All technical inquiries receive an initial acknowledgment within 4 hours. Complex survey or drainage calculations may require up to 48 hours for a full response.
Common inquiries about geodetic surveying, topographic mapping, and rural drainage consulting.
We rely on RTK-GNSS receivers and robotic total stations for high-accuracy measurements on slopes exceeding 25 degrees. In dense vegetation or valley areas with limited satellite visibility, we supplement with terrestrial laser scanning to capture ground detail without compromising precision.
We apply Manning’s equation using field-verified slope data and catchment area analysis. Each channel cross-section is sized for a 10-year storm event, with freeboard and erosion control factored in. The output includes flow velocity, required depth, and maintenance access recommendations.
Standard deliverables are 1:500 scale maps with 0.5-meter contour intervals. For larger parcels or less complex terrain, we can adjust to 1:1000 scale with 1-meter intervals. All maps include spot elevations, vegetation boundaries, and existing drainage features.
Yes. We install monumented control points tied to the national geodetic datum using static GNSS observations. Each marker is surveyed with millimeter-level precision, and we provide adjusted coordinates along with a metadata report. This ensures consistency across multi-year land consolidation or infrastructure projects.
We combine RTK-GNSS with total station traverses and, where needed, terrestrial laser scanning. This hybrid approach maintains survey-grade accuracy even when canopy cover or terrain blocks satellite signals. All measurements are adjusted to the national datum for consistency.
You receive a full hydraulic report with channel cross-section drawings, flow velocity tables, and construction-ready plans. The report also includes maintenance access points and erosion control specifications. All data is delivered in both PDF and editable CAD formats.
