A case study in BIM implementationand advantages

Cuilding Information Modeling (BIM) hasdeveloped from an industry buzz word
into a common process used in a growingnumber of AE projects.The digital model enablesthe owner, contractor,and design team to notonly view a three dimen-sional representation ofthe building, but alsoallows access to non-graphical informationabout the building. Forexample, partition walls
are not just visible in the model, but the typeof gypsum board, steel stud size, and paintcolor are also accessible in the model.
While more time consuming and morecomplicated than 2D drawing, BIM offersmany advantages to the design and construc-tion industry. BIM has proved to facilitatethe construction process and eliminate manyproblems and conflicts before they arise inthe field.
Case study in use of BIM
Structural Design Group used BIM on anew replacement hospital and medical officebuilding in Smyth County, Virginia. The $42million design-build project consisted of a150,000 square foot, 44-bed hospital with
three stories and a lower basement level.The exterior veneer was brick on metal studback-up. The structure consisted of struc-tural steel with composite floor slabs andwas founded on micropiles. Steel momentframes served as the lateral-resisting systemand grade beams were provided between pilecaps. A powerhouse was included withmasonry walls and steel braced frames.
Advantage of clash detection
Each consultant created a 3D model ineither Microstation or Revit. Despite the dif-ferent drawing platforms, the contractor wasable to use Navisworks, an Autodesk soft-ware program, to create one integratedmodel in which the architecture, structure,plumbing, electrical, mechanical, etc. couldall be viewed at the same time. Clashes – orinterference with these systems – weredetected in several locations, including thefollowing:

BCEC and TSPE have made a strategicpartnership with ASCE for the three
groups to host a joint meeting on September13 and 14. How will this benefit memberfirms? Let me count the ways!
1. The annual meetingwill offer a wider range oftechnical sessions. The pro-gram offers four technicaltracks so attendees canincrease their technicalknowledge and learn moreabout programs and ser-vices needed by our clients.Among the topics are the
Mitigation In-Lieu Fee program, EngineeringEthics, and TVA Renewable Energy programsto name just a few. Plus — the technical pro-gram will meet most PDH requirements forthe year at an extremely reasonable price!
2. There will be increased opportunity tonetwork with peers, mentors and potentialclients. With the membership of threestatewide organizations involved, there will bemore opportunity to connect with colleaguesat a time when teaming partners are neededon many of the projects we pursue.
3. There will be opportunity to support thenext generation of students in math, scienceand engineering. The proceeds from The Ten-nessee Engineering Foundation (TEF) lun-cheon on September 13 are directly funneledinto the TEF coffers for MathCounts and forscholarships for college students studying engi-neering. TDEC Commissioner Bob Martineauwill be the featured speaker.
4. Attendance supports the statewide orga-nizations. This event is a source of funding forthe ACEC & TSPE operating budgets — thebudget that supports the organizations’ manyactivities on your behalf throughout the year.
5. It’s an opportunity to directly supportefforts to protect our profession on the legisla-tive front. Through the Tennessee ProfessionalEngineers’ Political Action Committee (TPEPAC), our voice can be heard on the issuesthat are important to our profession andindustry. The PAC Auction on September 13 isalways fun and full of surprises. Participateand spend some dough to raise funds to sup-port PAC activities!
For these reasons, I cannot understand whyyou wouldn’t plan to attend this year’s annualmeeting and join ACEC/TSPE/ASCE as webegin Partnering for the Future. Go towww.acectn.org/Events.htm to sign up today.

BIM advantages (continued from page 1)
• Toilet and sink drain lines passed throughsteel beams in many locations. Either the drainline was relocated or the steel beam was moved
• Underground pipes conflicted with concretegrade beams. The grade beams were either low-ered, the pipes raised, or the pipes adjusted tofit within the middle third of the grade beamdepth to avoid the longitudinal reinforcement.
• A braced frame in the powerhouse wasfound to conflict with a mechanical louver. Thewidth of the tube brace was reduced and theexterior wall was pushed out.
Prior to release of the final construction docu-ments, a fully coordinated model with noclashes was produced, which resulted in fewerRequests for Information (RFIs) during con-struction.
Advantage of coordination Initially, the design team has to decide which
items will be modeled and which will not. Inthe structural model, the main structural steeland foundations are included, but brick hangers,shelf angles, diagonal kickers, and other miscel-laneous steel components are excluded. Theseitems are included in the model prepared by thesteel detailer during the shop drawing process.
The project had a fast track schedule in whichthe structural drawings were issued well beforethe rest of the design team completed theirdrawings. This required the other disciplines tobe involved much earlier in the design. Con-flicts discovered after the steel was in fabrica-tion required the design team to make revisionsthat did not involve changing the structure.
Clash detection and coordination through 3Dmodeling and BIM yielded a successful projectin Smyth County for the design team, contrac-tor, and the owner.
This project is one example of why BIM hasbecome an accepted practice that is transform-ing traditional project deliverable methods andshaping the future of the industry.
