Many contractors start out estimating and learning how to estimate using what I refer to as the "Yellow Pad Method". Using paper and a pencil they can create estimates any time and on the fly. However as the business grows, particularly when others take over the management and building of projects sold, the typical yellow pad estimate may not give the build team the information they need to build the project on their own. Also, the information within the yellow pad estimate may not be in an intuitive and organized format, making it hard to find the information they need.
I came to this realization as I built my company and eventually formalized my estimating method and started using a better tool to get it done. I learned at lot by attending training seminars, reading articles and plenty of trial and error. In this blog post I'll share a little about what I learned during the evolution in hopes it will help your estimating evolve.
I'll even offer you a free copy of my recently updated Excel Estimating Spreadsheet Template.
Actually I think yellow pad estimating is the best way to learn how to estimate. I say this because every time you do a new estimate you start out with a blank canvas. This allows you to be creative and try new ways to estimate and organize your info each time you do one. Using the yellow pad I learned how to do estimates in a variety of formats. For example the information in the estimate could be listed in critical path order, the same order I promised my client and therefore wanted my production team to build it. For another client I assembled the information room by room so they could decide what to do at a later date if the total cost came in higher than their current budget.
Using the yellow pad I could also do quick estimates for small projects on the fly. This often allowed me to sell the job at the first visit as long as I could also easily write up my proposal ready for a signature. That was back in the good old days when work was plenty and hand written proposals were the norm.
Eventually I became frustrated with many of the limitations of using the yellow pad to estimate. Here is a brief list of what I ran into that motivated me to make the switch to using Excel spreadsheets instead.
- I had to add up all the numbers with a calculator multiple times before having enough confidence to give it to my prospects because I didn't always get the same number!
- Cutting and pasting to insert missed tasks was literally cutting and pasting using scissors and tape.
- If a prospect who several months back had said no to my price called back to go ahead, making updates to the estimate was not possible, I had to do it all over again.
- If the customer wanted to make product substitutions or wanted suggestions to value engineer the project, to be confident about the price differences I had to do the estimate all over again for each option.
- After hand writing the estimate and proposal me or my staff then had to also hand write out the sub contractor agreements and the materials lists.
- When I had to do another estimate for a similar project trying to reuse an old estimate wasn't as simple as copying and pasting or changing the quantities like it could be using a computer to do so.
Then I started using Excel to Estimate
Eventually, after a lot of experimenting using the yellow pad I eventually incorporated what I had learned into an Excel Estimating spreadsheet I created on my own. Doing so definitely improved the speed and accuracy of my estimating methods. The end result also provided the majority of information the production team needed so they could build the job without me around, leaving me time to sell more work.
