Project fit: which jobs this service is for
This service is intended for full-house foundations, basement and footing excavations and other substantial construction-scale foundations where coordinated earthworks, site access and material handling are required. Projects should have prepared construction drawings or engineer directions and a defined scope that addresses excavation extents, subgrade elevations and backfill specifications.
We do not take on small landscaping digs, single post holes, isolated drainage repairs or ad-hoc short-duration machine-hour jobs. If your project requires integrated site preparation, export/import of material and coordination with multiple trades, it fits a construction-scale foundation excavation scope.
What we need from your project team before bidding
An accurate bid and workable schedule depend on clear inputs from the design and construction team. The following items are commonly requested during pre-bid and mobilization so we can define scope, material quantities and sequencing.
- Construction drawings showing footing, basement and slab elevations plus structural notes
- Geotechnical reports or soil investigation logs, if available
- Site access plan, staging areas and vehicle routing for import/export of materials and spoil removal, including any municipal restrictions known to the client team
Sequencing and typical site workflow
Work generally follows a coordinated sequence: clearing and protective measures, layout and control, topsoil stripping where required, excavation to subgrade, temporary shoring or benching where specified, and subgrade preparation with dewatering as needed. Each step depends on the agreed scope and site constraints.
Final steps before foundations are ready include verification of subgrade by the project engineer, placement of granular sub-base or rock pads where specified, and preparation for inspection by the project team. Scheduling must accommodate adjacent trades and local municipal inspection windows when applicable.
Bedrock and difficult ground: coordination and methods
Encountering bedrock or very dense strata changes excavation methods and cost. Where rock removal is anticipated, the project team should provide geotechnical information and indicate tolerances on the drawings. Rock can often be removed by mechanical rock excavation or controlled rock-removal techniques; specific methods are determined after review.
Some projects require coordination with specialized rock-removal partners for controlled operations. Any such coordination, scheduling and safety planning will be defined during site review and included in the proposal as a separate line item if required.
Backfill, material handling and temporary works
Backfill and compaction strategy are integral to foundation performance. We work from structural and civil specifications to place specified granular layers, control compaction by testable lifts, install drainage layers or waterproofing protection boards as directed, and manage stockpiles and spoil export responsibly.
Material handling includes segregation and documentation of excavated material, decisions on reuse versus off-site disposal, and temporary erosion and sediment controls during the earthworks period.
- Typical backfill items: specified granular fill, native reuse where acceptable, and engineered compaction lifts
- Temporary works: shoring, bracing or battering as indicated on drawings, and erosion-control measures
- Material handling options: on-site reuse, export to approved facilities, or import of engineered fill per project specifications
Scope limits, service-area clarity and the next practical step
We focus on substantial foundation excavation for new construction projects in the Ottawa region and surrounding markets. Small residential maintenance tasks, isolated post-hole work or simple garden excavations fall outside this service offering. For projects that require specialized urban permitting or utility relocations, the project team should confirm municipal requirements early.
Next practical step: provide construction drawings, geotechnical data and a clear site-access plan so we can arrange a site review and prepare a scoped proposal that identifies assumptions, exclusions and any third-party coordination needed.

Frequently asked questions
How long does a typical foundation excavation take?
Duration depends on scope, site access, ground conditions and backfill requirements. Timelines are provided after plan review and a site visit so sequencing and any necessary third-party coordination can be integrated into the schedule.
Do you handle sites with bedrock?
Yes, we assess bedrock risk from geotechnical data. Where specialised rock removal is required, we coordinate with appropriate partners and include the methods and costs in the proposal following site review.
Will you manage utility locates and shutdowns?
We coordinate around known utilities and work with the project team to confirm locates. Responsibility for utility shutdowns and approvals should be confirmed by the client or project manager during pre-mobilization planning.
Do you take small backyard or single-post excavation jobs?
No. This service is for construction-scale foundation and major site-preparation work. We do not undertake small backyard digs, single post holes, garden work or isolated short-duration machine-hour jobs.
Where are you based and do you serve Ottawa?
The company is based in Val-des-Monts, Quebec, and undertakes construction-scale foundation excavation work in the Ottawa region subject to project fit, access and scope review.
