As for us we decided we only need
I also worked on finalizing the frames and grates we will use for that one set of structures on our road project I mentioned in an earlier post. The idea is to replace the existing frames and grates with ones that better fit the structures. This will decrease the potential for failure of the pavement in the future. The sales person for EJIW did a great job picking out a frame and grate that would work. And once I verified it was what we wanted, I ordered them for the project.
Establishing Horizontal and Vertical Control Points
Around lunch time
I spoke with and inspected the work we had arranged to have done to set a permanent horizontal and vertical control point on the property at public works. The type of monument set is a Crypto Users Number Berntsen monument. This is the culmination of much research related to how benchmarks should be handled. In the “old days” we would have ran a series of benchmark circuits and set up a network of benchmarks throughout the city. With GPS, the method of handling benchmarks is evolving to a different type of network. Instead agencies are setting up a small number of control points set to first-order precision.
Then all work is performed
Using GPS units that reference back to these control points. We realize not everyone has the necessary GPS units, and our division does not yet have this equipment. But many companies do so we thought Brazil Phone Number rather than waste money setting up a system that will be obsolete by the time it is done, it’s better to spend less money setting up a more state-of-the-art system that will better support future practices. a benchmark referenced to USGS datum about once a year. So it’s cheaper to hire someone to set a localized benchmark for that one time a year. For the rest of our work, we only use a project-based datum. The photos in the post show the monument that was set.
