The office building at the Navy Yard’s Corporate Center in Philadelphia, is intrepid in address and in nature. Located at 1200 Intrepid Avenue, the master-planned development within the Navy Yard is constructed entirely of flat concrete planks.
This is easy for the three sides of the structure that are conventional flat walls. Not so much for the east façade, which is designed to resemble the curve of the ships docked in the nearby Navy Yard. This side has a variety of radii, ranging from 97.5 meters (320 feet) at the ground floor, to just over 2.7 kilometres (8 900 feet) at the parapet of the roof. Each concrete plank is set at an angle so the composition gradually becomes a curving wall with mesmerising optical effects.
The flowing and curved shape of the Intrepid building required significant cantilevering and structural load analysis, with the curving façade tilting outwards as much as 23.56 degrees. Not to mention the safety backup connections that were required to prevent a progressive collapse, if one connection should fail.
A daunting task for any precast concrete company. But possibly less so for High Concrete Group, an avid adopter of 3D modelling, who have been using constructible models to LOD 400 (Level of Development).
“We couldn’t have done the Intrepid project in 2D,” said Dave Bosh, Design Team Leader, High Concrete Group. “Tekla Structures made a significant impact on our success by allowing us to collaborate, save time, reduce costs and work efficiently with all of the project stakeholders.”
Designing, fabricating and installing the necessary plumbing systems for the Liberty Center, a mixed-use development in Ohio, USA, at first sight seemed an ordinary project. However, two of the mixed-use buildings include a ground level and first floor elevated post-tensioned slab with post-tensioned cables. This meant there could be no core drilling or slab cutting once the deck was poured.
Jim Mercer, commercial project manager for Ken Neyer Plumbing, one of the top speciality contractors in the region, and the company tasked with this project, explains the challenge.
“We knew we couldn’t layout the sleeves and hangers using the conventional methods of pulling tapes because locating walls at that angle would have been impossible. If we couldn’t find a way to do it ourselves, we would have to hire a surveyor or civil engineer to mark out the walls and penetrations. We also had a very aggressive pour schedule. Building H had five pours – one per week – for the post-tensioned slab while Building C had four pours per week for its post-tensioned slab. So getting a surveyor to do it would have been very difficult with scheduling.”
Fortunately, Jim had recently heard about prefabrication tools linked to robotic total station technology and after some evaluation selected the Trimble Field Link for MEP layout solutions.
An update to Prolog has been released with enhancements based on user feedback.
Prolog 9.95 includes updates to the running of the program, including a “forgot password” feature, the ability to include attachments in notifications.
Prolog has also been streamlined with images now able to be included in safety reports, punch lists and issues, instead of being separate file. And attachments now able to be included to notifications, instead of logging into the system. This makes it easier to the information you need to get your job done.

Did you know that Moddex has launched the first range of Tekla tools to help users easily model large runs of handrail for their Tuffrail system?
Fast and easy to use Tekla handrail components insert with two clicks from end to end. They will auto bolt to all beams, output all the correct part codes. They also have all desired options for
floor or side mounted
sloped stair rails
one, two or three rails
base fixing types
They will also be included in the default handrail drawing template and come with their own Tekla Excel report which will output all the correct handrail codes based on what options were selected for the post types.
The Moddex Tuffrail System for Handrail Tools is available as a free download for Tekla users from the Tekla Warehouse.
Trimble recently announced an upgrade to their field and office collaboration tool, ProjectSight.
This update includes a brand new module, Daily Reports, which may be used to track daily activities such as Labour, Weather, Comments, Photos, and Links to other records.
In addition, there are several improvements to the Drawings area. These include the ability to filter annotations using a new Layers panel, automatic annotation labels for linked records, and a new summary log report.
To help you get the constructible model from the office to the field, Trimble has designed the Trimble Kenai Rugged Tablet Computer.
Built to withstand the daily abuse of construction work, it meets military standards for drops, vibration and humidity; and is protected against dust and water. The full-colour, ten-inch screen is scratch and impact resistant and enhances sunlight readability for outside work. A multi-touch, gesture-controlled touchscreen allows users to type, pan, and zoom with fingers, a stylus or capacitive gloves.
The Kenai works with Trimble Field Link and a Robotic Total Station, the Trimble Rapid Positioning System, or even a Trimble R8s GNSS receiver in the field. (Learn more.)
Most structural steel companies aren’t using BIM to its full potential. Are you one of them?
3D models were first used to make drawing production easier, but these days, information rich models are the key to better productivity throughout intelligent steel fabrication. However, many of the benefits of building information modelling remain untapped Using the entire model opens up a world of possibilities, beginning with design.
Tekla have provided a free eBook to help you optimise your workflow, get more out of BIM, and make your projects as profitable as they should be.
Did you know that the Custom Inquiry Tool is new and improved in version 2017? It allows you to view specific information based on your current workflow and speed up your workflow. Check out specific data like Assembly Position, Part Position, Weigh, Phase, etc. that you want to see quickly without having to do multiple clicks or scrolls.
In the four minute video below Lee Snyder, product manager for the steel segment at Trimble, gives us an overview of the Custom Inquiry Tool.
The latest release, R6.5, to Vico Office includes enhancements to benefit the workflows of design, cost and time-management.
Design Workflows have been improved via the introduction of rebar takeoff support for Tekla models. Users can now publish their detailed concrete models into Vico Office and get full quantity analysis and change management capabilities on rebar models. Additionally, users will be pleased to experience even more 3D performance enhancements to help support the increasingly larger models that come with support of such high volume elements.
Further improvements to support the design workflow include the support of BCF integration for communicating constructability issues outside of the Vico Office application.
Cost Workflows now have new features, including conditional formatting of data and the ability to bring parent hierarchies from a reference estimate.
Both changes will make working in cost planner for long durations easier, as hierarchy adjustments will automate estimate creation and conditional formatting has the ability to draw user’s attention to specific data within the estimate.
New features to Time Planning Workflows include the ability to create tasks without cost components. As well as a significant increase in the amount of production control data to web services for an increased ability to do analytics tracking around install performance data.
Model-based schedules are now easier and quicker to create, with the production control information available to anyone who has a web connection.
Working on the latest version allows you to stay ahead of the pack with the latest features and functions.
