The research considers two major case studies where modularisation has been used to minimise complexity and increase standardisation. Referred to in this thesis as ‘construction product prototypes’ and ‘building design prototypes’, the two studies examine firstly the product development of an Intermodal Steel Building Unit (ISBU) used in multi- storey construction and secondly a modular station pre-design used and repeated on four station buildings. The ISBU is based on a standard ISO dry-freight container and its use in modular construction maximises the use of factory based off-site methods (OSM); this should improve consistency of product outcome with minimised impact on site. Very little academic work has been published on ISBU modular construction. The research therefore looks in detail at the process of ISBU modular product development and its engineering performance. It also compares production and procurement of the units on supplier-driven accommodation buildings in comparison to similar but non-modular client-led projects. Using multiple stages of project team interviews and project document analysis, the research data is coded, measured and analysed to describe the processes of product and design prototyping. The research demonstrates that the ISBU product was developed and refined through several major building projects and has reasonable engineering performance characteristics but may be more suited to temporary buildings. The principle of modular pre-designs as found in stations has benefits for rationalising the design process and simplifying and internalising complexities of construction. The research considers solutions for problems that are ill defined and a design process that is difficult to assimilate. This part of the research uses models for framing and problem/solution co-evolution to solve problems of ill definition and linear/non-linear design processes by building on Gero’s (1990) design prototyping theory model. Modularisation of the station designs was successful in reducing design effort and allowed a repeatable pre-design to be refined, but the design team struggled with the bespoke nature of the project designs. The comparison of case study data to models for manufacturing, procurement and design prototype development has led to a better understanding as to how these designs were achieved and how these same approaches could be applied in future.

The research was conducted within an industry context and sponsored by Buro Happold Consulting Engineers. The EngD is examined on the basis of this discourse, supported by five peer-reviewed publications. Presented within the appendices section of this thesis are four conference papers and one journal paper, all of which were authored by the candidate. The main body of the text provides an in-depth overview of the work undertaken, the context, findings and implications for the sponsor and industry. Further details are explained within the papers included in the appendix section. iii ISBU Modular Construction and Building Design Prototypes USED ACRONYMS / ABBREVIATIONS 2D Two-Dimensional 3D Three-Dimensional ACSA American Collegiate Society of Architects AI Artificial Intelligence ARCOM Association of Researchers in Construction Management BAA British Airports Authority BIM Building Information Modelling CABE Commission for Architecture and the Built Environment CAD Computer Aided Design CAM Computer Aided Manufacture CIB Conseil International du Bâtiment (now International Council for Research and Innovation in Building and Construction) CIMC China International Marine Containers Group Ltd.
