Griffiths Civil Build Projects

Telecom NZ Site Builds - North Island

Griffiths Civil Build has recently completed the construction of a number of cell phone towers for Telecom New Zealand. These sites were located all over the North Island, such as Avalon, Otaki and 'roadside' projects in Palmerston North. 


Project scope

While Palmerston North required an onsite traffic management policy and the construction at Avalon had to undertake special environmental precautions to ensure the pristine conditions of the surrounding golf course were maintained, we considered all the projects routine civil construction and assembly work except the project at Otaki.


Complicating factors and solutions at Telecom NZ Otaki site

There were a number of factors that made this project practically challenging.

This was the first cell phone tower construction utilising Telecom's own specific design. As you can see by the photos, both the cell phone mast and the cabinet and its foundation are non-standard design.

This work highlighted the flexibility that Griffiths Civil brings to every project. We were able to adapt while working onsite, this ensured the quality of the completed construction was to the exacting detail of the Telecom plans. We were also in constant communication with the consulting engineers during every phase to minimise any unnecessary downtime and avoid potential complications.

This design required a host of steel fabrication, including the large Telecom shelter and the web-forged stairs for access. The structural steel work also had to be included into the shelters foundations due to its size.

Projects

This section shows examples of some of the most recent and key projects that Griffiths Civil Build have been involved in. It showcases the variety of work that we are capable of and gives details of the individual projects, along with a scope and other relevant details and images.

Repiling, Decking & House Repairs - Grafton Rd

This project involved carrying out repairs to an existing dwelling in Roseneath that had restricted access. Our role was to undertake repair work as identified during a pre-purchase building inspection and engineers report.

Concrete Retaining Wall & Access Road - Homebush Road

This project on Homebush Road in Wellington involved the construction of a substantial precast concrete retaining wall and other works to create an access road for a new multi-lot residential development.

Timber Retaining Wall - Home in Roseneath

This home had an old concrete retaining wall that had failed and was falling over in places. After repairing a broken pipe (causing the soil to become saturated and contributing to the old wall failing) we constructed a new timber retaining wall.

Decks & Verandahs - Aotea College, Porirua

To keep the new music block build on track, Naylor Love Construction approached us to assist with the build. This project included securing foundations for relocated buildings, constructing large deck, access ramps and framing.

Earthquake Strengthening - Royal NZ Police College

A major project and the first of its kind in New Zealand. It was particularly challenging and had to be completed outside of usual office hours so the College could remain open. Limited space, harder than expected rock and ground water had to be overcome to successfully complete the job.

Retaining Walls - Commercial Projects

Griffiths Civil Build have a comprehensive background of successfully completing a wide range of retaining walls. See examples of our work that include an RBI upgrade for Vodafone, a new retaining wall on Paekakariki Hill Road and work in the city for Victoria University,

2 Degrees National Rollout - NZ Wide

Details of the national rollout for 2 Degrees. Tier 1 covered work in all the major centres, Tier 2 involved more remote locations that required helicopter and 4X4 access, while Tier 3 saw the completion of over 100 cell tower sites all over the country.

West Wind Farm

Limited access, steep terrain, wet slippery conditions and very high winds were complicating factors. Also the rock was very fractured due to the proximity of the main fault line.

Transpower Tower Foundation Strengthening

This project involved upgrading the foundations on transmission line towers in the upper South Island. We are proud to be associated with the 2007 New Zealand Engineering Excellence Awards Supreme Award winner.

Soil Nail Wall - Dowse to Petone

Construction of a retaining wall that included drilling and testing a sacrificial nail for design purposes, drilling and installing production nails, fabrication of nail heads, fixing mesh to the face and applying sprayed concrete.
