Asset Management, Integration & Handover services

CLS-Build can now offer support staff who have over 2 years of experience in delivering Handover and integration services, covering multiple projects to date of a combined value of over £50m. From refurbing taxiways, replacing Halogens/Cegelecs with LEDś on more than 500 locations in the airfield, installing the first Mototok charger unit in the airport, and replacing all the electrical cables within the airfield, CLS can assist with your project quality and handover requirements.

Our staff have forged previous great working relationships with Balfour Beatty, JACOBS, ATG Airports, HAL LTD, Levertech, and Dyer & Butler to name a few.

 CLS-Build understands that Handover services are an important element of any project size, and we also understand that quite often these tasks are often left until the latter part of the project. Here at CLS, we engage with our suppliers from the inception stage right until the completion stage and can proactively manage your handover services to ensure a far smoother process at the back end of your project.

CLS-Build will ensure that the scope of works is correctly identified, which would, in turn, help us identify what assets and documentation are required.

We can assist in development and monitoring of a Handover programme, prepared to suit project specifics, ensuring that milestones are achieved with subcontractors/contractors' deliverables. It will also enable the project team to track and highlight progress of handover completion vs the construction programme.

CLS-Build also offers ad-hoc services, assisting where projects are busy and require an extra resource. We have the experience and flexibility to get involved midway through a project and ensure your handover works are supported toward being completed on time, and to both yours and the client's expectations.
