What The Work Involves
More than a list of trades.
Construction is a sequence of decisions, approvals and field work. The descriptions below show how Archéform organizes each major project category.
01
Residential remodeling
Whether the work is limited to one room or extends throughout the home, we organize the sequence before demolition begins. Existing conditions, owner selections, long-lead materials and building-system changes are identified early so the project can move with fewer surprises.
Typical coordination
- Site protection and selective demolition
- Framing and structural coordination
- Electrical, plumbing and HVAC trades
- Cabinetry, tile, flooring and paint
- Inspections, corrections and final walkthrough
02
ADUs and additions
New square footage requires more than construction alone. Zoning, setbacks, structural design, utility capacity, access and the connection to the existing property all affect cost and schedule. We help turn those separate requirements into one buildable plan.
Typical coordination
- Initial feasibility and site review
- Architectural and engineering coordination
- Permit processing and city comments
- Foundation, framing and weatherproofing
- Utility connections and required inspections
03
Commercial tenant improvement
Commercial spaces must support the business while satisfying building, fire, accessibility and landlord requirements. We coordinate the work around occupancy goals, equipment needs, trade responsibilities and required closeout documentation.
Typical coordination
- Existing-condition and plan review
- Landlord and permit coordination
- Partitions, ceilings and finish packages
- Electrical, plumbing, HVAC and low-voltage trades
- Inspections, punch list and turnover
04
Exterior and property improvements
Exterior work succeeds or fails during preparation. We review access, surface condition, localized damage and the correct repair sequence before coatings or finish work are applied.
Typical coordination
- Access, protection and pressure washing
- Stucco, crack and sealant repairs
- Doors, windows, railings and metal surfaces
- Exterior coatings and finish application
- Site cleanup and completion review
