/ Delivery
Your system was designed carefully. Now it needs to be built that way.
Design and construction are two separate phases with two separate risk profiles. Every design decision, from equipment specs to cable routing to array layouts, needs to be carefully and professionally built. Installation quality has a big impact on the reliability, safety and performance of a system. Revolve works collaboratively with contractors to manage the installation quality, from the first tender through to commissioning sign-off.
How we manage your build
Procurement, construction oversight, and commissioning validation, all handled independently of the installer. Your design specification is the benchmark at every stage. It defines the requirements that procurement is built around, and the standard the build is held to. We work alongside the contractor from tender through to commissioning, ensuring what's delivered matches the design - not what was convenient or available on the day, but what will perform over the long term.
Procurement
Revolve coordinates competitive tenders with experienced and qualified installers, using your design specification to ensure every contractor is pricing the same scope. Each tender is assessed on more than price - we also consider contractor capability, team experience, proposed equipment, installation methodology, and long-term value. You receive a clear recommendation with the reasoning behind it - we take no commissions and have no preferred suppliers.
Construction QA
Independent quality assurance throughout the build. Revolve reviews contractor shop drawings and product selections before construction begins. Each site visit is documented in a written report: what was inspected, what matched spec, and what needed to be resolved before the build can progress. Equipment models, cable sizing, mounting systems, electrical connections are checked against the design at each stage. Drone technology can be used to verify equipment positions during construction and to thermographically image the completed system, identifying hidden faults that aren't visible on the ground.
Commissioning
Performance testing, system validation, and formal handover. Revolve is involved through the commissioning process - reviewing procedures, witnessing testing, and verifying results against the design intent. Before sign-off, we can independently confirm that the system is generating in line with the modelled performance. You receive complete as-built documentation and coordinated warranty information, giving you a clear record of exactly what was built and how to maintain it in the future.
/ what you get
A system that matches the design
Independent oversight from procurement through commissioning, with clear reporting at every stage. By the time the system is handed over, you will have a verified record of what was built, how it was tested, and how it performs against the design.
Competitive procurement (Multiple tenders)
Independent tender coordination across the full installer market. The process is structured so quotes are comparable and assessed against your design specification. The lowest upfront cost doesn't always result in the lowest cost of energy. Each tender is reviewed for contractor capability, team experience, proposed equipment, and installation approach. With no commissions and no preferred suppliers, the recommendation is based on what best fits your project and meets your long-term outcomes.
Independent QA reports + performance validation
Written site visit reports throughout construction, documenting what was inspected, what was found, and what was resolved before work progressed. Post-commissioning testing verifies performance testing against the design targets. The result is a clear, verified record of how the system was built and tested, and what it is delivering at handover.
As-built documentation + warranty coordination
Complete as-built records showing what was installed, where, and to what standard. The documentation includes testing results, warranty information, and a full handover package.

The gap between design and reality
Construction introduces variables the design can't fully anticipate.
At one end of the scale, the issues caught on site are often smaller: cable management, correct torquing of fasteners, labelling. Small details can cause significant problems and impact the system's reliability and performance over time.
Occasionally they are more fundamental: product substitutions, equipment faults, poor workmanship. These aren't rare edge cases. They're the normal gap between a design document and a physical build. Revolve's delivery process is specifically structured to verify the installed product at the point in the build where they can still be corrected.
The documentation produced during that process is more than a record of what happened. It proves the system was built to specification and gives you a performance baseline for its full operational life. That record is what protects the investment at year five, year ten, and year twenty-five. A well-managed delivery phase costs a fraction of the performance it secures.

/ FAQ
Common questions
How long does a typical project take to build?
A simple commercial rooftop retrofit typically takes three to 6 months from procurement through to commissioning. Larger or more complex projects, particularly new builds with solar integrated into the construction programme, can run to 12 months or more. The main variables are procurement lead times for equipment, installer availability, and grid connection approvals. It's worth noting that day-to-day programme management is typically handled by an independent project manager, not Revolve. Our role covers construction oversight and quality assurance. We'll map out a realistic programme at the start, flag risks early, and raise anything on the quality or specification side the moment it appears.
Do you do the installation yourselves?
No. We're independent consultants, not installers. Our job is to make sure whoever builds it, builds it right. We coordinate procurement, manage the tender process, oversee construction quality, and validate performance at commissioning. The installer is selected through competitive tender based on your design specification. Because we don't install, we have no reason to recommend a particular contractor.
What happens if the installer makes a mistake?
Revolve works collaboratively with installers to ensure the design is understood, set expectations of quality and answer questions as they arise. But mistakes do happen, and that is why independent QA exists. Every site visit checks what's being installed against what was specified. Often the issues are smaller than expected: cable management, correct torquing of fasteners, labelling. At other times, more significant issues arise: product substitutions, equipment faults, poor workmanship. When Revolve identifies a deviation, it's raised immediately with the installer and documented in the site report. This ensures issues caught during construction are resolved before they're locked into the system. Catching them at that stage is significantly less disruptive than addressing them later under warranty conditions.
How do you handle cost overruns?
The procurement process is structured to minimise surprises. The design specification is detailed enough that installers are quoting against clear requirements, not guessing at scope. Variations during construction are assessed independently, so you have an objective view of whether a cost increase reflects genuine site conditions or scope that was always in the design. If a cost risk emerges, you'll hear about it from Revolve early, with options, not as a fait accompli at project close.
What do we receive at handover?
A complete as-built documentation package: engineering drawings reflecting what was actually installed, performance validation results from commissioning, warranty documentation for all major components, and a full handover report. This is the evidence trail that proves your system was built to spec and is performing as designed. It's detailed enough for a board presentation and robust enough for an engineer's review. If you move into our operations phase, this documentation becomes the performance baseline we measure against for the next 25 years.
