Abstract
This dissertation grew out of the question of whether the traditional approach
to on-site landscape design, as practiced into the 19th century, could experience
a renaissance through the use of modern digital tools and autonomous machines
for earthmoving. While research on autonomous excavators is moving toward
market readiness, there are a few design methods and tools in landscape architecture
that address the potential of on-site digital landscape modeling and
robotic execution. To address this gap, this work developed several digital tools
for designing on and with the site, refined them over several case studies, and
finally tested them with a robotically fabricated topographic prototype.
The work is based on the premises that on-site design strengthens the sitespecificity
of the outcome, that design with a digital, three-dimensional model is
superior to current two-dimensional design methods, and that on-site landscape
design requires new, contemporary tools. After analyzing historical precedents
and building on state-of-the-art modeling and visualization methods, as well as
integrating pointcloud technology and satellite-based geolocation, three distinct
digital design tools were developed: A drawing stick for recording geolocated design
inputs directly in the field, a virtual reality application that simulates the
functionality of the drawing stick in a full-scale virtual point cloud environment,
and an augmented reality application that enables the creation, modification,
and visualization of digital models in the field.
The use of the tools during the case studies that were undertaken throughout
this work revealed their potential for precisely interconnecting site, digital model,
and design inputs. While the tools allowed for the direct transfer of design
inputs recorded on site into a digital model, the subsequent use of an autonomous
excavator to translate a digital landscape model back into built reality
closed the loop back to the site.
This work argues for a stronger link between the site and the design within a
holistic design approach and the integration of the factor human in digital design
methods. The main objective of using digital tools in design should not be
for its own sake, but rather to strengthen the role of the designer and promote
diverse, site-specific architectures.
This work is part of the National Centre of Competence in Research (NCCR)
Digital Fabrication (DFAB) and the Construction Robotics research stream.
