About CoEng

How it started

​

CoEng was formed in July 2022 by Nathan Spencer and Grant Bailey.

 

Nathan has been in consulting since 2000, with a specific focus on the overhead lines space since 2006. Nathan's specialty is in the structural design and asset management of poles and their foundations. He has been running consultancy offices in the space since 2011.

​​

Grant worked with Ausgrid for around 18 years before Nathan heard he was planning to leave the industry and become a high school teacher. Nathan convinced grant to try consulting and focus his passion for teaching towards the overhead line industry. Grant is an electrical engineer who specialises in overhead line design, lidar capture and management, line design training and line design software configuration and training.

Expansion

​

In December 2023 we onboarded David Clancy. David worked for Powercor from 2007 in various roles, with his most recent role leading the implimentation of AUD and Neara for use in line design and asset management. David is both electrically and structurally qualified and has extensive experience in configuration and integration of design, GIS, Accounting, and asset management data systems in the utility industry.​

​

We also have sub-contractor agreements with a number of engineers who have their own business set up but use CoEng's insurance, sign-off qualifications or existing supplier registrations to deliver their work. We have also completed a number of projects where we engage other firms, or are engaged by other firms as sub-contractors to deliver larger projects. The flexibility of this approach has delivered significant value to our clients and is a big part of our success.

​

How it's going

​

We are all enjoying life and the freedoms that working for ourselves involves. We are busy delivering projects all across Australia and New Zealand and we are keeping our eye out for people who wish to join either as employees or as specialists.

​​

We are a key partner of Neara. We subcontract to them to assist with configuration, model building, standard NZ configuration development, training and module development. We also subcontract directly to the utilities to do the same, depending on how the customer wants to structure their engagement. This has been a great relationship. We have watched Neara grow and impliment feedback to become a powerhouse in the network design and analytics space. Being a project-based contractor allows us to maintain independence and provide advice that is specific to the customer. Our experience within the industry also allows us to streamline onboarding and configuration because we can cut through a lot of the terminology differences and nuances that each utility has quicker than most.

​

On the asset management and general design side of things we have assisted a number of utilities in their assessment of and deployment of various NDT testing devices for wood poles, as well as completing a significant study on condition assessment of stay rods using NDT. We have assisted TasNetworks with a range of improvements to their construction and design manual and continue to assist various utilities across Australia and New Zealand with their pole testing and inspection documentation and training.

​

The general design side of the business has seen significant growth, particularly in relation to difficult designs and upgrading/new lines up to 220kV for datacenter developments. Our ability to think outside the box and our first-principles approach allows us to deliver cost-effective solutions for difficult lines that don't fit the usual standard constructions.

​

2025 has seen the development and release of a number of products to fill gaps in the utility industry:

  • We started working with Cloneable as the AU/NZ distributor of their inspection and data collection field mobility app. The first 6 months or so was about planning, configuring and testing to ensure we had an app that was suitable for the typical field processes in AU/NZ. 2026 and beyond is about getting it in the hands of the utilities.​

  • We released our power pole foundation design software LatPole in 2025 as a web-app in beta. This is an improved version of the one that Nathan developed for Ausgrid originally and automates the P-Y design method for poles. 2026 will see the full release, as well as the release of a plugin for Neara users so that they can design more efficient foundations without having to leave the software.

  • We developed a plugin for converting Neara models into AutoCAD drawings. This streamlines the process of converting Neara designs into documentation for construction crews and is gaining considerable interest.​​

​

So we think things are going great!

​

CoEng structure

​​

We are a "co-working" engineering consultancy. We work together, with autonomy.

​

CoEng is set up to enable specialist engineers to run their own semi-independent business units. Each specialist manages their own budgets and workflow, but does so under a framework that allows for shared:

  • Offices & associated expenses,

  • Shared personnel resources,

  • Shared insurance costs,

  • Shared accounting services,

  • Shared equipment,

  • Shared ISO accreditations, etc.

This minimises the hassles and risks of running your own consulting firm, but has the flexibility to grow your revenue streams and teams as much as you like, and provides additional security and redundancy for your clients.

It has been set up in a way that any specialist can utilise the infrastructure to provide long-term or ad-hoc services, without the hassle of everything that comes with setting up an individual business. We will even help support the smooth transition into the consulting world if new to consulting.
 

Why?

​

Over the years we have seen many experts given redundancy from large government and private organisations. Knowledge that in many cases is lost because those people don't want the hassle of being a cog in a large consulting firm, nor do they want to set up their own consulting business.

Some don't know where to start, what to charge, how to quote, etc.

Insurance and general business expenses add up very quickly, then you have all the accounting work and costs involved with admin, branding, marketing, etc.

​

The way we have set this up provides by far the easiest platform for specialist engineers to provide their services and grow a business from scratch.
