Before backfill begins, what does pipe bedding primarily provide?

Correct Answer

A) Uniform support and protection from point loads

Uniform support and protection from point loads is the controlling requirement: the distractors are related-looking contract or field terms, but they do not match the cited requirement for review item 67.

Answer Options
A
Uniform support and protection from point loads
B
Base the bedding response on paint protection
C
Classify the condition as a way to reverse slope
D
Classify the condition as a substitute for testing

Why This Is the Correct Answer

Uniform support and protection from point loads is the controlling requirement

Why the Other Options Are Wrong

Option B: Base the bedding response on paint protection

Choice B gives Only paint protection. Its specific error: it leaves the work at an informal or incomplete stage, while Bedding requires.

Option C: Classify the condition as a way to reverse slope

Choice C (A way to reverse slope) is rejected because it leaves out the controlling Bedding result.

Option D: Classify the condition as a substitute for testing

In site construction, A substitute for testing is the wrong selection for Bedding: it treats Bedding as optional.

Memory Technique

Link bedding to its book condition; a different condition means a different answer than Uniform support and protection from point loads.

Reference Hint

Open Pipe and Excavation Contracting, 2011; use the index entry or section for "Pipe bedding" to confirm that Uniform support and protection from point loads is the controlling requirement
