CTIL – Catterick Garrison, North Yorkshire, England
Client: CTIL – Catterick Garrison
Project length: 2 months
Project value: £37k
Completion date: April 2018
HF divisions involved: Comms
Brief project description: Complete site build, including civil works incorporating fencing, concrete base, electrical works and cable ducts.
Installation of a new 20m Hutchinson tower with 2No SHF 0.6M HP dishes at 18.7m and 3No Kathrein antennas, also at 18.7m, with associated MHAs, cable trays and feeders. Also included was the installation of 1No Ericsson RBS outdoor cabinet and 1No Alifabs meter cabinet.
Project Challenges: The biggest challenge faced was access into the Northern Gas site. Although an Arqiva project, the site was owned by Northern Gas. Full supervision would be required for each daily task, however Northern Gas did not have the available resources to commit to daily supervision.
After a PSM, it was agreed that if we fenced off the area with Herras fencing, we could claim this land as Arqiva’s. We could then build a permanent fence, thus ensuring supervision would not be required within the compound for the civils works and for the tower build, as per the design.
Another challenge encountered was the access track for delivery of the tower. This was frequently used as a bridle-path. Full safety barriers had to be in place, and all parties were required to recognise that works would have to stop to allow horses and their riders to pass.
Furthermore, the crane could not park on this access track.
We had to explore other options to allow a crane lift:
If we used the access track, we would need notice to block off the path
If we used the nearby field, we would need to arrange access with a third party
If we used a normal 40-ton crane, we would need matting and trackway in the compound owned by Northern Gas, which was not accepted
HF were able to get a slimmer, tracked crane to be used within the Arqiva owned compound, thus negating the requirement for trackway. Subsequently, the costs and time constraints associated with the utilisation of trackway did not apply.
The installation was completed on time and within budget
