About Us

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.

Research

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 McCrum worked as a consulting structural engineer for a couple of years in Dublin prior to undertaking his PhD studies in Trinity College Dublin funded by an Irish Research Council Scholarship. After completing his PhD in 2012, Dr McCrum was appointed as a Lecturer in Structural Engineering in Queen's University Belfast. In 2017, Dr McCrum joined University College Dublin as an Assistant Professor in Structural Engineering. Dr McCrum is a chartered structural engineer with the Institution of Structural Engineers (2016).
Dr Samar Raffoul
Research Fellow
Dr Raffoul completed her BSc in Civil Engineering at the University of Balamand (2011), funded by the university merit scholarship, and her MSc in Structural Engineering at the University of Manchester (2012). She acquired her PhD at the University of Sheffield (2018), where she was also involved in two large European collaborative projects funded through FP7 and COST, respectively. In 2018, Dr Raffoul worked for 2 years at a cold formed steel manufacturing company as a KTP research associate, a collaborative role between industry and academia, to develop refined design solutions for modular frame design. She then worked at an offsite construction consultancy before starting her Marie Sklodowska-Curie Fellowship at UCD in 2022. Dr. Raffoul’s research focuses on connection behaviour in modern methods of construction under accidental loading.
