Developing complex, multi-use buildings and intricate infrastructure in Pemberton often demands separating the ownership of volumetric spaces without the constraints of a communal strata corporation. An Air Space Subdivision, governed by Part 9 of the Land Title Act, is a highly specialized legal mechanism that creates one or more 3D "air space parcels" out of a fee-simple parent parcel. Unlike strata lots, an air space parcel is an independent fee-simple title that operates without statutory implied easements for support, shelter, or servicing, and without a legislated governance structure. This makes air space an incredibly powerful tool for developers mixing commercial, residential, and governmental ownership within a single footprint, but it also demands an uncompromising level of legal, spatial, and engineering precision.

As dual-registered British Columbia Land Surveyors (BCLS) and Professional Engineers, our firm delivers the elite geomatics expertise and statutory authority required to seamlessly navigate the air space subdivision process. Under the Land Surveyors Act, defining these complex volumetric boundaries is the exclusive right of a commissioned BCLS. We work intimately with your development lawyer, engineer, and architect to ensure that the physical boundaries we define on the Air Space Plan perfectly align with the complex Air Space Agreement, a customized suite of registered easements, covenants, and equitable charges required to guarantee that all parcels have secure rights for access, structural support, and utilities.

Because the upper and lower limits of an air space parcel must be defined by horizontal or inclined planes (or arcs of a circle) using exact geodetic elevations, we employ a state-of-the-art suite of geomatics instruments. We utilize Aerial Drone Photogrammetry and Drone LiDAR during the initial site mapping to generate flawless 3D terrain models. We then occupy points with Static GNSS Receivers and RTK GNSS Receivers to tie your project precisely into the provincial horizontal and vertical datums mandated by the Surveyor General. Inside the complex building superstructure where satellite signals are entirely obstructed, we transition to millimeter-accurate Robotic Total Stations and Terrestrial LiDAR (3D laser scanning) to capture high-density point clouds of the as-built conditions. This uncompromising precision ensures your Air Space Plan flawlessly represents the physical reality of your multi-million dollar development in Pemberton.

How do we ensure accuracy and efficiency in our land surveying projects?

We follow a structured, transparent process to deliver precise results and keep your project on schedule.

Step 01

Research

Before any volumetric boundary can be designed, the BC Land Surveyor conducts exhaustive documentary research. We extract current titles, historical subdivision plans, and registered encumbrances from the Land Title and Survey Authority of British Columbia (LTSA). A critical part of the BCLS's role is reviewing the parent parcel to guarantee it complies with Part 9 of the *Land Title Act*, ensuring that the land is registered in the register of indefeasible fees and shown as a single parcel. We also meticulously review the draft Air Space Agreement to verify that the proposed boundaries match the planned easements and legal framework.

Step 02

Field Work

The field work for an air space subdivision requires extreme precision and strategic timing. To define the vertical limits, our crews use GNSS technology to establish highly robust vertical control, setting a minimum of two permanent, vertically stable bench marks within 500 meters of the air space parcel as legally mandated by the ABCLS *Survey and Plan Rules*. Using Robotic Total Stations and Terrestrial LiDAR, we measure the physical features of the building to define the side, upper, and lower limits. The progress of construction heavily impacts the scope and time to completion; if an air space boundary is designed to be located within a specific wall, floor, or ceiling, it is highly recommended that this structure be built before the final field measurements are taken to eliminate the risk of spatial conflicts.

Step 03

Plan Preparation

Our drafting experts translate the dense 3D field data into the highly regulated Air Space Plan format. In accordance with the *Survey and Plan Rules*, the plan must include a plan view, isometric (3D paraline) views, and cross-sections to unambiguously illustrate the volumetric boundaries. The BCLS assigns a unique number or letter to every corner of the air space parcel, providing a clear reference across all views and within the plan's volumetric book of reference. As the certifying professional, the BCLS electronically signs the Survey Plan Certification (SPC) using a secure digital certificate. Once the municipal Approving Officer endorses the plan, the complete package is submitted to the LTSA, where the Registrar reviews and deposits the plan and raises the new indefeasible titles.
