Executing a Mammoth BIM Implementation with the Help of Trusted 2D to 3D Processes and Student Manpower!
This blog is part four in a series that discusses the challenges and process involved in implementing BIM at The Ohio State University Wexner Medical Center, a project which saw the team win the 2011 [acronym] Magazine Public Sector CAD Award.
Phase 1: Big Bang Implementation
Following the all important completion of Phase 0, we were ready to kick off the actual work of developing Revit-based building information models from our AutoCAD floor plans. In June of 2011, the implementation process started with two undergraduate architecture students and two graduate architecture students from the Knowlton School of Architecture, along with one undergraduate civil engineering student, all from The Ohio State University. While their first week included on-site orientation, team building and a project overview, the students quickly became acclimated with the technology they would become expert at during a focused three day training session on Revit Architecture.
This highly customized training, led by Brian Skripac from DesignGroup, was a product of the Standards and Process Development effort and focused on the execution of the newly defined process map and workflow integrations to translate information from 2D to 3D. The students were not only taught how to use Revit Architecture but it was presented in a way that would mimic their everyday use of the software as they began to model the existing facilities. Another benefit to this effort was that the project team was exposed to the wealth of newly created content and “kicked the tires” on how well our processes worked. This allowed us to improve and refine our process to the benefit of the project as a whole. As the training concluded, the students were immediately assigned a building and began the process of developing their first model.
Phase 1 included the development of a basic BIM intended to capture the following elements:
By the end of the summer, the students logged 2,750 hours, primarily engaged in the model development process. Our calculated metrics indicated we should have been done with the bulk of modeling effort by this point, but we had only completed about 77% of our buildings, by space.
One of the several factors that increased the amount of time - to accomplish Phase 1, was the students desire to add more detail than we initially planned during Phase 1. The result of this increased detail was more valuable models. This affected several aspects of Phase 1:

Phase 1 included the development of a basic BIM intended to capture the following elements:
- Basic Exterior Wall Construction
- Interior Walls & Cubicles
- Doors & Windows
- Basic Roofs
- Basic Plumbing Fixtures
- Columns & Column Grids
- Basic Floors & Ceilings
- Basic Stairs
- Rooms & Areas
By the end of the summer, the students logged 2,750 hours, primarily engaged in the model development process. Our calculated metrics indicated we should have been done with the bulk of modeling effort by this point, but we had only completed about 77% of our buildings, by space.
One of the several factors that increased the amount of time - to accomplish Phase 1, was the students desire to add more detail than we initially planned during Phase 1. The result of this increased detail was more valuable models. This affected several aspects of Phase 1:
- Instead of using basic windows, most of the BIMs included detailed window families.
- The exterior wall construction was accurately reflected, and almost all exterior facing wall details were visualized.
- A higher level of focus on accuracy than expected, meaning more time tracking down documentation and performing field verifications.
- Engineering and Operations: A three day session covering how to navigate/interact with a Revit model and how to extract information from the model.
- Interior Designers and Space Planners: A four day session covering everything from scheduling to views to moving walls and placing families, along with how to create renderings and walkthroughs.
- Construction Managers: A half-day session on navigating DWF versions of the Revit model in Autodesk Design Review.
- Energy Engineering: A two day session on how to translate the existing Revit models as gbXML files for their use in tools like Autodesk Green Building Studio and eQUEST.

Transition periods are never easy. As businesses move from routine practices to uncertain situations, there’s a level of trepidation involved. Thankfully, there are ways to ease this anxiety—namely, by shedding light on the gap in old vs. new practices. At a time when many organizations are either in the middle of transition or running up against it, investment in visibility is imperative.
Nowhere is visibility more important than facility planning. Facility managers need oversight as they begin to adapt assets and workflows in the near-term and for the future.

The COVID-19 pandemic has been disruptive to physical workplaces for so many reasons. One of the biggest challenges for businesses has been adapting offices to new and often equally disruptive safety standards – social distancing, sanitization, contact tracing, etc. While there’s keen emphasis on these practices, indoor air quality (IAQ) in many offices is only now getting the attention it deserves.

Healthcare facility management is complex, especially since many organizations are open around the clock. Ensuring yours is at its best is expensive. Maintaining a building properly accounts for more than 80 percent of the total cost of operations and occupancy. Safety regulations constantly change. Patients arrive and depart on a variety of timelines. Healthcare workers regularly use spaces like break rooms and storage areas.

Does your business have a single source of truth when it comes to data sharing across facilities? Ensuring data is accurate, relevant, and structured is something any business can recognize as important, yet it is more difficult to achieve than most realize. Just because you are use an integrated workplace management system (IWMS) or have relevant GIS data doesn’t mean it provides a single source of truth.

Prior to 3D printing’s arrival on the manufacturing scene, the US military supply chain was often met with lengthy and arduous timelines for critical asset production. This not only stalled the manufacture and repair of essential equipment within the military supply chain, but it also impeded military readiness, and with high price tags to boot.

Americans spend about 90% of their time indoors, according to EPA reports. Whether it is their home, workplace, or another location, people depend heavily on a controlled environment. Everything from the air we breathe to the light we bask in is artificial or at least managed. In shared spaces, it is the responsibility of building owners and managers to provide healthy and safe workplaces.

