Cut to Your Spec
“Sink by owner” is not cutout information.
The shop needs the exact item, current template, mounting method, location, and approval. The same rule applies to faucets, dispensers, grommets, cooktops, pass-throughs, plumbing, and every other opening.
Build a cutout schedule
Use one row per penetration:
| Field | Required information |
|---|---|
| Top mark and room | Same IDs used on shop drawings and labels |
| Item | Sink, faucet, grommet, dispenser, equipment, pipe, or other |
| Manufacturer/model | Exact approved product |
| Template source/revision | Current manufacturer file or verified physical item |
| Mounting | Drop-in, undermount, integral, flush, or project-specific |
| Size | From the approved template—not catalog nominal size |
| Location | Two fixed references or approved centerlines |
| Orientation | Rotation, handedness, front/back |
| Edge/reveal | Material-specific finished condition |
| Status | Submitted, approved, on hand, or held |
Attach the source file. Do not paste a product-page screenshot without the current template.
Coordinate what sits around the hole
Check the cabinet opening, sink bowl, clips, faucet body, drain, disposal, supply lines, backsplash, mirror, outlets, brackets, and drawers. A cutout can be dimensionally correct and still block mounting hardware or cabinet access.
ANSI/AWI 1236 structural requirements address cutouts and the surrounding countertop condition (AWI structural requirements). Material manufacturers also publish product-specific fabrication instructions; Corian’s documentation library is one example (Corian documentation library).
Protect corners and narrow webs
Inside corners and narrow material between a cutout, seam, front edge, or backsplash can concentrate stress. Follow the selected system’s minimums, corner-radius, reinforcement, support, and seam restrictions. Do not invent a universal clearance number.
If the design cannot meet the product requirements, issue an RFI with a marked option: move the opening, change the sink, change the top geometry, add support, or select another assembly.
Accessible sinks require a full section
An accessible sink top is not resolved by lowering the surface. Review clear floor space, knee/toe clearance, sink-bowl depth, piping, protection, faucet reach, and counter height as one section. The U.S. Access Board publishes the governing federal accessibility standards and figures (ADA Standards). The project’s design professional determines the applicable condition.
Release rule
The shop-drawing review checklist should show each cutout as approved or held. If one sink is late, release unaffected top marks only when the package clearly separates them.
Precision Edge needs exact cutout information with the commercial countertop drawings. Send the model and template before production—not after the sheet is on the machine.
