School District 44 – North Vancouver

Underhill has been working with the North Vancouver School District (SD#44) for over 50 years. In the 1950's and 60's Underhill performed topographic and legal surveys of all of the North Vancouver school sites. Most recently these have included the following:

Ridgeway Elementary School

Ridgeway School is a heritage building built in the early 1900's. DA Architects of Vancouver commissioned Underhill to conduct a building extents survey of the entire building facade. Underhill used a Trimble GX 3D scanner to complete the survey. The scan produced a complete rendering of the school exterior in detail that would not be possible using conventional survey techniques. Eleven million points were collected and the 3D data was used to produce 2D elevation views, vertical and horizontal cross-sections and details of individual areas of interest. The point cloud also produced an accurate and complete record of the school conditions for any future reference needed.

Queen Mary Elementary School

After the successful 3D scanner–based survey of Ridgeway School, SD#44 decided to use scanning for a similar project at Queen Mary Elementary School. The project scope was similar to that at Ridgeway Elementary.
