Coordinates

  • Turn on Project Base Point (circle with X by Architect, moves relative to the survey point) and Survey Point (triangle with dot by Civil Engineer), VG > Site > check Project Base Point
    • Revit has project north and true north (stateplane grid north). Within a site/floor plan properties, change orientation to true north, then Manage > Position > True North
  • Assign coordinate values to the survey point. Manage > Coordinates > Specify Coordinates at point. (Revit 2016 Help - Relocate a Project by Entering Points). Use the Unclip option to move the point with respect to 0,0 then the point shows the actual coordinate value. If you don't use the Unclip option, then the survey point shows 0,0 and moves off the screen.

Revit Project - Residential Drawing

Revit Setup

North

  • Note, the best method is to create/draw your building with the north face of the building pointing up in Revit.
  • The ResA.pdf Site Plan shows North is pointing to the left side of the plot. If you draw/create the building with this orientation, Revit assumes north is the top of the page, so this will cause problems (1. elevation view names will not match actual building orientation, 2. if you rotate your viewports in a sheet, the dimensions/text/symbols might not properly align). If you did this by mistake, the solution is to adjust true north, see Autodesk Revit Help - Rotate True North and will have to manually change the elevation view names.

A360 Drive

  • Recommend logging into Autodesk 360 (jeffjensen normal) and create a working folder ArchitectDrafting-Madsen
    • Initially - need to open Revit, save the project locally, then move the .rvt file into Autodesk 360 folder. Then right click and Open the .rvt from Autodesk 360 folder.
    • to login, right click the Autodesk 360 icon in the system tray and select Sign in
    • example Autodesk ID is jeffjensen or e-mail address jefferyjjensen@gmail.com and password NormalOne
    • I'm unable to open a Revit file saved in Autodesk 360 directly in Revit. As a workaround, I use windows explorer, right click on ResidentialA.rvt Revit file and select Open from the context menu. Then it appears Revit will sync any changes back to Autodesk 360 (not sure where the cache is stored locally).
    • Autodesk 360 is very slow, will take about 5 minutes once logged in before your files are available to open.

Res06-A Framing and Roof Plans

Roof Materials

Roof Vents

  • Why Ventilate Roofs? “To fight the enemies, heat and moisture, you must ventilate year round. Heat in unventilated attics may cause temperatures to exceed 150 degrees causing damage to shingles, roof sheathing, and possibly radiate to the living area. Moisture, being the #1 enemy, causes rot, mildew, mold, paint blisters, and renders insulation to be ineffective. Proper ventilation reduces energy bills, winter ice build up, and eliminates mold/mildew which can lead to major health problems. By ventilating, you are extending the life of shingles, insulation, and other building components.” (Lomanco Vents - Product Catalog)
  • “Upper ventilators shall be located no more than 3 feet (914 mm) below the ridge or highest point of the space, measured vertically, with the balance of the required ventilation provided by eave or cornice vents. Where the location of wall or roof framing members conflicts with the installation of upper ventilators, installation more than 3 feet (914 mm) below the ridge or highest point of the space shall be permitted.” (International Residential Code for One- and Two-Family Dwellings Section R806 Roof Ventilation)
  • Whirlybird “turbines will work at maximum efficiency when the top of the turbine is over the roof peak. This will allow the wind to hit the turbine from all directions.” Lomanco Support System - Why aren't my turbines spinning?
  • “Turbines will work at maximum efficiency when the top of the turbine is over the ridge line. When installed at the peak of the roof, turbines will be exposed to the wind from all directions. On most pitched roofs, you will want to cut the hole about 18 – 24 inches from the peak of the roof.” (Lomanco Support System - How far down the peak should turbines be installed?)
  • Total Net Free Ventilating Area (TFNVA) = area of attic floor space (ft2) / 300
  • Exhaust Area
    • 8” diameter whirlybird provides 50 in2 of exhaust (Area = p r2 = p * 4“ * 4” = 16 p = 50.3 in2)
    • 10“ diameter whirlybird provides 78 in2 of exhaust (Area = p r2 = p * 5” * 5“ = 25 p = 78.5 in2)
    • 12” diameter whirlybird provides 113 in2 of exhaust (Area = p r2 = p * 6“ * 6” = 36 p = 113.1 in2)
    • 14“ diameter whirlybird provides 153 in2 of exhaust (Area = p r2 = p * 7” * 7“ = 49 p = 153.9 in2)

Floors

  • In colder climates the footing needs to be placed below the frost line, so typically have stem walls and wooden floors or basements.
    • Figure 3-0 Concrete Stem Wall - Oak Ridge National Labs
  • In warmer climates the footing and floor can be placed on the ground/grade. This is more economical than the stem wall construction.
    • Figure 5-0 Slab-on-Grade/Ground with Integral Grade Beam, Foundation Design Handbook by Oak Ridge National Laboratory
    • Figure 5-0 2012 International Residential Code - Figure R602.3(1) Typical Wall, Floor and Roof Framing
    • “Three types of substructures using simple wall footings. The slab on grade is the most economical under many circumstances, especially where the water table lies near the surface of the ground. A crawlspace is often used under a floor structure of wood or steel and gives much better access to underfloor piping and wiring than a slab on grade. A basement is often specified on a steep slope or in regions where the frost line requires deep footings.” (Fundamentals of Residential Construction, 3rd Edition by Allen, p. 195)

  • “The area of floor used for parking of automobiles or other vehicles shall be sloped to facilitate the movement of liquids to a drain or toward the main vehicle entry doorway.” IRC 2012 R309.1 Floor surface. Try using a slope of 1/4” per foot = 2.08% approximately 2%
  • “Concrete slab-on-ground floors shall be designed and constructed in accordance with the provisions of this section or ACI 332.

The specified compressive strength of concrete shall be as set forth in Section R402.2.” IRC 2012 R506.1 General
  • “Vapor retarder. A 6-mil polyethylene or approved vapor retarder…shall be placed between the concrete floor slab and the base course…” IRC 2012 R506.2.3 Vapor retarder. Clark County Amendments call for 10 mil, see Southern Nevada Amendments to the 2012 International Residential Code

  • “Place the posts on post footings. If a vapor retarder has been stretched across the footings, rest posts directly on the vapor retarder. If no vapor retarder is present, use pieces of 15-pound asphalt-impregnated building felt between concrete post footing and end of post. If a column base anchor is used to anchor the post to the foundation the 15-pound asphalt-impregnated building felt may be eliminated.” (American Plywood Association - House Building Basics, p. 9)
