Providing Solutions From Start To finish

Our Project Manager had ultimate responsibility for the coordination of construction activities, all of which were detailed within our Construction Phase Plan and associated documentation. We also produced CDM Layout Drawings, created a Site Health & Safety file, and implemented a Sensible Monitoring Plan for audits and inspections. Prior to the start of the works, our Project Manager was responsible for chairing a HAZCON meeting to ensure all hazards had been identified and planned for. We also ensured all Permits to Work were in place, which was applicable to the works being carried out. For this project, we worked to Cadent Gas’ permitry in such areas as, General Works including Site Mobilisation, Deep Excavations, and Lifting Operations. 

 PPV Group also worked closely with Cadent Gas Operatives during the mechanical works and Non-Routine Operations. This involved site inductions, briefings, supplying suitable tested plant and equipment, radios to coordinate the works running simultaneously in two locations, lifting operations, and supply emergency and rescue equipment (gantries and harnesses).
