Samenvatting

Within BAM Infra (Netherlands) there is a 3D concrete printing facility already. This is the Europe's first commercial and industrial production location for 3D printing of concrete elements for bridges. The idea now for BAM (International) is to also include composite materials in the design of temporary works through 3D printing methods. Prior to this research, a feasibility study was done by Maximilian Foy where it was concluded that it is technically feasible to use 3D Printed birdcages, gangways, and handrails. Nevertheless, the commercial case of 3D printing of temporary works is dependent on the contributing factors such as the costs of the material used, including the productivity and the costs of the 3D printer itself. The following plan aims to optimize the current design (structural and economical wise) for the Tanjung Jati project study case (platforms, gangways, and handrails) and to investigate the required certifications and legal documents to produce such structures and tools. Furthermore, an investigation of 3D printable alternatives will be done within other Opco’s like BAM Infra, BAM Belgium and BAM Nuttall to optimize the productivity of the 3D Printer.

Research objective
To determine (a) potential valuable business case (s) for BAM (International) to apply 3D printed products using composite materials on their (near shore Civil Marine) projects, by studying the technical advantages of the 3D printing technology and composite materials besides providing an structural optimization of the current platform used as temporary works as an initial study case to introduce the 3D printing technology in the construction industry of BAM.

Main question
What is the optimal design of 3D printed temporary works platforms (birdcages) made of composite materials which meet the structural requirements and is economically feasible for BAM International when being produced by means of additive manufacturing and used in near shore civil marine projects (Tanjung Jati study case)?
