Our Process

How the commercial and industrial site development process works

  1. 1. Initial contact and request for quote. The first commercial and industrial site development conversation covers the property, deadline, access, and records needed to determine how to establish survey control and protect existing operations.
  2. 2. Drawings, site review, and scope confirmation. Surveys, reports, drawings, and specifications are checked against the commercial and industrial site development area to clarify how to balance earthworks without trapping drainage around Site Servicing.
  3. 3. Detailed quote and clear assumptions. Pricing for commercial and industrial site development names the sequence, controls, materials, handover, and assumptions tied to the need to sequence utilities ahead of roads and slabs.
  4. 4. Engineering, consultant, and municipal coordination. Before commercial and industrial site development starts, Harrowgate coordinates drawings, approvals, and hold points with structural and civil engineers, architects, consultants, utilities, and the applicable municipality.
  5. 5. Mobilization and site execution. Mobilization for commercial and industrial site development follows the access and protection plan, sequencing resources to release subgrade and granular layers from testing where Site Grading And Earthworks meets the work.
  6. 6. Inspection, testing, and documentation. During commercial and industrial site development, inspections, measurements, material data, tests, and photographs confirm the work and allow the file to coordinate curbs, inlets, pavements, and landscaping.
  7. 7. Closeout and handover. Closeout for commercial and industrial site development covers review, deficiencies, cleanup, restoration, and records documenting how the scope will close erosion controls only after stabilization. The St. Thomas service-area hub lists commercial and industrial site development coverage.

Why Us

Why choose Harrowgate for commercial and industrial site development

Harrowgate's 20 years in business gives commercial and industrial site development clients an experienced point of accountability from scope review through handover. The value is concrete: the team knows why it must establish survey control and protect existing operations, when it should balance earthworks without trapping drainage, and what evidence belongs in the project record.

Rather than leaving commercial and industrial site development coordination between separate contacts, Harrowgate maintains one accountable team for the client. Structural and civil engineers, architects, consultants, utilities, and municipalities receive the questions needed to coordinate curbs, inlets, pavements, and landscaping, including those affecting Roadworks And Pavement Base and Stormwater Management And Drainage.

Harrowgate Group and every trade partner on the project is fully licensed, insured, and WSIB-covered.

Clear scope language, documented hold points, and direct reporting keep commercial and industrial site development decisions visible to the client. If the project needs to close erosion controls only after stabilization, call (416) 629-0721 or send Harrowgate the drawings and site information.

Understanding site development

Which site development method fits the project? by Harrowgate Group

Which site development method fits the project?

Greenfield development, brownfield redevelopment, occupied-site expansion, phased pad construction, and full site reconstruction require different investigation and sequencing. Work may combine clearing, removals, earthworks, soil management, utilities, stormwater systems, curbs, concrete, granular base, paving, hardscape, and landscape preparation. The correct plan follows the site's water, soil, access, utility, and operational constraints rather than treating each trade as an isolated package.

How we deliver commercial and industrial site development by Harrowgate Group

How we deliver commercial and industrial site development

Step 1,

Step 2, Topsoil and unsuitable material are segregated, cut and fill is balanced where specifications permit, and proof rolling or geotechnical review identifies weak subgrade before imported granular is placed.

Step 3, Sanitary, storm, water, electrical duct banks, chambers, maintenance holes, catch basins, and building services are installed from downstream and low elevations with testing and survey completed before backfill.

Step 4, Road base, curbs, slabs, paving, line marking, landscaping interfaces, and permanent drainage are completed in a sequence that preserves clean access and protects tested underground systems.

Step 5, Final grading, drainage, pavements, utilities, stabilization, structures, markings, and restoration are inspected as one functioning site, with test reports and record elevations assembled before temporary controls are removed.

Materials, specs, and Ontario standards

Site work follows approved civil drawings, municipal standards, applicable OPSS and OPSD documents, O. Reg. 406/19 for excess soil where applicable, and O. Reg. 213/91 excavation requirements.

