    Being Brunel | The Civil Engineering Blog Over the last year I’ve been learning some real practical engineering lessons from the most unlikely of sources: my IKEA Austmarka wardrobe. Brought from that nightmarish trip, which has become the modern day ritual for all people moving into an unfurnished place; I estimate that this modular masterpiece survived for about three months before it needed some engineering assistance. My engineering lesson came at two in the morning when Austmarka decided that supporting the clothes rail was something of an optional duty. After a week of playing ‘if I…

    24 Apr 2014 | 8:20 am
    Getting your "space legs" in Earth orbit has taken on new meaning for NASA's pioneering Robonaut program. Thanks to a successful launch of the SpaceX-3 flight of the Falcon 9/Dragon capsule on Friday, April 18, the lower limbs for Robonaut 2 (R2) are aboard the International Space Station (ISS). Safely tucked inside the Dragon resupply vehicle, R2's legs are to be attached by a station crew member to Robonaut's torso already on the orbiting outpost.

  • The Enterprise Ethane Terminal Is Quite Large (UPDATED)

    Alex Tullo
    24 Apr 2014 | 8:17 am
    As you may have heard, Enterprise Products Partners plans to build an ethane export terminal in Texas. It will have a capacity of 240,000 barrels of ethane per day. Let’s convert that number from the oil perspective into the petrochemical one. According to John Stekla, formally the olefins guru at IHS and now with Williams Cos., 1 million metric tons of ethylene production consumes about 63,000 barrels per day of ethane. So that means that the Williams facility, IF it ran at full capacity would export enough ethane to feed 3.8 million metric tons of ethylene production. That is more…

    Back in July 2013, the Russian fertilizer maker EuroChem, in a joint press release with Louisiana governor Bobby Jindal, announced it was planning to build a $1.5 billion ammonia and urea complex in Louisiana. At the time, the announcement was just one in a long line of chemical and fertilizer projects meant to take advantage of shale. The project seemed plausible enough. There have been plenty of foreign companies planning large U.S. projects–for example, South Africa’s Sasol, which is working on an ethylene cracker and gas-to-liquids plants in Louisiana.

    University of Durham chemistry professor Kenneth Wade, famously known for the borane electron-counting rule that bears his name, passed away on March 16 at age 81. Chemists at the University of Nottingham, led by big-haired chemistry professor Martyn Poliakoff, have prepared a lovely video tribute to Professor Wade as part of their Periodic Table of Video series. Chemists use electron-counting rules to determine bonding patterns in different classes of compounds, such as the familiar octet rule for first- and second-row elements, the 18-electron rule for transition metals, and the Hückel…

    21 Apr 2014 | 3:11 am
    David Cameron, the United Kingdom's Prime Minister, not only thinks porn is bad for children—he's done something about it.  After calling in a speech last year for a change in online access to adult sites in the UK from "opt-out" to "opt-in", most internet providers were persuaded by Cameron's government to make porn-blocking filters the default option for their customers.  After the change, if an account holder wants to view such sites he or she must actively set the account option to do so.  In promoting this initiative, Cameron's goal was, as he put it, "protecting…

    Engineers are people of action, not just words.  But even if we believe what we are often told about climate change, it's not at all clear what we should do about it.Last week, I attended a meeting at which a highly credentialed professional meteorologist outlined the history of the science of climate change from the nineteenth century to the present.  Prof. Andrew Dessler of Texas A&M's Department of Atmospheric Sciences described how as long ago as the 1890s, Swedish scientist Svante Arrhenius calculated that the small concentration of carbon dioxide in the atmosphere (then…

  • The Ethics of Patents: Patrolling the Patent Trolls

    17 Mar 2014 | 4:17 am
    As most engineers know, the U. S. patent system is intended to protect the inventor's rights in an invention.  A patent holder has exclusive rights to make, sell, or license an invention for a limited period of time (currently 20 years).  This is a compromise between two extremes:  the free-for-all extreme in which no patent law exists and anyone who can figure out an invention can copy it and make it without incurring development costs, and the perpetual-monopoly extreme in which patents would last forever and nobody else could ever make the invention.  Most compromises…

    21 Apr 2014 | 10:52 pm
    Seattle Tunnel Partners released a new schedule this week for the repair of the damaged seals on the Bertha Tunnel Boring Machine. This revised schedule shows that the TBM won't be digging again until March of 2015. The excavation of the pit to access the TBM will begin at the end of May, a delay caused by additional archaeological work. By October they hope to have the cutterhead removed to conduct the repairs, and the machine will undergo testing in February of 2015 with tunneling resuming in March of 2015. [Source: WSDOT.

    This topic was discussed in greater detail in Episode 184 of to The Amp Hour. This article is more about the personal feelings that have accompanied this (ongoing) transition. Starting Friday, for the first time in my adult life I will be without a job; at least a job as I’ve always defined it. I have been employed as a full time electrical engineer (in various roles, the most relevant being analog ones) for 8 years straight. Prior to that I had been working as a co-op for 10-20 hours a week for another 2 years. All told, I would estimate I have worked roughly 17,000 hours up until this…
  • On Education

    Chris Gammell
    28 Dec 2013 | 10:42 am
    I’ve been sour on education lately. Given my entry into the field, I felt it prudent to explain myself. In general, I’ve been well served by my own education. I went to a great public school system where I grew up and I went to Case Western Reserve University (CWRU) for my undergraduate degree in EE (I have neither a Master’s nor PhD). I had decent grades (solid B+ student throughout my tenure) and I had a good experience with my classmates. So what gives? Why do I complain about education? One reason is that the real value that came out of CWRU was the co-op program. It was…

  • Overview of a wake imaging system

    Paul Dvorak

    The schematic is of a stereoscopic PIV setup. Wind turbine wakes lead to lower power production and increased loading on downstream turbines from the reduced incoming velocity and increased turbulence contained within the wakes. Detailed measurement will improve the understanding of the wakes needed to improve wake modeling and consequently support reducing cost of energy (COE) at the plant level. Sandia National Lab is developing a wake-imaging system to provide detailed wake velocity measurement capabilities. The project will demonstrate the viability of measuring the formation and…

  • When is a Stage a Platform in the International Building Code?

