Early Contractor Involvement

Spencer Bridge Engineering is a recognised leader in Early Contractor Involvement (ECI) for complex bridge projects, supporting clients and consultants in achieving cost and programme certainty from the outset. Our ECI expertise has contributed to landmark structures including the Menai Suspension Bridge, Tay Road Bridge, and Millennium Bridge in London.

By providing contractor-led technical input early in the project lifecycle, we help define efficient, realistic scopes of work that reflect the true extent of necessary interventions. This proactive approach supports informed decision-making, manages public expectations, and reduces the risk of delays or unforeseen works.

Our in-house design team collaborates closely with construction professionals during ECI to develop engineering options, assess buildability, and provide accurate budget and programme data. We also consider long-term maintenance to ensure value beyond initial delivery.

ECI enables early mobilisation and knowledge transfer, avoiding delays common in traditional procurement routes. We have introduced innovative solutions—such as revised methodologies and bespoke temporary works—to improve quality and minimise environmental impact.

With over 30 years of experience in bridge construction and inspection, Spencer Bridge Engineering is well-placed to identify risks early, tailor methodologies, and provide confidence to clients, stakeholders, and the public in delivering complex infrastructure projects.
