ERPE research has made major impacts on the design and operation of concrete infrastructure through design, corrosion investigation/residual life prediction and non-destructive testing (NDT). New interpretations of ground penetrating radar (GPR) data have impacted international practice through: the American Concrete Institute (ACI) document on NDT of Concrete, ACI 228.2r2013; fib Model Code 2010, ISBN:978-3-433-03061-5; a corrosion monitoring device; and "GprMax", the world's most widely used and acclaimed GPR freeware.
The financial impact of the underpinning ERPE research is estimated at £100M p.a. on infrastructure maintenance savings worldwide.
£80m has been saved since 2008 by London Underground (LU) and yet more by bridge owners in the UK as a direct result of using the Arching Action (AA) enhancements in strength predicted by our research. The associated disruption would have resulted in enormous congestion, losses economically of £ billions and negative social impact. Multi-million $ savings have also accrued in North America from the use of corrosion free deck bridges, which have minimum maintenance, as has our innovative flexible concrete arch (patented 2004) which has been used for over 40 FlexiArch bridges (£15m in contracts) since 2008.
ERPE research, since 2001, into the application of Fibre Reinforced Polymer (FRP) composites for strengthening existing civil engineering structures continues to impact design guidelines for preserving and updating the worldwide ageing infrastructure. The lifetime extension of existing infrastructure and buildings is a priority: the UK Government plans to invest up to £250bn over 10 years to return UK infrastructure to `world class' performance. 75% of developed world infrastructure investment covers retrofitting and repair rather than new-build. FRP strengthening is now the method of choice for seismic retrofit, capacity enhancement, structural repair and rehabilitation of concrete and masonry structures.
ERPE research to enhance strength and structural integrity has been used in the development of, or been incorporated into, at least 12 design guides codes and standards worldwide in at least 5 countries including Australia, Canada, China etc.
This Alliance project demonstrated, through the exploration of flexible formwork techniques, that it is possible to use concrete in a much more diverse, sustainable and quality-controlled way than in 20th century architecture, achieving a 25-35% reduction in the carbon footprint of concrete constructions. It has engendered an attitudinal change within the global construction industry, with one US industry professional saying "Prior to this research, concrete was often perceived of as a harsh, aggressive material. Experimentation with fabric forming has shown that it doesn't have to be so". The research has led to two Knowledge Transfer Partnerships, an award-winning Chelsea Flower Show entry and the proprietary application of the technology in other forms of construction. It has also stimulated partnership working with government and schools; collaboration described as the "Curriculum for Excellence at its best".
By ensuring the durability of notable concrete structures in China, such as the Bird's Nest National Stadium Beijing, Dayawan Nuclear Power Station, Harbin-Dalian Railway Bridges, Qingdao Bay Bridge and Beijing-Tianjin Railway Bridges using Autoclam Permeability System and Permit Ion Migration test, developed by Queen's University Belfast (QUB) and sold by a QUB spin-out Amphora Non-destructive Testing Ltd., the savings in future repair costs are estimated to be hundreds of millions of Chinese Yuan (RMB) (the repair expenditure for the three-year period 2009-'11 was RMB 10.2 billion).
Research on permeability and diffusivity testing of concrete on site since 1993 has led to the incorporation of both the Autoclam and the Permit in a corporation standard issued by the Central Research Institute of Building and Construction (CRIBC), China and the test protocol of Permit in a Chinese railway standard.
The training of construction professionals (including more than 200 senior managers from the Chinese construction industry) since 2008 has impacted on improved sales of Autoclam Permeability System and Permit Ion Migration Test, securing around £500k commercial income, and generating new employment in the UK. Since 2008 these test instruments have been sold to 12 countries.
Research within the Building Research Establishment's sponsored Centre for Innovative Construction Materials (CICM) at the University of Bath has allowed the life of concrete structures to be extended through developing (a) proper methods for assessing existing capacity and (b) the means to increase capacity where necessary. This has prevented buildings and bridges (managed, for example, by large asset owners such as the Highways Agency and Network Rail) from being condemned as unfit for purpose, resulting in vast savings in reconstruction costs and preventing disruption to infrastructure users. The work has led to the researchers being commissioned to write guidance documents that are routinely used by infrastructure owners and consulting engineers worldwide. Over the course of the last eight years this has resulted in several £millions of savings to infrastructure owners and the UK economy.
University of Nottingham research into a composite design for steel beams and floor slabs has resulted in environmental and economic benefits and an important change in the construction industry. The work has reduced the weight of beams and the overall tonnage of buildings, enabled easier installation and improved structural strength. More than 40 projects, with a total combined floor area in excess of 380,000m2, have used the technology since 2008, and the method's market share has been estimated at up to 60%. The breakthrough has facilitated partnerships between steel frame designers and precast flooring manufacturers, with the value to the latter alone put at more than £5M.
The Advanced Concrete and Masonry Centre (ACMC) at UWS was among the pioneers in development of practical self-compacting concrete (SCC) in Europe. As a lead partner, the group contributed to two large EU projects on SCC, which underpinned the European standards on SCC test methods.
The group's research has contributed to the steadily increasing use of SCC in general construction, which has brought many benefits, such as enhanced durability, improved productivity, reduced overall cost, improved working environment and sustainability. Given the massive quantities of concrete being used (>14 billion tonnes/year globally), the increased use of SCC has had important economic, societal and environmental impacts.
Following the North Sea Piper Alpha oil rig accident in 1988 and subsequent Cullen inquiry, new and safer maintenance procedures were introduced. One of the most significant changes was the restriction in the use of welding repairs (hot work) in the maintenance of plant and pipework due to the risk of fire and explosion. Research at Newcastle provided a novel engineering model that formed the basis for implementation of a new repair technology. This used fibre reinforced polymer wraps to restore the integrity of pipes without `hot work' or any interruption of production, thus minimising operational costs and increasing worker safety. This new technology has now become industry standard with new ISO and ASME standards for pipeline repair established as mandatory standards in 2006 and 2008 respectively (ISO/TS 24817 — Composite repairs for pipework; and ASME PCC-2, Repair of pressure vessels and piping). The period 2008-2013 has seen considerable expansion, worldwide, of an industry offering materials and support services to enable composite repairs to be designed and carried out.
Researchers in QUB developed the first commercial process control system (Rotolog) and simulation software (RotoSim) for the Rotomoulding Plastics Industry. There has also been recent commercialisation of a new energy-saving system, the Rotocooler.
The fundamental understanding of the process that was developed also enabled the moulding of new materials for new application areas, notably motorcycle fuel tanks (now used by BMW, Ducati, Harley Davidson and Honda) and the world's first concept car made from sustainable polymers.
Global economic and environmental impact arises from a significantly more efficient process, better product quality, a greater selection of processable materials and thus increased sales.
