Every rail and infrastructure project is managed through a clear process that supports safety, compliance and programme certainty in live and access-constrained environments.
Every rail and infrastructure project is managed through a clear process that supports safety, compliance and programme certainty in live and access-constrained environments.
STEP 1:
PLANNING AND PREPARATION
We begin with detailed surveys, preconstruction documentation and risk assessments and programme development, setting out activities, durations, access windows, possessions and isolations so the sequence is understood before work begins. During this preconstruction phase, we take a proactive approach - working closely with designers and stakeholders to confirm buildability, maintainability and alignment with operational requirements.
