Standing Water Volume - Gallons, ft^3, and weight from affected area and depth.
Negative Air Machine Sizing - Required CFM and unit count from room volume and target ACH.
HEPA Scrubber Filter Life - Estimated filter days from CFM, runtime, and particulate category.
Thermal Imager Delta-T Reference - Typical surface-temperature differentials for moisture, insulation, and electrical hotspots.
Containment Air Balance - Required net negative CFM via Q = 2610 * A * sqrt(delta_P) and recommended NAM count.
Drying Chamber Air Turnover - Actual ACH from air-mover and dehu CFM and gap to target ACH.
Drying Log (IICRC S500 Boundary Test) - Multi-row drying log: ambient / chamber paired daily readings.
Equipment Power Draw vs Circuit Capacity - Total amps drawn by drying equipment, and how many 15/20/30 A circuits it needs.
Drying-Chamber Fresh-Air / CO2 Buildup - Required fresh-air exchange (cfm) and air changes per hour to hold a target CO2.
Moisture Removed by Grain Depression - Water a dehumidifier removes per hour and over the run, from its grain depression and airflow.
Evaporation Load / Dehu Demand - Estimated initial water load (gal and lb), first-24-hour removal target.
Asbestos / Lead Abatement Containment Take-Off - Containment poly sheeting, the negative-air machine count for the required air changes.

Wicking-Height Flood Cut and Demolition Takeoff - Turns a wall run and flood-cut height into the demolition takeoff a tech marks on the wall.
Trapped Ceiling-Cavity Water Load and Collapse Screen - The distributed load (a foot of water is 62.4 psf), total weight.
Field-Effective Dehumidifier Capacity at Chamber Grain Depression - Derates a nameplate AHAM pint rating to its field output as the chamber dries and the inlet grains fall.
S500 Class-of-Loss Screen by Wetted-Surface Fraction - Turns a wetted-surface field read into a candidate IICRC S500 Class of water intrusion.
Desiccant Process-Airflow Sizing for Deep and Low-Temperature Drying - Process airflow a desiccant dehumidifier needs to carry a target water-removal rate.
Drying-System Balance (Installed Dehu vs Evaporation Load) - Checks whether the installed dehumidification keeps up with the estimated evaporation load.
Bound Water in Wet Materials - Estimates the weight (lb) and volume (gal) of water held in affected materials that drying must evaporate.
Disinfectant / Antimicrobial Contact (Dwell) Time Reference - Label-typical wet contact (dwell) time for common EPA-registered antimicrobial classes.
Carpet / Cushion Restore-vs-Replace Decision (IICRC S500) - Maps water category, the affected component (carpet vs cushion).
Water Category Deterioration Over Time (IICRC S500) - Applies the S500 principle that water category is determined at the time of remediation, not by the source alone.

Injection / Wall-Cavity Drying System Sizing - Sizes an injection / wall-cavity drying system.
Drying Completion Projection (Days to Goal) - Projects how many days a material needs to reach its dry goal from the moisture-content drop observed between readings.
Drying-Equipment Sensible Heat Load and Ventilation - The sensible heat drying equipment dumps into a chamber, and the ventilation to clear it.
Fire-Exposed Wood Char Depth and Residual Capacity - Screens whether a charred wood beam or post kept enough sound section to carry load after a fire.
Dry-Sponge Soot Cleaning Takeoff and Seal Coat - Turns soot-affected wall and ceiling area into the chemical sponges, labor hours.
Ozone Deodorization Sizing, Time, and Lockout - Sizes an ozone shock deodorization by treatable volume, with the safety lockout up front.
Smoke Residue Type and Cleaning Method Screen - Maps an observed smoke residue (dry, wet, protein, fuel-oil/puffback, or synthetic) to its cleaning method.
Thermal/ULV Fog Deodorizer Dosage - Sizes the deodorant a thermal or ULV fogging pass consumes.
