Topographic & As-Built Mapping

Topographic mapping is often the first step in the design process, providing architects, civil engineers, geotechnical engineers, planners, and contractors with maps that delineate the existing-conditions data needed to evaluate feasibility, access, drainage, compliance, design concepts, and constructability.

Topographic and as-built surveys document the true existing conditions of a site — both the natural landform and the built improvements. These maps typically include contour lines, spot elevations, natural terrain features, and improvements such as structures, walls, pavement, surface utilities, fences, and portions of adjacent properties.

As-built mapping is used to record the final horizontal and vertical location of improvements constructed in the field. This may occur at project completion, or at interim milestones for regulatory reviews, design drawings, or governmental submittals.

At CA5, we collect precise field data using GPS, robotic total stations, 3D laser scanning, and/or drone-based photogrammetry — depending on site needs, scale, and terrain. The result is a highly accurate representation of current site conditions that becomes the foundation for planning, design, entitlement, engineering, and construction documentation.
