简介招投标过程是形成建设项目中合作关系的关键.在招投标的过程中，业主在招标文件和合同中提出目标，要求和双方合作的模式，为了响应业主的要求，投标者根据其对项目的评估提出相应目标作出承诺。

工程双方的合作关系通过合同来反映和规定，并且在招投标过程中业主和投标者交换信息并订立合同。

然而，信息交换既不完整也不对称，业主为投标者构建了一个不对称的信息平台投标者也采取相应的措施。

2。

业主和投标者的不对称情况有明确和详细地在合同内容中提到，但它仍然是项目建设过程中的准则。

因此它不能违犯，因为双方都清楚它的存在。

推断合同是基于明示合同和一般默认合同合理和公正的解释，因此在项目施行过程中应当遵守。

在具体的项目环境下，推断合同可以作为双方的基础和标准。

与一般默认合同相比，推断合同更复杂，因为“这是基于合理推断的基础和标准”。
