Office pricing can change with demolition, hazardous-material responsibilities, protection, partitions, doors and hardware, ceilings, flooring, paint, lighting, power and data, plumbing, HVAC, fire-alarm or sprinkler coordination, reception millwork, furniture interfaces, signage, permits, inspections, access, after-hours work, cleanup, and concealed conditions.
The written quote should name confirmed work, exclusions, allowances, owner-supplied items, design and permit responsibilities, building charges, assumptions, milestones, payment terms, and change rules. If a site condition or approval is unknown, record the next check rather than hiding it inside a broad allowance.
