Project Planning

HydroSurvey Australia provides expert and specialised consultancy services to a range of new and regular clients each year. A responsive and flexible approach ensures that we are able to meet client requirements, providing solutions designed to accommodate large and smaller projects.

All survey work undertaken is conducted in accordance with Quality Assurance Standards, with systems and procedures conforming to AS/NZS ISO 9001 certification.

Prior to each job and in consultation with the client, the survey area and degree of coverage is determined. Survey runlines are then calculated and a site plan produced.

Log sheets for each survey are kept and critical calibration settings such as draft, squat, speed of sound and elements of the position fixing equipment, such as the height of the instrument, are recorded.

A record of each runline, and events on that runline, are noted so that any ambiguity in the depth/position measurement can be correctly determined during the editing process.

Tidal datums and their references are routinely maintained and checked, with portable field tide gauges calibrated and checked against the standard gauge over the range of tide. Tide gauges are deployed as close as possible to the survey site or on either side of it to ensure reliable water levels are recorded. Visual tide board readings are also made to verify logger data.
