Engage a certified grader to assign visual or machine grades, confirm species, and measure defects, then let the engineer translate that into allowable stresses. Where data are thin, deploy stress‑wave timers, resistographs, or core sampling. Calibrate design values with safety margins, documenting assumptions, photos, and calculations within the structural narrative.
Test reclaimed brick lots for absorption, saturation coefficients, and compressive strength, then limit exposure conditions appropriately. For steel, cut coupons for mechanical properties and chemistry, verify weldability, and inspect for hidden corrosion. Coordinate anchors, coatings, and galvanic isolation so patina remains beautiful while assemblies meet strength, durability, and service expectations.
Pair reclaimed surfaces with tested assemblies or engineering judgments referencing UL design numbers where available. Ensure cavity fire blocking, intumescent coatings as needed, and compatible membranes. Validate rainscreen ventilation, drainage, and vapor control through hygrothermal modeling, then commission field tests so the realized build proves weathertight and safe under real operating conditions.
