Completing infrastructure projects on budget is a complete anomaly in the UK. It simply doesn’t happen. There are always delays and cost over runs – partly because of the delays and partly because there are just so many factors that impact the costs over time.

Despite this, main contractors have the challenging task of submitting bids to tender, even though some of these projects may only start years later and run on for more than a decade. To say that estimating is a complex and difficult task is an understatement. Still, it’s an essential part of the bidding process enabling main contractors to secure a pipeline of projects.

Senior estimators are in demand because there are few with the skills to get the job right. There’s also a great deal of pressure on them to do so, which is perhaps why there aren’t many newcomers willing to take on the role. Get estimates horribly wrong and projects can fail to deliver or cost main contractors more than they earn from it. However, for those with a minimum of five years infrastructure experience, looking for career advancement, it may be the ideal opportunity.

Estimators are an integral part of bidding teams, and are people able to take in a broad view of the project as well as drill down into the details. It’s an opportunity to expand commercial understanding and learn how to link economic and political and even climate factors to project costs. Supply and demand, trade tariffs, and new environmental legislation can all impact material costs and project progress.

Climate events are another consideration, impacting changes in materials required. Recent heatwaves have seen railways in the UK buckling due to the extreme heat. Softer alloys have been adequate in the past – but not for the future. And these harder alloys will be more expensive – another cost consideration that needs to be factored in.

There are few roles that can challenge and equip you for career progression as well as being an estimator. The industry knowledge you’ll acquire and the relationships you’ll build can be invaluable. Dealing with various stakeholders, from suppliers to government departments can help you build a broad industry network. Plus building a reputation as an estimator gives you an opportunity to pass on your knowledge to the next generation entering the field.

The industry needs professionals willing to develop their skills as estimators, are you up for the challenge? It could be the most rewarding move you make.
