing in your walls you know something is wrong. With suburbs expanding outwards, construction over poor soils occurs more often and may result in movement in the structure.
After carrying out geotechnical investigations, floor level surveys, and structural inspections, Fraser Thomas engineers determined that the damage was a result of ground movement caused by the seasonal shrinking and swelling of expansive clay soils.
It was decided that the most cost and time effective solution would be to carry out remedial work on the house to address the symptoms rather than the cause, i.e. provide the house structure with the ability to move without sustaining damage, instead of intensive foundation strengthening that would prevent the movement.
The remedial work involved creating a movement expansion joint across the middle of the house as a pivot point, and then to provide adequate bracing along both sides of the expansion joint.
In order to create as little impact on the house as possible, in regard to aesthetics and function, remedial bracing and expansion brackets utilised slim profiles that could either be hidden within walls, or could potentially become features themselves.
