The Process

This post gives a general overview of the process of getting your concrete or asphalt work done with O'Brien Paving Inc.

Initial Contact

  1. The first step is to give us a call or click over to our Contact Us form and leave your info including your name, address, and phone number, as well as some details about what you are looking for and when you might be available to meet.
  2. If you emailed us or had to leave a message (sorry) we will get back to you as soon as we can to arrange a time for your estimate and possibly get any details we may need.
  3. You will get entered in to the schedule with one of our very knowledgeable estimators, all of which have had decades of experience in the industry. (while we generally prefer to meet with our potential client on-site so we can explain all the details and ensure they are getting exactly what they would like, in some cases we can provide an online quote, or a quote on-site without the need for the client to be there)


  1. Generally our estimate times are approximate, we really do try our best to get to each estimate at the start of the time slot, but due to the nature of the job we can't always get there on the dot. We ask for an hour window in order to give us some leeway. In some cases we may even get their early, things can get pretty unpredictable on the road, please understand, if we are a little later as well.

There are many standards for thickness depending on what the expected use of the paved surface is.

Asphalt Thickness Measurement

The thickness of the asphalt can either be stated as pre-comapction or post-compaction, it can be hard to know which is being used on a quote. Most engineering plans will call for a specified post-compaction thickness, if the contract is written to provide work based on an engineered specification then most likey the quoted thicknesses will be in post-compaction to match the specifications provided. However, more often than not when a specification is not provided, the contractor will provide the quote in pre-compaction thicknesses, this is done for a variety of reasons:
