1. Contaminated Site Remediation
After a homeowner noted that their fuel oil needed to be refilled more quickly than normal, they discovered that there was a leak associated with the above ground storage tank. KCI was retained to conduct an investigation to satisfy the TSSA requirements to assess whether the underlying soil and groundwater regimes had been adversely impacted with petroleum hydrocarbons (PHCs). Based on field observations and analytical laboratory results, it was concluded that a subsurface investigation and remediation was considered warranted. KCI drilled boreholes and installed groundwater monitoring wells to delineate the subsurface soil and groundwater impacts. Due to the nature of the site and the presence of contaminated soil underneath the residence, the structure had to be demolished and significant excavation had to be completed to depths exceeding 10.5m. Over the course of the next year, KCI monitored and guided the remedial efforts until the extents of the PHC impacts had been remediated.
2. Mould Assessment
A two-storey residence sustained extensive water damage and associated mould as a result of an ongoing hot water tank leak that went unnoticed for an extended period of time. As a result, extensive mould growth was present throughout the basement and main floor. KCI provided consulting services to determine the extents of mould growth/water impacts with the use of field data and analytical results. A detailed scope of work for mould abatement was provided to the client, and once completed, KCI returned to the site to complete a final assessment to confirm mould growth was removed, building materials were dry, and airborne/surface mould spore concentrations were acceptable according to industry standards.
3. Forensic Investigation
4. Designated Substance Survey
When a fire destroyed a multi-unit residential building, KCI was retained to complete a Designated Substance Survey to identify any hazardous materials including asbestos that may be present in the building. The analytical laboratory identified Asbestos in the wall plaster in the building. Due to the close proximity to multiple commercial and residential buildings, KCI liaised with the Ministry of Labour to conduct and coordinate the demolition efforts. Additionally, air sampling for any airborne asbestos fibers was set along the perimeter to ensure that high concentrations of fibers did not migrate off site.
5. Soot and Chemical Migration Assessment
At a former multi-building government complex that was repurposed into a mix of commercial, industrial, and residential units, a chemical fire broke out and consequently damaged the complex. In order to determine the extents of the fire related particulate damages, KCI was brought in to complete soot testing, to comment on any potential chemical transport, and to complete a Designated Substance Survey. Over the course of three days, KCI staff collected airborne and surface samples of fire-related particulate to determine if fire‐related particulate was present, and if the fire‐related particulate present was associated with the source material provided. Based on the analytical results, fire-related particulate had migrated throughout the building. As such, KCI was able to provide cleaning recommendations to ensure a safe remediation. In addition, due to the nature of the fire, KCI staff also completed air sampling throughout the building, targeting specific chemicals that were impacted during the fire. Fortunately, all submitted samples were below occupational limits.
6. Drinking Well Water Sampling
7. Phase I/II Environmental Site Assessment
8. Indoor Air Quality Assessment
9. Large Scale Mould Assessment
When the air drier associated with an ice rink in a sports complex malfunctioned, staff noted dark colourations of suspect mould growth on building materials associated with the ice rink. KCI was brought in to complete a mould assessment in the sports complex. Elevated mould spores and elevated relative humidity levels were identified in numerous areas throughout the complex. The extensive and complex nature of the project site required a significant amount of project management on the part of KCI to work with all involved parties including government officials to ensure that the project proceeded smoothly and safely. Portions of the complex remained open to the public during the mould abatement. As such, KCI completed weekly airborne mould spore sampling to ensure public safety. Once the abatement was complete, KCI staff returned to the subject site to complete post abatement assessment to confirm that that all mould-impacted building materials had been removed, building materials were dry, and that air and surface mould spore concentrations were acceptable according to industry standards.
10. Marijuana Grow Operation
A fire occurred in a multi-use commercial/residential building. The fire was associated with a burst light bulb in a legal marijuana grow operation within the building. KCI was retained to determine areas of moisture accumulation, asbestos sampling of affected areas, and also determine extents of smoke migration. This was done using forensic investigative techniques, coupled with field data and analytical laboratory results. This information aided the appraiser is devising a targeted scope of work for demolition and repairs. KCI also discovered and differentiated areas of historical water ingress and associated pre-existing mould growth which were separate from the fire-related damages. These areas were then excluded from the appraisers’ scope of demolition/repairs.
