Project scopes — Residential vs commercial
Same saws, different jobs: residential and commercial scope, side by side
The cutting physics does not change between a Littleton cape and a 495-corridor warehouse. Everything around the cut does: who designs it, who approves it, what paperwork rides along, and what “done” has to include. This page scopes both, so each side can borrow the other's discipline where it helps.
The two scope sheets
The typical scopes
- Egress window/door openings in foundation walls for finished basements
- Trench cuts for bathroom additions, drain replacement, and radon rough-ins
- Cores for plumbing, mini-splits, generators, EV and panel upgrades, septic (Title 5) connections
- Driveway and walk cuts for widenings, aprons, and drainage
- Removal of failed patios, walks, and pads (breakout + haul)
What the homeowner owns
- Layout: where the hole/opening goes — marked and approved before cutting
- Permits: building permit for structural openings and egress (Littleton building department); the cutting itself rides under the project's permit
- Dig Safe: 811 notice for any digging — trenching and exterior work — at least 72 hours ahead, weekends/holidays excluded
- Decisions: patch-back, lintel/header, and finish work belong to the owner's builder scope unless expressly included
The typical scopes
- Tenant fit-out openings: doors, louvers, ducts, storefronts in tilt-up and precast
- MEP penetrations at scale — coring programs of dozens to hundreds of holes on a scan-verified layout
- Slab trenching and panel removal for process, lab, and warehouse rework
- Structural modifications with engineered details: beam pockets, partial demolitions, wire-sawn removals
- Off-hours and phased cutting in occupied facilities, schools, and healthcare-adjacent space
What the project owns
- Submittals: silica exposure control plan, insurance certificates, equipment and method statements before mobilization
- Scanning: GPR verification of layouts on above-grade or PT slabs as a contract requirement, with reports filed
- Coordination: structural engineer's details for openings in load-bearing elements; shoring where specified
- Closeout: slurry and waste documentation, patch/leave conditions per spec section, punch-list walk
The overlap worth stealing. Homeowners should borrow the commercial habit of a written scope — one page listing cuts, sizes, removal, patch-back, and disposal beats a verbal “while you're here.” GCs should borrow the residential habit of deciding layout with the person who lives with the result in the room. Both sides: the scan question and the slurry question get asked before the saw starts, on every job, at every scale.
Engineer sign-off: where the line sits
Cutting a non-structural slab-on-grade for a drain: normally no engineer needed. Cutting an opening in a foundation wall under a bearing point, an above-grade structural slab, a beam, or anything post-tensioned: engineer's design and direction first. Enlarging an existing opening “just a few inches” in a structural wall is still structural. When in doubt, the rule is cheap: ask the building official or an engineer before the cut, not the insurance carrier after it.
