    From ProSteel to BIM. TEKLA or Advance Steel?

    What can't you do with ProSteel that you want Tekla or SDS/2 to do? I'm interested in this in particular for bridge elements. Anyway, ProSteel does 3D, IFC-compliant detailing models, what are you expecting from "BIM" that it can't do?

    Need Updated Software... Civil 3D???

    Carlson's newer software is pretty slick. However, if you want to do highway work, you're going to need Bentley. 3D models are rapidly becoming standard deliverables, and with the prevalence of Trimble in the machine control market, Bentley i-Models of OpenRoads format data is likely to be...

    HEC-RAS: Ineffective flow limits for bridges at channel bends

    You need to identify the direction that water is flowing, which isn't perpendicular to your bridge. Your bridge is skew. Align your ineffective flow areas to the skew angle. I would consider the water flow to be oriented at something like your left 22.5-deg expansion limit, and would rotate the...

    AutoCAD 2013 Installs as 'Student Version'...But it is not Student Version

    The software is the software, is it a student license? And was a student license previously installed on the workstation AND are you opening a file that was created or saved in a student version of the software?

    PE Rates in California

    What you need is YOUR licensed KC engineers to become licensed in CA. Cheaper and ethical/legal.

    Revit LT vs. Revit Structure

    It looks like the main one is that you can't do worksets. If you're a stand alone user, it won't matter. If you need five people developing the model concurrently, it's a deal-breaker. Other things don't seem to matter as much... reinforcement/trusses may be a deal-breaker as well if you're...

    Civil3D always started as AutoCAD

    You are opening it with the "as AutoCAD" profile. You need to edit that part out of the shortcut you're clicking on. Alternately, you can browse to the right profile in the Start Menu and turn that into a desktop shortcut...

    pre and post development runoff calculations

    Does a 7500 sq ft lot require a permit? I would start with the Patterson, NJ city storm water ordinance... unless they're big enough to have a manual. I don't imagine you'd need to do much more than capture downspouts and maybe outlet to a rain garden on a lot that size.

    Flood Mitigation - Modeling Existing Developed Areas (With / Without Detention)

    It certainly isn't how I'd do it or anything I'd approve.

    BIM for construction materials manufacturer

    http://bim.psu.edu/Project/resources/default.aspx BIM is a goal-oriented process, not a product or a model. What are your aims for BIM? Is it to make Revit content for their clients? If so, that's fairly straightforward.

    AutoCad 2000 / 2013 migration

    Try the AUGI forums. I don't see why, AutoCAD is so bloated to maintain backwards compatibility. Few commands have been retired, but if your LISP routine called one, then it would go bang I suppose. Why don't you download a one month trial version and test everything? I'd take my own word over...

    Saudi Arabia civil site design standards?

    Hmm, an ex-colleague is is part of the PMT for a flood control project in Jeddah. Program tasks include developing the City Storm Water Masterplan.

    HEC-RAS Bank Stations

    HEC-RAS is a one-dimensional model and divides the flow into left overbank, channel, and right overbank flow areas. It computes a friction value for each of the three, distributes the water to get equivalent WSE (IIRC) and then outputs a WSE for the cross-section. Something in the balance...

    HEC-RAS bridge model w/ "scour" hole

    Add the hole and mark it permanently ineffective flow?

    Risk assessment in Finite element Modelling

    If your project is funded, then you have to look at all the potential issues that could affect their investment. Hardware failure, data loss, you becoming sick or worse, those are all loss events. There is also the potential that someone else is researching the same thing as you in parallel and...

    bridge scour analysis (pier, footing, piles)by HEC-RAS

    Read HEC-18. http://www.fhwa.dot.gov/engineering/hydraulics/pubs/hif12003.pdf HEC-RAS evaluates the worst-case scour considering erodible material. States typically have regulations regarding how to evaluate scour and ensuring that scour protection is in place to the determined depth. Scour is...

    Small Civil/Surveying Firm Project Manangement Software

    I use Excel. We work in a team of 4 people or less, and don't need anything fancy. We all get together and talk and track milestones once a week. It takes 15 min or less, we update the spreadsheet and carry on.

    Justifying Speadsheet Calculation Against Modelling Software

    I'm not sure that your method is not "traditional." Software applications like SWMM which would usually be used for this nowadays haven't been accessible for very long. You seem to have come up with a few scenarios, but my primary question relates to Tc and how many alternatives you considered...

    HEC RAS - Modeling winding river in high flow conditions

    Considering that a typical channel floods its banks in a 2-yr recurrence storm event, there is enough flow on the right overbank for the skew to be considerable. There is also the constriction on the left bank at the bridge which will shift flow across and cause even more head loss on the...
