A 2010 survey by the Construction Management Association of America found that between 40%-50% of all construction projects were running behind schedule. The number one reason for delays was due to rework. Rework is usually caused by a lack of coordination between contractors and conflicts of systems. It is the cause of 5% of total construction costs and wastes in time and labor costs. The mechanical, electrical, and plumbing (MEP) industries are key players when it comes to a successful construction project. Because they are the most labor intensive trades and directly affect the efficiency of work flow, they must cooperate in order to avoid interference.
Cost and Time Savings
In the last decade, BIM (Building Information Modeling) was developed to increase productivity and avert conflicts. BIM is a modeling design plan that uses 3-D Smart Technology. It allows designers to create electronic drawings of a building’s geometry, spatial relationships, geographic information, and several properties of a building’s components. With BIM, each trade knows when and where it can work and what materials they’ll need without interference with another group. Daily on-site “clash meetings” are a thing of the past because each trade is integrated into the work schedule from day one of the design. In addition to providing a digital representation of a project during its lifecycle, it also provides benefits like wiring diagrams, parts list, exploded views, operations, and maintenance manuals. There are even applications that can check for code compliance. A University of Florida study found that BIM improves 1) quality 2) cost 3) schedule 4) productivity, and 5) safety.
Software like BIM 360 allows a coordinated model to be viewed in its entirety from an I-Pad on-site. It also provides comprehensive cloud based model storage and clash detection. This, along with Go-to-Meeting, lets multiple viewers see a layered portrait of each phase of construction in real time for on-line collaboration sessions.
The days of mountains of paper drawings and frequent trips to the jobsite trailer to view the latest drawings are over. All field supervisors carry smart tablets around the site that allow workers to see updated drawings and photos of completed work for reference. It’s the modeling plan that keeps on giving!
Cutting Edge of Lean Building Efficiency
Tebarco Mechanical invested in its first BIM seat in 2012, ahead of many mechanical companies in Atlanta. Today it has 4 full time BIM specialists. One of the things that makes their team so exceptional is the checks and balances system that exists between the BIM department, the Project
Managers, and Superintendents. All parties attend virtual coordination meetings where they can see real time information and electronic drawings through Bluebeam. Tebarco’s BIM CAVE (Computer Aided Virtual Environment) is second to none with each seat being outfitted with top of the line software and hardware. Sixty inch T.V. monitors are used for collaboration meetings and large scale virtual displays. Tebarco’s experienced BIM team has not only created mechanical plans but also coordinated entire projects.
BIM Software Technologies:
• Trimble Layout – Robotic Layout station that lays out the position of the pipes and equipment with information derived and provided by the BIM model.
• BIM 360 Glue – Software allowing the coordinated model to be viewed in its entirety from an Ipad onsite, and fully comprehensive cloud based model storage and clash detection.
• Boxx Server – Allows us to co-locate and have a BIM seat onsite.
• Got to Meeting – Screen sharing software allowing multiple viewers to view the latest model in real time from any location or device.
• SysQue– Revit Plugin that assists in modeling more accurately and quickly. Comprehensive family libraries, Bill of materials, and spool capabilities.
• A360 Collaboration – Autodesk cloud model storage and more efficient collaboration due to all aspects of the model are stored in one location.
BIM models are now being used to create pre-fabricated materials off site to create even more efficiencies. For more information, contact us at www.tebarco.com
