COASTAL EROSION, MAPPING, MODELLING & TESTING

Real time laser mapping for monitoring coastal erosion and rockfall 3D Laser Mapping, a global laser scanning technology provider and Durham University have created an innovative monitoring system to provide real time 3D data on coastal cliff erosion. The project is part of a KTP (Knowledge Transfer Partnership), a scheme funded by Innovate UK, which has a track record of improving businesses’ competitiveness, productivity and performance by accessing the knowledge and expertise available within UK Universities and Colleges.

Understanding the nature and mechanisms of cliff erosion is of vital importance to predicting the likely

future movement of the coastline. Research on eroding coastlines has been limited by the need for surveys of coastal areas, which are restricted to periods of low tides each month.

The project aims to try to understand the processes of coastal erosion by looking at projected increases in sea level and stormy weather. It aims to understand the process through which wave erosion at the base of the cliffs causes undercutting of the cliff slope which results in an unstable cliff and failure of material that falls into the sea. Whilst this process may at first glance appear straightforward, research by Durham University over the last decade has shown current understanding to be largely anecdotal. The linkage between waves and erosion evolves gradually through time, and is one that responds to a wide range of factors, and not just the action of waves alone.

The project seeks to take advantage of uniquely high-resolution, 3D data being continually captured, to generate unprecedented detail on the changes experienced at cliffs. The 3D Laser Mapping Site Monitor system automatically schedules the capture and analysis of 3D laser scan data in parallel

with environmental monitoring data. The seaside town of Whitby now has one of – if not the most – intensively monitored rock faces in the world.

The project provides constant and frequent measurement of the cliff face, to

allow changes resulting from rockfall to be recorded and analysed in real time. The system is designed to scan the cliff face 24 hours a day at 30 minute intervals. Within each scan measurements of the cliff face are taken at approximately 10 cm

intervals, generating over 2 million points per scan. Whilst this data capture is itself uniquely innovative, the analysis of such a large volume of information presents significant challenges. To overcome this, the system streams data live from Whitby to Durham, where new algorithms have been developed to process the 3D data to extract rockfall volumes in real time.

Using these results, the project is designed to tackle the challenge of precisely monitoring coastal cliff erosion and gain a new understanding from this. For example, it is known that many landslides and rockfall are preceded by precursors, such as smaller-scale movements or smaller rockfall, yet capturing data with sufficient resolution and frequency has up until now not been possible. The intention of this analysis is to investigate these processes with a view to both better forecasting erosion, and also assessing whether such precursors can be used as warnings for future rockfall.

The intention of the research is to move beyond Whitby and the UK’s coasts. The more usual location of 3D Laser Mapping’s Site Monitor system is in some of the world’s largest open pit mines, where rockfall and slope failure presents a significant challenge for sustaining mine productivity. The insight into the fundamental mechanics of how rockfall evolves, gained from the research at the cliffs in Whitby, is designed to be transferrable to these settings and enhance the reliability of slope failure early warning systems.

The help of the local community has been key in enabling the infrastructure for this project. The findings will be available through an open access website soon so everyone involved will be able to see the results as they happen.

BUILDINGS, STRUCTURES, MODELLING & TESTING

Dynamic response of tall timber buildingsTimber buildings have well established economic, social and environmental advantages over other structural options. In particular, their low carbon footprint and high strength to weight ratio makes tall timber construction an attractive solution for satisfying the pressing housing demands in densely populated areas at minimum environmental costs. However, due to the low mass and flexibility typical of tall timber construction, concerns regarding their dynamic behaviour have been raised.

An MSc research project conducted at Imperial College London by Ishan Abeysekera, funded by the

Institution of Structural Engineers, has examined the dynamic response of tall timber buildings of different configurations subjected to Tornado and Downburst wind loading. Four buildings incorporating: i) solid cross-laminated-timber (CLT) shear-wall systems, ii) glued-laminated (Glulam) frames, and iii) hybrid systems, were studied.

Buildings of 7, 11, 20 and 30 storeys were modelled and analysed in the Finite Element software SeismoStruct. Particular attention was given to the accurate representation of the connection behaviour as well as material and structural damping. Wind velocity series were generated following typical Tornado and Downburst distributions and extensive response history analyses were performed. The results were discussed in terms of peak acceleration levels attained at selected locations throughout the height of the building considering varying frequency ranges. The software SeismoSignal was employed for post-processing.

