G-16 Modifies products to site conditions
Products often need on-site changes before final installation, such as cutting access holes for plumbing, electrical and heating and scribing to uneven surfaces, followed by final adjustments so the product works and looks right.
Sub-tasks
- G-16.01 Cuts access holes on site
- G-16.02 Scribes product to fit on site
Modifying products to site conditions
Cutting access holes for utilities on site and scribing products so they fit tightly against untrue walls, ceilings and floors.
Key points
- Access holes (utilities): electrical, heating, plumbing, mechanical.
- The reference point for access holes comes from the drawings and site conditions. Access points are then sealed with paint or edging.
- Testing tools for untrue surfaces: laser level, plumb line, bubble level, water level.
- Scribing tools: compasses, pencils and spacers, contour gauges, scribing wheels.
- Scribing sequence: set in place, mark profile, protect surfaces, cut profile.
- Products are set in place plumb and level against untrue surfaces before the profile is marked.
- Protection: tape, cardboard, polywrap, carpet, limiting personnel access.
Overview
Products often have to be modified on site before final installation. Access holes may need to be cut for plumbing, electrical and heating, and products are often scribed so they fit tightly against uneven surfaces. The cabinetmaker also makes final adjustments so the product works properly and looks good.

What you need to know
- What access holes are for, and the concerns involved in working with utilities.
- Procedures for cutting access holes.
- Why access points are sealed or edged.
Range of variables
- Access holes and utilities include: electrical, heating, plumbing, mechanical.
- Tools and equipment include: jigsaws, circular (track) saw, measuring tapes, levels, drills (hole saws), routers, oscillating multi-tool, paint brushes, rollers.
