Yap and Skitmore [11] and Bassa et al. [29] noted that DCs play a major role in increasing the wastage of materials, resources and rework, while Dosumu and Aigbavboa [30], Zaneldin [31] and Howick [32] highlighted the impact of DCs on increasing project variations, claims and disputes between project parties.
By involving more people in the design phase, leveraging new technology and materials, maintaining quality consistency, and delivering projects faster and with higher quality, CE boosts productivity and prevents errors [52].
ADFs are responsible for producing uncoordinated and incorrect construction documents, specifying outdated building materials or technologies, ignoring the role of the client and behaving unilaterally [64].

However, if Employing Error is less than the quotient, it is indicates that Employing Error has been met, allocating materials according to Employing Error so as to avoid excess allocation.
With the guidance of Employing Error, the Allocation Efficiency should always be less than or equals to Employing Error, so with the satisfaction of Employing Error and excess allocation of materials, Employing Efficiency Curve is on a downward trend and has dropped below zero, but it can reach zero in the end.
