$($a$)$ Goldratt $(1997)$ proposed the Theory of Constraints $($TOC$)$ and Critical

Chain Project $($CCP$)$ scheduling, which provide the concepts for achieving

effective activity duration control. Literatures show that the TOC and

Critical Chain concepts are increasingly being accepted and applied in

various industries. For example, the application of TOC and Critical Chain

concepts in the construction industry is to manage buffers effectively in

scheduling planning and control.

i$.$ Buffer management aims to generate a rigorous construction plan

that protects against uncertainties and reduces the potential impact

of construction changes. With any relevant examples, explain the

buffer management in construction field in detail.
