I checked on the City Of Rifle. They utilize a 40 psf ground snow load and have not had any trouble with it. We still want to maintain the flat roof of 40 psf (57 psf ground load) for the county since other areas of the count y up to 7000ft. of elevation get much more snow than Rifle. Any future projects at the airport should be designed based on a 57 psf ground snow load. I w iU look at ways to better define our snow load requirements with future building code adoptio ns. It is confusing.

Based on a roof snow load of 40 PSF and a ground snow load of 40 PSF VP has used the "B" diagram for the roof loading. You will always have at least a 40PSF snow roof load but you are using a calculated load for drifting based on the 40 PSF ground snow load, so the drifting starts with a 28 PSF load and then the drifting is added to that number. Please let me know if this is what you have intended. If we need to maintain a 40 PSF load then add the drifting load on to that we would be using a 57 PSF ground snow load, we didn't think that was the intent behind the code. Thanks for your comments.

Hopefully, any periotic commercial fire district inspections would identify if too much clutter collects in the storage areas . My only concern with the attached letter from VP is i f the drift load was determined from a 28 psf (shown under their SMS statement) or the minimum 40 psf. If t he design does n o t change with e ither loading than I have no concern . 2 \ .

On the exiting from the tenant areas I have a couple items. In the past when we have done this type of building the area labeled Storage gets used in a variety of ways, from office area to shop to support space . What about if we added an EXIT sign over the pair of doors going into the hangar. That would include doors 101, 104, 107, 119, 122, and 125. We currently have the frog eyes for egress lighting in those same rooms now. On the structural items we reviewed yesterday I have attached a letter from the VP Engineer. Please take a look and let me know if this gives you what you want from them. Thanks and have a great weekend . Kevin Kevin C.

That being said, I have some concerns about exiting from the offices through the storage rooms A-Fas per section 1014.2(4) of the 2009 IBC . My concern is these storage areas might have storage items that block the exit access path or make it difficult to find the exit access path in a dark or smoke filled room situation. A discernible path of egress could be difficult depending on a variety of items 3 stored and the variable arrangement of the stored i tems. Just marking an exit on the floor woul d not be a viable solution. Also , I believe the code does allow access throu gh the general ai rcraft hangar to an exit once a person gets into the hanger. Storage hangers tend to have a very discernible path of egress due to the open and not cluttered natu re of the hangar. It is the storage closets or rooms that could be a problem .

We have since broken the 28 day breaks on this pour sampling and it has come back at an average of 5,200psi on the 5,000psi mix so we are fine. We will continue to be diligent with the cold weather concreting and will continue to have our engineer review the results. I am happy to share the reports from Ground Engineering with you -not sure if you want more emails. Ground Engineering will ultimately be writing the special inspections letters at the end of the project. Thank you. Thomas A. A. Cook Vice President tectonic management group, inc .

We have been in contact with our structural engineer -he has indicated that ACI 306 Winter Concreting methods should be used. We do have blankets and two thaw units in place to enable backfilling and protection of concrete forms both before and after pours. Hot water is being added to mixes to maintain temperature during pours. We are using Ground Engineering for the testing work -they are taking samples, checking concrete during pours, checking rebar and performing compaction tests. Results to date are within specification. I will forward the reports to our structural engineer for review to see if he has any comments. We would like to continue with the hangar foundation to allow us to continue with steel erection in the near future. Thank you. Thomas A. A. Cook Vice Pres 'dent tectonic managem er1t group, rnc.

Some days have been upper 20's but more than a few days have been much colder including some days in the single digit. We assume concrete samples have been taken and request that the engineer review these reports to determine if the cold weather has been mitigated with the concrete work.

We have started our review of the plans. They appear to very complete and comprehensive. Thank you for that. It sure makes our job easier and the project smoother. The snow load listed on the steel building VP Buildings General Notes is in error. It list a 40 psf ground snow load and a 25.2 psf or 28 psf flat roof snow load. The flat roof snow load should be 40 psf. The architectural and structural drawings by Tectonic appear to reflect the required 40 psf snow load requirement for a flat roof. We will continue with the review. Hopefully this is just a typo or a misread on my part. A letter confirming the snow load meets our minimum requirement from the steel building engineer can be added to the file to clarify the loading.
