PPD PRACTICE TEST
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?
|B.||Slotted concrete pavers|
|C.||Subsurface perforated piping|
|D.||Brick pavers with open joints|
Subsurface perforated piping
Subsurface perforated piping is used to control and remove soil moisture.
Agreed Victor and to add...I believe there is a practical component to this question. It is a "children's playground", therefore exposed drains, concrete pavers, and brick pavers w/ open joints are all tripping hazards. The brick pavers open joints even hint at safety and ADA compliance.
Subsurface, or below grade drainage, satisfies/eliminates the civil engineering and saftey/ADA compliance messy stuff. Just my 2 cents.
