Term Project Description

For my term project, I have chosen to create a fully functioning Revit model of a sustainable elementary school. This model will coincide with my senior design project, which is a submission to the ASCE Charles Pankow Foundation Annual Architectural Engineering Student Competition. Each year, the competition assigns a building with a slew of specifications. This year, the building must be an elementary school located in Reading, PA. The school must encompass several features including a green roof, a pool, community spaces, classrooms, offices, restrooms, a kitchen, a nurses office, a library, as well as an art classroom. My senior design team's interpretation of this project is to create a school that will be both energy efficient and sustainable, and a school that will adapt easily to the future demands of education.

Considering that I have previous experience with Revit, I thought that this would be a nice challenge in expanding my knowledge of the software. I believe that having a functioning model will also enhance my team's final design and presentation for the competition as well as for Drexel's senior design experience. My project differs from many other students in the sense that it is directly related to the capabilities of BIM technologies. However I feel that students such as Gabrielle, who are touching on the intelligent versus green projects will correlate to my project in a larger sense.

The specific challenges that I am hoping to address are:

-To create fully functioning "spaces" within the building which will give various data to a schedule which encompasses items such as: occupancy per room, area, volume, etc.

-To have several "model rooms" which are fit out completely with architectural and engineering components. Including finished architectural surfaces, furniture, mechanical systems, plumbing systems, and electrical systems.

-To add functioning mechanical components, which calculate items such as flow.

-To add landscaping features, as well as the green roofs that are required by the competition.

Hopefully the elements that I plan to add to the building information model will aid in helping me to gain a better understanding of Revit MEP and Revit Architecture software.

Future Look - BIM for Owners and Facility Managers

A difference I noticed between the 2008 and 2011 editions of the BIM handbook was that in 2008 the handbook focused on the benefits of 3D drafting, while the 2011 edition focused much more on the benefits of 3D drafting for an integrative design process. In 2008, all disciplines could make separate models and eventually bring them together to form a cohesive design. Now, and in the 2011 version, it is possible for all disciplines to work together from the beginning of the design process using BIM.

This version of the handbook introduced the concept of Integrated Project Delivery. A difference this poses for owners is that they are now responsible for specifying the required scope and level of detail they want for a project before design begins. The design process is now changing in that multiple people are working on a design at the same time, which poses new legal issues concerning responsibility. As Kayleigh stated in her post, "the development of standards is a pivotal and important step in creating a cohesive use of the new method." Owners must understand and be able to communicate in BIM terms exactly what they want from their architects, engineers, and contractors, who will be responsible for what, and when. Like what Eric talked about in class last Tuesday, each project is unique and requires the owner to create BIM standards for every project.

Right now it seems that we have the technology to create fully integrated models between all disciplines but we do not have the proper space or memory to create files that large. On page 188 in the 2011 Handbook it states, “two to five years ago the creation of an integrated model required extensive effort on the part of a project team and dedicated technical expertise to support the integration. Today, many of BIM design tools have matured and provide integration capabilities between several disciplines at the generic object level. “ It seems that most members of my group agree that in the future, companies will have IT departments specifically there for BIM support to help address these issues.  With these advances, we also see performance issues with this technology. Within the next ten to fifteen years, I imagine this space to become accessible, and the norm will be for project design to be fully integrative from the beginning design stages. 

The Future of BIM Interoperability

I agree with Nathan that BIM will be integrated into the construction process regardless of problems with information transfer. While interoperability is admittedly a difficult and unavoidable problem in the current push for BIM as the industry standard for transfer of design information, I see some hope for improvement in the near future.

Within the next 5 years, it is my opinion that interoperability among programs within a specific software provider's repertoire (for instance, all Autodesk products) will improve to the point of near fluidity, so that there is even transfer to a central database of all aspects in a model. (This is one example of such a case in recent history) As Mr. Kuszewski discussed "saving to central" and "cloud-based computing" last week, it became evident that this level of capability is certainly present and need only be implemented across all products in a process known to the scholarly community as "data alignment." In essence, it is merely a process of organization and intentional consistency within a software group to facilitate interoperability and eliminate data loss between products/software-types.

However, in the same time period, I would not be surprised if the chasm of interoperability between competing software groups (ie. Autodesk vs. Bentley) widened. From the previous week's research, it seems like the degree of difficulty in information transfer is directly linked to the depth of information contained in a model. For instance, 2-D CAD models can very simply be converted to an open format, while 4 and even 5 dimensional models in Revit may contain a large amount of information about the individual building members that cannot be transferred cleanly to any other format than that in which they were created. By this line of reasoning, increasing capabilities of competing software types may likely complicate the transfer of data between them.

The solution to this un-interoperability, as Elda describes so well, might just be push for the IFC file format as a required standard. Despite many designer's aversion to this file type, it seems that on a global level, the IFC format is encouraged because it is an open source file type. The capabilities of design using this format are not as limited as one would think, and it certainly appears that they are improving. The Build Qatar event in 2012 was a great showcase of these capabilities.

Week 4: The Future of BIM

I believe that BIM in the future will become the benchmark for the construction industry and will be the standard form of managing the critical design information of a building or any design project at hand.

