Selective Demolition Niagara Falls

A complete quote identifies the removal limits, retained-work protection, service isolation assumptions, temporary support, equipment and access, debris handling, disposal, dust controls, working hours, and turnover condition. Harrowgate also lists required owner information, such as designated-substance reports, structural details, shutdown approvals, and any salvage items that require special handling.

Yes. Harrowgate phases work around approved access and shutdown windows, builds separation from occupied areas, controls dust and noise at source, protects air pathways and circulation routes, and removes debris through a defined route. The plan is coordinated with facility operations, life-safety requirements, security, and the construction schedule before intrusive work begins.

We review records, trace systems in the field, scan where appropriate, make test openings, and obtain positive confirmation of isolation before removing supports or surrounding construction. Services are disconnected, drained, capped, locked out, or protected according to the approved plan. Unidentified lines trigger a hold point, not an assumption based on appearance.

Yes, when salvage is identified in the contract scope. We label items, document condition, disconnect them using the planned sequence, and move them to the designated on-site handover or storage location. Salvage requires more time than waste removal because fasteners, finishes, wiring, rigging points, and packing must be handled without destructive shortcuts.

An interior strip-out usually removes most finishes and systems within a defined suite or floor. Selective demolition can be much narrower or more structural, such as one wall opening, part of a slab, a machine base, or a roof curb. Its defining requirement is precision at the interface between removed and retained construction.

We first reduce uncertainty through drawings, surveys, scanning, and agreed test openings. The quotation then states what is included and identifies assumptions for concealed construction, inaccessible services, hazardous material, and structural support. If an undocumented condition appears, we record it at a hold point so the project team can decide before additional work changes the scope.

Harrowgate removes loose debris, projections, and identified abandoned components, segregates waste streams, and leaves the area safe and accessible for review. The exact turnover can include saw-cut edges, capped services, exposed substrates, temporary protection, survey information, and photographs. Acceptance criteria are defined before work so the next construction activity can start efficiently.

Limits are transferred from issued drawings to field marks and checked against structure, services, finishes, and probes. Sawcuts, dismantling lines, support, and piece sizes are reviewed before removal, with hold points at concealed interfaces.

Work stops at a safe boundary, the item is protected and documented, and the responsible designer or owner determines whether it is retained, isolated, rerouted, supported, or added to the removal scope.
