Facade Restoration Assessment & Specification Framework
Assess historic facades and generate ICOMOS-compliant restoration specifications
What You Can Do
You can conduct comprehensive facade condition assessments across historic masonry, stone, terra cotta, cast iron, and wood materials. The framework guides you through visual analysis, material characterization, deterioration documentation, and phased intervention planning—then generates detailed restoration specifications that meet ICOMOS and NPS Preservation Brief standards. This ensures your restoration decisions are evidence-based, reversible where appropriate, and properly documented for contractors, stakeholders, and future reference.
Features
Systematically document existing conditions using standardized categories (material type, deterioration patterns, extent mapping, structural implications)
Identify original materials, historic techniques, and mortar/finish compositions to ensure in-kind matching rather than incompatible repairs
Classify failure mechanisms (water infiltration, salt crystallization, biological growth, mechanical damage) to address root causes, not just symptoms
Develop phased strategies that balance urgent stabilization, reversibility principles, and budget constraints across building sections
Generate technical specifications compliant with conservation standards, including material sourcing criteria, application methods, and reversibility language
Create assessment reports and specification packages suitable for grant applications, contractor bidding, insurance claims, and regulatory approval
Evaluate replacement vs. repair vs. stabilization-only approaches with preservation impact and cost-benefit frameworks
Example Output
Facade Assessment Report (Brick & Terra Cotta)
- South elevation: Common bond masonry with cast stone band courses (1910-1920 era)
- Deterioration: Spalling brick (8% of surface), failed mortar joints (Class III), cast stone surface crazing
- Root causes: Water penetration via open mortar joints + interior moisture migration
- Phase 1 (Year 1): Repoint mortar using NHL 3.5 lime, match brick with salvaged stock
- Phase 2 (Year 2): Cast stone consolidation using compatible epoxy injection
- Cost: $240/sq ft (market rate with material matching)
Technical Specification Sample Mortar Repointing: 1:2.5 lime:sand, NHL 3.5 binder, aggregate sourced from original geological region, joint depth 2.5x width, struck flush profile matching existing, applied with traditional hand tools (no power grinders).
