Earthquake Repair Engineering in Christchurch
Structural assessment, repair design and engineering support for earthquake damaged residential and commercial buildings.
Request an Initial ReviewEngineering Support for Earthquake Damaged Buildings
Earthquake damage can affect foundations, floor levels, structural connections, walls, framing and other parts of a building. Some damage is visible, while other issues may require measurements, document review or further investigation.
Landmark Consultants provides earthquake repair engineering services for residential, commercial and industrial properties across Christchurch and Canterbury. Our role is to assess the available evidence, identify relevant structural concerns and develop an appropriate repair strategy.
Depending on the project, our work may include a structural assessment, review of previous reports, foundation level information, repair design, structural drawings, engineering documentation and construction monitoring.
We work with property owners, architects, builders and other project professionals to help move the repair process from investigation through to an achievable construction solution.

Earthquake Repair Engineering Services
The required service depends on the type of building, the available records and the nature of the damage.
Structural Damage Assessment
Inspection of accessible structural elements and review of visible damage, cracking, deformation and other signs of building movement.
The assessment scope can also include available plans, previous engineering reports and repair documentation.
Foundation Assessment
Review of foundation damage, floor level variation, settlement indicators and available relevelling information.
Geotechnical input or additional investigation may be recommended where ground performance is relevant.
Structural Repair Design
Engineering calculations, details and drawings for repair work affecting foundations, framing, structural connections and other load-bearing elements.
Repair solutions are developed according to the confirmed scope and the available building information.
Foundation Repair Design
Engineering input for foundation repair, relevelling, local strengthening and replacement of damaged elements where appropriate.
The repair approach depends on the foundation type, observed damage, site conditions and project requirements.
Repair Documentation
Preparation of structural drawings, repair details, calculations and supporting documentation appropriate to the agreed engineering scope.
Building consent and producer statement requirements are considered where they apply to the proposed work.
Construction Monitoring
Engineering site observations during selected stages of the repair work.
The monitoring scope is agreed before construction and is based on the repair design and project requirements.
When to Request an Earthquake Damage Assessment
An engineering assessment may be appropriate when you have concerns about damage, previous repair work or changes in the condition of a property.
Common reasons for requesting an assessment include:
- New or changing cracks in walls, floors or foundations
- Uneven floors or changes in recorded floor levels
- Doors or windows that no longer operate correctly
- Visible movement or separation between building elements
- Concerns about previous earthquake repairs
- Missing or incomplete engineering documentation
- Proposed renovation or alteration of a repaired building
- Questions raised during a property purchase
- A request for further information from another project professional
These signs do not automatically confirm serious structural damage. An assessment helps place the observations in the context of the building, foundation and site.
Our Earthquake Repair Process
A structured process from document review through to repair completion.
1. Information Review
We review the property address, photographs, plans, previous reports, repair scopes and other available documentation.
2. Site Assessment
An engineer inspects the accessible areas relevant to the agreed scope and records visible structural conditions.
3. Repair Design
Where repair work is required, we develop the engineering solution and prepare the agreed calculations, details and drawings.
4. Construction Support
We respond to relevant technical queries and provide construction monitoring at the agreed project stages.
What Earthquake Repair Design May Address
The design scope depends on the type and extent of damage. Repair engineering may address:
- Cracked or damaged concrete foundations
- Foundation settlement and floor level variation
- Damaged timber framing and structural connections
- Damaged steel or concrete structural elements
- Localised wall and bracing damage
- Connections between floors, walls and foundations
- Structural effects of previous or proposed alterations
- Repair access and construction sequencing
- Coordination with architectural and building work
Repair Is Different from Strengthening
Earthquake repair and seismic strengthening are related, but they are not the same service.
Earthquake repair generally addresses identified damage and aims to restore the affected structural elements according to the agreed repair objective.
Seismic strengthening involves upgrading an existing building to improve its expected performance in future earthquakes. Strengthening may involve a wider review of the structural system and additional design work.
The appropriate approach depends on the building, the damage, the required outcome and any applicable regulatory or project requirements.
Learn About Seismic StrengtheningChristchurch Earthquake Repair Considerations
Earthquake repair projects in Christchurch often involve more than visible cracking. The assessment may need to consider foundation performance, recorded floor levels, previous repair work and the relationship between the building and the ground.
Available records can be important. These may include previous engineering reports, repair strategies, building consent documents, construction photographs, inspection records and producer statements.
Where documentation is incomplete or structural elements are concealed, further investigation may be required before an appropriate repair solution can be confirmed.
Landmark Consultants can coordinate structural and geotechnical input where the foundation and ground conditions need to be considered together.

Earthquake Repair Questions
General information for Christchurch property owners.
Do all cracks indicate earthquake damage?
No. Cracking can result from several causes, including material shrinkage, moisture changes, settlement, construction details and structural movement. An assessment considers the crack pattern together with other available evidence.
Can you review previous earthquake repairs?
Yes. We can review accessible building areas and available repair documentation within an agreed scope. Additional investigation may be needed where work is concealed or records are incomplete.
Do you carry out the building repairs?
Landmark Consultants provides engineering assessment, repair design, documentation and construction monitoring. Physical construction work is completed by an appropriately engaged building contractor.
What information should I provide?
Send the property address, photographs, a description of the concern and any available plans, repair reports, consent documents, foundation information or inspection records.
Is building consent required for earthquake repairs?
Consent requirements depend on the proposed work and the circumstances of the project. The repair scope should be reviewed before confirming the required approval and documentation pathway.
Can you monitor the repair work?
Yes. Construction monitoring can be included for agreed stages of the structural work. The required inspections should be confirmed before construction begins.
