About this Issue….


Welcome to AECWeekly! This week, AECCafe and AECWeekly would like to extend our sympathies to those who have suffered and lost loved ones as a result of the massive destruction wrought by Hurricane Katrina. The absolute destruction of homes and lives cut a swath across the Deep South from Florida through Mississippi and New Orleans, wrecking havoc in yet unimaginable ways. The recovery effort will take time, and will require enormous resources.


New Orleans Mayor C. Ray Nagin stated that he believes New Orleans will not be functional for months. It has been estimated that the total cost of damage may reach upwards of $25 billion. And that is just one city - many others suffered greatly as well.


Oil production in the Gulf of Mexico has been shut down. With the resulting drop in production, gasoline shortages developed in some areas of the country, and prices surged above $3 a gallon. To counteract this rise in prices, the Department of Energy said it would release oil from the nation's strategic reserve to offset the production losses.


Already in the works this week before the hurricane made landfall, was our story on 3D CADD and 3D laser scanning, which is of specific interest to power, process and offshore designers and engineers.


One of the toughest challenges, particularly in the area of process, power and offshore engineering and design, is the issue of retrofitting existing facilities. Since 3D CADD hasn't been around that long, most plants and facilities were built using 2D non-electronic documentation, which may or may not be altogether accurate to begin with. And even if it was accurate when constructed, over time many changes have been made to the facility, typically without updating the as-built documentation. Read about how 3D laser scanning can be used along with 3D CADD to boost productivity and cut costs dramatically in this week's Industry News.

A Hybrid Approach to As-Built Design:
Combining 3D CADD with Laser Scanning
By Susan Smith


Click to Enlarge
For the sake of this article we will be referring to CADD with double “Ds” as in “computer aided design and drafting,” since so much of design engineering is comprised of both drafting and design.


For designing new facilities in recent years, 3D CADD has been an invaluable tool that ensures design standards and best practices are embedded and enforced, thereby making sure the documentation is accurate and consistent. In addition, 3D CADD models have the advantage of being electronically transportable to engineering design teams around the world. Other data, such as facility information, can also be linked with the visual 3D CADD model so it can be easily found. Moreover, construction phase rework is virtually eliminated, which cuts down on costs and schedule delays.


But 3D CADD can't be used for everything today. One of the toughest challenges, particularly in the area of process, power and offshore engineering and design, is the issue of retrofitting existing facilities. Since 3D CADD hasn't been around that long, most plants and facilities were built using 2D non-electronic documentation, which may or may not be altogether accurate to begin with. And even if it was accurate when constructed, over time many changes have been made to the facility, typically without updating the as-built documentation.


Further, even if electronic 2D documentation was available, a 3D model cannot be easily generated from traditional 2D CADD. Therefore, creating a 3D CADD model for an existing facility requires time-consuming manual modeling. Even if 3D CADD models are available, they can be inaccurate or incomplete as they typically use idealized representations of space and features, assuming all angles are 90-degrees. Additionally, details such as gusset plates, packaged equipment, field routed utility systems, instrument conduit and cabling are usually omitted. It is these “real-world” imperfections and details that cause the majority of construction rework..


So, it's understandable why contractors are more excited about a new building opportunity than a revamp. On the other end of the spectrum, project managers are tasked to control project costs while being challenged with unknown rework costs on maintenance and modification projects that may or not be budgeted in the original estimate. To avoid these issues, the re-creation of as-built data should occur early in the project lifecycle so that reliable information is available from the beginning of the project.


Collecting As-built Data


Click to Enlarge
One way to gather as-built data that has gained popularity within the past few years that does not require manual remodeling is laser scanning. One laser scan is composed of millions of individual 3D spatial measurement points that can be viewed as photo-realistic 2D images. The key word here is viewed - each point in the “3D laser model” offers the user a highly accurate physical measurement of a point in 3D space. There is no difference between the measurement points on the surfaces of objects such as pipes, vessels, steel or concrete, so those points do not possess “attributes” as they might in 3D CADD. The 3D laser model looks like what it is - a “digitized
plant.”


Once the as-built laser scan data has been collected, it can be combined with 3D CADD models to provide the existing plant conditions for design and create entities in the 3D CADD package. It can also be used to take measurements from point to point and find details such as pipe centerline, angle and outer diameter, for example. When dealing with existing structures, this allows for only those parts of the structure that need work to be remodeled, rather than having to remodel the entire structure.



Other Procedures


Click to Enlarge
3D CADD models can also be imported and displayed within the 3D laser model for visualizing proposed modifications for design and constructability planning, to compare and validate CADD models against the as-built laser documentation, and to share proposed updates with project team members who aren't CADD software users.


As in 3D mechanical models, these 3D CADD models can be clashed against the 3D laser model to see if there are potential interferences or dimensional “busts.” This way, potential design clashes can be identified and eliminated early on in the design process, before they find their way to construction.


3D laser models can also pick up features such as packaged equipment details, field routed utility systems, and instrument conduit and cabling where they are visible and provide accurate dimensions. This helps ensure that clashes against even the smallest plant details are identified and eliminated as well as assists with the routing of new pipe, conduit, etc.


