Ten Minutes in the Street: Profiling and Size-Up No.1
Latest ADD; Let me offer the following two aerial imaged that will offer opportunties for additional dialog and discussion. The aerial of the Delta side provides the greatest insights into what adaptive, reuse and renovation is all about. I'll provide more of my take on this after we get more comments and perspectives. Some key factors relate to the building's reuse and occupancy, the construction features that are evident on the Delta side and what your observations "tell" you from the Bravo side. Also, lets talk about the building's size...30 ft. wide x 190 ft. in length. Things are not always what they first appear to be....
Let's take a look at developing and enhancing your observation, profiling and size-up skills from the street.
We have two images; A view from the street of the Alpha and Bravo side and the other view from the Alpha and Delta sides. Each provides a distinctive view and insights in the structure, occupancy and risk profile of the structure. As with any incident response, there may be very unique or subtle conditions or factors that will influence your strategic decision-making process, risk perspective, the development of your IAP and tactical implementation and assignments.
Barring issues related to incident factors (i.e, fire, rescue etc.) take a look at the building carefully, take a look at its profile, what your experience gauge is telling you, what you may have experienced in the past (RPDM) and provide your insights on any number of the wide range of factors such as; Building, Occupancy, Type, Construction, Systems, Hazards, Risk, Performance, Stability, Fire Load, Occupancy Load, Fire Travel, Smoke Travel, Occupant Travel, Access, Egress, Ventilation Profile, Engine Company Access and hose-line movement, Rescue, Removal etc.
There’s a wealth of discussion points here for us to explore. As always, our individual view from the street may not always be the same, but we can learn from our combined view points.

A couple of things that jump out at me in the aerial shots is are the many large HVAC units on the roof and Side C where the rear shear walls have been removed to create the semi-balconies. I'd be concerned about propane-fired barbecue grills on the balconies and their potential for starting fires if there are any combustibles (tables, chairs, rugs, etc.) there.

Yes, I spent some time "looking" over this beauty at FDIC in person...
The manner in which this structure was renovated creates SIGNIFICANT operational issues, IF we fail to recognize important inherent and modified elements- The structure will not behave in a predictable manner, IF we base our operations on our observations from the A-B sides. If we then fail to understand the observed construction changes that affect the entire bldg. as seen from the Delta side, we are committed to faulted IAP's...

In an old moment-frame warehouse like this, an elevator shaft that penetrated the heavy concrete floors inside one of the frames would be relatively unusual. It's possible that the large structure on the roof is an elevator penthouse, but another look at Side D tells me that there probably was an external elevator shaft in the inset where the glass panels now sit on Div. 2 through 5. That shaft would have been large enough for forklifts and would not have required floor penetrations through the heavy floors.
The stairs from Div. 5 to the roof may have been somewhere else.
The potential lack of an elevator to the roof may be one of the reasons that the restaurant is no longer there.

I think I see one as well, but it is so small that it's not going to provide much vertical ventilation. It is a fall hazard for any truckies operation on the roof, particularly if they ladder that part of Side D.

Here's a pre-reconstruction shot date unknown) of the roof of this building. Note the absence of the rooftop structure that we're considering might be an elevator penthouse next to the Side D inset. A lot of the HVAC machinery, the rooftop garden, and several other features that are present now were not there when this photo was taken. There also appears to be a large sign mounted on Side D at the D-A corner that was removed in the reconstruction.
The Side B neighboring building and the possible freight elevator at the inset on Side D were long gone prior to this shot. You can see what appears to be a loading dock at the footer for the Side D inset, however.
Obviously an iunteresting structural history on this building, regardless of the details.

I agree with Ted, to copy how he put it, Looking a second time, I'm thinking about the parked cars and style of window blinds, and I think I'll agree with DT that there are probably offices on the upper floors, as opposed to apartments. So he's 100% right about higher daytime occupancy, with limited means of egress.

The parked cars might go with the B exposure, it's a much larger occupancy and looks to be an apartment building.
The window/blinds were retrofits required to maintain historical accuracy when the building was rehabbed. The architect specifies that Divisions 2 through 5 are condos. The parking for the condos would likely be on Side D near the stairs.

I couldn't really tell ya on that one. I have a friend who is on Fishers which is a suburb of Indy. I may be seeing him in the future as he may be putting on an extrication class at my station. I would assume that they do have some kind of requirements on sprinklers but I don't know for sure.