A comparison against international performance criteria for user comfort as set out in ISO10137 revealed the inability of the buildings studied here to satisfy the codified acceleration limits. Therefore, additional analyses employing tuned-mass-dampers (TMD) tailored to the most demanding frequency response in each case were carried out. It was found that TMDs with an active mass of 5% of the total building mass are able to produce up to a 50% reduction in peak acceleration levels. The models proposed as part of the present study constitute a fundamental step towards the assessment of alternative response modification strategies as well as the development of numerical tools for the future optimisation of TMD designs.

1.Introduction • Tall timber buildings are gaining importance as a sustainable alternative to concrete and steel buildings.

• Due to their low mass and high flexibility the performance of tall timber buildings under transient wind loads are under question.

• This study aims to assess the performance of 4 configurations of timber buildings under transient wind loads by means of numerical analysis against the comfort criteria set out in ISO10137[1].

2.Modelling

3.Wind Loading Two types of wind profiles are considered: i) downburst, and ii) tornado (see Figure on the right). Generated wind load profiles were applied to all 4 building under consideration in the direction parallel to the strong axis (i.e. causing bending about the weak axis).

Based on experimental data the analysis was run for various values of damping ranging from 3 to 13% of the critical value.

5.Results The floor acceleration histories were post-processed in order to compare the building response with codified criteria. Results are presented below for the top floor in all buildings under study with approximately 10% viscous damping.

Building 1

• Cross Laminated Timber (CLT) building with steel connections.

• The CLT panels were modelled as rigid frames and the connections as equivalent springs. This is justified by the fact the most of the flexibility of the building comes from the connections (shown below).

• Floor modelled as rigid constraints with concentrated masses at floor levels.

Building 2

• This building employs Glued-Laminated (GluLam) beams and columns, CLT cores and a CLT slab flooring system.

• Floors are modelled as rigid constraints, with all the building mass concentrated at the floor levels.

• CLT cores modelled with equivalent elastic beam-column sections.

Buildings 3 and 4

• Based on the research project by Skidmore Owings and Merrill, SOM [2].

• These buildings use a composite framing system with concrete and timber elements.

• Walls and columns are modelled as elastic frame elements.

• Full-strength connections assumed for beam-column joints.

• Floors are modelled as rigid constraints with floor masses and vertical loads simulated as lumped mass elements.

6.Conclusions • Downburst loading appears to be more critical for lower buildings

(Buildings 1 to 3) whilst tornado loading is more critical for tall buildings (Building 4).

• When subjected to downburst action, all buildings fail to meet the ISO10137 criteria for the full range of frequencies analysed.

• TMDs with an active mass of 5% the total building mass are able to reduce in nearly 50% the peak accelerations. Further studies should be performed leading to optimized designs of TMDs.

CONSTRUCTION, PROCUREMENT, CORPORATE SOCIAL RESPONSIBILITY

Understanding the social impact of construction: connecting CSR with public sector procurementPublic sector procurement represents approximately 26% of all construction work procured in the UK (Office for National Statistics, 2015). Arguably long overdue, public sector workload is being consolidated into packaged frameworks via a variety of novel organisations acting as agencies. Essentially, these organisations act to increase public sector buying power and widen the requirements to work with the public sector beyond the traditional project deliverables of time, cost and quality, to include aligning contractors’ Corporate Social Responsibility (CSR) activities with that of the clients’ responsibilities to the public.

The frameworks potentially offer a high value workload over a long duration, which allows the

public sector to demand in an ever more authoritative voice that their CSR targets are met. Concurrently, public sector budgets are being subjected to unprecedented cuts, and to an increase in public scrutiny. The accumulation of these arguments concludes that public sector bodies want to achieve ‘more for less’ when financing construction projects, and have the long-term high-value frameworks to add weight to their demands. Consequently, public procurement is now a powerful vehicle to drive and govern their CSR agendas in society, with meeting these CSR requirements pivotal to a main contractor’s ability to win public sector construction work.

However, stating their CSR commitments is the easy and well-used rhetoric of main contractors; capturing, measuring and illustrating the positive impact their CSR agendas have upon society is the difficult, but increasingly expected, next step. In the awarding of public sector contracts, clients will review this impact and so, to gain any real competitive advantage, main contractors will need to ensure their CSR agendas are thoroughly adopted internally, with rigorous measurement and communication processes in place to guarantee the impact assessment implemented is accurate.

