Built for the field. Engineered for the office.
A single source of truth connecting the design you sketch on day one to the margin you actually keep on handover. Explore the core workflows.
3D Satellite Blueprint Canvas
Stop drawing sketches on napkins or wrestling with generic design software. Search any South African address, fetch high-resolution satellite imagery, and draw project layouts in 3D scale.
- ✓ Precise dimension scaling and automatic angle-snapping
- ✓ Layers for satellite views, vector terrain, and custom overlays
- ✓ Standardized library for walls, vegetation, panels, and access
- ✓ Calibrate the drawing against a dimension you measured on site
On accuracy: scale comes from Google Maps imagery, which is good enough to lay out and quote from, but it is not a surveyed site plan. Where a dimension has to be right, measure one edge on site and calibrate the drawing to it — everything else rescales to match. Quote off the drawing; set out off your tape.
Visual GIS Integration
Renders terrain slopes and roof pitches using Google Maps API and Cesium for hyper-accurate outdoor mapping.
Automated Bill of Materials (BOM)
Drawing lines on a map is only half the battle. SiteTower's proprietary BOM engine parses your drawing elements and runs them through localized formulas to calculate real hardware and labor requirements.
- ✓ Computes timber or composite decking runs, subframe joists, and hardware counts based on drawing layout
- ✓ Estimates pool excavation volumes, concrete shell requirements, coping paving, and safety balustrades (fully SANS compliant)
- ✓ Quantifies fencing runs, plants/sod coverage, backup solar/battery strings, and pond filtration setups
| Item Category | Drawing Reference | Computed Quantity |
|---|---|---|
| Concrete Pool Shell | 8m x 4m Shell (1.5m Depth) | 12.4 m³ Concrete, 960m Rebar |
| Composite Decking | 45m² Custom Patio Area | 250m Decking Boards, 48 Joists |
| Glass Safety Balustrade | Pool Perimeter (SANS 10134) | 16m Glass Panels, 8 Spigots |
| Filtration & Heating | Pump & Solar Geyser Loop | 1x 0.75kW Pump, 4x Solar Panels |
Proposals & digital E-Signatures
Drafting quotes in Excel and converting them to PDFs is slow and prone to formatting breakages. SiteTower outputs beautiful, white-labeled client pages accessible on any device.
- ✓ Embedded 3D project previews so clients visualize what they sign for
- ✓ Legally binding digital e-signatures for secure commitment
- ✓ Client-selectable options that reprice the quote as they toggle
On-Site Change Orders & Margins
Ensure no scope additions go unbilled. When design changes occur in the field, crew leaders or project managers can log the change on-site, compute the adjusted pricing, and collect the client signature on a mobile screen.
- ✓ Instant update to the contract value and job record
- ✓ Track quoted versus actual profit margin leaks in real-time
- ✓ One signed record per change, so nothing is argued about later
