Exclusions: structural or concealed-damage repairs, hazardous-material testing/remediation, layout or service relocation, panel/duct upgrades, custom glass, niche/bench, specialty tile patterns and work outside this room. If a concealed condition appears, document it and agree scope, price and schedule before affected extra work.
Internal risk reserve: $535 ($300 for extra preparation labor and $235 for incidental access/disposal costs). It is an internal budgeting allowance, not an automatically refundable client selection allowance. Replace with a project-specific risk assessment.