There is therefore a need for research to further explore CSR, demonstrating

how construction works can meaningfully contribute to society. Of particular importance is the way CSR agendas are set by main contractors, internally and externally communicated, and then mobilised and measured at a grass roots level. It is only with success in all three of these areas that a main contractor has a CSR agenda that will positively influence their public procurement opportunities.

An ongoing collaborative research project between Loughborough University and Wilmott Dixon is actively exploring CSR strategy in the public procurement arena within the areas outlined above.

To date, the research has successfully completed a pilot study of how CSR strategies are communicated within the hierarchy of a main contractor’s organisational structure, to help explain any gaps between CSR ideals and the delivered reality. The research found that, as the CSR strategy diffused down the organisational hierarchy, the knowledge and awareness of its wider societal and business impacts reduced.

By actively exploring how actors made sense of and engaged with a CSR strategy, opportunities to improve the delivery of CSR and the inherent

limitations of current models of delivery were highlighted. Future research is planned to further explore the role of CSR, and will seek to establish any links from the success of internal CSR communication to the effectiveness of CSR measurement, and in turn how the accuracy of this measurement data can lead to public procurement success.

CIOB Innovation and Research Awards: 2014 winners Each year the Chartered Institute of Building (CIOB) recognises the highest levels of achievement in research and innovation across the built environment through its International Innovation and Research (I&R) Awards. In the first quarter of each year, the judging process is concluded and awards for the previous year are announced. By recognising best practice, the awards aim to raise performance levels and ultimately improve the quality of the built environment. Importantly, the awards also encourage the brightest industry newcomers, the recent graduates and postgraduates who are already making a valuable contribution and could lead on innovation in the future. The 2014 competition registered 178 entries from 17 different countries. Six Premier Award winners were selected to recognise their outstanding achievements in academic research and industry innovation. You may remember that the 100th issue of Innovation & Research Focus also included an article on the I&R Awards, covering the 2013 winners.

CIOB’s International I&R Awards cover any built environment related-area and this is reflected in the range of

winners that cover the six different categories of awards. The six categories are: Innovation Achiever’s Award, Digital Innovation Award, Undergraduate Dissertation Award, Masters Dissertation Award, Research Paper Award and Innovation in Education & Training Award. On page 1 you will find an article on Utterberry Wireless Sensors, winner of the Digital Innovation Award. For each category there are three levels of awards – the highest ranked Premier Award, the Highly Commended, and the Merit Award.

The Innovation Achiever’s Award recognises outstanding industry-based innovation that has improved upon – or extended beyond – current expectations of best practice. The Award aims to celebrate individual excellence in innovation. The 2014 Premier Award winner in this category went

to Robert Harris and Stanley Whetstone for their innovation ‘OxypodTM: A Clear Solution to Energy Efficiency’.

The OxypodTM is an egg shaped device developed by Stanley Whetstone from an original idea formulated by builder Robert Harris. The development received financial support from the Goodwin Development Trust. Used in closed-looped heating systems, the device removes trapped and dissolved air from the system, boosting energy efficiency by as much as 30%. Air trapped in water in closed-loop heating systems causes corrosion in the pipes, leading to the formation of magnetites, or “black sludge”. It also slows the water down, makes it harder to heat and causes extra pressure and strain on the system. The benefits of installing OxypodTM include: significant energy reduction in all types of systems; faster heat up and recovery times; lower running temperatures and greater comfort levels. Radiators

The importance of research and innovation in the safety performance of building projects was highlighted in the Research Paper category. The Premier Award went to Dr Yingbin Feng from the University of Western Sydney, Australia. His study investigates the effect of investment on safety performance, and identifies some key influencing factors. A key finding in his study indicates the importance of site culture and project conditions. Investment in basic safety has a stronger positive effect on accident prevention if the project already has a robust safety culture and project hazard level. On the other hand, corresponding levels of investment in projects with a poor safety culture will not yield such positive results. The findings suggest that increasing protection and creating a safer environment will not necessarily raise safety performance if site culture has also not improved. So contractors’ interventions should combine physical protection with other cultural safety measures.

The last award category is the Innovation in Education and Training Award. The top award in this category went to Dr Robby Soetanto who teaches construction management at Loughborough University. He is responsible for developing the BIM-Hub, an innovative teaching and learning approach for future built environment professionals to work in a BIM (Building Information Modelling) environment. With increasing international collaboration in the building industry resulting in fast-growing demand for professionals that can work in virtual teams within online BIM environments, built environment students with BIM competencies will have a competitive advantage in the job market. The BIM-Hub initiative explores how educators can help students hone their BIM competencies, and their ability to collaborate internationally in a real time collaborative BIM environment.

