Most paving jobs and commercial driveways run into problems before the contractors arrive to start their work. That is because of the contractor’s haste to finish the bid, contractor’s effort to get the proposal, or because they do not know any better, make decisions that can affect the work itself, as well as the profit on the job. In this article, we will take a look at the essential elements that professionals need to review, to make sure that they are doing a better job and get a good profit.
Finding the best New York parking lot paving contractor is one of the hardest parts of the project. If you do not know anything about this subject, there is a big chance that you will have a hard time completing this job.
Using a tape measure and a measuring wheel, you have to confirm all the figures on the blueprint. You need to measure from edge to edge of the structure. You also have to identify the distance and location between structures like sewer caps, light poles and islands. The value will form the basis of your planning and bidding.
Determine the area where you will start the paving
As you will see, it is closely related to other planning problems, but you have to know where you start the paving and what direction the concrete will go. Other components usually dictate it, but in early stages, bring in the professionals who will be running the rollers, the screeds or the pavers, into the planning stage.
Know the number of passes, as well as the paving widths
It is called lining out the project. Are you going for a 10, 12 or 18-feet passes with paver? At some point, it is determined by the paver that you are using, but it is more efficient and effective to know it based on the measurement that you took and the layout.

Once you have received the initial measurement, you might find out that the first passes need to be 10 feet wide, will the next one needs to be more extensive. You might also need to pave on a different direction at first, to get the right width and number of the passes. Once you have decided the passes will be located, mark each of the a with a marker or spray paint.
Know the size of the paver that you will be using on this project
If you have different pavers to choose from, you need to make sure that you use the right size when doing the project. Choosing an 8-feet paver that extends up to 15 feet and 10 feet that can extend up to 10-feet will dramatically alter some of the decisions that you will make.
Also, it is very important to make sure that the quality of the job is always high when deciding what size to use. You do not want to extend the pavers too wide because you need to work within your screed’s limitation so you will have control on the materials.
If you are going to pave a 30-foot wide area, it is better to use a 10-feet instead of using a 15-feet. Not only that, you need to know whether you will use a paver with rubber tires or not. If you find out that the sub-grade is soft, it is better not to use paver with rubber tires.

Know the yield for every pass
Once you find out how the pass will be made, you can now start determining the mix ratio that you will need for the job. Begin the process by knowing the materials that will be used for each pass. For example, a 10-feet pass might go for 100 feet, and at 2-inches thick mat, you can figure out precisely the amount of yield needed for the pass.
By adding your total yield for all the passes, you can estimate the total weight of the job accurately. Knowing the weight of every pass and the total weight of the job also gives you a way to measure the progress of the job. If the parking lot calls for 50 to 100 tons of mixture and after three good passes, you have placed twenty tons, you know you are almost halfway done with the project and you know how much mix will be needed.
