Commercial Demolition

Commercial building demolition generally requires a municipal demolition permit and supporting plans, specifications, and documentation. The exact submission depends on the structure and site. Harrowgate coordinates its demolition method, utility termination information, environmental reports, protection plan, and engineering inputs with the owner’s permit team before physical building removal begins.

Cost depends on building area and height, structural system, access, adjacent properties, designated substances, service disconnections, foundations, disposal classifications, traffic control, and the required final grade. Harrowgate prices from drawings and a site review, then states material assumptions, removal limits, salvage treatment, and permit-dependent controls so bids can be compared accurately.

Yes, when the retained occupancy and demolition zone can be safely separated. Harrowgate plans independent access, verified services, dust and debris barriers, fire-protection interfaces, delivery windows, noise periods, and emergency routes. Structural separation and temporary weather protection are coordinated with the project engineer and architect before the shared assembly is opened.

Harrowgate sorts structural steel, reinforcing steel, non-ferrous metal, clean concrete, wood, and residual waste into controlled streams. Suitable concrete can be sent to recycling or crushed under a project-specific plan. Load records and scale tickets support waste reporting, while early separation prevents roofing, gypsum, soil, or regulated material from contaminating recyclable aggregate.

Protection begins with a condition review, structural investigation, property and foundation information, and an engineered sequence. Harrowgate controls wall restraint, equipment stand-off, debris fall zones, dust, vibration, truck movement, and weather exposure. Monitoring points and response values are established by the project consultant where required, with readings documented throughout high-risk activities.

Yes. We remove footings, grade beams, slabs, pits, and abandoned services to the limits stated in the contract. The scope defines what stays, cap locations, required excavation elevations, backfill or rough-grade requirements, and survey checks. Ontario One Call and private locates are completed before breaking ground around buried infrastructure.

The schedule includes investigation, permit and engineering reviews, utility disconnections, designated-material removal, mobilization, structural demolition, sorting, foundation removal, and site turnover. Building size alone is not enough to forecast duration. Harrowgate develops production logic around access, trucking, working hours, neighbouring operations, and required hold points, then reports progress against that sequence.

Include current surveys and drawings, designated-substance and environmental reports, utility status, geotechnical information, retained elements, property access, approved working hours, traffic requirements, permit status, waste objectives, foundation-removal limits, backfill specifications, and the final turnover condition. Clear information reduces contingency and exposes scope differences before contract award instead of during demolition.
