After reaching the limits of drilling and blasting without creating excessive vibration and dust for the surrounding environment, Breendon need to find another viable solution. Rock excavation specialists AJ Gammond provided an innovative solution.

City Rail Link (CRL) is Auckland’s first underground rail line and the largest transport infrastructure project ever undertaken in New Zealand. CRL will transform the downtown Britomart Transport Centre into a two-way through-station, doubling the capacity, reducing travel times and supporting a growing population with a world-class transit system.

Sandblasting generates large volumes of dust that can be toxic and small enough to be inhaled into lungs and thus can be hazardous to workers.

A critical aspect of any tunnel construction is ventilation design and dust control, so that workers exposure to fumes and dust are reduced to safe, acceptable levels. There are many types of ventilation design and dust control systems and as each tunnel is unique so is each ventilation design and dust control solution.

The Metro Tunnel provided some unique challenges for the ventilation design, including space and noise constraints plus the location on excavation works within the CBD. The design was created using Ventsim Design 5 to simulate ventilation, airflows, pressures, heat, gases, radon, fire and other key ventilation data to be considered, along with managing the financial constraints of the project.

Green Civil rented a JMS-20-MDT from Grydale Rental to work alongside a Vermeer Trencher to manage the dust creating from completing trenching work in Sydney.

The Greenbank Sewer Rising Main project was undertaken by Diona in November 2019, for the Logan Water Infrastructure Alliance and involved the installation of 5.6 kilometres of sewer rising main pipeline. They hired a JMS-20-MDT (Diesel, Track) dust collector from Grydale Rental to manage the silica dust created as a result of trenching through sandstone.

Our clients’ site expansion works, included a tender for a dust extraction system to manage dust created by two secondary and tertiary cone crushers and three screening plants. Grydale were awarded the contract to design, manufacture and install a Grydale JMS 48 F-Series Dust Extraction System. This unit provided 38,000m3/hr of air flow at -2.0kPA, which offered the capacity to extract dust from the two secondary and tertiary cone crushers and three screening plants.
