Scentroid's Approach for
Monitoring Air Quality in Pre-Construction, Construction Site and Construction Project
During the Pre-Construction Phase, some property requires a Baseline Property Condition Assessment (BPCA) to identify any potential problems with the property, including hazards, chemicals, or odour issues. The assessment will affect the purpose and value of the property.
Once the property is developed into a Construction Site, it could potentially serve as a source of localized pollution which impacts workers and surrounding communities. These sites can be hot-spots for diesel emissions, noise pollution, volatile organic compounds, and particulate matter hazards.
As for Construction Project, indoor air quality could also serve as an important health and safety concern. Common issues associated with indoor air quality include: poorly maintained HVAC systems and contamination by construction materials, glues, fiberglass, particle boards, paints, and even dangerous airborne chemicals.
From Pre-Construction, Construction Site to Construction Project, we provide a comprehensive approach to air quality monitoring for different needs of construction work.
Pre-Construction Phase
Our SM100i Olfactometers can provide you a non-biased instant result of odour activity. Additionally, we also recommended using our portable analyzer TR8+ Pollutracker and US20 Urban Scanner with integrated noise sensors for chemical and noise analysis on-site.
An odour assessment will determine the purpose of the land and design the use of space accordingly, especially for residential development. Noise analysis will help justify the noise complaints made during construction.
Let us help you with Pre-Development, Construction Site and Construction Project Air Monitoring!
Construction Site
Our monitors contain a database that lists, by source, the amount of air pollutants discharged into the atmosphere during a specific period which will assist you to complete an emission inventory.
The following are the two main tests for emission inventory:
Sludge Process Testing
Sludge concentration, age, the dissolved oxygen concentration, the proper distribution of flow to parallel treatment units, and management of sludge
Fugitive Emission Measurement
Emissions of gases or vapors from pressurized equipment due to leaks and other unintended or irregular releases of gases, mostly from industrial activities
* Integrated Noise Sensor on your air monitor is recommended
Pollutants from Construction Site
The following is a list of recommended monitoring options for your site:
- Particulate Matter (PM1, 2.5, 10)
- Nitrogen Oxide (NO)
- Carbon Monoxide (CO)
- Carbon Dioxide (CO2)
- Sulphur Dioxide (SO2)
- Ozone (O3)
- Nitrous Oxide (N2O)
- Formaldehyde (CH2O)
- Volatile Organic Compounds (VOC)
- Ethanol (C2H6O)
- Butane (C4H10)
- Nitrogen Dioxide (NO2)
- Methane (CH4)
- Odour
- Noise Pollution
- Plus more
Construction Project
A few common pollutants from renovation are dust, Volatile Organic Compounds, Formaldehyde, and Asbestos. Some of the pollutants are critical for long-term health issues. Customized your AQmini with noise sensor and replaceable battery so you’ll able to hand on a safe and renovated home to your client.
Monitoring Overview
Track your sensitive receptors, and view the direct effects an emission source may have on them, down to the odour unit per second value!
Using “Event Triangulation” SIMS3 can pinpoint the location of unknown sources and determine their contribution to the complaints received
A typical construction site requires approximately 4-8 air quality monitoring devices strategically stationed around the site perimeter based on collected data and project size.
Track the impact of upset conditions, odour filter maintenance, sludge deliveries and other on-site events using our SIMS3 AI algorithm
Several on-site activities may be directly contributing to errant odours. SIMS3 can track the emission rate of all odour sources using amient monitors and reverse dispersion modeling.
Once odour complaints are filed, SIMS3 will collect them and visually present them in a visual, mappable format. SIMS3 will also analyze the contributor of the source that led to the complaint.

How Can Scentroid Help with
Construction Site Air Quality and Odour Complaints?
Once you activate Scentroid’s devices and enter our software SIMS3, we can use the collected data to determine whether an odour complaint is justified or not. We identify where the great odour sources come from and make justification for you. We also continuously monitoring to help facility maintain better air quality to avoid receiving complaints.
Odour Complaint Justification
Once Scentroid devices are all set and receive all data, SIMS3 will determine whether an odour complaint is justified or not. Red indicates that the complaint was automatically categorized as “justified”, those in green would be recorded, but categorized as “not justified,” those in yellow would be recorded and categorized as “to be justified”. Furthermore, the user can use triangulation to determine the source of unjustified odours.
Triangulation of Unknown Sources
If you are trying to determine the location of potentially unknown sources, SIMS3 offers a triangulation mode and identifier to assist you with pinpointing unknown sources. SIMS3 features the ability to perform triangulation from odour events or from ambient air monitoring equipment readings.
Odour Complaint Analysis
SIMS3 features a correlation module that determines what events caused the greatest odours and what the contributing sources may have been. Furthermore, should your facility’s process events be recorded, SIMS3 will associate those events with odour increases.

A comprehensive site overview. Scentroid will formulate a sampling plan and, using a team of qualified engineers and technicians, take analytical and olfactometric measurements and samples at key locations. Scentroid analyzes samples on-site using portable analyzers and olfactometers before being shipped to a comprehensive analytical (ISO 17025) and stationary olfactometric laboratory (EN13725). After analyzing the samples the data goes through post-processing, and is compared against pertinent regulations, guidelines and standards. If exceedance of pollutants is found, Scentroid can recommend suitable approaches in order to fulfill environmental compliance. Optional: atmospheric dispersion modelling can be included in the environmental impact assessment.
Determine the severity and extent of the pollutant / odour emissions from your facility. Simulations are processed using the US-EPA designed and approved, AERMOD modelling suite.
Send us your sample bags and our Olfactometric Laboratory will determine their odour concentration in accordance to EN13725:2022, ASTM E679-04, NVN2820, VDI 3881, GB/T14675-93 and/or AS 4323.3.
