This thesis focuses on 4 main problems that we face in construction today.The steps of design and fabrication are perceived separately from material properties which causes a disconnection between different phases in construction processes.

Nowadays, we as designers, have been exposed to a rapid increase in the number of CAD/CAM softwares and digital fabrication machines that aided our design processes and made fabrication more efficient and precise than ever before.

The traditional construction workflow consists of a linear top down approach, Especially in constructions that utilize prefabrication and tries to gain control over the whole process of construction. This also Includes digital fabrication that is doing it in smaller scale.

 

In this linear workflow when a problem is faced it is realised after execution, and then constructor has to go through a time consuming and expensive process of rework and re-planning.  This often results in a long validation process between stakeholders related to the construction job.

On-site Fabrication is still needed, especially when integrating local materials or for  (natural or recycled resources) or for making rehabilitation up-cycling buildings. Intrinsic materials have uncertain behavior which does not fit into standard processes of prefabrication. While  digital fabrication is mainly being used for OFF site prefabrication within such a workflow, This research looks at the possibilities offered by augmented reality ON the construction site.

Difference between the digital plan and the physical reality.

By merging Planning and execution phase in construction, we can integrate a feedback loop  to real-time validation on construction site.

Validation parameters categories consists of Design, Structure and Logistics and are defined as not something static but flexible within a certain threshold.

Finding the optimum point where all validation parameters are respected during the  construction for each fabrication step based on real-time 3D scanning feedback.
