AI Won't Replace Estimators, Quantity Surveyors or Commercial managers… But It Will Change How We Work

Over the past year, I've found myself using AI more and more in my day-to-day work. Whether it's helping structure a report, cost modelling, analysing documents, or speeding up research, it's become another tool in the toolbox.

The key word there is tool. There's been a lot of discussion about whether AI will replace the commercial roles within construction. Personally, I don't think that's the right question. The question I’ve been asking myself, is how can AI help me become a better commercial professional and allow me to add more value to my clients.

Here’s my take:

AI Gives You Time Back

AI is becoming incredibly good at supporting repetitive tasks such as reviewing specifications, comparing documents, summarising meetings and drafting reports. It doesn't replace professional judgement, it simply gives you more time to apply it.

Costing Is About More Than Numbers

An estimate isn't just a collection of rates. It's understanding risk, the programme, the client, the team, the site and the supply chain. AI can't replace experience or commercial judgement, but it can help estimators spend more time estimating and less time searching through paperwork.

Better Data Creates Better Estimates

The contractors who will benefit most from AI are those with good internal commercial data. Libraries of rates, labour outputs, procurement history and project cost records become far more valuable when AI can help analyse them quickly. Shameless plug, but this is where I am doing a lot of work with clients and enhancing their internal liabaries for quicker and more accurate estimates.

Professional Judgement Matters More

AI doesn't know your project, your client or the conversations that happened on site this morning. Those decisions still rely on experienced commercial professionals. AI supports decision-making it shouldn't replace it. Professionals should always validate the outputs of AI, there are hallucinations.

The Skills That Will Matter Most

Understanding the implications and administration of contracts, negotiating, managing risk, and communicating with people will remain essential, as will professional judgement. Strategic thinking will become even more valuable. Being able to see the bigger picture, understand the commercial implications of decisions, and provide advice that goes beyond the numbers.

My takeaway

I expect I will see more contractors taking on repetitive day-to-day administrative tasks using AI. I personally see this as a good thing, anything that can free up time in a business is an opportunity, even better If I can help that contractor make the changes to ready up for more efficient working. My role, I think, will play as a more strategic partner to businesses and help them piece together the gaps, risks, opportunities and ensure the right commercial strategy is in place along with judgement and challenge when things don’t look quite right.
