Codford, Warminster with projects across the UK

Contracting

Full time

Permanent

Five Rivers are a widely recognised industry specialist in the consultation, design and delivery of ecological, environmental and civil engineering solutions. With over 25 years of working with nature, the business continues to experience sustained growth, driven by a strong customer focus, technical excellence and an ability to attract, develop and retain exceptional people.

We are looking for an experienced Site Manager to join our contracting team, delivering a diverse portfolio of civils and environmental projects across the UK. This is a hands‑on leadership role, focused on ensuring projects are delivered safely, to the required quality, on programme and within commercial targets (SQTC).

This is a full‑time, on‑site role involving regular travel and periods of staying away from home, unless the site is within a commutable distance, which cannot be guaranteed.

As Site Manager, you will take full responsibility for the on‑site management and coordination of civils and environmental schemes, from pre‑construction through to completion and close‑out. You will lead site teams, manage subcontractors and suppliers and work closely with Project Managers and the wider business to ensure successful delivery.

With Safety and Quality as a given, the role places particular emphasis on time management, programme control and commercial awareness, understanding how site performance impacts project and business unit outcomes.

You will be involved in the practical delivery of both built and nature‑based solutions, working in environmentally sensitive locations and contributing to projects that promote biodiversity, ecosystem services and climate resilience.
