GIS, Survey & Digital Engineering for Infrastructure Projects

TANVIXA supports infrastructure and water-sector projects with GIS mapping, spatial analysis, terrain and catchment studies, survey data processing and CAD-based engineering documentation.

Service scope

Specialist engineering support for infrastructure projects

Assignments can be defined as feasibility inputs, technical work packages, documentation support, design or report reviews, or coordinated specialist services. The exact scope, deliverables, assumptions and professional responsibilities are agreed before commencement.

GIS mapping and spatial analysis

Preparation and review of project maps, spatial datasets, thematic layers, location plans and GIS outputs based on supplied data and agreed coordinate systems.

Catchment delineation and terrain modelling

DEM-based terrain analysis, watershed and drainage delineation, slope and elevation mapping and supporting spatial outputs, subject to source-data resolution and quality.

Topographic and survey data processing

Organisation, checking and processing of survey datasets, contour information, coordinate data and digital terrain inputs for engineering use.

CAD drafting and drawing support

Preparation, conversion and editing of engineering drawings and CAD deliverables using client-supplied design information and agreed drafting standards.

Infrastructure and reservoir mapping

Mapping support for project components, reservoir areas, access routes, water conductor alignments and associated infrastructure features.

Technical data visualisation

Clear presentation of engineering and spatial information through maps, layouts, schedules and digital outputs suitable for reports and project coordination.

How we work

Defined scope. Coordinated delivery. Technical review.

Work is undertaken against agreed requirements and available project information, with responsibilities and review arrangements identified for each assignment.

1
Understand the requirement

Review the project brief, available information, required outputs and target schedule.

2
Define the work package

Agree scope, assumptions, exclusions, interfaces, responsibilities and deliverables.

3
Coordinate specialists

Allocate suitable in-house resources and specialist associates for the agreed tasks.

4
Review and submit

Coordinate checks and hand over the agreed reports, schedules, drawings or review comments.

Discuss your project with TANVIXA

Share the project background, location, available information and support required. We will review the enquiry and respond on possible next steps.

Frequently asked questions

Common questions

Can TANVIXA work with client-supplied survey data?

Yes. Data formats, coordinate reference systems, accuracy, completeness and intended use are reviewed at the start of the assignment.

Does GIS mapping replace a statutory survey?

No. GIS and digital processing outputs do not replace required field surveys, certified cadastral surveys or statutory verification unless these are separately performed by appropriately authorised professionals.
