Subdivision Servicing Richmond Hill

We establish survey control, clearing limits, erosion controls, topsoil stockpiles, excess soil procedures, temporary drainage, haul routes, and the earthwork platform for safe linear production. Deep sanitary and storm systems proceed from approved outlets upstream, followed by watermains and shallower utilities. Crossings, maintenance holes, chambers, and service connections are surveyed before backfill.

The governing document set is the Planning Act approvals and subdivision agreement, current municipal engineering criteria, applicable OPSS and OPSD documents, O. Reg. 406/19, O. Reg. 213/91, and utility-owner standards. Subdivision work follows the registered and approved engineering drawings, subdivision agreement, municipal design criteria, applicable OPSS and OPSD standards, and utility-owner requirements.

The price responds to serviced area, pipe sizes and depths, external upgrades, earthwork balance, groundwater, soil export, rock, trench support, road lengths, utility coordination, phasing, testing, and municipal requirements. Utility crossings designed in isolation cause field conflicts. Composite utility drawings, test holes, and coordinated profile checks establish horizontal and vertical corridors.

The controlling schedule factors are registration and approvals, external outlets, utility relocations, earthworks season, deep sewer production, watermain testing, road-base release, concrete and asphalt seasons, authority inspections, and phased acceptance. We establish survey control, clearing limits, erosion controls, topsoil stockpiles, excess soil procedures, temporary drainage, haul routes, and the earthwork platform for safe linear production.

Yes. Extensions beside occupied employment lands or existing roads use phased connections, temporary access, traffic control, bypass or shutdown plans, and daily coordination with affected facilities and authorities. Incomplete testing packages delay municipal acceptance. We maintain phase-based test registers and correct sewer, water, grading, concrete, and road deficiencies while access remains available.

We compile survey and as-built data, soil tracking, density tests, sewer leakage and CCTV, watermain pressure and disinfection results, concrete tests, granular and asphalt records, lot grading checks, and deficiency closeout. Subdivision work follows the registered and approved engineering drawings, subdivision agreement, municipal design criteria, applicable OPSS and OPSD standards, and utility-owner requirements.

Provide approved subdivision and engineering drawings, agreement requirements, geotechnical and environmental reports, quantity schedules, utility plans, external-work scope, phasing, authority comments, and target releases. Trench backfill, road subgrade, granular layers, curbs, sidewalks, and initial asphalt are constructed with testing and proof rolling at specified stages, while lot grading and swales maintain drainage.

Gravity sewers often occupy the lowest fixed elevations and require continuous grade to an outlet. Installing them first reduces crossing conflicts and allows watermain, shallow utilities, services, and road structure to be coordinated above, while preserving required separation and safe trench geometry.

The program can include sewer leakage tests, CCTV inspection, maintenance-hole review, watermain pressure testing, flushing, disinfection and sampling, compaction tests, structure inspections, survey records, and stormwater commissioning. The issued design, OPSS where specified, utility-owner criteria, and applicable local municipal requirements set the exact acceptance package.