When researching the future of BIM, I came across video I liked that was posted to www.archdaily.com featuring Patrick MacLeamy, Chief Executive Officer of HOK, and his description of the uses of BIM both now and in the future of projects to come. In summary, MacLeamy comes up with the mega acronym of “BIM-BAM-BOOM” to describe the various aspects of a construction project that BIM has come to be used for and can, when used correctly, optimize all facets of a building project. The original building design is supported by BIM and its ability to develop and test different design ideas. After designing, contractors use BIM as a Building Assembly Model or “BAM” allowing better scheduling and the facilitation of subcontractor coordination and cost control. Finally, over the lifetime of a building an owner can use BIM and BAM to optimize the building’s operation. In this stage of a project, the owner can put benefit by using BIM as a Building Operation Optimization Model or “BOOM” to manage the energy consumption of the building and schedule maintenance in an orderly fashion.

With this mindset, the use of BIM in the construction industry is almost limitless in its uses and becomes an ongoing method of optimization for a building as a whole. BIM has already come quite far in the construction industry and has become a very useful tool that continues to seek improvement to better serve its users’ needs. For this reason, I see BIM continuing to strive and becoming a crucial part of any and all construction projects.

I found my peer Lorena Alvarado's post this week (http://ae-510-ay12-13.blogspot.com/2013/01/bim-in-future_29.html) to be very interesting and have some key important statistical facts. As she mentioned, one of the main concerns of BIM at this current time is the "learning curve" and the training necessary for companies to efficiently make use of BIM programs. However, the increase from 43% (in 2008) to 60% (now in 2013) of architects in the United States using BIM shines a light of hope for the future and is proof that BIM will only move forward from here.

BIM in the Future

To this day, BIM has been very successful with its users and many companies benefit from it daily.  With this being said, we can expect great things in the future.  Considering the importance of data management throughout project constructions, BIM generates the data from beginning to end and from multiple users.  As an effective source of communication, BIM can solve many problems to clients as everything is made available to them.  An obstacle that exists nowadays is the fact that some people don’t know of the existence of BIM and don’t fully understand its advantages.  There will always be the people who don’t like change and are used to the way they have done it for some may years, call it the “old-fashion” way, and feel like there is no need to bring in anything new and ‘complicated’.  Due to this and in order to overcome this obstacle, colleges should introduce BIM to their students so that by the time they graduate college, they can be proficient and apply their skills in the workplace.  I agree with my fellow classmate, Gabriel Carpenter, who predicts what will happen in the workplace soon after the introduction of BIM: “either CAD drafters are expected to learn the new technology, entry-level engineers – who specify that they know the technology – are recruited to draft, or companies have to reach outside the company to hire another firm to do their BIM work for them.” In the end, the industry will be using and expecting everyone to use BIM.

            According to Mr. Eric Kuszewski, a BIM expert who has heavily worked with AutoCAD and Revit, admits that there are some challenges with BIM in the current time.  These include the learning curve and training, level of detailing, interdisciplinary workflow, IT infrastructure, and communication.  He expressed that nowadays BIM has these limitations that might make companies hold out and hesitate on using BIM.  Yet to counteract this argument, Dell and DB+C claimed that “in the United States, architects are the heaviest users of BIM, using it on more than 60% of their projects, compared with 43% of architects who claimed to be BIM users in 2008".  From this, we can deduce that in the next five years twenty percent more, approximately a total of 80%, of architects will be using BIM.  In addition, Jennifer M. McGregor, Executive Director of Obelisk, predicted, “In the next three years, we’ll all be converted to using BIM”.  These optimistic expectations are enough proof that the BIM world is quickly spreading throughout the industries.

Future Outlook on BIM Tools and Parametric Modeling

As presented in my post from last week, I do not believe the progress of BIM and its tools and parametric modeling are not going to be the issue in the building and construction industry.  With time the software and hardware issues will undoubtedly be resolved as well as upgraded and the systems will become more compatible, as well as user friendly.  And, I do not doubt that drafting in BIM will become a specialty skill as mentioned by G. Carpenter and required to a certain degree for those in the industry as mentioned in J. Lancellotti’s post.  The issues that have and will most likely continue to slow down the progress of BIM are the industry conventions that all groups within the industry have built their practices around.  This was addressed by our speaker Eric Kuszewski during our week 3 class.  He addressed the fact that many of the building system drawings and efforts were being doubled as a result of wanting to use BIM to show it one way and then the system engineer or someone else wanting to see in another way, or the “old” way.  He also addressed that this not only affected the engineers and their products, but those dealing with the contracts, deliverables, and metrics.  The groups that work on the latter have built what they do around the existing conventions.

As a result, I believe the BIM execution plan that Kuszewski mentioned will be heavily involved in creating new BIM centered conventions.  I do not believe that in 5 years everything will have completely made the switch to being “BIM-centric,” but the ability for all those involved to work together to shift from the practice of making separate drawings for buildings to virtually creating the building will be much improved as a result of one building era ending as the beginning of another approaches.  These changes may indeed result in the predictions made by M. Tedesco regarding the industry in ten and twenty years.
