Sherborne Sensors’ Mike Baker examines how field-proven sensor technology lies at the heart of Structural Health Monitoring (SHM) innovation.
Structural Health Monitoring (SHM) is an emerging field that provides information on demand about any significant change or damage occurring in a structure. It has been employed for many years in civil infrastructure in various forms, ranging from visual observation and assessment of structural condition, to technology-led approaches involving deployment of an array of sensors that can include accelerometers, inclinometers and strain measurement devices on site. These sensors can be deployed on a permanent basis or moved on and off site each time a fresh set of data is required.
Conventional forms of inspection and monitoring are only as good as their ability to uncover potential issues in a timely manner. One of the major difficulties with SHM instruments for example, is managing the huge volumes of data that sensor arrays generate. Meanwhile, visual inspections and evaluations are insufficient for determining the structural adequacy of bridges or buildings.
Brian Robins, director of business development for managed services at Bentley Systems, talked recently with AECCafe Voice about Bentley MANAGEservices, their solution to provision, manage, monitor, and support Bentley software solutions for architecture, engineering, and construction. “Managed services were quite popular in the 80s and 90s and then got overlooked,” said Robins. “Now they are coming to the forefront again, for several reasons.”
Sefaira today announced that its performance based design platform includes daylighting analysis in their Sefaira for SketchUp product. With the addition of daylighting, Sefaira combines two critical design metrics in the same tool.
The number of large scale construction projects that are implementing building information modeling for collaboration, integrated project delivery and lifecycle management is growing all the time.
First Place Winner of Autodesk’s Excellence in Infrastructure – Denver International Airport ExpansionFriday, January 31st, 2014
The 1st Place Winner from Autodesk’s Excellence in Infrastructure Competition this past fall was HNTB, for the Expansion of Denver International Airport, originally built in 1995. The project was started in 2008-09, and includes 519-room hotel, a rail line from downtown to a hotel, which was part of the original master plan of the airport when it was originally built. The expansion includes the integration of a rail line, new baggage handling system, and the new airport is being prefabbed with a new entry way, security checkpoints, baggage screening – all of that being developed with the hotel.
Denver International Airport embodies an “airport city” concept.
“You can see where the rail line comes in and the glass wave shape at the top is the new hotel project,” said Eddy Krygiel, architect at HNTB. “It’s all attaching to the south side of the airport. We moved over 1 million cubic feet of earth in excavation.”
Eric Carpenter of Rand Secure Data, a division of Rand Worldwide, the parent of IMAGINiT, talked recently at Autodesk University about secure archiving of data and the increased need for AEC solutions in this field. Secure archiving of data has been prevalent in the enterprise of banking and other industries. AEC is now subject to increasingly external regulations, and data must be regulated carefully. Changes to the Federal Rules of Civil Procedure (FRCP) have stressed that proper management of electronically stored information is essential when working with partners and multiple internal departments on a project. The size and special requirements of data such as point cloud data and files related to each other such as occur in a BIM model have to be taken into consideration. In response to this need, Rand Secure Data has released a comprehensive the Data Governance Solution that provides AEC firms with the tools for eDiscovery, email backup and archiving.
“An example is Newforma for point cloud data, it only shares what the users have time to enter. With our Data Governance Solution, it captures all the information and catalogues it. It also compresses data down to a fraction and uses Rand’s Data Center to store it,” said Carpenter.
Josh Lowe, senior innovation advisor and Mike Whaley, president of TURIS Systems,spoke at Autodesk University during the session entitled, “BuildX: Construction Site of the Future.” Lowe and Whaley talked about the scanning revolution, or “reality capture” as it is now called. TURIS develops and implements project-specific Building Innovation Systems that utilize a technology-based modular approach for knowledge management. Laser scanning or reality capture has become more accessible, portable and more applicable.
Last year’s predictions for the year, Top AEC Predictions for 2013 – AECCafe Voice, were somewhat different from this year’s. Although those predictions are still useful to note this year, I am focusing on some product directions and initiatives since there is a continuing, pressing need to address critical infrastructure, fueled largely by climate change, greenhouse gas emissions, and failing infrastructure and economy. Products developed and industries becoming more collaborative all shape the predictions of the year 2014.
In a session held at Autodesk University 2013, entitled “BuildX: Construction Site of the Future,” the future of building was explored by industry experts.
Senior vice president, Building Information Modeling, Amar Hanspal, said that construction employs the most number of people around the world (with the exception of health care). $7 trillion is tied up in the world of construction.
Iconic buildings are built in much the same way as they have always been built. Examples are the Empire State in 30s the Gherkin recently. They are labor intensive, and involve masses of blueprints. “Over the last 80 years, the jobsite hasn’t changed dramatically,” said Hanspal. “We may talk about design and engineering changing, but the world of construction has more evolution to do.”
He added that the economists bash this industry a bit. “Every industry except construction has increased in productivity in the past fifty years.”
Construction companies are very pragmatic, yet they were the earliest adopters of cell phones, for people on jobsites. All GPS systems and location systems have been used in construction.
How does someone manage complex logistic in construction process?
Hannu Lindberg,Technology Manager, VPR Construction, talked on the topic, “Managing a Construction Supply Chain and Quality.”
“We’re seeing more schedules, and witnessing prefab and modular assemblies, which are becoming critical to projects,” said Lindberg.
This process is required to deliver product much earlier on, but also opens up possibilities to track these components much earlier on in the supply chain process.
Lindberg said “Lightspeed is too slow. We’ll have to go to right to ludicruous speed. We’re beginning to fabricate more products off site in order to make lead times. We want to install building blocks as they arrive onsite.”
Global sourcing materials are becoming global as well. “We have a process in place and have procurement lead time earlier in process. Parts are being brought from various parts of the world, preassembled in the factory, tagged with a barcode, put in storage, then delivered to the site.”
What if we integrated quality process into the process? Asks Lindberg. At the factory level QA inspections? “There is currently no transparency into that process from the perspective of the general contractor. If we build checkpoints for quality throughout the supply chain, starting at manufacturing level, with checking and enforcing this quality, the chances of poor quality showing up on jobsite is significantly lower.”
The system is still primarily paper-based. To improve communications between the subcontractors and the general contractor we can replace paper based systems with mobile, barcode scanners, and all the technology to simplify and improve the process.
