sustainable finish.
Which one of the following finishes should the architect specify?
A. Lacquer
B. Epoxy paint
C. Chrome plating
D. Powder coating
CORRECT ANSWER
D. Powder Coating
When metal coatings are required, powder-coated fabrications can be specified as a
solvent-free application. The powder overspray can also be reclaimed for reuse.
Question 2
1
@THE STUDY VAULT
,An architect is designing a children's playground in a residential development. The
playground site is an open grass area that is prone to ponding rain water. The developer
has asked the architect to reduce the ponding without regrading.
Which one of the following should the architect include in the playground design?
A. Area drains
B. Slotted concrete pavers
C. Subsurface perforated piping
D. Brick pavers with open joints
CORRECT ANSWER
C. Subsurface perforated piping
Subsurface perforated piping is used to control and remove soil moisture.
Question 3
A high ratio of surface facade area to building area is what we look for in maximizing...
CORRECT ANSWER
Natural daylighting

, patients with breathing difficulties. The hospital has asked the architect to choose a
roofing system that minimizes health risks.
Which roofing system should the architect specify?
A. EPDM
B. Modified bitumen
C. Four-ply built-up roof
CORRECT ANSWER
A. EPDM
EPDM membranes have a minimal amount of seams which are joined together with
adhesive. This roofing system is the most appropriate option because it is the only
system that will not pose a risk to the health of hospital patients during its installation.
Question 5

CORRECT ANSWER
A shallow foundation (a deep foundation will not be required)
Question 6
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?
