What Annis O’Sullivan Vollebekk does

Annis O'Sullivan Vollebekk Ltd. (AOV) is a privately-owned, independent professional land surveying firm headquartered in Nepean, Ontario, with regional offices in Embrun and Kemptville. Founded in 1964, the firm provides licensed cadastral, geodetic, engineering, construction layout, condominium, land severance, residential, utility, and highway surveys to developers, construction firms, government agencies, utilities, lawyers, and individual property owners in Eastern Ontario, with selected work in the James Bay area and the Caribbean.

Technically, AOV operates a Trimble-centered geomatics stack — TSC7 controllers, Trimble GNSS, and Trimble Total Stations — augmented by UAVs for aerial LiDAR and photogrammetry, terrestrial LiDAR scanners for as-built and deformation work, and unmanned surface vessels (USVs) for bathymetric topography. Post-processing is performed in-house by Ontario Land Surveyors, engineers, and technologists using AutoCAD, MicroStation, and MicroSurvey software, allowing the firm to deliver digital terrain models, GIS consulting outputs, and Surveyor's Real Property Reports that comply with the Ontario Surveys Act. Notable project references include the second-order H&V control network for the Ottawa Light Rail Transit, surveying of 40+ km of track at CNR's Walkley Yard, and boundary/LiDAR work on a 300-hectare warehousing development near Cornwall, ON.

Commercially, AOV runs a sales-led professional services model with quote-based project pricing, multi-office direct consultation, and a referral-driven top-of-funnel generated through AOLS membership, the Greater Ottawa Home Builders' Association, the Prescott-Russell Chamber of Commerce, and a documented base of returning developers and government clients. The firm is led by three partners — V. Andrew Shelp (President, since 1986), Travis Hartwick (Vice President, partner since 2019), and Edward H. Herweyer (Secretary-Treasurer, partner since 1989) — supported by a Director of Operations, an HR Manager, and dedicated office managers; two partners have held the presidency of the Ontario Land Surveyors Association. The firm has no disclosed external funding, no parent company, and no acquisition history in the available record.
