Welcome to the Modern Methods of Construction Research Group (MMCRG) webpage! The MMCRG was established in 2021 by Dr Daniel McCrum to bring together researchers, academics and industry partners to tackle challenges faced by Modern Methods of Construction (MMC).
The Challenge – Offsite MMC have been lauded for their ability to meet building/housing targets while achieving high quality, lower onsite construction time, simplification of end-of-life recycling, but also reducing embodied carbon and waste. Despite the benefits of MMC, uptake has been low, largely due to lack of; guidelines, shared experimental and numerical data, training, and capital investment. The MMC-RG aims to address these issues and help the construction industry transition from construction towards manufacture.
Construction Technology Centre
Dr Daniel McCrum will be leading the team in one of the five pillar challenge areas (productivity, affordability& cost) in the new Enterprise Ireland funded Construction Technology Centre (www.constructinnovate.ie). The centre was officially launched in July 2022 and is being hosted and led by NUIG (Prof Jamie Goggins & Dr Magdalena Hajdukiewicz). The consortium consists of 22 multidisciplinary research groups across 5 partner institutions, with over 300 researchers currently research active on topics related to construction & built environment.
The centre will bring together leading academics, industry experts, governmental agencies and practitioners to make Ireland a global leader in modern methods of construction, sustainable construction and built environment technology. Over the next five years, Dr Daniel McCrum will be working with all interested stakeholders and the core consortium team (UCD, NUIG, TCD, UCC & IGBC) will foster innovative approaches to modern methods of construction, next generation building material, sustainability and collaboration.
Novel CONnection design and modelling idealisations utilising CATENAry acTION in the disproportionate collapse resistance mechanism of cold-formed steel panelised structures (ConCatenaTion)
Modern methods of construction (MMC) are highly precise, improve safety and reduce waste due to streamlined manufacturing and construction processes. However, lack of guidelines on the interaction between structural components and connection behaviour hinders their use worldwide. Panelised, load-bearing, cold-formed steel construction is a MMC that offers several advantages compared to standard construction techniques, including reduced construction-related carbon emissions. However, little is known about the robustness of such structures as testing and modelling data are scarce. Funded by the Marie Sklodowski-Curie Actions programme, the ConCatenaTion project plans to develop novel connection prototypes, design guidance and idealisations that should enable robust design of panelised cold-formed steel structures against disproportionate collapse, whilst utilising advantageous catenary action as a collapse resistance mechanism.

Advancing the structural safety and efficiency of modular construction connections under normal and extreme loading conditions
The research project is investigating some of the key issues that limit the current performance of modular construction from the structural efficiency perspectives and assess the suitability of using traditional building codes in modular construction. The research aims to address the following issues: (1) stresses induced in adjoining structural members due to differential shortening of columns when more and more modular units are stacked on top of each other; and (2) assess the applicability of existing progressive collapse mitigation design rules that have not been developed for use in modular construction. This research project is in collaboration with Michael J Hough Structural Engineers (www.mjhse.com).

Experimental and analytical investigation of the behaviour of cold-formed steel (CFS) stud & track sections in panelised construction subjected to progressive collapse loading
Cold formed steel (CFS) load-bearing frame (or panelised) construction, is an increasingly popular MMC that offers remarkable advantages to its hot-rolled steel counterparts including higher strength-to-weight ratio, high durability, lighter weight, and thus, ease of handling, shorter build times, and reduced construction-related carbon emissions (e.g. foundation requirements). There is little understanding of CFS structural resistance to disproportionate collapse under loss of support, highlighted by a lack of testing and modelling. This research project will provide much needed physical testing and numerical modelling of CFS panelised construction under disproportionate collapse loading conditions.

Dr Sun completed his BEng in Civil Engineering at Tongji University (2016), his MSc in Structural Engineering at Imperial College London (2017), and his PhD at Nanyang Technological University (2020), where he was also involved in a large Singaporean research project on composite structures funded by the Ministry of Education, Singapore. Upon completion of his PhD, Dr Sun was appointed as a Lecturer by Xi’an Jiaotong-Liverpool University. In 2022, he joined University College Dublin as an Assistant Professor in Structural Engineering. Dr Sun's research focuses on high-performance steel structures and modern construction methods.
Xuekang Guo completed his bachelor’s degree of Civil Engineering from Henan University of Urban Construction in 2016. Xuekang continue his research career in Beijing University of Technology (BJUT) since 2017 during this time he got his Master degree and then move to his Ph.D. candidature. Xuekang’s research topic is the structural resistance of reinforced concrete shear walls against blast and progressive collapse. Funded by China Scholarship Council, he will join Dr Daniel McCrum’s research group for the next year (January 2023 to January 2024) as a
visiting scholar, to proceed his topic under the guidance of Dr. Daniel McCrum (UCD) and Prof. Yi Li (BJUT).
