Site Servicing Toronto

A package includes watermain, sanitary sewer, storm sewer, services, valves, hydrants, maintenance holes, catch basins, utility crossings, excavation, shoring, dewatering, bedding, backfill, testing, survey, road base, curbs, paving, landscape restoration, and closeout. Harrowgate defines the exact limits from civil drawings and municipal agreements.

Sequence is established from depth, downstream controls, crossings, separation, access, temporary flows, and the approved utility composite plan. Deep gravity sewers often control, but site conditions and tie-ins decide the actual order. Harrowgate builds a coordinated sequence and verifies each crossing elevation before surrounding work removes access.

Acceptance follows the owner’s requirements and includes approved materials, inspection, restraints, pressure and leakage testing, flushing, disinfection, sampling, valve and hydrant checks, tracer-wire verification, records, and authorized connections. Applicable contracts use applicable current the applicable local municipal specification and related procedures. Harrowgate manages the required sequence and corrective work.

Harrowgate protects trench bottoms from disturbance and water, removes unsuitable material, installs uniform bedding, fills haunches, keeps pipe on line and grade, and compacts pipe zone and backfill evenly in controlled lifts. Density and survey checks occur before surface construction. Structures receive stable bases and staged frame adjustment at final grade.

Yes. Harrowgate coordinates temporary roads, crane and delivery access, building connections, fire routes, shutdowns, testing, backfill, and permanent surfaces with the master schedule. Installed utilities are protected from heavy traffic and sediment. Temporary terminations are sealed and identified, and each phase has a defined operating and inspection boundary.

Provide approved civil plans and profiles, utility composite, geotechnical report, municipal agreement and standards, permits, quantity schedule, material requirements, tie-in details, traffic and erosion plans, testing, soil management, phasing, restoration, and closeout requirements. Harrowgate checks the whole corridor so crossing and staging costs are visible.

Harrowgate records horizontal position and elevation for mains, services, structures, valves, hydrants, fittings, bends, restraints, crossings, stubs, and tie-ins as required by the owner. Records also include material, testing, inspection, and connection data. Survey is captured while assets remain visible, improving accuracy and reducing later investigation.

The deepest gravity service often leads, but downstream connections, crossings, groundwater, access, temporary drainage, utility-owner constraints, and construction phasing determine the actual sequence.

Typical records include as-built survey, pipe and structure data, material certificates, inspection releases, pressure and leakage tests, disinfection and sampling results, CCTV where specified, compaction tests, connection records, and restoration acceptance.
