Excavation Contractor

Harrowgate requires issued drawings, survey control, geotechnical information, valid utility locates, environmental and soil direction, access and haul plans, shoring design, groundwater strategy, permit conditions, disposal or reuse destinations, testing requirements, and restoration limits. Critical services are daylighted where required before production excavation reaches their zone.

Selection follows O. Reg. 213/91, identified soil type, depth, groundwater, surcharge, nearby structures, utilities, vibration, available space, and the engineer’s design. Harrowgate installs and works within the approved system. A slope that appears stable in dry weather is not treated as proof that support requirements can be ignored.

Harrowgate stops at the identified condition, surveys and documents the affected area, protects it from further disturbance, and obtains the engineer or geotechnical consultant’s direction. Correction uses the specified concrete, engineered fill, granular, or other detail. Unapproved loose soil is not placed back beneath a footing, slab, pavement, or utility.

Soil is characterized, tracked, reused, stockpiled, transported, or delivered under the project’s soil-management plan and applicable Ontario excess-soil requirements. Harrowgate keeps source areas and material streams separated, uses approved receiving destinations, maintains load and quantity records, and prevents suspect or contaminated material from being blended into clean fill.

Final cuts are sequenced close to inspection and construction. Harrowgate limits equipment disturbance, keeps water and traffic off the bearing surface, removes softened or frozen material, and uses mud slabs, granular protection, insulation, or other specified measures. Bearing review is completed and recorded before forms, concrete, or fill cover the surface.

Yes. Harrowgate phases barriers, access, deliveries, emergency routes, utilities, vibration, noise, dust, haul traffic, and shutdowns with facility operations. Work zones are kept secure, temporary services and crossings follow approved plans, and excavation advances in sections that preserve the agreed operating routes and response access.

Records include locate and daylighting information, survey cuts, soil observations, shoring inspections, groundwater and dewatering logs, truck and destination records, imported material tickets, density tests, proofing and bearing reviews, monitoring results, photographs, quantities, and as-built elevations. Harrowgate organizes them by area and stage.
