As a virtual representation of the actual facility, the 3D model incorporates mechanical systems plus architectural, civil and structural elements, and more. Considered a shared resource by all the main trades on a project, the model is where coordination occurs to achieve a building’s coordinated layout and design.\u003c/p>\u003cp >Starting their work shortly after groundbreaking in early spring 2021, the Olson and Uponor BIM teams finished modeling the first of the building’s two levels around Oct. 1, 2021. \u003c/p>\u003cp >“Populating the digital model is just the start,” said Tim Kiepe, business development manager for Uponor BIM Services. “After the model has been converted to fabrication content, we move into the coordination phase. This phase is a delicate dance between all the trades vying for their respective spaces on the job while also adhering to all owner requirements.”\u003c/p>\u003cp >Here is where potential clashes and collisions — one contractor’s ductwork running into another’s drain, waste, and vent (DWV) stack or conduit — are discovered and resolved before becoming actual job site problems. \u003c/p>\u003cp >“It is also where the original system layout can be altered to gain welcome efficiencies wherever we can create them in a way that is acceptable to the specifying engineer,” added Marsh. \u003c/p>\u003cp >At Centennial, one such change was a request to Uponor BIM Services to raise an underground plumbing drainage line several feet. Doing so would spare Olson from having to dig a deeper trench, saving labor as well as earth-moving equipment rental costs. A second efficiency gained was to eliminate several offsets in the piping layout. Straighter pipe runs result in fewer pipe connections, which is another time- and money-saver. \u003c/p>\u003cp >“When you are 3D modeling pipe runs, you can recognize that sort of problem and then optimize the pipe’s path,” said Marsh. “Not having to dig an extra 3-4 feet saves us a ton of work in the field.”\u003c/p>\u003cp >Once these clash-detection issues have been resolved, the next step is to generate various types of drawings to guide the fabrication and installation work to come:\u003c/p>\u003cul >\u003cli >Install drawings for the relevant trades to approve, including mapping documents for field installation support, along with bills of material for ordering product: At Centennial, drainage pipe running through grade beams must be sleeved. As the beams were being built, Uponor BIM Services generated digital drawings, showing the positioning of the oversized pipe sleeve with the drainage pipe inserted through it.\u003c/li>\u003cli >Two-dimensional spool drawings for prefabricating pipe assemblies for eventual installation on the job site: Uponor BIM Services provides Olson electronic files containing the exact specifications of the various pipe assemblies, from the precise lengths down to end-beveling and grooves for no-hub, band-style fittings. The data is given to Olson’s fabrication-shop personnel, and the pipe is cut and fabricated to exact measurements, with the fittings installed according to the drawings. The cutting is optimized in a way that minimizes material waste, getting the maximum use of the pipe lengths. \u003c/li>\u003cli >Hanger and support layouts, fully compliant with relevant piping codes as well as project specifications: The coordination service also includes exporting hanger points for use with a total station, an electronic/optical instrument that helps determine exactly where the imbeds, or “bang-its,” need to be located for code-compliant spacing.
