I'd prefer to use a door with a 20 gage steel skin (.040 inch). Am I off base? Andy (Unregistered Guest) Unregistered guest Posted on Wednesday, October 20, 2010 - 11:01 am:    .015 sounds very light. Most commercial overhead doors are at least 24 gauge (.0239). Coiling doors start at 22 guage. I'm assuming the door is insulated with foam. I would recomend at least a 22 gauge skin on each side of the foam insulation. What size is the door and how often is it used? The answers to that question might make me bump it up to 20 guage. I think you are on base Lynn Javoroski CSI CCS LEEDŽ AP SCIP Affiliate Senior Member Username: lynn_javoroski Post Number: 1127 Registered: 07-2002 Posted on Wednesday, October 20, 2010 - 11:48 am:    The door is large - the Owner wants one door for 2 ambulance bays (well, one at each end); so the door(s) will open and close each time either of the 2 ambulances comes in or goes out. The hospital is in a small mid-west city, though, so it's not like it's in downtown Chicago. And, yes, foam insulation is part of the door sandwich.

It doesn't do much, though, when the drivers don't wait for the doors to open all the way - apparently a common occurrence.

Try using a Rytec door. They are phenominal, and wicked fast!

Yes, it's THAT sort of a project. (I successfully spec'd a Rytec door in another project, toured their factory, and rejected a substitution that would not have been as good, so I know all about Rytec - they are wicked fast and of great quality). I'll have to bring up the "not waiting for the door to open" issue at the next meeting.

Nathan Woods, CCCA, LEED AP Senior Member Username: nwoods Post Number: 354 Registered: 08-2005 Posted on Wednesday, October 20, 2010 - 05:07 pm:    Lynn, send me an email to "nwoods@mve-architects.com" and I will send you a video I made of the door I installed at underground garage below a multi-family housing project. The residents were driving into the previous gate atleast once a week. A driver in a Porche would have a hard time accellerating in time to hit the Rytec. We actually had to slow it down in software settings because it was freaking people out :-) Lynn Javoroski CSI CCS LEEDŽ AP SCIP Affiliate Senior Member Username: lynn_javoroski Post Number: 1130 Registered: 07-2002 Posted on Wednesday, October 20, 2010 - 05:10 pm:    I've seen the video on the Rytec web site, and I've used the ones we installed in the Pier Wisconsin museum project in Milwaukee. They are very cool. If you can manage a visit to their factory in Jackson, WI, do so. I'll try one more attempt to make my case for the door, but since I'm a cynical optimist, I don't hold out much hope. Andy (Unregistered Guest) Unregistered guest Posted on Wednesday, October 20, 2010 - 01:35 pm:    If they are large doors, I think you want at least 20 gauge.

I've told the team that I will be specifying the heavier door and why. If the Owner/CM want to take a chance with a lighter door, it'll be on their heads. I'd still prefer the Rytec...

I don't know how the CM process works south of the border, but up here it is usually the architect that issues the RFP for the CM services on behalf of the Owner and I know that in our RFP documents we specify minimum number of competitive bids. Only in exceptional and unusual circumstances are less than 3 bids presented. Also it depends on the CM delivery method...we mostly use stipulated price (CM's 90% CD budget is used as the bid price and the contract essentially reverts to a standard DBB type of Contract) but have recently had a couple projects that have adopted a cost-plus Contract. Ride it like you stole it!!!

We are to produce the documents, and the CM is supposed to manage the project. However, the CM did not provide Divisions 00 or 01. We wound up doing that - under protest and with PDFs because I refused to send Word docs (we pay for those from MasterSpec and I don't think our license would let us). My take on the CM is that 6 months ago he couldn't even spell it, and now although he can and has learned a lot of new words, he hasn't a clue what they mean or what his role in the project is.
