Seeking someone skilled in entering topography for my new house

Recommended Posts

I am purchasing a new home and I have really enjoyed using Chief Architect to do what if scenarios on my property.  My new lot is much more complicated (on a hill).  I am looking to hire someone to research the topo maps and setup my initial state for my house and lot.  I have the blueprints for the house built in 77 and have already entered them.  But the lot topography is a bit much of a time learning curve for me at this time. 

 

I assume there is someone here who can do this for a fixed price or hourly rate.

 

Thanks,

nbmorgan

Not sure what area you are in but it is not likely that you will be satisfied with public topo maps for your lot elevations.  They will give you a general idea on a very large lot but not detailed enough for proper drainage and planning.  If you have access to a builders level and tripod you can lay out a grid and collect some pretty accurate measurements in a few hours and enter that into Chief.

Around here topo maps/ grading plans run about 15 grand so I don't get them with every job, only the projects that really need them.

Are you saying CA doesn't have a "Lot Planner" module similar to Room Planner, where you could walk around the lot with a handheld GPS device and record the datum on the lot site for instant topo maps?

 

Where is that suggestion forum now?

room planner doesn't have that either, wouldn't that be nice.

Depending on how complicated your lot shape is you could just get  a builder or other how haw a laser lever and get a prity good idea then create a model from the levels he give you from the level. Way cheaper

Not sure how that would work with just a laser level, since the laser would only give you the z coordinate... and without the x and y coordinates of the z, that info would be useless.

I use chief all the time for this kind of stuff.  I make models all the time for ideal lot placement.  Typically on lake lots with heavy topo and involving basement / stem wall foundation construction.

 

You can do some amazing things with Chief,....just have to think outside the box a little sometimes.   I do cut/balance calcs as well.

 

Not too hard at all!

 

Here is a recent example.  (skip to 1:30 in first vid for the "3d" example) This lot had 22' of fall across bld envelope.  (I am talking the client and owners in the video...but you get the idea)  @ 7:20 I go into driveway..etc.

 

Second vid the foundation "design" suitable for cost estimating.  (after optimized)  Cool part at 2:45 where you can really see what you are planning foundation wise.

 

 

Second vid is the foundation design (so we can do a rough cost estimate)   It will be engineered at a later date but done enough of them to cost it from this model.

Thanks guys.   The terrain is just standard modeled.


The prop lines and set back are sidewalks (used for 3d visual purposes)


The transparency setting and can be used to make all the grids.   Just the stock black tile patter with whit joints.  Resized, and applied to a CAD poly line solid in the first vid to figure out best initial placement.


This works really easily and can result in some surprises.   There are times I have found a much better overall solution when looking at it this way vs a story pole and laser on site.   In fact, I now will only work this way when I have to set a critical elevation.

 

Our surveyor charges aprox 600-800 for a topo.   Cheap considering each foot of foundation is a few grand not couting veneer material.    Setting a home right from the get go it a HUGE step.

      Does anyone have a site to OBTAIN MORE PLANTS THAN IN THE CHIEF CATALOGS?  I do a lot of landscape design - and really could use MORE PLANTS ...........
      2nd question - EASIEST WAY TO ALTER THE 2D PLANT IMAGE IN COLOR (versus most plant images in 2d are black/white) ... AND STORE THE 2d symbol along with the plant etc

      I think I am missing something. I want the "Text Below Line" on my Elevation Camera Labels/callouts to show the sheet number. And make this the default. Does any one know how?

      Newbie with Essentials 2019 on iMac.  The house is fine, it all works.  Now for landscaping.  The fence is fine, shows in 3D.  I added Terrain Perimeter, shows in 2D, not 3D, but that seems okay.  I opened Terrain Specification, selected Materials/Terrain/Dirt/OK, but nothing changes in 2D or 3D, no dirt shows.  For 3D Camera I removed backdrop, no background color, turned on Generate Sky/Haze, looks good in 3D, just no dirt.
       
      I'm obviously missing a step to get the dirt to appear.  What is the trick? I expected the dirt to hide the foundation, appearing at the bottom of the fence,
       
      Thanks!

      Hello I'm having an issue w/ my elevation. How do you get it to update automatically what layout page it is on?

      Good day, all of you.
      Need your kind attention to finalize a front elevation of a house. The plan is attached Aamir77_gutted_MHD_Rev1.zip to the post. Please confer me a little segment of your precious time. I have been up to 3 types of front elevation which are also attached herewith as pictures. Thanks in advance.
