City Rail Link Project

City Rail Link (CRL) is Auckland’s first underground rail line and the largest transport infrastructure project ever undertaken in New Zealand. Ventilation and dust control are needed to keep workers’ exposure to fumes and dust at safe, acceptable levels. Grydale provided ventilation design consulting to develop an extract ventilation system for the excavation of K-Road Station

Coastal Powder Coating

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. Coastal Powdercoating decided to invest in a facilities upgrade programme to expand their operations. A core part of the programme was a larger blast room to enable larger powder coating projects to be undertaken more efficiently in-house, without affecting the quality of the end product.

Ventilation Design Systems in Tunnelling

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. New health and safety regulations specifically relating to the control of respirable crystalline silica (RCS), have been introduced to bring it into line with asbestos.

Dust Control on Metro Tunnel Project

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.

Greenbank Sewer Rising Main Project

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.

Bulk Storage Facility

Our client has two 8000m2 sheds that store zinc and copper concentrate before being distributed to customers across the globe. Zinc and Copper dust needed to be fully contained within each shed to protect against spillage, avoid cross contamination and ensure environmental security. With the added challenge of having the port directly opposite Townsville, EHP limits placed on the client meant no visible dust was allowed to escape each building. Grydale were commissioned to design, manufacture and install a JMS 48 F-Series Dust Collection System for each storage shed (zinc and copper) to manage dust created through loading and unloading product.

Crushing Plant Dust Extraction System

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.
