Stick Estimating One of the biggest time-wasters is estimating by the old stick estimating method. For those new to the business, stick estimates involve a number of steps: List all the various parts of the job. List all the hours that it will take someone to complete each portion. List all the materials that will be used on each part of the job. List each sub-contractor that you will need.
List all the other items you will have to download or rent to get the job completed, such as permits, rentals, port-a-potties, etc.
Go back through your lists and put a cost on each item.
The Best Construction Estimating Software of 2019
Last, have a knowledgeable second party double-check your lists and your math this step is the one few estimators bother to do. These steps, properly followed, will result in an accurate job cost. Apply your markup, and you have a price.
Unfortunately, because it is so time consuming, it is seldom done with care and the result is often a sales price that is inadequate to cover the cost of the job let alone the overhead and any profit required by the company. Another major flaw with stick estimating is that it requires separate material and labor takeoffs lists before you can do the math.
In reality, you don't need a material takeoff until you sell the job. Compiling one before you write a contract is a waste of time. Unit Cost Estimating Estimating should be done by unit cost only. It is much faster as much as two times than stick estimating, just as accurate, and gets you back in front of the customer sooner. You can't take three or four weeks with your quotation.
You need to be back in front of your customers with a quote in days, at most days. Unit costing follows the following steps: Compile all the line items assemblies for that job. Attach a unit cost to each line item assembly.
Total your numbers and have them checked by a second party that knows what they are doing. Then get back to your customer with your quotation and move on with the sale. Estimating Books There are a number of estimating books available with unit prices.
Care must be taken, because many of these books are regional in nature although they may claim they work everywhere. Their method of constructing a given project may be entirely different than the way you build your jobs. An example is the use of steel I-beams in the eastern United States. In the west we use glu-lam wood beams.
Pricing in many of the books is local, maybe regional. Several companies that publish estimating books will send a "modification factor" quarterly to correct their prices for your local area. Look at their book, count the number of items in the book, and multiply that by the number of towns in the United States. Tell me, how many people making phone calls to suppliers and subcontractors are needed to gather all those prices every quarter to keep everyone's price book up to date? In my opinion, you are getting the publisher's best guess on many of the prices.
That's not a great way to cost your construction project. If you decide to use one of these books, here is a quick trick to keep your book accurate for your area.
When a job is complete, take the invoices and time accumulations from that job and compare them to the prices in your book. If the book price is higher, keep it. Provides clear descriptions on what is included in the job being estimated so you know exactly what the job and the prices for that job entail.
Every cost is carefully described. It even provides suggested crew sizes, and equipment rates. Details at the link.
