What does BIM mean for Civil Engineers?Chun Keung Ng
BIM is a norm for the building industry. How about for infrastructures? Some countries are over confident on the implementation of BIM in both building and civil engineering industries. Is the BIM technology for infrastructures mature and easily available? Are the professionals ready for BIM?
OPEN BIM is a universal approach to the collaborative design, realisation, and operation of buildings based on open standards and workflows.
The Industry Foundation Classes (IFC) data model is intended to describe building and construction industry data. It is a platform neutral, open file format specification that is not controlled by a single vendor or group of vendors. It is an object-based file format with a data model developed by buildingSMART to facilitate interoperability in the architecture, engineering and construction industry, and is a commonly used collaboration format in Building information modelling based projects.

COBieOWL An OWL ontology based on COBie standardAna Roxin
Presentation made on October 28th 2015, at The 14th International Conference on Ontologies, DataBases, and Applications of Semantics (ODBASE2015), Rhodes, Greece.
We describe our method for semi-automatically conceiving an OWL ontology for the COBie standard starting from a COBie spreadsheet template. We call this ontology COBieOWL and we populate it directly from COBie spreadsheet data files as used by building actors. We also discuss various benefits of adopting our approach, for example: it reduces semantic heterogeneity of the COBie model.
While Autodesk was pushing a transformative method developing AutoCAD, a enlightened upstart called Revit, entered the market. Parametric-driven plan programming was not new, but slightly Revit brought a database approach where 2D, 3D, or calendar gets all refresh as single database mechanisms. Likewise new was the idea of the family reader where clients could outline and tweak mechanisms for their own particular utilize. It didn't take ache for Autodesk to buy Revit and announce it their "lead" for the compositional market.

What is Level of Definition?
When creating an information model as part of the #BIM process, you would not expect to have all your data collated right from day one. The aim is to deliver the right information, in the right format, to the right people at the right time.
A building information model contains both graphical and non-graphical information, accurately linked, clearly defined and well structured. As stages progress and proposals develop, the graphical and non-graphical data builds in a shared digital space, known as a Common Data Environment (#CDE). The different amounts of data are termed Levels of Definition.
When BIM tools and processes are combined with the desire to collaborate, the building design and construction project results are superior to projects using "traditional" methods. This presentation begins with a series of definitions and examples of BIM and includes a wide variety of projects where BIM saved the day for the team.
In this presentation I gave one overall overview about BIM workflow for Construction and D&B companies.
BIM is not a tool, BIM is not a software, BIM is a way of thinking about the project and put together processes to exchange information during the entire lifecycle.
This presentation is mainly focused on Autodesk platform but is applicable to many other solutions.

Panel: Digital Humanities fo Cultural Heritage II.
Author: Paolo Borin. Chair: Caroline Bruzelius.
Abstract: The dissertation presents the importance of applying contemporary digital modelling techniques to historical buildings analysis. As of today, the 3D visualization should go beyond simple visual depictions of a past condition. It is necessary to represent the architecture toward intelligent tools, which support information integration providing linking, shape-related analysis and provide the necessary semantic information and relations. Towards a unique Historical Building Information Modeling (HBIM), it becomes easy to relate parts of the same or different buildings, offering to for historic researchers a real model-based knowledge base, new disruptive perspectives of analysis and conservation criteria. Consequently, it is necessary to study new ontologies for historical building, related to new object classification, but derived from Renaissance architectural treatises. A case study of the Church in Padua validates the concepts’ explanation.

On the relation between Model View Definitions (MVDs) and Linked Data technol...Ana Roxin
This white paper outlines the proposals from the Linked Data Working Group (LDWG) on how technologies and approaches that are common to the domains of Semantic Web, Linked Data, and the Web of Data (hereafter jointly called ‘Linked Data’) are related to Model View Definitions (MVDs). After a brief introduction of both the MVD concept (Section 1) and linked data technologies (Section 2), two main topics are discussed:
● Technical: handling MVDs with Linked Data technologies (Section 3)
● Industrial use cases: making most from the traditional MVD approach and Linked Data technologies (Section 4)
The purpose of this white paper is to discuss how Linked Data technologies and approaches could be effectively deployed to support industrial use cases that are typically related to the generation, use and maintenance of MVDs.
This presentation discusses BIM4fm and using COBie to create asset information requirements, and references the BIM4FM project at Sydney Opera House. The presentation is based-upon research completed by the Sustainable Built Environment National Research Centre at Curtin University, Perth, Australia.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

This research focused
on the UK scenario, since:
• the UK Goverment’s initiatives could become a
framework for the European States which
do not yet submit a BIM policy;
• the importance of the UK construction
business in Europe, especially regarding
private housing and commercial, where curtain
walls are commonly used;
Moreover, curtain walls are products that typically

cycle:
it could be useful to

Non-collaborative procedure based on COBie .xml:
there could be several issue in aligning information
produced by the different stakeholders.
Automatic exportation of all the information included in the model,
relating to Contact, Facility, Floor, Space, Zone, Type,
Component, System, Attribute and Coordinate worksheets.

Main problem: what should be considered manageable assets?
premise:
curtain wall
complexity
Ontological complexity
of the considered product
• Design information, at various stages
• Construction information
• Operation & Maintenance information
• Manufacturing-based information
Huge variability of elements
if dimensions are considered
The entire curtain wall can be seen
• as unique object;
• as an assembly composed by several subsystems (cells);
• as an association of single elements.
E.g. in buildings like skyscrapers the hundreds of panels that
constitutes the facade could seem the same panel repeated for
hundreds of times, but they often differs for dimensions.

IDM development
Main problem: what should be considered manageable assets?
• No project-specific indications
• No stable practice on COBie
• Curtain wall complexity
chosen criteria:
Every element:
• which needs specific maintenance operations
• for which replacement parts are provided
• that requires to be specified by additional
documents
• that requires to be specifically described by
those properties expected by the Type
worksheet (e.g. warranty information)
Every curtain wall cell*
is described by a specific
COBie Type
(regardless dimensions)
is exported as a
COBie
Component
*In the general case where
curtain walls are not subdivided
in cells, each element must be
exported as a Component too.

Result: Exchange Requirement example
The ERs used by the COBie
specification included in
NBIMS-US v.3 were used.
Sub-ERs related to the COBie
worksheets were defined.
The specific IFC entity which
compiles a precise COBie cell
(taken from the COBie MVD).
Information to be exchanged is
defined in relation to the COBie

Conclusions
impossibility to reach the actual objective:
exchange of the entire set of information
needed for Facility Management
The best solution if the
purpose is just deliver COBie
data in .xml format, in order
to fulfil a contractual
requirement:
- Easy to use;
- No additional application
needed: all happens within
the Revit environment
Considered scenario:

Conclusions
Hopeful scenario:
using IFC is the only way to
enable interoperability
between the different actors
A MVD for Facility Management which
clearly defines the content of the exchange
and standardizes data flow (also for curtain
walls) is strongly needed.
