Creating detailed plans and specifications for buildings or structures using various materials, such as cross-laminated timber (CLT), steel, masonry and concrete.

 

Project example: The Big Cottage.

Developing residential foundation design for buildings on land with technical classification 1, 2 and 3, (TC1, TC2, TC3) and land adjacent to or within mass movement sites.

 

Project example: The Big Cottage

Developing designs for commercial and industrial structures, incorporating specific construction methods like portal frame or tilt-panel construction.

 

Project examples: Hagley Window & Doors and Taylors Mistake Surf Lifesaving Club

Structural elements of residential buildings, for both flat and sloping terrains, to support architectural designed houses. This includes design of foundations and integrating retaining wall structures.

Conducting assessments and providing reports for insurance or pre-purchase purposes to confirm the structural condition and identifying defects which may pose a potential risk associated with commercial or industrial buildings.

The assessment of the seismic strength of existing commercial and industrial buildings and developing designs to improve seismic resistance of buildings. We also provide initial and detailed seismic assessments to determine the percentage of new building standard.

 

Project example: Opzeeland

Assessing structural damage in commercial and industrial buildings and developing plans for remedial works to restore and strengthen the structures.

 

Project example: Opzeeland

Design of retaining wall structures that support earthworks, buildings and roads often used in developing building platforms on sloping sites.

Structural engineers provide designs for load supporting elements to account for wind, earthquake loading and ground conditions specific to your site. These designs comply with the current New Zealand Building Code and support applications for Building Consent with your local council. Structural engineers also provide support during the construction process by responding to questions from your builder, inspecting the construction as works progress and providing sign-off at completion to confirm the work is in accordance with the structurally designed details.

To ensure precise designs, we require architectural plans for your proposed building or alterations, along with geotechnical reports and a detailed scope of work outlining your project requirements. Providing this information will allow us to deliver tailored and effective solutions for your needs.

Yes. Our structural engineers provide tailored advice on suitable foundation options based on site conditions, load requirements, and local regulations.

Yes. We can complete both Initial Seismic Assessments (ISAs) and Detailed Seismic Assessments (DSAs) on low rise commercial properties, as well as providing advice and designs for seismic strengthening if it should be required.

Yes, we have an extensive track record of performing assessments for homeowners, insurers, and EQC following seismic events. Our work includes inspections, evaluating damange, detailed reporting, peer reviews, expert evidence preparation, and active participation in mediation and facilitation processes.

We offer thorough assessments of existing structures to determine their seismic resilience and can develop retrofitting and strengthening designs to enhance the seismic performance of structures, for compliance with current standards.

Our structural team specialises in a comprehensive range of residential designs, encompassing new builds, house extensions, and alterations. Below are just a few examples, as structural engineers may be involved in a wide range of residential projects to ensure the safety, stability, and compliance of the structures. 

  • New home construction 
  • Home additions and extensions 
  • Remodelling and renovations 
  • Foundation design 
  • Retaining walls 
  • Seismic retrofitting 
  • Architecturally designed homes

Yes. We can provide you with a comprehensive assessment for retaining wall design by considering factors such as soil conditions, slope stability, and drainage to create structurally sound solutions. As a multidisciplinary company, we work closely with both geotechnical and civil engineers so you have the best advice to suit your needs.
