Parsways Inc. provides professional engineering services for eligible underpinning and existing foundation projects in British Columbia.
​
Our work supports architects, building designers, builders, contractors, property owners, and project teams requiring engineering input for foundation strengthening, basement lowering, modifications to existing foundation walls, or permit-related underpinning documentation.
​
Parsways Inc. is registered with Engineers and Geoscientists BC and holds a Permit to Practice for professional engineering services in British Columbia.
​
Accepted underpinning projects are completed under the responsibility of an EGBC-registered professional engineer and within the applicable scope of practice, code requirements, available site information, and project-specific authority requirements.
Underpinning Engineering for Existing Foundations
Our British Columbia underpinning engineering services may include review of submitted existing foundation information, design of underpinning elements, foundation deepening details, basement lowering support, load-transfer review, underpinning sequence notes, structural drawings, permit-related details, and responses to authority comments.
​
Depending on the project, engineering input may also address localized foundation strengthening, support of existing walls during foundation modifications, connections between new and existing foundation elements, and coordination with geotechnical recommendations or contractor-proposed construction methods.
​
The final engineering scope is determined after reviewing the existing structure, proposed work, available drawings, photographs, measurements, soil information, and intended construction sequence.
Engineering Basis for Underpinning Projects
Underpinning design for British Columbia projects is completed with reference to the applicable British Columbia Building Code, municipal requirements, relevant structural standards, and project-specific site conditions. Projects located in the City of Vancouver may be subject to the Vancouver Building By-law and Vancouver-specific submission requirements.
​
Because underpinning can affect existing load paths, foundation bearing, excavation limits, adjacent construction, and temporary stability, additional information may be required before the design can be finalized.
​
Depending on the project conditions, this may include geotechnical recommendations, survey information, local site verification, groundwater information, confirmation of existing foundation dimensions, or temporary shoring information prepared by the appropriate project party.
Underpinning Review Process
Parsways reviews underpinning projects in British Columbia remotely using available drawings, photographs, measurements, geotechnical information, contractor methodology, and authority comments.
​
This review helps confirm the proposed scope, identify missing information, and assess whether the project can proceed based on the submitted documents.
​
Existing foundation conditions, excavation depth, underpinning layout, adjacent structures, bearing conditions, and construction sequence may need to be confirmed. Where field verification is required, suitable local arrangements must be included in the project scope.
Common Underpinning Project Types
Parsways may support eligible residential, commercial, and light industrial underpinning projects across British Columbia, including projects in Vancouver, Burnaby, Richmond, Surrey, Coquitlam, Victoria, Kelowna, and other BC municipalities upon review.
​
Common requests may include engineering for basement lowering, foundation deepening, crawlspace conversion, localized foundation stabilization, support of existing walls during renovation, underpinning associated with additions or structural alterations, and foundation modifications where existing bearing elevations or load paths are changing.
Request an Underpinning Engineering Review
To request an underpinning engineering review for a British Columbia project, please send the project address, available existing and proposed drawings, photographs of the foundation, relevant dimensions, proposed excavation or lowering depth, available geotechnical information, contractor methodology, and any municipality comments.
​
Once the information is reviewed, Parsways can confirm the required documentation, missing project information, applicable engineering scope, and next steps.
