In this presentation the speaker will present a summary of his over two decades of experience and exposure to the field of large‐scale 3D printing which he founded, the history of the field, major developments, current status of research and commercial developments, and future potential of the field in a variety of prospective domains.
Dr. Behrokh Khoshnevis is the CEO of Contour Crafting Corporation (CC Corp) and is a Dean’s Professor of engineering at University of Southern California and is a Fellow of the National Academy of Inventors and a member of the EU Academy of Sciences. Through his inventive research activities he has made many useful inventions and innovations in different domains including robotics, haptics, biomedical, oil and gas, renewable energy, fabrication, construction and space systems. Contour Crafting, his automated construction which was invented two decades ago, was the first large scale 3D printing technology and is regarded as a promising approach for terrestrial building construction and planetary construction of human outposts. A prestigious NASA organization awarded Contour Crafting the Grand Prize of the Create the Future Design Contest among 1000+ globally competing technologies. In 2016 another invention of Khoshnevis, SSS, received the top NASA prize in an international competition on in-space fabrication technologies.
Dr. Khoshnevis has nearly 200 technical publications, and holds over 100 US and international patents. He has developed products that help people worldwide. He is a NASA Innovative Advanced Concept Fellow, a Fellow of the Society of Manufacturing Engineers, a Fellow of the Institute of Industrial & Systems Engineering, and a Fellow of the Society for Computer Simulation. He was recognized in 2016 by the Connected World magazine as one of ten pioneers in the Internet of Things (IoT). Dr. Khoshnevis is recognized worldwide as the founding father of large-scale 3D printing in which he has numerous publications, patents and awards.
Additive manufacturing techniques applied to concrete have the potential to reduce construction cost and time by eliminating the need to erect formwork. To manufacture concrete structures without formwork, in a layer‐by‐layer fashion, the concrete must be able to support the weight of the material above while maintaining the ability to be pumped through a pipe. Large amplitude oscillatory shear (LAOS) is used to assess nonlinear viscoelastic properties of cement paste with limestone powder at intervals of approximately 15 min. To assess the “3D printability” of the cement/limestone paste, structures are built with a custom‐built cement 3D printer. The structures are scored against a rating system and related to the measured viscoelastic properties at the time of printing.
Dr. Scott Z. Jones graduated from University of Maryland Baltimore with a Ph.D. in Mechanical Engineering in 2016. He is currently the project leader of the Additive Manufacturing with Cement-based Materials at the National Institute of Standards and Technology. Scott’s project is focused on developing test methods and measurement techniques to assess the integrity of structures fabricated with cementitious materials by additive construction methods. He is the head of the Metrology for Additive Construction by Extrusion (MACE) consortium at NIST.
A quick evolution of the construction methods and techniques is occurring in industry with the establishment of automatized application with durable and sustainable materials having lower carbon dioxide finger print. Alternative binders like slag, limestone, fly ash and clay are thanks to new chemical accelerators and plasticizers increasingly used to replace Portland cement. New development tools have been developed to make a quantitative link between laboratory and field and to allow quick adaptations with any local raw materials for local manufacturing. In 2016 Sika built a dedicated 3D center for automated building construction. The ongoing activities concentrate on the first industrial implementations of 3D, as well as creating an unrivalled freedom of design with infinite architectural design possibilities.
Dr. Didier Lootens is a Physico-Chemist leading the Department of Material Physics in the Central Research of Sika Technology, Zurich, Switzerland, responsible of the modernization of the laboratory technologies in 35 countries. He received MSc in Physico- Chemistry from the EcoleSupérieure de Physique and Chimie Paris and his PhD from the University of Pierre et Marie Curie. His research interests include supplementary cementitious materials, formulation and characterization of grout, mortar and 3D printed concrete for the control of their early age properties such as rheology, volume change or strength development.
The overall emphasis of this presentation is to discuss waterproofing systems for below grade structural applications with an emphasis on foundation walls and under slab applications. This technical presentation will begin with a discussion covering the definition of waterproofing versus damp proofing, a brief history of waterproofing, and an examination of the typical types of structures that require below grade waterproofing. The presentation will then discuss the design considerations that affect the selection of a waterproofing system, including water management, waterproofing location, and protection system.

Premature deterioration of construction materials due to water intrusion, weathering and/or air leakage is preventable in both new and existing construction. This technical seminar will examine the building envelope as a complete system: *The evolution of the building envelope and modern design expectations. *Examine the Control Layers Approach to building envelope system design. *Discuss the benefits of a systematic approach to the various elements of the building envelope.
