ORD Earthworks volumes

Hi,

I am looking for a method to calculate more complex cut/fill volumes with Openroads Designer update 2. This could be easily done with EAV methods, now it seems more cumbersome as EAV tools are not included in the software package anymore. I am aware that EAV is not 100% accurate method and this prismoidal approach may be eventually beneficial, however it needs a few enhancements. 

With ORD it is quite easy to create  meshes of cut and fill for simple earth work scenario when you just need to calculate  volumes between bottom of proposed road and a top of existing terrain but this is not a real life scenario at all.

In real projects we need to include at least topsoil stripping or existing pavement demolition. Adding demolition or stripping components to corridor definition is not an option for complex project where more than a few template drops are defined (there is a youtube video showing how to create topsoil stripping component posted to CivilTSG channel) - my workaround is to edit existing terrain model - actually as they will do during the construction phase - I just remove topsoil, existing pavement, etc. Time consuming but doable and in fact gives understanding of construction process. That's for typical projects.

For more complex scenarios we need to include top soils stripping, demolitions, ground replacemnet (MDC removal and replacing). Unsuitable ground should be replaced with fill when needed, etc. That was easily achievable with Inroads 8.7 - V8i SS4 when using EAV methods. How to deal with this now? What is the suggested Bentley's best practice that would work for industry standards?

thanks in advance for your thoughts.

  • Hey, I will appreciate if someone at Bentley could share their thoughts on volume calculations. If we want to use ORD in real life projects we need to be able to calculate volumes for more complex scenarios than just cut/fill between bottom mesh and existing terrain model. 

    Without such capability we will fail on the first pilot project executed with ORD.

    could you advice what is in the development pipeline for volumes calculations? Any plans for EAV resurrection or what is more preferable enhancement to new ORD volume calculation workflows?

    We are going toward pilot project in ORD, but to get a green light, I need to be sure I can complete project along with a bill of quantities. Otherwise we will fail.

    thanks for understanding,

    Adam

  • End area volumes are still necessary, even if the modelling has "advanced" beyond that.
    We are required to turn in earthwork calculations with our submittals, and those earthwork calcs must be by EAV. That's not going to change just because the software designers make some decisions.

  • Couldn't agree more Mary. We have been having meetings discussing this exact thing. EAV are not going away soon and with Bentley not giving users the tools to do them, they continue to shoot themselves in the foot. Anyone from Bentley going to weigh in?
