Discuss different methods applied to correct errors, clashes, and redlines using software designed to aid the accuracy of the following Computer Aided design, such as scheduling and modelling:

$1.$ CAD

$2.$ BIM

$3.$ Explain how software processes data collected by using instruments to process valuable information, such as surveying data, to create maps and plans.

$4.$ Discuss how engineering techniques contributed to element errors associated with inaccurate information due to difficulties reaching places or physical constraints and information assumed, such as drainage, inspection chambers, and inaccessible underground services.

$5.$ Human errors during setting$-$out using unverified drawings.

$6.$ Critically analyse the implications and constraints on the design phase and project overall due to errors that were not rectified.

$7.$ Analyse and assess the information, communication, and dealings during the project's life cycle
