   Revised Problem Statement
Ultimately, the team’s mission is to create a
  ceiling for a studio apartment that will be
  both functional and cost efficient for the
  apartment contractor, as well as
  customizable, creative, and useful for the
  tenant.
Our idea uses Armstrong Industries’
 strengths, while allowing for future
  advancements to become reality.
Black Box Model
        Concept Generations
The parabolic curved
 light fixture allows
 to use the full
 potential of the light
 emitted from the
 bulb throughout the
 room.
       Concept Generations
A thin layer of gas (inert, Argon) would be
  sealed in between two panels to hamper
  sound waves.
       Concept Generations




A thin layer of wood backing would allow for
  additional storage, and fetter sagging.
       Concept Generations




Small, metallic specs would be placed in the
 tile to reflect more light.
Concept Generations
          A drop ceiling would
            cover up the use of
            acoustical foam,
            which would aid in
            sound proofing and
            a fire proofing.
        Concept Generations




The ceiling system would encourage modification
  and customization, including the ability to add a
  Wi-Fi router or speakers, or other
  advancements for the future.
Concept Generations
          The contrast of colors
            would create an
            illusion of space and
            openness, give room
            for recessed lighting,
            and allow for easy
            accessibility to air
            ducts, wires, and
            pipes.

           Materials List
The quantities obtained in the table were
analyzed for a typical sixteen by nineteen
foot studio apartment
The costs in the table were tabulated from
Armstrong and retail distributor values
The average total costs per square foot
was approx. $30.62 in materials
The Complexity Factor was 1.3
Taking materials and labor into
consideration, the entire project as of 2017
dollars would be $13793.51

        Engineering Analysis
Cost Calculations for one square foot:
   Panels: $4.55 per square foot
   Cables: $0.18 per foot– Approx. 1 foot cable per
    square foot = $0.18 per square foot
   Suspension Clips: $1.56 per foot cable = $1.56 per
    square foot
   Aluminum: $11 per square foot
   Plywood: $10 per square foot
   Paint: $20 per gallon—Approx. 5 gallons for the room
    = $0.33 per square foot
   Light bulb= $3 per bulb = Max of $3 per square foot
Total: $30.62 per square foot
     Engineering Analysis


Max budget was approx. $80- 120 per
square foot
The team calculated $29 per square foot
This is relatively cheap and ideal for a
studio apartment owner
        Concluding Remarks
Met Our Customer Needs
   Studio apartment tenants
   Armstrong
Within Budget
Adaptable for the future
