2 Degrees National Rollout – NZ Wide

Griffiths Construction became involved in the 2 Degrees National Rollout of cellphone towers towards the tail-end of Tier 1. This meant we were actively involved in everything from tower upgrades to complete construction of new towers, some of which were located in the most remote and hard to access areas. The locations, extreme weather and ground conditions constantly changed throughout this project. We believe the successful completion of this Rollout is testimony to our project management skills, professional work ethos and establishing a good relationship with all the local contractors who were used.

Tier 1 and 2 / Huawei / Sky Communications

During this project we had extremely challenging conditions to contend with. From 33 degrees one day to snow the next. Access was also a factor with 4×4 being the normal mode of transport and helicopters required on the more remote locations.

Tier 3 / Huawei / Sky Communications / Infratel / Downer

Tier 3 of the 2 Degrees roll out has seen us successfully complete 50 sites in 16 weeks located all over the country.

Project scope

Tier 1 involved the first stage of the project and incorporated the larger main centres with Tier 2 following closely behind.

Coming into the project at the tail end of Tier 1 and covering all of Tier 2 meant we were involved in construction of everything from the complete Greenfield sites (new), right through to small road side, roof top and various locations across the country. This included areas such as Palmerston North, Whanganui, Wellington, Lower Hutt, Ashburton, Mt Hutt, Dunedin and Invercargill to name a few.

Tier 3 has seen over 100 sites built throughout the country. Areas now include; Auckland, New Plymouth, Whangamata, Putaruru, Opotiki, Whakatane, Waikato, Gisborne, Wairoa, Wairarapa, Kaikoura, Hanmer Springs, Canterbury, Timaru and Oamaru.

Complicating factors and solutions

Limited access, steep terrain and isolated locations were all complicating factors to overcome. Many of the jobs required us to first put in access tracks, the use of four wheel drive vehicles, helicopters and cranes to supply materials where trucks could not be used was also necessary.

Ground conditions went from solid rock through to water logged ground. Low water tables and underground services meant the use of casing pile holes, retaining walls and in some extreme cases a close consultation with the engineer was required to find a more suitable solution, sometimes this involved a redesign of the foundations to better suit the conditions.

Extreme weather was also an issue, strong wind, rain, snow and baking hot sun meant the correct protection was key to keeping this project on track.

Working alongside local contractors with a professional approach, good communication and understanding all contributed to the project’s successful completion.
