Plex.Earth - Taking the guesswork out of Civil Design

Numerous studies estimate the average cost of rework on civil engineering projects to be higher than 5%, occasionally exceeding 15% and some report about project reworking surpassing 30%.

As a civil engineer I was the CAD manager and responsible for the design of the general layout on many sanitary landfill projects. Rework was some kind of a habit, since customers, contractors or other stakeholders were asking for changes regularly. It was just the regular routine. But one project forever changed the way I was seeing my job, and my tolerance of rework:

A construction site had been installed and the first drillings started when we realized that the terrain in the northwestern part was substantially different than what we had in mind and designed for. Not surprisingly it was a steep area covered with dense vegetation and difficult to approach. I’m pretty confident the survey we had received for that part was the result of guesswork, which meant that our work was also a product of fantasy.
