Our Expertise
Geotechnical Investigations
We provide subsurface investigations for various types of project sites, including residential subdivisions and towers; infrastructure projects; commercial and industrial developments, and community and institutional projects.
Hydrogeological Assessments
These investigations provide a characterization of the hydrogeology and hydrology of a site, and allow us to provide recommendations for mitigating impacts to surface water features and shallow groundwater conditions.
Excess Soils Management
Disposal of excess soils from project sites now falls under Ontario Regulation O. Reg. 406/19. Since its inception in 2019, the regulation has been updated with various changes to address construction stakeholders comments and feedback.
We can assist you by providing clarity on your project requirements, identifying appropriate acceptance criteria for sites accepting soil, or helping to identify suitable receivers for sites with excess soils to dispose of, to ensure that you are in compliance with the regulatory requirements.
Residential Septic Designs
We typically design residential septic systems in accordance with Ontario Building Code (OBC) Requirements. For larger systems, we can assist with septic designs, and Reasobale Use Assessments required as part of the Ministry of Environment Certificate of Authorization approvals.
Slope Stability
Whether site are located along rivers or streams, or along the lakeshore, or adjacent to existing slopes which may be a hazard, we can complete a site review and detailed slope stability analysis, provide guidance on suitable development setbacks, and provide recommendations for slope remediation.
Phase I & Phase II ESA
The purpose of a Phase I (ESA) is to determine if there is evidence of actual or potential contamination present on a site., by reviewing site conditions and historical research regarding previous activities on or near the subject property. If the desktop study suggests that potentially contaminating activities have led to one or more areas of potential environmental concern at a Site, then a sampling and analysis plan is prepared to conduct the recommended intrusive work (i.e., a Phase II investigati) to verify if contaminants are present in the soil and/or groundwater.
Inspections and Material Testing
We offer a range of inspection and materials testing services, including subgrade reviews, footing base examinations, concrete reinforcing steel inspections, concrete sampling and testing, soils/aggregates testing, compaction testing, and other inspections which support new construction.
Pavement Evaluations
Asphalt pavements are known as flexible pavements, and over time, they can show signs of wear and age. Construction schedules often result in a period of time where surface asphalt placement is delayed. It is important to assess the condition and performance of the base asphalt prior to surface asphalt being placed, to ensure that defects and deficiencies are addressed.
Settlement Monitoring
We are able to provide settlement monitoring programs to assess the effects of construction dewatering, or subsurface excavation work on buildings, structures or other infrastructure. Accuracy and reliability in reporting is key in providing meaningful data, which can help to predict and prevent uncontrolled loss of ground or movement. which can impact the structural stability of foundations and other site features.
Erosion and Sediment Control Inspections
Construction activities ca n significantly alter the landscape of a project site. As earthworks and other excavating activities occur, the risk of uncontrolled sediment release increased, as the amount of disturbed area onsite increases. We can help design suitable ESC controls and provide inspection to document the effectiveness of the measures used onsite.
Designated Substances Survey
Designated and hazardous substance surveys are required for demolition of buildings and structures, to identify the presence of materials which may harm workers, if proper measures are not taken during construction. Site review includes sampling for items such as asbestos and lead paint, which are often present in older structures.
Permits to Take Water
When construction dewatering volumes exceed500,000 L/day, the Province requires that an Environmental Sector Activity Registry (EASR) submission be completed. When volumes exceed 400,000 L/day, a more rigorous permitting process is required for project owners and/or their contractors to obtain a Permit to Take Water, which specifies the terms and conditions for how and when water can be taken, and how it is to be discharged.
