YOUR SITE. YOUR DATA. YOUR DECISIONS.

BUILT FOR CIVIL CONSTRUCTION, EARTHMOVING & MINING INDUSTRIES

SITECH NZ brings Propeller drone software to civil contractors, earthmoving operators, and heavy machinery businesses across New Zealand. Powered by Trimble Stratus, Propeller helps your team quote accurately, survey on demand, and stay aligned from office to site — without the overhead of traditional survey methods.

HOW IT WORKS

Getting started is straightforward:

  1. Set out ground control points across your site
  2. Fly your drone over the area you want to capture
  3. Upload your ground control data to the platform
  4. Upload your drone imagery (takes around 30 minutes)
  5. Propeller processes your dataset automatically
  6. View, analyse, and share your site maps and 3D models

FEATURES & BENEFITS

Confidently Plan and Estimate

Know Your Numbers Before You Start

  • Carry out your own site surveys ahead of tendering and throughout the job — so every quote reflects actual ground conditions, not assumptions.
  • Record detailed drone imagery of site boundaries and environmentally sensitive zones to demonstrate you’re meeting regulatory obligations.
  • Take volume measurements as often as your project demands, giving you tighter control over planning and budget.
Survey Frequently and Faster

Fresh Survey Data, Whenever You Need It

  • Pull current topographic surveys on demand — your drone does the work, no external survey crew needed.
  • Use an intuitive web-based platform to get the answers you need yourself, without delays or third-party bottlenecks.
  • Deploy your drone into steep, unstable, or otherwise hazardous areas that aren’t safe for people to enter.
Site Volumes

Accurate Volume Tracking Across Your Entire Site

  • Quantify material moved in or out of pits, stockpiles, cells, and drainage channels with confidence.
  • Run stockpile volume checks as frequently as your operation requires — safely, without sending people into the pit.
Communicate Effectively

One Source of Truth for Your Whole Team

  • Publish progress updates to a shared cloud workspace so your team, subcontractors, and clients are always working from the same information.
  • Build a clear, timestamped record of site changes — making it straightforward to resolve disputes and avoid costly rework.
  • Manage multiple sites more efficiently by handling progress checks and inspections remotely, without the need to be on the ground every time.
Design Checks

Compare What Was Designed Against What Was Built

  • Bring your design surfaces into Propeller and overlay them against your drone data to see exactly where you’re on track — and where you’re not.
  • Identify what work remains and generate clear records of what’s already been completed.
  • Check volumes, cross-sections, and slope values against your final design specifications at any point during construction.
Mobile Mapping

Field-Ready with the Trimble Stratus Mobile App

  • Extend Trimble Stratus to the field — create and share simple, interactive site maps between your office and on-site crews in real time.
  • Equip your field teams with 2D and 3D site models, live position tracking against design data, and the ability to collaborate and measure directly on screen.
  • Take geotagged photos on your phone, then pin, sort, and mark them up on the map — building a location-linked visual record as you go.
