First, Layher uploads a client’s 3D digital drawing to a scaffolding application and works to design an affixing scaffold. A preliminary drawing is sent to the client to verify field fidelity and viability. Once the design is greenlit, a local engineer reviews and stamps the drawings.
Next, the same suite of design software outputs 1) a materials lists that accounts for every component, 2) a 2D drawing, and 3) a 3D digital drawing that allows builders to verify each component and connection point in the field.
“The 3D drawings were thorough, clear, and they showed that they looked at doing this other ways,” said Smith.
Smith praises the efficiency and high degree of certainty that results from the process. “By the time you’re done, you know everything from the total weight to how many truckloads [you need]. Advocates for the process cite a reduction in change orders and the elimination of guess work as additional benefits.
Erectors take the printed drawing into the field, and that includes a scan code to the 3D version for quick reference. The 3D plan can be viewed in 360 degrees and magnified or manipulated for detailed view.
“You can spin it turn it, flip it. If you’re up on the scaffold, you can look and see, ‘okay how many clamps do I need?,’” says Smith.
There’s always some degree of differentiation between plans and how things play out in the field, explains Joel Armstrong, lead builder at Sunstate. “These 3D drawings are the best […] you can see the angle, and it saves on time by not doing it the wrong way.”
