Win More Tenders with
Structural Certainty
Eliminate material waste, skip the quoting queue, and optimize your designs with site-specific engineering.
The "Uncertainty Tax" on Your Budget
When engineering data is missing, safety factors increase. This doesn't make the building safer—it just makes your quote more expensive.
- ❌ Conservative Assumptions: Leads to large "exclusion zones" and lost kW capacity.
- ❌ Material Waste: Closer rail spacing and excessive brackets to compensate for unknown purlin health.
- ❌ Slow Quotes: Waiting days for custom engineering fees before you can tender.
- ✅ Site-Specific Data: We inspect the roof to unlock hidden capacity and maximize solar footprint.
- ✅ Optimized Design: Proven strength allows for leaner designs, saving you steel and labor.
- ✅ Instant Pricing: Per-kW pricing model means you know your engineering costs immediately.
Comprehensive Certification Services
Roof Area Inspections
A comprehensive two-step process involving a Pre-Inspection Checklist followed by an on-site visit by a Gamcorp Inspector to gather critical building structure details.
Structural Assessment
Detailed structural analysis to determine if the existing roof structure is adequate to support the additional loads imposed by your proposed PV Array installation.
Frame Certification
Site Specific PV Array Frame Certification ensuring framing, panels, and fixings are suitable for the location. We determine optimal fixing spacing and load specifications.
Pallet Loading
Safety first. We determine the maximum pallet weight that can be placed on specific areas of the roof during the installation process to prevent damage.
Design Compliance
We issue Design Compliance Certificates required by Australian State & Territory Regulations and the NZBC. Essential for Building Certifiers and insurance purposes.
Seismic Assessment
Confirmation that seismic loads will not compromise the PV Array or its fixings to the building structure, ensuring long-term safety and stability.
