Services
Underhill & Underhill is a partnership of BC land surveyors providing surveying services to British Columbia and Western Canada from offices in Vancouver, Kamloops, Whitehorse, and Vancouver Island. In operation since 1913, the Underhill team brings deep expertise to many technologies and applications from conventional land surveying to 3D laser scanning.
CADASTRAL SURVEYING
Underhill provides cadastral surveying services (legal land surveying) in British Columbia and Western Canada, Yukon, Northwest Territories, and Nunavut. The firm has a broad range of cadastral surveying expertise for title searches, land acquisitions, property titles and more.
REALITY CAPTURE & 3D LASER SCANNING
Reality capture has many uses within construction, engineering, and digital arts. Highly accurate, as-built 3D models are created from laser scan point cloud data. Digital models are an accurate snapshot of conditions at a point in time and also provide detailed measurement information. 3D laser scanning is a vital part of visual construction documentation, progress tracking, and monitoring.
TOPOGRAPHIC SURVEYS
Topographic surveys support diverse activities across industries, including: the design phase of large engineering and construction projects, land development, land claims exploration, site surveys for development permits, transportation infrastructure mapping and more. Topographic surveys are one of the most requested and recognizable surveying services offered by BC land surveyors.
HYDROGRAPHIC SURVEYS
Hydrographic surveys (marine surveys) are required in the engineering phase of many construction projects on or directly adjacent to waterways. Hydrographic surveys may be used to reveal obstructions beneath the water’s surface, monitor changes, or map the topography of the waterway floor.
CONSTRUCTION & ENGINEERING SURVEYS
Our projects range from single family houses to multi-billion-dollar developments. We work in residential, commercial, and industrial sectors throughout the construction lifecycle. Our large team of professional BC land surveyors can respond rapidly to any construction or engineering survey demands.
RAILWAY SURVEYS
Our railway surveying services are applicable to rapid transit, light and heavy industrial rail. From preliminary railway topography, track layout and construction to final as-built alignment reports, we provide surveying throughout a project’s lifecycle. Underhill works with major rail companies throughout BC and Western Canada.
DEFORMATION MONITORING
Infrastructure must withstand the stresses of load bearing and the environmental in the present and over time. Our deformation monitoring surveys allow engineers to detect changes and implement preventative measures that keep built structures safe while maximizing their lifespan.
AERIAL SURVEYS
Aerial surveying services include drone-borne photogrammetry and 3D laser scanning, including both data capture and visualization (e.g. topographic maps, point clouds, 3D models). Aerial surveys are often used for mapping and the management of land and natural resources.
3D MODELING & BIM
Underhill team uses the latest 3D laser scanning, digital measurement, and reality capture technologies to record an object’s measurement data. Our 3D modeling experts may then create accurate, digital representations of the real-world source, most often used to manage and monitor assets.
FIRST NATIONS SURVEYS
Underhill is very active in the survey and demarcation of the boundaries of Indigenous claims. For decades, we have been involved in many historic land claims in Northern Canada and have become a trusted resource for our First Nations partners.
BOMA & LEASE SURVEYS
Underhill provides BOMA surveys (lease surveys) which adhere to Building Owners and Managers Association standards. Our team of BC land surveyors understands the details of BOMA standards, how they are applied, and how data is best delivered for measurement reports.
VISUAL DOCUMENTATION
Visual documentation has become an integral part of construction and infrastructure management, and asset documentation. Underhill offers many visual documentation services, including 360° panoramic photography for virtual tours, 3D laser scanning, and point cloud modeling.
