Topographic Survey at a Water Treatment Plant in Port Dover, Norfolk County

What was needed

The plant site had been modified during construction, and existing conditions had changed. The client needed an up-to-date topographic survey of the agreed area on the plant site, with elevations sufficient to support a revised site grading plan, improvements to site drainage, and construction of a new access driveway.

The surveying work we carried out

• Attended the site to carry out a topographic survey of the agreed area
• Recorded ground elevations, break lines, curb lines, drainage features, existing structures and visible utilities
• Tied the survey to the existing site benchmark
• Prepared a topographic plan with ground elevations and contours

Site conditions

The water treatment plant was in a construction phase. Earlier site modifications had changed the topography, and the survey was needed to record current conditions on the agreed area of the plant site.

Methods and equipment

The fieldwork was carried out using GNSS and total station methods. The survey was tied to the existing site benchmark.

Deliverables

• A topographic plan in PDF, delivered in August 2025
• A CAD file of the same plan, delivered in September 2025

How a topographic plan is used

A topographic plan gives designers a measured record of existing grades and features, so drainage and grading decisions, and the layout of a new access driveway, can be based on current site conditions.
