In many construction sites, the Engineer’s staff issue verbal instructions at site to Contractor’s staff for work to be done and some of such instructions may include changes to the scope of work as agreed in contract documents. Contractors are obliged to follow such instructions and soon their staff start implementing the instructions issued but often without any written form of confirmation. This practice leads to disputes quite often and by the time the discussions take place on the disputes, it could be difficult to establish the origins of changes as there hadn’t been any written instructions.

It is therefore important to ensure that all communications are documented and all verbal agreements or instructions are confirmed in writing as soon as practicable. This includes situations that may not necessarily change the scope of work but may impact the means and methods of performing the work in the construction sites.
