I’ve been seeing a lot of commercial projects go over budget lately, and most of the time it comes down to inaccurate planning in the early stages. Things like missing quantities, incorrect assumptions, or incomplete scope details can really mess things up later.

From my experience, having a detailed estimate before starting makes a big difference. Commercial jobs are usually more complex, so even small errors can turn into big cost issues. That’s why some contractors I know prefer working with expert commercial estimating services to get more reliable numbers from the start.

It also helps with bidding, since you’re not underpricing or overpricing the job.

How do you guys manage estimates for commercial projects? Do you handle everything in-house or bring in outside help sometimes?
