Job Site Monitoring

Job-site Monitoring & Phsycrometry 

Allstar Restoration has implemented project monitoring & phsycrometry readings an all of our water loss claims. Phsycrometry & project monitoring provide a daily log of humidity & temperature readings in the affected , unaffected & outside areas. This allows us to determine when a structure is dry reducing the cost over runs of equipment left running on site.


  • Name of insured claim number 
  • Dates & times of service
  • Detailed daily logs
  • Technician performing the service instrumentation used  category & glass of water 
  • DB= dry bulb temperature of the affected, unaffected and exterior areas
  • RH = relative humidity of the affected, unaffected & exterior areas.
  • Specific humidity  (amount of water vapor in a sample of air) in the affected, “GPP” unaffected & exterior    areas.
  • Drying goal for the affected area.
  • Accurate room dimensions & measurements.
  • Scope of work & restoration plan.

As the drying process continues, the amount of air flow necessary gradually decreases. With the removal of bound water the necessity for air movers decreases. The IICRC S 500 standard & Reference Guide for Professional Water Damage Restoration defines a DRY STANDARD as “a reasonable approximation of conditions prior to the moisture intrusion, or by comparing moisture content conditions of the some type of building materials in the unaffected areas of the building.

Project Monitoring & Psychometric Readings will ensure that proper charges are being invoiced for equipment usage & equipment sizing as recommended by the IICRC S 500 standard & Reference Guide for Professional water Damage Restoration.

 Category of  Water

The categories  of water,  as defined  by this document,  refer to the  range of contamination   in water,  considering both its originating  source and its quality after it contacts  materials  present on the job site.  Time and temperature   can also  affect  the  quality  of water,  thereby  changing  its category.    Restorers  should  consider potential contamination, defined as the presence of undesired substances; the identity, location and quantity of which are  not  reflective  of  a  normal  indoor  environment;   and  may  produce  adverse  health  effects,  cause  damage  to structure and contents and/or adversely affect the operation or function of building systems.

Category   1

Category  1 water originates from a sanitary water source and does not pose substantial  risk from dermal, ingestion, or inhalation exposure.   Examples of Category  1 water sources can include, but are not limited to: broken water supply lines; tub or sink overflows with no contaminants;  appliance  malfunctions  involving water-supply lines; melting ice or snow; falling  rainwater; broken toilet tanks, and toilet bowls that do not contain contaminants  or additives.   However, once clean water leaves the exit point, it might not remain clean once it contacts other surfaces or materials.

The cleanliness  of Category  1 water  may deteriorate  to Category 2 or 3 for many reasons,  including  but not limited to: contact with  building  materials,  systems  and contents;  mixing with soils and other contaminants,    Some factors that  influence  the  potential  organic  and inorganic  load  in a structure  include  the age and  history  of the  structure, previous   water  losses,  general   housekeeping,    and  the  type  of use  of the  structure.   (e.g.  nursing   home,  hospital.   day care, warehouse,  veterinary  clinic) and, elapsed time or elevated  temperature.  Odors can indicate that Category  1 water  has deteriorated.

Category   2 

Category  2 water  contains  significant  contamination   and  has the  potential  to  cause  discomfort  or sickness   if contacted   or  consumed   by  humans.     Category   2  water   can  contain   potentially   unsafe   levels  of microorganisms  or nutrients for microorganisms,  as well as other organic or inorganic matter (chemical or biological). Examples  of category 2 water can include, but are not limited to: discharge from dishwashers  or washing  machines; overflows  from washing  machines;  overflows from toilet bowls on the room side of the trap with some  urine but no feces; seepage due to hydrostatic  pressure; broken aquariums  and punctured water beds.

The  cleanliness  of  Category  2 water  can  deteriorate  for  many  reasons,  including  but  not  limited  to:  contact  with building  materials,  systems,  and contents;  mixing with soils and other contaminants.  Some factors that  influence the potential organic and inorganic load in a structure include the age and history of the structure, previous water  losses, general housekeeping,  and the type of use of the structure and, elapsed time or elevated temperature.

Category   3

Category  3 water  is grossly  contaminated  and can  contain  pathogenic,  toxigenic  or  other  harmful agents.   Examples  of Category  3 water  can  include.  but are  not limited to:  sewage:  toilet  backflows  that  originate from beyond the toilet trap regardless  of visible content or color; all forms of flooding from seawater;  ground surface water  and  rising  water  from  rivers  or  streams,  and  other  contaminated   water  entering  or  affecting  the  indoor environment,  such as wind-driven  rain from hurricanes, tropical storms, or other weather-related  events.   Such water sources may carry silt, organic matter, pesticides, heavy metals, regulated materials, or toxic organic substances.

CIass of water

The term  ':class of water"  is the  initial  determination  of the  amount  of water  and  the  likely  or anticipated   rate  of evaporation   based  upon .the  quantity   and  type  of  wets   materials   in  the  affected   space. Determining  the classes  of water  IS an essential  part of, calculating  the  amount  of  initial dehumidification   capacity necessary  to handle the potential ~mount of water that will evaporate within the affected area, and air movement for the drying process. Classes provide a point of reference to aid in the type, size and amount of equipment initially. Installed on a water damage restoration project however situation can arise that require adjustments to the type and size of equipment  being used during the drying process.  This information  should be gathered during the moisture Inspection of the affected. The classes are divided into four separate descriptions.

  • Class  I (least amount  of water, absorption  and evaporation):  Water losses that affect only partof a room or area, or larger areas containing  materials  that have absorbed  minimal moisture.  Little or no wet carpet and/or cushion  is present.
  • Class 2 (large amount  of water, absorption  and evaporation):  Water losses that affect at
  • least an entire .room of carpet and cushion  (pad). Water has wicked  up walls less than 24 mches.  There IS moisture  remaining  in structural  materials  (e.g., plywood,  particle  board, structural  wood, VCT, concrete.  substructure  soil).
  • Class 3 (greatest  amount     of water,  absorption  and evaporation).  Water may have come from  overhead.  Ceilings,  walls, Insulation,  carpet, cushion  and subfloor  in virtually  the entire area are saturated.
  • Class 4 (Specialty  drying situations):  These consist of wet materials  with very low permeance/porosity(e.g., hardwood,  plaster,  brick, concrete,  light weight  concrete  and stone). These types of losses may require  longer drying times and special  methods.
