Over the last few weeks, we have been working on the connection for a new 450OD rising main in Bowen St, Wellington CBD on behalf of @wellingtonwater. The connection is approximately 6m deep from a new 2.55m diameter shaft into Wellington’s main intercepting sewer – a hand tunneled structure from the 1930’s.

Our team put in a couple of big shifts at the weekend on the Jervois Quay Stormwater Repair alongside E Carson & Sons, EN Ramsbottom, ATMS and a heap of other Wellington Contractors.

A very productive couple of weeks on our Featherston, Whitmore & Bowen St Rising Main Upgrade project has seen us ram a pipe 50m across Lambton Quay. Amazing to think that a critical piece of this project has now been installed underneath the ground without digging any holes in this busy intersection

Never judge a job by what we leave on the surface.

This looks like a nice section of asphalt reinstatement and some kerbing. It's hard to believe that we just completed installation of two 6m deep chambers in this busy urban Wellington street.

This week we successfully completed a 630OD Pipe Burst on Wallace St on behalf of Brian Perry Civil & Wellington Water as part of an Beca designed project.

The sun shone as we broke ground on the Featherston, Whitmore & Bowen St Rising Main Upgrade yesterday.We have been working hard on this one since early 2019 and were really excited to see it start on site.

How do you dig a 6m deep hole in a busy Wellington CBD intersection where congested underground services mean that there is very little available space in the ground?

The mighty Grundoram Koloss at work ramming a 1065OD steel casing under Willis St in Wellington's CBD. This is our largest diameter pipe ram to date and was well within the capability of the tool.

Urgent Response: On the night of Wednesday 23rd January a rain event caused an existing brick culvert to blow out under a property in Moir St. The culvert was a 640mm dia. brick structure pre-dating the property that was constructed in 1892. An amazing piece of engineering that is at the end of it’s life.

A great week here at GPFL as we completed our pipe bursting programme on Wallace St. 430m of online renewals completed by pipe bursting the existing 150 Cast Iron main with a new 180OD PE100 SDR11 pipe.

There is more to the Wallace St Pipeline Corridor than just a big bulk watermain. The project includes renewals of Stormwater, Wastewater and Potable Water reticulation networks across Mt Cook.

Progress is good on the Porirua Branch Extension project that we are undertaking on behalf of Wellington Water. This project will provide resilience and cater for growth in Eastern Porirua.
