While some of the work has been hard Doug says the team was keen to go the extra mile for the project and they’ve all felt immense satisfaction.

“Pest management is a major component of the Mt Messenger project and it’s vital for the ongoing survival and reproduction of the forest itself and the organisms that live in it.”

Glenn Coppard - Design Manager

Glenn has over 20 years of professional experience with extensive skills in civil engineering design, drafting and documentation. He’s been involved in the Mt. Messenger Bypass for the last two years working alongside planning and construction teams to develop a range of options for the Multi Criteria Analysis, and the preferred route for consenting of the proposed scheme.

His commitment to consistently designing innovative engineering solutions tailored to the site has been of huge value on the project.

“Using technology is one of the most powerful tools we have and it has been really valuable on Mt Messenger. We’ve been able to use it for public engagement to create a digital representation of what it will look like. For stakeholders to be able to see what the project will look like and what effect it will have, that’s really powerful.”

Glenn carried out detailed development of the projects temporary works and construction sequencing, which has been key to understanding the effects of the project, not only on the environment, but the cost and programme implications.
