Every year, the parties to construction projects dispute over the amount of billions, lost financial costs amount to 100 vis of millions, and the costs of lawyers increase and increase. 
It is stated by BDO 's Construction and Construction Analysis for 2025 found that the level of conflict is a key reason for the industry's low economic growth. In 2020, the National Audit Office issued a report after analysing legal conflicts in national road projects. A significant proportion of the dispute records were due to a lack of legal knowledge and understanding. 
The situation is probably the same in the construction industry.It is too wrong that the level of conflict and lack of economic growth should be due to lack of knowledge. 
CHAT BPJ is a tool everyone can use (builders and contractors) to increase contract understanding and reduce the level of conflict. The availability of relevant law is now marginal and the cost minimal.
