The recently completed New Engineering Building (NEB) at the National
University of Ireland, Galway (NUIG) is a new state of the art academic
facility on the university’s north campus. The building unites all five
engineering disciplines within the university and at 14,250m² is now the
largest engineering school in Ireland. It represents a milestone in the
construction of engineering educational facilities by incorporating the use
of numerous types of sensors to create an interactive learning environment
for engineering students. Not only will it be a centre of education, but the
building itself will act as a ‘living laboratory’ and teaching tool. This paper
outlines the instrumentation of the structural elements within the building
and the part they will play in the teaching and understanding of structural
engineering within the university.
The Drapers’ Gardens redevelopment, completed in 2011, involved the construction of an office building in the Bank Conservation Area within the City of London. The confined city site and the ground conditions presented a number of challenges. The site activities commenced with the demolition of the existing 100m high tower structure. At the time it was the tallest office structure to be demolished in the UK. The perimeter support of the substructure was designed to minimise internal propping. The piled foundations re-used a substantial number from the existing piled raft.
Archaeological investigations uncovered an extensive area of preserved Roman development and water channels. The building obtained an excellent BREEAM rating which influenced the services and façade design. This led to demands on the structural design. The steel framed structure above ground is a distinctive stepped form rising to 15 storeys with spans up to 15m to satisfy the developer’s desire for column-free spaces. The staircases on the south façade are a visible feature.
Close working within the multi-disciplinary design team and with the main contractor ensured this complex project was efficiently completed.
Both criminal and civil law is relevant to the management of health and safety risks. The criminal law i.e. that made in Parliament (and much of which originates from the EU) is relevant to all workplaces and work related activities, but is specifically relevant because of the significant risks arising from construction activities.
Why report to CROSS?
Alastair Soane, Director of Structural-Safety.org urges more engineers to engage with the programme, dispelling some reporting myths and highlighting the community-wide benefits of submitting concerns.
This Technical Guidance Note concerns lateral loads that are applied to barriers and wheel axle loads from vehicles. Barrier loading is dealt with slightly differently to other forms of imposed loading. The nature of the loading can vary from people leaning against barriers to vehicles colliding with them at speed. Axle loading from vehicles has to be treated somewhat differently to other forms of imposed loading. While it is possible to assume a blanket area load to represent them, it is the point load from each wheel that needs closer attention.
There has been recent increased use of earth for construction of buildings in developed countries, largely because of concerns with the environmental impact and embodied carbon from fired bricks and cement-based products. Of all forms of earth construction, the widest impact on modern construction is likely to come from commercially produced unfired earth masonry where large-scale production can significantly reduce costs.
While there are benefits to using earth masonry, structural design with earth masonry raises some specific issues that are not necessarily relevant to other forms of masonry construction. This paper summarises these issues and presents results of extensive structural testing on modern earth masonry. The structural properties required for design are compared with typical values for other masonry types in Eurocode 6, showing that commercially produced earth masonry can meet or even exceed the structural capacity of other commonly used masonry systems.
Kevin Lea, BIM Business Development Manager at CSC, provides a personal view on what BIM really means to the structural engineer and whether Structural BIM is being used to its full potential.
