what we do

Topographic Surveying for Design

Preparing reliable site information

Parametrix surveyors provide high quality information on existing site conditions to support design teams. In doing so, we reduce design risks and construction costs. We use the latest equipment and technology to provide reliable documentation of existing topography, above ground structures, and utilities. All features, both manmade and natural, are documented.

Parametrix prepared a boundary and topographic survey for Ringdall Middle School, a swing school being used to house students while three other Bellevue school sites are being rebuilt. Mapping of underground utilities was important because of utility upgrades required. Title reports and King County record information was gathered for boundary and right-of-way analysis. Upon completion of the boundary and topographic survey, we prepared a boundary line adjustment to eliminate a parcel line that ran through the middle of the school.
