Performance you can measure at handover.
Engineering, procurement and construction under one lump-sum contract, with output guarantees proven in witnessed tests before the facility is yours.
What is at stake.
The meter is the measure
Plants are judged in megawatts, gallons or throughput, not square feet. The contract should hold the builder to the output you financed.
Risk lives at the interfaces
Process and power projects stumble where engineering, vendors and field crews meet. One EPC contractor owns every handoff.
Financing needs fixed terms
Lenders look for a fixed price, a firm completion date and guarantees backed by damages. Lump-sum turnkey delivery provides all three.
How we deliver it.
- 01
Front-end engineering before price
We advance engineering far enough to fix the process design, major equipment and site layout before committing to a lump sum.
- 02
Equipment bought to the critical path
Transformers, switchgear, inverters, pumps and modules are ordered early, expedited and factory tested so they arrive ready.
- 03
Built and turned over by system
Field work is planned by system rather than by area, so each one can be checked and started up the moment it is complete.
- 04
Mechanical completion with no loose ends
Every system is walked down, punch-listed and signed off before commissioning begins, with nothing hidden in the handover.
- 05
Start-up and performance testing
We energize, start up and run the facility, then prove guaranteed output, efficiency and availability in tests you witness.
What lands on your desk.
Scope is set project by project. These are the working documents you can count on, updated on a regular cycle and yours to keep.
One number covering engineering, equipment, construction, commissioning and testing.
Guaranteed capacity, efficiency and availability, backed by damages in the contract.
Process, civil, structural, electrical and controls design, issued for construction and updated to as-built.
Checklists, test records and punch lists for every system, signed at mechanical completion.
Witnessed results against each guarantee, the basis for final acceptance.
Sunlight stored for after sunset.
Solar arrays were paired with a battery yard that stores the afternoon peak and sends it back to the grid after dark. As a lump-sum EPC contract, the arrays, battery yard and grid connection were engineered, bought and built as one system, then started up and tested system by system before turnover.

What owners want to know.
What does lump-sum turnkey mean in practice?
One fixed price and one completion date for a working facility. Quantity growth, vendor coordination and field productivity risk sit with us.
How are guarantees tested?
Through performance tests defined in the contract, run under agreed conditions and witnessed by you and your engineer. If the facility falls short, we fix it or pay the agreed damages.
How is mechanical completion different from substantial completion?
Mechanical completion means a system is built, tested and ready to start. Substantial completion follows commissioning and passing performance tests, when the facility is ready to operate.
Do you use EPC outside energy?
Yes. Wherever results are measured in performance, including water and wastewater treatment, substations and industrial process facilities.
Bring us the schedule that worries you.
Share the drawings, the budget or the date you cannot miss. A GilbertLanham project lead will walk through the critical path with you and tell you plainly where the risk sits.