Out of sight, out of mind. It’s all too easy to forget about asset maintenance when the assets themselves aren’t right in front of you. During the COVID-19 pandemic, this became more evident as employees went home and logged into a virtual workplace instead of coming to a physical space.

There are two distinct factions when it comes to working from home: those who relish it and those who despise it. Before COVID-19, working from home was a perk. When the pandemic hit, work-from-home (WFH) became a necessity to combat the virus’s spread. One person’s dream; the other’s nightmare.
As COVID-19 rolls on, employers are dealing with two sides of a war between those who want to return to the office and those who’d prefer working from home. Depending on who you ask, results are mixed:

The modern workplace is a far cry from spaces of the past. Banks of private offices gave way to an open concept fad that’s morphed into a hybrid of spaces, including personal desks surrounded by pony walls, hot and hotel desks, and collaboration areas.
COVID-19 threw workplace and space management into turmoil, but the return-to-work movement is underway. As employees come back to offices, stores, factories, and other businesses, the need for privacy in the workplace again takes center stage.

Mixed-use spaces – used by public sector agencies for different purposes – or even mixed-use cities present unique challenges for workplace managers under the cloud of COVID. Unlike single-use facilities, mixed-use spaces may see much larger groups of people come and go. Monitoring the health of every individual is likely impossible without strict contact tracing standards.

Historic buildings hold a special place in the hearts of architects, workplace planners, and employees. There’s something alluring about creating workspaces within the confines of century-old stone or retrofitting a Victorian Era home into offices.
For all their uniqueness, repurposing historic buildings for modern workplaces isn’t as easy as replacing a few light fixtures and brushing on a new coat of paint. Most older structures are governed by sometimes-strict regulations overseen by historic districts – the first was created in South Carolina in 1931.

One of the many challenges that organizations faced this year was the scaling of a remote work model. But with the prospect of life and work returning to normal in the coming months, those same organizations face a new challenge – scaling back up their facilities in a safe way.

The benefits of the Internet of Things (IoT) are undeniable. IoT-enabled technologies collect data that impacts cost, productivity, compliance, and security. However, that data is only as good as the analyses derived from it, especially when it’s connected to how workplaces are populated, and space is managed today and in the future.

Managing real estate for a single workplace is, in certain ways, simple. There is a single set of data for land, buildings, and leases. For companies with multiple properties or a global presence, the task becomes daunting.
A centralized data repository is the key to maintaining accurate and easily accessible information to manage real estate portfolios. But not all data systems are alike. Real estate planners and facility managers should consider several items when choosing a real estate portfolio management system:

Let’s face it: the days of open offices are over. The pandemic likely drove the final nail in the coffin of a design fad that was all the rage but fails to meet the safety and productivity needs of today’s workplaces.
That’s no easy task in the face of a pandemic that shut the economy down for months and continues to wreak havoc. But employers are reopening workplace doors and welcoming employees back—and Archibus is ready to help with safe back-to-work transitions.

The future of government offices, buildings, and installations is about to change dramatically. When workers return to work or building owners make changes to how they work, they can expect offices to be designed differently to minimize the spread of germs and make people feel safe. But we can also expect sanitation to step up significantly.

Digital design data is a big data business. It requires secure management and storage, versions need to be stringently controlled, and teams need to access files readily so they can share that data with stakeholders.
For too long, however, designers, engineers, and CAD managers have relied on traditional document management systems, like network drives, to achieve this. While they do a great job with office documents, those same solutions don’t work well with today’s design files and models, for several reasons:

If you’ve made the move from AutoCAD to Revit, congratulations. But what do you do with that huge library of details that you amassed over years of working on CAD projects? As you transition to Revit, recreating AutoCAD details is a hassle and trashing them is out of the question.
The good news is, you can use details right in your Revit project – straight from AutoCAD.

If your job involves capturing existing field conditions as part of the design and construction process, you’ll know it’s a tedious, manual, often analog and inaccurate process, which often leads to costly re-work.
Whether you’re renovating a building or involved in a large-scale infrastructure project, the process goes something like this:

As any surveyor or field engineer knows, capturing existing field conditions for an infrastructure project or building renovation is a tedious, manual, often analog, and inaccurate process – not to mention dangerous.
Renovations projects are a particular challenge since the infrastructure or building may be decades old and designed before the age of digital blueprints. You’re almost guaranteed to start a project using static 2D image documentation of existing conditions. Verifying and updating these manually is a lot of leg work.

Building information modeling (BIM) is poised for greater adoption by federal, state, and local government agencies. In Wisconsin, for example, publicly-funded projects over $5 million are required to incorporate BIM and 3D software from initial planning concepts to bidding documents and project closeout. Many DoTs, including MassDOT, FDOT, and CALTRANS are also embracing BIM for infrastructure projects.

It’s hard to imagine a world without digital. But as you look around you, much of the physical world was designed and constructed using traditional 2D blueprints and is yet to be captured in a digital format. This creates a challenge for AEC professionals to incorporate these as-built designs into re-build or renovation projects.
Traditional imaging techniques like photogrammetry aided in this process by allowing engineers to piece together photographs of as-built conditions and weave in GPS coordinates to create interactive 3D models, see below:

For government organizations and municipalities, ensuring everyone is on the same page in terms of core competencies is an essential prerequisite to the success of any digital design or engineering project. With the pressure to do more with less, knowledge gaps can stymie team productivity, lower your return on investment in software tools, and make everyone’s lives a lot more difficult.
