STANDARD FORM 330 (REV. 8/2016) PAGE 25 RESPONSE TO REQUEST FOR QUALIFICATIONS FOR Continuing Professional Consulting Engineering Services-Environmental Engineering #BID 20-07-01 • COVID-19 Cleaning and Disinfection Protocols – the may be generalized or made site-specific. They are used either reactively to clean and disinfect indoor and outdoor areas (high-touch surfaces and transmission sites) in response to known or suspected COVID-19 positive cases, and/or they are used proactively by custodial or cleaning services to perform routine and frequent disinfection sweeps to keep risk of infection down. • COVID-19 Disinfection Oversight and Clearance Inspections and Testing – we have been overseeing several disinfection projects at construction site, office environments, and multifamily residential sites. We perform the final inspections after disinfection and have two different devices to conduct surrogate testing with results directly in the field to further evaluate the efficacy of the cleaning process. • Training – we can provide training to internal custodial staff on performing routine disinfection and the use of best practices and personal protection equipment. Forensic Investigations- With the onset of energy conservation in the early 1970’s came the realization that measures taken to reduce the operating costs of buildings often resulted in the manifestation of a range of occupant-related health complaints. Typically, these complaints are general and range in their description from watery eyes, sinus infections, headaches to severe allergic triggers and asthma. The diagnosis of buildings and correlation of findings within a building to these health complaints is difficult. Often simple testing does not provide the required information and the Client is faced with paying for services that do not meet their goal of improving the indoor air quality and thereby reducing occupant complaints. GBTS recognizes this latent fault and has designed a project approach to solve indoor air quality -related issues while avoiding costly and misleading laboratory testing, where possible. A typical GBTS IAQ assessment includes the following:  Interview with building occupants and historical review of complaints.  Inspection and characterization of the building and HVAC system.  Visual inspection of the facility for evidence of microbiological amplification or water damage.  Measurement of thermal comfort parameters (temperature, relative humidity).  Direct reading for carbon monoxide  Determination of the amount and distribution of fresh air.  Evaluation and documentation of operations, which may impact, air quality.  Determination of pressure differentials and mapping of air flow patterns.  Identification of moisture content in building materials. In some situations the collection of laboratory samples are necessary to meet the specific project goals of the Client. Samples are often collected in response to pending litigation or to demonstrate that previous actions initiated by the Client have been effective in improving indoor air quality. When collecting samples, GBTS is careful to explain the parameters to the Client and to develop a carefully executed sampling plan to ensure that data collected can be properly interpreted. Examples of samples collected by GBTS include:  Airborne mold spores and bacteria.  Airborne particulate characterization.  Surface mold spores  Dust mites.  Total Volatile Organic Compounds (TVOCs).  Dust Characterization.  Allergens such as cat, dog, and cockroach.  Carbon monoxide.  Radon gas.
