A fence being constructed under the moonlight, with workers using tools and materials to build it.
J&R is our subcontractor completing the directional drilling works. Directional drilling allows ducting to be installed without the need to trench through the road. The existing 33kV overhead powerlines will be relocated into this crossing and into the underground common service trench to allow the power poles to then be removed.

A 140 tonnes crane is lifting in an 18 tonnes stormwater treatment device. The excavation hole was dug up and prepped the night before to allow enough time for the lift and backfill. Zero Limits supervisor, Darryn, in the photo supervising the lift.

Fulton Hogan crew has completed the batter between Berry’s Bridge and Matua Road after trimming it to a finished level. Topsoil was re-spread on top and then mulched to protect the topsoil.

Phase A1 – Drainage Line Installation
Phase A2 – Cable Hauling for Chorus Cable into CST
Phase A4 – Batter Reinstatement between Berry’s Bridge and Matua Road
BEFORE – The underground service ducting is also ready for Vector to pull through their 33kV cables!

AFTER – above left and right: The cables have been pulled through the ducts and the trench is back-filled.

A large crane and digger are used to install a stormwater treatment device at night on SH16.
Installing a stormwater treatment device at night on SH16.
An engineer carries out a pavement construction beam test. This test is carried out after we have compacted the ground prior to paving so we can test the strength of the base. A truck sits on the testing device which shows us how much the base flexes under the truck’s weight. When we are sure the base is sufficiently strong, paving can occur.
Certain services, like this yellow gas line, must occasionally be moved out of the way when utility services like fibre connections and power are installed beneath the surface of the road. It’s a bit like construction tetris!
This large storm water pipe has been laid along SH16 in the roadside berm and stretches eastwards 140m to terminate near Wintour Road.

Busy night works on SH16: in the foreground, the combined services trench crew are at work while in the distance the Stormwater Team are trenching across the highway to connect new pipes to the stormwater system.
Once the trench is the correct width and length for the new stormwater pipe, layers of bedding are placed in the trench and compacted to support the pipe prior to connection and back filling.
The combined services trench crew are excavating a continuous trench to lay and connect new, empty lengths of utility service ducting along the roadside. The utility service connections can then be pulled through the ducts ready to be connected to farms, houses or businesses either soon or in the future.
This is what a new combined services trench looks like inside. The ducts are laid lengthwise in a bed of fine gravel to keep them separated and level. The warning tapes for any future excavation tell us what they will contain; orange for Vector power, Green for Chorus comms and red for Vector Comms.
After the combined services trench ducting pipes are laid and secure, the trench is carefully back filled and compacted to create an even ground surface that can withstand weights like cars and trucks travelling above.

January 2024

CST: CST stands for Combined Services Trench. The trench is carefully prepared to receive multiple underground ducting pipes. These will carry services such as power to existing and future home or commercial connections.
NE Berry Bridge: In January, work to the North East of Berry Bridge included building a platform to receive the a crane to assist with the construction of the newly widened bridge infrastructure.
Phase B - Backfilling: Once aggregate has been laid, a roller is used to compress the back-filled material.
Testing the batter: In earthworks, a `batter’ is where an excavated face is cut back to a pre-determined slope to ensure stability.
