Engineering surveys play a critical role in the planning and design of infrastructure and development projects. These surveys provide accurate planimetric and topographic data, capturing both the horizontal features and vertical relief of a site. By mapping existing conditions—including buildings, utilities, drainage features, and terrain—engineering surveys give designers the reliable spatial information needed to create effective and efficient plans. Whether for roads, utilities, site grading, or stormwater management, precise survey data is essential to minimizing design errors, avoiding costly construction issues, and ensuring project success from the ground up.
