CAPITAL HOUSE AUSTRALASIA (CHA) - Brian A Nelson

Brian Nelson is a founding director of CHA (Consulting Civil & Structural Engineers).

Over the past decade, he has researched and applied the use of FRP composites to a range of over 30 varied structural applications, from fine art pieces to bridges. Primary drivers have been the objectives of achieving large scale, high-quality surfaced structures. These have been achieved through radically differing manufacturing approaches. Significantly, many solutions have arisen out of the conversion of projects, originally conceived of orthodox materials, to FRP. 

Technical, commercial and industrial interfacing between designer-engineer-constructor-client have required development of approaches unique to the medium.   

More recently, to further benefit from the many inherent attributes’ and efficiencies that composites offer, projects have centered on taking a mass production approach to manufacturing. 

Cecil Avenue Masterplan Paving Pattern: Design Assist with PLACE Laboratory by Daniel Giuffre

Scope: Design assist, computatational design, shop drawings, visualisation

If/LAB were engaged by PLACE Laboratory in a Design Assist role to develop up and detail paving patterns for their Cecil Avenue Masterplan.

The masterplan proposal includes a unique and eloquent paving pattern that spans approximately 380m along Cecil Ave, from Albany Hwy to beyond Pattie Street. The design intent by PLACE Laboratory was to emulate the effect of water or tides, similar to the way the ocean’s tides interacts with the shore.

We were provided with the overall surface pattern masterplan, a paving sample drawing and pattern details that identified the paving mixes for each zone.

By using computational design tools such as Grasshopper, we were able to extrapolate the information provided to visualise the paving pattern across the entire masterplan. This enabled the designers at PLACE Laboratory to tweak the patterns, by moving the curves that define each of the paving ‘zones’. In addition to refining the overall paving pattern across the site, the custom tool allowed for fine tuning of the paving distributions, with a live feed of quantities for each paving type.

Sketch to Code: Digital Drawing

An interesting challenge was liaising with the designer, to get inside their mind and try to understand what they are thinking, in order to translate their design intuition, into a series of rules that could be coded.

In our initial briefing meeting with PLACE Laboratory, the designer instructed us to distribute the selected paving types randomly. Upon meeting again at the next design review, we quickly worked out that the way they ‘sketched’ out the paving distribution was not entirely random.

‘Although what you think you are doing is random, there is a good chance subconsciously you are applying rules and logic to each and every line you draw.’

When you ask the machine to do something random, it is truly random, when yourself as a designer tries to do something random, random your intuition takes over subconsciously, applying some form of logic to your design.

Deliverables: Output

As part of our deliverables, we were asked to deliver detail layout plans and quantities for Lighting Brick, who are contracted to install the pavers. The grasshopper code allowed for the nominated gap between pavers, with each and every single paver constructed – proving us with an accurate and automated material takeoffs, which would otherwise have been guesswork.

 A suite of drawing and layout tools developed in-house was used to automate the production of the drawings, which consisted of 32 detail plans at 1:50 on A1 Sheets. These drawings will then be used by Lightning Bricks for install.

Visualisation

In addition to assisting PLACE Laboratory in design, and providing the shop drawings for install, the detailed 3D model was used to produce accurate visualisations of the final pattern distribution to share with the clients and stakeholders.

Implementing GIS Workflows for Architectural Visualisation by Daniel Giuffre

Previous Post: GIS meets Architecture - why?

In Western Australia, there is a wealth of geometric data collected on everything from landscape topography, building footprints, road networks to seasonal flood mapping. This powerful repository of data is mostly made available to the public through open data initiatives like data.gov.wa.

At ifLAB we work with GIS data within Architectural modelling environments to assist in both decision making and visualisation processes. Our GIS software of choice, the open source QGIS has some 3D capability, but compared to 3D modelling software, it is not a productive environment to work on new designs. We prefer workflows that utilise each software package for the task it best suited for, so while QGIS is excellent as aligning different types of Data, when it comes to 3D modelling, Rhino is our tool of choice.

An example of how we are using GIS data in practice is generating an accurate topological mesh with a high-resolution texture generative from satellite imagery. When we download satellite imagery, we get the option to download a text file that contains information about its geographical coordinates. We use QGIS to align the image with other datasets we have downloaded from data.gov.wa (for example, topographic contours). This avoids having to convert between mapping projections manually.

Exporting everything as a shape file, we bring the information into Grasshopper with our current GIS Plugin on choice; Meerkat. Meerkat has an interface to trim down shape files to a given area. By setting the area to be larger than the downloaded satellite image, we can get all the information we need without processing data from the entire state and overloading the system.

[Figure 2: Mesh and Aerial Texture overlay

[Figure 2: Mesh and Aerial Texture overlay

Within Grasshopper we make a mesh of the points brought in from the contours, and trim it down to the extent of the satellite image. Using the excellent mapping tools from the Human Plugin, it’s simple work to give the new mesh planar mapping, set to the location and dimensions of the original Satellite Image bounds. Within grasshopper we programmatically make a new material with the original image and bake the mesh with the new material and the correct mapping.

The output is similar to a Google Earth 3D model, only because we control the sources of data we use, we have control over the process, and can use it for modelling the way we would use any other piece of geometry in Rhino. We can also rely on the result to be as accurate as the sources of data that we use.

The end result with other sources of data overlaid becomes a useful tool to see how designs respond to their context, with a range of other applications.

Responsive Lighting with Arduino, Firefly and Grasshopper by Daniel Giuffre

With the advent of technology, the line between the real and the virtual is becoming progressively blurred. We interact with the virtual on a day to day, hour to hour, minute to minute basis -smart phones, software and the web have become a woven and essential part to the way we live.

The Green Bridge concept proposal enabled us to explore basic principles of interaction and communication between the virtual and the physical, which is crucial in realising the possibilities buildings of tomorrow have in responding to their users, to programmatic requirements and to changes in climate throughout any given year.

Our concept proposal for the Green Bridge public artwork in the Gold Coast was the first step in exploring these themes. The video above demonstrates an effort to begin to understand the potential of responsive buildings through exploring one way of interacting with the digital model.

intensive fields lab arduino

The prototype was developed using an Arduino, an open-source micro-controller, with an ultrasonic sensor for measuring distance. The sensor emits an ultrasound which travels through the air, and if it hits an object it will bounce back to the sensor. The distance is then calculated by considering the speed and travel time of the ultrasound.

 The lighting was intended to be actuated through sensors on the bridge, enabling the bridge to interact and communicate with the heart of the cultural centre, HOTA.

As people cross the bridge to enter the precinct, their movement will create effects through the lights. This acts as a beacon that communicates to those already within the cultural centre that people are entering.

Pedestrians and cyclists pass through a gateway threshold as they approach Gold Coast’s Home of the Arts Precinct. The ribbon like structure wraps around the bridge and continues on overhead to create a sense of welcome, identity and presence.

The artwork aims to form a point of arrival as an activated beacon within the precinct, celebrating the views over the lake towards the HOTA site.

Optimisation of Facade Panels for The Crest Apartments by Daniel Giuffre

The adoption of computational design enables smaller teams of designers to compete with the larger practices, by implementing digital workflows into their everyday. This is also true for fabricators who will inevitable find themselves pressured by demands for realising complex geometry and advances in technology.
