Room Options

 

Current Options
-One Drexel Plaza
-AEL 279
-Hess

 

One Drexel Plaza Conclusion: NOT Feasible

Pros Cons
-Ample floor space -Space is over $7.00 per square ft and whole space must be rented
-Very high ceiling  -Unconditioned space, no circulated air, not habitable
-Private, we won't be bothering anyone -Space would have to be outfitted with air-conditioning and heater $$$
-Easy access for large sections of gantry, easy assembly space-wise -Not ascetically pleasing for potential demos w/clients

 

AEL -279 Conclusion: Very Difficult to Impossible

Pros Cons
-Room condition is nice/accomadable for demos -Low 10ft ceiling
-Within close proximity of MEM Department -After moving conduit and recessing vents we only gain 1'5"
-Close to other labs -After removing vents entirely we only gain 2'6"
-Already moved partially -Difficult/impossible access for large sections of gantry
  -Small floor space
  -Classroom close to lab, potentially disturbing other rooms w/loud testing & gas fumes 
 

 

Hess Conclusion: Great Potential -  Best Choice Available 

Overall View of Room

Obstructing Vent

The vent regions in red shown are currently in the way of space that would be occupied by the gantry; thus the vent would need to be shortened.

Close Up of Vent Disconnect Point 

The arrow shows the point where the vent would be disconnected from and then a new diffuser plate would be added. This is simple job that could be done by the students without disrupting anything or anyone: 1 hour 2 People.

 

Pipe Alterations

The regions in red show where the pipe gets in the way of the gantry, outlines in blue is the new path that the pipe would take after alterations.  This is also a simple job that can be done off hours.  The pipe service is simply turned off by a valve and then cut and re-sweat in its new place: 2 Hours 2 People

Lighting Alterations

The lights must be removed. First the power is easily cut off by the existing power switch. Then the wiring is disconnected and capped inside a junction box.  Then the fixture is self is released by simply undoing the chain connection that holds it in place: 3 Hours 2 People

Conduit Changes, Must be done by Facilities...... we don't know what's this conduit.
Pros Cons
-Easy access from overhead ceiling space -Possible long lead time to prepare, move Moshe, relocate false environment, make room changes
-Large room ample space for gantry -Must change some room features (see: room work and ref. pics above)
-Can perform noisy tests after hours with disturbing anyone -Only 10.3 ft ceiling without room changes
-Only room that really fits size criteria  
-Allows for greater level of diversity for false environment  
-14.9ft after room changes!!!!  
-Most changes can be done by grad students NO COST!  
-Add exhaust vent to run gas powered engines for future testing  
 
 

 

 

Civil High Bay Area Conclusion: Great Potential 

Overall Layout of Room

This room can potential be a great test bed if the civil engineering department is not using their Wall Impact test facility.  This would allow us to fit the entire gantry in the floor space and utilize it's highly elevated ceilings! 

Overall View of Room

As you can see there is ample space from the floor to the lowest ductwork (aprox. 24ft).  You can also see how narrow the space is that is not currently in use.  

Unused Area

This is the area in which no testing is taking place.  The gantry could possible fit into this space, however the width would have to be shorten by about 5ft.  

Wall testing area (not sure of current use)

The Wall/Brick testing area would be a great benefit to the overall space of our potential test bed, however if this space can not be utilized then the gantry would have to be resized to a smaller scale.   

 

Pros (assuming wall test area is encompassed) Cons (if wall test area is not encompassed)
-Highly Elevated Space (24ft !!) -Unused space is too narrow (11ft)
-NO RETRO-FITTING OF THE GANTRY -Would have to potentially cut down the width of the gantry to fit this narrow space
-Minimal Construction to get started (ie. moving objects, no pipe rerouting) -Wall testing could be problematic to our environment, sensors and stages (ie. dust, breathing conditions)
-Forklift available for object movement (ie. palettes)  
-Easy access from garage  
-Can perform noisy tests after hours with disturbing anyone  
-Only room that really fits size criteria  
-Allows for greater level of diversity for false environment  
 

 

 

Civil High Bay Area  (Top Floor) Conclusion: Poor due to Height Conditions 

Overall Layout of Room

This room has a good floor space (area enclosed by the purple lines) that will allow us to fit the gantry inside the area comfortably. 

Overall View of Room

As of right now there is a lot of equipment in the way (long lead time to remove) and the height is very insufficient for any type of vertical movement.   

 

X-Y Stage

Currently there is a large I-Beam that translates along the height of the room.  This hinders our height by an additional 4-5 ft, giving us only 8 ft of vertical height.  (unless stage is moved, then we have 12ft).  Also this room would involve more water pipe removal as shown above. 

Water Heaters & Misc.

As seen above, there is a great deal of hindrance from the water heaters and piping.  This limits the gantry to be place in only select places of the room.  

Pros (assuming wall test area is encompassed) Cons (if wall test area is not encompassed)
-Gantry will fit inside the floor space  -Height is too low (12ft)
-Area is well lit -Would have to potentially cut/move/reroute water piping
-Garage allows sufficient space for materials to be brought to work area.   -Wall testing could be problematic to our environment, sensors and stages (ie. dust, breathing conditions)
-Can perform noisy tests after hours with disturbing anyone -Lead time to move equipment would be excessive.  
  -Not exactly sure if Civil Engineering department is still active in testing/experimentation of these facilities
 

3 Potential Options for High Bay.

1.) Use the area that is encompassed by the "Wall Test."  This would allow for the gantry to be built to specification without any modifications or 
     resizing of the framing.

Notice above the white hatched area is the gantry frame.  However in order to do this you would have to move the materials that are constantly 
being moved in through the garage area.  Also Civil would have to cease all "Wall Testing."

2.) Use the area encompassed by the "I-Beam Testing."  This would allow for a shortened width (3ft) and additional length (3ft).  However this is under
     the assumption that Civil would cease "I-Beam Testing" and the steel conduit could be moved aside. 

3.) Use the area not covered by any testing region.  This would allow for a shortened width (6.5ft) and additional length (9ft).  However, this would could be
     potential problematic if the forklift needed to get supplies to the back of the room.
