Structural Steel Detailing

    JPW has a top notch structural steel detailing department located with in our 100,000 Sq Ft facility. JPW uses advance 3D modeling software “Tekla Structures” with and extensive library of steel shapes to produce shop drawings and erection plans. JPW can produce shop drawings for everything we fabricate including joist and deck drawings in half the amount of time compared to conventional detailing programs.

   JPW employees five full-time detailers which use Tekla Structures to develop shop drawings generated from Structural Steel or Architectural drawings produced by the customer. JPW takes this information and inputs it into our modeling software to create a 3 dimensional model drawn to scale. JPW then proceeds to designing connections with the use of “macros” within Tekla. These macro’s let JPW set each configuration specifically for each type of connection design. Whether it be a single shear connection or a double sided bolted clip connection. Using these macros in conjunction with the 3D capabilities it enables JPW to eliminate and accurately manage bolting interferences or potential problems before they become erection problems on-site.  

   Every piece of material whether it be a beam, column, plate, or a piece of angle has a specific drawing created for fabrication. These are what we call shop drawings. Shop drawings at JPW consists of two types: Assembly drawings and Single part drawings. An assembly is a drawing that has all parts that are required to fabricate a column or beam in its entirety so that it will be considered a finished part. This drawing includes an extensive bill of materials on every drawing. A single part drawing is an individual drawing for each clip, plate, channel, etc. to make up an assembly drawing.
Tekla Structures is capable of downloading CNC files for each drawing directly to our CNC machines. This process eliminates each machine operator programming holes and cut lengths. This eliminates mistakes made in programming.

    The last step of the shop drawing process is to create Erection drawings. Erection drawings are drawings that are using to erect the building. These set of drawings consist of Anchor bolt plans, Floor plans, Roof plans, Building elevations, and Details. Erection drawings have all the necessary information required to erect each specific job.(ie. anchor bolt locations, specific beam and column placement, and specific welding or bolting information)
Above and beyond Tekla structures JPW has a full line of software to help every project big or small reach the desired out come required by the customer. JPW’s software include: Bldg. Seismic Design by RAM Advanse, AutoCAD, Pronest, Pedimat, just to name a few.