Two of CIOB’s award categories are open to students, either undergraduates or masters students. The international nature of the awards was highlighted amongst student award winners with universities represented from the UK, Singapore and Nigeria. In the Masters Dissertation Category the Premier Award went to Dean Elder from the University of Ulster. His research looks at improving the safety of single carriageways in Northern Ireland. His study examines road traffic collisions on single carriageways, exploring the performance of wide

RESEARCH & INNOVATION, CONSTRUCTION FUTURES

ICE and Innovation & Research: a look to the futureRoger Venables, IRF Editor writes: In Issue 100 of IRF, we carried Mike Chrimes’ reflection on the history of ICE’s involvement in research & innovation in civil engineering. It therefore seems more than appropriate to carry in this starter issue for IRF’s second century a look forward in the same area by Mike’s successor, Nathan Baker, Director, Engineering Knowledge at the Institution of Civil Engineers.

With the volume of data about our environment and infrastructure ever increasing

– and seemingly the pace of change – there is a growing demand to be able to deal with the challenges in civil engineering and the wider infrastructure communities with increasingly innovative, yet still straightforward, solutions.

The global challenges that we face – such as climate change and mitigation and adaptation to it, increasing populations, increasing resource scarcity and the digital revolution – are compelling us to approach problems from a number of different angles and in different ways.

In addition, it seems that experience is being gathered earlier in people’s lives – the definition of experience is changing as people are less specialised and less concerned about detail – often due to a reliance on experts and the use of regulation and standards.

Engineers have a huge opportunity to lead innovation. They deal with real problems (we are sometimes allowed to call them problems, not just challenges!) that need solutions that work today and can be adapted and continue to be used in the future. They understand the detail as well as strategic issues in infrastructure, and the need to be able to set standards. Most importantly perhaps, engineers see the value their solution adds to people’s lives on a daily basis.

So what drives innovation? My view is that, first and foremost, innovation comes from constraint. If there are boundaries or issues that have not been solved, innovative thinking can get around the block to get to a solution. The second component in innovation is to take a risk or two and do something that has not been done before. In the 19th Century, engineers all dealt in risk to solve problems within constraints.

Those constraints may have been about materials performance, time, money or the environment but the engineering ‘gods’ thought innovatively and took a calculated risk – but it was risk.

The issues of the modern world require engineers to take a similar approach. The global challenges we face are enormous and can only be solved by creative thinking, effective risk management and sustainable application.

For civil engineers and the ICE this means we must work collaboratively,

not just with each other and our supply chain partners but with other sectors, stakeholders and decision makers.

Materials technology, people management, academic research and risk mitigation have all moved on. As we become a global community, the diversity of thinking required to solve problems means that we must all embrace change, promote diversity and work together.

We need also to recognise that great ideas can come from anywhere – to exclude them just because they do not come from our current perceived field of expertise is wrong. Academia, by definition, is pushing the boundaries of thinking – this needs to be embraced and harnessed and be applied to today’s and tomorrow’s solutions.

The Institution of Civil Engineers is the logical home for the bringing together of this thinking and the facilitation of

networks and conversations to drive innovation. As the facilitator, the ICE will make a step change in bringing stakeholders together to debate and solve issues. These issues will not just focus on today but also seek to identify issues for the future, to enable debate, planning and mitigation strategies to be implemented.

The ICE learned society is a network of subject experts and special interests. We are moving towards being the home for innovative thinking and, as we begin to think about the ICE bicentenary in 2018, we are reflecting on the lessons

of the founders – to promote the art and science of civil engineering.

We should try to identify what lessons we have learnt from them that they applied successfully to drive their generation’s revolution – and those that we have forgotten. From that, we need to draw out what we can then apply to our revolution. The ICE evolves to the environment in which it works, but a constant is the need to

innovate and solve societal problems to improve people’s lives.

ICE knowledge sits within the minds of the people with whom we interact and, in the modern digital world, we can make it more accessible than ever before. Increased use of technology and bringing the lessons of the past to life will enable innovation to flourish and for civil engineering to come to the fore within the minds of decision makers and the public alike.

The challenge for innovation in design and construction of infrastructure is how that infrastructure will need to change in the light of many factors, including the digital revolution, our increasing understanding of global warming and climate change and how to adapt, increasing size and mobility of populations, and how best to

use new materials, to name but a few (images cour tesy of Roger Venables).
