ECI, Feasibility & Design

Early Contractor Involvement (ECI) plays a vital role in our project delivery process at Spencer Rail Engineering. By engaging with clients at the earliest possible opportunity, we are able to help shape technical development from the outset, avoiding project delays or cancellations, which can be costly for all parties.

This approach typically includes the development of options, the preparation of initial engineering proposals, and the provision of budget and programme support. Together, these elements give clients greater cost certainty while ensuring constructability, safety, and long-term maintenance considerations are embedded from the outset.

Through our in-house design team, we achieve stronger outcomes by directly integrating design with construction and procurement. This approach enables early feasibility and constructability assessment, allowing risks and opportunities to be identified and resolved during the design phase while ensuring solutions are practical and deliverable from the initial concept.

Pre-construction
Completion

Our ECI process is further strengthened by our use of Building Information Modelling (BIM), enhancing coordination, enabling proactive clash detection, and providing deeper insight into feasibility, cost, and programme. Our digital models extend beyond traditional drawings, integrating material data, sequencing, and cost intelligence to deliver true 4D and 5D visibility. This integrated approach supports safer delivery, reduces risk, and improves certainty from design through to handover.

Incorporating these principles into our project delivery process provides clients with a transparent view of costs, timescales, and risk, supporting informed long-term decision-making. Following completion of the ECI phase, clients may either procure the works through a traditional tender process or transition directly into delivery under a contract aligned with the defined scope.
