Phase 2 ESA field support provides the drilling, test pits, monitoring wells, sampling access, utility coordination, soil handling, and site restoration required for an intrusive environmental investigation. Harrowgate executes these field activities across Toronto and the GTA under the Qualified Person's sampling and analysis plan, while the Qualified Person retains assessment, interpretation, and reporting responsibility.
Our phase 2 esa field support sequence starts with verified site information, controlled work zones, and written acceptance points, then moves through field execution, consultant inspection, records, and restoration. We assign each material, asset, sample area, and load a defined status so crews know what can move, what must remain exposed, and who releases the next step.
We review utility records, public and private locates, access restrictions, overhead clearance, pavement thickness, drilling method, target depths, sample sequence, and restoration details. Boreholes are advanced without skipping the consultant's observation and sampling intervals. For test pits, the excavator opens short controlled cuts and presents soil profiles safely without personnel entering an unsupported excavation. Monitoring wells receive the specified screen, sand pack, seal, protective casing or flush mount vault, and development. Coordinates and elevations are surveyed to the project benchmark, and disturbed surfaces are reinstated.
Our field supervisors keep excavation, water handling, trucking, imported materials, survey, and environmental hold points on the same daily plan. We record quantities, load destinations, unexpected conditions, and completed limits as the work advances. That discipline gives the owner and Qualified Person a clean record of what happened below grade, where it happened, and what remains for acceptance.
Materials and acceptance criteria for phase 2 esa field support come from the current Ontario requirements, approved drawings, consultant documents, receiving facilities, and owner standards that apply to the actual site. We check those criteria before procurement or hauling, record field changes, and preserve the evidence required for inspection, environmental review, and future construction.
Ontario Regulation 153/04 Schedule E establishes detailed Phase Two ESA planning, investigation, interpretation, and report requirements. It incorporates CSA Z769 clauses with Ontario modifications and requires soil sampling, with groundwater and sediment sampling where the Qualified Person considers it appropriate. Samples used for regulated work follow prescribed handling and analytical procedures and accredited laboratory analysis. Field quality measures can include equipment blanks, trip blanks for volatile parameters, duplicate samples, clean gloves, dedicated tools, preserved containers, temperature control, and chain of custody.
Ontario Regulation 153/04 governs the assessment and evidence used for many Records of Site Condition. The applicable numerical standard depends on property use, groundwater use, soil texture, depth, and whether the project follows generic or accepted risk based criteria. We execute to the Qualified Person's written criteria and preserve traceability. Ontario Regulation 406/19 and the Rules for Soil Management apply when excavated soil becomes excess soil.
Phase 2 ESA Field Support fails when field production gets ahead of characterization, isolation, inspection, or documentation. Harrowgate prevents that gap with staged work, clearly marked hold points, segregated materials, daily records, and immediate escalation of changed conditions. The goal is to protect people and operations while avoiding rejected loads, concealed deficiencies, repeat excavation, and schedule loss.
Investigation quality drops when drilling crosses utilities, smears contamination between intervals, loses volatile compounds, installs a poor annular seal, or uses an incorrect reference elevation. Rushed restoration can leave unsafe pavement or a damaged well vault. We match tooling and advancement method to the target, decontaminate reusable equipment, contain return water, check material depths as installed, and document refusals or deviations immediately so the Qualified Person can adjust the program before the crew leaves.
We review the next two weeks of work against approvals, sampling, deliveries, shutdowns, and weather. Daily pre work discussions identify the exact limits and status of each area. Photographs and measurements are taken before concealment, and unresolved items stay visible on the field log until the responsible reviewer provides direction or acceptance.

We start with a Qualified Person directs the program, while Harrowgate provides physical field execution. We also confirm access, utilities, operating restrictions, consultant responsibilities, notices, and the intended endpoint. Resolving these items before mobilization lets the field team establish controls, receiving routes, hold points, and contingency space instead of making compliance decisions beside an open excavation.
The main drivers are utility clearance, access, drilling method, target intervals, sampling needs, and restoration. Weather, laboratory turnaround, inspection availability, and working hours can also control production. We build the sequence around the slowest approval or physical constraint and identify parallel tasks that continue without covering work, mixing materials, or compromising a required hold point.
The governing requirements depend on the material, property, equipment, and approval. The work can involve consultant specified screen, sand pack, annular seal, development, protection, and survey. We confirm the current project specific criteria with the engineer, Qualified Person, owner, municipality, or TSSA as applicable. A general industry practice never replaces the written requirement that governs the actual site.
Our field record includes segregated containment pending classification and an authorized management decision. Entries are tied to dates and work areas so quantities and events can be reconstructed. We reconcile documents during the job, not only at closeout, which gives the owner and consultant time to correct a missing ticket, unclear location, or inconsistent quantity before demobilization.
We use tool decontamination, clean handling, blanks, duplicates, preservation, cooling, and custody. Work pauses until the condition is safe, isolated, and assigned a documented response. The supervisor records what changed, where it occurred, who provided direction, and how material or equipment was controlled, preventing an unexpected discovery from contaminating accepted work or disappearing from the record.
Yes, where the design permits it. We plan immediate documentation of refusal, recovery loss, water strike, or utility conflict. The operating boundary, shutdown windows, truck route, emergency access, controls, and daily handback condition are agreed before work starts. Production is staged so facility staff and construction crews do not share uncontrolled access to the work zone.
Closeout should include asphalt or concrete patching, compacted fill, protected wells, and safe final grades. Depending on the project, it can also include photographs, surveys, receiving records, inspection releases, operating logs, test results, redline drawings, and a list of remaining assets. The package supports the owner's consultant and operations team, but professional certifications remain with the appropriately qualified person.
