Advanced timber construction industry : a quantitative review of 646 global design and construction stakeholders
(2023) Orozco, Luis; Svatoš-Ražnjević, Hana; Wagner, Hans Jakob; Abdelaal, Moataz; Amtsberg, Felix; Weiskopf, Daniel; Menges, Achim
There has been a multi-storey timber construction boom since the start of the millennium. While there is now a body of research on trends, benefits, and disadvantages of timber construction, there is not yet literature on the wider market or the impact of stakeholders on it. This research investigates the (i) architects, (ii) engineers, and (iii) manufacturers involved in the realization of 300 contemporary multi-storey timber buildings from an existing survey. The analysis is based on data sourced from stakeholder websites and the building survey. It evaluates the perceived level of timber expertise of stakeholders based on service categorization and stakeholder type and relates them to the buildings they worked on. The research uses quantitative methods to answer qualitative questions on the connection between architectural variety in timber construction and the stakeholders involved. Interconnectivity between stakeholders and projects is visualized in an interactive network graph. The study shows a segmented mass timber market with relatively few impactful design and construction stakeholders, mostly located in central and northern Europe. It also identifies fabricators as the largest group of innovators advancing the industry and enabling the construction of more complex projects. It reveals the importance of collaboration and knowledge sharing for the industry’s growth.

Advanced timber construction industry : a review of 350 multi-storey timber projects from 2000-2021
(2022) Svatoš-Ražnjević, Hana; Orozco, Luis; Menges, Achim
Throughout the last two decades the timber building sector has experienced a steady growth in multi-storey construction. Although there has been a growing number of research focused on trends, benefits, and disadvantages in timber construction from various technical perspectives, so far there is no extensive literature on the trajectory of emerging architectural typologies. This paper presents an examination of architectural variety and spatial possibilities in current serial and modular multi-storey timber construction. It aims to draw a parallel between architectural characteristics and their relation to structural systems in timber. The research draws from a collection of 350 contemporary multi-storey timber building projects between 2000 and 2021. It consists of 300 built projects, 12 projects currently in construction, and 38 design proposals. The survey consists of quantitative and qualitative project data, as well as classification of the structural system, material, program, massing, and spatial organization of the projects. It then compares the different structural and design aspects to achieve a comprehensive overview of possibilities in timber construction. The outcome is an identification of the range of morphologies and a better understanding of the design space in current serial and modular multi-storey mass timber construction.

Agent-based principal strips modeling for freeform surfaces in architecture
(2024) Chai, Hua; Orozco, Luis; Kannenberg, Fabian; Siriwardena, Lasath; Schwinn, Tobias; Liu, Hanning; Menges, Achim; Yuan, Philip F.
The principal curvature (PC) of a freeform surface, as an important indicator of its fundamental features, is frequently used to guide their rationalization in the field of architectural geometry. The division of a surface using its PC lines into principal strips (PSs) is an innovative way to break down a freeform surface for construction. However, the application of PC networks in architectural design is hindered by the difficulty to generate them and flexibly control their density. This paper introduces a method for PS-based reconstruction of freeform surfaces with different umbilical conditions in the early stages of design. An agent-based modeling approach is developed to find the umbilics and increase the degree of control over the spacing of PC lines. This research can effectively expand the application range of PS-based surface reconstruction methods for freeform architectures.

Co-design and agent-based methods for multi-storey wood building systems
(Stuttgart : Institute for Computational Design and Construction, University of Stuttgart, 2024) Orozco, Luis; Menges, Achim (Prof., AADipl(Hons))
Timber, the most widely used natural material in the construction industry, can sequester carbon as it grows and store it in the built environment. However, due to the logistically mandated orthogonal shape of raw and conventionally prefabricated Engineered Wood Products and the limited single spans they can achieve, most contemporary timber buildings currently only have one of a restricted set of uses, with little possibility for reuse. This limits timber's utility in urban environments, which often require filling in irregular sites and extending existing structures. It also limits the building industry's potential environmental contributions. These restrictions could be overcome by using interdisciplinary organisational and computational design methods. This research investigates new ways to design wood buildings through improved cross-discipline collaboration. First, it evaluates co-design as a means of integrating different disciplines throughout the design process by applying it to the design of a prototype building. Then, it proposes agent-based methods for procedurally and interactively negotiating between conflicting sets of optimisation criteria. Agent-based simulations were developed for the placement of columns, the subdivision of floor plates into fabricable and transportable slab segments, and the reinforcement of these segments with internal members. These developments built upon a framework for timber building systems and their data structures. These methods were then tested on the design and fabrication of timber buildings across a range of scales and resolutions. This research demonstrates that innovative computational and organisational methods can results in an increased design space for multi-storey timber buildings. This results in an expanded palette of building types, and an increased contribution by the building sector to the global environmental and humanitarian housing crises.

Co-design methods for non-standard multi-storey timber buildings
(2023) Orozco, Luis; Krtschil, Anna; Wagner, Hans Jakob; Bechert, Simon; Amtsberg, Felix; Knippers, Jan; Menges, Achim
To meet climate change goals and respond to increased global urbanisation, the building industry needs to improve both its building technology and its design methods. Constrained urban environments and building stock extensions are challenges for standard timber construction. Co-design promises to better integrate disciplines and processes, promising smaller feedback loops for design iteration and building verification. This article describes the integrated design, fabrication, and construction processes of a timber building prototype as a case study for the application of co-design methods. Emphasis is placed on the development of design and engineering methods, fabrication and construction processes, and materials and building systems. The development of the building prototype builds on previous research in robotic fabrication (including prefabrication, task distribution, and augmented reality integration), agent-based modelling (ABM) for the design and optimisation of structural components, and the systematisation of timber buildings and their components. The results presented in this article include a functional example of co-design from which best practises may be extrapolated as part of an inductive approach to design research. The prototype, with its co-designed process and resultant flat ceilings, integrated services, wide spans, and design adaptability for irregular column locations, has the potential to expand the design potential of multi-storey timber buildings.
