Precision Saw Cutting & Core Drilling for Portland Projects

Sawing and coring is the surgical side of commercial concrete work in Portland. New HVAC penetrations, electrical and data conduit runs, plumbing trenches, equipment relocations and demolition of selected elements all require openings cut in slabs and walls without damaging adjacent structure or disrupting the building. Much of this work is done in occupied offices, labs, warehouses and tech facilities.

Silica control is central. Cutting, coring and grinding concrete creates respirable crystalline silica, which Oregon OSHA regulates in construction. Contractors commonly follow the specified exposure control methods, using continuous water feed or shrouded tools with HEPA vacuums, backed by written exposure control plans, training and respiratory protection when required. Indoor work often adds containment, slurry management and noise control.

Equally important is knowing what is inside the concrete. Reinforcing bars, conduits and in some buildings post-tensioning tendons can be hidden in slabs and walls, so scanning or ground-penetrating radar is a standard step before cutting. Structural elements may need the engineer's approval for openings. We aim to cut cleanly, protect the building and leave a safe, documented result, and we recommend confirming engineering and permit requirements before any structural penetration.

Portland-Specific Considerations

Oregon OSHA's silica requirements apply to cutting and coring, so water or vacuum controls, training and exposure control plans are part of every job.
Many Portland-area industrial and tech buildings are occupied or operating, so work often happens after hours with containment and slurry control.
Older industrial buildings may have limited drawings, so scanning and potholing are important before coring.
Water-fed cutting must be managed so slurry does not enter storm drains, particularly near rivers and in the Columbia Corridor, where discharge rules can be strict.
Structural slabs and walls can be part of the seismic load path, so openings may require the engineer's review and, in some cases, permits and special inspection.

Our Precision Saw Cutting & Core Drilling Process

1. Plan and verify the scope
Review drawings, confirm opening sizes and locations, and check whether engineering approval or permits are needed for structural elements.
2. Scan and mark
Use scanning or ground-penetrating radar to locate rebar, conduit and tendons, and mark safe cutting zones.
3. Set up controls
Establish silica controls, containment, slurry collection and safety barriers, and review the exposure control plan with the crew.
4. Cut or core
Perform wall sawing, flat sawing or core drilling with appropriate equipment, supporting and removing cut sections safely.
5. Clean up and document
Remove slurry and debris, inspect openings, and provide records or photos required by the owner or the engineer.

Precision Saw Cutting & Core Drilling FAQ — Portland

Is scanning really necessary before coring a slab?

Yes, it is standard practice. Slabs and walls may contain rebar, conduit, plumbing and sometimes post-tensioning tendons, and hitting them can cause serious safety hazards and costly damage. Scanning with GPR or similar tools helps locate them. For structural elements, the engineer may also need to approve the location of openings.

How is silica dust controlled during concrete cutting?

Common methods include continuous water feed at the blade or bit, or tools with shrouds connected to HEPA-filtered vacuums, plus written exposure control plans and training. Respirators may be required depending on the task and setting. Oregon OSHA enforces these rules, so confirm current requirements and keep documentation on site.

Can sawing and coring be done in an occupied building?

Often yes, with planning. Contractors use containment, slurry management, noise control and scheduled work hours to limit disruption. Some areas, such as labs and cleanrooms, have extra rules. Coordinate with building management and safety staff early so protocols, access and protection of equipment are agreed before cutting begins.
