"Project Genoa involved the supply of Microsemi synchronisation equipment and performing site surveys and subsequent installation & commissioning of seven sites in North America covering New York, New Jersey, Washington, Miami, Los Angeles and San Francisco.

During Project Genoa, Chronos was always ready to meet the challenge of our design changes. Pre-project planning in advance of the site surveys and the resultant installation method statements showed the professionalism and attention to detail that I have come to expect from Chronos.

As indicated above the installations where not without problems and therefore design changes. Chronos had to liaise with local contractors to ensure that equipment was delivered on time at the correct delivery addresses as kit was going to old closed American sites. They also had to negotiate with local contractors as to when and where the GPS cable could be installed. On some of these sites the GPS cable run was in excess of 180 metres in length over 30 stories. These GPS cable runs had diversified feeds for security and resiliency, which added to the complications of the installations. Chronos demonstrated their flexibility and experience in overcoming the issues presented to them in a timely manner.

Chronos Project Manager John Lyons was contactable at any time of the day or night to answer questions and resolve any problems which was important due to the time differences between the UK and West Coast America.

The quality of the installation exceeded expectations as did the documentation pack that was delivered at the end of the project detailing all the equipment delivered, installation method statements and commissioning data and photographs. This enabled us to hand off the sync network to our Americas Operations and to support the system moving forward."