Commercial and Industrial Site Development requirement 2. Fill type, lift thickness, moisture conditioning, compaction target, proof rolling, and testing frequency come from the geotechnical report and project earthworks specification.

Commercial and Industrial Site Development requirement 3. Pipe material, class, bedding, cover, jointing, structures, valves, hydrants, testing, flushing, disinfection, and CCTV requirements follow the owner and municipal standards for each system.

Commercial and Industrial Site Development requirement 4. Road and parking sections are built to design elevations and crossfall using specified subbase, base, asphalt, or concrete. Survey and density tests verify the layers before surfacing.

FAQ

Site Development FAQ

Which field activities are included in commercial and industrial site development?

Survey control, utility locating, environmental limits, access, erosion and sediment controls, tree or feature protection, and temporary drainage are established before stripping or demolition begins. Road base, curbs, slabs, paving, line marking, landscaping interfaces, and permanent drainage are completed in a sequence that preserves clean access and protects tested underground systems.

Which Ontario requirements govern commercial and industrial site development?

The governing document set is approved municipal engineering criteria, applicable OPSS and OPSD documents, the 2024 Ontario Building Code, O. Reg. 406/19, O. Reg. 213/91, utility owner standards, and the geotechnical specification. Fill type, lift thickness, moisture conditioning, compaction target, proof rolling, and testing frequency come from the geotechnical report and project earthworks specification.

Which site conditions drive the price of commercial and industrial site development?

The price responds to earthwork balance, unsuitable soil, groundwater, disposal and reuse criteria, utility depth and size, rock, shoring, road area, stormwater facilities, traffic access, winter conditions, and authority requirements. Installing services without corridor coordination causes crossings and elevation conflicts. Composite utility review and field daylighting verify routes before production trenching.

Which hold points control the commercial and industrial site development schedule?

The controlling schedule factors are permits, utility relocations, soil and groundwater conditions, haul capacity, weather, dewatering, underground testing, building release dates, concrete cure, paving season, and final authority inspections. Survey control, utility locating, environmental limits, access, erosion and sediment controls, tree or feature protection, and temporary drainage are established before stripping or demolition begins.

How does Harrowgate execute commercial and industrial site development beside active operations?

Yes. Redevelopment and expansion sites are divided into operating and construction zones with temporary roads, barriers, drainage, utility bypasses, delivery windows, and staged turnover planned with the facility team. Uncontrolled surface water saturates subgrade and delays every following trade. Temporary swales, sumps, pumps, stable access, and progressive drainage installation keep the site workable.

Which records verify completed commercial and industrial site development?

We track survey control, excavation and fill quantities, soil tickets, density tests, pipe and structure elevations, leakage and pressure tests, CCTV, concrete tests, granular depths, asphalt records, and final as-built information. Fill type, lift thickness, moisture conditioning, compaction target, proof rolling, and testing frequency come from the geotechnical report and project earthworks specification.

What documents are required to price commercial and industrial site development?

Provide civil, grading, servicing, landscape, electrical, and structural drawings, geotechnical and environmental reports, survey, utility records, approvals, quantity schedules, phasing, access restrictions, and target building release dates. Survey control, utility locating, environmental limits, access, erosion and sediment controls, tree or feature protection, and temporary drainage are established before stripping or demolition begins.

What is normally included in a commercial site-development scope?

A complete scope can include survey control, clearing, demolition, erosion controls, earthworks, soil management, water, sanitary and storm services, stormwater facilities, granular base, curbs, sidewalks, concrete pads, paving, markings, landscaping preparation, testing, and record surveys. The issued drawings and responsibility matrix define the project limits.

How is unsuitable soil handled during site development?

The team identifies the material through proofing, observation, and testing, then defines removal limits and an accepted replacement. Options may include drying, blending where approved, stabilization, engineered fill, granular replacement, geosynthetics, or redesign. Environmental classification and lawful handling remain separate from geotechnical suitability.
