Griffiths Civil Build Projects

Repiling, Decking & House Repairs - Grafton Rd

This project involved carrying out repairs to an existing home on Grafton Road in Roseneath. All the work had been identified during a pre-purchase building inspection and subsequent engineers report. The home was down 113 steps, which added the challenge of everything being carried by hand to and from the worksite.     

Below is a list of all the work Griffiths Civil Build completed on this project:

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.

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.

Telecom NZ Site Builds - North Island

Cell phone tower construction throughout the North Island. The ‘roadside' project in Palmerston North required an onsite traffic management policy, the construction at Avalon needed specialist environmental precautions and Otaki was the first to utilise Telecom's own specific design.

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.
