Industrial and Heavy-Civil Construction
Execute shutdown, concrete, and civil work without losing control of restart.
Harrowgate Group plans, manages, and self-performs industrial construction across Toronto, the GTA, and Ontario. We build equipment foundations, process slabs, underground services, drainage, roads, yards, and structural concrete, with demolition, excavation, reinstatement, inspections, and turnover sequenced around live plants and fixed shutdown windows.
Industrial concrete built for equipment, traffic, and process loads
Industrial concrete has to transfer real loads, control movement, and meet the installation tolerance of the equipment it supports. Harrowgate constructs complete industrial concrete packages, including foundations, pits, trenches, housekeeping pads, suspended and ground-supported slabs, containment areas, loading zones, and machine bases and equipment pads. We coordinate excavation, subgrade improvement, forming, reinforcing, embeds, anchor layouts, concrete placement, finishing, curing, and backfill.
The work is built from issued drawings, equipment vendor data, geotechnical recommendations, and project specifications. Concrete supply and execution follow applicable CSA A23.1 requirements, while testing is coordinated to the specified CSA A23.2 methods. Survey control verifies lines, elevations, anchor locations, slopes, and interfaces before the next activity starts. For high-wear areas, the placement plan addresses joint layout, finishing class, abrasion exposure, chemical exposure, drainage, and the required time before loading.
Heavy-civil scope from earthworks to operating utilities
Industrial expansions and rehabilitations depend on civil work below the finished surface. Harrowgate performs mass excavation and bulk earthworks, shoring and trench support, cut and fill, engineered granular placement, compaction, site grading, storm drainage, road base, paving, and restoration. We also install and replace sanitary sewers, storm sewers, and watermains for industrial sites.
Before work reaches existing infrastructure, we review records, confirm locates, expose critical crossings, and plan tie-ins around isolation and plant demand. Pipe bedding, embedment, structures, thrust restraint, testing, flushing, backfill, and surface restoration follow the approved design, applicable OPSS requirements, and local authority standards. Dewatering and temporary drainage are planned before excavation so changing groundwater or rainfall does not undermine the trench, delay the tie-in, or contaminate prepared subgrade.
Shutdown planning starts with the restart condition
A shutdown schedule is built backward from the condition required to restart. Harrowgate separates pre-shutdown enabling work from outage work, confirms access and lifting constraints, and identifies hold points for demolition limits, excavation, reinforcing, embeds, pressure testing, concrete acceptance, and equipment release. Materials, equipment, disposal capacity, survey support, testing, and backup methods are confirmed before the outage begins.
During execution, production interfaces and critical-path activities are reviewed daily. Selective demolition exposes the next work face without damaging retained assets. Excavation, base preparation, underground work, concrete, and reinstatement advance in the required sequence, with protection maintained around live services and operating areas. Turnover confirms that tests, inspections, deficiencies, housekeeping, temporary works, and access restoration are complete before the area returns to the plant.
Controls and records that stand up at turnover
Industrial quality control has to be visible while the work is open. Harrowgate tracks approved drawings, field changes, inspection requests, concrete delivery tickets, test results, survey checks, compaction results, pipe testing, and deficiency closeout against the installed scope. Work requiring a building permit is coordinated with the applicable 2024 Ontario Building Code requirements and municipal inspections. Civil work is checked against the issued specifications, OPSS references, and approved details.
Durability decisions reflect the exposure. Exterior concrete needs drainage, air entrainment where specified, properly detailed joints, and curing protection through Ontario temperature swings. Process areas need compatible repair materials and coating preparation. Loading docks and industrial ramps need positive drainage, impact-resistant edges, stable base, and pavement transitions that tolerate repeated truck loading. These details prevent early failure at the interfaces where industrial assets receive the most punishment.
One construction plan across the plant and the site
Harrowgate manages industrial work as an integrated construction package, not a collection of disconnected activities. Concrete elevations match process and drainage requirements, underground routes clear foundations, road grades meet loading areas, and restoration follows completed tie-ins. Our project team coordinates directly with plant operations, owners, engineers, equipment vendors, and inspectors while our field crews self-perform the core concrete and heavy-civil work.
This approach is especially effective for additions, line changes, yard expansions, utility renewals, dock reconstruction, and commercial and industrial demolition where the sequence crosses multiple disciplines. Harrowgate Group is licensed, insured, and WSIB certified, with active-site planning and documented closeout built into every industrial scope.
Scope the work before the shutdown clock starts
Send the issued drawings, equipment requirements, site records, outage dates, or performance problem. Harrowgate will define the construction sequence, identify operating constraints, and quote the industrial concrete, civil, underground, demolition, and restoration work required.