One of the other great features is that it is possible to scan plant structures safely, even in areas that are hard to see or are congested, where actual physical access would be dangerous or impossible. In this way, the use of 3D laser modeling also eliminates the need to put large numbers of team members in jeopardy of exposure to hazardous conditions.


Some 3D laser scanning companies, like
Quantapoint, have a team of CAD personnel that use their 3D laser scanning data to create 2D drawings. Quantapoint is unique in that they offer “integrated laser scanning,” which means they use their own hardware and PRISM 3D software. This enables them to guarantee the accuracy of the results by, for example, ensuring calibration of the equipment. “One of the secrets of the industry is that if the laser scanner is not calibrated prior to usage and it is off by a even a small degree, it can result in an inch or two error in measurements that are 60 feet away. There is no such this as 'self-calibrating' hardware. We build the hardware, so we know its capabilities. We have a dedicated lab in which we calibrate it prior to every project, then we check calibration regularly in the field and when we get it back,” explained James McGill, Vice-President of Marketing. “Our PRISM 3D software not only lets you view and share the 2D laser scans and share them across, but also extract dimensions as an x,y,z coordinate since each pixel is actually represents an absolute distance in space. You can also measure outer diameters of pipes, distances between two beams, take slices of data and actually export them to AutoCAD, create isometrics, etc.” The company has created over 25,000 drawings for
their customers.


The process of 3D laser scanning also requires that field crews who go out on site be fully trained in safety and how to do laser scanning itself. “It's different than doing regular surveying, i.e.,” McGill explained. “When I take multiple scans, I have to ensure that I include three to five targets across each scan so I can link those together. Integrating the data is called registering or networking the data together. If I were to use traditional surveying between each laser scan, I would propagate errors across them. If each survey were only off 1/4 inch, that could mean a 2 inch error between laser scan 1 and laser scan 200. Quantapoint's patent-pending integration
technique ensures no worse than 1/4 inch uncertainty across all laser scans, from any point to any other point.” What Quantapoint delivers is complete as-built laser documentation that can include the 2D laser scans, 3D laser models and 2D drawings.



Benefits


Click to Enlarge
Clearly there is a lot to be gained by combining 3D laser models with 3D CADD models. Listed below are some of those benefits:


Reduced costs
  • Costs associated with project rework and field fit-up welds are minimized.
  • Global engineering centers can be leveraged as the digitized plant can be easily shared.
  • Lost revenue from not meeting shut-down and turnaround schedules is avoided.
  • Optimized schedules
  • Time spent in plants collecting data is greatly reduced.
  • Design efficiency is greatly improved by using as-built laser documentation directly with CADD models
  • More components can be prefabricated with greater confidence, knowing that they will fit.
  • Shut down and turnaround durations are minimized due to less project rework and field fit-up welds.
  • Increased quality
  • Improved sharing of more accurate information reduces many of the risks associated with project execution.
  • Accurate and detailed information improves engineering designs and many of the decisions that affect construction and start up.
  • More accurate design and constructability reviews are possible from combining 3D CADD and 3D laser models.
  • Projects that were once viable only in 2D drawing tools can now be executed using 3D CADD.
  • Improved safety
  • The number of people required for plant data collection tasks and the duration of time spent in the plant are dramatically reduced.
  • Rework is minimized because fit-up can be confirmed by analyzing the scanned data and prefabrication can be maximized.
  • Exposing large numbers of project team members to hazardous conditions is minimized.
  • The combination of 3D CADD and 3D laser models is a powerful tool, making it cost effective to use 3D CADD design technologies for revamp projects. The facility can be any age, the available design documentation can be any format and incomplete, the project can be of any size, and the design team can be located anywhere in the world. This helps reduce the risk of project rework tied to dimensional and interference busts and make a compelling case for adopting laser scanning in any revamp project.

    Looking for Loved Ones


    So many people are missing in the affected areas, that several people have opened up websites or added sections to websites dedicated to the posting of messages for missing loved ones.
    Craigslist.com, a Web site better known as a place to buy or sell or rent, or look for love, is now flooded with posts looking for the missing.


    Here's a positive one: “Just heard from my sister. She is OK!!! She had slight damage to her house (shingles off), lost 30 trees on her property, but horses, dogs, and my sister are OK!!! She had to drive 30 miles to a pay phone.”


    The Times-Picayune newspaper
    site has a “Submit your own Stories” section that is now filled with notes from people looking for others. The paper also has created a new category for those people needing rescue.


    "Please help," one read. "About 400-500 people are gathered at the church on 5069 Willowbrook Drive, 70129 ZIP and are waiting for help. They have no food and water is rising. Please help."

    A new web site called
    findkatrina.com is dedicated to finding the missing.



    Press Coverage and How to Help


    The
    Times-Picayune website, featuring “Everything New Orleans,” also has maps, satellite images, alerts, photos. Also people are encouraged to submit their own stories. According to
    The New York Times, the Times-Picayune, whose daily circulation is 270,000, put out only an electronic edition on Wednesday with a one-word headline summing up the impact of Hurricane Katrina: "Catastrophic." The local paper is like other news media outlets in New Orleans that mostly abandoned newsprint and television broadcasts on Wednesday and set up shop on the Web.
