Special Character

  • Riverbend Bible Church

    Brief

    To provide geotechnical, structural, civil and fire engineering design as part of a design team from feasibility and concept through to construction completion.

    Project Outline

    This architecturally designed upgrade of the existing multi-use building, incorporated a new ablutions block and enclosed walkway linking the two facilities. The project included stormwater design, new foundations, steel frames, masonry and timber walls, as well as demolition and strengthening of existing brick walls.

    Challenges

    The geotechnical report indicated the site had geotechnical challenges which required upgraded foundation solutions including foundation ties and rafting.

    We were required to create a structural design that met the client’s criteria, while  minimally disrupting the interior of the multi-use building. This was achieved by applying strengthening to the exterior using buttressing structures for strengthening and structural framing of additional walkways and utility rooms.

    We also had to design on-site stormwater disposal solutions.

     

  • Maryknoll Chapel

    Brief

    To provide geotechnical, structural and fire engineering design from feasibility and concept through to the completion of construction.

    Project Outline

    The project involved an upgrade of the existing monastery accommodation block and construction of a new chapel. The development also included the upgrade of the accessway.

    Challenges

    The new chapel was a challenging structure, utilising curved glue-laminated timber rafters to form a dome on a sloping site.

  • Karamu High School Sculpture

    Brief

    To provide structural design from feasibility and concept through to the completion of construction.

    Project Outline

    The project involved foundation and super-structure design of a complex steel sculpture.

    Challenges

    The complexity of the structure required a combination of design modelling and on-site verification during fabrication.

    Outcome

    This work resulted in an aesthetically pleasing sculpture and a very satisfied client.

  • Hastings Courthouse Sculpture

    Brief

    To provide structural design from feasibility and concept through to completion of construction.

    Project Outline

    The project involved foundation and super-structure design of a complex steel sculpture.

    Challenges

    The complexity of the structure required a combination of design modelling and on-site verification during fabrication.

  • Greenmeadows New World Sculpture

    Brief

    To provide a structural design from feasibility and concept through to the completion of construction.

    Project Outline

    To design a metallic tree sculpture to be placed in the Greenmeadows New World carpark. The structure was 6m high and each leaf was different.

    Challenges

    Due to the unique structural form of the sculpture, the design was based on a series of prototypes which were fabricated and tested before finalising the design.

    Outcome

    The project was completed on time and on budget and is now an iconic feature of the supermarket.

Efficient Seismic Design of 3D Asymmetric and Setback RC Frame Buildings for Drift and Strain Limitation.

Congratulations to Philip Wilkinson one of our Senior Structural Engineers. Philip along with his advisor have recently had their paper on ‘Efficient Seismic Design of 3D Asymmetric and Setback RC Frame Buildings for Drift and Strain Limitation’ published in the Journal of Structural Engineering.

  • Abstract:  “This paper presents an analysis–redesign-type approach for the efficient seismic design of three-dimensional (3D) irregular RC frame structures for bidirectional ground motions. The designs obtained using the approach satisfy interstory drift and ductility limits while having the minimum total moment capacity of all seismic members. This leads to cost-efficient designs because the total amount of steel as well as the base shear and overturning moments are relatively low. While doing that, the approach is very intuitive and is relatively simple to implement in practice because it only requires analysis tools, not background knowledge or tools related to optimization theory. The examples show that the proposed methodology requires only a few analyses and converges to designs that exactly satisfy the design objectives with limited amounts of steel assigned only where required. This makes the design approach feasible for practice in terms of computational effort and time.”
