Every dimension belongs to an object and a drawing. Original room numbers, object marks, printed values and source regions stay together—even when the answer is unresolved.
464 of 464 photographs have extraction records, containing 27,517 properties. Initial image review is not exhaustive extraction: 0 photographs have passed the full-region check. 66 numbered sheets are reconciled. Modeling and architectural registration are separate work; these counts do not establish a complete building.

Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.
3 count
Printed tube count per radiator under general floor rule; not installed radiator quantity.
Drawing notation: ALL RADIATORS ON THIS FLOOR TO BE 3 TUBE
Printed tube count per radiator under general floor rule; not installed radiator quantity.
20 in
Printed radiator-height default with explicit inch mark and exception retained.
Drawing notation: 20″ HIGH UNLESS OTHERWISE NOTED
Printed radiator-height default with explicit inch mark and exception retained.
Conditional connection route requirement only; no wall penetration locations established.
Drawing notation: ALL RADIATOR CONNECTIONS SHALL BE BROUGHT THRU WALL WHERE POSSIBLE
Conditional connection route requirement only; no wall penetration locations established.
Material assigned only to boots; no sheet-metal thickness inferred.
Drawing notation: ALL GALVANIZED IRON BOOTS FOR COPPER RADIATORS IN HEATING CONTRACT
Material assigned only to boots; no sheet-metal thickness inferred.
Copper applies to radiators named in the boot clause, not automatically every radiator on the floor.
Drawing notation: ALL GALVANIZED IRON BOOTS FOR COPPER RADIATORS IN HEATING CONTRACT
Copper applies to radiators named in the boot clause, not automatically every radiator on the floor.
Printed contract allocation, not installation evidence.
Drawing notation: ALL GALVANIZED IRON BOOTS FOR COPPER RADIATORS IN HEATING CONTRACT
Printed contract allocation, not installation evidence.
Valve requirement for steam drop risers only.
Drawing notation: VALVE ALL STEAM DROP RISERS AT TOP AND BOTTOM
Valve requirement for steam drop risers only.
Locations relative to each applicable riser; no exact heights or valve sizes established.
Drawing notation: VALVE ALL STEAM DROP RISERS AT TOP AND BOTTOM
Locations relative to each applicable riser; no exact heights or valve sizes established.
Numeric value unresolved
Fraction and its unit mark not securely distinguished. Preserve null; no size transfer from other floor or source.
Drawing notation: ALL RETURN RISERS AND RISER DRIPS TO BE [fraction unclear] UNLESS OTHERWISE NOTED
Fraction and its unit mark not securely distinguished. Preserve null; no size transfer from other floor or source.
1 in
Explicit printed one-inch return-runout default; following UNLESS OTHERWISE NOTED qualification applies to sentence. Drip-runout fraction remains separate.
Drawing notation: ALL RETURN RUNOUTS TO BE 1″
Explicit printed one-inch return-runout default; following UNLESS OTHERWISE NOTED qualification applies to sentence. Drip-runout fraction remains separate.
Numeric value unresolved
Drip-runout fractional size and its unit mark unresolved; not supplied by neighboring one-inch return-runout value.
Drawing notation: AND DRIP RUNOUTS TO BE [fraction unclear] UNLESS OTHERWISE NOTED
Drip-runout fractional size and its unit mark unresolved; not supplied by neighboring one-inch return-runout value.
Literal combination-trap designation in legend clause; installed types and quantity not established.
Drawing notation: COMBINATION FLOAT AND THERMOSTATIC TRAPS
Literal combination-trap designation in legend clause; installed types and quantity not established.
Exact legend clause specifies valved bypass. No installed instance count or additional piping topology inferred.
Drawing notation: COMBINATION FLOAT AND THERMOSTATIC TRAPS WITH VALVED BYPASS INDICATED THUS [symbol]
Exact legend clause specifies valved bypass. No installed instance count or additional piping topology inferred.
Caption preserves separate thermostatic-trap convention; no installed quantities established.
Drawing notation: THERMOSTATIC TRAPS INDICATED THUS [symbol]
Caption preserves separate thermostatic-trap convention; no installed quantities established.
