Early Contractor Involvement (ECI) is a productive technique for changing current contracts and execution models to improve cooperation between the owner, designer/consultant, and contractor. Early use of contractor knowledge to speed up a project timetable is a crucial benefit. Before design work is finished, it is possible to examine important constructability and feasibility factors and spot potential issues by involving the construction provider early on in the process. While the design is being finalized, a crucial work path can be built concurrently. The proven success-drivers in Integrated Project Delivery, Progressive Design Build, ECI P3 and Alliance include ECI and collaborative contracting. We continue to offer cutting-edge solutions to difficult construction problems thanks to Graham's extensive experience in creating and implementing collaborative contracting models like ECI. significant cost savings through solutions, quicker project
