Civil Engineering Calculations
This app adheres to apple’s recommendation of a universal binary; Meaning the purchase contains both the iPad and iPhone versions for the same price. So if you have an iPod/iPhone you’ll get that version, but if you also have the iPad you’ll have that version too. The ‘Lite‘ version of this app does not support the iPad.
This program was designed to provide Civil Engineers and Land Surveyors with a quick way to calculate or check points on portions of a roadway profile, area calculations, drainage/flow calculations, traffic counts, etc. Great for use in the office, while checking through plans, or in the field when you need some quick effective calculations.
This tool is great for plan checkers, surveyors, and engineers who perform repetitive vertical curve grade calculations as well as for checking slopes and elevations, and now angles. Great for Civil Engineering Students, and Professionals.

Other Functions
Please let me know of any other feature requests. I will continue to update this with any ideas that I receive (Website or App Store comments).
Loks very impressive especially for field use
I’m an Australian Civil Engineer and would certainly purchase if it worked with metric distance/area??
Your advise much appreciated
The traverse function is based on ‘units’, and while it displays the letters ‘SF’ for the area the calculations technically function the same regardless of if you are entering centimeters, feet, or kilometers. It really returns square ‘units’.
Looks like a great App but it could use a help section. I can’t seem to figure out how to clear points once I enter them with the GPS.
Something else that would be nice is if it could change GPS Lat and Long to x,y for use in ACAD
Thanks
By Default the Data that it stores is in a Localized X, and Y Coordinate Format. the localization is based on the initial GPS location pulled. For approximate (iPhone accuracy) you could initialize the GPS at a benchmark location and then proceed to the locations you need coordinates for.
Hi! I am a QS and decided to give this ap a try! I love it. Although I have not tried it out yet at work. It seems so much fun to use. My query is this- I work on road construction and one If my tasks involves gully and MH pipes. I need to find the depth of the pipes at different depths. Will this app aid my work??
Thanks! I hope u release more apps directed towards civilise and qs work!!!
Quantities haven’t been a real focus, but I will consider some improvements to assist in this. The tangents section can assist in determining distance, given a slope, to reach an elevation. So although this app may be able to augment some of your work, it hasn’t really taken the QS field into consideration. I’ll see if I can come up with some better tools for your field.
Is there any way that you could inculde bridge pile formulas (Modified Gates) and a way to figure bridge hunches or at least the dead load deflections.
I’m really inexperienced in structural calculations, but I will certainly look into it. Dead load deflections would certainly be obtainable. Pile Formulas, and bridge hunches are definitely possible, but would require quite a bit of time to develop.
Hi, I really like this app. Do you think you can add in some things of Soil Mechanics. For exapmle, Plot Effective Stress vs Depth given the total unit weight, water table dept, etc. Also Soil Classification. Bearing Capacity for piles.
Thanks
There seems to be a lot of requests for this feature. I’ll have to start working on it.
I just purchased this app, and I have a couple of comments. Is it possible for you to add definitions of the various formulas on the bottom of each page. For example, what “Q” stands for, or what CFS stands for. In our day to day work we may use slightly different units so we would have to convert the results. It would be a good idea to place “foot notes” under each formula defining the formula use and what each letter means. Thanks.

does the calculator work in metric or only imperial. Alternately can one convert units?