    Sean O'Hara

    One of our current projects is the renovation of the gymnasium at the Denver Montclair International School to add a stage at the end of the gymnasium. The stage area is approximately 1,090 square feet. In the International Building Code a “stage” over 1,000 sf triggers a number of requirements for construction including a standpipe, sprinkler systems, fire separations and stage ventilation. What we needed to do was have the stage area properly classified as a “platform” rather than a “stage” which makes many of the requirements go away. The difference in…

It revolutionized our process and saved a lot of material from being scrapped. This engineer was obviously proud of his achievement and wrote a paper on it and applied for a patent. Everyone was envious of him and his accomplishment. That was until he found out the rest of the world had being doing this sort of thing for the last 30 years.

    The way we work is changing. The structured production lines of the factories from decades ago are diminishing. As more tasks are automated and the tools we use become more powerful, the skills required of the engineering workforce in particular is changing. A lot of the work carried out by modern engineers is creative and self-directed. That’s a shift from days gone by where the primary aim of many engineers was to keep the production line running, or at least to design products or components which made use of the factory manufacturing model. Now, we’re not bounded by the shift…

  • How Cybersecurity Is Evolving to Protect Our Energy Grid

    Jerome Farquharson
    24 Apr 2014 | 1:00 pm
    The U.S. power industry was designed to generate and distribute electric power, but the energy grid has evolved since its initial conception and design. Its once mechanical controls have gradually been replaced with digital technologies, computer networks and Internet-driven devices. With each addition, the grid — along with the rest of the nation’s critical infrastructure — grows vulnerable in different ways. The Fight Against Cyberthreats In 2012, then-Homeland Security Secretary Janet Napolitano reported that cybercrime was the No. 1 threat to the United States, ahead of…

    Technologies previously used alone are beginning to converge and collide, with major implications for building design, business and sustainability. According a recent report called “Verge and the Built Environment” from GreenBiz Group, the technological development of the future will be less about linear thinking and assembly line production and more about integration in support of an optimized whole. This is something we see coming true in our own business and with our clients as a whole. According to the report, the catalyst for this integration is the explosion of information and…
  • Technology: Making Environmental Compliance Monitoring Easier and More Effective

    David Smith
    8 Apr 2014 | 7:00 am
    Monitoring environmental compliance is no easy task. A great deal of coordination and information exchange is needed to verify that construction programs adhere to legal standards. In order to effectively monitor environmental compliance, timely and accurate compilation of data is required throughout the execution of large construction programs. As a means of streamlining compliance monitoring, my team and I have implemented a GIS-based system for field collection and reporting of compliance data, which encompasses biological, air quality, water quality, cultural resources, safety and…
  • Rope Access: How Engineers Inspect Bridges

    The Burns &#38; McDonnell Team
    7 Apr 2014 | 4:00 am
    Bridge inspections can create challenges for engineers because parts of the structure are often difficult or costly to reach using traditional methods. Since the mid-1990s though, when an innovative approach was needed after the failure of floodgates on a California dam, climbing and rappelling has been an increasingly useful technique for bridge inspection and repair. When the floodgates on the dam near Folsom, Calif., unexpectedly failed, the owners needed to gain speedy access to the remaining gates to ensure that they weren’t becoming distressed. The problem was that the main structural…
  • Envision Rating System: A Complement to NEPA

    Carrie Barton
    4 Apr 2014 | 1:57 pm
    Both the Envision™ Sustainable Infrastructure Rating System and the National Environmental Policy Act (NEPA) examine project impacts on communities and the environment. NEPA has existed for decades and is federally mandated, while Envision is fairly new to the scene and is completely voluntary. But opportunities exist for these two processes to complement one another and to be mutually beneficial. What Is Envision? First, a little background: Envision provides a framework for evaluating and rating the sustainability of infrastructure projects. It focuses on improving how teams design, build…

  • Self Healing Composites now a Possibility

    John Shury
    17 Apr 2014 | 2:25 am
    Researchers from the Beckman Institute for Advanced Science and Technology have created a 3D vascular system that allows high-performance composite materials like fibreglass to heal autonomously, and repeatedly. Internal damage in fibre-reinforced composite materials is sometimes very difficult to detect and nearly impossible to repair using conventional methods. A small internal crack can quickly grow into de-lamination where the layers can separate, this remains one of the most significant factors limiting more widespread use of composite materials. Led by professors Nancy Sottos, Scott…

    Being Brunel | The Civil Engineering Blog Over the last year I’ve been learning some real practical engineering lessons from the most unlikely of sources: my IKEA Austmarka wardrobe. Brought from that nightmarish trip, which has become the modern day ritual for all people moving into an unfurnished place; I estimate that this modular masterpiece survived for about three months before it needed some engineering assistance. My engineering lesson came at two in the morning when Austmarka decided that supporting the clothes rail was something of an optional duty. After a week of playing ‘if I…

Well, I managed to get in touch with the lecturer (Dr Helmut Pottmann) who has kindly given me permission to share the video with you. Initially I was going to cut it down to highlights, focusing on the structural aspects. But to me the whole thing is so amazing, it seemed a shame to deprive…
