Our Process
How we plan and deliver internal bracing and rakers
Internal Bracing and Rakers is temporary steel compression systems installed inside an excavation to restrain shoring walls when external anchors are unavailable, restricted, or unsuitable. Harrowgate Group performs this work directly on commercial, industrial, and heavy-civil sites in Toronto and the GTA, with controlled field execution and documented handoff.
- 01 Send your inquiry, a few photos or a description of the site.
- 02 We come out, assess the site, take measurements, and confirm the scope.
- 03 We complete the internal bracing and rakers on site, to the load and finish the job needs.
- 04 We install it, finish to grade, and clean up, one accountable crew, start to finish.

Scope
Understanding internal bracing and rakers
How we perform internal bracing and raker installation
We execute internal bracing and raker installation through a verified sequence with clear release points between activities. Existing conditions, isolations, access, temporary stability, material destinations, and required inspections are confirmed before production advances. The supervisor keeps each work face in a safe, known state when the crew changes tasks or encounters a variance.
Our working sequence is to coordinate the brace layout with excavation, cranes, ramps, and permanent construction, install connection brackets and walers at the design elevation, prepare thrust blocks or foundations for rakers, lift and connect struts or rakers, align and preload where specified, excavate beneath the completed tier, add lower tiers in sequence, monitor loads and movement, then transfer wall forces into permanent slabs before staged removal.
The sequence is translated into daily work packs with prerequisites, access routes, inspection points, crew assignments, and the condition required at shift handoff.
We select equipment for the real task and working envelope, including mobile cranes, telehandlers, structural steel walers and struts, pipe braces, hydraulic jacks, load cells, welding equipment, bolting tools, survey instruments, and concrete equipment for thrust blocks. Equipment capacity is checked against load, reach, ground bearing, headroom, travel route, material characteristics, and the planned production rate. We stage attachments, consumables, containers, backup pumps, and critical spares before a constrained shift or shutdown begins.
Field control is built around member grade and size, connection geometry, weld and bolt inspection, waler continuity, brace slenderness, thrust block capacity, preload, temperature effects, accidental impact protection, excavation lift limits, measured movement, and an engineered removal sequence tied to permanent concrete strength.
Supervisors record progress and conditions at each shift, compare them with the issued plan, and stop advancement when the next prerequisite is not proven. If hidden construction, changed soil, unknown services, unexpected contamination, or an access conflict appears, we stabilize the area and obtain the required direction before changing the method.
Materials, specs, and Ontario standards
Internal Bracing and Rakers must follow the issued project documents and the Ontario requirements applicable to the workplace, hazards, materials, and temporary or permanent works. We track dimensions, capacities, tolerances, test values, and acceptance criteria to their approved source, then collect field records that show what was installed, removed, tested, and shipped.
The principal compliance and specification framework includes O. Reg. 213/91 engineered support requirements, OBC structural and excavation provisions, CSA S16 structural steel design and fabrication requirements, CSA A23.1 for concrete thrust blocks and permanent interfaces, and engineer sealed temporary works drawings. We confirm which provisions apply to the project status and scope instead of mixing requirements from unrelated work types.
We check current issued-for-construction drawings, specifications, addenda, permits, utility information, and owner procedures before procurement or installation. Material certificates, concrete or grout tickets, equipment inspection records, calibration information, waste profiles, and test forms are collected as the work requires. A field change is not buried in a daily report. It is identified, reviewed, and recorded against the approved basis.
Ontario requirements depend on whether the location remains an industrial establishment or has become a construction project, and on the hazards actually present. We apply the project’s designated-substance information, confined-space assessment, demolition or shoring engineering, waste classification, excess-soil rules, and municipal discharge conditions as applicable. We never assume that an owner’s internal permit replaces the governing legal or engineering requirements.

FAQ
Internal Bracing and Rakers FAQ
What information do you need to quote internal bracing and raker installation?
We need the site address, current drawings and reports, approximate quantities, required endpoint, access limits, operating restrictions, known hazards, utility status, target schedule, and required records. A site walk lets us verify equipment access, staging, retained assets, public interfaces, and the conditions that will drive the work plan.
How do you plan internal bracing and raker installation around an operating facility?
We divide the work into clearly released areas or systems, confirm isolations before each shift, protect emergency routes and retained services, and schedule disruptive activities inside approved windows. Daily coordination covers access, noise, dust, water, traffic, permits, and handback conditions so operations know exactly what changes and when.
Who provides the engineering and technical acceptance criteria?
The owner’s retained engineer or consultant normally defines design and acceptance requirements where professional input is required. Harrowgate coordinates constructability, field measurements, installation records, testing, and requests for direction. We do not alter an engineered sequence or acceptance value informally. Changes are reviewed and documented before the affected work advances.
How are unexpected site conditions handled?
We stop the affected activity, leave the area stable, record the condition with measurements and photographs, and determine what information is missing. The project team can then assess the impact and issue direction. Work continues in unaffected areas where practical, while the changed method, quantity, or destination is resolved and documented.
How do you control waste, water, and removed materials?
We identify each material stream before removal, keep incompatible or differently classified materials separate, select suitable containers and vehicles, and confirm the receiving destination. Water is captured, tested, treated, or transported as the project requires. Tickets, manifests, weights, and load records are reconciled with the originating work area.
What determines the schedule for internal bracing and raker installation?
The schedule depends on quantity, access, shift windows, isolation readiness, engineering hold points, equipment reach, material cure or test times, groundwater or residue conditions, hauling capacity, and receiving hours. We build a production sequence only after those constraints are mapped, then use short look-ahead plans to keep prerequisites ahead of field crews.
What closeout records will the project receive?
Closeout is matched to the specification and may include daily reports, photographs, surveys, inspection forms, test results, concrete or grout tickets, equipment records, waste and recycling tickets, monitoring data, and marked-up drawings. We agree on file names and submission intervals early so records remain useful for progress review and final turnover.
