What is an EPC One-Stop Solution?
An EPC one-stop solution refers to a single contractor or consortium that manages engineering design, procurement of major equipment and materials, construction, installation and commissioning. Clients benefit from a single point of accountability, simplified contracts and integrated schedule control.
