1.4 DEFINITIONS
A. Actual Growth: molds that have colonized a substrate, formed fungal mycelia, growth structures and spores; are active or dormant; visible or hidden.
B. Air Filtration Device (AFD): depending on the mode of use, an AFD that filters (usually a HEPA) and recirculates air is referred to as an air scrubber. One that filters air and creates negative pressure is referred to as a negative air machine.
C. Airlock: a system for permitting ingress or egress without permitting air movement from a contaminated area to an uncontaminated area.
D. Assessment: a process performed by an indoor environmental professional that includes the evaluation of data obtained from a building history and inspection to formulate an initial hypothesis about the origin, identity, location and extent of amplification of mold contamination. If necessary, a sampling plan is developed, and samples are collected and sent to a qualified laboratory for analysis. The subsequent data is interpreted by the indoor environmental professional who may then develop a remediation plan.
E. Authorized Visitor: The Owner's representative, the Consultant, or a representative of a regulatory or other agency having jurisdiction over the project who has entered their name into the Contractor's Daily Log.
F. Condition 1 (normal fungal ecology): an indoor environment that may have settled spores, fungal fragments or traces of actual growth whose identity, location and quantity are reflective of a normal fungal ecology for a similar indoor environment.
G. Condition 2 (settled spores): an indoor environment which is primarily contaminated with settled spores that were dispersed directly or indirectly from a Condition 3 area, and which may have traces of actual growth.
H. Condition 3 (actual growth): an indoor environment contaminated with the presence of actual growth and associated spores. Actual growth includes growth that is active or dormant, visible or hidden.
I. Containment: a precaution used to minimize cross-contamination from affected to unaffected areas by traffic, material handling or airborne distribution. Containment normally constitutes of 6-mil polyethylene sheeting, often in combination with negative air pressure, to prevent cross-contamination.
J. Contaminated: the presence of indoor mold growth and/or mold spores, whose identity, location and quantity are not reflective of a normal fungal ecology for similar indoor environments, and which may produce adverse health effects, cause damage to materials and/or adversely affect the operation or function of building systems.
K. Critical Barrier: one or more layers of plastic sealed over all openings into a work area or any other similarly placed physical barrier sufficient to prevent mold spores from migrating to an adjacent area.
L. Cross-Contamination: the spread of contaminants from an affected area to an unaffected area.
M. Curtained Doorway: a constructed device to allow ingress or egress from one room to another while permitting minimal air movement between the rooms.
N. Engineering Controls: the utilization of methods, equipment or containment in such a manner that they limit the exposure of remediation workers and occupants to contaminants and prevent the introduction of contaminants to surrounding uncontaminated areas and contents.
O. Fungi: one of the five kingdoms into which living things are categorized. Fungi have distinct nuclei and include a variety of types, such as molds, mildews, yeast and mushrooms. Fungi range in size generally from 2 to 20 microns and are ubiquitous in soils, water and air.
P. High Efficiency Particulate Air (HEPA) Filter: Means a type of filtering system capable of filtering out particles of 0.3 microns or greater diameter from a body of air at 99.97% efficiency or greater.
Q. HVAC: an acronym for “heating, ventilation and air-conditioning”
R. Negative Air Machine: see Air Filtration Device
S. Personal Protective Equipment (PPE): safety items designed to prevent exposure to potential hazards. Examples include: respirators, gloves, goggles, protective clothing and boots.
T. Post-remediation verification: an inspection and assessment performed by an indoor environmental professional after a remediation project, which may include visual, olfactory and/or sampling methodologies to verify that the building, system or contents have been returned to a Condition 1 status.

1.7 REMEDIATION CONTRACTOR QUALIFICATIONS
A. Training. The Contractor’s supervisor of the work crew must attend a recognized training program by the Indoor Air Quality Association (IAQA), the Institute of Inspection Cleaning and Restoration Certification (IICRC), or similar non-profit organization. Proficiency should be demonstrated by an industry certification such as one from the American Indoor Air Quality Council (AmIAQC).

C. Demonstrated Ability of Workers. The Remediation Contractor must demonstrate that it has (or will have) a sufficient number of remediation workers who have successfully completed in-house training regarding mold.
D. Insurance. The Remediation Contractor must demonstrate that it has sufficient coverage to meet owner’s requirement. E. The Contractor shall secure, pay for, and maintain in full force and effect until no longer necessary, all necessary licenses, permits, and permissions required by federal and state law, city ordinance, statute, or regulations.
E. The Contractor acknowledges that he has acquainted himself with all conditions that may affect the work as would be evident from a thorough investigation of the job site and these specifications covering the work.
F. It shall be the responsibility of all Contractors and Subcontractors to carefullly examine all specifications pertaining to all phases of the construction in order that the Contractor and Subcontractors may foresee all requirements for coordination of their work. Claims based on unforeseen requirements will not be considered.
G. Should any error or inconsistency appear in the Specifications, the Contractor, before proceeding with the work, must make mention of the same to the project coordinator for proper adjustment, and in no case proceed with work in uncertainty.
