In these situations, we work hard to get everybody on the same page. What tolerance are they held to for base? (This can cause issues with minimum depth requirements.).
We have a lot of clients that are performing paving only, weather asphalt or white paving.

Native software can easily make sense of these elements and go a long way in producing great roads when using the same brand of machine control as the software. To create a model that can be properly read by machine control starts with a road job, meaning alignments and templates. Using an older program like Terramodel and then converting that into an xml surface will cause problems that will never be worked out in the machine control’s attempts to get things right. The way a model is built plays a big part in making a road turn out smooth. When there is some latitude allowed, we can make things better. All roads need to be in specified tolerances. We are talking about precise adjustments in parameters to improve the surface. When value engineering is allowed, or the job is a design/build, we can adjust the profiles and super elevated curve sections to make machine control better. The reason I mention this is that as competent model builders we can improve the contractor’s chance of getting their IRI bonus. Different types of roads have different requirements depending on location, number of lanes and traffic count. Contractors will receive a bonus if the IRI is within tolerances specified in the contract documents.

Various methods are used to measure the index, from simpler manual units to electronic systems. A good IRI is less than 95 inches per mile while poor is over 170. IRI is useful for assessing overall pavement ride quality a higher IRI value indicates a rougher road surface. Reported in units of inches-per-mile, the IRI describes how much total vertical movement a standard passenger vehicle’s body would experience if driven over a 1-mile segment of the subject pavement at 50 mph. A continuous profile along the road is measured and analyzed to summarize qualities of pavement surface deviations that impact vehicle suspension movement.
IRI is the standard to quantify road surface roughness. I will cover some things we have been doing for years as well as some newer uses for data in a road model. This only happens because the manufacturers trust our work, guaranteeing success. Equipment manufacturers put data modelers together with these people to make things easier. A client that is new to high level machine control may not initially want to be tasked with model building in addition to field responsibilities. It is satisfying to help a contractor by providing the correct files for their new technology. Over the years we have made sure to be in front of the curve. Construction technology manufacturers know the high stakes associated with this work and focus their development on being first to market for new concepts and improvements. Even with machine control technology being used in all aspects of civil construction, highway work still benefits from being on the front lines of development.

I can remember when Blade Pro 3D and a robot could make crisp crown transitions and get contractors bonus money for smoothness. Initially, the biggest impact from machine control came to the heavy highway contractors.
