PPD Exam- Amber, NCARB, EW, Ballast: Q’s & A’sAn architect is designing a new computer lab as part of an addition to an
existing high school. The owner has the following requirements:
-The lab must accommodate 30 computer workstations.
-Flexibility to switch between group and individual learning furniture
configurations.
-The space should minimize sound transmission between adjacent spaces.
Which design should the architect consider?
A.Raised accessible subfloor with carpet flooring
B.Underfloor duct raceways with resilient flooring
C.Evenly spaced floor boxes with acoustic wall panels - Correct answer: A
CORRECT RESPONSE
Raised accessible subfloor with carpet flooring
A raised floor will accommodate the flexibility needed for different furniture
configurations and carpet is recommended for minimizing sound
transmission.
The preliminary bids for a 40,000-square-foot high school addition are over
budget. The polished concrete floor originally specified for the floor assembly
costs $6 per square foot. The owner requests a seamless flooring product and
the contractor suggests the following alternative flooring materials:
Vinyl composition tile (VCT): $1.50 per square foot
Luxury vinyl tile (LVT): $4.50 per square foot
Epoxy flooring: $1.75 per square foot
What are the cost savings of switching to the preferred alternative flooring
material?
$ _______ - CALCULATIONS
1. Cost of the originally specified polished concrete flooring material: $6.00 x
40,000 sf = $240,000
2. Cost of the preferred alternative flooring material, epoxy flooring: $1.75 x
40,000 sf = $70,000
3. Cost savings of switching flooring material: $240,000 - $70,000 = $170,000
,An architect is working on a seven-story L-shaped office building in the
northern United States. There will be a three-story glass-enclosed atrium with
masonry walls between the two wings of the building. The owner wants the
walls within the atrium to have maximum solar gain in the morning only.
Which building orientation should the architect use? - With building
orientation D, the atrium faces the east, which is the best direction for
receiving the maximum morning-only solar gain requested by the owner.
An architect is determining the size and number of doors for a large,
rectangular assembly room that will be used as an exhibition gallery. The
assembly room will be 150'-deep by 250'-long. The AHJ requires that all
means of egress components other than stairways use an egress capacity
factor of 0.2 inches per occupant. All assembly room exits will use double
doors.
How many 60-inch clear width double door exits are required?
_______ double door exits - 1. Determine room size: 150 feet x 250 feet =
37,500 square feet
2. 37,500 square feet / 30 square feet per occupant (occupant load factor for
an assembly space for exhibit galleries) = 1,250 occupants
3. Egress components other than stairwells require multiplying the occupant
load served by a means of egress capacity factor of 0.2 inches per occupant.
4. 1,250 occupants x 0.2 inches = 250 inches of egress width required
5. 250 inches of egress width / 60 inches (double doors) = 4.17 doors,
rounded up to 5
Section: Codes & Regulations
An owner requests a 100 kW solar array. City ordinance requires solar
equipment to be concealed from the public right of way. The architect needs
to locate the system on the site plan to maximize performance.
Drag the 20 kW solar modules onto the site plan to meet the requirements.
Not all solar modules will be used. - Five solar modules on the part of the
building with a flat roof.
, Solar collector panels should be oriented within 20 degrees of true south and
not be shaded by nearby structures, terrain, or trees. The modules are 20kW,
which means that five units are needed to meet the owner's 100 kW
requirement. The panels should be placed on the part of the building with a
flat roof to allow for proper sun angles and to conceal the equipment as
required by zoning ordinance. The panels should be arranged away from
parapets and the stair shaft to avoid shading. The panels should also not be
installed over the roof drains to allow for ease of maintenance access.
CALCULATION
1. 100 kW (solar array required by owner) / 20 kW (kilowattage of each solar
module) = 5 solar modules needed
An architect is designing a five-story addition to an existing building, and a
separate foundation needs to be designed to support the addition. A
subsurface investigation reveals that the soil on the site is predominantly
coarse grained.
Which type of foundation is most appropriate for the new building?
A.Shallow foundation with stepped footings
B.Shallow foundation with cantilever footings
C.Deep foundation with micropiles
D.Deep foundation with friction piles - Correct answer: B
CORRECT RESPONSE
Shallow foundation with cantilever footings
Coarse grained soil on the site indicates that a deep foundation is not
required.
A cantilever footing addresses the need to build against an existing building
An architect is designing a building renovation and needs to add an accessible
ramp at an existing entrance that only has stairs. The ramp needs to
accommodate a 42" vertical rise.
Based on the Americans with Disabilities Act, what is the minimum length of
the accessible ramp excluding the top and bottom landings?
_______ feet - CORRECT RESPONSE
47 feet
