Form Work for Footing in Place at 1620 S Fillmore in Denver

December 31, 2008


Beth Freeman and I went out to visit the project at 1620 S Fillmore St in Denver. The form work and rebar was in place for the foundation pours and I did that inspection. With the typical Denver inspection schedule we’ll go out two more times to inspect the vertical foundation walls, the foundation drain and the basement wall waterproofing.

I’m quite impressed by the vertical cut that the excavator was able to put in place and the turret forming is interesting.

Don’t Make Your Solid Blocking Too Solid – Attic Ventilation Requirements

December 30, 2008

I was at a job site today and noticed that the contractor had used blocking between trusses where the blocking was large enough that it actually blocked off the ventilation from the soffits.  They’re going to have to go back and put holes in the blocking to meet the ventilation requirements.

Therefore it seems like a good time to review the ventilation requirements in the International Building Code.

First off, you need at least 1″ of airspace between the insulation and the roof sheathing. The venting must have a total area of at least 1/150 of the ventilated area and at least half that area must be in the upper portion located at least 3′ above the cornice or eave vents. So where you have a 3,000 sf attic you’d need 20 sf of venting with at least 10 sf of that in the upper portion of the roof.

The International Residential Code states that no more than 80% of your venting can be in the upper portion of the roof, the IBC does not have this requirement.

Where you have a vapor retarder with a transmission rate less than 1 perm on the warm side of the insulation you can reduce the venting area requirements by 50% to 1/300.

Finally remember that openings for ventilation need to be covered with material that has a minimum 1/8″ openings and a maximum 1/4″ openings.

I have decided to start another daily architecture blog called ARCHONNECT.

The blog is primarily targeted for our clients, prospective clients, contractors and staff. It has been a great success and I have more to say but this time to a slightly different group.

There is room for a blog dedicated to the daily questions of architects, interns, students and educators. Through ARCHONNECT I plan to create a sounding board that will improve architects and further strengthen EVstudio.

Please support ARCHONNECT and let me know any topics for discussion on either site.
